The clamp includes a base plate, a fixed seat fixedly mounted at the center of the upper surface of the base plate, end plates fixedly connected to the front and rear ends of the base plate, and movable plates connected to the front and rear ends of the fixed seat via telescopic mechanisms. Two clamping blocks are fixedly connected to the side of the movable plate away from the fixed seat. Soft blocks are fixedly connected to the front and rear ends of the upper surface of the base plate, with the soft blocks positioned between the two clamping blocks. Limiting posts are inserted into the front and rear ends of the two side surfaces of the base plate via elastic mechanisms. This invention enables movement of the bearing outer ring, facilitating the clamping process.

Description

Technical Field

[0001] This invention relates to the field of clamps, and more particularly to a special clamp for clamping and installing the outer ring of a deep groove ball bearing. Background Technology

[0002] Bearings are crucial components in mechanical equipment. Their primary function is to support rotating parts, reduce friction and wear, and ensure the smooth and efficient operation of the equipment. They not only improve the operating efficiency and stability of the equipment but also reduce maintenance costs and failure rates. Therefore, when designing and manufacturing mechanical equipment, damage during the bearing clamping and installation process must be fully considered to ensure the overall performance and reliability of the equipment.

[0003] During the manufacturing and use of deep groove ball bearings, the outer ring needs to be transported between different production stages and locations. To prevent surface damage and dimensional changes in the outer ring due to collisions and friction during transportation, which could affect the bearing's assembly accuracy and service life, specialized fixtures are required to secure and transport the outer ring.

[0004] Existing fixtures often present several problems. For example, while rigid fixtures can secure the outer ring, they can easily cause localized stress concentration, leading to damage. Some general-purpose fixtures cannot tightly fit outer rings of different sizes, resulting in displacement during transport. Some fixtures lack shock absorption and cannot withstand the bumps and vibrations during transport. Some complex fixtures are cumbersome to operate, requiring considerable time for clamping and disassembling workpieces, reducing work efficiency, and are also difficult to maintain and repair, as internal components may be difficult to disassemble and replace. Currently, there is no simple and stable fixture that can effectively prevent damage during the clamping and installation of deep groove ball bearing outer rings. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the prior art by providing a special clamp for gripping and installing the outer ring of a deep groove ball bearing.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a special clamp for clamping and installing the outer ring of a deep groove ball bearing, comprising a base plate, a fixed seat fixedly installed at the middle of the upper surface of the base plate, end plates fixedly connected to the front and rear ends of the base plate, and movable plates connected to the front and rear ends of the fixed seat via telescopic mechanisms, with two clamping blocks fixedly connected to the side of the movable plate away from the fixed seat, and soft blocks fixedly connected to the front and rear ends of the upper surface of the base plate, with the soft blocks located between the two clamping blocks, and limit posts inserted into the front and rear ends of both sides of the base plate via elastic mechanisms, with a movable block connected to the end face of the limit post away from the base plate via a reset mechanism;

[0007] The upper edge of the outer ring of the bearing is clamped and fixed by the clamping block and the end plate, and the moving block abuts against the inner wall of the ring channel.

[0008] Preferably, the telescopic mechanism includes a telescopic cylinder fixedly embedded on the outer surface of the fixed seat, the telescopic end of the telescopic cylinder being fixedly connected to the outer surface of the movable plate, and guide rods being slidably inserted on the outer surface of the fixed seat and on both sides near the telescopic cylinder, with one end of the guide rod being fixedly connected to the outer surface of the movable plate.

[0009] Preferably, the elastic mechanism includes a square hole formed on the inner side of the base plate, one end of the limiting post is inserted into the side of the base plate and extends into the square hole, and a sliding plate is fixedly connected to one end of the limiting post. The sliding plate slides into the inner side of the square hole, and a compression spring is provided on the inner side of the square hole. The compression spring is located on the side of the sliding plate away from the limiting post.

[0010] Preferably, the lower surface of the square hole is provided with a sliding opening, and a lever is fixedly connected to the lower side of the sliding plate, the lever passing through the inner side of the sliding opening.

[0011] Preferably, the lower surface of the base plate is fixedly connected to two fixing sleeves, and a pull plate slides through the inner side of each fixing sleeve. A pull block is fixedly connected to the close end of the two pull plates, and a concave strip is fixedly connected to the far end of the two pull plates. The two ends of the concave strip cross the inner side of the sliding opening.

[0012] Preferably, the reset mechanism includes a convex groove formed on the end face of the limiting post, a convex block slidably inserted into the inner side of the convex groove, one end of the convex block being fixedly connected to the surface of the movable block, a fixing rod being fixedly connected between the front and rear inner walls of the convex groove, and two reset springs being sleeved on the outer surface of the fixing rod, the two reset springs being located on the front and rear surfaces of the convex block respectively.

[0013] Preferably, the movable block has a guide surface at one end near the base plate and a guide edge at the other end.

[0014] Preferably, a connecting plate is fixedly connected to the middle of the upper surface of the fixing base, and a mounting part is fixedly connected to the upper end of the connecting plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this invention, after the outer ring of the bearing on the front and rear conveyor lines moves towards the base plate, the outer ring of the bearing is fitted onto the outer side of the end of the base plate. Then the base plate is moved upward, and the telescopic cylinder is controlled to extend, so that the moving plate moves. The clamping block cooperates with the end plate to clamp and fix the upper part of the outer ring of the bearing. Then, as the robotic arm drives the connecting plate to move, the outer ring of the bearing moves, and the clamping process is convenient.

[0017] 2. During the clamping process, the inner wall of the bearing outer ring will come into contact with the soft block, thus avoiding damage to the bearing outer ring caused by bumps and vibrations during clamping.

[0018] 3. Before the clamping block clamps, when the base plate moves upward, the moving block slides to the inner wall of the ring channel. During this process, the convex block slides back and forth along the inner side of the convex groove, squeezing the return spring in front or behind. In addition, due to the gravity of the outer ring of the bearing, the moving block and the limiting post will be squeezed to move towards the side of the base plate. The sliding plate will slide along the inner side of the square hole, squeezing the compression spring. This part of the design can help the outer ring of the bearing stabilize quickly and avoid the problem of long-term shaking caused by the inner wall of the outer ring of the bearing and the surface of the soft block being in point contact.

[0027] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0028] like Figures 1-7 The present invention relates to a special clamp for clamping and installing the outer ring of a deep groove ball bearing, comprising a base plate 1, a fixed seat 2 fixedly installed at the middle of the upper surface of the base plate 1, end plates 7 fixedly connected to the front and rear ends of the base plate 1, movable plates 5 connected to the front and rear ends of the fixed seat 2 via telescopic mechanisms, two clamping blocks 6 fixedly connected to the side of the movable plate 5 away from the fixed seat 2, soft blocks 8 fixedly connected to the front and rear ends of the upper surface of the base plate 1, and the soft blocks 8 being located between the two clamping blocks 6, and limit posts 9 inserted into the front and rear ends of the two side surfaces of the base plate 1 via elastic mechanisms, and movable blocks 19 connected to the end face of the limit posts 9 away from the base plate 1 via a reset mechanism;

[0029] Upon completion of positioning, the status is as follows: Figure 6 , Figure 7 As shown, the upper edge of the outer ring 28 of the bearing is clamped and fixed by the clamping block 6 and the end plate 7, and the moving block 19 abuts against the inner wall of the ring channel 29.

[0030] like Figure 1 As shown, the telescopic mechanism includes a telescopic cylinder 3 fixedly embedded in the outer surface of the fixed base 2. The telescopic end of the telescopic cylinder 3 is fixedly connected to the outer surface of the movable plate 5. Guide rods 4 are slidably inserted into the outer surface of the fixed base 2 on both sides near the telescopic cylinder 3, and one end of the guide rod 4 is fixedly connected to the outer surface of the movable plate 5. By controlling the extension and retraction of the telescopic cylinder 3, the movable plate 5 moves. During this process, the guide rods 4 will slide back and forth along the fixed base 2, improving the stability of the movable plate 5 during movement.

[0031] like Figure 4 As shown, the elastic mechanism includes a square hole 10 formed inside the base plate 1. One end of a limiting post 9 is inserted into the side of the base plate 1 and extends into the square hole 10. A sliding plate 12 is fixedly connected to one end of the limiting post 9. The sliding plate 12 slides into the inside of the square hole 10. A compression spring 11 is provided inside the square hole 10, located on the side of the sliding plate 12 away from the limiting post 9. When the limiting post 9 is pushed, the sliding plate 12 will slide along the inside of the square hole 10. When the limiting post 9 is no longer pushed, it will return to its original position under the elastic force of the compression spring 11.

[0032] like Figure 2 , Figure 4As shown, a sliding opening 14 is provided on the lower surface of the square hole 10. A lever 13 is fixedly connected to the lower side of the sliding plate 12, and the lever 13 passes through the inner side of the sliding opening 14. By moving the lever 13, the sliding plate 12 can be moved. Two fixed sleeves 15 are fixedly connected to the lower surface of the base plate 1. A pull plate 16 slides through the inner side of each fixed sleeve 15. Pull blocks 18 are fixedly connected to the close ends of the two pull plates 16, and concave strips 17 are fixedly connected to the far ends of the two pull plates 16. The two ends of the concave strips 17 cross the inner side of the sliding opening 14. After the concave strip 17 moves away from the slide 14, the two side plates 13 are brought closer to each other, and then the concave strip 17 is reset. The concave strip 17 locks the two side plates 13 in place. At this time, the limiting post 9 will be retracted into the inner side of the base plate 1. This state is suitable for clamping the outer ring 28 of a heavier bearing. Because of the large weight, it is not easy to shake, and this part of the mechanism does not need to be used for auxiliary stabilization.

[0033] like Figure 6 , Figure 7 As shown, the reset mechanism includes a convex groove 22 formed on the end face of the limiting post 9. A convex block 21 is slidably inserted into the inner side of the convex groove 22. One end of the convex block 21 is fixedly connected to the surface of the moving block 19. A fixing rod 23 is fixedly connected between the front and rear inner walls of the convex groove 22. Two reset springs 24 are sleeved on the outer surface of the fixing rod 23. The two reset springs 24 are located on the front and rear surfaces of the convex block 21, respectively. The two reset springs 24 are used to balance the position of the convex block 21, ensuring that the convex block 21 can be located in the middle position inside the convex groove 22 when the moving block 19 is not pushed.

[0034] The movable block 19 has a guide surface 20 at one end near the base plate 1, and a guide edge 25 at the other end. The guide surface 20 plays an auxiliary role when the limiting post 9 is retracted into the base plate 1, preventing the movable block 19 from hitting the surface of the base plate 1 when it is not in the reset state.

[0035] like Figure 1 , Figure 6 As shown, a connecting plate 26 is fixedly connected to the middle of the upper surface of the fixed base 2, and a mounting part 27 is fixedly connected to the upper end of the connecting plate 26. The mounting part 27 is used to connect with the robotic arm to control the movement of the entire fixture.

[0036] The outer ring 28 of the bearing on the front and rear conveyor lines moves closer to the base plate 1. After the outer ring 28 of the bearing is fitted onto the outer side of the end of the base plate 1, the base plate 1 moves upward. Then, the telescopic cylinder 3 is extended to move the moving plate 5. The clamping block 6 cooperates with the end plate 7 to clamp and fix the upper part of the outer ring 28 of the bearing. Then, as the robotic arm drives the connecting plate 26 to move, the outer ring 28 of the bearing moves. The clamping process is convenient.

[0037] During the clamping process, the inner wall of the bearing outer ring 28 will come into contact with the soft block 8, avoiding damage to the bearing outer ring 28 caused by bumps and vibrations during clamping.

[0038] Before the clamping block 6 clamps, when the base plate 1 moves upward, the moving block 19 slides to the inner wall of the ring channel 29. During this process, the convex block 21 slides back and forth along the inner side of the convex groove 22, squeezing the return spring 24 in front or behind. In addition, due to the gravity of the bearing outer ring 28, the moving block 19 and the limiting post 9 will be squeezed to move towards the side of the base plate 1. The sliding plate 12 will slide along the inner side of the square hole 10, squeezing the compression spring 11. This part of the design can help the bearing outer ring 28 stabilize quickly and avoid the problem of long-term shaking caused by the inner wall of the bearing outer ring 28 and the surface of the soft block 8 making point contact.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention.
