Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, and in particular to a laser metal cutting machine that is easy to maintain. Background Technology

[0002] A laser cutting machine is a machine that uses a laser emitted from a laser source to focus a high-power, high-density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece to reach its melting or boiling point. At the same time, high-pressure gas blows away the molten or vaporized metal, thereby achieving the effect of laser cutting. Chinese patent application number 202322120612.1 discloses a laser cutting machine that facilitates heat dissipation for metal sheets.

[0003] However, the above technical solutions lack protective structures, which poses certain risks during the manufacturing process. If the cover is installed directly, its presence will affect the convenience of equipment maintenance and hinder heat dissipation. Utility Model Content

The top of the protective cover is bolted to the bottom of the lifting frame. The top of the baffle is hinged to the material inlet on the side of the protective cover. The shaft of the cover plate is hinged to the opening at the top of the protective cover. There are two cooling fans and two filter bags. The surfaces of the two cooling fans are respectively engaged with the two heat dissipation vents of the protective cover. The air outlet of the cooling fan is engaged with the inlet of the filter bag.

[0010] There are two lifting ropes, which are bolted to the top of the lifting frame.

[0011] The lifting mechanism, connected to the lifting rope, can cover the main body of the laser metal cutting machine for protection through a protective cover. At the same time, a cooling fan can dissipate heat to prevent heat buildup. Through the lifting rope and other structures, the protective cover can be moved upwards, making it convenient for users to maintain the main body of the laser metal cutting machine.

[0012] In a preferred embodiment of this utility model, the lifting mechanism includes a power motor, a worm gear, a worm wheel, and a lifting assembly. The output end of the power motor is keyed to the right end of the worm gear. The surface of the worm gear meshes with the top of the worm wheel. The worm wheel is keyed to the lifting assembly.

The structure of the worm gear and worm wheel can have a self-locking structure to prevent the worm wheel from driving the worm gear to rotate. The worm wheel can drive the lifting assembly to rotate.

[0013] As a preferred embodiment of this utility model, the lifting assembly includes a rotating shaft and a winding wheel. The worm gear's axis is keyed to one end of the rotating shaft. There are two winding wheels, and the axes of both winding wheels are keyed to the surface of the rotating shaft. The inside of the winding wheel is wound around the top of the lifting rope. The worm gear can drive the rotating shaft to rotate, and the rotating shaft can drive the two winding wheels to rotate. The winding wheels can wind up the lifting rope and move it upward.

[0014] In a preferred embodiment of this utility model, the surface of the power motor is connected to the recessed bolt on the top of the support frame, and both ends of the rotating shaft are rotatably sleeved with the holes on the top of the support frame. The power motor is fixed by the support frame, which facilitates the power motor to drive the worm gear to rotate. The rotating shaft is rotatably set with the support frame through bearings to ensure the stability of the rotating shaft rotation.

[0015] As a preferred embodiment of this utility model, the edge of the protective cover is bonded with a sealing strip, and the two ends of the bottom of the two lifting frames are respectively bolted to the top of the two protective covers. The sealing strip of the protective cover can seal and protect the safety of processing.

[0016] As a preferred embodiment of this utility model, the screw holes on the surface of the lifting frame are connected to a tension bolt, which corresponds to the support frame and can fix the lifting frame to the surface of the support frame.
