Description

A method for detecting the deployment effect of a contact steel ball deployment mechanism

technical field

The invention relates to a method for detecting the deployment effect of a deployment mechanism, in particular to a method for detecting the deployment effect of a contact steel ball deployment mechanism.

Background technique

Steel balls are the main parts of bearings, and their surface defects have a vital impact on the accuracy, running performance and service life of bearings. Initially, in the bearing industry, the detection of surface defects of steel balls still used the traditional manual visual inspection method, and its accuracy and stability were difficult to guarantee. Later, many scholars set foot in the research field of steel ball surface defect detection, invented or developed many steel ball spherical surface expansion devices, which are used in the factory to detect steel balls, such as meridian expansion mechanism, expansion disc friction disc expansion mechanism, etc.

The deployment effect of the deployment device directly affects the detection of steel balls. Therefore, during the production inspection process in the factory, the deployment effect must be checked each time the deployment device is turned on. By checking the deployment effect, it can be judged whether the deployment mechanism is in a state where it can hold the steel ball. The normal state of the ball fully expanded in order to obtain more accurate detection data.

Contents of the invention

The object of the present invention is to provide a method for detecting the deployment effect of a contact steel ball deployment mechanism, which is intuitive, convenient, low cost and good in effect.

The technical solution adopted by the present invention to solve the technical problem is: a method for detecting the deployment effect of the contact steel ball deployment mechanism, the steps of which are as follows:

1) Put the qualified steel ball into the feeding mechanism;

2) Evenly coat a layer of fluorescent powder on the surface of the friction disc;

3) Start the machine, the unfolding mechanism unfolds the surface of the steel ball and at the same time the phosphor adheres to the surface of the steel ball along the unfolding track;

4) After unfolding, take the steel ball with fluorescent powder into the dark box for observation. If the surface of the steel ball is glowing and the light is even, it means that the phosphor powder has covered the surface of the steel ball, and the unfolding effect of the unfolding mechanism is good; if the surface of the steel ball is glowing Uneven, or some places do not emit light, indicating that the fluorescent powder is not covered on the surface of the steel ball, and the unfolding effect of the unfolding mechanism is not good;

5) If the unfolding effect is not good, adjust the relevant parameters of the unfolding mechanism, and repeat the above steps until the fluorescent powder is covered on the surface of the steel ball and the unfolding effect of the unfolding mechanism is good.

The beneficial effect of the present invention is that: the present invention utilizes the characteristic of fluorescent powder to emit light in the dark to detect the unfolding effect of steel balls, which is intuitive, convenient, fast, low in cost and good in effect.

In the figure: 1 feeding mechanism, 2 steel balls, 3 unfolding disk, 4 friction disk, 5 the first stepping motor, 6 the second stepping motor, 7 linear guide rail, 8 the third stepping guide rail, 9 fluorescent powder, 10 dark box , 11 observation holes.

Detailed ways

As shown in Figure 1, the method for detecting the deployment effect of the contact steel ball deployment mechanism of the present invention has the following steps:

1) Put the qualified steel ball 2 into the feeding mechanism 1;

2) uniformly coat a layer of fluorescent powder 9 on the surface of the friction disc 4;

3) Start the machine, the feeding mechanism 1 starts feeding, and the unfolding disk 3 starts to rotate under the drive of the first stepping motor 5, and the steel ball 2 falling on the unfolding disk 3 is rotated to the contact with the friction disk 4, and at the same time , the friction disc 4 is also rotating under the drive of the second stepping motor 6, and the third stepping motor 8 located on the linear guide rail 7 drives the friction disc 4 to move up and down, so that the unfolding mechanism carries out the movement on the surface of the steel ball 2 While unfolding, the phosphor powder 9 is also attached to the surface of the steel ball 2 along the unfolding track;

4) After the deployment is completed, take the steel ball 2 with the fluorescent powder 9 attached to it into the dark box 10 and observe through the observation hole 11. If the surface of the steel ball 2 emits light evenly, it means that the surface of the steel ball 2 is covered with the fluorescent powder 9 , the unfolding effect of the unfolding mechanism is good; if the surface of the steel ball 2 emits light unevenly, or some places do not emit light, it means that the phosphor 9 is not covered with the surface of the steel ball 2, and the unfolding effect of the unfolding mechanism is not good;

5) If the unfolding effect is not good, then it is necessary to adjust the relevant parameters of the unfolding mechanism, and then repeat the above steps until the surface of the steel ball 2 is covered with fluorescent powder 9 and the unfolding effect of the unfolding mechanism is good.

Except for the technical features described in the instructions, all are known technologies by those skilled in the art.
