A real-time torque wireless measurement system for machine tool spindle

Abstract

The present invention provides a real-time torque wireless measurement system for a machine tool spindle, including a signal collection and transmission part and a remote monitoring part, wherein: the signal collection and transmission part includes a tool handle assembly, a torque sensor and a card cover installed on the machine tool spindle, The remote monitoring part includes a wireless signal receiving device and a computer processing system. The wireless signal receiving device receives the signal sent by the signal collecting and transmitting part, and transmits the signal to the computer processing system for data management, storage and display. The invention avoids the problem of contact fatigue and wear, and protects the measurement circuit; uses the wireless signal transmission mode based on GPRS, the transmission distance is long, and the transmission data rate is high; Process status management, control and safety warning.

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 ...
