摘要：許多機械傳動部件如齒輪在加工的過程中需要嚴格的保證其加工精度，傳統的檢測齒輪精度的設備只能在齒輪加工完成后才能對齒輪的精度進行測量，無法在齒輪加工的過程中對齒輪的加工精度進行測量。本文設計了一種齒輪加工在線智能檢測裝置，能在齒輪加工的過程中對齒輪的輪廓數據進行采集，將機床工作臺旋轉坐標反饋數據與在線智能檢測裝置測量的數據進行同步，將檢測獲得的數據在極坐標下表示即為被加工齒輪齒面檢測點的坐標，當被加工工件旋轉一周，在線智能檢測裝置能夠測得工件完整的橫截面點云坐標。本裝置可以有效地實現對加工過程中的齒輪進行測量，具有結構簡單、操作快捷、安裝方便等優點。

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.

Key words： gear machining;on-line intelligent detection;linear module

許多機械傳動部件如齒輪在加工的過程中需要嚴格的保證其加工精度，傳統的檢測齒輪精度的設備如三坐標測量機、單嚙儀、萬能漸開線儀、齒圈徑跳儀等只能在齒輪加工完成后才能對齒輪的精度進行測量，無法在齒輪加工的過程中對齒輪的加工精度進行測量，此外這些設備價格高昂、操作繁瑣、技術要求高，而在線檢測裝置能夠在零件加工過程中對其進行在線檢測，無需卸載零件，避免了零件卸載后不好重新定位的問題，同時使用在線檢測裝置對加工零件進行在線檢測也可以有效地減少被加工兩件的誤差映射問題[1-5]?！?br>
