Abstract

The invention discloses a welder for an automotive door bumper. The welder comprises two welding gun intermediate connection seats which are arranged on transversely arranged guide rails and driven by screw rods. The screw rods respectively driving the two welding gun intermediate connection seats rotate in opposite directions, and are connected with the same power transmission mechanism. A welding gun mounting frame driven by an oil cylinder is arranged on each of the welding gun intermediate connection seats through a longitudinally arranged guide rail. Two welding guns are arranged on each of the welding gun mounting frames. A fixture table of the automotive door bumper is arranged below the welding guns. Compared with the prior art, the welder can solve the problems of low consistency of a plurality of weld joints of the conventional automotive door bumper and deformation of a welded workpiece.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a device for welding an automobile door anti-collision bar. Background technique [0002] At present, an existing automobile door anti-collision bar is made of a circular steel pipe welded in a groove connecting a supporting plate at its two ends. The welding seam between the circular steel pipe of the car door anti-collision bar and each connecting plate is located on both sides of the connection between the circular steel pipe and the groove of the connecting plate. There are 4 welds between the circular steel pipe and the two connecting plates. The four welds are parallel to each other and every two are arranged symmetrically. In order to ensure that it is accurately installed on the set position of the automobile door during use, the relative position accuracy of the connecting brackets at both ends of the automobile door anti-collision bar is required to be v...
