The clamping ring is usually clamped on the outer wall of the bearing and can be adjusted according to the size of the bearing. It is suitable for bearings of different models, but it is generally necessary to continuously apply force away from the bearing, which is more laborious when clamping and the clamping stability is not high. The mounting plate is usually fixed on the inside of the bearing, but its size is not adjustable. Different models of mounting plates need to be made according to the size of the bearing, which has great limitations in use. In addition, the existing bearing assembly fixture does not have a positioning function and cannot guarantee good assembly accuracy. Utility Model Content

The push rods 2 are evenly arranged to provide uniform supporting force for the bearing, thereby ensuring stable clamping. The push rods 2 are slidably connected to the side wall of the support body 1. One end of the push rod 2 extends out of the support body 1 and is connected to a push block 3. The side of the push block 3 away from the push rod 2 is connected to a rubber pad 13. The rubber pad 13 can prevent the push block 3 from damaging the bearing, and increase the friction between the push block 3 and the bearing, thereby improving the clamping stability of the fixture.

The screw rod 4 is threadedly connected to the upper wall of the support body 1. The upper end of the screw rod 4 extends out of the support body 1 and is connected to a knob 8. The lower end of the screw rod 4 is arranged in the support body 1 and is rotatably connected to the movable plate 5. The upper part of the movable plate 5 is connected to the upper wall of the support body 1 through a symmetrically arranged multi-stage telescopic rod 14. The multi-stage telescopic rod 14 can prevent the movable plate 5 from rotating with the screw rod and can also make it rise and fall stably.
[0021] Combined with Figure 1 , multiple transmission rods 6 are rotatably connected and arranged below the movable plate 5, the transmission rods 6 correspond to the top rods 2 one by one, the lower end of the transmission rod 6 is rotatably connected to the end of the top rod 2 away from the top block 3, the upper and lower ends of the spring 7 are respectively connected to the movable plate 5 and the lower wall of the support body 1, the spring 7 is arranged at the center below the movable plate 5 and is always in an extended state, the spring 7 can always provide a downward pulling force to the movable plate 5, to prevent the movable plate 5 from moving upward during the bearing assembly process and causing the top block 3 to detach from the bearing, thereby ensuring the stable clamping of the fixture.
[0022] Combined with Figure 1 , Attachment Figure 2 The positioning structure is connected and arranged below the support body 1. There are two positioning structures and they are arranged on the same diameter of the lower wall of the support body 1, which is convenient for positioning the bearing assembly position in different directions at the same time, and the positioning accuracy is high.
[0023] Combined with Figure 1 The positioning structure includes a fixed tube 9 rotatably connected to the lower wall of the support body 1, an L-shaped frame 10 is slidably connected inside the fixed tube 9, and the positioning rod 12 is symmetrically connected to a slide bar at one end inside the L-shaped frame 10. A slide groove matching the slide bar is provided in the L-shaped frame 10. The slide bar cooperates with the slide groove to ensure the stable movement of the positioning rod 12 and prevent it from detaching from the L-shaped frame 10, which is stable and reliable.
[0024] Combined with Figure 1 , Attachment Figure 2One end of the L-shaped frame 10 is connected to the inner wall of the fixed tube 9 through a spring 11, and a positioning rod 12 is slidably connected in the extended end of the L-shaped frame 10. The side wall of the extended end of the positioning rod 12 is flush with the side wall of the L-shaped frame 10, and the extended end of the positioning rod 12 is an inclined surface, which is convenient for accurately judging whether the L-shaped frame 10 is in contact with the assembly object, thereby achieving precise positioning and improving assembly accuracy.
[0025] Specific implementation of the utility model: Turn the knob 8 to make the screw rod 4 drive the movable plate 5 to move up, and at the same time the multi-stage telescopic rod 14 contracts, the movable plate 5 drives the end of the transmission rod 6 to move up, and the transmission rod 6 drives the push rod 2 to move into the support body 1, and the support body 1 is placed on the inner side of the bearing, and the knob 8 is turned in the opposite direction to move the push block 3 away from the support body 1 until the push block 3 contacts the inner wall of the bearing and tightens it, so that the clamp can be fixed on the inner side of the bearing. At this time, the spring 7 is still in an extended state to prevent the screw rod 4 from moving up, and the support body 1 is held by hand to assemble the bearing, and the L-shaped 1 and rotate the fixing tube 9 to move the end of the positioning rod 12 away from the center of the support body 1 until the L-shaped frame 10 is located below the bearing and the assembly object. Pull the positioning rod 12 outward to release the L-shaped frame 10. The spring 11 drives the L-shaped frame 10 to move so that the L-shaped frame 10 contacts the lower wall of the assembly object. Observe whether the positioning rod 12 contacts the assembly object. If so, it indicates that the assembly is successful. If not, continue to adjust the relative angle between the bearing and the assembly object until they contact. Then rotate the knob 8 to move the top block 3 away from the inner wall of the bearing and take out the support body 1.
