[0002] CNC machine tools are digitally controlled machine tools, which are automated machine tools equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, and express them in coded numbers. They are input into the CNC device through information carriers, and various control signals are sent by the CNC device after calculation and processing to control the movement of the machine tool, and automatically process parts according to the shape and size required by the drawing. The base of the CNC machine tool is the bottom structure that supports the main body of the CNC machine tool, and it bears the weight of the entire machine tool.

A CNC machine tool base in this patent adopts multi-stage vibration reduction, wherein the support contacts the gasket as the first-stage vibration reduction device, and the shock-absorbing base is provided with an isolation groove corresponding to the gasket, thereby the support transmits the vibration to the shock-absorbing base, and the isolation groove limits the vibration position of the shock-absorbing base to the contact position, preventing vibration from occurring on other surfaces of the shock-absorbing base, reducing vibration and noise, and the isolation groove is opposite to the electromagnetic shock-absorbing bracket, and the electromagnetic shock-absorbing bracket can dynamically adjust the shock-absorbing damping according to the vibration size, with good stability and good shock-absorbing effect.

Most of the clamping component bases are fixed on the upper surface of the machine tool base and fixedly connected to it, which is inconvenient to use when height adjustment is required. Therefore, a CNC machine tool base is proposed to address the above shortcomings. Utility Model Content
