Precise Intermittent Motion Mechanism Intelligent Test System

As an important part of automatic mechanism, precise intermittent movement mechanism plays an unreplaceable role in the development of current industry. Due to its manufacturing precision and life-span, intermittent movement mechanism becomes bottle-neck in the improvement of technical performance. Apart from the feasible design and manufacturing precision of the mechanism, the product has to be precisely measured and tested. In order to obtain the movement property of precise intermittent movement mechanism, the linear displacement, veldcity and acceleration have to be measured individually. It has been shown that the traditional measuring procedure is complcx and cannot frilly eliminate the distortion. By contrast, the prominent angular displacement output of the precise intermittent movement mechanism has been considered in this thesis. An effective testing system has been designed from a new point of view, which simplifies the measuring and data processing. The measuring system is designed to be high precise, automatic and intelligent based on a computer control system which can collect and transit data by rotating induction synchronizer and digit-readout system. A user friendly software -package has been designed which can be used in data acquisition and processing, and control the rotation of the step-motor of tested intermittent movement mechanism. Rotating induction synchronizer and digit-readout system are the main parts of the designed measuring system, and have the decisive effect on the measuring accuracy. The concentricity of stator and rotor on rotating induction synchronizer affects testing result significantly, thus an intelligent and precise mechanism on rotating induction synchronizer has been designed to adjust concentricity. It has been shown that the designed measuring system can also be used to test other angular displacements by simply modification of the system.
