[0053] In the present utility model, after the lifting component 8 lifts the transformer cover, the horizontal limit moving component 4 moves to the specified position to accurately limit the side of the transformer cover, and then the horizontal clamping component 5 moves to clamp the transformer cover horizontally and firmly. Similarly, the longitudinal limit component 6 and the longitudinal clamping component 7 cooperate to longitudinally position and clamp the transformer cover firmly.

Finally, the welding robot 1 is used to complete the welding of various components on the transformer cover in the appropriate position, thereby improving the welding efficiency.

[0054] like Figure 1 、 Figure 2 As shown, in some embodiments, the base assembly 2 includes a mounting plate 10, which can be made of a steel plate. The mounting plate 10 is mounted on the base plate 3 through a support rod. The mounting plate 10 is provided with a transverse groove 11 and a longitudinal groove 12, which are used to install various components.

[0055] The transverse limiting assembly 4 includes a transverse limiting electric cylinder 13, which is specifically installed in the transverse groove 11 or the longitudinal groove 12. The output end of the transverse limiting electric cylinder 13 is connected to a first transverse clamp 14 via a connecting rod. The first transverse clamp 14 is quickly removable, facilitating replacement of different first transverse clamps 14 according to different transformer cover sizes. The transverse limiting electric cylinder 13 is electrically connected to a control device (not shown), which can be a PLC controller or a control circuit board.

[0061] In the utility model, a welding robot 1 is arranged in the center and the clamping platforms are arranged symmetrically on both sides. In order to prevent the transformer box cover from being deformed during welding, the box cover is welded in two sequences. First, the tooling is manually adjusted according to the product model, and the tooling is clamped to perform spot installation and welding on one side of the box cover. Then, the tooling is manually lifted to another tooling platform by KBK, and the other side is clamped and welded. This minimizes the welding deformation of the box cover. The double workstations serve as backup for each other, so that the robot is always in a welding state, and the welding efficiency is high.
