Abstract

The invention relates to the technical field of friction stir welding, in particular to a laser-assisted friction stir additive welding tool. A laser head and a push switch are arranged in a shell of the tool, and the push switch is electrically connected with the laser head; laser channels are formed in the side wall of a cutter handle at intervals, and the side wall of the cutter handle between every two adjacent laser channels is of a frame structure; in the rotating process, one part of a frame body structure is suitable for abutting against the pressing switch, so that the laser head is closed; and when the frame body structure is separated from the pressing switch, the laser head emits laser, so that auxiliary heating is carried out on the additive in the cutter handle through the laser channels. The tool adopts a full-mechanical structure, a laser can accurately heat a material and rapidly heat the material, high-speed friction stir additive manufacturing can be achieved, the defect of mistakenly heating the cutter handle caused by step loss of a motor system is avoided, the control logic of a control system is reduced, and system redundancy is reduced.

Description

technical field [0001] The invention relates to the technical field of friction stir welding, in particular to a laser-assisted friction stir additive welding tool and device. Background technique [0002] As a new solid phase additive technology, friction stir additive manufacturing has the advantages of low forming temperature and good properties of formed materials. However, in the process of adding materials, in order to satisfy the plasticization of the material by sufficient heat, extremely high speed and pressure are required. This will place great demands on the performance of the equipment. During friction stir additive manufacturing, the material needs a lot of temperature to plasticize. However, pure frictional heat generation will cause insufficient plasticization of the material, so auxiliary heat additive manufacturing is required. The laser acts as a good heat source to quickly heat the material to the desired temperature. However, the laser is a kind of c...
