DEVICE FOR ASSEMBLY OF PIEZO-CONVERTERS Russian patent published in 2022 - IPC H01L41/277 

FIELD: machine tool industry.

SUBSTANCE: invention relates to the field of machine tool industry; it can be used for assembly of piezo-converters of different structures, in particular for compression between each other of piezoceramic elements with electrodes (piezo-package) laid between them. The device for assembly of piezo-converters consists of a case with grips with equipment, fixed on it, and a vertical support pin, on which a carriage with a motor-gearbox is installed. In this case, the device contains a management and control unit performing a function of automatic turning off the motor-gearbox, on a shaft of which a torque adapter is installed for visual control of a compression force of the piezo-converter. At the same time, a hex key is connected to the torque adapter, a stopper coupling is installed under the carriage, made with the possibility of movement along the support pin and limitation of movement of the carriage, and the control unit contains contacts for connection of a digital voltmeter, contacts for connection of electrodes of the piezo-converter, and a switcher of “Measurement – voltage setting” modes.

EFFECT: creation of an effective and easy-to-operate structure of a device, used for compression of a piezo-package.
