Description

Technical Field

[0001] The utility model relates to the technical field of bearing retainers, in particular to a clamp for processing bearing retainers. Background Art

[0002] Cage (i.e. bearing cage, also known as bearing retainer) refers to a bearing part that partially wraps all or part of the rolling elements and moves with them, isolating the rolling elements, and usually guiding the rolling elements and keeping them in the bearing. When the rolling bearing is working, especially when the load is complex and the bearing rotates at high speed, the cage is subject to great centrifugal force, impact and vibration, and there is great sliding friction between the cage and the rolling elements, which generates a lot of heat. The combined effect of force and heat can lead to cage failure, and in severe cases, it can cause the cage to burn and break.

[0003] After searching, Chinese patent application No. 202121221262.2 discloses a fixture for processing a retaining frame. The patent relates to a fixture for processing a retaining frame, including a base plate, a mounting plate a is fixedly provided at one end of the top of the base plate, and a mounting plate b is fixedly provided at the other end of the top of the base plate. An end clamping assembly driven by a driver is movably installed at the center of the mounting plate a, and a connecting column is fixedly installed at the center of the inner wall of the mounting plate b, and a connecting block is fixedly installed at the end of the connecting column, and a supporting spring is fixedly installed on the four side walls of the connecting block. An internal supporting ring is fixedly installed at the end of the supporting spring, and a limiting arc strip integrally formed with the internal supporting ring is provided on one side of the mounting plate; when the patent is used, one end of the retaining frame is sleeved on the outside of the internal supporting ring, and the retaining frame is clamped under the action of the supporting spring, and the driver drives the sliding plate to move so that the end clamping assembly contacts the other end of the retaining frame, thereby clamping and fixing the retaining frame.

[0004] Although the above patent can sleeve one end of the retaining frame on the outside of the internal support ring, clamp the retaining frame under the action of the support spring, and the driver drives the sliding plate to move so that the end clamping assembly contacts the other end of the retaining frame to clamp and fix the retaining frame, but in actual use, when the patent clamps the retaining frame, the end clamping ring covers the surface of the retaining frame, and the covered part of the retaining frame cannot be processed at this time, so it is necessary to loosen the clamp, turn over the retaining frame, and re-clamp it to expose the covered surface. This operation step is relatively cumbersome, time-consuming and labor-intensive, and is not conducive to daily use by staff.

[0005] Therefore, it is necessary to modify the clamp used for processing the retaining frame in the above-mentioned patent to effectively prevent the end clamping ring from covering the surface of the retaining frame when the retaining frame is clamped. At this time, the covered part of the retaining frame cannot be processed, so it is necessary to loosen the clamp, turn the retaining frame over, and re-clamp it to expose the covered surface. This operation step is cumbersome, time-consuming and labor-intensive. Utility Model Content

It solves the problem that when the retainer is clamped, the end clamping ring covers the surface of the retainer, and the covered part of the retainer cannot be processed at this time, so it is necessary to loosen the clamp, turn over the retainer, and re-clamp it to expose the covered surface. This operation step is cumbersome, time-consuming and labor-intensive.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 4 As shown, the utility model provides a bearing retainer processing fixture, including a base 1, a movable groove 2 is opened on the top of the base 1, and a bidirectional threaded rod 3 is rotatably connected inside the movable groove 2. One end of the bidirectional threaded rod 3 extends to the outside of the base 1 and is fixedly connected to a servo motor 4, and the servo motor 4 is fixedly connected to the base 1, and a thread block 5 is symmetrically threaded on the surface of the bidirectional threaded rod 3. A movable block 6 is fixedly connected to the top of the thread block 5, and a mounting member 7 is fixedly connected to the top of the movable block 6. A rotating groove 8 is opened inside the mounting member 7, and a rotating member 9 is rotatably connected inside the rotating groove 8. A fixture 10 is fixedly connected to the surface of the rotating member 9, and a support block 11 is fixedly connected to the back of the top of the base 1. A screw rod 12 is threaded on the surface of the support block 11, and a movable frame 13 is rotatably connected to the other end of the screw rod 12, and the movable frame 13 is slidably connected to the base 1, and a rotating shaft 14 is rotatably connected to the top of the movable frame 13, and the rotating shaft 14 is used in conjunction with the fixture 10.

[0023] refer to Figure 1 and Figure 2 A slide groove 15 is symmetrically provided on the top of the base 1 about the screw rod 12 , and a slider 16 is symmetrically fixedly connected to the bottom of the moving frame 13 , and the slider 16 is slidably connected to the slide groove 15 .

[0024] As a technical optimization solution of the present invention, by setting the slide groove 15 and the slider 16, the movement state of the moving frame 13 can be restricted so that it can only move linearly to prevent it from tilting.

[0025] refer to Figure 1 , Figure 2 and Figure 3 One end of the rotating shaft 14 passes through the moving frame 13 and is fixedly connected to a rotating motor 17 , and the rotating motor 17 is fixedly connected to the moving frame 13 .

[0026] As a technical optimization solution of the present invention, by providing a rotating motor 17 , the rotating shaft 14 can be driven, thereby facilitating the control of the rotation angle of the rotating shaft 14 .

[0027] refer to Figure 1 , Figure 2 and Figure 3 The surface of the rotating shaft 14 is covered with an anti-slip sleeve 18 , and the anti-slip sleeve 18 is used in conjunction with the clamp 10 .

[0028] As a technical optimization solution of the present invention, the anti-slip sleeve 18 is provided to increase the friction force on the surface of the rotating shaft 14 and protect the rotating shaft 14 .

[0029] refer to Figure 1 and Figure 2 , the diameter of the clamp 10 is greater than the width of the moving block 6.

[0030] As a technical optimization solution of the present invention, by setting the diameter of the clamp 10 to be larger than the width of the moving block 6 , the rotating shaft 14 is prevented from contacting the moving block 6 , ensuring that the rotating shaft 14 is fitted with the clamp 10 first.

[0031] refer to Figure 1 and Figure 2 One end of the screw rod 12 away from the moving frame 13 is fixedly connected to a crank 19.

[0032] As a technical optimization solution of the utility model, the setting of the crank 19 makes it convenient for the staff to operate and control the position of the moving frame 13.

[0033] The working principle and usage process of the utility model are as follows: when the staff uses the clamp to clamp the bearing retainer, first connect the device to an external power supply, then place the bearing retainer between the two clamps 10, and then start the servo motor 4 to drive the bidirectional threaded rod 3 to rotate, so that the two threaded blocks 5 can move relative to each other, so that the two clamps 10 can clamp the bearing retainer, and then rotate the crank 19 to move the moving frame 13 to fit the surface of the clamp 10. At this time, the clamp 10 can be braked by the anti-slip sleeve 18 to prevent the bearing retainer from rotating during processing. When it is necessary to rotate the bearing retainer, it is only necessary to start the rotating motor 17 to drive the rotating shaft 14 to rotate, and then drive the clamp 10 and the rotating part 9 to rotate in the rotating groove 8, so that the bearing retainer can rotate, so that the surface of the bearing retainer can be completely exposed to the outside world when clamping it, and the retainer can be rotated, which is convenient for the staff to process it.
