Problems solved by technology

However, laser-assisted processing is rarely used when facing inner hole processing
The whole process of laser-assisted processing needs to adjust the spatial position of the laser. Due to the space limitation of the inner hole processing, the activity space of the laser is limited, so that the laser cannot be accurately irradiated to the surface of the workpiece.
The development of laser-assisted processing has been hindered in the case of inner hole cutting. The existing laser-assisted processing technology cannot solve the problem of inner hole processing, which makes some difficult-to-machine materials increase the wear of the tool and cannot improve the inner hole. Machining efficiency and not up to the standard machined surface quality

Embodiment 2

[0050] On the basis of the laser-assisted inner hole machining tool provided in Embodiment 1, this embodiment provides a method for adjusting the incident angle of the laser, including the following steps:

[0051] Step 1. Introduce the laser: the laser fiber 31 passes through the first inner hole 33 and the second inner hole 34 of the first block 30, and the laser passes through the convex lens 32 and then enters the interior of the cutter bar 2, and then enters the second through the first through hole 23. On the glass of the first concave lens 42 in the module 4;

[0052] Step 2, adjust the reflection angle: manually adjust the knob on the first adjustment rod 44 at the bottom of the block bottom plate 41 of the second block 40, so that the mirror of the first concave lens 42 in the second module 4 rotates around the fixed pin 46 , to adjust the reflection angle of the laser.

[0053] Step 3. Adjusting the incident angle: by manually adjusting the knob on the second adjust...

Description

technical field [0001] The invention relates to the technical field of laser-assisted processing, in particular to a tool for laser-assisted processing of an inner hole and a method for adjusting a laser incident angle. Background technique [0002] Laser heating assisted milling technology is to irradiate a high-energy laser beam on the material removal area, increase the local temperature of the workpiece material in a short time, change the cutting performance of the material, and then use the tool for processing. By heating the material, the plasticity of the material is improved, the yield strength is reduced to below the fracture strength, the cutting force is reduced, the tool wear is reduced, and the cutting chatter is reduced, thereby achieving the purpose of improving processing efficiency, reducing cost, and improving the quality of the processed surface. [0003] Laser-assisted processing is suitable for a variety of processing conditions, and it has strong adapt...
