Description

Technical Field

[0001] The utility model relates to arc welding equipment, and more specifically to a laser positioning insulation device applied to a hot wire-TIG automatic welding system. Background Art

[0002] Welding is one of the important links in modern manufacturing. Arc welding is currently the most widely used. Among them, non-melting electrode gas shielded welding (TIG) has the advantages of stable arc, good welding airtightness, less pores, and high welding quality. It is widely used in welding in pipelines, shipbuilding, military industry and other fields. However, when facing the welding of some complex components, the welding track is relatively complicated, and manual teaching and positioning is time-consuming and labor-intensive, which is cumbersome and cannot achieve fully automated welding. Weld seam laser positioning technology can automatically identify welds through laser sensing, locate and teach welding points, and has the advantages of high precision, high efficiency and high reliability. It has strong adaptability in complex component welding and repetitive work, and is one of the key technologies for realizing automated welding and intelligent welding. However, since TIG welding uses a high-frequency oscillator to generate high frequency for arc initiation and arc stabilization, there is a high-frequency oscillation voltage throughout the welding process, which will cause serious interference to the electronic circuits in the working environment through conduction and coupling. Therefore, the high frequency generated in TIG welding will interfere with and damage equipment such as laser positioning cameras, making it difficult to apply laser positioning technology to TIG welding.

In this mode, the camera positioning range is large and the robot accessibility is high.

[0008] (2) Both the connector and the conversion part are made of aluminum alloy, which is light in weight and high in strength. They are provided with threaded holes at different positions for connecting with the camera, so that the relative position of the camera and the welding gun can be adjusted to meet the welding requirements in different situations.
