Laser cutting machine

Abstract

The invention discloses a laser cutting machine. The laser cutting machine comprises a case, an observation window, a cover plate, a laser tool bit, a transverse guide rail, a longitudinal guide rail, a collecting hopper, a brake switch, a cooling fan, an operation panel, a laser tube, clamp rings, laser outlets, induced draft ports, driving electricity boxes, external connecting holes, a power plug, a laser generator, a reflecting mirror, a laser beam, a smoke sensor, a cooling gas pipeline, a first adjusting knob, a lens, a second adjusting knob, a nozzle, an optical sensor, a cooling water pipeline, an auxiliary gas pipeline, solenoid valves and auxiliary gas cylinders. The laser cutting machine has the beneficial effects as follows: the laser cutting machine has the function of stopping machining when the lens is burned out, and the optical sensor is mounted above the machining lens, can be used for measuring the light quantity at a machined part and also has functions of realizing focusing, preventing over-burning and the like; and the cooling gas pipeline is arranged, and nitrogen or dry air which can be sprayed to the lens from the upper side of the lens can have a cooling effect and is also applied to optical path clean-keeping.

Description

technical field [0001] The invention relates to a cutting device, in particular to a laser cutting machine, which belongs to the technical field of laser equipment application. Background technique [0002] The application of laser cutting machines in the industrial field continues to grow and has achieved great success, especially in the manufacturing industry, where most of the laser cutting machines in the industrial field are concentrated. Compared with other cutters, it has many advantages. For example, its high speed, high precision, high adaptability, etc., have solved many problems that cannot be solved by conventional methods in industrial production, and greatly reduced the labor intensity of workers. [0003] In the current laser cutting machine, there is no protection and purification device for the cutting head, the cutting head is easy to overheat, and the auxiliary gas lacks a control device when it is introduced, which is easy to cause waste, and the overall ...
