摘要
进口车削力测量仪价格昂贵,本文研制一种车削力测量仪,采用了单片机、HX711模数转换器、串口通信芯片等组成测量电路,实时将应变片测量的车削力传送给计算机,计算机绘制出车削力曲线图.该车削力测量仪可完成参数设置、传感器的标定、自动调零、数据保存,操作简单、界面直观,且价格便宜,已经用于本科生的课程实验.
Imported turning force measurement instruments are highly expensive.This paper designs and develops a turning force measurement instrument,in which the measuring circuit is formed using single chip microcomputer,HX 711 analog-to-digital converter and serial port communication chip to transmit the turning force measured by strain gauge to the computer in real time and draw the turning force curve.This instrument can complete parameter setting,sensor calibration,automatic zero setting and data storage.Cheap and easy to handle with intuitive interface,it has been put into use in experiments in college education.
