Description

Technical Field

[0001] This utility model relates to metallurgical fixture technology, and more particularly to a bearing assembly fixture. Background Technology

[0002] When installing deep groove ball bearings, a cage needs to be installed. Simultaneously, the distance between the balls in the bearing must be evenly distributed to facilitate cage insertion. Currently, automated equipment can automatically distribute the balls evenly; however, for small businesses, such equipment requires significant space and has a high purchase cost. Manual ball distribution introduces errors, affecting cage installation and reducing efficiency. Therefore, a bearing assembly fixture is needed to improve assembly efficiency. Utility Model Content

[0003] In order to overcome the defects of the existing technology, this utility model proposes a bearing assembly fixture.

[0004] A bearing assembly fixture, comprising:

[0005] Base;

[0006] A first positioning component is provided on the base. The first positioning component has an outer ring and an inner ring. An installation area is formed between the outer ring and the inner ring. Multiple positioning posts are provided in the installation area.

[0007] A second positioning component is provided on the base. The second positioning component has a support surface, and the support surface has a support ring and a positioning ring. The positioning ring is located in the middle of the support ring, and the positioning ring has multiple positioning rods.

[0008] In this bearing assembly fixture of the present invention, a first spring is provided in the mounting area. The first spring is sleeved on the outside of the inner ring and contacts the outer wall of the inner ring.

[0009] In this bearing assembly fixture of the present invention, a second spring is also provided in the mounting area. The second spring contacts the inner wall of the outer ring, and the diameter of the second spring is larger than the diameter of the first spring.

[0010] In this bearing assembly fixture of the present invention, the positioning post is positioned between the first spring and the second spring, and the positioning post is provided with symmetrically arranged guide slopes.

[0011] In this bearing assembly fixture of the present invention, the height of the support ring is higher than the height of the support surface, but lower than the height of the positioning ring.

[0012] The bearing assembly fixture of this utility model has the following advantages: the bearing assembly fixture changes the distance between the balls by using a first positioning element to make the distance between the balls equal, and then transfers them to a second bracket on a second positioning element. The second bracket quickly engages with the balls and prevents the balls from falling off. Finally, the first ball is placed on the second bracket, which can improve assembly accuracy and achieve rapid assembly, thereby further improving assembly efficiency. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figures 1 to 6 As shown, this bearing assembly fixture of the present invention includes a base 1, a first positioning member 2 and a second positioning member 3. The first positioning member 2 and the second positioning member 3 are provided with multiple positioning blocks 4. The first positioning member 2 and the second positioning member 3 are fixed to the base 1 by the cooperation of bolts and positioning blocks 4.

[0021] like Figure 4 and 5 As shown, the bearing 5 includes an inner ring 6, an outer ring 26, balls 7, and a cage 8. The cage 8 is composed of a first support 9 and a second support 10. Both the first support 9 and the second support 10 are composed of connecting sections 11 and arc-shaped sections 12, which are connected end-to-end. The first support 9 and the second support 10 are formed by multiple connecting sections 11 and arc-shaped sections 12. Figure 6As shown, the arc segment 12 on the first bracket 9 has a minor arc angle, while the arc segment 12 on the second bracket 10 has a major arc angle. This ensures that the connecting segment 11 on the second bracket 10 is positioned above the center of the ball 7, and that the center of the ball 7 is not on the same horizontal plane as the connecting segment 11 on the first and second brackets 9 and 10. In other words, the arc angle of the arc segment 12 on the second bracket 10 is greater than 180°, providing sufficient clamping force to prevent the ball 7 from shifting position. Furthermore, after the first bracket 9 and ball 7 are properly installed, flipping the bearing 5 ensures that the second bracket 10 and ball 7 do not detach. This facilitates the installation of the first bracket 9 and second bracket 10 after flipping the bearing 5, thus confining the ball 7 to its position between the first and second brackets 9 and 10. Finally, the first bracket 9 and second bracket 10 are fixed together using rivets 13.

[0022] The first positioning element 2 is set on the base 1. The first positioning element 2 is provided with an outer ring 14 and an inner ring 15. An installation area 16 is formed between the outer ring 14 and the inner ring 15. Multiple positioning posts 17 are provided in the installation area 16.

[0023] A first spring 18 is provided within the mounting area 16. The first spring 18 is sleeved on the outside of the inner ring 15 and contacts the outer wall of the inner ring 15. A second spring 19 is also provided within the mounting area 16. The second spring 19 contacts the inner wall of the outer ring 14, and the diameter of the second spring 19 is larger than the diameter of the first spring 18.

[0024] The first spring 18 is used to support the inner ring 6, while the second spring 19 is used to support the outer ring 26.

[0025] The positioning post 17 is positioned between the first spring 18 and the second spring 19, and the positioning post 17 is provided with symmetrically arranged guide slopes 20.

[0026] After the balls 7 are placed in the inner ring 6 and the outer ring 26, the distance between the balls 7 will change, requiring a retainer 8 to limit the position of the balls 7. Before installing the retainer 8, the balls 7 need to be evenly arranged. Therefore, after the balls 7 are placed in the inner ring 6 and the outer ring 26, they only need to be slightly moved to separate them, and then placed in the mounting area 16. The inner ring 6 compresses the first spring 18, and the outer ring 26 compresses the second spring 19, keeping the positioning pin 17 in position with the balls 7. This allows the guide ramp 20 to push the balls 7. When the contact surface of the positioning pin 17 contacts the balls 7, the position of the balls 7 is kept equal. Then the bearing 5 can be removed.

[0027] The second positioning component 3 is mounted on the base 1. The second positioning component 3 has a support surface 21, and the support surface 21 has a support ring 22 and a positioning ring 23. The positioning ring 23 is located in the middle of the support ring 22, and the positioning ring 23 has multiple positioning rods 24. The height of the support ring 22 is higher than the height of the support surface 21, but lower than the height of the positioning ring 23.

[0028] When the distance between the balls 7 is equal, the bearing 5 can be removed. Before placing it on the second positioning member 3, the second bracket 10 is placed on the positioning rod 24, keeping the positioning rod 24 in the fixing hole 25 of the rivet 13. Then, the bearing 5 removed from the first positioning member 2 is placed on the second positioning member 3, keeping the balls 7 in the middle of the arc segment 12 of the second bracket 10, restricting the position of the balls 7, and also preventing the second bracket 10 from falling off the balls 7. Then, the bearing 5 is removed, and the first bracket 9 is fitted with the second bracket 10. Finally, the rivet 13 is placed in the fixing hole 25, and it is transferred to the equipment to apply pressure to the rivet 13, so that its deformation restricts the position of the first bracket 9 and the second bracket 10.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
