　　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.
