Intelligent electric arc welding gun device, arc striking method and arc length compensation adjusting method

Abstract

The invention provides an intelligent arc welding gun device, an arc striking method and an arc length compensation adjusting method. A second stepping motor is arranged on a grip; a telescopic mechanism is arranged between the second stepping motor and a welding rod; one end of the telescopic mechanism is connected with the second stepping motor, and the other end of the telescopic mechanism is connected with the welding rod; a motor shaft of the second stepping motor is fixedly connected with a magnetic grid disc sleeve; the magnetic grid disc sleeve is fixed on a telescopic mechanism shell in a sleeved mode; a telescopic rod is controlled by a control system and stretches out and retracts in a square guide rail; a rotary threaded rod is arranged at the rear end of the telescopic rod and inserted into a hollow sleeve at the front end of the magnetic grid disc sleeve; and a first stepping motor drives the rotary threaded rod to do spiral motion through the control system. According to an intelligent auxiliary manual arc welding gun device suitable for all positions of the invention, the technical difficulties that in the background technology, arc striking is difficult, arc length control is difficult, and electric arc swing is difficult to operate can be overcome, the skill requirement of manual arc welding for an operator is lowered, the welding quality of manual arc welding is improved, and the comprehensive cost of manual arc welding is lowered.

Description

technical field [0001] The invention belongs to the field of arc welding torches, and relates to an intelligent arc welding torch device, an arc starting method and an arc length compensation adjustment method. Background technique [0002] As a widely used welding method, manual arc welding still plays an important role in all walks of life in the development of the national economy. Traditional manual arc welding tongs requires high skills in operation, especially for beginners, there are often technical difficulties such as easy sticking of electrodes and difficulty in arc ignition; manual arc stabilization operation is difficult, arc length changes greatly; arc swing operation is difficult and other technical difficulties. The welding quality of traditional manual arc welding has a high level of skill for operators, and it is difficult to train and learn. Poor welding quality and long training time bring about high cost of manual arc welding. [0003] The application da...

Problems solved by technology

Traditional manual arc welding tongs requires high skill in operation, especially for beginners, there are often technical difficulties such as easy sticking to the electrode and difficult arc ignition; manual arc stabilization operation is difficult, arc length changes greatly; arc swing operation is difficult and other technical difficulties

The welding quality of traditional manual arc welding is relatively high for operators, and the training and learning are difficult. Poor welding quality and long training time bring about high cost of manual arc welding.

[0003] The application date is June 1, 2020, the application number is 2020104825456, and the patent name is "A self-oscillating arc welding torch device and assembly method", which discloses a self-oscillating arc welding torch to realize the manual arc welding process While the medium arc swings on its own, it can keep the arc swing radius unchanged in the single-pass welding process without special algorithms, and can adapt to various spatial positions and electrode inclinations in a wide range, and has no influence on the arc center position and swing frequency. The detection adapts to more environments, but it also relies on manual work and experience for arc ignition, which also requires high operator skills, and cannot realize the arc length compensation adjustment function in the welding process
