Laser cutting machine used for machining automobile interior trim part and machining method

Abstract

The invention discloses a laser cutting machine used for machining an automobile interior trim part. The cutting machine comprises a machine base, a supporting frame, an upper moving device, a cutting robot, a laser cutting enclosure device, a fixing device, a camera device and an electric control device; the supporting frame is mounted on the machine base, the upper moving device is supported above the machine base through the supporting frame, the upper moving device comprises a gear and rack transmission system driven by a stepping motor, the upper end of the cutting robot is connected with the lower end of the upper moving device, the fixing device is arranged on the machine base and close to the laser cutting enclosure device, the camera device is arranged on a cutting machine inlet and located on the upper portion of the supporting frame, and the electric control device is arranged outside the supporting frame; the laser cutting machine used for machining the automobile interior trim part can increase the cutting range, the laser cutting enclosure device and the cutting clamp fixing device are arranged, the influence on the surroundings is reduced, the fixing time of a cutting clamp is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a laser cutting machine and a processing method for processing automobile interior parts. Background technique [0002] At present, many automotive interior parts are cut by laser, which has the advantages of fast cutting speed, smooth cutting surface, high cutting precision, not affected by the shape of the workpiece, and can cut a variety of materials. The cutting method is to first fix the formed automotive workpiece On the laser cutting fixture, a robot is used to control the laser cutting machine to cut. Many cutting robots currently in use are fixed on the ground in the form of cantilever beams. Their fulcrums and nodes are prone to fatigue, and their operation stability is poor. The cutting range is limited. When encountering a long workpiece, the entire workpiece cannot be cut continuously at one time. There are no protective measures around many cutting devices. D...

The cutting range is limited. When encountering a long workpiece, the entire workpiece cannot be cut continuously at one time. There are no protective measures around many cutting devices. Due to the high brightness of the laser cutting, it has a greater impact on external interference. Many cutting fixtures lack mechanical fixing devices, and manual fixing is required, which requires a long fixing time
