Welding is an important manufacturing method. The deformation caused by this processing method will seriously affect the structural strength of the thin plate itself.

[0003] For example, an aluminum alloy thin plate welding device with authorization announcement number "CN216541543U" is clamped by a clamping head, and its position relative to the aluminum alloy thin plate is adjusted by the action of a transverse moving part, a longitudinal moving part and a rotating part, and finally the two are welded by a welding part, thereby improving the welding effect and welding accuracy, and reducing the processor's need to only move the slider to adjust the position of the welding gun, making the processing easier. However, when the device clamps and fixes the thin plate for welding by a clamping head, it is easy to cause the thin plate to deform, resulting in thin plate welding failure, and reducing the accuracy of the thin plate welding of the device. The device requires the operator to manually control the adjustment bolt to adjust the position of the clamp arm and the slide slot, which increases the operator's workload, reduces the workload of the device, and reduces the working efficiency of the device.

[0027] Working principle:

[0028] Fixed clamping process during thin plate welding:

[0029] After the operator places the two thin plates on the surface of the load-bearing platform 12 and docks them, the operator turns on the external power supply of the first motor 201, starts the output shaft of the first motor 201 to rotate and drive the stud 202 to rotate, and the stud 202 rotates to drive the two threaded blocks 203 to move in opposite directions.

When the clamping block 207 is pressed against the surfaces of the two thin plates, the output shaft of the first motor 201 is stopped from rotating, and the two thin plates are fixedly clamped. The operator controls the welding gun 11 to weld the thin plates. After the welding is completed, according to the above operation, when it is no longer necessary to fix and clamp the thin plates, the output shaft of the first motor 201 is started again to reverse and drive the clamping arm 206 and the clamping block 207 to rise, so that the operator can take out the welded thin plates and complete the fixed clamping process of the thin plate welding.

[0030] Auxiliary welding process of thin plates:

[0031] The operator first connects the external power supply of the welding gun 11 and the hydraulic cylinder 9, starts the telescopic end of the hydraulic cylinder 9 to extend, drives the welding gun 11 on the surface of the slider 10 to a suitable position, and then starts the external power supply of the second motor 301, starts the output shaft of the second motor 301 to rotate and drives the worm 303 to rotate, the rotation of the worm 303 drives the worm wheel 304 to rotate, the rotation of the worm wheel 304 drives the rotating drum 305 to rotate synchronously, the rotating drum 305 drives the spring rod 307 to move, the spring rod 307 drives the support rod 7 to move horizontally, the support rod 7 drives the welding gun 11 to move, the spring rod 307 compresses the spring 306 when it rotates, and the spring rod 307 retracts into the rotating drum 305, leaving movement space for the support rod 7 to move horizontally, thereby completing the auxiliary welding process of the thin plate.
