A first crank 803 is fixedly mounted on the other end of the stud 802. On the basis of positioning, the stud 802 on the first fixing seat 801 is shaken by the first crank 803, so that the stud 802 is threadedly extended and retracted at the first fixing seat 801. At the same time, one end of the stud 802 rotates to push the clamping block 804 to slide, and the clamping block 804 cooperates with the second fixing block 2 to facilitate the stable clamping and fixing of the bearing seat.

[0026] The positioning mechanism 5 includes a positioning frame 502, which is symmetrically slidably connected to the outside of the mounting frame 1. A through hole 501 is opened on the inside of the mounting frame 1. The inside of the through hole 501 is rotatably connected to the same bidirectional screw 505. The lower end of the positioning frame 502 is fixedly connected to a connecting block 504, which is slidably connected to the inside of the through hole 501. The connecting block 504 is threadedly connected to the outside of the bidirectional screw 505. The inner sides of the opposite surfaces of the positioning frame 502 are rotatably connected to rollers 503. The outside of the bidirectional screw 505 is provided with an operating mechanism 10, which includes a bottom groove 101, a bottom groove 102, and a bottom groove 103. 1 is opened at the lower end of the mounting frame 1, the middle part of the bidirectional screw 505 is rotatably connected to the inner side of the bottom groove 101, and the outer side of the bidirectional screw 505 is fixedly installed with the first bevel gear 102.

The second bevel gear 103 and the first bevel gear 102 are meshed. Before clamping the bearing seat, first press one side of the bearing seat against the second fixed block 2, and then use the second crank 105 to shake The rotating rod 104 causes the second bevel gear 103 connected to the rotating rod 104 to mesh with the first bevel gear 102, and the bidirectional screw 505 connected to the first bevel gear 102 can rotate at the through hole 501. Due to the rotation of the bidirectional screw 505, the two connecting blocks 504 connected by the outer thread slide, and at the same time, the connecting block 504 drives the positioning frame 502 with the roller 503 to slide close to each other on the mounting frame 1. When the positioning frames 502 are close to each other, they can be positioned by contacting the rollers 503 with both ends of the bearing seat, thereby facilitating the positioning and clamping of the bearing seat. The workload of workers in measurement and positioning is greatly reduced, and the drilling processing of the bearing seat is also convenient; under the rotation effect of the roller 503, after positioning, the bearing seat can be directly clamped and fixed in cooperation with the clamping mechanism 8; the two ends of the bidirectional screw 505 are located at the through hole 501 and the corresponding external threads are opposite, and the rotating rod 104 is limited and rotated in the mounting frame 1 and cannot be removed.
