Aims: This paper aims to develop an automatic testing machine for testing the mutual opening rate of cylinder plugs. Methods: Based on the analysis of transmission characteristics and the feasibility of the positioning of the key, the mechanical structure was designed. Parameters of the main components were determined according to the calculation of the load. Results: The equipment structure and the control system were designed. The main component parameters including the dimensions of the turntable, the model of the screw pair, the torque of each drive motor, etc were calculated. The processing and debugging of the equipment were completed. Conclusions: Through the test of 8 batches of samples, the equipment operates nomally. The test result of the equipment is consistent to the manual test.
