Problems solved by technology

[0002] At present, the vibration reduction methods used on vertical machining centers mainly include damper vibration reduction, bean bag vibration reduction, and pad iron vibration reduction. However, no matter which of the above vibration reduction methods, there are the following problems, that is, the control frequency band Narrow and non-adjustable; in addition, for the vertical machining center with a wide operating frequency band, the vibration reduction effect achieved by the above vibration reduction method is not ideal; and for the vibration reduction method used in the machining center for cutting vibration, there are many It is a software compensation method, which is limited by the cutting conditions and the feedback speed of the control system during use

Abstract

The invention provides a power vibration absorber comprising a support frame (1), a servo motor (2), a screw rod (7), a transmission nut (8), a vibration reducing rod (10), a vibration reducing seat (9) and a mass block (11), wherein the servo motor (2) is fixed at one end of the support frame (1); the screw rod (7) is driven by the servo motor (2); the transmission nut (8) is in thread engagement with the screw rod (7); the vibration reducing rod (10) is fixedly connected with the transmission nut (8); the vibration reducing seat (9) is fixedly connected with the support frame (1) and penetrated by the vibration reducing rod (10); and the mass block (11) is fixed on the vibration reducing rod (10) and arranged opposite to the support frame (1). The natural frequency of the power vibration absorber can be regulated through a motor, therefore needed vibration reducing bandwidth can be achieved through less vibration absorption mass; and in addition, the invention has simple structure and higher system reliability.
