The shock absorber in the prior art often consists of simple springs, block-shaped Composed of rubber, etc., this technical solution can achieve a certain shock absorption effect in the case of a single transverse shock and longitudinal shock, but the vibration of the machine tool is often combined vibration, so the shock absorption effect is poor, not only the life of the shock absorber itself is short And it is easy to shorten the life of the machine tool. The machine tool shock absorber is placed under the machine to support the weight of the machine. It has the functions of shock absorption and support, and is commonly used in CNC machine tools. Generally, shock-absorbing rubber is used as a floor mat. The shock-absorbing rubber can effectively attenuate the vibration of the machine itself, reduce the external transmission of vibration force, prevent the introduction of vibration force, ensure the accuracy and quality of processing dimensions, and control the resonance transmission of vibration force and noise in building structures.
