The second cylinder 113 and the third cylinder 114 are symmetrically arranged. When the second cylinder 113 and the third cylinder 114 are not working, the tightening assembly is positioned to the first threaded hole. When the second cylinder 113 is working and the third cylinder 114 is not working (the piston is not extended), it is positioned to the second threaded hole. When the second cylinder 113 and the third cylinder 114 are both working, they are positioned to the third threaded hole.

[0042] The second driving assembly is used to drive the second slide plate 110 to move, and includes: a fourth cylinder 115, a connecting plate 116, a push block 117, a first connecting rod 118, and a second connecting rod 119. The cylinder body of the fourth cylinder 115 is fixedly connected to the first slide plate 108. The connecting plate 116 is fixedly connected to the piston of the fourth cylinder 115. The two ends of the first connecting rod 118 are rotatably connected to the push block 117 and the second slide plate 110 on one side respectively. The two ends of the second connecting rod 119 are rotatably connected to the push block 117 and the second slide plate 110 on the other side respectively.

The fourth cylinder 115 pushes the connecting plate 116 to move, the movement of the connecting plate 116 drives the push block 117 to move, the movement of the push block 117 drives the first connecting rod 118 and the second connecting rod 119 to move, and drives the second slide plate 110 to move, so that the tightening assembly is positioned to the threaded hole.

[0043] The tightening assembly is used to tighten the screws. The tightening assembly is provided with two groups. The tightening assembly is respectively arranged on both sides of the first slide plate 108, including: a third guide rail 120, a third slide plate 121, a fifth cylinder 122, a first motor 123, and a first rotating shaft 124. The third guide rail 120 is vertically arranged and fixedly connected to the fixing frame 129. The third slide plate 121 is vertically slidably connected to the third guide rail 120. The cylinder body of the fifth cylinder 122 is fixedly connected to the fixing frame 129, and the piston of the fifth cylinder 122 is fixedly connected to the third slide plate 121. The first motor 123 is fixedly connected to the third slide plate 121. The first rotating shaft 124 is fixedly connected to the driving shaft of the first motor 123. One end of the first rotating shaft 124 is an outer hexagonal prism or a cross shape, which is arranged according to the shape of the nut groove and inserted into the nut groove of the screw. The second slide plate 110 is provided with a clearance hole 110a, through which the first motor 123 passes, and a gap is set between the first motor 123 to avoid interference between the first motor 123 and the second slide plate 110 when the first motor 123 moves up and down. The fifth cylinder 122 drives the third slide plate 121 to move, inserts the outer hexagonal column part of the first rotating shaft 124 into the nut, and then drives the first motor 123 to rotate, and then cooperates with the fifth cylinder 122 to descend, so as to tighten the screw without manual operation, which is more labor-saving.

[0044] The lifting assembly is used to drive the placement plate 103 to rise and fall, and includes: a sixth cylinder 125 and a first push plate 126.

Two placement plates 103 are provided, and the two placement plates 103 are respectively located at both ends of the first push plate 126. The sixth cylinder 125 drives the first push plate 126 to move, and the movement of the first push plate 126 drives the placement plate 103 to move, thereby leaving enough space to install the jack side plate 127 and the fixing block 128 on the placement plate 103.

[0045] Workflow: When the second cylinder 113 and the third cylinder 114 are not working, the tightening assembly is positioned to the first threaded hole. When the second cylinder 113 and the third cylinder 114 are working, they are positioned to the third threaded hole. When the second cylinder 113 is working and the third cylinder 114 is not working, the fourth cylinder 115 pushes the connecting plate 116 to move, the connecting plate 116 moves to drive the push block 117 to move, the push block 117 moves to drive the first connecting rod 118 and the second connecting rod 119 to move, and then drives the second slide plate 110 to move, so that the tightening assembly is positioned to the second threaded hole. Then the fifth cylinder 122 drives the third slide plate 121 to move, inserts the outer hexagonal prism part of the first rotating shaft 124 into the nut, and then drives the first motor 123 to rotate, and then cooperates with the fifth cylinder 122 to descend, so as to tighten the three screws, so that the jack side plate 127 is fixed to the fixing block 128, and there is no need to manually tighten each screw, which is more labor-saving and more convenient.
