AI Technical Summary

Technical Problem

Traditional laser cutting machines have low levels of automation in their protective devices, making it difficult to match the operating speed of the equipment. This poses safety hazards and is inconvenient to clean, affecting the efficiency of continuous high-precision processing.

Method used

The protective cover, driven by rack, pinion, and cylinder, opens and closes automatically. Combined with bevel gear set and transmission screw, it realizes the automated movement of the cleaning components, ensuring that the protective action is synchronized with the processing flow. Automatic cleaning is achieved by the scraper making adaptive contact with the workpiece surface.

Benefits of technology

It achieves a precise match between the protective cover and the cutting process, improving safety, and enhances debris removal efficiency through automated cleaning, avoiding the time and potential misoperation caused by manual intervention.

Abstract

The utility model discloses a laser cutting machine with a protective structure, which relates to the technical field of laser cutting machines and comprises a machine tool, a laser cutting component is mounted in the machine tool, and a protective component is arranged on the machine tool. The laser cutting assembly comprises a longitudinal sliding block driven by a second driving part to move, and a laser cutter is fixedly connected to one side of the longitudinal sliding block. The protection assembly comprises a protection cover sliding on one side of the machine tool, one side of the protection cover is fixedly connected with a sliding plate, and one side of the sliding plate is fixedly connected with a rack. Through the rack and the circular gear, automatic synchronization of opening and closing of the protective cover and the cutting process is achieved. Before cutting, an air cylinder drives a rack to be meshed with a gear to drive a sliding plate and a protective cover to be completely closed, a totally-closed machining space is formed, and chippings are thoroughly prevented from splashing; after cutting is completed, the cover is reversely driven to be opened, the protection action is accurately matched with the machining time sequence, and safety is remarkably improved.
