Abstract

The invention discloses a laser spiral perforating device and device adopting the eddying effect for assisting in heating. The method includes the steps that (1) a first x-y movable platform is used for enabling the center of the workpiece perforating position to be located on a rotating shaft of a rotating platform device, and a second x-y movable platform is used for enabling the center of the workpiece perforating position to departure from a laser beam by one rotary-cut radius; (2) an eddy generation device is started to enable workpieces to form eddy current; and (3) the rotating platformdevice is started, a pumping of a laser device is started, a z-direction movement mechanism conducts downward feeding, and when the focal point is located on the workpiece surfaces, the z-direction movement mechanism conducts feeding at a low speed. In addition, the laser spiral perforating device adopting the eddying effect for assisting in heating comprises the laser device, a power case, a laser head, a CCD camera, a light guide pipe, the x-y movable platforms, the rotating platform device, the eddy generation device, the z-direction movement mechanism and a workpiece clamp. By means of the device and method, the small hole roundness is improved, and the small hole taper and recasting layer are reduced.

Description

technical field [0001] The invention relates to the drilling technology by using laser, in particular to a laser spiral drilling device and method using eddy current effect to assist heating. Background technique [0002] At present, laser drilling technology has been applied to many industries such as automobile industry, shipbuilding, aerospace, instrumentation and medical technology. Compared with traditional mechanical drilling methods, laser drilling technology has the advantages of high precision, fast speed, high efficiency, good economic benefits, no tool loss, and large depth-to-diameter ratio. It has become one of the main application fields of laser processing. However, for the drilling of high-precision instruments, it is necessary to drill high-quality group holes, such as air film cooling holes on the turbine blades of aero-engines, which have high requirements on the quality of the holes. The quality evaluation criteria of the holes are taper, roundness, and r...
