A method for measuring the position of a self-aligning roller spherical surface using a three-dimensional optical image projector

Abstract

A method for measuring the spherical position of self-aligning rollers using a three-dimensional optical image projector, relating to the field of bearing measurement technology. This method addresses the problems of inaccurate measurements and low efficiency caused by the drum-shaped structure of the self-aligning rollers and the arc-shaped reference end face, which makes alignment difficult in traditional methods. The method using a three-dimensional optical image projector improves both accuracy and efficiency. Since the measurement of the spherical position of the self-aligning rollers is performed using measurement software, and the actual measurement process involves automatic measurement after the self-aligning rollers are positioned, the machine automatically calculates the results, resulting in more accurate and efficient measurements. This method for measuring the spherical position of self-aligning rollers using a three-dimensional optical image projector has been applied to the measurement of multiple product models, improving versatility and significantly enhancing measurement efficiency and accuracy. This invention is applicable to the measurement of self-aligning rollers.

Description

Technical Field

[0001] This invention relates to the field of bearing measurement technology, and specifically to a method for measuring the position of a self-aligning roller spherical surface using a three-dimensional optical image projector. Background Technology

[0002] Self-aligning roller bearings have two rows of rollers and mainly bear radial loads, but can also bear axial loads in any direction. The spherical position of the self-aligning rollers is mainly to ensure the correct contact angle between the self-aligning rollers and the inner and outer rings. The accuracy of the spherical position of the self-aligning rollers affects the service life of the bearing.

[0003] The traditional method for measuring the spherical position of a self-aligning roller involves fixing the roller to the V-shaped worktable of a profilometer using two steel balls with diameters close to that of the roller. The profilometer is then used to measure the contours of the steel balls and the roller, and the coordinates of their centers within the profilometer are analyzed. Since the diameter of the steel balls is known, the position of the roller's spherical surface is obtained by subtracting the coordinates of the steel balls and their radius from the coordinates of the roller. However, because the self-aligning roller has a drum-shaped structure and a curved reference end face, it is difficult to align properly, resulting in inaccurate measurements, low efficiency, and an inability to meet the needs of batch on-site testing.

[0004] In summary, traditional measurement methods suffer from inaccurate measurements and low efficiency because the self-aligning roller has a drum-shaped structure and the reference end face is arc-shaped, making alignment difficult. Summary of the Invention

[0005] This invention addresses the problem of inaccurate measurements and low efficiency caused by the drum-shaped structure of the self-aligning roller and the arc-shaped reference end face in traditional measurement methods. Instead, it proposes a method for measuring the spherical position of the self-aligning roller using a three-dimensional optical image projector.

[0006] The present invention provides a method for measuring the position of a self-aligning roller spherical surface using a three-dimensional optical image projector, the specific method of which is as follows:

[0007] Step 1: Wipe the end face of the self-aligning roller and the surface of the busbar with an alcohol swab and a lint-free cloth;

[0008] Step 2: Use a flat-jaw bench vise to fix and clamp the self-aligning roller. During the clamping process, place the gauge block on the large end face of the self-aligning roller and then clamp it in place.

[0009] Step 3: Based on the clamping method of the self-aligning rollers in Step 2, and on the premise of ensuring clear measurement images, select a three-dimensional optical image projector to project and measure the self-aligning rollers.

[0010] Step 4: After the self-aligning rollers are clamped, and under the condition that the projected image is clear, position the self-aligning rollers according to their structural characteristics.

[0011] Step 5: After positioning the self-aligning roller, take a measurement. After the measurement is completed, repeat the workpiece positioning steps when measuring the next self-aligning roller. After the workpiece positioning is completed, call the measurement program and measure directly.

[0012] Furthermore, the specific method for positioning the self-aligning rollers in step four is as follows:

[0013] Step 4: Select the generatrices of the self-aligning roller generatrices and the gauge block generatrices as the positioning points of the self-aligning rollers.

[0014] Step 42: Select the diagonal positioning function of the measurement software to make the two sides of the diagonal positioning coincide with the generatrices of the self-aligning roller generatrices and the gauge block generatrices, respectively.

[0015] Step 4: Then, reset the X, Y, and Z coordinates of the workpiece to zero, thereby completing the positioning of the self-aligning roller;

[0016] Furthermore, the specific method for measurement in step five is as follows:

[0017] Step 51: Select the maximum magnification of the image and perform the measurement in semi-automatic mode;

[0018] Step 5.2: First, measure the projected straight line 1 of the gauge block that is in contact with the end face of the self-aligning roller;

[0019] Step 53: Then measure the first and second arcs of the projection of the left and right generatrices of the self-aligning rollers. Construct a straight line 2 using the centers of the first and second arcs. Then calculate the width between the straight line 1 and the straight line 2 using a soft command. This is the spherical position of the self-aligning roller.

[0020] Furthermore, the first arc in step five three is the arc at the top of the transverse section of the self-aligning roller;

[0021] Furthermore, the second arc in step five-three is the arc at the bottom of the transverse cross-section of the self-aligning roller;

[0022] Furthermore, after completing the measurement process from step one to step five, save the measurement results and print out the measured data.

[0023] Compared with the prior art, the present invention has the following advantages:

[0024] This invention overcomes the shortcomings of existing technologies by using a three-dimensional optical image projector to measure the position of a self-aligning roller spherical surface, thus improving measurement accuracy and efficiency. Because the measurement of the self-aligning roller spherical surface position is performed using measurement software, and the actual measurement process involves positioning the self-aligning rollers, automatic measurement and machine calculation are achieved, resulting in more accurate and efficient measurements. This method of measuring the position of a self-aligning roller spherical surface using a three-dimensional optical image projector has been applied to the measurement of multiple product models, improving versatility and significantly enhancing measurement efficiency and accuracy.
