Description

Automatic welding device for spare and accessory parts of heading machine for mining machinery Technical Field The invention belongs to the technical field of welding, and particularly relates to an automatic welding device for parts of a heading machine for mining machinery. Background The heading machine is used as a mining machine and is core equipment in coal mining and tunnel construction. Because the working environment is extremely severe and needs to bear huge impact, vibration and torque, the main parts, such as a machine body, a cutter head, a supporting beam and the like, are made of high-strength steel. When machining these parts, it is often necessary to perform a welding operation. The patent with the bulletin number of CN215034905U discloses a heading machine spare and accessory part welding set with locate function, which comprises a base, be provided with the fluting in the middle of the base, both sides are provided with the spout in the middle of the fluting, spout top sliding connection has the spliced pole, be provided with the slider in the middle of the spliced pole, one of them the slider top is provided with fixed disk one, fixed disk one top is provided with the carousel, another the slider top is provided with fixed disk two, fixed disk two tops are provided with the locating plate.

However, the above technical solution has the following disadvantages in the practical application process: When welding spare parts of the heading machine, two rectangular pipes with one ends being forty-five-degree inclined planes are often required to be butted into a right-angle structure and welded into a whole to be used as a supporting beam or a frame structure of the heading machine. In order to ensure the butt joint precision, manual operation is conventionally relied on by workers, however, when the number of workpieces to be welded is huge, the method is high in labor intensity, and is extremely easy to generate butt joint deviation due to fatigue or errors, so that the continuous welding efficiency is seriously affected. If the manipulator is adopted to replace manual work, the labor intensity problem can be relieved, but when the messy piled workpieces are processed, the manipulator needs to rely on a visual detection technology to identify and position each rectangular pipe, but because the workpieces are mutually covered, the visual system is difficult to accurately extract the azimuth characteristics of the rectangular pipes, so that the identification difficulty is high, the clamping error is frequent, and the continuous operation of welding work can be blocked.
