High-precision laser cutting machine for automobile sheet metal parts

Abstract

The invention discloses a high-precision laser cutting machine for automobile sheet metal parts, and particularly relates to the technical field of laser cutting machines, the high-precision laser cutting machine comprises a cutting machine table body and a protective frame, two guide sliding rails are arranged on the upper surface of the cutting machine table body, and guide moving frames are arranged on the inner walls of the guide sliding rails; the upper surfaces of the two guide moving frames are fixedly connected with the lower surface of the same moving support. According to the device, the lead screw, the threaded cap, the protective frame, the toothed bar, the gear, the grinding disc, the fan assembly, the middle box and the collecting filter box are arranged, meanwhile, the gear is meshed with the toothed bar while moving rightwards, meanwhile, the gear drives a connecting shaft and the grinding disc to rotate, and meanwhile dirt and unevenness adhering to the surface of an original part are ground through the grinding disc; and meanwhile, the fan assembly sucks and collects the cleaned sundries and waste through the middle box, the surface of the raw material can be cleaned, the influence of the subsequent laser cutting process is reduced, and the laser cutting precision and speed are obviously improved.

Description

technical field [0001] The invention relates to the technical field of laser cutting machines, and more particularly, the invention relates to a laser cutting machine for automobile sheet metal parts with high precision. Background technique [0002] The laser emitted by the laser cutting machine is focused into a laser beam with high power density through the optical path system, and the laser beam is irradiated on the surface of the workpiece to make the workpiece reach the melting point or boiling point, and realize the cutting operation of the workpiece, which is coaxial with the beam during laser cutting. The high pressure gas blows the molten or vaporized metal away. [0003] Laser cutting replaces traditional mechanical knives with invisible beams. It has the characteristics of high precision, fast cutting, not limited to cutting patterns, automatic typesetting to save materials, smooth incisions, and low processing costs. It will be gradually improved or replaced. T...

Problems solved by technology

[0006] The state of raw materials in the laser cutting process directly affects the quality of laser cutting. The state of the material surface affects its absorption of the beam, especially the surface roughness and surface oxide layer will cause obvious changes in the surface absorption rate. For raw materials with serious corrosion or oil pollution , which will not only affect the speed of laser cutting, but also cause holes to burst or cut continuously during the cutting process, and the high-pressure auxiliary gas may cause splashing when the melted waste is blown away. Therefore, a high-precision automotive sheet metal Metal parts use laser cutting machines to solve the above problems
