Welding tool for assembling electric tricycle

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of machining, in particular to a welding tool for assembling an electric tricycle. Background technique [0002] An electric tricycle is a three-wheeled vehicle that is powered by a battery and driven by a motor to pull goods or people. An electric tricycle mainly includes a frame, a motor, and a battery. The frame manufacturing process needs to go through blanking, welding, grinding, painting, and drying processes. During the welding process, welding tools are usually used to quickly fix the welded parts to improve The welding accuracy of the frame and the welding efficiency. [0003] There are also some technical solutions about welding fixtures in the prior art. For example, a Chinese patent with application number 201710199599X discloses a welding fixture, including a base, a platform, a lateral clamping device, a first side clamping device, a second The two-side clamping device and the cross clamping ...

AI Technical Summary

Problems solved by technology

[0006] In order to make up for the deficiencies of the existing technology, when splicing and welding the vehicle frame in the prior art, the steel pipe is first cut and blanked, and then the blanked steel pipe is placed on the tooling, clamped by the clamp and then passed through the welding equipment Butt welding is carried out on it, but due to the low cutting precision of the existing steel pipes during blanking, more burrs remain in the incision of the steel pipes after blanking, and at the same time, the alignment accuracy of the steel pipes is insufficient during butt welding, resulting in uneven weld seams, affecting Welding uniformity and welding quality, when the welding equipment supplies welding wire at a constant speed, the welding seam will form weld seams with different thicknesses with the moving speed of the welding machine, which will affect the automatic welding efficiency and welding quality of the frame.
