[0023] Working principle:

[0024] When welding automobile parts, the two parts to be welded are placed between the clamping plates 12 on both sides, the external power supply of the hydraulic cylinders 10 on both sides is turned on, and the telescopic ends of the hydraulic cylinders 10 on both sides are started to shorten to drive the transmission plates 11 on both sides to move. The transmission plates 11 on both sides can drive the four transmission arms 13 on both sides to move, so that the transmission arms 13 on both sides can pull the clamping plates 12 on both sides to move, so that the four groups of clamping plates 12 on both sides can clamp and fix the two parts, and the operator can perform the welding operation.

[0025] Adjustment process:

[0026] When it is necessary to adjust the position of the parts, the external power supply of the motor 201 is connected, and the output shaft of the motor 201 is started to rotate to drive the stud 203 to rotate. The rotation of the stud 203 can drive the threaded blocks 202 on both sides to move, and the threaded blocks 202 on both sides can drive the push rods 204 on both sides to move, so that the push rods 204 on both sides can drive the cross plate 206 to rise and fall through the connecting blocks 205 on both sides. The lifting and lowering of the cross plate 206 can drive the rotating rods 9 on both sides to rise and fall synchronously through the rotating shaft plates 3 on both sides. The movement of the rotating rods 9 on both sides can drive the sliders 4 and the clamping boxes 5 on both sides to move synchronously, so that the height position of the workpiece can be adjusted.

[0027] Angle adjustment process:

[0028] The operator can rotate the handle 802 clockwise so that the handle 802 can drive the ratchet 804 and the rotating rod 9 to rotate clockwise through the straight rod 805. Under the action of the pawl 808, the ratchet 804 can be restricted from rotating counterclockwise, so that the clamping box 5 can rotate. When it is necessary to rotate the clamping box 5 counterclockwise, the operator pulls the pull rod 806 through the ring 807 to move the pull rod 806, so that the pull rod 806 can drive the pawl 808 to rotate, so that the pawl 808 is no longer engaged with the surface of the ratchet 804, so that the clamping box 5 can rotate counterclockwise, and loosen the ring 807. Under the action of the spring 809, the pawl 808 can be pushed back to its original position.
