A welding tool for electric tricycle assembly

Abstract

The invention belongs to the technical field of mechanical processing, and specifically relates to a welding tool for electric tricycle assembly, including a tooling platform body; a group of fixing holes are evenly distributed on the top of the tooling platform body, and a pair of vertically arranged welding tools are fixed on the top of the tooling platform body through bolts. Limiting block; the top of the tooling table body between the two limiting blocks is provided with a through groove, and a cylinder is hinged on one side of the tooling table body corresponding to the through groove; the end of the piston rod of the cylinder is fixedly connected with a right-angled top block, There is a U-shaped groove on the side of the top block close to the through groove; the bottom of the tooling table body is equipped with a jacking unit, and the lifting unit is rotatably connected to the corresponding position of the through groove with a grinding disc, which runs through the through groove and extends to the top of the tooling table body The present invention drives the grinding disc to rise through the jacking unit to grind the incision of the steel pipe to increase the flatness of the incision, eliminate the alignment error of the steel pipe, and improve the automation efficiency of the frame welding.

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.
