Multi-interface monitoring laser cladding and impact strengthening combined machining device

Abstract

The invention discloses a multi-interface monitoring laser cladding and impact strengthening combined machining device. The multi-interface monitoring laser cladding and impact strengthening combinedmachining device comprises a mechanical arm and a follow-up bracket platform which are connected with each other through a flange at the tail end of the mechanical arm, wherein a laser cladding head,a left limiting switch, a right limiting switch, a turntable bearing assembly, a servo motor unit and a paraxial multi-interface monitoring platform are mounted on the follow-up bracket platform; theturntable bearing assembly is further connected with a laser impact strengthening head unit, the laser impact strengthening head unit is located in a limiting region between the left limiting switch and the right limiting switch, and the limiting region is 0-180 degrees; one side wall of the laser cladding head is connected with a coaxial multi-interface monitoring platform through a first connecting piece; and the servo motor unit is matched with the turntable bearing assembly for use. The device can prolong the fatigue life of mechanical parts.

Description

technical field [0001] The invention belongs to the technical field of laser additive manufacturing, and relates to a multi-interface monitoring laser cladding and impact strengthening composite processing device. Background technique [0002] In recent years, laser additive manufacturing has made great progress, but thermal stress control problems and internal quality control issues still restrict the use of laser additive manufacturing parts on key structural parts. Although the subsequent heat treatment and hot isostatic pressing treatment of the formed parts can eliminate the residual thermal stress and close the small metallurgical defects, it still cannot solve the warping deformation and large metallurgical defects during the forming process, and its high cycle fatigue performance has not been improved. Reach the forging level. At present, in order to improve the fatigue life of mechanical parts, the traditional process is that after the mechanical parts are machined...
