Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a clamping fixture for preventing edge chipping when cutting bearing plates. Background Technology

[0002] Bearing plate is a type of sheet material used to manufacture bearing components. It is an important basic material in the bearing production chain. Because bearings need to withstand complex working conditions of alternating loads and friction and wear in mechanical transmission, the requirements for material performance are stringent. Therefore, bearing plate has special standards in terms of material selection, performance indicators, and processing precision. Bearing plate cutting refers to the process of cutting and processing the sheet material raw materials used to manufacture bearings. Its purpose is to cut the bearing plate into blanks of specific sizes and shapes according to production needs, so as to provide basic materials for subsequent bearing component processing.

[0003] To prevent edge breakage, peeling, and excessive burrs caused by uneven stress, material brittleness, and improper cutting methods during the cutting process of bearing plates, anti-chipping clamps are used during the cutting process. Existing anti-chipping clamps reduce the damage to the plate by clamping horizontally on one side during operation. However, when dealing with different plates, uneven clamping force can easily cause the plate to warp, which can actually aggravate chipping. They do not have a pressing effect on the cut edge and are not very effective in preventing chipping. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a bearing plate cutting anti-chipping clamp, which aims to improve the problem of uneven clamping force and inability to press the cutting edge vertically in the prior art.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a bearing plate cutting anti-chipping clamp, including a pressing rod, a suction cup fixedly connected to the bottom end of the pressing rod, a vent buckle fixedly connected to the outer wall of the suction cup near the edge, a limiting ring slidably connected to the upper middle part of the outer wall of the pressing rod, a support rod one fixedly connected to the outer wall of the limiting ring, a support rod two fixedly connected to the top end of the pressing rod, a fixing ring one fixedly connected to the top end of the support rod two, a rotating rod one rotatably connected to the inner wall of the fixing ring one, and a gear inner shaft fixedly connected to the outer wall of the rotating rod one. A gear is fixedly connected to the outer wall of the support rod. A fixed frame is engaged with the front and rear sides of the gear. A gear is meshed with the outer wall of the gear. A limit rod is fixedly connected to the middle of the inner wall of the fixed frame. A fixed ring is fixedly connected to the top of the support rod. A rotating rod is rotatably connected to the inner wall of the fixed ring. A telescopic plate is fixedly connected to the bottom of the support rod. A fixed plate is slidably connected to the outer wall of the telescopic plate. A bearing plate is fixedly connected to the opposite side of the multiple fixed plates. A clamping mechanism is fixedly connected to the bottom of the bearing plate. The clamping mechanism is used to horizontally clamp the bearing plate.

[0006] As a further description of the above technical solution: The clamping mechanism includes a second slider, the top of which is fixedly connected to the bottom of a support plate. A sliding column is fixedly connected to the inner wall of the second slider, and a guide rail is slidably connected to the inner wall of the sliding column. Fixed blocks are fixedly connected to the left and right ends of the guide rail. A first slider is slidably connected to the outer wall of the guide rail. A gear rack is fixedly connected to the outer wall of the first slider. A third slider is fixedly connected to the outer wall of the first gear. A gear rack is meshed with the outer wall of the first gear. A second gear is meshed with the outer wall of the third gear. Limiting circular plates are fixedly connected to the top and bottom of the third gear. A transmission block is fixedly connected to the bottom of the first slider, and a pneumatic regulating pump is fixedly connected to the outer wall of the transmission block.

[0007] As a further description of the above technical solution: Limiting holes are provided on the front and rear sides of the telescopic plate, and a locking device is slidably connected to the inner wall of the limiting hole.

[0008] As a further description of the above technical solution: A clamping plate is fixedly connected to the lower middle part of the outer wall of the bearing plate, and a clamping sponge is fixedly connected to the right side of the clamping plate.

[0009] As a further description of the above technical solution: A tabletop is fixedly connected to the lower end of the fixing block, and a sliding groove is provided on the top front side of the tabletop near the edge.

[0010] As a further description of the above technical solution: The bottom of the tabletop is fixedly connected to multiple support blocks, and the bottom of each support block is fixedly connected to a telescopic column.

[0011] As a further description of the above technical solution: The telescopic column has multiple gear slots on its outer wall, and the inner wall of the gear slots is engaged with a shift block. The bottom end of the shift block is rotatably connected to a support rod.

[0012] As a further description of the above technical solution: The telescopic column is slidably connected to a storage tube on its outer wall, and a table leg is fixedly connected to the bottom of the storage tube.

[0013] This utility model has the following beneficial effects: 1. In this utility model, rotating the rotating rod two drives the gear two to rotate via the inner shaft of the gear. Since gear one and gear two are meshed and are in the fixed frame, rotating the rotating rod two will cause gear two and gear one to move up and down, thereby driving the support rod two and the connected pressing rod and suction cup to move up and down. The pressing rod and suction cup are horizontally limited by the limiting ring, and finally move downward to clamp the cutting edge of the plate, so as to reduce the cutting stress and reduce shock to prevent edge chipping.

[0014] 2. In this utility model, the clamping mechanism provides tension through a pneumatic regulating pump, which drives the transmission block to move centripetally through the sliding groove, causing the slider one, the bearing plate and the gear rack one to move to the left. The gear rack one, through the engagement of the limiting circular plate, drives the gear rack two to move to the right, causing the slider two to move to the right. The bearing plates at both ends then drive the clamping plate and the clamping sponge to clamp the plate centripetally. The clamping force can be adjusted by the pneumatic regulating pump to avoid excessive force damaging the material or insufficient force causing edge chipping. Attached Figure Description

[0018] Please see the appendix Figure 1 Appendix Figure 5 and attached Figure 6 This utility model provides an embodiment of a bearing plate cutting anti-chipping clamp, comprising a pressing rod 1, a suction cup 3 fixedly connected to the bottom end of the pressing rod 1, a vent buckle 4 fixedly connected to the outer wall of the suction cup 3 near the edge, a limiting ring 5 slidably connected to the upper middle part of the outer wall of the pressing rod 1, a support rod 6 fixedly connected to the outer wall of the limiting ring 5, a support rod 7 fixedly connected to the top end of the pressing rod 1, a fixing ring 8 fixedly connected to the top end of the support rod 7, a rotating rod 9 rotatably connected to the inner wall of the fixing ring 8, a gear inner shaft 10 fixedly connected to the outer wall of the rotating rod 9, and a gear 1... 11. Gear 11 is engaged with a fixed frame 12 on both the front and rear sides. Gear 2 14 is engaged with the outer wall of gear 11. A limit rod 13 is fixedly connected to the middle of the inner wall of the fixed frame 12. A fixed ring 2 16 is fixedly connected to the top of support rod 16. A rotating rod 2 15 is rotatably connected to the inner wall of fixed ring 2 16. A telescopic plate 17 is fixedly connected to the bottom of support rod 16. A fixed plate 19 is slidably connected to the outer wall of telescopic plate 17. A bearing plate 21 is fixedly connected to the opposite side of the multiple fixed plates 19. A clamping mechanism 2 is fixedly connected to the bottom of the bearing plate 21. The clamping mechanism 2 is used to horizontally clamp the bearing plate. Specifically, the bottom end of the pressing rod 1 is connected to the suction cup 3, and the air release buckle 4 is used to control the suction and release of the suction cup 3, which facilitates quick and easy picking up and putting down of the board. The limiting ring 5 is fixed to the outer wall of the pressing rod 1 and the connected support rod 6 to enhance the overall stability. The second support rod 7 at the top of the pressing rod 1 is connected to the fixing ring 8. The rotating rod 9 inside drives the gear inner shaft 10 and gear 11 to rotate. The second gear 14 meshes with the gear 11, and the gear 11 engages with the fixing brackets 12 on both sides. With the help of the limiting rod 13, the height of the pressing rod 1 can be adjusted by rotation to adapt to different boards. The telescopic plate 17 at the bottom of the support rod 6 can slide in the fixing plate 19 to realize the telescopic adjustment of the clamping range. The bearing plate 21 is used to support the bottom of the board, and the clamping mechanism 2 at the bottom of the bearing plate 21 clamps the edge of the board from the horizontal direction.

[0019] Please see the appendix Figure 1 and attached Figure 3 The clamping mechanism 2 includes a second slider 207, the top of which is fixedly connected to the bottom of the bearing plate 21. A sliding column 204 is fixedly connected to the inner wall of the second slider 207. A guide rail 205 is slidably connected to the inner wall of the sliding column 204. A fixing block 206 is fixedly connected to both the left and right ends of the guide rail 205. A first slider 203 is slidably connected to the outer wall of the guide rail 205. A gear rack 209 is fixedly connected to the outer wall of the first slider 203. A third slider 208 is fixedly connected to the outer wall of the first gear rack 209. A third gear 210 is meshed with the outer wall of the first gear rack 209. A second gear rack 212 is meshed with the outer wall of the third gear rack 210. A limit plate 211 is fixedly connected to the top and bottom of the third gear rack 210. A transmission block 202 is fixedly connected to the bottom of the first slider 203. A pneumatic regulating pump 201 is fixedly connected to the outer wall of the transmission block 202. Specifically, slider 207 is fixed to the bottom of the bearing plate 21, and the sliding column 204 on its inner wall slides along the guide rail 205. The two ends of the guide rail 205 are fixed by the fixing block 206, which can drive the bearing plate 21 and the overall clamping mechanism 2 to move laterally along the guide rail 205. Slider 1 203 also slides on the guide rail 205. The air pressure regulating pump 201 drives slider 1 203 to move through the transmission block 202. The gear rack 1 209 connected to slider 1 203 slides accordingly. Slider 3 208 assists gear rack 1 209 to slide stably. Gear rack 1 209 meshes with gear rack 3 210, driving gear rack 3 210 to rotate, which in turn drives the meshing gear rack 212 to move in the opposite direction. The limiting circular plates 211 above and below gear rack 3 210 restrict its axial displacement to ensure stable meshing. The reverse sliding of gear rack 1 209 and gear rack 212 can drive the clamping plate 22 to move closer and further away synchronously, realizing the horizontal clamping and loosening of the edge of the plate.

[0020] Please see the appendix Figure 1 and attached Figure 4Limiting holes 18 are provided on the front and rear sides of the telescopic plate 17. A lock 20 is slidably connected to the inner wall of the limiting hole 18. A clamping plate 22 is fixedly connected to the lower middle part of the outer wall of the bearing plate 21. A clamping sponge 23 is fixedly connected to the right side of the clamping plate 22. A table 24 is fixedly connected to the lower end of the fixing block 206. A sliding groove 29 is provided on the top front side of the table 24 near the edge. Specifically, the limiting holes 18 on the front and rear sides of the telescopic plate 17 are slidably connected to the locking device 20. When the telescopic plate 17 slides along the fixed plate 19 to a position that matches the size of the plate, the locking device 20 can be inserted into the corresponding limiting hole 18 to adjust the upper and lower clamping range. The clamping plate 22 on the outer wall of the bearing plate 21 directly contacts the edge of the plate. The clamping sponge 23 on its right side adheres to the surface of the plate through elastic deformation, thereby enhancing the clamping friction and absorbing some vibration during cutting, further reducing the risk of edge chipping. The lower end of the fixed block 206 is connected to the table 24. The sliding groove 29 on the front side of the top of the table 24 allows the air pressure regulating pump 201 to drive the transmission block 202 to move centripetally through the sliding groove 29.

[0021] Please see the appendix Figure 1 and attached Figure 2 The bottom of the tabletop 24 is fixedly connected to multiple support blocks 25, and the bottom of the support blocks 25 is fixedly connected to a telescopic column 26. The outer wall of the telescopic column 26 is provided with multiple gear slots 30, and the inner wall of the gear slots 30 is engaged with a shift block 31. The bottom end of the shift block 31 is rotatably connected to a support rod 32. The outer wall of the telescopic column 26 is slidably connected to a storage tube 27, and the bottom of the storage tube 27 is fixedly connected to a table leg 28. Specifically, the support block 25 at the bottom of the tabletop 24 is connected to the telescopic column 26, which adjusts the overall height of the tabletop 24 by telescopic adjustment. Multiple slots 30 on the outer wall of the telescopic column 26 engage with the shift block 31. The support rod 32 is rotatably connected to the bottom of the shift block 31. The storage tube 27 is slidably connected to the outer wall of the telescopic column 26, which adjusts the height of the device. The table legs 28 at the bottom of the storage tube 27 increase the contact area with the ground, further improving the overall stability of the fixture.

[0022] Working principle: When the clamping device is working normally, rotating the rotating rod 15 drives the gear 14 to rotate through the gear inner shaft 10. Gear 11 meshes with gear 14 in the fixed frame 12. When the gear inner shaft 10 rotates, the rotating rod 15 is rotatably connected to the edge of the gear inner shaft 10. The rotating rod 15 is fixed in the vertical direction. When it rotates, it will drive gear 14 to move up and down, which will also cause gear 11 to move up and down. Similarly, the support rod 7 is rotatably connected to the edge of gear 11 through the rotating rod 9, so the support rod 7 also moves up and down. The pressing rod 1 and the suction cup 3 are horizontally limited by the limiting ring 5 and fixedly connected to the support rod 7. They can move up and down with the support rod 7. Finally, by rotating the rotating rod 15, the pressing rod 1 and the suction cup 3 are driven to move downward to clamp the cutting edge of the plate, reduce cutting stress and dampen vibration, and prevent edge chipping.

[0023] The clamping mechanism 2 is used for horizontal centripetal clamping and fixing of the sheet metal. When the device is working normally, the control air pressure regulating pump 201 provides a stable pulling force, which drives the transmission block 202 to move centripetally through the sliding groove 29. The slider 1 203 is fixedly connected to the transmission block 202 and the gear rack 1 209, which in turn moves the bearing plate 21 and the gear rack 1 209 to the left. The gear rack 1 209 and the gear rack 212 are meshed and connected through the limiting circular plate 211. The gear rack 1 209 moves to the left, which drives the limiting circular plate 211 to rotate clockwise, which in turn drives the gear rack 212 to move to the right, which drives the slider 2 207 to move to the right. The bearing plates 21 at both ends are fixedly connected to the slider 2 207 and the slider 1 203 respectively. Therefore, the bearing plate 21 drives the clamping plate 22 and the clamping sponge 23 to follow the slider 2 207 and the slider 1 203 for centripetal clamping. The magnitude of the centripetal clamping force can be adjusted by the air pressure regulating pump 201 to prevent the force from being too large and damaging the sheet metal, or too small and causing the edge to break.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
