Power-off protection device for numerical control machine

Abstract

A power-off protection device for a numerically controlled machine tool, comprising a battery box at the top and an electrical box at the bottom, the inside of the battery box is divided into several layers by several partitions, and each layer is provided with several battery modules, The inside of the electrical box is equipped with a transformer, a circuit board, a power output socket and a power input plug. The power inlet of the transformer is connected in series with several battery modules, and the power outlet is connected in parallel with the power output socket and the power input plug. The invention overcomes the deficiencies of the prior art. The power-off protection device includes a battery box and an electrical box. The electrical box is provided with a power output socket and a power input plug. The power input plug is connected to an external power source to receive power and charge the battery. The output socket and the CNC machine tool deliver power to it. When the CNC machine tool suddenly loses power, the machine tool is seamlessly connected to the battery through the electrical box, so that the machine tool has a power-off buffer stage and can be shut down normally, thus playing a role in the maintenance of the CNC machine tool. protection of.

Description

technical field [0001] The invention relates to the technical field of power-off protection devices, in particular to a power-off protection device for numerically controlled machine tools. Background technique [0002] CNC machine tool is the abbreviation of numerical control machine tool, which is an automatic machine tool equipped with a program control system. The control system can logically process programs with control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the numerical control device through the information carrier. After calculation and processing, various control signals are sent by the numerical control device to control the movement of the machine tool, and the parts are automatically processed according to the shape and size required by the drawing. CNC machine tools solve complex, precise, small-batch, and multi-variety parts processing problems. It is a flexible, high-efficiency automatic machine...

Problems solved by technology

[0004] When the CNC machine tool is working, it is controlled by its matching computer. When the machine tool suddenly loses power, it is easy to cause the data being processed to be lost, which affects the service life of the computer equipment and is easy to cause damage to the hard disk. The voltage fluctuation of the computer hardware will impact the chips, circuits, resistors, etc. of the computer hardware; and the tool and the workpiece will remain in contact when the power is suddenly cut off. At this time, the tool is still rotating due to inertia, but the rotation force is insufficient, and it is easy to jam the tool
