Abstract

The invention discloses a four-channel type piezoelectric steering engine based on an adjustable precompression amplification mechanism. The four-channel type piezoelectric steering engine comprises four rudder wings (1), and is characterized in that the four rudder wings (1) are all connected with corresponding output shafts (19) via bearings (15), each output shaft (19) is installed on an output shaft end fixed rack (16) and connected with one end of a piezoelectric bimorph (12), the other end of each piezoelectric bimorph (12) is connected with an adjustable precompression amplification mechanism (11), the adjustable precompression amplification mechanisms (11) are installed on fixed racks (5) via springs (10), the output shaft end fixed racks (16) and the fixed racks (5) are connected via screws (13), the four output shaft end fixed racks (16) and the four fixed racks (5) are all installed on corresponding discs (6, 20). The four-channel type piezoelectric steering engine is novel in structure, compact, and strong in function practicability.

Description

technical field [0001] The invention relates to a piezoelectric actuator, in particular to an actuator driven by piezoelectric bimorph bending deformation, in particular to a four-channel piezoelectric steering gear based on an adjustable pre-pressure amplifying mechanism. Background technique [0002] Piezoelectric actuator is a new type of electric actuator developed in recent years. It uses the inverse piezoelectric effect of piezoelectric materials to convert electrical energy into mechanical energy. Various actuators with piezoelectric actuators as actuators have been widely used in many technical fields such as micro-displacement platforms, ultra-precision machining, micro-grippers, scanning tunneling microscopes, motion guide rails, antennas, and valves. [0003] Modern warfare has higher and higher performance requirements for guided weapons, and guided artillery shells with fast response and portability, precision strike performance and low cost are coming soon.
