An automatic power-off structure and electrical automation laser cutting machine

Abstract

The invention discloses an automatic power-off structure and an electric automatic laser cutting machine. An elastic structure is arranged on one side of the worktable, and a switch assembly is arranged under the elastic structure; When laminating, roll and fit with the roller; the movable platform is close to the elastic structure along the horizontal direction, and when the front side of the movable platform is in contact with the roller in the elastic structure, it drives the roller and the swing arm to rotate around it and the workbench Swing at the center, at this time, the elastic telescopic rod group is stretched and has elastic potential energy; after the swing arm swings to the end of its stroke, the movable platform continues to push the rotating roller and the swing arm to swing, when the swing arm crosses the end of its stroke, through The elastic potential energy of the elastic telescopic rod group drives the swing arm down rapidly and drives the crank slider assembly to move, drives the moving contact to separate from the static contact, and powers off the equipment; it has the function of automatically powering off the equipment when the movable platform reaches the end of its stroke .

Description

[0001] The invention relates to electrical automation equipment, in particular to an automatic power-off structure and an electrical automation laser cutting machine. Background technique [0002] Laser cutting is widely used in industry, and has the advantages of narrow slit, small deformation of workpiece, non-contact processing, high adaptability and flexibility. [0003] Most organic and inorganic materials can be cut with lasers. In the metal processing industry where the industrial manufacturing system occupies a large part, many metal materials, no matter what kind of hardness it is, can be cut without deformation. For many electromechanical manufacturing industries, because the modern laser cutting system controlled by computer programs can easily cut workpieces of different shapes and sizes, it is often preferred over punching and molding processes; although its processing speed is still slower than die punching, But it has no mold consumption, no need to repair the ...

AI Technical Summary

Problems solved by technology

[0004] Most laser cutting machines in the prior art control laser cutting through microcomputer programs. Microcomputer control requires complex sensors and various electronic units, so there are large errors in the use process, and the failure rate is high and maintenance is expensive.
