Four-shaft harmonic speed reducer numerical control swing head

Abstract

The invention discloses a four-shaft harmonic speed reducer numerical control swing head. The four-shaft harmonic speed reducer numerical control swing head comprises a harmonic speed reducer, a synchronous wheel, a synchronous belt, a driving motor, a connecting plate and an electric spindle, wherein the driving motor is connected with the synchronous wheel through the synchronous belt, the synchronous wheel is connected to the harmonic speed reducer, and the harmonic speed reducer is connected to the electric spindle through the connecting plate. According to the four-shaft harmonic speed reducer numerical control swing head, due to the facts that the driving motor is connected with the synchronous wheel through the synchronous belt, and the synchronous wheel drives the harmonic speed reducer to rotate, vibration of the driving motor at a low speed can be effectively reduced, large output torque can be obtained by the driving motor with small input torque, and accuracy of the numerical control swing head can be improved through small rotation gaps of the harmonic speed reducer.

Description

technical field [0001] The invention relates to a numerically controlled oscillating head, in particular to a numerically controlled oscillating head of a four-axis harmonic reducer. Background technique [0002] The CNC swing head is mainly used to control the swing axis of the tool, and the machining angle of the tool is changed by the swing of the swing head. However, many CNC equipment control the swing of the swing head through a general reducer at present, and the transmission accuracy is often not very good, and the transmission is relatively small. The vibration of the motor cannot be reduced, the output torque is not high, and it is difficult to ensure the accuracy of the workpiece. Contents of the invention [0003] A numerical control oscillating head of a four-axis harmonic reducer, including a harmonic reducer, a synchronous wheel, a synchronous belt, a transmission motor, a connecting plate, and an electric spindle, characterized in that: the transmission mot...
