Description

Technical Field

[0001] This utility model relates to the field of bearing roller processing technology, and in particular to a fixture for applying PVD coating to the surface of bearing rollers. Background Technology

[0002] Roller bearings are a type of rolling bearing and are widely used components in modern machinery. They support rotating parts through rolling contact between their main components. Most roller bearings are now standardized and offer advantages such as low starting torque, high rotational accuracy, and ease of selection. Currently, when applying a PVD coating to the surface of bearing rollers, clamps are required to clamp and secure the rollers.

[0003] The existing Chinese patent with publication number CN220178710U discloses a fixture for machining bearing rollers. The existing technical solution has the following defects: Although the above technical solution uses a cylinder to drive the moving block to move vertically upward, and the moving block drives the push block to move synchronously, during the upward movement of the push block, the two clamping plates rotate around the pivot and move closer to each other, which can fix the bearing roller between the two clamping plates, the overall height of the fixture is fixed in the above technical solution. Therefore, it is impossible to adjust the height of the fixture according to different usage needs, which reduces its practicality. Utility Model Content

A synchronous wheel 14 is provided at one end of the outlet and support wheel 9, and a synchronous belt 19 is provided between the two synchronous wheels 14. The bearing roller is placed on the top surface of the support wheel 9 on the connecting frame 10. The electric telescopic rods 11 on both sides of the vertical plate 12 are opened. The electric telescopic rods 11 drive the push block 16 on the bottom surface of the clamping block 7 to move, so that the positioning wheel 8 at the top of the clamping block 7 moves. When the positioning wheel 8 abuts against the bearing roller on the top surface of the support wheel 9, the bearing roller can be automatically clamped and fixed. After clamping and fixing, the bearing roller can be coated with a coating using external equipment. The hydraulic telescopic rod 5 is opened, and the hydraulic telescopic rod 5 drives the push plate 4 to move. When the push plate 4 moves, it drives the support platform 2 above the push plate 4 to move, so that the height position of the support platform 2 can be adjusted to meet the usage requirements of different heights, which is beneficial to improving its practicality.

[0028] In one embodiment, a limiting block 3 is provided at the middle position of both sides of the push plate 4, and one end of the limiting block 3 extends into the interior of the limiting groove 18 opened on both sides of the inner wall of the housing 1. The use of the limiting block 3 and the limiting groove 18 can limit the push plate 4, thereby facilitating the maintenance of the stability of the push plate 4 during movement.

[0029] In one embodiment, the limiting block 3 and the limiting groove 18 are rectangular structures. One end of the limiting block 3 extends into the interior of the limiting groove 18 and is slidably connected to the limiting groove 18, so that the limiting block 3 can move in the limiting groove 18, thereby limiting the push plate 4.

[0030] In one embodiment, the positioning wheel 8 is matched with the support wheel 9. By opening the motor 13 located in the middle of the bottom surface of the push plate 4, the motor 13 drives the synchronous wheel 14 to rotate. Then, by using the synchronous belt 19, the support wheel 9 in the connecting frame 10 can be driven to rotate. While the support wheel 9 is rotating, the positioning wheel 8 on the clamping block 7 can be used to make the bearing roller rotate, thereby adjusting the position of the bearing roller and facilitating the coating process of the bearing roller from all directions.

[0035] Working principle:

[0036] In use, the bearing roller is placed on the top surface of the support wheel 9 on the connecting frame 10. The electric telescopic rods 11 on both sides of the vertical plate 12 are opened. The electric telescopic rods 11 drive the push block 16 on the bottom surface of the clamping block 7 to move, so that the positioning wheel 8 at the top of the clamping block 7 moves. When the positioning wheel 8 abuts against the bearing roller on the top surface of the support wheel 9, the bearing roller is automatically clamped and fixed. After clamping and fixing, the bearing roller can be coated using external equipment. In this process, the hydraulic telescopic rod 5 is opened, which drives the push plate 4 to move. As the push plate 4 moves, the support platform 2 above the push plate 4 moves. The support platform 2 can be moved to adjust its height to meet different height requirements, thus improving its practicality. After the bearing rollers are clamped and fixed, the motor 13 located in the middle of the bottom surface of the push plate 4 is opened. The motor 13 drives the synchronous pulley 14 to rotate, and through the use of the synchronous belt 19, the support roller 9 in the connecting frame 10 can be rotated. While the support roller 9 is rotating, the positioning wheel 8 on the clamping block 7 can also be used to rotate the bearing rollers, thereby adjusting the position of the bearing rollers. This facilitates the coating process on the bearing rollers from all directions, which helps to improve its working efficiency.
