碩士 === 國立臺北科技大學 === 製造科技研究所 === 103 === This thesis presents a novel design of mechanical testing device for the lock cylinder to check its expected life. It mainly consists of linkage, key fixture and lock fixture. The required mechanism design is based on an ordinary key’s turning-angles required to unlock, which are 90˚,180˚and 270˚, as the motion range of the required output link. The resulted design is a six-bar linkage which can perform three different output turning-angles by changing one of its link for testing three different lock cylinders. The solid model of this novel design has been done via Solidworks software, and its kinematic simulation is also performed as well. The prototype of this inspection device has been fabricated and tested. The preliminary result confirms the feasibility of the design.
