Description

Technical Field

[0001] The present invention belongs to the field of turning processing, and in particular relates to a laser-assisted turning processing device with adjustable light beam and a processing method. Background Art

[0002] Laser-assisted processing technology is a new processing method developed in recent years. It is widely used in the field of high-precision and high-quality manufacturing. Its purpose is to solve the problems of cracks, surface damage, severe tool wear and other problems caused by the hard and brittle characteristics of materials. Its core principle is to combine the laser beam with traditional cutting processing methods such as turning, milling, grinding and drilling. Through the high energy density and precise positioning of the laser, the yield strength of the material is reduced, the plasticity is enhanced, the plastic removal of difficult-to-process materials is achieved, and tool wear and workpiece surface and sub-surface damage are reduced. This technology can not only effectively improve the mechanical properties and surface roughness of difficult-to-process materials, but also has important application value, especially in the fields of micro-machining, complex surface processing and difficult-to-process materials such as high-temperature alloys and ceramics.

[0003] At present, laser-assisted processing technology and related equipment currently used still face some problems, as follows:

[0004] Problem 1: Laser beam control problem. The size of a traditional Gaussian laser beam is fixed, and the energy distribution is extremely high in the middle and extremely low at the edge. The uneven thermal effect leads to thermal deformation and thermal damage. In the prior art, in order to adjust the laser beam size, it is generally adjusted by adjusting the position of the laser emission port and the irradiation surface of the workpiece or by changing the laser type. The first adjustment method is difficult to implement and has poor flexibility in spot size control. The second method of changing the laser type is costly.

[0005] Problem 2: The problem of combining laser with turning system; Most of the ways of combining laser with turning system are that the laser beam output module is fixed above or on the side of the machine tool bed (for details, please refer to patent CN107234444A). The laser beam and the turning tool are at a certain angle, which limits the safe processing area and increases the risk of processing. Summary of the invention

DETAILED DESCRIPTION

[0035] The implementation scheme is further described below with reference to the accompanying drawings and examples.

If it is to be applied, the outer surface should be de-roughened. Turning is selected as the processing method. Due to the hard and brittle characteristics of the material itself, it is required that the laser not only always irradiates the workpiece in the area to be cut during the turning process, but also requires the laser energy to be irradiated uniformly to avoid thermal damage caused by the thermal effect of excessive energy concentration, in order to achieve uniform preheating and softening of the material in the area to be cut. At the same time, it is necessary to avoid the laser processing equipment occupying the area required for normal processing of the machine tool and the laser irradiating the tool. In order to solve the above problems, it is necessary to specially develop a new type of turning tool module with adjustable light beam and guided directional irradiation of the laser beam, as well as a beam fixing module that meets the assembly requirements of the turning tool module and the laser light output module.
