[0002] With the continuous development of science and technology, the demand for high-performance materials in various industries is increasing. Due to the physical and chemical characteristics of these high-performance materials, traditional processing methods often have low processing efficiency, low processing accuracy, and difficult to guarantee processing quality. , and processing defects such as molten layers and oxides will appear when laser processing is used, so an auxiliary device is urgently needed to solve various problems that occur in the current processing of high-performance materials

[0003] In recent years, some scholars and researchers have done a lot of research on laser processing. For example, the patent (201721633214.8) proposed an ultrasonic vibration-assisted laser processing device, which generates vibration through an ultrasonic generator, and then transmits the vibration to the laser through the medium water. Although the workpiece to be processed can reduce processing defects to a certain extent, since the vibration is transmitted through the medium, the amplitude and frequency of the vibration cannot be accurately controlled, so the stability of the processing quality cannot be guaranteed.

[0004] In order to solve the problems of recasting layer, oxide, melt splash, taper, low processing efficiency and low processing quality during processing, it is necessary to design a semi-automatic auxiliary laser processing device that can assist the laser to drill holes and realize Three-degree-of-freedom ultrasonic vibration is assisted to solve processing defects such as recasting layer, oxide layer, and microcracks, as well as problems such as low processing efficiency and low processing quality; the use of auxiliary air blowing can solve the problem of molten material splashing during processing
