Welding table of auxiliary frame of electric car

Abstract

The invention discloses a welding table of an auxiliary frame of an electric car, and relates to the technical field of electric car manufacturing. The welding table comprises a lower frame and an upper frame, wherein the lower frame is composed of longitudinal beams and transverse beams, and the upper frame is stacked above the lower frame and composed of longitudinal beams and transverse beams. The lower frame is at least provided with two supporting devices ejecting the upper frame. One ends of the supporting devices are hinged to the transverse beams of the lower frame, and the other ends of the supporting devices are hinged to the upper transverse beam of the upper frame. The two sides of the lower frame are provided with two or more pairs of upper hinge bases and lower hinge bases, the two sides of the upper frame are provided with two or more pairs of upper hinge bases and lower hinge bases, and the upper hinge bases and the lower hinge bases are hinged through movable pins. The left side and the right side of the upper frame are each provided with two or more fastening devices. The welding table can solve the problems that a current electric car auxiliary frame is low in welding efficiency, and the welding quality is not effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of electric vehicle manufacturing, in particular to a welding bench used for welding the auxiliary frame of the electric vehicle. Background technique [0002] Electric vehicle frames are generally divided into main frame and sub-frame. It is a flat plate on which some welding jigs or positioning plates are welded and fixed. After the sub-frame is assembled and welded, the welder needs to turn the sub-frame over when welding each weld seam. At the same time, in order to reduce the For welding deformation, it is necessary to temporarily fix the sub-frame with some simple pressure plates. In this way, some welding parts are not easy to weld, and the welder also needs to add a lot of unnecessary work for fixing the sub-frame, so that the welding efficiency is improved. At the same time, the welding quality cannot be guaranteed. Contents of the invention [0003] The purpose of the present invention is to pr...
