[0013] Compared with related technologies, the adjustment structure for welding fixtures of automotive parts provided by this utility model has the following beneficial effects: This utility model provides an adjustment structure for welding fixtures for automotive parts. By setting up a clamping assembly consisting of a support shell, a pad, an adjusting rod, a screw, a hydraulic cylinder, a pressure plate, and a pressure block, the hydraulic cylinder drives the pressure block to cooperate with the pad to clamp the workpiece. At the same time, the adjusting rod can finely adjust the height of the pad, so that the clamping assembly can be used for both ends of the workpiece with different thicknesses.

[0014] This utility model provides an adjustment structure for welding fixtures for automotive parts. By setting a support base at the bottom of the clamping assembly, the sliding column at the bottom of the support base can slide within the semi-circular groove of the operating table. In this way, the circumferential adjustment of the support base is achieved through the sliding cooperation between the semi-circular groove and the sliding column. With the precise insertion of the locking pin of the adjustment locking mechanism inside the support base into the slot on the operating table, it is ensured that the welding fixture is fixed in position without deviation. This allows for adaptive clamping and fixing of irregularly shaped workpieces. Attached Figure Description

[0020] Working principle: In use, first place the car part to be welded in the groove of the two support shells 7. Then adjust according to the thickness of the car part at both ends. Simply turn the adjusting rod 10 by the knob 11. The adjusting rod 10 moves axially through the threaded movement between the adjusting rod and the support shell 7, thereby moving the pad 9 until the car part is in a horizontal state. Then the hydraulic cylinder 12 moves the pressure plate 13 downward, so that the pressure block 14 on the pressure plate 13, together with the pad 9, clamps the car part. In addition, if the car part is not straight, simply push the pusher 65 by the button 66, so that the pusher 65 pushes the inclined block 61 and makes the locking pin 62 on the inclined block 61 disengage from the operating table 1, thereby releasing the restriction on the support seat 3. Then the support seat 3 slides in the semi-circular groove 101 on the operating table 1 through the sliding column 2 at its bottom to adjust the position until the clamping component above the support seat 3 corresponds to the bending angle of the car part. Then release the button 66. The locking pin 62 will be reset under the action of the spring 64 and re-inserted into the operating table 1 for fixation.
