摘 要：目前，汽車行業(yè)廣泛采用精密齒輪測量儀對汽車變速箱齒輪精度進(jìn)行測量，在測量過程中進(jìn)行工件裝夾時會產(chǎn)生裝夾誤差，從而導(dǎo)致齒輪精度檢測結(jié)果失真。針對該問題，本文以東風(fēng)格特拉克汽車變速箱有限公司采用的溫澤齒輪測量儀為研究對象，建立了包含工件裝夾誤差的誤差補償模型，研究了工件裝夾誤差模型，提出了一種工件裝夾誤差的測量方法，并對裝夾誤差測量方法及補償效果進(jìn)行了試驗研究，經(jīng)驗證進(jìn)行裝夾誤差補償后工件測量精度得到明顯改善。本文的研究可在較大程度上提升測量儀的使用精度，明顯改善工件的測量精度，保證工件測量結(jié)果的準(zhǔn)確性，對汽車變速箱產(chǎn)品的質(zhì)量保障具有重要的理論意義與現(xiàn)實價值。

Abstract：At present， the automotive industry widely uses precision gear measuring instruments to measure the accuracy of automotive gearbox gears. During the measurement process， clamping errors will occur when workpieces are clamped， which will result in distortion of the gear accuracy detection results. Aiming at this problem， this article takes the Wenze gear measuring instrument used by Dongfeng Trak Automotive Transmission Co.， Ltd. as the research object， establishes an error compensation model including the workpiece clamping error， studies the workpiece clamping error model， and proposes a measurement method of the workpiece clamping error， and the experimental research on the measurement method of the clamping error and the compensation effect have been carried out. After verification， the measurement accuracy of the workpiece is significantly improved after the compensation of the clamping error. The research in this article can greatly improve the accuracy of the measuring instrument， significantly improve the measurement accuracy of the workpiece， and ensure the accuracy of the measurement result of the workpiece. It has important theoretical significance and practical value for the quality assurance of automobile gearbox products.
