Abstract

The invention relates to a transmission shaft torsional vibration crack welding system and method fused with laser machining and 3D printing. The transmission shaft torsional vibration crack welding system comprises a laser machining module capable of conducting laser scanning and laser welding function switching, and a 3D printing module with a 3D printing filling solder function. According to the system, wide-depth cracks generated by torsional vibration of a transmission shaft are welded through a filling mode, and filling can realize precise machining through laser scanning and 3D printing; secondly, characteristics of laser machining are utilized, the machining belongs to non-contact point machining, the machining time is short, the cooling speed is high, the heat influence area is small, the secondary machining problem after wide-depth seam welding is eliminated, the mechanical strength of the transmission shaft after welding machining can be effectively guaranteed, and the secondary utilization of the torsional vibration damaged shaft can be realized; and finally, the system can achieve combined control of the two modules and the three functions, starting and stopping of thethree functions are completed through mode switching and control instructions, the system is simplified, and the control efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of laser processing and rapid prototyping, in particular to a transmission shaft torsional vibration crack welding system and method that integrates laser processing and 3D printing. Background technique [0002] In laser processing technology, laser welding technology developed earlier and is relatively mature, and in the welding process, the laser welding method has a small focus point and a relatively small heat-affected zone. At the same time, the laser processing speed is fast and the cooling speed is also fast. Therefore, the laser The internal stress and deformation of the drive shaft caused by welding are almost negligible. Compared with traditional welding methods, laser welding has more advantages in crack welding of drive shafts that require higher mechanical structural performance. However, limited by the principle of laser welding, laser welding does not require fillers, so laser welding is main...
