[0002] Metal welding fixture refers to the device for clamping and fixing metal workpieces during metal welding processing to prevent workpiece movement from affecting welding quality. The existing clamping device is uniformly circumferential clamping, which can only clamp regular-shaped articles and is difficult to clamp metal special-shaped parts. Moreover, the clamping force exerted by the existing clamping device on metal special-shaped parts is asymmetric force, which can generate certain torque and affect the stability of clamping. In addition, the clamping device needs to be disassembled and replaced for clamping different angle surfaces, which is low in production efficiency.
[0003] Prior art, for example, a kind of welding fixture for metal special-shaped part processing, authorization announcement number is CN113523702B. When the movable rod on one side of the same set of rings slides up and down, the movable rod on the other side slides in the opposite direction by the same distance, so that the two screw rods can always be connected in a straight line, so that the force of the top cap clamped in the object is always a pair of reaction force, increasing the stability of clamping.
[0004] At present, there is still a lack of a device that can conveniently clamp metal special-shaped parts, so that the two groups of electric push rods simultaneously contact the special-shaped parts, making the clamping of the special-shaped parts stable and facilitating subsequent processing.

By adopting the U-shaped rod passing through the guide plate, the lower electric push rod can only approach or move away from the metal special-shaped part.
