Integration welding gun with optical spectrum detecting device installed externally

Abstract

The invention discloses an integration welding gun with an optical spectrum detecting device installed externally and belongs to the field of welding equipment and processes. The integration welding gun with the optical spectrum detecting device installed externally comprises an upper shell body, a cooling and protective system, a tungsten electrode regulating system, a lower shell body, a jet, a tungsten electrode and an optical spectrum detecting system. The tungsten electrode regulating system which is arranged on the lower shell body increases catching ranges of weld joints, conducts online detection of welding processes timely, analyzes forms of weld joint failure accurately, adjusts welding parameters, and guarantees weld joints with high quality. The tungsten electrode regulating system is arranged inside the cooling and protective system, one section of a regulating button stretches out of the outside of the lower shell body, and stretching out length of the tungsten electrode is convenient to adjust by pressing the regulating button from the outside. A cooling water chamber is integrated with an air chamber, thus increasing the size and improving cooling effects. A plurality of air holes are formed in a gas wall, so shielding gases blow over two sides of the tungsten electrode, thus protecting welding arcs, stabilizing electric arcs, and improving welding quality.

Problems solved by technology

[0002] As a manufacturing technology, welding is widely used in various industries. Welding joints are generally the weakest parts of components. Therefore, the quality of welding largely determines the quality and pass rate of products. Therefore, it is essential to monitor the welding process. However, the general monitoring device can only observe the shape of the weld to judge whether the welding has failed, but can not find out what caused the failure. Therefore, online spectral detection of the welding process becomes a specific analysis and real-time correction Welding parameters for high quality welds

[0003] At present, there are existing technologies in the field of automatic welding with an online spectrum detection system, such as: the application number is 201010110465.4, and the publication number is CN101774064A "Automatic welding machine arc light detection intelligent tracking system"-provides an automatic welding machine arc light intelligent tracking system, It belongs to the field of welding technology; it solves the problem that the distance between the existing automatic welding torch and the welding seam will change, resulting in differences in the welding effect of each point on the welding seam and poor welding quality; structurally speaking, the welding torch is installed on the A visual device independent of the welding torch, with a special installation structure, resulting in too large a volume, taking up too much space, not compact enough, and easily causing interference or even collision with the working environment, affecting the accessibility of the welding torch; at the same time, the installed visual The device is only located on one side of the welding torch, and cannot capture the changes on both sides of the weld well during welding, which has a certain impact on the analysis of weld quality; the application number is 201210030180.9 "a coaxial integrated with visual function Welding gun" provides a device for monitoring the quality of the weld with a camera. This device uses the camera to capture the weld and judges the quality of the weld through the shape of the weld on the computer. Therefore, this method cannot well point out the main cause of weld failure. Influencing factors, it cannot provide a strong basis for future welding, and cannot fundamentally guarantee high-quality welds
