Electric cabinet

Abstract

The invention discloses an electric cabinet which comprises a cabinet body and components arranged in the cabinet body, and the electric cabinet is characterized in that the components consist of a high-pressure component and a low-pressure component; the cabinet body is separated from the middle, including a first cabinet body and a second cabinet body; the high-pressure component is arranged in the first cabinet body, the low-pressure component is arranged in the second cabinet body, the first cabinet body and the second cabinet body of the electric cabinet are respectively and internally provided with a fan for radiating; the electric cabinet is further provided with a cabinet door, the outer side of the cabinet door is provided with a door lock and a plurality of control buttons, and the control buttons are orderly arranged on the cabinet door; a display panel for displaying control parameters of an engraving and milling machine is arranged on the cabinet door; and two protective handles are arranged on the cabinet door and arranged on two sides of the control buttons. The electric cabinet avoids electromagnetic interference between the high-pressure component and the low-pressure component, is safe and reliable as the electric components are radiated by the fan, has a reasonable structure, and is safe to use and good in reliability.

Description

technical field [0001] The invention relates to an electric control box, in particular to an electric control box for an engraving and milling machine. Background technique [0002] The existing CNC engraving and milling machine will install an electric control box outside the processing room to control the various operations of the engraving and milling machine. The electric control box mainly includes two parts: the control part and the operation display part. Among them, the electric control box is generally equipped with air switches, relays, contactors, circuit breakers, fuses (fuse), integrated circuits, sockets and other electrical components. , these control components and connection circuits are designed according to the control requirements of specific equipment. The electric control box of the existing engraving and milling machine is generally integrated, and all components are in one box. Some of these components are high-voltage components, and some It is a lo...

Problems solved by technology

The electric control box mainly includes two parts: the control part and the operation display part. Among them, the electric control box is generally equipped with air switches, relays, contactors, circuit breakers, fuses (fuse), integrated circuits, sockets and other electrical components. , these control components and connection circuits are designed according to the control requirements of specific equipment. The electric control box of the existing engraving and milling machine is generally integrated, and all components are in one box. Some of these components are high-voltage components, and some It is a low-voltage component, which is placed in the same box. Electromagnetic interference will occur between the high-voltage component and the low-voltage component, which will affect the normal use of the equipment, and even cause damage and failure of some components, making the machine unsafe during operation. reliable
