[0057] The transverse clamping member 416 includes a transverse clamping block 4161, a second clamping motor 4162, a transmission rack 4163 and a driving gear 4164.

The transmission rack 4163 is fixedly connected to the transverse clamping block 4161, and the two sets of transmission racks 4163 are respectively meshed with the two sides of the driving gear 4164.

[0058] Working principle: When the device is in use, first place the back plate of the power supply cabinet on the top of the rotating support 421, and then put the side frame of the power supply cabinet on the top outer surface of the back plate, then start the first clamping motor 412 through the control cabinet 2 to make the bidirectional screw rod 413 rotate, and then the two groups of triangular clamps 411 move toward the middle along the slide groove 101, and finally make the two groups of triangular clamps 411 limit the left and right positions of the workpiece, and then start the second clamping motor 4162, so that the driving gear 4164 drives the two groups of transmission racks 4163 to move, so that the lateral clamping blocks 4161 on both sides move toward the middle, thereby limiting the front and rear positions of the workpiece, and finally make the two groups of triangular clamps 411 and four groups of lateral clamping blocks 4161 clamp the workpiece at the top center position of the welding table 1;

[0059] At this time, the sliding seat 61 is in the middle position of the horizontal slide rail 321. First, the lifting drive motor 313 is started to make the lifting support 312 descend, so that the argon arc welding assembly 6 enters the cabinet. Then, the horizontal drive motor 322 is started to make the sliding seat 61 slide horizontally to one side along the horizontal slide rail 321 and contact one side of the inner wall of the cabinet. At this time, the electric telescopic rod 610 is started to make the end of the welding head 64 face the connection between the back plate and the side frame. At this time, the wire feeder 65 and the solenoid valve 7 are energized to complete the preparation work before welding.

[0060] Then the horizontal driving motor 322 is started to rotate at a constant speed. At this time, the sliding seat 61 is driven by the horizontal driving screw 323 to slide slowly along the horizontal slide rail 321. During the sliding process, the arc block 682 at the bottom of the sliding seat 61 moves along the welding protrusion 692 and the circuit breaker groove 693 at the bottom of the welding guide strip 69. When the arc block 682 moves to the surface of the welding protrusion 692, the welding protrusion 692 presses the push rod 681 downward, so that the pressure plate 683 presses the spring switch 61. 2. At this time, the solenoid valve 7 and the wire feeder 65 are started, and the welding wire and argon gas are fed into the welding head 64. At the same time, as the push rod 681 moves downward, the semicircular block 684 at its bottom pushes the protrusions 685 on both sides outward, so that the electric telescopic rod 610 drives the welding head 64 to move outward. At the same time, the reset spring 687 is compressed, so that the welding head 64 contacts the inner wall of the power supply cabinet. At this time, as the sliding seat 61 moves, welding is performed to form a weld, and the length of the weld is equal to the length of the welding protrusion 692.

[0061] When the arc block 682 moves to the position of the circuit-breaking groove 693, the reset spring 687 pushes the two sets of electric telescopic rods 610 toward the middle, so that the welding head 64 is not in contact with the inner wall of the cabinet. At the same time, the protrusion 685 at the end of the electric telescopic rod 610 pushes the semicircular block 684 upward, so that the lower pressing rod 681 moves upward, and at the same time, the pressure plate 683 moves upward from the top of the spring switch 612, and the spring switch 612 automatically resets to realize the circuit breaking of the solenoid valve 7 and the wire feeder 65. At this time, as the sliding seat 61 moves, the welding head 64 does not perform the welding operation, and waits to move to the next set of welding protrusions 692 for connection again. Touch welding, and the distance between two adjacent groups of welds is equal to the length of the disconnecting groove 693. By accurately setting the welding protrusion 692 and the disconnecting groove 693 on the surface of the welding guide bar 69, the welding head 64 can be driven by the horizontal driving motor 322 to move at a uniform speed, and automatic welding can be achieved during the movement. It can ensure that the weld length and weld spacing fully meet the standards, which solves the problems of low efficiency, high risk and uneven welding quality in traditional manual welding. At the same time, compared with high-end laser welding machines, it has lower costs and is more suitable for welding processing of low-end equipment such as power supply cabinets;

[0062] After welding is completed on the front and back sides inside the cabinet, the lifting drive motor 313 drives the lifting pillar 312 to move upward, and then the first clamping motor 412 and the second clamping motor 4162 rotate in the opposite direction, so that the two groups of triangular clamps 411 and the four groups of horizontal clamps 4161 are moved away from the surface of the workpiece. At this time, the rotating motor 422 is started, and the rotating support 421 is driven to rotate through the transmission chain 423, thereby driving the workpiece on its top to rotate 180 degrees. At this time, the workpiece is clamped again by the workpiece clamping member 41, and then the argon arc welding assembly 6 is driven to move down to the inside of the cabinet through the driving bracket 3 to perform welding operations on the other two side edges of the cabinet. No manual operation is required, and it is fast and safe.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
