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.

Embodiment 1

[0031] Such as Figure 1 to Figure 6 As shown, a welding tool for electric tricycle assembly according to the present invention includes a tooling platform body 1; a group of fixing holes are evenly distributed on the top of the tooling platform body 1, and a pair of vertically arranged holes are fixed on the top of the tooling platform body 1 through bolts. The limit block 11; the top of the tooling table top block body 1 between the two limit blocks 11 is provided with a through groove 12, and the side of the tooling table body 1 is hinged with the corresponding position of the through groove 12. The U-shaped groove 15 has a cylinder 13 The end of the piston rod of the cylinder 13 is fixedly connected with a right-angled top block 14, and the side of the top block 14 near the through groove 12 is provided with a U-shaped groove 15; the bottom of the tooling table body 1 is provided with a jacking unit, The jacking unit and the corresponding position of the through groove 12 ...

Embodiment 2

[0040] Such as Figure 7 As shown, a slag discharge hole 55 is opened in the top block 14 on the side away from the cylinder 13 of the roller 52, and the side of the slag discharge hole 55 communicates with the cavity through an inclined surface 56, and the slag discharge hole 55 runs through the top block 14 and the slag discharge The hole 55 is arranged parallel to the axial direction of the roller 52, and an auger 58 is connected to the slag discharge hole 55 through the rotating shaft 57; the rotating shaft 57 and the roller 52 are driven by a figure-eight belt; 58 rotates, the welding slag scooped up by the cutter 53 on the top of the tooling table body 1 is discharged by the auger 58 after being transported by the inclined plane 56, reducing the residue of the welding slag at the cavity and increasing the efficiency of the cutter 53 to scrape the welding slag.

[0041] The bottom of the slag discharge hole 55 is provided with a set of return holes 6, the diameter of the ...

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 ...
