specific Embodiment approach 1

[0009] Specific implementation mode 1. Combination Figure 1 to Figure 3 To illustrate this embodiment, the patch-type longitudinal vibration composite bipedal piezoelectric ultrasonic motor vibrator described in this embodiment includes a metal base 1 and six piezoelectric ceramic sheets 2; the metal base 1 includes a horizontal beam 1-1, two A vertical beam 1-2 and two driving feet 1-3, the left and right ends of the horizontal beam 1-1 are respectively provided with a horizontal horn 1-1-1, each vertical beam 1-2 One end is provided with a vertical horn 1-2-1, and both the horizontal horn 1-1-1 and the vertical horn 1-2-1 are blocks with a rectangular cross-section and gradually tapering; The beam 1-1 and the two vertical beams 1-2 are arranged in a U shape, and the upper end surfaces of the two driving feet 1-3 are respectively connected with the small end surface of a vertical horn 1-2-1; the two driving feet One side of 1-3 is respectively connected with the small end f...

specific Embodiment approach 2

[0011] Embodiment 2. The difference between this embodiment and the patch-type longitudinal vibration composite bipedal piezoelectric ultrasonic motor vibrator described in Embodiment 1 is that the horizontal beam 1-1 and the two vertical beams 1-2 , two driving legs 1-3, three flanges 1-4 and three thin-walled beams 1-5 are composed of a metal base 1 as one piece.

[0012] This embodiment can greatly simplify the manufacturing process of the ultrasonic motor vibrator; the thin-walled beams 1-5 are used to achieve the effects of elastic support and vibration isolation, and can minimize the influence of the connection between the vibrator and other components on the vibration of the vibrator itself.

Description

technical field [0001] The invention relates to a piezoelectric ultrasonic motor vibrator, belonging to the technical field of piezoelectric ultrasonic motors. Background technique [0002] Piezoelectric ultrasonic motor is a kind of piezoelectric ultrasonic motor that uses the inverse piezoelectric effect of piezoelectric ceramics to excite vibration in the ultrasonic frequency range in the elastic body, and forms a particle motion with a specific trajectory at a specific point or area on the surface of the elastic body, and then passes through the stator, The frictional coupling between the rotors converts the microscopic motion of the particle into the macroscopic motion of the rotor. It has the advantages of simple structure, flexible design, low speed, high torque / thrust, high power / torque density, high positioning accuracy, fast response speed, and self-locking when power is off. , No electromagnetic interference and not subject to electromagnetic interference.
