Abstract

The utility model provides a workpiece welding fixture, which is characterized in that a connecting column to be processed is placed between a clamping block and a limiting carrier plate. The driving air cylinder drives the bearing plate to move close to the clamping block through the driving plate, and the connecting column to be processed is clamped and fixed. On the other hand, the rotating cylinder drives the L-shaped clamping rod to rotate so as to combine the limiting carrier plate to longitudinally limit the connecting column to be processed. By utilizing the principle of a screw rod, the driving motor drives the driving block to drive the bearing plate to move along the sliding track through driving the screw rod. The bearing plate drives the connecting columns to be processed to be connected together end to end through the clamping assemblies. And an external welding robot or a welder welds the head-to-tail connected parts of each connecting column to be processed together. The external rotating motor drives the receiving frame to rotate through the connecting column at one end of the receiving frame, and the receiving frame rotates to reversely rotate each connecting column to be processed through each clamping assembly so as to facilitate the welding of the other surface by an external welding robot or a welding worker.
