Embodiment Construction

[0010] The gradient piezoelectric ceramic intelligent cutter with self-perception of cutting force of the present invention is fixedly installed on the processing machine tool. When cutting, the dynamic signal generated by the gradient piezoelectric ceramic blade 1 is transmitted to the signal amplification, A / D conversion and wireless transmission circuit integration module 6, the signal processed by signal amplification and A / D conversion is transmitted to signal receiving and processing system 8 through signal wireless transmission 7, and then transmitted to the single-chip microcomputer and host computer connected to it, and the host computer passes through Compensation, decoupling and other calculations are performed on the received data, and then the information of the cutting force in all directions is displayed on the display.

Abstract

The invention provides a gradient piezoelectric ceramic intelligent cutting tool device capable of self-sensing cutting force, belonging to the technical field of machine manufacturing and automation thereof. The gradient piezoelectric ceramic intelligent cutting tool device is characterized in that a gradient piezoelectric ceramic blade 1 is arranged at the foremost end of a square section cutter bar 2; a wire hole communicated with a center hole of the cutter bar is fabricated in the front end of the square section cutter bar; one end of a high-temperature shielding signal line is connected with an electrode of a gradient piezoelectric ceramic blade sensing unit and the other end of the high-temperature shielding signal line is connected with a signal amplification, A / D conversion and wireless transmission circuit integrated module arranged at the rear end of the center hole of the cutter bar; the integrated module wirelessly transmits a collected electric signal to a wireless receiving circuit system; a wireless receiving circuit receives data and transmits the data to an upper computer through a serial communication mode; and the upper computer carries out operation processing of compensation, decoupling and the like and then displays cutting force information in various directions through a display. The gradient piezoelectric ceramic intelligent cutting tool device has the advantages that the structure is simple, the integrated degree is high, cutting force coupling is small, the sensitivity and the detection accuracy are high, and the problem of real-time monitoring of the cutting process in the field of ultra-precision machining can be solved. The figure 1 is a drawing of the abstract.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing and automation thereof, and in particular relates to a gradient piezoelectric ceramic intelligent cutting tool device with self-sensing cutting force. Background technique [0002] At present, the measurement and monitoring of cutting force mainly adopts the traditional cutting dynamometer device. As the most widely used force measurement method at home and abroad, the cutting force gauge has its advantages and some disadvantages. First, the intervention of the cutting force measuring device will inevitably reduce the rigidity of the machining system and affect the overall dynamic performance of the machine tool. Secondly, due to the influence of the volume of the cutting force measuring device, the original parts of the machine tool need to be changed during use, which is not conducive to use and installation, and limits its practical application in precision machining industrial...
