Rotary tower type batch laser shock welding device under vacuum environment

Abstract

The invention provides a rotary tower type batch laser shock welding device under a vacuum environment. The device comprises a computer control system, a laser generating system, a focusing lens cone, a vacuum system and a rotary tower type work platform. The laser generating system and the focusing lens cone form a laser source and a light path. The vacuum system comprises a vacuum chamber, a vacuum pump connected with an air pumping port of the vacuum chamber and a vacuum pump controller electrically connected with the vacuum pump, and a light transmitting hole is formed in the top face of the vacuum chamber. The rotary tower type work platform comprises a rotary base, a stepping motor driver connected with the rotary base, a rotary disc fixed on the rotary base and a plurality of clamps arranged on the rotary disc. The laser generating system, the vacuum pump controller and the stepping motor driver are electrically connected with a computer controlling system. By means of the device, small batch production of laser shock tiny connecting pieces under the vacuum environment is achieved, production efficiency is improved, effects of environment and manual operation on the welding quality are removed, and flexibility automatic inspection of laser shock welding process parameters is achieved.

Description

technical field [0001] The invention belongs to the field of laser shock welding, in particular to a turret type batch laser shock welding device in a vacuum environment. Background technique [0002] Laser impact welding machine is an emerging material welding technology under high-speed impact conditions. Its welding principle is similar to explosive welding and electromagnetic pulse welding. It uses two metal plates to collide at a high speed at a suitable angle. At the impact point, The stress generated by the impact greatly exceeds the yield stress of the metal, and the deformed metal joint surface will produce a jet. The spray gradually spreads along the bonding surface, cleaning the oxide layer on the surface, and leaving two cleaned bonding surfaces. High connection strength. [0003] Laser shock welding is generally used for relatively thin materials, generally 200 microns or thinner, and the diameter of the welding area is generally a few millimeters. It can real...

Problems solved by technology

[0006] Laser shock welding is an emerging high-speed shock welding technology. The research on many process parameters such as impact angle, flight distance, etc. is not perfect. Considering the influence of environment and human operation in the experimental process, an exploration of laser shock welding The automatic device of impact welding process parameters is particularly important; in addition, the existing laser impact welding is single-piece welding, which is extremely inefficient
