Laser processing equipment for thin-wall pipes

Abstract

The invention provides laser processing equipment for thin-wall pipes, which comprises a rotary shaft, a linear shaft, a laser cutting head, an auxiliary high-pressure air-supplying unit, a Z axis module, a laser generator, a collimation and beam expanding lens, a lighting source, a 45-degree reflector, a CCD (Charge Coupled Device) and a control system. The laser cutting head comprises a laser nozzle, a protection lens and a focusing lens. The rotary shaft comprises a motor, a coupler, a worm, a worm gear, a pull-rod module, a shell, an end cover and a clamp head. The pull-rod module comprises a pull-rod cover, a piston, a pull-rod seat, a rolling bearing, a shaft sleeve and a hollow pull rod. The CCD is used for observing the focusing condition of optical spots during position adjusting of the laser optical spots, checking the processing condition anytime during the machining process, and videoing the whole machining process. The control system comprises a moving control unit fro controlling the linear shaft, the rotary shaft and the Z axis module, and a laser control unit for controlling the laser generator. The laser processing equipment for the thin-wall pipes disclosed by the invention is quick in processing speed and high in processing accuracy.

Description

[0001] technical field [0002] The invention belongs to the field of laser micromachining of thin-walled pipes, and relates to laser processing equipment, in particular to laser processing equipment for thin-walled pipes. [0003] Background technique [0004] Vascular stent refers to the placement of internal stents in the diseased segment on the basis of luminal balloon expansion to support the stenotic and occluded segment of the vessel, reduce the elastic retraction and reshaping of the vessel, and maintain the smooth blood flow in the lumen. The role of the scaffold is to keep the blood vessels open. Some internal stents can also prevent restenosis. Mainly divided into coronary stents, cerebrovascular stents, renal artery stents, aortic stents, etc. [0005] The processing of vascular stents in my country develops late, the technology is relatively backward, and there is a big gap in processing accuracy and quality compared with foreign countries. At present, most o...
