The invention discloses a laser welding machine reflector path optical mirror maintaining device and a maintaining method thereof. The device comprises a laser resonant cavity output unit, a reflector path mirror frame and a laser processing head which are sequentially connected through a reflector path pipeline; a first mirror is arranged in the reflector path mirror frame, a second optical reflection unit is arranged in the laser processing head, a laser generation device, a laser strength detection device and a cleaning mechanism are further included, the laser generation device is arranged in the laser resonant cavity output unit, the laser strength detection device is arranged on the outer side of the laser processing head, and the cleaning mechanism comprises a spraying shower nozzle, a pressure spraying unit, an injection shower nozzle and a gas pipeline. The problems that when a laser welding machine reflector path optical mirror is maintained, the optical mirror must be detached down to be cleaned, after reinstallation, adjusting difficulty is large, an optical device is prone to damage, and the welding line quality is affected are solved.
Description
technical field [0001] The invention relates to a maintenance device of a laser welding machine, and more specifically relates to a maintenance device and a maintenance method for an optical reflection mirror of the outer optical path of a laser welding machine. Background technique [0002] Cold-rolled C202 acid-rolled laser welding machine is mainly used for welding hot-rolled strip steel with a thickness of 2mm-3mm and a hardness of HR30Te between 42-65. The output mirror of the laser source body of the welding machine has a spot diameter of 22mm and a laser beam with a power of 8KW. The welding of the steel plate by the laser is realized through multiple reflections and final focusing of the external optical path; the external optical path system of the existing welding machine laser beam adopts the basic airtight technology of the stainless steel pipeline. The processing head is composed of a compressed air curtain at the light outlet of the laser processing head, so th...
