Description

Technical Field

[0001] This application relates to the field of bearing manufacturing technology, specifically to a testing fixture for bearing manufacturing. Background Technology

[0002] After assembly, the runout of the bearing's outer and inner rings needs to be tested to ensure that the runout values ​​meet design requirements. Currently, when testing the runout of bearings, the inner and outer rings are often tested separately. This testing method increases the testing equipment, which occupies more space and wastes time. Alternatively, after the outer ring is tested, the outer ring is manually pressed and the inner ring is rotated to test the inner ring with a runout gauge. This testing method is prone to errors. Therefore, this application proposes a testing fixture for bearing production to solve these problems. Summary of the Invention

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 3 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0017] Please see Figure 1-4This application provides a technical solution for a bearing production testing fixture: A bearing production testing fixture includes a base plate 1, four support legs 2 at the bottom of the base plate 1, and an inner ring locking assembly on the base plate 1. The inner ring locking assembly includes an inner locking plate 3, a handwheel 4, a first lead screw 5, a lifting plate 6, a connecting block 8, and a linkage plate 9. The bottom of the first lead screw 5 is rotatably connected to the base plate 1, the handwheel 4 is provided on the upper surface of the first lead screw 5, the lifting plate 6 is screwed to the outside of the first lead screw 5, and at least three connecting blocks 8 are provided on the outside of the lifting plate 6. The linkage plate 9 is hinged to one side of the connecting block 8, and the inner locking plate 3 is hinged to the other end of the linkage plate 9. A first sliding groove 11 is provided on the base plate 1 corresponding to the inner locking plate 3. A T-shaped block 12 is slidably connected in the first sliding groove 11. The upper surface of the T-shaped block 12 is connected to the inner locking plate 3. A bearing 7 is provided on the outside of the inner locking plate 3, and an outer ring locking assembly is provided on the outside of the bearing 7.

[0018] Specifically, the width of the inner locking plate 3 is greater than the width of the first slide groove 11. One side of the inner locking plate 3 is arc-shaped, and the other side of the inner locking plate 3 is provided with a hinge plate. The handwheel 4 is fixed to the first lead screw 5 by bolts.

[0019] More specifically, the base plate 1 can accommodate two universal magnetic dial indicators, one for detecting the outer ring runout and the other for detecting the inner ring runout.

[0020] Furthermore, there are four connecting blocks 8, which are evenly distributed on the outside of the lifting plate 6, and the number of linkage plate 9 and inner locking plate 3 is the same as the number of connecting blocks 8.

[0021] Specifically, the connecting block 8 is welded onto the lifting plate 6.

[0022] With this configuration, the worker can rotate the handwheel 4, causing the first lead screw 5 to rotate. This causes the lifting plate 6 to move up and down along the first lead screw 5, which in turn causes the linkage plate 9 to move the inner locking plate 3 and the T-block 12 along the first slide groove 11. This adjusts the position of the inner locking plate 3 so that it can fix the inner ring of the bearing 7.

[0023] Furthermore, the linkage plate 9 has opening slots 10 on both sides. The opening slot 10 at one end of the linkage plate 9 is hinged to the connecting block 8, and the opening slot 10 at the other end of the linkage plate 9 is hinged to the hinge plate.

[0024] Furthermore, the outer ring locking assembly includes an outer locking plate 13, a movable plate 14, a second lead screw 15, a fixed plate 16, a guide groove 17, and a linkage assembly 18. Four guide grooves 17 are provided on the base plate 1. The guide grooves 17 are evenly distributed on the base plate 1 with the bearing 7 as the center. The outer locking plate 13 is slidably connected in the guide grooves 17. The movable plate 14 is provided at the bottom of the outer locking plate 13. The movable plate 14 is connected to the second lead screw 15 through a lead screw nut. One end of the second lead screw 15 is connected to the base plate 1 through the fixed plate 16, and the other end of the second lead screw 15 is rotatably connected to the linkage assembly 18.

[0025] Specifically, the outer locking plate 13 is fixed to the movable plate 14 by bolts, and the fixed plate 16 is fixed to the base plate 1 by bolts.

[0026] More specifically, there are four guide grooves 17, four fixed plates 16, four second lead screws 15, four moving plates 14 and four outer locking plates 13, and they are evenly distributed on the outside of the linkage group 18.

[0027] With this configuration, the linkage group 18 can drive the second lead screw 15 to rotate, thereby causing the second lead screw 15 to drive the moving plate 14 and the outer locking plate 13 to move along the guide groove 17, thus fixing the outer ring of the bearing 7.

[0028] Furthermore, the linkage assembly 18 includes a driven bevel gear 19, a driving bevel gear 20, a servo motor 21, and a linkage housing 22. The linkage housing 22 is located in the middle of the lower surface of the base plate 1. The bottom of the linkage housing 22 is provided with the servo motor 21. The power output end of the servo motor 21 extends into the linkage housing 22 and is connected to the driving bevel gear 20. The driving bevel gear 20 is meshed with four driven bevel gears 19 above it. One end of the driven bevel gear 19 is rotatably connected to the linkage housing 22, and the other end of the driven bevel gear 19 extends out of the linkage housing 22 and is connected to the second lead screw 15.

[0029] Specifically, the linkage shell 22 is fixed on the base plate 1, and the servo motor 21 is fixed on the linkage shell 22.

[0030] With this configuration, the servo motor 21 transmits power to the driving bevel gear 20, which in turn transmits power to the driven bevel gear 19. This causes the driven bevel gear 19 to drive the second lead screw 15 to rotate, which in turn causes the second lead screw 15 to move the moving plate 14 and the outer locking plate 13, thereby fixing the outer ring of the bearing 7 so that workers can check the runout value of the bearing 7.

[0031] In use: Place the bearing 7 onto the inner ring locking assembly, then turn the handwheel 4 to drive the first lead screw 5 to rotate, thereby causing the lifting plate 6 to move up and down along the first lead screw 5. This causes the linkage plate 9 to drive the inner locking plate 3 and the T-block 12 to move along the first slide groove 11, thereby adjusting the position of the inner locking plate 3 so that the inner locking plate 3 can fix the inner ring of the bearing 7. Then, the worker places the probe of the dial indicator on the outer ring of the bearing, and then rotates the outer ring of the bearing 7 to check the runout value of the outer ring.

[0032] When it is necessary to detect the inner ring runout value, the servo motor 21 drives the active bevel gear 20 to rotate, thereby transmitting power from the active bevel gear 20 to the driven bevel gear 19. This causes the driven bevel gear 19 to drive the second lead screw 15 to rotate, which in turn causes the second lead screw 15 to move the moving plate 14 and the outer locking plate 13 along the guide groove 17, thereby fixing the outer ring of the bearing 7. Then, the worker rotates the handwheel 4 to separate the inner locking plate 3 from the inner wall of the bearing 7. The probe of the dial indicator is then placed on the inner ring of the bearing 7, and the inner ring of the bearing 7 is rotated to detect the runout value of the inner ring.

[0033] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
