Abstract

The invention provides an intelligent nut device and a method. The intelligent nut device comprises a flexible plate, mounting blocks are integrally formed at the top and the bottom of an inner cavityof the flexible plate correspondingly, and flexible hinges are integrally formed on the two sides of the top and the two sides of the bottom of the inner cavity of the flexible plate correspondingly.According to the intelligent nut device and the method, through arrangement of the flexible plate, the mounting blocks, the flexible hinges, half-thread nut plates, a mounting seat and piezoelectricceramic drivers, the intelligent nut device is jointly constructed, a bolt is rotated to the interiors of the two half-thread nut plates, when the size of the bolt is smaller than that of a threaded groove formed by the two half-thread nut plates, at the moment, the two piezoelectric ceramic drivers are started to push the two half-thread nut plates to move inwards, due to asymmetry of the flexible hinges, the thread parts at the tail ends moves in the driving direction; and through the stick-slip driving principle, in the screwing process, the half-thread nut plates are driven to be bonded with bolt threads through low-speed driving signals, and then the threads are driven to rotate, so that rapid and automatic pre-tightening is realized.

Description

technical field [0001] The invention belongs to the field of nuts, in particular to an intelligent nut device and method. Background technique [0002] A nut is a nut, a part that is screwed together with a bolt or a screw for fastening. A component that must be used in all manufacturing machinery is divided into carbon steel, stainless steel, and non-ferrous metals (such as copper) according to different materials. Several types, whether the fastening of the precision nut is in place directly affects the accuracy of the screw and the service life of the screw. The precision nut of the screw is a high-precision, high-rigidity fastening element, which is widely used in precision machinery and aerospace equipment Among them, it will provide good conditions for the high efficiency and high speed of the main engine, and the high precision of precision nuts has become an inevitable trend of development. [0003] Among them, the high precision of precision nuts needs to be comple...
