Automatic power-off structure and electric automatic laser cutting machine

Abstract

The invention discloses an automatic power-off structure and an electric automatic laser cutting machine. The automatic power-off structure is characterized in that an elastic structure is arranged, in a swinging mode, on one side of a workbench, and a switch assembly is arranged below the elastic structure; a movable platform is attached, in a rolling mode, to a rotating roller when getting closeto the elastic structure to be attached to the elastic structure; the movable platform gets close, in the horizontal direction, to the elastic structure, when the front side of the movable platform makes contact with the rotating roller in the elastic structure, the rotating roller and a swing arm are driven to swing around the rotating center of the swing arm and the workbench, and at the moment, an elastic telescopic rod set is stretched and has elastic potential energy; and after the swing arm swings to a travel terminal, the movable platform continues to push the rotating roller and the swing arm to swing, and at the moment when the swing arm crosses the travel terminal, the swing arm is driven by elastic potential energy of the elastic telescopic rod set to rapidly swing downwards and drive a crank sliding block assembly to act, a movable contact is driven to be separated from a static contact, and equipment is powered off. The automatic power-off structure has the function of automatically powering off the equipment when the movable platform reaches the travel terminal.

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 ...

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.
