Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing, in particular to a clamping device for processing a retaining frame. Background Art

[0002] A bearing cage refers to a bearing component that partially wraps all or part of the rolling elements and moves with them. It is used to isolate the rolling elements and usually guides the rolling elements and holds them in the bearing. During the production of the bearing cage, a clamping device is required to position the bearing cage to assist in its production.

[0003] After the existing retainer clamping device completes the processing of the retainer, it is usually necessary to loosen the clamping of the retainer, then remove the processed retainer, place the retainer to be processed on the clamping device, and then clamp and position the retainer to be processed. Such a series of replacement steps reduces the clamping efficiency of the clamping device for the retainer. For this reason, the utility model improves a clamping device that can retain the retainer faster. Summary of the Invention

[0004] The disclosed embodiment relates to a clamping device for processing a bearing retainer, which arranges two clamping platforms on a switching shaft so that a driving motor can rotate the switching shaft and the clamping platform, so that the clamping column on the clamping platform can cancel the clamping of the already processed bearing retainer during the rotation process and clamp and position the bearing to be processed, so that workers can remove the processed bearing retainer conveniently while clamping a new bearing retainer for processing.

[0005] According to a first aspect of the present disclosure, a clamping device for machining a retainer is provided, which specifically includes: a support base, wherein a drive motor is fixedly installed inside the support base; a switching shaft is rotatably installed at the center of the top of the support base; the bottom end of the switching shaft is connected to the output shaft of the drive motor; a transmission rack A is fixedly installed on the front side of the top of the support base; a transmission rack B is fixedly installed on the rear side of the top of the support base; two clamping platforms are fixedly installed in a symmetrical arrangement on the top of the switching shaft; a bearing retainer is placed on the top of the clamping platform; and the top of the clamping platform is also provided with guide grooves arranged in a circumferential shape.

[0006] In at least some embodiments,

[0007] A clamping slide is installed in a sliding manner inside the guide slot; the clamping slide is a cylindrical structure, and the clamping slide is located inside the bearing retainer; one end of a spring is embedded in the inner side of the clamping slide; the other end of the spring is embedded in the inner wall of the guide slot.

[0008] In at least some embodiments,

[0009] A self-locking worm gear is rotatably installed inside the clamping platform; a disc-shaped transmission chuck is rotatably installed on the top inner surface of the clamping platform; the top of the transmission chuck is arranged in a circular shape and has an arc-shaped transmission clamping groove; the bottom end of the clamping slide is also slidably installed inside the transmission clamping groove.

[0010] In at least some embodiments,

[0011] A self-locking worm is fixedly installed at the center position of the bottom of the transmission chuck; a follower gear is fixedly installed at the bottom end of the self-locking worm; the self-locking worm is cooperatively connected with the self-locking worm wheel; when the follower gear rotates to the front position of the support base, the follower gear will be meshed and connected with the transmission rack A; when the follower gear rotates to the rear position of the support base, the follower gear will be meshed and connected with the transmission rack B.

[0012] The utility model provides a clamping device for processing a retainer, which has the following beneficial effects:

[0013] Since two clamping platforms are provided in the clamping device, and the two clamping platforms can be driven to rotate by the drive motor and the switching shaft, after the processing of the bearing retainer on one clamping platform is completed, the other clamping platform can be directly switched over, so that the unprocessed bearing retainer on the other clamping platform can be moved to the staff's workstation, so that the staff can quickly process the next bearing retainer, thereby improving the replacement efficiency of the bearing retainer.

[0014] By setting up a transmission rack A and a transmission rack B in the clamping device, and utilizing the cooperation between these two transmission racks and the follower gear, the clamping slide column can be tightened or contracted when the clamping platform rotates on the transmission rack A and the transmission rack B respectively. In this way, after processing a bearing cage, it is only necessary to rotate the clamping platform to cancel the clamping of the processed bearing cage and clamp the unprocessed bearing cage, thereby omitting the replacement step and improving the processing efficiency of the bearing cage.

[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Please refer to Figures 1 to 6 :

[0028] Example 1:

[0029] The utility model proposes a clamping device for processing a retainer, comprising: a support base 1, a drive motor 2 is fixedly installed inside the support base 1; a switching shaft 3 is rotatably installed at the center of the top of the support base 1; the bottom end of the switching shaft 3 is connected to the output shaft of the drive motor 2; a transmission rack A4 is fixedly installed on the front side of the top of the support base 1; a transmission rack B5 is fixedly installed on the rear side of the top of the support base 1; two clamping platforms 6 are symmetrically arranged and fixedly installed on the top of the switching shaft 3; a bearing retainer 7 is placed on the top of the clamping platform 6; and a guide slot 8 is also arranged in a surrounding shape on the top of the clamping platform 6.

[0030] By placing the bearing retainer 7 on the clamping platform 6 currently located on the left, and then starting the drive motor 2, the drive motor 2 rotates counterclockwise with the switching shaft 3 and the two clamping platforms 6. During the rotation process, the corresponding follower gear 15 on the clamping platform 6 where the bearing retainer 7 is placed will engage with the transmission rack A4, so that the follower gear 15 is affected by the transmission rack A4 and rotates clockwise with the corresponding transmission chuck 12. The transmission chuck 12 rotates clockwise and uses the arc structure of the transmission clamping groove 13 to pull the clamping slide 9 outward along the guide slide groove 8, so that the clamping slide 9 moves outward to achieve internal clamping positioning of the bearing retainer 7.

[0031] Example 2, based on Example 1,

[0032] A clamping slide post 9 is slidably mounted inside the guide slot 8; the clamping slide post 9 is a cylindrical structure and is located inside the bearing retainer 7; one end of a spring 10 is embedded inside the clamping slide post 9; the other end of the spring 10 is embedded in the inner wall of the guide slot 8; a self-locking worm gear 11 is rotatably mounted inside the clamping platform 6; a disc-shaped transmission chuck 12 is rotatably mounted on the top end of the clamping platform 6;

[0033] After the bearing retainer 7 on one clamping platform 6 is clamped, another bearing retainer 7 to be processed can be placed on another clamping platform 6 , and then processing of the clamped bearing retainer 7 can be started.

[0034] Example 3, based on Example 2,

[0035] The top of the transmission chuck 12 is arranged in a circular shape and is provided with an arc-shaped transmission clamping groove 13; the bottom end of the clamping slide 9 is also slidably installed inside the transmission clamping groove 13; a self-locking worm 14 is fixedly installed at the center position of the bottom of the transmission chuck 12; a follower gear 15 is fixedly installed at the bottom end of the self-locking worm 14; the self-locking worm 14 is connected with the self-locking worm wheel 11; when the follower gear 15 rotates to the front position of the support base 1, the follower gear 15 will be engaged and connected with the transmission rack A4; when the follower gear 15 rotates to the rear position of the support base 1, the follower gear 15 will be engaged and connected with the transmission rack B5.

[0036] After the processing is completed, the driving motor 2 is started again to continue to rotate counterclockwise with the switching shaft 3 and the two clamping platforms 6. At this time, the follower gear 15 on the clamping platform 6 where the processed bearing holder 7 is placed will mesh with the transmission rack B5, so that the transmission rack B5 and the follower gear 15 cooperate to drive the transmission chuck 12 to rotate counterclockwise, so that the transmission chuck 12 is restored by counterclockwise rotation, so that the transmission clamping groove 13 will not pull the clamping slide 9, so that the clamping slide 9 moves inward along the guide slide groove 8 under the action of the spring 10, so that the clamping slide 9 cancels the clamping positioning of the processed bearing holder 7 by moving inward, which is convenient for the staff to cancel the processed bearing holder 7. At the same time, the follower gear 15 on the clamping platform 6 where the unprocessed bearing holder 7 is placed will mesh with the transmission rack A4 again, thereby repeating the above clamping steps. Such a cycle will not waste time on replacing the bearing holder 7, thereby improving the processing efficiency of the bearing holder 7.

[0037] Working principle:

[0038] First, the bearing holder 7 is placed on the clamping platform 6 currently located on the left, and then the drive motor 2 is started, so that the drive motor 2 rotates counterclockwise with the switching shaft 3 and the two clamping platforms 6. During the rotation process, the corresponding follower gear 15 on the clamping platform 6 where the bearing holder 7 is placed will mesh with the transmission rack A4, so that the follower gear 15 is affected by the transmission rack A4 and the corresponding transmission chuck 12 rotates clockwise, so that the transmission chuck 12 rotates clockwise and uses the arc structure of the transmission clamping groove 13 to pull the clamping slide post 9 outward along the guide slide groove 8, so that the clamping slide post 9 moves outward to realize the clamping positioning of the bearing holder 7 internally. At this time, the bearing holder 7 waiting for processing can also be placed on another clamping platform 6, and then the processing of the clamped bearing holder 7 can be started. After the processing is completed, the drive motor 2 is started again. The gear 15 on the clamping platform 6 where the machined bearing holder 7 is placed is meshed with the transmission rack B5, so that the transmission rack B5 and the follower gear 15 cooperate to rotate the transmission chuck 12 counterclockwise, so that the transmission chuck 12 is restored by counterclockwise rotation, so that the transmission clamping groove 13 will not pull the clamping slide 9, so that the clamping slide 9 moves inward along the guide slide groove 8 under the action of the spring 10, so that the clamping slide 9 cancels the clamping positioning of the machined bearing holder 7 by moving inward, which is convenient for the staff to cancel the machined bearing holder 7. At the same time, the follower gear 15 on the clamping platform 6 where the unmachined bearing holder 7 is placed will mesh with the transmission rack A4 again, thereby repeating the above clamping steps. Such a cycle will not waste time on replacing the bearing holder 7, thereby improving the processing efficiency of the bearing holder 7.
