China's machinery manufacturing industry is in an industrial state of transformation and development. The industry's technical level is developing rapidly, production concentration is high, and market access is very large. Our company has advanced machinery manufacturing technology, a group of outstanding machinery manufacturing R&D personnel and perfect standardized quality supervision and management, and is committed to the globalization, networking, automation and green development of the machinery manufacturing industry. The engine bracket is a component used to fix the engine. One end of the engine bracket is fixedly connected to the engine, and the other end is connected to the engine mount fixed on the body, so as to fix the engine on the body. In the production process of the engine bracket, it is necessary to The engine bracket is welded, and the welding requires corresponding welding tooling to fix the bracket. However, during the use of the existing welding tool, the fixing of the engine bracket is not strong, and it is easy to shift during the welding process, which leads to poor subsequent welding accuracy. On the other hand, during the welding process, the lack of alignment The cleaning of the residue left on the side affects the subsequent use. The purpose of this utility model is to provide an engine bracket welding tool, which is simple and convenient to realize the effective fixation of the engine bracket, prevents poor welding precision due to poor fixation during the welding process, and at the same time, cleans the residue to solve the above problems. Issues raised in the background art.
