Vehicle body mortise-and-tenon-joint-structure welding transfer vehicle

Abstract

The invention provides a vehicle body mortise-and-tenon-joint-structure welding transfer vehicle, belongs to the technical field of welding processes, and aims at solving the problems that existing welding processes are all traditional groove welding, grooves need to be formed in parts when surface appearance parts are welded, the operation process is troublesome, a vehicle body overall frameworkis inconvenient, weld joints can occur after welding is completed, and the surface appearance is affected. The vehicle body mortise and tenon joint structure welding transfer vehicle comprises a vehicle body plate, wherein a base is arranged on the vehicle body plate. According to the vehicle body mortise-and-tenon-joint-structure welding transfer vehicle provided by the invention, due to the facts that a second inner clamping type groove is formed in a connecting plate, base protruding ends are arranged at the front end and the rear end of the base, and the base protruding ends are matched with first inner clamping type grooves, and the first inner clamping type grooves and the base protruding ends are arranged, so that parts can be conveniently fixed through a mortise-and-tenon joint structure during mortise-and-tenon connection; and meanwhile, the parts are welded after being spliced, and no weld joint is left on the appearance aspect after simple polishing is conducted after welding is completed, so that surface seamless welding can be achieved.

Description

technical field [0001] The invention belongs to the technical field of welding technology, and more specifically relates to a body mortise and tenon structure welding transfer vehicle. Background technique [0002] Among the more and more welding workpieces, there are many workpieces that have high requirements on size. In the past, the difference in welding process was only based on the different parts and different sizes, which required high welding requirements. Through various tests and various research and development, we developed A positioning welding process capable of rapid splicing. Through laser cutting, it will need to be positioned, and the plane with high size requirements will be cut and formed. After the splicing is completed, the size will be checked and the parts will be welded. This process is mainly for appearance parts or very demanding welding surfaces. Grinding can achieve seamless welding, which can greatly improve the welding strength and welding qu...

Problems solved by technology

[0006] In order to solve the above technical problems, the present invention provides a car body mortise and tenon structure welding transfer vehicle to solve the problem that the current welding process is traditional groove welding. When welding surface appearance parts, it is necessary to make grooves on the parts, and the operation process is troublesome. , it is not convenient for the overall structure of the body, and there will be weld seams after the welding is completed, which will affect the appearance of the surface
