[Abstract]:In view of the difficulty of measuring the straightness error of hydraulic cylinder parts, a method of determining the axis straightness of hydraulic cylinder by measuring the chord length of hydraulic cylinder section is presented. The laser is used as the reference line for straightness error evaluation. A straightness detecting device based on pneumatic detection and laser collimation is designed, the pneumatic detection scheme based on the nozzle surface baffle model is analyzed, and the spatial position of PSD position sensitive sensor is analyzed. The method of separating error by using PSD position sensitive sensor is put forward, and the straightness error is detected by using this device, the process of detection is stable and can meet the requirements.
