摘　　要：针对以往的热膨胀位移传感测量装置存在着固有的缺陷，本课题采用高精度光栅位移传感器与微计算机，建立了点焊过程热膨胀电极位移实时检测系统。大量试验结果表明：该检测系统能方便、可靠地测取点焊过程中的热膨胀电极位移，具有精度高、速度快等特点，可用于点焊过程质量控制。文章介绍了该检测系统的硬件组成与软件设计。To solve the inherent shortcomings in the former heat inflation displacement sensor, a real time detection system of electrodes displacement due heat inflation in spot welding process has been developed based on the high resolution grating displacement sensor and micro processor. The experimental results prove that this system senses the displacement in process simply and reliably with high resolution and high speed and can be used in quality control in spot welding process. This article introduces the hardware composition and software design of this system as well as experimental results and analysis.
