[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1 to 4 In an embodiment of the utility model, a bearing ring processing fixture includes two fixed plates 1, a rotating shaft 6 is fixedly installed at the center of one end of the fixed plate 1 at the back end, a worm gear 11 is rotatably installed between the two fixed plates 1, and a clamping mechanism is installed on the fixed plate 1 and the worm gear 11. The clamping mechanism is used to clamp bearing rings of different diameters. A rotating mechanism is installed between the outer periphery of the worm gear 11 and the two fixed plates 1. The rotating rotating mechanism is used to drive the clamping mechanism to move. The clamping mechanism includes a clamping assembly and a protective assembly. The protective assembly is sleeved on the outer wall of the clamping assembly.

[0021] In this embodiment: when the outer periphery of the inner ring is processed to form a raceway, one end of the inner ring is first fitted with the fixed plate 1 at the front end. At this time, the clamping assembly is located in the circular hole of the inner ring. Then, by rotating the rotating mechanism, the rotating mechanism drives the clamping assembly of the clamping mechanism to clamp the inner ring. At the same time, the protective assembly can prevent the clamping assembly from being hard squeezed with the inner wall of the inner ring.

[0022] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The clamping assembly includes a strip groove 2 opened on the outer periphery of the fixed plate 1, and the number of the strip grooves 2 is multiple, and the multiple strip grooves 2 are equidistantly distributed in the circumferential direction on the fixed plate 1. The clamping assembly also includes an arc groove 12 opened on the worm gear 11, and the number of the arc grooves 12 is multiple, and the multiple arc grooves 12 are equidistantly distributed in the circumferential direction. The clamping assembly also includes a movable column 10 movably connected to the strip groove 2 and the inner wall of the arc groove 12. An anti-slip plate 5 is integrally formed at one end of the movable column 10, and a clamping rod 8 is integrally formed at the other end of the movable column 10. An inwardly recessed docking groove 9 is opened at one end of the clamping rod 8. The diameter of the clamping rod 8 and the diameter of the anti-slip plate 5 are larger than the diameter of the clamping rod 8.

[0023] In this embodiment: a tool is used to rotate the rotating mechanism, and the rotating mechanism drives the worm gear 11 to rotate, and the rotating worm gear 11 drives the arc groove 12 inside it to rotate. At this time, the arc groove 12 is an eccentric arc structure, so the rotating arc groove 12 will squeeze the movable column 10, and the compressed movable column 10 moves axially along the strip groove 2. Therefore, the axially moving movable column 10 can drive the anti-slip plate 5 and the clamping rod 8 connected thereto to move synchronously, and the clamping rod 8 can clamp the inner ring internally. The setting of the anti-slip plate 5 can prevent the clamping rod 8 from separating from the arc groove 12 and the strip groove 2.

[0024] Please refer to Figure 3 The protective assembly includes a rubber protective sleeve 4 sleeved on the outer wall of the clamping rod 8, and the inner wall of the rubber protective sleeve 4 is integrally formed with a rubber plate 7 that is clamped with the docking groove 9.

[0025] In this embodiment: when the bearing ring is clamped, the rubber protective sleeve 4 is in direct contact with the bearing ring, which can avoid the clamping rod 8 from being directly squeezed against the bearing ring. At the same time, the rubber protective sleeve 4 can increase the contact area with the clamping rod 8 through the docking groove 9 and the rubber plate 7, thereby further increasing the contact force and avoiding the rubber protective sleeve 4 from falling off during the idling test of the device.

[0026] Please refer to Figure 4 The rotating mechanism includes a shell 3 integrally formed between the outer peripheries of the two fixed plates 1, a worm 14 is rotatably installed between the top end plate and the bottom end plate of the shell 3, and a docking head 15 is integrally formed at the top of the worm 14 and penetrates to the top of the shell 3. The docking head 15 is rotatably connected to the shell 3. The rotating mechanism also includes a tooth block 13 integrally formed on the outer periphery of the worm wheel 11, and multiple tooth blocks 13 are equidistantly distributed in the circumferential direction. The tooth blocks 13 are meshed with the spiral portion of the outer periphery of the worm 14, and a rubber friction pad is provided at the rotation position between the outer periphery of the docking head 15 and the shell 3.

[0027] In this embodiment, a tool (such as a hexagonal wrench) is used to engage the hexagonal hole on the top of the docking joint 15. When the docking joint 15 rotates, the worm 14 is driven to rotate. When the worm 14 rotates, the spiral portion on its outer periphery can drive the tooth block 13 of the worm wheel 11 to squeeze, thereby causing the worm wheel 11 to rotate.

[0028] The provision of the rubber friction pad can increase the friction between the joint 15 and the housing 3 , thereby preventing the worm 14 from rotating on its own.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
