Abstract

The invention discloses a strain type integrated three-dimensional turning force sensor. The turning force sensor comprises a sensor body front end, a sensor body rear end, a transverse ten-angle ringelastic sensitive element, a longitudinal ten-angle ring elastic sensitive element and semiconductor resistor strain gauges, wherein the transverse ten-angle ring elastic sensitive element is transversely arranged along the sensor body rear end, the longitudinal ten-angle ring elastic sensitive element is longitudinally arranged along the sensor body rear end, the transverse ten-angle ring elastic sensitive element and the longitudinal ten-angle ring elastic sensitive element are perpendicular, and the transverse ten-angle ring elastic sensitive element and the longitudinal ten-angle ring elastic sensitive element are connected into a whole; the transverse ten-angle ring elastic sensitive element and the longitudinal ten-angle ring elastic sensitive element are connected between the sensor body front end and the sensor body rear end; and the semiconductor resistance strain gauges are adhered to the surface of the transverse ten-angle ring elastic sensitive element and the longitudinalten-angle ring elastic sensitive element. The sensor can accurately measure the three-dimensional cutting force, and is simple in structure, easy to install and high in universality.

Description

technical field [0001] The invention relates to the technical field of intelligent manufacturing equipment, in particular to a strain gauge integrated three-dimensional turning force sensor. Background technique [0002] In recent years, intelligent manufacturing has become one of the main directions of my country's manufacturing industry from "big" to "strong", and high-end CNC machine tools are indispensable intelligent equipment for intelligent manufacturing. During machine tool machining, friction occurs between the turning tool and the workpiece, the cutting ability of the tool will gradually decrease, and the cutting force will gradually increase, which will affect the machining accuracy. Real-time online monitoring of the cutting force generated during the cutting process of the machine tool can adjust the cutting parameters in time, improve the machining accuracy and realize intelligent machining. [0003] To achieve accurate measurement of three-dimensional cutting...
