Laser in-situ auxiliary turning tool and using method thereof

Abstract

The invention relates to the technical field of precision machining, in particular to a laser in-situ auxiliary turning tool and a using method thereof. The laser in-situ auxiliary turning tool comprises a tool handle and a blade mounted on a mounting surface arranged at the front end of the tool handle, a through hole allowing a laser beam to pass through is formed in the tool handle, the surface, making contact with the mounting surface, of the blade inclines to serve as a laser incident surface, an included angle is formed between the laser incident surface and the through hole, a laser isarranged at the end, away from the laser incident surface, of the through hole, and laser beams emitted by the laser are refracted by the laser incident surface through the through hole and then transmitted to a workpiece corresponding to the tool nose part of the blade in situ to preheat the workpiece. The laser in-situ auxiliary turning tool has the beneficial effects that in-situ auxiliary heating of the workpiece is achieved, and the incident angle of the laser beams can be flexibly adjusted by adjusting the relative positions of the laser and the through hole.

Description

technical field [0001] The invention relates to the technical field of precision machining, in particular to a laser in-situ assisted turning tool and a using method thereof. Background technique [0002] When processing difficult-to-machine hard and brittle materials such as silicon, germanium, and ceramics, due to the high hardness of the material, brittle fracture of the workpiece often occurs during the processing. Using the laser-assisted method, using the laser to heat and soften the workpiece material, the processing can be transformed from brittle processing to plastic cutting, and better processing results can be obtained. [0003] The existing laser-assisted processing device of Company A is used for laser out-of-position auxiliary processing. During the processing, the laser heating and softening of the material and the tool cutting are not in place, that is, the laser heating workpiece and the tool cutting workpiece are not in the same position at the same time. ...

AI Technical Summary

Problems solved by technology

However, due to the optical-mechanical structure integration inside the tool handle, the adjustment of the laser incident angle is inflexible and inconvenient when the laser is incident in situ; and the hollow tool handle will lead to insufficient rigidity of the tool, which is prone to instability

[0005] Summary: The existing technology has the following problems for laser-assisted processing. First, in-situ auxiliary heating cannot be realized, and the utilization rate of laser energy is low; second, the adjustment of laser incident angle is not flexible.
