Plane scroll spring (winding) as a power source or storage elements are widely applied to the timer, watches, electrical and other products. As part of the winding heart, we must stabilize the output of its torque and reliable working life of their products designed to meet the requirements. Therefore, in winding production process and factory inspection, it is essential to its output torque and work life of rigorous testing to ensure that the quality of reliability. Spring winding manufacturers for each batch of spring winding to conduct random testing. Torque tests content, including testing and fatigue testing. The current domestic corresponding test equipment intelligent, and the degree of automation is not high, torque and fatigue tests to be conducted separately, need two sets of equipment, which requires the integration of intelligent spring winding torque and fatigue test instrument.
Spring papers on the detection of principle, design a spring torque and fatigue testing system. Design based on Matsushita (Fp Σ-c32) PLC, Proface touch screen (GP37W2), the West in aircraft electrical and mechanical sensors CYB-803S, the spring servo motor torque and fatigue testing systems, as long as the spring loaded test measured Taiwan, Will be able to automatically torque and fatigue test. System can be based on different requirements, changes of parameters, to achieve different purposes. This design also uses a touch screen as a human-computer interface, through the touch-screen operation can be carried out set of parameters, to achieve the various functions of control, while through the touch screen display test results and the system is currently running real-time monitoring.
Key words： spring torque, fatigue testing, PLC, touch screen,
