[0027] The outer surface of the limiting toothed disc 13 is processed with tooth blocks, and the limiting clamping block 20 is embedded between the tooth blocks;

[0028] Specifically, Figure 1 and Figure 2 As shown, when it is necessary to flip the bearing seat between the fixed plates 10, the drive motor 7 is started, and the drive motor 7 drives the fixed plate 10 and the bearing seat between the fixed plates 10 to rotate through the connecting shaft 12, so as to facilitate the processing of different surfaces of the bearing seat. When the fixed plate 10 is rotated to a suitable position, the hydraulic cylinder 15 is started, and the hydraulic cylinder 15 drives the limit block 20 to move through the connecting block 14, so that the limit block 20 can be embedded between the tooth blocks outside the limit toothed disc 13, and the limit toothed disc 13 is limited to prevent the connecting shaft 12 from accidentally driving the bearing seat between the fixed plates 10 to rotate accidentally.

[0029] Embodiment 2: An electric push rod 19 is installed at the bottom end of the workbench 2, and a mounting plate 21 is installed at the top of the electric push rod 19. Both sides of the workbench 2 are fixedly connected with hinge shafts 18, and the outer side of the hinge shaft 18 is movably hinged with a half-page gear 17. Second hinge rods 23 are movably hinged on both sides of the mounting plate 21, and a first hinge rod 22 is movably hinged between the second hinge rod 23 and the half-page gear 17. Tooth plates 6 are movably connected on both sides of the top of the workbench 2, and both ends of the tooth plate 6 are fixedly connected with limiting blocks 16. Limiting grooves 5 are provided at the tops of both ends of the workbench 2. The limiting blocks 16 are arranged inside the limiting grooves 5.

[0030] Specifically, Figure 1 and Figure 2As shown, put the bearing seat between the fixed plates 10, and then start the electric push rod 19. The electric push rod 19 drives the mounting plate 21 to descend, so that the second hinge rod 23 and the first hinge rod 22 can rotate the half-page gear 17. The rotation of the half-page gear 17 can drive the tooth plate 6 to move left and right, so that the fixed plate 10 at the top of the tooth plate 6 can clamp and limit the bearing seat. Limiting and fixing the bearing seat can prevent the bearing seat from accidentally shifting and affecting the processing.

[0032] Specifically, Figure 1 and Figure 4 As shown, when the bearing seat accidentally falls from between the fixing plates 10, the sponge 11 and the spring 25 will cushion the bearing seat, thereby reducing the impact force of the bearing seat and protecting the bearing seat and the buffer plate 24. The buffer rod 27 can support and limit the buffer plate 24 to prevent the spring 25 from driving the buffer plate 24 to shake left and right.

[0033] Working principle: When the utility model is in use, the bearing seat is placed between the fixed plates 10, and the electric push rod 19 is started after it is placed. The electric push rod 19 drives the mounting plate 21 to descend, so that the second hinge rod 23 and the first hinge rod 22 can make the half-page gear 17 rotate. The rotation of the half-page gear 17 can drive the tooth plate 6 to move left and right, so that the fixed plate 10 at the top of the tooth plate 6 can clamp and limit the bearing seat, and then the bearing seat is processed. When the tooth plate 6 moves, the limit groove 5 will limit the tooth plate 6 through the limit block 16. When it is necessary to flip the bearing seat between the fixed plates 10, the drive motor 7 is started, and the drive motor 7 drives the fixed plate 10 through the connecting shaft 12. The bearing seat between the plate 10 and the fixed plate 10 rotates, so as to facilitate the processing of different surfaces of the bearing seat. When the fixed plate 10 rotates to a suitable position, the hydraulic cylinder 15 is started. The hydraulic cylinder 15 drives the limit block 20 to move through the connecting block 14, so that the limit block 20 can be embedded between the tooth blocks outside the limit toothed disk 13, and the limit toothed disk 13 is limited to prevent the connecting shaft 12 from accidentally driving the bearing seat between the fixed plates 10 to rotate accidentally. When the bearing seat accidentally falls from between the fixed plates 10, the sponge 11 and the spring 25 will buffer the bearing seat, thereby reducing the impact force of the bearing seat and protecting the bearing seat and the buffer plate 24.
