High-precision three-axis laser welding equipment

Abstract

The invention discloses high-precision three-axis laser welding equipment, and the equipment comprises a base, a stand column frame, an X-axis driving device, a Y-axis driving device, a Z-axis drivingdevice, a laser welding head, a welding head angle adjusting mechanism and a working platform. The bottom of the stand column frame and the bottom of the working platform are both fixed to the base.The X-axis driving device, the Y-axis driving device, the Z-axis driving device and the welding head angle adjusting mechanism which are connected in sequence are installed at the top of the stand column frame. The laser welding head is installed on the welding head angle adjusting mechanism, so the angle adjustment of the laser welding head is achieved through the welding head angle adjusting mechanism. According to the invention, the laser welding head can accurately move to any point in a three-dimensional space; and meanwhile, by adjusting the angle of the laser welding head and the heightof the working platform, the high-quality welding of high-reflectivity materials such as aluminum alloy can be achieved, and the welding of workpieces of various complex shapes can also be achieved.

Description

technical field [0001] The invention relates to the technical field of laser processing equipment, in particular to a high-precision three-axis laser welding equipment. Background technique [0002] With the rapid development of the industrial laser industry, the market's requirements for laser processing technology are getting higher and higher, and the application of laser technology is becoming more and more diversified.

AI Technical Summary

Problems solved by technology

[0003] When laser welding machine tools are used to weld workpieces such as thin plates, the butt weld seam is extremely small, so the laser welding equipment itself is required to have high precision; , most of the laser light is reflected back into the mirror group after being directly irradiated, which may cause damage to key components such as the lens, and affect welding performance and welding quality; therefore, it is necessary to design a mechanism to adjust the incident angle of the laser beam at the laser welding head
