Welding device and welding method for automobile welding assembly line

Abstract

The invention belongs to the technical field of automobile welding, and discloses an automobile welding assembly line welding device which comprises a bottom plate, a power fixing frame is fixedly installed at the rear end of the top of the bottom plate, two sliding supporting seats are fixedly installed at the front end of the top of the bottom plate, and the middles of the two sliding supporting seats are movably sleeved with second sliding rods. Limiting frames are fixedly welded to the inner sides of the two second sliding rods. The purposes of high-adaptability welding and low cost are achieved by arranging the power guiding device, the power driving device, the second sliding rod and other structures to work in a matched mode, in this way, a traditional mechanical arm structure can be well replaced, the manufacturing cost is greatly reduced, the power guiding device and the power driving device work in a matched mode in different styles, and the welding efficiency is improved. And finally, it can be guaranteed that the welding head can complete curved surface welding, meanwhile, richer and more-level welding requirements can be met, the production and manufacturing cost is greatly reduced, and the welding head can also serve as an alternative scheme of a simple automobile assembly line.

Description

technical field [0001] The invention belongs to the technical field of automobile welding, in particular to a welding device and a welding method of an automobile welding assembly line. Background technique [0002] The automobile welding production line is mainly body-in-white welding, which is composed of the body frame, engine cover, trunk lid, left and right door outer panel welding assembly. The car body skeleton structure is composed of floor welding assembly, left and right front longitudinal beam and wheel house welding assembly, left and right side wall welding assembly, front wall welding assembly, roof and front and rear beams, tailgate, left and right rear longitudinal beams And the welding assembly of the rear wheel cover, and the welding assembly of the rear wall. Welding is a necessary process in modern machinery manufacturing, and it is widely used in automobile manufacturing. With the advancement of technology, new welding processes, new materials, and new...

AI Technical Summary

Problems solved by technology

[0003] The existing automobile production line is relatively complete as a whole, and it is a better processing method in automobile production and processing. However, the whole set of equipment is often expensive, and it is difficult to use the entire industry chain. The main improvement of this application is the traditional automobile Welding method, the existing automobile welding method is mainly divided into two parts: manual processing and mechanical processing. Manual is the most common hand-held device and then finds the corresponding area for welding processing. Although this operation method can be liberalized, it depends on the situation. Changing the work problem, but automobile production belongs to the work of the assembly line of a large factory, and long-term work cannot be done by humans; on the other hand, it is mechanical welding. Mechanical welding is divided into two categories: fixed machinery and multi-degree-of-freedom robotic arms. The welding area of ​​the plane is processed, which is subject to many external environments, and the working range is also very limited, so the practical range is not wide. On the other hand, it is the mechanical arm, which can realize the multi-mechanism of the car through the preset program. Multi-region welding, but the system structure of this device is very large, and the manufacturing cost is high, and the follow-up maintenance is also very troublesome, so there are still many immature areas in the existing processing of this aspect
