Description

Gap adjusting and positioning device for welding

Technical Field

The utility model relates to the field of welding technique, concretely relates to gap adjusting and positioning device for welding.

Background

During the welding process, the workpiece and the solder are melted to form a molten zone, and the molten pool is cooled and solidified to form the connection between the materials. In this process, pressure is also typically applied. The energy source for welding is widely varied and includes gas flame, electric arc, laser, electron beam, friction, ultrasonic, and the like. The only welding process was the metal forge welding continued by the carpenter for hundreds of years before the end of the 19 th century. The earliest modern welding techniques appeared at the end of the 19 th century, with arc and oxygen gas welding first, and later resistance welding. In the early 20 th century, with the first and second world war, there was a great need for inexpensive and reliable connection methods for military equipment, thus promoting the development of welding technology. Today, with the wide application of welding robots in industrial applications, researchers are still deeply researching the nature of welding and continuing to develop new welding methods to further improve the welding quality.

There are many ways of welding, and welding is one of them, and the joint formed when welding to connect two connected bodies is called a weld. When welding, the two sides of the weld joint are subjected to welding heat, and structural and performance changes occur, and the area is called a heat affected zone. During welding, the welding materials and the welding current are different according to the workpiece materials. The welding conditions need to be adjusted when the weldability is deteriorated, and the welding quality of the weldment can be improved by preheating the interface of the weldment before welding, preserving heat during welding and performing postweld heat treatment. In addition, welding is a local rapid heating and cooling process, a welding zone cannot expand and contract freely due to the constraint of the surrounding workpiece body, and welding stress and deformation are generated in a weldment after cooling, so that the adjustment of the size of a gap during welding is an important mode for eliminating the welding stress and correcting the welding deformation after welding.

In the existing butt welding operation process, when the gap between steel plates is adjusted, the gap is difficult to adjust in place, and long time is needed, so that the time of actual welding operation is influenced, the welding quality is also influenced, and the welding quality is improved in order to increase the time of the welding operation in the inherent time.
