Auxiliary frame swing arm support welding positioning mechanism

A movable sliding plate is arranged on a clamp base through a pushing mechanism, a clamping driving mechanism is arranged on the movable sliding plate, fixed connecting bases are symmetrically arranged on the front side of the clamping driving mechanism, supporting bases are symmetrically arranged on the front side of the clamp base, and rotating clamping arms are symmetrically arranged above the two sides of the fixed connecting bases; clamping blocks are symmetrically arranged at the front end of the rotating clamping arm, and a positioning support is arranged under the position between the clamping blocks. By designing the auxiliary positioning structure, the interval opening size of the swing arm support mounting structure is effectively guaranteed, the welding seam position consistency of the swing arm support is improved, the size stability and strength of parts are guaranteed, welding positioning is rapid and convenient, the labor intensity is reduced, the machining efficiency is improved, and meanwhil
