Noise reduction device of numerical control machine tool

Abstract

The invention relates to the technical field of numerical control, in particular to a noise reduction device of a numerical control machine tool. The noise reduction device comprises a box body, a first cavity is arranged in the box body, sound attenuation cotton is arranged on the circumferential inner wall of the box body, a first shaft rod is connected between the inner top and the inner bottom wall of the box body, a sliding block is arranged at the top end of each sliding rail, and a locking sleeve is arranged at the top end of each sliding block. Multiple sound attenuation vibration pieces are connected between the first shaft rod and a second shaft rod, a first connecting shaft is arranged at the connecting position of each sound attenuation vibration piece and the first shaft rod, a second connecting shaft is arranged at the connecting position of each sound attenuation vibration piece and the second shaft rod, the bottom end of each second shaft rod penetrates through the bottom end of the box body and extends towards the bottom end of the box body, and second shaft sleeves are connected to the connecting points of the bottom end of the first shaft rod and the box body. An electric appliance protection box is connected to the bottom end of the box body, and a first fixed plate is connected between the top end of the first connecting plate and the bottom end of the box body. Thus, the occupied space is small, mounting is convenient, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of numerical control, in particular to a noise reduction device for a numerical control machine tool. Background technique [0002] As we all know, a CNC machine tool is an automatic machine tool equipped with a program control system. The control system can logically process the program specified by the control code or other symbolic instructions, and decode it, express it in coded numbers, and pass it through the information carrier. Input the numerical control device, after calculation and processing, the numerical control device sends out various control signals to control the movement of the machine tool, and automatically process the parts according to the shape and size required by the drawing. [0003] CNC machine tools will generate a lot of noise during processing, which will affect the health of construction workers. Most of the existing noise reduction equipment is protected around the CNC machin...

[0003] CNC machine tools will generate a lot of noise during processing, which will affect the health of construction workers. Most of the existing noise reduction equipment is protected around the CNC machine tool, which takes up a large space and is not convenient for the installation of noise reduction devices. It is practical and the existing CNC machine tools can only simply use sound-absorbing materials to absorb noise, and the sound-absorbing effect is poor; in addition, the noise frequency or sound pressure produced by different processing processes of CNC machine tools is different, and the existing noise reduction effect cannot Match different noises, the noise reduction effect is poor
