A bearing, a through groove matched with the size of the clamping plate 10 is opened inside the movable block 6, one end of the clamping plate 10 passes through the through groove and extends to the inside of the limiting groove 7, the clamping plate 10 is slidably connected with the movable block 6 through the through groove, when the clamping motor 8 is started, the first threaded rod 9 rotates and can drive the clamping plate 10 to slide along the through groove, so that the clamping plate 10 can clamp the bearing seat 4 conveniently and improve the stability of the bearing seat 4 when moving. One end of the roller 12 passes through and extends to the inside of the slide groove 11, and the roller 12 is rollingly connected to the bottom of the slide groove 11, so that when the movable block 6 is moved, the movable block 6 moves more stably and smoothly.

[0023] It should be noted that, by setting up a moving mechanism, when the bearing seat 4 is in the limiting groove 7, the cylinder 5 moves the movable block 6 to conveniently and quickly remove the bearing seat 4. At the same time, the clamping plate 10 clamps the bearing seat 4 to prevent the bearing seat 4 from shaking during movement.

[0024] The adjusting assembly includes a dual-axis motor 13 fixedly mounted inside the base 1, a worm 14 fixedly mounted on the output shaft of the dual-axis motor 13, a fixing plate 15 fixedly mounted on the front and back sides of the placement frame 2, a second threaded rod 16 provided on the front and back sides of the top of the base 1, a worm wheel 17 meshing with the worm 14 fixedly mounted on the outer side of the second threaded rod 16, the movable block 6 is located at the bottom of the bearing seat 4, one end of the second threaded rod 16 penetrates and extends to the top of the fixing plate 15, the second threaded rod 16 is connected to the internal thread of the fixing plate 15, a fixing frame 18 having one end penetrating and extending to the top of the fixing plate 15 is fixedly mounted on the front and back sides of the top of the base 1, the inner wall of the fixing plate 15 is slidably connected to the fixing frame 18, a second bearing movably connected to the second threaded rod 16 is fixedly mounted inside the fixing frame 18 and inside the base 1, the fixing frame 18 makes the rotation of the second threaded rod 16 more stable, while making the movement of the fixing plate 15 more stable.

[0025] It should be noted that, by setting an adjustment component, it is convenient to move bearing seats 4 of different models into the limiting groove 7, and it is convenient to disassemble and assemble bearing seats 4 of different models and sizes, thereby improving the practicality during use.

[0026] The working principle of the above embodiment is as follows: when the bearing seat 4 needs to be disassembled, the cylinder 5 is started to drive the movable block 6 to move to the bottom of the bearing seat 4, and then the double-axis motor 13 is started to drive the worm 14 to rotate. The rotation of the worm 14 drives the worm wheel 17 and the second threaded rod 16 to rotate, and then drives the placement frame 2 to move downward, and at the same time, the roller body 3 and the bearing seat 4 move downward. When one side of the bearing seat 4 moves to the inside of the limit groove 7, the double-axis motor 13 is turned off, and the clamping motor 8 is started again to drive the first threaded rod 9 to rotate. The rotation of the first threaded rod 9 drives the clamping plate 10 to move toward the bearing seat 4. When the clamping plate 10 moves and clamps the bearing seat 4, the cylinder 5 is started again to drive the movable block 6 to move to the side close to the cylinder 5, and drive the bearing seat 4 to move, so that the disassembly of the bearing seat 4 can be completed, and vice versa, the installation of the bearing seat 4 can be completed.
