Problems solved by technology

[0004] The purpose of the present invention is to solve the problems existing in the prior art, that is, the existing real-time monitoring means, due to the complexity of the detection equipment, high cost, large volume, inconvenient use, damage the completeness of the precision processing equipment, resulting in a decline in the performance of the machine tool processing equipment , limited by its own dynamic characteristics and resolution parameters, and based on the existing detection methods, it can only reflect the cutting process of the overall tool, but it is difficult to detect the cutting area, tool tip and cutting vicinity of the tool. Restricts the real-time monitoring ability of tiny cutting force, vibration and temperature changes in ultra-precision machining

Abstract

The invention provides an intelligent tool based on a surface acoustic wave sensing system. A diamond tool bit is fixed at the front end of a tool blade of the intelligent tool, a tool blade signal sensing area is formed on a portion of the tool blade, on the back of the diamond tool bit, and the surface acoustic wave sensing system is fixed in the tool blade signal sensing area on the tool blade. According to the intelligent tool based on the surface acoustic wave sensing system, the situation that a tool is only used for achieving a signal actuator function of cutting machining in the prior art is broken, and the tool intelligence change to a sensor capable of self monitoring in real time is achieved; the problems that equipment is complicated, price is high, size is large, installation and structure sizes are limited, performance of ultra-precise equipment is destroyed, practicality is poor, requirements of ultra-precision machining monitoring on measurement precision and sensitivity can not be met, and the like in a prior monitoring sensing system are solved; and the intelligent tool based on the surface acoustic wave sensing system has the advantages of being simple and compact in structure, high in integration degree, convenient and easy to use, high in practicality, and high in measurement precision and sensitivity, and cutting temperature and cutting force of the tool can be monitored in real time.

Description

technical field [0001] The invention relates to an intelligent tool based on a surface acoustic wave sensing system, belonging to the technical field of intelligent tools. Background technique [0002] The surface acoustic wave sensor is made by utilizing the characteristic that the surface acoustic wave propagation performance changes with the external conditions on the surface of the piezoelectric substrate. The characteristics of the surface acoustic wave sensor are used to be sensitive to the disturbance of external physical quantities (such as stress, temperature, flow and acceleration, etc.). Changes in external physical quantities will cause changes in the propagation speed of surface acoustic waves, thereby causing changes in resonance frequency and phase. Through accurate Measure frequency change and phase change to measure the change of physical quantity. The surface acoustic wave sensor's high precision, high sensitivity, good linearity, wireless and passive char...
