Deep-hole numerical control fine cold-welding equipment

Abstract

The invention provides deep-hole numerical control fine cold-welding equipment which comprises a welding machine track, a welding machine, a long rod welding torch, a self-correcting fixed-distance rod and a lifting type torch frame, wherein the welding machine travels on the welding machine track; the welding machine is connected to one end of the long rod welding torch; the lifting type torch frame is used for supporting the long rod welding torch; the self-correcting fixed-distance rod is arranged at the lower end of the other end of the long rod welding torch; the lower end of the fixed-distance rod is provided with a smooth round head or a mounting traveling ball; a torch head at the other end of the long rod welding torch is arranged vertically; a nozzle faces downwards; and a wire outlet end of a wire feeding guide pipe is horizontally opposite the outlet side of the nozzle. The deep-hole numerical control fine cold-welding equipment solves the problem that an outer wall and aninner hole are not concentric through the self-correcting fixed-distance rod, and solves the problem of arc voltage stability through the lifting type torch frame. In addition, the angle setting of the wire feeding guide pipe ensures the stability of welding forming.

Description

Technical field [0001] The invention relates to a welding equipment, in particular to a deep-hole numerical control fine cold welding equipment. Background technique [0002] In the field of remanufacturing, the additive welding technology of the inner and outer walls of various pipes is the key technology, and the welding quality directly determines the remanufacturing quality of the product. [0003] In the deep hole welding process, the main problem is that the outer wall and inner hole of the pipe are not concentric. After the pipe is fixed by the outer wall, the distance between the welded joint and the inner hole wall caused by the misalignment problem is inaccurate, the height fluctuates, and the welding quality difference. [0004] The current commonly used method is to install a distance sensor on the welding head to adjust the position of the welding head in real time to achieve refined welding. However, this process is limited to pipes with shallow hole depths. The weldin...
