Technical Field

The invention relates to the technical field of boring machine processing, and in particular to a boring machine device based on large-diameter deep hole processing.

Background Art

With the continuous advancement of science and technology, especially in the field of automation and precision manufacturing, large-diameter deep hole processing technology has developed into a highly integrated field, which relies on advanced CNC technology, precision measurement technology, material science, mechanical design, automation and robotics technology, sensor technology, data processing and analysis, software application, thermal management, tool technology and intelligent manufacturing and other key technologies.

Although the existing technology has made remarkable achievements in the field of large-diameter deep hole processing, it still has some limitations and shortcomings. For example, high-precision processing equipment is often expensive, which limits its popularity in small and medium-sized enterprises; although the degree of automation is high, manual intervention may still be required in complex or variable processing tasks to cope with unpredictable situations; some equipment lacks flexibility and adaptability, and it is difficult to quickly adjust to workpieces of different materials or shapes; sensors and measurement technologies may have limited stability and accuracy under extreme working conditions; in addition, for the processing of some special materials, existing tool materials and coating technologies may not meet the requirements of long life and efficient cutting. Although intelligent manufacturing and data analysis technologies are advancing, there is still a long way to go to achieve fully intelligent adaptive control. These shortcomings have promoted the continuous innovation and development of technology in order to achieve higher processing efficiency, better processing quality and a wider range of applications.

Summary of the invention

To this end, the present invention provides a boring machine device based on large-diameter deep hole processing, which is used to overcome the problem in the prior art that the processing range is narrow due to adaptability limitations, resulting in unstable processing accuracy of large-diameter deep hole boring.

To achieve the above object, the present invention provides a boring machine device based on large-diameter deep hole processing, comprising:

A workbench, on which a fixture is arranged, the workbench is used to drive the fixture to move horizontally along the main axis direction of the bed, and the fixture is used to clamp the workpiece to be processed;

A tool, arranged on a spindle on the bed, for boring the workpiece to be processed as the spindle rotates;

A measuring module, used to monitor the real-time dimensional accuracy, real-time surface finish and hardness uniformity of the workpiece to be processed;

A numerical control module is arranged at the rear end of the bed, and is respectively connected to the workbench, the spindle and the measuring module, and is used to make a judgment according to the real-time dimensional accuracy and the preset first standard accuracy range, and adjust the moving speed of the workbench or the rotating speed of the spindle according to the judgment result;

The numerical control module is also used to make a determination based on the real-time dimensional accuracy of the workpiece to be processed whose real-time dimensional accuracy is within the first standard accuracy range and the preset second standard accuracy range, and adjust the cutting amount or cutting angle of the tool according to the determination result;

The numerical control module is also used to make a determination based on the real-time surface finish of the workpiece to be processed whose real-time dimensional accuracy is within the second standard accuracy range and the preset standard finish, and adjust the clamp pressure according to the determination result;

The standard correction module is connected to the numerical control module and the measurement module respectively, and is used to adjust the first standard accuracy range or the second standard accuracy range according to the hardness uniformity and the preset standard uniformity.

Furthermore, the CNC module determines that a workpiece to be processed whose real-time dimensional accuracy is not within a preset first standard accuracy range has a rough processing deviation, and determines that a workpiece to be processed whose real-time dimensional accuracy is greater than the maximum value of the preset first standard accuracy range needs to adjust the moving speed of the worktable.

Furthermore, when the real-time dimensional accuracy is greater than the maximum value of a preset first standard accuracy range, the numerical control module adjusts the moving speed of the workbench according to the real-time dimensional accuracy and the maximum value of the first standard accuracy range.

Furthermore, the numerical control module determines that the workpiece to be processed whose real-time dimensional accuracy is less than the minimum value of a preset first standard accuracy range needs to adjust the rotation speed of the spindle.

Furthermore, the numerical control module increases and adjusts the rotation speed of the spindle according to the real-time dimensional accuracy and the minimum value of the first standard accuracy range.

Furthermore, the CNC module determines that a workpiece to be processed whose real-time dimensional accuracy is not within a preset second standard accuracy range has a semi-precision processing deviation, and determines that a workpiece to be processed whose real-time dimensional accuracy is greater than the maximum value of the preset second standard accuracy range needs to adjust the cutting amount of the tool.

Furthermore, when the real-time dimensional accuracy is within a first standard accuracy range and higher than a second standard accuracy range, the numerical control module increases and adjusts the cutting amount of the tool.

Furthermore, the CNC module determines that the workpiece to be processed whose real-time dimensional accuracy is less than the minimum value of a preset second standard accuracy range needs to adjust the cutting angle of the tool, and adjusts the cutting angle of the tool according to the real-time dimensional accuracy and the minimum value of the second standard accuracy range.

Furthermore, the numerical control module determines that the real-time surface finish is greater than a preset standard finish and there is a finishing deviation, and adjusts the clamp pressure according to the real-time surface finish and the standard finish.

Furthermore, the standard correction module calculates the difference between the hardness uniformity greater than the preset standard uniformity and the standard uniformity, and in the case where the difference is determined to be greater than the preset first standard deviation, increases and adjusts the first standard accuracy range according to the difference and the first standard deviation;

The standard correction module adjusts the second standard accuracy range according to the difference value and the second standard deviation value when the difference value is less than or equal to the first standard deviation value and greater than the preset second standard deviation value;

The first standard accuracy range is greater than the second standard accuracy range.

Compared with the prior art, the beneficial effect of the present invention is that an automated and intelligent processing flow is realized through the collaborative work of a series of precision-controlled modules. First, the workbench clamps the workpiece and moves horizontally to meet the processing requirements. The tool is installed on the spindle and cuts as the spindle rotates. The measurement module monitors the dimensional accuracy, surface finish and hardness of the workpiece in real time, and feeds the data back to the CNC module. The CNC module compares these data with the preset standards, automatically adjusts the moving speed of the workbench, the rotation speed of the spindle, the cutting amount and angle of the tool, and the pressure of the fixture to ensure the accuracy and quality of the processing process. When the CNC module determines that the processing has achieved the expected accuracy and surface quality, it controls the workbench and spindle to stop moving and complete the processing. In addition, the standard correction module adjusts the accuracy standard range according to the hardness uniformity to adapt to different processing conditions, effectively solving the problem of unstable processing accuracy of large-diameter deep hole boring.

Furthermore, the real-time dimensional accuracy of the workpiece is accurately monitored through its CNC module. When it is detected that the dimensional accuracy exceeds the preset first standard accuracy range, the system automatically determines and takes corresponding measures: if the dimensional accuracy exceeds the maximum value, the moving speed of the worktable is adjusted to correct the deviation; if the dimensional accuracy is lower than the minimum value, the rotation speed of the spindle is adjusted to ensure the processing accuracy. By adjusting the operating parameters of the worktable and spindle in real time, the equipment can quickly respond to dimensional deviations and realize instant correction during roughing and semi-finishing.

Furthermore, the CNC module monitors the dimensional accuracy of the workpiece in real time and intelligently identifies whether it exceeds the second standard accuracy range, thereby determining whether the workpiece has a semi-precision processing deviation. When the real-time dimensional accuracy exceeds the maximum value of the range, the CNC module automatically adjusts the cutting amount of the tool to ensure that the processing process can respond quickly and correct the deviation. On the contrary, when the dimensional accuracy is lower than the minimum value, the system adjusts the cutting angle of the tool to fine-tune the processing accuracy. By automatically adjusting the cutting amount and angle to adapt to different processing requirements, ensure that the workpiece meets high-precision standards.

Furthermore, the CNC module is responsible for monitoring the real-time surface finish of the workpiece. Once it is found that it exceeds the preset standard finish, the system determines that there is a finishing deviation and adjusts the fixture pressure accordingly to improve the surface quality. At the same time, the standard correction module evaluates the difference between the hardness uniformity of the workpiece and the preset standard uniformity. When the difference exceeds the first standard deviation value, the module will adjust the first standard accuracy range; if the difference is between the first and second standard deviation values, the second standard accuracy range will be adjusted. Such graded adjustments ensure that the processing process can flexibly adapt to different accuracy requirements. By automatically adjusting the fixture pressure and accuracy range, the equipment not only improves processing efficiency and reduces the need for manual intervention, but also reduces material waste and scrap rate caused by improper processing.

The present embodiment provides a boring machine device for large-diameter deep hole processing, including a worktable 1, a workpiece to be processed 2, a fixture 3, a tool 4, a bed 5, a spindle 6, a measuring module 7, a CNC module 8, and a standard correction module (not shown in the figure), wherein:

A workbench 1 is arranged on the bed 5 and is used to move forward and backward in the horizontal direction to clamp a fixture 3 for clamping a workpiece 2 to be processed;

A tool 4 is arranged on a spindle 6 on the bed 5 and is used for boring as the spindle 6 rotates;

A measuring module 7, used to monitor the real-time dimensional accuracy, real-time surface finish and hardness uniformity of the workpiece 2 to be processed;

A numerical control module 8 is arranged at the rear end of the bed 5, and is respectively connected to the workbench 1, the spindle 6 and the measuring module 7, and is used to make a judgment based on the real-time dimensional accuracy and the preset first standard accuracy range, and adjust the moving speed of the workbench 1 or the rotating speed of the spindle 6 according to the judgment result;

The numerical control module 8 is also used to make a judgment based on the real-time dimensional accuracy of the workpiece 2 to be processed whose real-time dimensional accuracy is within the first standard accuracy range and the preset second standard accuracy range, and adjust the cutting amount of the tool 4 or the cutting angle of the tool 4 according to the judgment result;

The numerical control module 8 is also used to make a determination based on the real-time surface finish of the workpiece 2 to be processed whose real-time dimensional accuracy is within the second standard accuracy range and the preset standard finish, and adjust the clamp pressure according to the determination result;

The numerical control module 8 is also used to determine whether the processing is completed according to the real-time surface finish and real-time dimensional accuracy of the workpiece 2 to be processed, and control the workbench 1 and the spindle 6 to stop moving according to the result of determining that the processing is completed;

The standard correction module is connected to the numerical control module 8 and the measuring module 7 respectively, and is used to adjust the first standard accuracy range according to the hardness uniformity and the preset standard uniformity, or adjust the second standard accuracy range.

Through the collaborative work of a series of precision-controlled modules, an automated and intelligent processing process is realized. First, the workbench 1 clamps the workpiece and moves horizontally to meet the processing requirements. The tool 4 is installed on the spindle 6 and cuts as the spindle 6 rotates. The measurement module 7 monitors the dimensional accuracy, surface finish and hardness of the workpiece in real time, and feeds the data back to the CNC module 8. The CNC module 8 compares these data with the preset standards, and automatically adjusts the moving speed of the workbench 1, the rotation speed of the spindle 6, the cutting amount and angle of the tool 4, and the pressure of the fixture 3 to ensure the accuracy and quality of the processing process. When the CNC module 8 determines that the processing has achieved the expected accuracy and surface quality, it controls the workbench 1 and the spindle 6 to stop moving and complete the processing. In addition, the standard correction module adjusts the accuracy standard range according to the hardness uniformity to adapt to different processing conditions.

For example, in a high-precision manufacturing environment, especially for industrial applications that require large-diameter deep-hole machining:

Workpiece information: The workpiece is an aluminum alloy cylinder with a diameter of 500mm and a length of 2000mm. The inner hole needs to be processed to a diameter of 480mm and a length of 2000mm.

Device Setup:

Workbench 1: Automatic clamping system, load-bearing capacity up to 2 tons.

Tool 4: High-precision boring tool, suitable for large-diameter deep hole processing.

Measuring module 7: A high-precision laser measurement system that can monitor dimensional accuracy and surface finish in real time; and an ultrasonic hardness tester that can measure hardness by measuring the propagation speed of ultrasonic waves in the material, V=L/t, where V is the propagation speed, L is the measurement distance, and t is the detection time. According to the propagation speed and the known relationship between hardness and sound speed established based on experimental data, several hardness values of the material surface are converted, and the hardness uniformity is obtained by statistical analysis of several hardness values.

Preset standard values for CNC module 8 and standard correction module:

The first standard accuracy range: dimensional accuracy is between +0.05mm and -0.05mm.

Maximum value: +0.05mm

Minimum value: -0.05mm

The second standard accuracy range: dimensional accuracy is between +0.02mm and -0.02mm.

Maximum value: +0.02mm

Minimum value: -0.02mm

Standard finish: surface roughness Ra value is 0.4μm.

Hardness uniformity: Hardness uniformity is 55HRC, and the allowable fluctuation range is ±2HRC.

First standard deviation: The difference between hardness uniformity and standard uniformity is greater than 3HRC.

Second standard deviation: The difference between hardness uniformity and standard uniformity is between 1HRC and 3HRC.

Specific implementation steps:

The workpiece is fixed on the workbench 1 and the measuring module 7 is started to perform initial measurement.

According to the initial measurement result, the numerical control module 8 determines whether the dimensional accuracy is within the first standard accuracy range.

If the dimensional accuracy exceeds the first standard accuracy range, the numerical control module 8 adjusts the moving speed of the workbench 1 or the rotating speed of the spindle 6 to correct the deviation.

When the dimensional accuracy enters the first standard accuracy range, the numerical control module 8 further determines whether it is within the second standard accuracy range.

If the dimensional accuracy exceeds the second standard accuracy range, the numerical control module 8 adjusts the cutting amount or cutting angle of the tool 4 .

At the same time, the CNC module 8 monitors the surface finish and adjusts the clamp pressure if the surface finish exceeds the standard finish.

The standard correction module adjusts the first and second standard accuracy ranges according to the difference between the hardness uniformity and the preset standard uniformity.

In large-diameter deep hole boring machine equipment, the setting of various parameters usually depends on the following factors:

Travel speed: Depends on the size of the workpiece, material hardness, processing depth and required processing accuracy. Usually set based on experience and equipment capabilities.

Rotational speed: Depends on the tool material, workpiece material and desired surface finish. Rotational speed affects the amount of stock removal and heat generation.

The first standard accuracy range is usually wider than the second standard accuracy range and is used in the rough machining stage to ensure that the workpiece size is within a looser tolerance range.

Second standard accuracy range: stricter than the first standard accuracy range, used in the finishing stage to ensure that the workpiece size is close to the design requirements.

Cutting amount: depends on the workpiece material, tool material, cutting depth and feed speed.

Cutting angle: Depends on the type of tool, workpiece material and required surface finish.

Real-time surface finish: Monitored in real time by the measurement module 7, reflecting the roughness of the current workpiece surface.

Standard finish: set according to the application requirements and industry standards of the workpiece.

Clamp pressure: Depends on workpiece material and required clamping stability.

Hardness uniformity: reflects the consistency of the workpiece material and affects the processing process and accuracy.

Beneficial effects of the preset values in this embodiment:

Balance efficiency and precision: Moderate moving speed and rotation speed can ensure processing efficiency while reducing the quality degradation caused by excessive speed.

Strong adaptability: The settings of the first and second standard accuracy ranges enable the equipment to adapt to the processing requirements of different stages, with a smooth transition from rough machining to fine machining.

Improve machining quality: By dynamically adjusting the cutting amount and cutting angle, the cutting conditions can be optimized and the surface defects of the workpiece can be reduced.

Ensure workpiece stability: Appropriate clamp pressure can prevent the workpiece from vibrating or displacing during machining and improve machining accuracy.

Flexibility: The monitoring of hardness uniformity and the application of standard correction modules enable the equipment to adapt to changes in material properties and improve the flexibility and reliability of the processing process.
