Abstract

The invention relates to a magnetic vibration exciter which is composed of a connection terminal, a foundation support, a front locking nut, a hollow fastening bolt, a piezoelectric ceramic chip set, a rear locking nut, an energy collection needle, a locking nut, a base, a magnetic isolation ring and an annular brute force magnet. The connection terminal, the foundation support, the front locking nut, the hollow fastening bolt, the piezoelectric ceramic chip set, the rear locking nut, the energy collection needle, the locking nut, the base, the magnetic isolation ring and the annular brute force magnet are assembled from right to left. Charged disassembling and assembling can be achieved by the magnetic vibration exciter, bolt fixation is not needed, the magnetic vibration exciter can be attracted to any iron mechanical mechanism, and the magnetic vibration exciter has the good linearity within the range of 1 KHz to 25 KHz. The magnetic vibration exciter has the advantages of being small in size, light, wide in frequency band response, convenient to assemble and disassemble, good in directionality, high in conversion efficiency, stable in amplitude and long in service life.

Description

technical field [0001] The invention belongs to the technical field of exciters in mechanical manufacturing, in particular to a magnetic force exciter. Background technique [0002] For the exciter at 1-25KHz, among all the exciters so far, there is no broadband miniature exciter that can be installed on the machine without bolting. Contents of the invention [0003] The object of the present invention is to provide a magnetic force exciter in order to overcome the deficiencies of the prior art. [0004] The present invention solves its technical problem and realizes by taking the following technical solutions: [0005] A magnetic exciter, including a connecting terminal assembled from right to left, a base, a front lock nut, a hollow fastening bolt, a piezoelectric ceramic sheet group, a rear lock nut, an energy-gathering needle, a lock nut, The base, the magnetic isolation ring, and the ring-shaped strong magnet, the left end of the hollow fastening bolt is screwed int...
