The limiting mechanism is arranged above the placement tray 2;

[0024] The positioning mechanism includes a mounting frame 6, a first screw 7, a flange 8, a second screw 9 and a moving frame 10. An installation groove 3 is formed on the surface of the workbench 1. The mounting frame 6 is installed inside the installation groove 3. A through groove is formed on the surface of the mounting frame 6. One inner wall of the through groove is fixedly installed with the end of the second screw 9 through a bearing seat. The other end of the second screw 9 and one end of the first screw 7 are respectively fixedly installed on the inner wall of the flange 8.

Moving frames 10 are respectively threadedly connected to the surfaces of the first screw 7 and the second screw 9.

[0025] By respectively arranging movable frames 10 on the side walls of the first screw rod 7 and the second screw rod 9, and the two groups of movable frames 10 are respectively threadedly connected to the side walls of the first screw rod 7 and the second screw rod 9. The opposite ends of the two groups of first screw rods 7 and second screw rods 9 are fixedly installed through a flange 8, so as to drive the first screw rod 7 and the second screw rod 9 to rotate by starting the motor 4, and then make the two groups of movable frames 10 move relatively or away from each other, and the side wall of the movable frame 10 is slidably connected to the inner wall of the placement plate 2. The opposite side walls of the two groups of movable frames 10 respectively abut against the inner wall of the bearing body 19 to fix the bearing body 19, increasing the position of the bearing body 19 placed on the surface of the placement plate 2, and avoiding the offset of the bearing body 19 during assembly, which affects the assembly efficiency of the bearing body 19.

[0026] The thread directions on the surfaces of the first screw rod 7 and the second screw rod 9 are opposite, and the two groups of movable frames 10 move away from or towards each other on the surfaces of the first screw rod 7 and the second screw rod 9.

[0027] By setting the thread directions on the surfaces of the first screw rod 7 and the second screw rod 9 to be opposite, and the movable frames 10 are respectively threadedly connected to the first screw rod 7 and the second screw rod 9, the movable frames 10 move relatively and away from each other on the surfaces of the first screw rod 7 and the second screw rod 9, so as to further support the inner wall of the bearing body 19 by the movable frames 10 and fix and position the bearing body 19.

[0028] Above the opposite side walls of the two groups of movable frames 10, a number of anti-slip pads 11 are respectively arranged, and the number of anti-slip pads 11 respectively abut against the inner wall of the bearing body 19.

[0034] Several groups of rubber pads 17 are respectively arranged on the opposite side walls of the two sets of clamping blocks 15, and the opposite side walls of the two groups of rubber pads 17 are respectively in contact with the side wall of the bearing body 19.

[0035] By setting rubber pads 17 on the opposite side walls of the two sets of clamping blocks 15 respectively, the friction between the clamping blocks 15 and the outer wall of the bearing body 19 is increased to enhance the stability of clamping the bearing body 19.

[0036] Pad blocks 18 are respectively arranged on the surface of the placing plate 2 between the groove 13 and the square groove 12. The bearing body 19 is placed above the pad blocks 18. By arranging pad blocks 18 on the surface of the placing plate 2 between the groove 13 and the square groove 12 respectively, and the bearing body 19 is arranged on the surface of the pad blocks 18, the bearing body 19 is supported by the pad blocks 18.
