Abstract

The invention discloses an electric spindle device for face grinding. The electric spindle device for face grinding comprises a shell, and is characterized in that a spindle core connected with a face grinding wheel is arranged in the shell and supported by a front end spindle core supporting structure and a rear end spindle core supporting structure; a torque motor used for driving the spindle core to rotate is arranged between the spindle core and the shell; a circulating water cooling channel and a temperature sensor used for detecting the temperatures of the spindle core and the torque motor are arranged on the shell; a grinding fluid channel is formed in the spindle core; and an encoder is arranged at the rear end of the spindle core. The electric spindle device for face grinding has the performance of high precision, rigidity and torque, and the requirements for high torque for low-speed rough cutting and high power for high-speed finish machining of a face grinding machine can be met.

Description

technical field [0001] The invention belongs to end surface grinding machine equipment, in particular to an end surface grinding electric spindle device. [0002] technical background [0003] At present, in the field of end grinding machines, the traditional belt-driven spindle system is usually used. The structure of the belt-driven spindle system is not compact and there are multi-stage transmissions, which leads to a decrease in the efficiency and stability of the spindle. Moreover, the belt drive also has disadvantages such as slipping, vibration and noise at high speeds. [0004] With the increasing demand for ultra-hard and brittle materials in the field of electron optics, the demand for high-precision end grinding of ultra-hard and brittle materials also increases. Due to the large axial grinding force in face grinding and the difficult machining characteristics of superhard and brittle materials, the spindle system is required to have high precision, high rigidity ...
