摘要：许多机械传动部件如齿轮在加工的过程中需要严格的保证其加工精度，传统的检测齿轮精度的设备只能在齿轮加工完成后才能对齿轮的精度进行测量，无法在齿轮加工的过程中对齿轮的加工精度进行测量。本文设计了一种齿轮加工在线智能检测装置，能在齿轮加工的过程中对齿轮的轮廓数据进行采集，将机床工作台旋转坐标反馈数据与在线智能检测装置测量的数据进行同步，将检测获得的数据在极坐标下表示即为被加工齿轮齿面检测点的坐标，当被加工工件旋转一周，在线智能检测装置能够测得工件完整的横截面点云坐标。本装置可以有效地实现对加工过程中的齿轮进行测量，具有结构简单、操作快捷、安装方便等优点。

Abstract： Many mechanical transmission parts like gears need to be guaranteed their machining precision when they are in the process of machining.Traditional gear precision detection devices can only measurement the precision of gears after gear cutting is finished， and it is not possible to measure the machining precision of the gear in the process of gear machining.This paper designs a kind of on-line intelligent detection device for gear machining which can collect the profile data of gear when the gear is in the process of processing.and then the feedback data of rotation coordinate of machine tool workbench is synchronized with the data measured by on-line intelligent detection device， and the detected data is represented in polar coordinates as the coordinates of the detection point of the processed gear tooth surface .When the workpiece rotates once， the on-line intelligent detection device can measure the complete cross section point cloud coordinates of the workpiece .This device can effectively measure the machining precision of the gear in the process of gear machining，and has the advantages of simple structure and quick and convenient operation.

许多机械传动部件如齿轮在加工的过程中需要严格的保证其加工精度，传统的检测齿轮精度的设备如三坐标测量机、单啮仪、万能渐开线仪、齿圈径跳仪等只能在齿轮加工完成后才能对齿轮的精度进行测量，无法在齿轮加工的过程中对齿轮的加工精度进行测量，此外这些设备价格高昂、操作繁琐、技术要求高，而在线检测装置能够在零件加工过程中对其进行在线检测，无需卸载零件，避免了零件卸載后不好重新定位的问题，同时使用在线检测装置对加工零件进行在线检测也可以有效地减少被加工两件的误差映射问题[1-5]。……
