Description

Swinging type contact positioning mechanism for automatic feeding of pipe fitting Technical Field The utility model relates to the technical field of pipe fitting machining, in particular to a swinging type contact positioning mechanism for automatic feeding of pipe fittings. Background The electric vehicle frame is formed by welding a large number of pipe fittings, and in the pipe fitting machining process, automatic feeding of the pipe fittings is required to be realized in order to improve the machining efficiency of the pipe fittings. An automatic pipe fitting feeding system is used at present, which is to firstly stack pipe fittings in a material box in a scattered way, a multi-stage lifting table is arranged in the material box, the table surface of the lifting table is inclined, when the lifting table is lifted, the pipe fitting is transported upwards step by step, so that the pipe fitting is transported to the conveyor belt, and the length direction of the pipe fitting is consistent with the length direction of the conveyor belt.
