[0002] Bearings are vital parts in mechanical equipment. Their main function is to support rotating parts, reduce friction and wear, and ensure that mechanical equipment can run smoothly and efficiently. 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, the damage during the clamping and installation of the bearing 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 links and locations.

[0004] In the existing inventions, common clamps have some problems. For example, although rigid clamps can fix the outer ring, they are prone to local stress concentration on the outer ring, causing damage; some general clamps cannot fit the outer rings of different sizes tightly, resulting in displacement during transportation; some clamps do not have shock-absorbing and buffering functions and cannot cope with the bumps and vibrations during transportation; some complex clamps are cumbersome to operate, requiring a lot of time to clamp and disassemble workpieces, reducing work efficiency, and are difficult to repair and maintain, and the internal parts may be difficult to disassemble and replace. At present, there is no simple and stable clamp that can better avoid damage to the outer ring of deep groove ball bearings during the clamping and installation process. Summary of the invention

DETAILED DESCRIPTION

[0027] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0028] like Figure 1-Figure 7 A special fixture for clamping and installing the outer ring of a deep groove ball bearing shown in the figure comprises a base plate 1, a fixed seat 2 is fixedly installed in the middle of the upper surface of the base plate 1, the front and rear ends of the base plate 1 are respectively fixedly connected to end plates 7, the front and rear ends of the fixed seat 2 are respectively connected to a movable plate 5 through a telescopic mechanism, the side of the movable plate 5 away from the fixed seat 2 is fixedly connected to two clamping blocks 6, the front and rear ends of the upper surface of the base plate 1 are respectively fixedly connected to soft blocks 8, and the soft block 8 is located between the two clamping blocks 6, the front and rear ends of the two side surfaces of the base plate 1 are respectively inserted with limiting columns 9 through elastic mechanisms, and the end surface of the limiting column 9 away from the base plate 1 is connected to a movable block 19 through a reset mechanism;

[0029] When positioning is completed, the status is as follows Figure 6 , Figure 7 As shown, the upper side of the bearing outer ring 28 is clamped and fixed by the clamping block 6 and the end plate 7 , and the moving block 19 is against the inner wall of the ring track 29 .

[0030] like Figure 1 As shown, the telescopic mechanism includes a telescopic cylinder 3 fixedly embedded on the outer surface of the fixed seat 2, the telescopic end of the telescopic cylinder 3 is fixedly connected to the outer surface of the moving plate 5, and the outer surface of the fixed seat 2 and the two sides close to the telescopic cylinder 3 are respectively slidably inserted with guide rods 4, and one end of the guide rod 4 is fixedly connected to the outer surface of the moving plate 5. By controlling the telescopic cylinder 3 to extend and retract, the moving plate 5 is moved. In this process, the guide rod 4 will slide forward and backward relatively along the fixed seat 2, thereby improving the stability of the moving plate 5 during movement.

[0031] like Figure 4 As shown, the elastic mechanism includes a square hole 10 opened on the inner side of the bottom plate 1, one end of the limit column 9 is inserted into the side of the bottom plate 1 and extends into the square hole 10, and one end of the limit column 9 is fixedly connected to a sliding plate 12, the sliding plate 12 slides into the inner side of the square hole 10, and a compression spring 11 is arranged on the inner side of the square hole 10, and the compression spring 11 is located on the side of the sliding plate 12 away from the limit column 9. When the limit column 9 is pushed, the sliding plate 12 will slide along the inner side of the square hole 10, and when the limit column 9 is no longer pushed, it will be reset 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, and a dial plate 13 is fixedly connected to the lower side of the sliding plate 12, and the dial plate 13 passes through the inner side of the sliding opening 14. By toggling the dial plate 13, the sliding plate 12 can be moved, and two fixed sleeves 15 are fixedly connected to the lower surface of the bottom plate 1, and a pull plate 16 slides through the inner side of each fixed sleeve 15, and the ends of the two pull plates 16 that are close to each other are fixedly connected to a pulling block 18, and the ends of the two pull plates 16 that are far away from each other are fixedly connected to a concave strip 17, and the ends of the concave strip 17 cross the inner side of the sliding opening 14 respectively. After the concave strip 17 moves in the direction away from the sliding opening 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 plates 13 in a limited position. At this time, the limit column 9 will be retracted into the inner side of the bottom plate 1. This state is suitable for clamping a heavier bearing outer ring 28. Due to its heavy weight, it is not easy to shake, and this part of the mechanism does not need to be used for auxiliary stability.

[0033] like Figure 6 , Figure 7 As shown, the reset mechanism includes a convex groove 22 provided on the end surface of the limiting column 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, and two reset springs 24 are sleeved on the outer surface of the fixing rod 23, and the two reset springs 24 are respectively located on the front and rear surfaces of the convex block 21. The two reset springs 24 are used to balance the position of the convex block 21 to ensure 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 end of the moving block 19 close to the bottom plate 1 is provided with a guide surface 20, and the other end of the moving block 19 is provided with a guide edge 25. The guide surface 20 plays an auxiliary role when the limit column 9 is retracted into the inner side of the bottom plate 1, preventing the moving block 19 from hitting the surface of the bottom plate 1 when it is retracted in the unreset 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 fixing seat 2, and a mounting portion 27 is fixedly connected to the upper end of the connecting plate 26. The mounting portion 27 is used to connect with the robot arm to control the movement of the entire clamp.

[0036] The outer rings 28 of the bearings on the front and rear conveyor lines move in the direction close to the base plate 1. After the outer rings 28 of the bearings are sleeved on the outer side of the end of the base plate 1, the base plate 1 is moved upward, and then the telescopic cylinder 3 is controlled to extend so that the movable plate 5 moves, and the clamping block 6 cooperates with the end plate 7 to clamp and fix the upper side of the outer rings 28 of the bearings. Then, as the robot arm drives the connecting plate 26 to move, the outer rings 28 of the bearings are moved, and the clamping process is convenient.

[0037] During the clamping process, the inner wall of the bearing outer ring 28 will contact the soft block 8, thereby preventing the bearing outer ring 28 from being damaged due to bumps and vibrations during the clamping process.

[0038] Before the clamping block 6 is clamped, when the base plate 1 moves up, the moving block 19 will slide to the inner wall of the circle 29. During this process, the convex block 21 slides back and forth along the inner side of the convex groove 22, squeezing the front or rear return spring 24. In addition, under the action of the gravity of the bearing outer ring 28, the moving block 19 and the limit column 9 will be squeezed to move toward one side of the base plate 1, and 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 to quickly stabilize, avoiding the problem of long-term shaking caused by point contact between the inner wall of the bearing outer ring 28 and the surface of the soft block 8.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention.
