AUXILIARY MECHANISM FOR LASER BEAM MACHINE PERFORMING CORRECTION OF OPTICAL AXIS, CUTOFF OF LASER BEAM, AND DISPLAY OF MACHINING POINT AND LASER ABSORBER USED FOR CUTOFF OF LASER BEAM

摘要

PURPOSE: To contrive improvement in operability and reduction in cost by designing an auxiliary mechanism of a laser beam machine so that optical axis correction can be carried out in addition to laser beam intercept and machining point display. CONSTITUTION: An auxiliary mechanism for a laser beam machine, which is provided between a laser generator 5 and a light guiding tube 7, is constituted of an auxiliary light beam 1 for optical axis correction and machining point display, a first movable reflection mirror 2 for exchanging positions between an optical axis correction position and a machining point W display position, a second movable reflection mirror 3 for making a visible ray VR enter the laser generator 5, a third movable reflection mirror 4 for displaying the machining point W, and a dome absorber 6 for a reflected laser beam LB; thereby performing optical axis correction, machining point display and laser beam intercept. As a result, an operation for optical axis correction can be facilitated, enabling the manufacturing cost of the equipment to be reduced and safety to be improved.
