1. the two-way precision conveying device of single excitation ultrasonic elliptical vibratory, comprises mover and stator, it is characterized in that:

  • mover comprises transport tape, belt wheel and is arranged on the frictional layer of band wheel side;

    The single-excitation ultrasonic oval vibration energy converter that stator comprises support, fixed by support two identical, the friction-driven block that two identical elliptical vibration modal transducer are identical with two;

    Described single-excitation ultrasonic oval vibration energy converter entirety is in cylinder, it comprises bolt and is set in back shroud, piezoelectric ceramic piece, electrode slice and the front shroud on bolt successively, front shroud is provided with the ring flange that can connect with other constructional device, back shroud, piezoelectric ceramic piece, electrode slice and front shroud are connected compression by bolt by back shroud and front shroud;

    Described elliptical vibration modal transducer is arranged on the front end of front shroud, described elliptical vibration modal transducer comprises the composite construction of straight beam and cant beam formation, straight beam and cant beam are rectangle perpendicular to the cross section of its central axis, the central axis of straight beam and the central axes of single-excitation ultrasonic oval vibration energy converter, one end of straight beam connects with the front shroud of ultrasonic transducer, and the other end overhangs;

    The side of one end of cant beam and the front shroud displaced central axis line of ultrasonic transducer connects, the middle part of the other end and straight beam connects, the central axis of cant beam becomes 0-90 degree angle with the central axis of straight beam, and straight beam and cant beam are arc transition with the connection place of ultrasonic transducer front shroud and connect;

    Two described friction-driven blocks are separately positioned on the front end of two elliptical vibration modal transducer, tangent with the frictional layer that arranges of band wheel side and contact;

    Single-excitation ultrasonic oval vibration energy converter axis after ring flange is fixed with support becomes the angle of 20 degree ~ 160 degree with belt wheel plane.
