Laser welding fixture

Technical Field

The utility model provides a laser welding fixture, and relates to the field of welding machine auxiliary equipment.

Background

Laser welding is a welding method that uses a high energy laser beam to join two or more workpieces together, and is a non-contact welding technique with a high degree of accuracy and control. During laser welding, a high energy laser beam is focused onto a small spot, creating a high temperature that melts and fuses the workpiece surface. The laser beam can be precisely controlled through optical elements such as optical fibers, lenses and the like so as to meet the requirements of different materials and applications. Laser welding is widely used in a variety of industries, such as automotive manufacturing, aerospace, electronics, and medical devices. It has obvious advantages in the aspects of welding tight connection, high quality, precise welding and the like. However, laser welding equipment is costly and requires some expertise and skill in operation and maintenance.

Laser welding can be classified into automatic welding and hand-held welding. Hand-held laser welding is suitable for small batches, complex shapes or welding tasks that are difficult to automate. In hand-held welding, an operator holds a laser welding gun and performs a welding operation by manually controlling the welding path and parameters. Hand-held welding has more flexible operability and can be adjusted and adapted to different workpieces, but also requires a certain welding skill and experience from the operator. For example, some workpieces need to be welded together by two thin plates with smaller sizes, the two thin plates are vertically or form a certain included angle, when in operation, an operator holds a welding gun with one hand, holds the thin plates to be erected with the other hand, the other thin plates are horizontally placed on a welding table, the operation table holds the thin plates to be erected by hand, so that the thin plates to be erected are kept in an upright state, then the other hand is used for welding, the welding skill of the operator is required, even in small-batch welding tasks, the operation is continued all the time, the labor intensity is very high, and the existing welding machine is matched with a clamp, but most of the welding machines are fixedly connected on a welding platform, so that the small thin plates to be erected cannot be well clamped and fixed.

To this end, we propose a laser welding jig.
