Device and method for automatically suppressing milling vibration of thin-walled rotating body

Abstract

The invention relates to a device and method for automatically suppressing the milling vibration of a thin-walled rotating body. The device mainly comprises a base, a main shaft, a supporting plate and a vibration damping block and is characterized in that a fixture is fixed to a machine tool through the edge of the base; quick-release pressure plates are evenly distributed at the outer side of the base; the main shaft is arranged at the center of the surface of the base; a rectangular end of a connecting block is fixed to the inner side of the supporting plate by screws, and the cylindrical end of the connecting block is connected to the main shaft through an electric push rod assembly; the electric push rod assembly comprises the front end of a push rod, a push rod sleeve, a motor, a driving gear, an intermediate gear, a driven gear, a lead screw nut and a lead screw; a plurality of rubber shock absorbers are arranged between the supporting plate and the vibration damping block; thecambered surface of the vibration damping block is matched with a workpiece; a roller with a bearing is arranged at the bottom of the vibration damping block; a roller spindle is locked by using the fixed block; and idler wheels are arranged on the supporting plate. The device and method can automatically suppress the milling vibration in the process of processing the thin-walled rotating body, meets the processing quality requirement while satisfying the processing efficiency, and has the characteristics of automation and high precision.

Description

technical field [0001] The invention relates to a milling processing device for a rotary body, in particular to a device and method for automatically suppressing milling vibration of a thin-walled rotary body. Background technique [0002] Large thin-walled rotary parts are widely used in high-end manufacturing fields such as aerospace because of their light weight and good integrity. In the manufacturing process of such parts, milling is usually used to remove up to 80% to 90% of excess material. Due to the low rigidity of the large thin-walled rotary body, cutting vibrations are prone to occur during the machining process, which seriously affects the machining quality. Therefore, in order to complete the milling of such parts and reduce the serious problems caused by cutting vibration, the current method is to reduce the processing parameters, which reduces the cutting vibration but reduces the production efficiency. Therefore, in order to solve the current problems such...
