Problems solved by technology

But the disadvantage is that only one material can be repaired
If only changing the welding torch and re-welding will make the temperature of the shaft out of the range of the welding process, it will require special mechanical equipment for multiple welding materials

Abstract

An automatic shaft multi-layer repair welding device comprises a platform (4). A shaft rotary fixing device is arranged on the platform (4) in parallel. The automatic shaft multi-layer repair welding device further comprises a welding operation rack (8). Three lead screws (9) are arranged on the welding operation rack (8) and are in central symmetry about the rotary axis of the shaft rotary fixing device. Driving nuts (10) are matched with the lead screws (9) and connected with a welding gun (11). A radial adjusting mechanism (12) and an angle adjusting mechanism (13) are arranged on the welding gun (11). The radial adjusting mechanism (12) can adjust the distance between a welding wire of the welding gun and the shaft repair welding surface in the radial direction of the axis of a welded shaft. The angle adjusting mechanism (13) can appropriately adjust the welding wire of the welding gun (11) to be flush with the rotating axis in the circumferential direction. The automatic shaft multi-layer repair welding device is simple in structure and practical and can conduct multi-layer repair welding on the shaft at the same time.

Description

technical field [0001] The invention relates to the technical field of shaft welding tooling, in particular to an automatic multi-layer repair welding equipment for shafts. Background technique [0002] On the steel pipe production line, the rollers are the most stressed and worn. After a long time of use, the wear between the roller and the roller shaft is also quite serious. According to the production needs of the workshop, in order to ensure the quality of the product, the accuracy of the equipment must be guaranteed. When the wear between the shaft and the roller is serious, the gap increases, and the operation of the roller is unstable, resulting in the product quality cannot be guaranteed. The traditional way is to make a new shaft, and the more economical way is to manually repair the damaged shaft. One worker can only repair 3 shafts per day. The method of manual repair welding is to lay the shaft flat Repair welding is done directly on the steel plate. After one ...
