The invention discloses a motorized spindle cooling device with a temperature self-detection function. The motorized spindle cooling device comprises a shell with a motorized spindle channel, a heat exchanging medium channel is formed in the shell, cooling balls and sensing balls matched with the heat exchanging medium channel in a rolling mode are arranged in the heat exchanging medium channel, each cooling ball comprises a hollow ball body and phase change materials arranged in the hollow ball body in a filling mode, and the sensing balls are used for detecting the temperature of the heat exchanging medium channel. The cooling balls solve the cooling liquid leakage problem which is caused by a sealing problem in the prior art; through a screw rod and a drive channel, the cooling balls and the sensing balls can move in the heat exchanging medium channel in a circulating mode; through the acoustic surface wave sensing technology, acoustic surface wave sensor sensitive elements are wrapped in the outer shell to form the sensing balls, so that wireless and passive long-acting monitoring on the cooling effect is achieved; the sensing balls roll in the heat exchanging medium channel in a circulating mode, and compared with a traditional measurement method, the number of sensors can be reduced, and full-channel dynamic temperature monitoring is achieved.
Description
technical field [0001] The invention relates to a cooling device, in particular to a temperature self-detecting electric spindle cooling device. Background technique [0002] The electric spindle is a new technology that has appeared in the field of CNC machine tools in recent years and integrates the machine tool spindle and the spindle motor. It makes the main drive system of high-speed CNC machine tools cancel the belt drive and gear drive, and realizes the "zero transmission" of the machine tool. Together with linear motor technology and high-speed cutting tool technology, the electric spindle pushes high-speed machining into a new era and plays a pivotal role in the field of high-efficiency machining. A large number of studies have shown that the heating of the spindle is one of the most important factors affecting its performance (stiffness, precision, and service life), and the thermal error of the spindle caused by it is the largest source of error in precision machi...
