Wireless measuring system for real-time torque of machine tool spindle

Abstract

The invention provides a wireless measuring system for a real-time torque of a machine tool spindle. The system comprises a signal acquiring and transmitting part and a remote monitoring part, wherein the signal acquiring and transmitting part comprises a knife handle assembly, a torque sensor and a locking hood which are installed on the machine tool spindle; the remote monitoring part comprises a wireless signal receiving device and a computer processing system. The wireless signal receiving device is used for receiving signals sent by the signal acquiring and transmitting part and transmitting the signals to the computer processing system for data management and storage and display. According to the system provided by the invention, the problem of contact fatigue wear is avoided and a measuring circuit is protected. By adopting a wireless signal transmission mode based on GPRS, the transmission distance is long and the transmission data rate is high; change of the torque signal in the technical process is monitored by a remote monitoring system in real time, so that the state management, control and safe pre-warning of the technical process are achieved.

Description

technical field [0001] The invention relates to the field of machine tool processing monitoring in mechanical processing, in particular to a real-time torque wireless measurement system for a machine tool spindle. Background technique [0002] In the process of machine tool processing, the processing status of the machine tool can be understood in real time through the detection of the torque signal of the machine tool spindle, which provides a basis for formulating and optimizing process parameters and fault warning in the process of processing. How to transmit the measured torque signal of the rotating shaft is the focus of torque measurement. At present, wired and wireless methods are widely used to transmit torque signals. The wired method is represented by slip rings, but the use of slip rings limits the rotational speed of the shaft. , there are problems such as rotating contact fatigue wear, and there is line length interference. Ways of wireless torque transmission ...
