Description

Technical Field

[0001] This utility model is specifically a punching and positioning device for bearing cages, belonging to the field of bearing cage processing technology. Background Technology

[0002] A cage (also known as a bearing retainer) is a bearing component that partially encloses all or part of the rolling elements and moves with them. It is used to isolate the rolling elements and usually also guides and holds the rolling elements within the bearing. Chinese Patent Publication No. CN218503112U discloses a punching device for a self-aligning bearing cage, which includes a housing. A connecting plate is fixedly connected to the upper surface of the housing, and a punching mechanism is provided on the lower surface of the connecting plate. This punching device for a self-aligning bearing cage, by setting a rotating shaft, a half gear, a toothed plate, and an arc-shaped clamping block, allows one rotating shaft to drive the other rotating shaft to reverse through the meshing of two transmission wheels. Both rotating shafts are driven by the meshing of the half gear and the toothed plate, causing the two toothed plates to move closer to each other using the elastic force of a first spring. This allows the two connecting rods to drive the arc-shaped clamping block to move closer to each other to clamp the cage. Thus, this device can perform a fast clamping operation on the cage, making the clamping process of the cage relatively quick, thereby avoiding affecting the punching efficiency of the cage. Since the cage contains multiple holes, in the existing technology, after the cage is fixed, only one hole can be punched at a time. If subsequent holes need to be processed, the cage must be disassembled, adjusted to the corresponding processing position, and then fixed again before the next punching is performed. The process is relatively cumbersome, resulting in low punching efficiency and reduced convenience. Summary of the Invention

[0003] The purpose of this utility model is to provide a punching and positioning device for bearing cages to solve the above-mentioned problems. This solves the problem that in the prior art, when processing subsequent holes, the cage must first be disassembled, adjusted to the corresponding processing position, and then re-fixed before the next punching is performed, which is relatively cumbersome in terms of operation.

[0004] This utility model is achieved through the following technical solution: a punching and positioning device for a bearing cage, comprising a worktable, support columns fixed at the four corners of the bottom of the worktable, a mounting frame fixed at the top center of the worktable, a hydraulic cylinder fixed through the top center of the mounting frame, a connecting plate fixed at the end of the output shaft of the hydraulic cylinder, a punch connected to the bottom center of the connecting plate, an adjustment mechanism provided at the top of the worktable, and a fixing mechanism provided inside the adjustment mechanism.

[0005] Preferably, the adjustment mechanism includes a mounting plate fixed to the top of the workbench, a housing rotatably passing through the opposite sides of the two mounting plates via a bearing ring, fixing holes evenly provided on the outer side wall of the housing, a rotating ring fixed to one side of the housing, a fixing plate fixed to the middle of one side of the two mounting plates, a sliding insert rod passing through the middle of one side of the fixing plate, a pull plate fixed to one end of the insert rod, and a return spring fixed to one side of the pull plate.

[0006] Preferably, the outer wall of the rotating ring is provided with anti-slip texture to prevent slippage, and the fixing hole is located between the two mounting plates to facilitate the alignment of the insertion rod with the fixing hole.

[0007] Preferably, one end of the return spring is fixed to one side of the fixing plate, and the return spring is sleeved on the outside of the insertion rod to facilitate the insertion rod to return to its original position.

[0008] Preferably, the fixing mechanism includes a groove formed on one side of the outer shell, a slide rod fixed inside the groove, a connecting shaft symmetrically sliding on the outside of the slide rod, a clamping block fixed at one end of the connecting shaft, a rotating disk rotating inside the outer shell, and a vortex groove symmetrically formed on one side of the rotating disk.

[0009] Preferably, the fixing mechanism further includes a rotating shaft fixed to the middle of the other side of the rotating disk, a knob fixed to one end of the rotating shaft, and a fastening bolt threaded through one side of the knob.

[0010] Preferably, the rotating shaft passes through the middle of the other side of the outer casing, and the rotating shaft is rotatably connected to the outer casing, so that when the rotating shaft rotates, it drives the rotating disk to rotate.

[0011] Preferably, the connecting shaft is located inside the vortex groove and the sliding groove. When the vortex groove rotates, the connecting shaft gradually moves away from the center of the rotating disk, while the connecting shaft moves inside the sliding groove. A circular hole is provided through one side of the clamping block.

[0012] This utility model provides a punching and positioning device for bearing cages, which has the following advantages: 1. This application, through the setting of the adjustment mechanism, allows the pull plate to be pulled when the punching position needs to be changed, thereby moving the insert rod out of the fixing hole and releasing the fixing of the outer shell. Then, the rotating ring is rotated, causing the outer shell to deflect so that the next fixing hole is aligned with the insert rod. The pull plate is then loosened, and the insert rod is repositioned into the fixing hole by the reset spring, fixing the outer shell. This changes the punching position, avoiding the need to disassemble the cage and reposition it, thus improving punching efficiency and the convenience of the device.

[0013] 2. This application, through the setting of a fixing mechanism, involves placing the retainer on the clamping block, rotating the knob to drive the rotating shaft to rotate, causing the rotating disk to rotate, which in turn causes the vortex groove to rotate, thereby causing the connecting shaft to gradually move away from the center of the rotating disk, and thus causing the connecting shaft to move outside the slide rod, thereby causing the clamping blocks to move away from each other, and tightening and fixing the inner side of the retainer, ensuring the stability of the fixation, preventing the retainer from loosening during punching, and improving the processing quality.

[0016] This utility model provides a punching and positioning device for a bearing cage. Example 1:

[0017] A punching and positioning device for a bearing cage includes a worktable 1, support columns 2 fixed at the four corners of the bottom of the worktable 1, a mounting bracket 3 fixed at the top center of the worktable 1, a hydraulic cylinder 301 fixed through the top center of the mounting bracket 3, a connecting plate 302 fixed at the end of the output shaft of the hydraulic cylinder 301, a punch 303 connected to the bottom center of the connecting plate 302, and an adjustment mechanism 4 provided on the top of the worktable 1.

[0018] Please refer to it again. Figure 2The adjusting mechanism 4 includes a mounting plate 401 fixed to the top of the workbench 1. A housing 402 is rotatably connected between the opposite sides of the two mounting plates 401 via a bearing ring. Fixing holes 403 are evenly distributed on the outer side wall of the housing 402. A rotating ring 404 is fixed to one side edge of the housing 402. A fixing plate 405 is fixed to the middle of one side of the two mounting plates 401. A sliding rod 406 is slidably connected to the middle of one side of the fixing plate 405. A pull plate 407 is fixed to one end of the rod 406. A return spring 408 is fixed to one side of the pull plate 407. The outer side wall of the rotating ring 404 is provided with anti-slip texture. The fixing holes 403 are located between the two mounting plates 401. One end of the return spring 408 is fixed to the fixing plate. On one side of 405, and the return spring 408 is sleeved on the outside of the insertion rod 406; by adjusting the mechanism 4, when the punching position needs to be changed, pull the pull plate 407 to move the insertion rod 406, so that the insertion rod 406 moves out of the fixing hole 403, releasing the fixing of the outer shell 402. Then, rotate the rotating ring 404 to drive the outer shell 402 to deflect, so that the next fixing hole 403 is aligned with the insertion rod 406. Loosen the pull plate 407, and through the reset of the return spring 408, make the insertion rod 406 embedded in the fixing hole 403, fixing the outer shell 402, thereby changing the punching position, avoiding the need to disassemble the cage and change its position to re-fix it, improving punching efficiency and the convenience of the device. Example 2:

[0019] Please refer to it again. Figure 3 , Figure 4 and Figure 5The adjusting mechanism 4 has a fixing mechanism 5 inside. The fixing mechanism 5 includes a slide groove 501 on one side of the outer casing 402. A slide rod 502 is fixed inside the slide groove 501. A connecting shaft 503 slides symmetrically on the outside of the slide rod 502. A clamping block 504 is fixed to one end of the connecting shaft 503. A rotating disk 505 rotates inside the outer casing 402. A vortex groove 506 is symmetrically opened on one side of the rotating disk 505. The fixing mechanism 5 also includes a rotating shaft 507 fixed to the middle of the other side of the rotating disk 505. A knob 508 is fixed to one end of the rotating shaft 507. A fastening bolt 509 is threaded through one side of the knob 508. The rotating shaft 507 passes through the middle of the other side of the outer casing 402, and the rotating shaft 507... 7 is rotatably connected to the outer casing 402; the connecting shaft 503 is located inside the vortex groove 506 and inside the slide groove 501, and a circular hole is provided through one side of the clamping block 504; by setting the fixing mechanism 5, by sleeve the retainer on the clamping block 504, rotating the knob 508 drives the rotating shaft 507 to rotate, causing the rotating disk 505 to rotate, and then causing the vortex groove 506 to rotate, so that the connecting shaft 503 gradually moves away from the center of the rotating disk 505, and then the connecting shaft 503 moves outside the slide rod 502, so that the clamping blocks 504 move away from each other, and the inner side of the retainer is tightened and fixed to ensure the stability of the fixation, prevent the retainer from loosening during punching, and improve the processing quality.

[0020] When using this utility model: Working principle: The cage is fitted onto the clamping block 504. Rotating the knob 508 drives the rotating shaft 507 to rotate, causing the rotating disk 505 to rotate, which in turn causes the volute groove 506 to rotate. This causes the connecting shaft 503 to gradually move away from the center of the rotating disk 505, thus moving the connecting shaft 503 outside the slide rod 502. This causes the clamping blocks 504 to move away from each other, tightening and fixing the inner side of the cage. Tightening the fastening bolt 509 secures the knob 508, ensuring a stable connection. The hydraulic cylinder 301 is activated, moving the connecting plate 302, causing the punch 303 to punch the cage. After punching, the hydraulic cylinder 301 drives the punch 303 to reset. When it is necessary to change the punching position, the pull plate 407 is pulled to move the insertion rod 406, so that the insertion rod 406 moves out of the fixing hole 403, releasing the fixing of the outer shell 402. Then, the rotating ring 404 is rotated, causing the outer shell 402 to deflect, so that the next fixing hole 403 is aligned with the insertion rod 406. The pull plate 407 is loosened, and the insertion rod 406 is embedded in the fixing hole 403 by the reset spring 408, fixing the outer shell 402, thereby changing the punching position and punching again.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
