摘要

基于圆柱坐标系测量原理

采用电子展成法研制了一台环面蜗轮滚刀测量机用于环面蜗轮滚刀的快速测量。该测量机通过对3个运动轴的闭环控制

使测头沿着被测误差项的路径运动来获取数据并完成测量。介绍了测量机的工作原理与构成

其为卧式结构

由花岗石床身、精密密珠主轴、滑动导轨和闭环控制系统构成。开发了环面蜗轮滚刀测量软件

实现了环面滚刀各项误差的快速精密测量。实验显示:该仪器可以对切削刃螺旋线误差、刃口齿形误差和容屑槽周节误差进行测量

测量的合成不确定度分别为2.35、2.45和2.94 μm

均小于圆柱齿轮滚刀标准GB/T6084-2001中对应误差项公差的1/3

满足AA级精度的环面滚刀各项误差的测量要求

验证了该测量机的功能与可靠性。该测量机也可以用于环面蜗杆、圆柱蜗杆及圆柱滚刀的测量。

Abstract

By using electronic generative metrology

an hourglass hob measuring machine is developed based on the measuring principle of cylindrical-coordinate system. In the control of three moving axes

the machine allows a probe to move along the measuring path controlled by a closed loop system to obtain the data and implement the measurement. The working principle and constitution of the machine are introduced. The machine is based on a horizontal structure and consists of a granite base

a precision spindle

sliding guides and a closed-loop control system. An hourglass hob measuring software is developed to measure each deviation of the hourglass hob precisely. The practical measurement results indicate that the machine can inspect the cutting edge helix deviation

cutting edge tooth profile deviation and the circular pitch deviation

and the measurement uncertainties are 2.35 μm

2.45 μm and 2.94 μm

less than one third of the tolerances of the deviations in GB/T6084-2001

respectively. It satisfies the requirement of hourglass hobs with accuracy class AA for high precision measuring of each deviation and verifies the function and stabilization of the measuring machine. The machine can measure the hourglass worm

cylindrical worm and the cylindrical hob as well.
