SUPPORT of machine tools with an active vibration isolation

摘要

The invention relates to mechanical engineering and can be used for vibration control of precision machine tools, such as grinding.; The object of the proposed device is to increase the dynamic characteristics of the machine and secure it against external vibrozashchity forced vibration in a wide frequency range.; Technical result is achieved due to the fact that a machine tool with an active vibration isolation support mounting comprises a cylindrical body with a hydraulic chamber filled with magnetorheological liquid, with the piston rod, valves, sealing assemblies and the guide, the winding of the electromagnet, the control device and sensors. Said lower cylindrical housing part arranged coaxially in the base of the support with a rubber element and the outside of the upper projecting part comprises an electromagnet winding, and between the upper end of the cylindrical body and the support surface of the machine frame on the rod, fixed in the bore of the machine frame, the Belleville springs are arranged. The winding of the electromagnet associated with vibration detectors, installed on the machine base via a control device in the form of transducers, the controller and amplifier.; This arrangement improves the dynamic properties of the machine and its reliability vibration protection from external forced vibration in a wide frequency range.; Technical effect - increasing by reducing processing errors of the quality of parts of the mold by reducing vibration effects by active vibration isolation magnetorheological fluid viscosity change depending on signals from the vibration sensors. 1, Fig.
