The invention belongs to the technical field of
machining, and particularly relates to a
welding tool for assembling an electric tricycle. The
welding tool for assembling the electric tricycle comprises a tool bench body, a set of fixing holes are evenly distributed in the top of the tool bench body, and a pair of vertically-arranged limiting blocks are fixedly connected to the top of the tool bench body through bolts; a through groove is formed in the portion, between the two limiting blocks, of the top of the tool bench body, and an air cylinder is hinged to the position, corresponding to the through groove, of one side of the tool bench body; a right-angle ejector block is fixedly connected to the end of a
piston rod of the air cylinder, and a U-shaped groove is formed in the side, close to the through groove, of the ejector block; and a jacking unit is arranged at the bottom of the tool bench body, a
grinding disc is rotationally connected to the position, corresponding to the through groove, of the jacking unit, and the
grinding disc penetrates through the through groove and extends to the top of the tool bench body. According to the
welding tool for assembling the electric tricycle, the
grinding disc is driven by the jacking unit to ascend to
grind a notch of a steel
pipe, the flatness of the notch is improved, the alignment error of the steel
pipe is eliminated, and the automatic efficiency of frame welding is improved.
