[0046] A matching sleeve 9, the matching sleeve 9 is fixedly connected to the lower end of the base 8;

[0047] A bearing 15 connected to the matching sleeve 9; and

[0048] The clamping mechanism is arranged on the matching sleeve 9 to fix the bearing 15 .

[0049] In a specific embodiment of the present invention, the housing 1 is the main body of the entire tooling, and is usually made of a solid metal material, such as steel or aluminum alloy, to ensure that it has sufficient strength and durability. A U-shaped opening 2 is provided on the circumferential surface of the housing 1 to accommodate the threaded rod 5 and other related components. The design of the U-shaped opening 2 should ensure that the threaded rod 5 can move up and down smoothly. The threaded rod 5 is connected to the housing 1 by threads and can move up and down in the housing 1. This design allows the user to adjust its position by rotating the threaded rod 5, thereby applying pressure to perform a ball pressing operation. The upper end of the threaded rod 5 is fixedly connected to a top seat 6, and the circumferential surface of the top seat 6 is fixedly connected to a handle 7. The design of the top seat 6 and the handle 7 facilitates the user to manually rotate the threaded rod 5. The sleeve block 3 is connected to the upper end of the housing 1 and is threadedly connected to the housing 1 by a bolt 4. The function of the sleeve block 3 is to provide a stable support point, and its position can be adjusted by adjusting the bolt 4 to adapt to bearings 15 of different sizes. The base 8 is fixedly connected to the lower end of the threaded rod 5 as a support base for the threaded rod 5. The design of the base 8 should ensure that it can withstand the pressure from the threaded rod 5 and remain stable. The matching sleeve 9 is fixedly connected to the lower end of the base 8 for mounting and fixing the bearing 15. The design of the matching sleeve 9 should match the outer diameter of the bearing 15 to ensure that the bearing 15 can be firmly mounted thereon. The bearing 15 is connected to the matching sleeve 9. The bearing 15 is usually a deep groove ball bearing to be processed, and the ball pressing operation needs to be performed through the tooling. The clamping mechanism is arranged on the matching sleeve 9, including an opening 17, a sleeve 10, a circular groove 11 and a clamping assembly. The opening 17 is opened on the matching sleeve 9, the sleeve 10 is sleeved and connected in the opening 17, and the circular groove 11 is opened at the side end of the sleeve 10. The clamping assembly includes a first spring 12, a ball 13 and a nut 14. The first spring 12 is fixedly connected in the circular groove 11, the ball 13 is fixedly connected to the side end of the first spring 12, and the circular groove 11 and the ball 13 match. The nut 14 is threadedly connected to the circumferential surface of the circular groove 11, and the other side end of the nut 14 is connected to the matching sleeve 9. The main function of the clamping mechanism is to fix the bearing 15 to prevent it from moving during the ball pressing process. The bearing 15 can be tightened or loosened by adjusting the nut 14.

[0050] For details, please refer to Figure 1-6 The opening 17 is opened on the matching sleeve 9 , the sleeve 10 is sleeved and connected in the opening 17 , the circular groove 11 is opened at the side end of the sleeve 10 , and the clamping assembly is arranged in the circular groove 11 to limit the bearing 15 .

[0051] In this embodiment: the opening 17 is opened on the side of the matching sleeve 9, and its shape and size should match the sleeve 10 to ensure that the sleeve 10 can be smoothly inserted and fixed. The opening 17 provides a mounting position for the sleeve 10, and the insertion of the sleeve 10 can achieve the limit of the bearing 15. The sleeve 10 is a cylindrical component, and its outer diameter matches the inner diameter of the opening 17 so that the sleeve 10 can be tightly inserted into the opening 17. The sleeve 10 is usually made of a strong metal material, such as steel or aluminum alloy, to ensure that it has sufficient strength and durability. The sleeve 10 is sleeved and connected in the opening 17, and can be secured by threaded connection, pressing or other fixing methods. The circular groove 11 is opened at the side end of the sleeve 10, and its shape and size should match the ball 13 in the clamping assembly to ensure that the ball 13 can move freely in the circular groove 11 but will not fall out. The circular groove 11 provides a mounting position for the clamping assembly, and the limit of the bearing 15 is achieved through the action of the clamping assembly.

[0052] For details, please refer to Figure 1-6 The clamping assembly includes a first spring 12, a ball 13 and a nut 1-4. The first spring 12 is fixedly connected in the circular groove 11. The ball 13 is fixedly connected to the side end of the first spring 12. The circular groove 11 and the ball 13 match. The nut 1-4 is threadedly connected to the circumferential surface of the circular groove 11. The other side end of the nut 1-4 is connected to the matching sleeve 9.

[0053] In this embodiment: the first spring 12 is fixedly connected in the circular groove 11. Usually, one end of the first spring 12 is fixed on the bottom or side wall of the circular groove 11, and the other end is connected to the ball 13. The first spring 12 provides elastic force, so that the ball 13 can be pressed into the circular groove 11 under the action of external force, and automatically pops out after the external force is removed, thereby limiting the bearing 15. The ball 13 is fixedly connected to the side end of the first spring 12. The diameter of the ball 13 should be slightly smaller than the diameter of the circular groove 11 to ensure that it can move freely in the circular groove 11 but will not fall out. The ball 13 is usually made of hard metal material, such as steel balls, to ensure that it has sufficient hardness and wear resistance. Under the action of the first spring 12, the ball 13 can respond to the pressure applied from the outside, thereby limiting the bearing 15. When the bearing 15 is installed in place, the ball 13 will be pressed into the circular groove 11; when the bearing 15 needs to be removed, the ball 13 will pop out under the action of the first spring 12, loosening the limit of the bearing 15. The nut 14 is threadedly connected to the circumferential surface of the circular groove 11. The other side end of the nut 14 is connected to the matching sleeve 9, and its position in the circular groove 11 can be adjusted by rotating the nut 14. The main function of the nut 14 is to adjust and fix the position of the ball 13. By tightening or loosening the nut 14, the range of movement of the ball 13 in the circular groove 11 can be controlled, thereby achieving the tightening or loosening of the bearing 15.

[0054] For details, please refer to Figure 1-6 A second spring 16 is sleeved and connected inside the U-shaped opening 2 , and the second spring 16 matches the threaded rod 5 .

[0055] In this embodiment: the U-shaped opening 2 is opened on the circumferential surface of the housing 1, and its shape is U-shaped, which is used to accommodate the threaded rod 5 and other related parts. The U-shaped opening 2 provides a channel so that the threaded rod 5 can move up and down therein, and through the design of the U-shaped opening 2, the threaded rod 5 can be easily installed and removed. The second spring 16 is sleeved and connected in the U-shaped opening 2. Specifically, one end of the second spring 16 is fixed on the bottom or side wall of the U-shaped opening 2, and the other end is connected to the threaded rod 5. The second spring 16 is usually made of high-strength spring steel to ensure that it has sufficient elasticity and durability. The outer diameter of the second spring 16 should be slightly smaller than the inner diameter of the U-shaped opening 2 to ensure that it can move smoothly in the U-shaped opening 2. At the same time, the length and elastic coefficient of the second spring 16 should be selected according to actual needs to ensure that it can provide appropriate buffering and reset force. The threaded rod 5 is connected to the housing 1 by threads and moves up and down in the U-shaped opening 2. The lower end of the threaded rod 5 is fixedly connected to the base 8. The threaded rod 5 adjusts its position in the housing 1 by rotating, thereby applying pressure to perform the ball pressing operation. The second spring 16 provides a certain buffer and reset force to ensure that the threaded rod 5 moves smoothly during the operation and automatically resets after the operation is completed.

[0056] For details, please refer to Figure 1-6 The upper end of the threaded rod 5 is fixedly connected to a top seat 6, and the circumferential surface of the top seat 6 is fixedly connected to a handle 7.

[0057] In this embodiment: the threaded rod 5 is connected to the housing 1 by threads and can move up and down in the U-shaped opening 2. The lower end of the threaded rod 5 is fixedly connected to the base 8. The threaded rod 5 is usually made of high-strength metal materials, such as steel or stainless steel, to ensure that it has sufficient strength and durability. By rotating the threaded rod 5, its position in the housing 1 can be adjusted, so that pressure is applied to perform the ball pressing operation. The top seat 6 is fixedly connected to the upper end of the threaded rod 5. The top seat 6 is usually fixed to the threaded rod 5 by welding, bolting or other fastening methods. The top seat 6 is usually made of a strong metal material, such as steel or aluminum alloy, to ensure that it can withstand the pressure from the threaded rod 5 and remain stable. The design of the top seat 6 should ensure that it can provide a stable platform for installing the handle 7 and other components that may be required. The handle 7 is fixedly connected to the circumferential surface of the top seat 6. The handle 7 is usually fixed to the top seat 6 by welding, bolting or other fastening methods. The handle 7 is usually made of a strong metal material, such as steel or aluminum alloy, or a treated plastic material to ensure that it has sufficient strength and a comfortable feel. The design of the handle 7 should conform to the principle of ergonomics to ensure that the user can conveniently hold and apply force during operation. The shape and size of the handle 7 should be convenient for the user to manually rotate the threaded rod 5.

[0058] For details, please refer to Figure 1-6 The circumferential surface of the housing 1 is provided with an anti-slip groove 18 .

[0059] In this embodiment: the anti-skid groove 18 increases the friction coefficient of the surface of the housing 1, making it more stable and less likely to slip when the user holds and operates. This is especially important for operations that require greater pressure. The design of the anti-skid groove 18 takes into account ergonomic principles, which can reduce the pressure on the hand to a certain extent and improve the user's comfort. During operation, especially when the tooling needs to be rotated or moved, the anti-skid groove 18 can prevent accidents caused by hand slippage, thereby improving the safety of operation.

[0060] For details, please refer to Figure 1-6 A rectangular seat 301 is fixedly connected to the side end of the sleeve block 3, a reinforcing rib 302 is fixedly connected between the rectangular seat 301 and the sleeve block 3, and a groove 19 is opened on the threaded rod 5.

[0061] In this embodiment: the rectangular seat 301 is to provide an additional mounting point or support point, which may be used to assist in fixing or connecting other tools to increase the operational stability of the entire device. The reinforcing rib 302 is used to enhance the connection strength between the two to prevent deformation or breakage when pressure is applied. This helps to ensure that the sleeve block 3 and its additional components can still maintain structural integrity and stability when subjected to large external forces. The presence of the groove 19 can be used as a positioning mark to help the operator control the position of the threaded rod.

[0062] For details, please refer to Figure 1-6 A mounting groove 303 is provided at the side end of the rectangular seat 301 , a threaded opening 304 is provided at the side end of the mounting groove 303 , a convex block 305 is slidably connected in the mounting groove 303 , and the convex block 305 matches the groove 19 .

[0063] In this embodiment: the mounting groove 303 provides a sliding space for the protrusion 305. It allows the protrusion 305 to move within a certain range so as to align with the grooves 19 at different positions on the threaded rod 5. The threaded opening 304 is to accommodate a screw or bolt, which is rotated to push or lock the protrusion 305. When the position of the protrusion needs to be adjusted, the screw or bolt in the threaded opening can be loosened, and then tightened again to fix the position of the protrusion after the adjustment. The protrusion 305 is a component that can slide along the mounting groove 303, and its shape and size are designed to match the groove 19 on the threaded rod 5. The main function of the protrusion is to cooperate with the groove to locate or lock the position of the threaded rod 5, ensuring that the threaded rod does not undergo unnecessary displacement during the ball pressing process. The groove 19 provides a corresponding embedding point for the protrusion 305.

[0064] For details, please refer to Figure 1-6 The side end of the protrusion 305 is fixedly connected with a telescopic rod 306 , and the circumferential surface of the telescopic rod 306 is sleeved with a third spring 307 .

[0065] In this embodiment: the presence of the telescopic rod 306 allows the protrusion 305 to not only slide in the mounting groove 303, but also to perform a certain degree of telescopic movement along the direction of the telescopic rod. This provides additional flexibility, allowing the protrusion to better adapt to the grooves 19 at different positions on the threaded rod 5, and can be smoothly embedded even if these grooves are not completely aligned. The third spring 307 is a third spring sleeved on the telescopic rod 306 to provide elastic support for the protrusion 305. When the protrusion is pressed into the mounting groove 303, the third spring will be compressed; once the external force is removed, the spring will push the protrusion back to its original position, thereby automatically embedding into the groove 19 on the threaded rod.

[0066] For details, please refer to Figure 1-6 The side end of the telescopic rod 306 is fixedly connected with a threaded block 308 , and the threaded block 308 is engaged with the threaded opening 304 .

[0067] In this embodiment: the outer surface of the threaded block 308 has a threaded structure that can engage with the internal thread in the threaded opening 304. By rotating the threaded block 308, fine adjustment of the position of the protrusion 305 can be achieved. The inside of the threaded opening 304 is designed with an internal thread that matches the threaded block 308. The threaded opening not only provides a guide for the threaded block, but also allows the position of the protrusion to be adjusted by rotation. When it is necessary to adjust or lock the position of the threaded rod 5, the user first loosens the threaded block 308 at the threaded opening 304 so that the protrusion 305 can be disengaged from the groove 19. Moving the threaded rod Then, the user can freely rotate or move the threaded rod 5 up and down until it reaches the desired working position. When the threaded rod reaches the correct position, the user can rotate the threaded block 308 to make it move along the threaded opening 304, pushing the protrusion 305 into the corresponding groove 19

[0068] The working principle and use process of the present invention are as follows: first, the deep groove ball bearing 15 to be pressed is placed on the matching sleeve 9, and the clamping mechanism on the matching sleeve including the opening 17, the sleeve 10, the circular groove 11 and the clamping assembly are used to fix the bearing to prevent it from moving during operation, and the threaded block 308 at the threaded opening 304 is loosened to allow the protrusion 305 to be disengaged from the groove 19 on the threaded rod 5, and the handle 7 is manually rotated to adjust the position of the threaded rod 5 until the top seat 6 is close to but not in contact with the position where the ball is to be pressed, and the handle 7 is slowly rotated while observing the distance between the top seat 6 and the ball to ensure accurate alignment, and once the desired height is reached, the threaded block 308 is rotated. , so that it moves along the threaded opening 304, pushing the protrusion 305 into the corresponding groove 19, thereby locking the position of the threaded rod 5, and continuing to slowly rotate the handle 7 to apply pressure to press the ball into the bearing 15. During the entire ball pressing process, maintain a stable speed and force to avoid sudden movements or excessive force to prevent damage to the bearing or other components. When the ball is completely pressed in, stop rotating the handle 7, loosen the threaded block 308, and allow the protrusion 305 to escape from the groove 19 so that the position of the threaded rod 5 can be freely adjusted. If it is necessary to continue processing other balls or bearings, repeat the above steps; otherwise, loosen the clamping mechanism and take out the processed bearing.

[0069] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
