[0041] The bottom plate 1 is fixed to the ground by ground bolts, and the table plates 3 on both sides are supported between two driving devices 2, and each table plate 3 is driven by a driving device 2. The angles of the two table plates 3 are independently adjustable, and can be adaptively adjusted according to the welding angle requirements of the two plates.

[0059] In the above technical solution, during the sliding and pushing process of the slide 41, the guide wheel 445 rolls along the guide inclined surface 3233, so that the upper clamping plate 443 moves downward, thereby completing the clamping of the welded plate.

[0060] By driving a single servo motor, the sliding of the slide table 41 is achieved, and the passive movement of the upper clamping plate 443 is achieved, saving the cost of installing another clamping motor.

[0061] See also Figure 7 As shown, an anti-slip sheet 44443 made of elastic rubber material is glued and fixed to the bottom of the upper clamping plate 443.
