The invention provides a welding gun positioning system, which comprises a welding gun inclination angle adjusting tool, a three-dimensional stepping motor driving device, a PLC (Programmable Logic Controller) control device and a touch screen, wherein the welding gun inclination angle adjusting tool is sleeved together with a welding gun, and is used for adjusting an included angle between the welding gun and the vertical direction, and reading the size and the direction of the included angle; the three-dimensional stepping motor driving device is fixedly connected with the welding gun inclination angle adjusting tool, and is used for driving the welding gun inclination angle adjusting tool to move and three-dimensional movement and accurate positioning of the welding gun is realized; the PLC control device is connected with the three-dimensional stepping motor driving device, and is used for determining the welding path of the welding gun and controlling the three-dimensional stepping motor driving device to move; and the touch screen is connected with the PLC control device, and is used for inputting welding path data. Due to the adoption of the welding gun positioning system provided by the invention, two welding poles can be positioned accurately, and the welding efficiency is increased.

Description

technical field [0001] The present application relates to the field of data positioning, in particular to a welding torch positioning system. Background technique [0002] During the welding process, the two poles of the arc formed by the base metal and the welding torch, the relative position between the tungsten electrode or the melting electrode and the weld seam are crucial to the stability of the arc, the quality of the weld seam and the fusion of the base metal and the added material. The position of the welding torch relative to the weld seam can be calibrated by the inclination angle of the welding torch, the initial coordinates and the walking route of the welding torch. Moderate wall spacing and included angles. Therefore, an efficient welding system should meet the requirements of quickly adjusting the coordinates and inclination of the welding torch, quickly positioning the welding torch and generating the welding path. The current tooling for adjusting the ori...

AI Technical Summary

Problems solved by technology

The current tooling for adjusting the position of the welding torch has the defects of complex structure, inconvenient operation and high production cost

The positioning methods between the two poles include unipolar motion and linkage. The latter is more common in multi-degree-of-freedom robots plus linkage rotation system, which is more complicated and expensive

Unipolar motion includes the method of fixing the welding torch or fixing the base metal. The method of moving the base metal by fixing the welding gun is not suitable for thick and large welding workpieces and working conditions with high requirements for welding positioning

[0003] The relatively simple manual arc welding has the disadvantages of poor stability and low welding efficiency, so it is only suitable for welding production operations with a small workload.
