Driving and motor integrated handheld swing welding head

Abstract

The invention discloses a drive and motor integrated handheld swing welding head which comprises an outer shell of a gun handle-shaped structure. A laser head is mounted at the tail end of the outer shell; the open end of the outer shell is provided with a laser fiber connector. Laser is accessed from the laser fiber connector and is sent out from the laser head; a collimation optical system, an optical swing system and an optical focusing system are sequentially arranged in the outer shell in the light path direction of laser. The optical swing system is arranged at the turning position of the outer shell; according to the structure, modular arrangement is realized, and the collimation module, the reflection module, the focusing module, the protection module and the motor module are effectively combined into a whole; each module can be independently, simply and quickly disassembled; later use management is facilitated, the maintenance cost and the maintenance time of a user are reduced, production and popularization are more convenient, and popularization is more facilitated; and the integrated structure is extremely light and handy, so that an operator can use the device more conveniently and quickly.

Description

technical field [0001] The invention belongs to the technical field of laser welding, and relates to a hand-held swing welding head integrated with a drive and a motor. Background technique [0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology; in the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process is a heat conduction type, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the interior through heat conduction. By controlling parameters such as laser pulse width, energy, peak power and repetition frequency, the workpiece is melted to form a specific molten pool. Due to its unique advantages, it has been successfully applied in the precision welding of micro and small parts. [0003] Laser welding ...

AI Technical Summary

Problems solved by technology

[0004] However, the structure of the existing hand-held swing welding head on the market is relatively complex, the degree of modularization is poor, and the failure rate of the hand-held galvanometer welding head is very high. When the welding head fails, the existing hand-held galvanometer welding head must be equipped with a system Returning to the factory for maintenance is more difficult for the user to maintain, which in turn results in a higher cost for the user, making it difficult to popularize the hand-held swing welding head, so it is difficult to achieve the mass popularization of traditional welding in the market
