In this embodiment, the control switch is a pneumatic switch.

[0038] A workbench fixing plate 11 is provided on the workbench 10. In this embodiment, there are two workbench fixing plates 11. One side of each workbench fixing plate 11 is provided with a fixing plate U-shaped hole groove 11a that cooperates with the connecting component 50, and the other side of one of the workbench fixing plates 11 is provided with a first curved surface 11b for guiding the sleeve 1.

[0039] The first cylinder assembly 20 is movably mounted on the workbench 10 and engages with the workbench fixed plate 11. In this embodiment, the first cylinder assembly 20 comprises a first cylinder 21, mounted on one side of the workbench 10 and connected to the control switch, a first cylinder movable plate 22 connected to the first cylinder 21, and a second cylinder movable plate 23 connected to the first cylinder movable plate 22. To ensure securement of the connecting assembly, a first slot 22a and a second slot 23a are provided on one side of the first and second cylinder movable plates 22 and 23. These slots, when combined with the U-shaped slots 11a of the two workbench fixed plates 11, form a circular slot. Furthermore, to provide guidance for the sleeve, a second curved surface 23b is provided on the other side of the second cylinder movable plate 23 to guide the sleeve 1. The first curved surface 11b and the second curved surface 23b combine to form a circular surface.

[0040] The second cylinder device 30 is movably disposed at the bottom of the workbench 10 and is provided for mounting the shaft sleeve 1. In this embodiment, the second cylinder device 30 includes a second cylinder 31 disposed at the bottom of the workbench 10 and connected to a control switch, and a circular shaft 32 connected to the second cylinder 31. When in use, the second cylinder 31 can drive the circular shaft 32 to move up and down.

[0041] A third cylinder assembly 40 is movably mounted on the side of the workbench 10 and is used to secure the shaft sleeve 1. In this embodiment, the third cylinder assembly 40 comprises a third cylinder 41, mounted on the other side of the workbench 10 and connected to a control switch, and a quick-clamp arm 42 movably connected to the third cylinder 41. During operation, the third cylinder 41, under control of the control switch, moves the quick-clamp arm 42.

[0042] The connecting assembly 50 is disposed on the workbench 10 and cooperates with the first cylinder device 20, the workbench fixing plate 11, and the bearing 1. In this embodiment, the connecting assembly 50 includes a cylindrical pin 51 that is sequentially inserted into the first hole slot 22a, the second hole slot 23a, and the U-shaped hole slot 11a of the fixing plate, and a top plate 52 that is sleeved on the cylindrical pin 51 and welded to the shaft sleeve 1 and the cylindrical pin 51. Specifically, there are four cylindrical pins 51.

[0043] The working principle of this utility model is as follows:

[0044] First, clean the workbench 10 and the workpiece surface, remove the scrap iron, dirt and dust on the platform surface, and ensure that there is no foreign matter between the platform and the workpiece. Then adjust the workbench 10 to the exhaust and pressure relief state through the air pressure switch. The first cylinder 21 is in an inward contraction, and the first cylinder movable plate 22 and the second cylinder movable plate 23 on the first cylinder 21 are pulled apart from the workbench fixed plate 11. The second cylinder 31 is in a downward contraction state, and the third cylinder 41 is in a downward contraction state, pulling the quick clamping arm 42 upward to open. Then, put the four cylindrical pins 51 into the first cylinder 21 in sequence. The bottoms of the four cylindrical pins 51 are flush with the plane of the workbench 10 in the hole grooves 22a, 23a, and 11a of the first cylinder movable plate 22 and the second cylinder movable plate 23 and the workbench fixed plate 11. The sleeve 1 is placed on the round shaft 32 of the second cylinder 31, and the air pressure switch is turned on (the air pressure switch controls the movement of the first cylinder 21 and the second cylinder 31 at the same time). The workbench 10 is adjusted to the air intake and pressurized state, and the first cylinder 21 is stretched outward, pushing the first cylinder movable plate 22 and the second cylinder movable plate 23 connected to the first cylinder 21 outward. During the movement, the first cylinder movable plate 22 and the second cylinder movable plate 23 are used to push the first cylinder 21 outward. The plate 22 and the second cylinder movable plate 23 and the first curved surface 11b and the second curved surface 23b of the workbench fixed plate 11 are guided, and the four cylindrical pins 51 are fixed in the circular holes of the first cylinder movable plate 22 and the second cylinder movable plate 23 and the workbench fixed plate 11 at the same time. The second cylinder 31 moves upward, pushing the round shaft 32 and the sleeve 1 on the second cylinder 31 upward, and finally placing the top plate 52 on the cylindrical pin 51, using the hole on the top plate 52 and the cylindrical pin 51 and the sleeve 1 for horizontal limit, and opening the air pressure switch (the air pressure switch controls the third air pressure switch). Cylinder 41 moves), the third cylinder 41 is adjusted to the air intake and pressurized state, the top plate 52 and the sleeve 1 are fixed, and the vertical direction of the top plate 52 and the sleeve 1 is limited so that all components cannot move. After all the components are clamped, the connection between the top plate 52 and the sleeve 1, and the connection between the top plate 52 and the cylindrical pin 51 are welded from the upper surface through welding equipment, and the three are welded into a whole. Since the product components are clamped and fixed, the three will not be deformed or dislocated due to factors such as welding heat during the welding process, thereby ensuring the verticality of the product after welding and cooling. After the welding is fixed, the workbench 10 is adjusted to the pressure relief state through the air pressure switch, the first cylinder 21 contracts inward, the first cylinder movable plate 22 and the second cylinder movable plate 23 are separated from the workbench fixed plate 11, the second cylinder 31 moves downward, the round shaft 32 on the second cylinder 31 is loosened from the sleeve 1, the third cylinder 41 contracts downward, pulling the quick clamping arm 42 upward to lift the welded workpiece vertically upward.
