Description
Technical field
The present invention relates to a kind of machine tool component, particularly a kind of planer type numerical control cutting machine basic components.
Background technology
Along with the development of modern mechanical processing industry, people improve constantly the requirement of cut quality, precision and the production efficiency of sheet material, make the Numerical control cutting technology be able to fast development.But still there is more problem in existing numerical control cutting machine; Mainly contain: integrated costs such as (1) guider complex structure and purchase, installation, maintenance are high; This device adopts two square ball line slideways usually, makes the lifting body fixed head realize rectilinear motion through two slide blocks that are fixed on the line slideway; (2) line slideway assembling difficulty; Complex procedures is difficult to guarantee the depth of parallelism of linearity and two line slideways of single line slideway, in the line slideway process is installed; Every line slideway all needs 22 ~ 25 screws to fix that (the screw number depends on the physical length of line slideway; Screw number when this routine cut-off line rail length is 3.6m), make line slideway have the certain linearity and the depth of parallelism, must guarantee on the crossbeam screwed hole point-blank and be parallel to each other; Consider the clearance fit relationship of each screw and line slideway simultaneously, when tightening a screw, all need the linearity and the depth of parallelism of alignment guide rail at every turn; (3) traditional numerical control cutting machine also has transmission not steady, and cutting accuracy is low, and noise is big; Defectives such as reliability is low, the assembly process of said structure decision has very big influence to the linearity and the depth of parallelism of line slideway, thereby causes transmission not steady; Creep; Cutting accuracy is low, and in this process, produces a large amount of noises, can directly destroy slide block under the serious situation.
In addition, the domestic industry standard that does not also have to be directed against specially at present the numerical control cutting machine cutting accuracy, temporary transient reference " thermal cutting plasma cut quality and dimensional discrepancy " is industry standard (JB/T10045.4-1999), and the cutting accuracy of this standard definition is 0.5mm.
Summary of the invention
The present invention mainly is the deficiency that exists in the existing planer type numerical control cutting machine technology for solving: complex structure, and during installation fee, steadily noise is not big in transmission, and cutting accuracy is low.
The technical scheme that the present invention adopts is: a kind of planer type numerical control cutting machine crossbeam base apparatus; The basis crossbeam is provided with line slideway; The line slideway both sides are fixed with guide rod, and the lift fixed head rolls on line slideway through roller shaft and roller, and roller cooperates with guide rod.Wherein, change traditional bilinear guide rail into a monoblock type line slideway, be fixed on a side of basic crossbeam, guide rod is separately fixed at the both sides of line slideway, and roller rolls on guide rod.Line slideway aluminium alloy material; And with the width of basic crossbeam matching part than the wide 2 ~ 3mm of the width of basic crossbeam; Roller is selected the GCr15 bearing steel for use, and the lift fixed head rolls on line slideway through roller shaft and roller, and roller quadrate on perpendicular is arranged.
The present invention adopts the monoblock type line slideway, and it is easy for installation, and the location accurately; The stable drive noise is low, and the linearity and the depth of parallelism obviously improve, and line slideway adopts aluminum alloy materials; Improved the linearity and the depth of parallelism, reduced crossbeam weight, during for fear of the shake of basic crossbeam to the influence of line slideway; Width widen 2 ~ 3mm line slideway guarantees its linearity and the depth of parallelism, improves the cutting accuracy of numerical control cutting machine; The lift fixed head adopts the roller type transmission, and the material of roller is the GCr15 bearing steel, and simple with traditional slide block type transmission structure compared, transmission is more steady, and is easy installation and reliable.
The present invention compares with existing planer type numerical control cutting machine crossbeam base apparatus, and novel structure is simple, installs fast accurately; Cutting accuracy is high; The stable drive noise is low, can produce good economic benefit, for the development of high accuracy planer type numerical control cutting equipment provides guarantee.This design changes traditional bilinear guide rail into the monoblock type line slideway; Its linearity and the depth of parallelism have direct influence to transmission stability and cutting accuracy; Use the linearity and the depth of parallelism that this monoblock type line slideway can better guarantee the crossbeam transmission; And assembly process is very easy; The staff only need guarantee line slideway apart from the distance of beam-end this line slideway " edge " on crossbeam, get final product through the screw of both sides is fixing, and its linearity and the depth of parallelism are determined by line slideway self fully.Pass through verification experimental verification: the numerical control cutting machine stable drive that adopts this to improve design is reliable, the generation of well having stopped creeping phenomenon; Its cutting accuracy is brought up to 0.2mm by original 0.5mm; The equipment running noises is reduced to the 58.6dB decibel by original 76.2dB's, has reduced by 76.9%, reaches the industrial area Standard of Environmental Noise of national regulation.Aspect economic benefit, though the price of a monoblock type line slideway is 2 times of original line slideway, from aspect analysis-by-synthesis such as installation cost input, later maintenance inputs, the monoblock type line slideway is efficiently more economical.
