Description

Technical Field

[0001] This utility model relates to the field of automotive workpiece processing technology, and in particular to a welding fixture for automotive workpieces. Background Technology

[0002] Automotive parts refer to components manufactured through processes such as machining, casting, and forging during automobile manufacturing. In the process of fixing the workpiece, the drive clamp is prone to damaging the fixed position of the workpiece when it comes into contact with the workpiece, thus affecting the fixing effect of the device.

[0003] The prior art CN220259982U discloses a welding fixture, including a welding plate, a first clamping assembly, a second clamping assembly, a cylinder, a pneumatic push rod, a second clamping plate, the first clamping plate, and a support spring. The workpiece is placed on the welding plate between the first and second clamping assemblies. The cylinder drives the pneumatic push rod to extend and retract, thereby moving the second clamping plate to abut against the workpiece. When the second clamping plate moves the workpiece closer to the first clamping assembly and contacts the first clamping plate, the support spring is compressed, which buffers the workpiece until the second clamping plate can no longer move forward, thus clamping the workpiece and preventing the clamping plate from damaging the fixed position of the workpiece, thereby improving the fixing effect of the device on the workpiece.

[0004] In normal use, due to the different specifications and dimensions of the workpieces, the existing technology cannot easily adjust the clamping force of the device when fixing workpieces of different specifications and dimensions. This can lead to deformation of the workpiece due to the clamping force, thus affecting the device's fixing effect on the workpiece. Utility Model Content

[0005] The purpose of this utility model is to provide a welding fixture for automotive workpieces, which solves the problem that, due to the different specifications and dimensions of the workpieces, the existing technology cannot easily adjust the clamping force of the device when fixing workpieces of different specifications and dimensions, which leads to the workpiece being deformed due to the clamping force, thus affecting the fixing effect of the device on the workpiece.

[0006] To achieve the above objectives, this utility model provides a welding fixture for automotive workpieces, including a base and structural components.

The vertical block's movement moves a frame, allowing adjustment of the frame's displacement. A displacement motor drives a displacement screw to rotate. When the displacement screw rotates, it drives a vertical block to move on the vertical block. The vertical block drives a drive cylinder to move a fixed block, allowing adjustment of the fixed block's position and height. The adjustment motor drives...
