Auxiliary frame swing arm support welding positioning mechanism

According to the auxiliary frame swing arm support welding and positioning mechanism, the two positioning and clamping mechanisms are arranged to clamp the two swing arm supports, the two positioning and clamping mechanisms are pushed to slide through the pushing air cylinder to adjust the position, and the pushing air cylinder is movably connected with the two positioning and clamping mechanisms; the pushing air cylinder is also movably connected with the tool plate, so that the pushing air cylinder is good in flexibility and adaptability; and the clamping arms are limited through the middle limiting blocks during clamping, so that the product cannot be excessively clamped by the clamping heads, and when the clamping heads are clamped, the product can be accurately positioned by inserting the positioning pins into the positioning holes of the opening positioning blocks after penetrating through the passing holes of the product, and the welding accuracy is ensured. 本发明提供一种副车架摆臂支架焊接定位机构，通过设置两个定位夹紧机构来对两个摆臂支架进行夹
