Description

Technical Field

[0002] With the continuous development of the machinery industry, the output of welded parts has increased year by year. In order to improve production efficiency and control product quality, special welding fixtures are required to clamp the welded parts to be processed for welding operations.

[0003] A welding fixture is a fixture that can ensure the size of the weldment, improve assembly accuracy and efficiency, and prevent the weldment from deforming. Most movable welding fixtures are equipped with universal wheels at the bottom and handrails at the top to facilitate the transfer of the welding fixture and improve welding efficiency.

[0004] However, the handrails of movable welding fixtures currently on the market are mostly fixed by welding, and the handrails cannot be disassembled after welding. In addition, in order to facilitate manual operation, the handrails have a higher structure that occupies a large space, which is not conducive to manual or machine welding operations on the weldments on the welding fixture, making the welding operation more difficult and increasing production costs.
