Abstract
Description
Technical Field
[0001] This utility model relates to a welding equipment, specifically a welding torch device for a linear coordinate welding equipment, and belongs to the field of welding technology. Background Technology
[0002] Welding equipment on the market is divided into linear coordinate welding equipment and articulated welding equipment. Linear coordinate welding equipment is widely used. This type of equipment generally includes CNC driven X, Y, and Z axes, with an A-axis installed at the end of the Z-axis. The A-axis is a rotary axis. When using this type of welding equipment, it is difficult to install anti-collision devices on the welding torch. In addition, because power cables, signal cables, and other lines need to be connected to the A-axis, the rotation angle is limited, generally not exceeding ±300 degrees. Its limited working angle causes inconvenience in certain situations. Summary of the Invention

[0007] The positive and beneficial technical effects of this utility model are as follows: the rotation angle of this welding torch device can reach ±360 degrees, which expands the reach of the welding torch, and the application scenarios and work efficiency will be improved accordingly. The welding torch is connected to the output shaft through the fixed plate and the anti-collision device. If the welding torch is hit, the fixed plate will drive the anti-collision device to generate deformation and displacement. The anti-collision device can sense this in time and protect the welding torch. Attached Figure Description
