Key tooth flower identification device

Abstract

The application relates to a device for identifying chipped key teeth. The device for identifying chipped key teeth includes a housing and at least one set of identification components arranged inside the housing. The identification components include blades, a sliding mechanism, a variable resistance device and an identification circuit. The sliding mechanism Made of conductive material. The blade is provided with a key hole and a blocking block, the key hole is used for inserting the key head, and the blocking block is used for controlling the movement of the blade under the extrusion effect of the tooth flower structure when the key head is inserted into the key hole. One end of the sliding mechanism is connected to the blade, and the other end is arranged on the variable resistance device, and can slide relative to the variable resistance device. The first end of the identification circuit is connected to the sliding mechanism, and the second end is connected to one end of the variable resistance device. The identification circuit is used to obtain the electrical parameters representing the actual resistance value of the variable resistance device connected to the identification circuit, so as to calculate through the electrical parameters The teeth of the key head are graded. The key chipping identification device provided in the embodiment of the present application can ensure the accuracy of the number of chippings on the key head.

Description

technical field [0001] The present application relates to the field of lock production and manufacturing, and in particular, to a key tooth flower identification device. Background technique [0002] At present, most keys are processed by milling process, and then the tooth pattern of the key head is obtained by manual measurement. The lock cylinder manufacturing equipment will manufacture the corresponding lock cylinder according to the tooth pattern of the key head. The flower structure is complex and delicate, so that the manual measurement method cannot guarantee the accuracy of the key head tooth flower series, and does not match the manufactured lock cylinder, thereby increasing the lock production cost. SUMMARY OF THE INVENTION [0003] The purpose of the embodiments of the present application is to provide a key tooth flower identification device to solve the above problems. [0004] The key tooth flower identification device provided by the embodiment of the pres...
