The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments. Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals. Referring to FIG. 2, a first preferred embodiment of the piezoelectric oscillating device of the present invention comprises a base 2, an actuating member 3 disposed on the base 2, and a cover member 3 attached to the actuating member 3. a grinding machine 41, a first output member 5 connected to the base 2, and a second output member connected to the base 2, the polishing sheet 41 having an exposed rough surface 411, and the first output 5 includes - a rear cover 51 attached to the base 2, opposite to the rear cover ^ and connected to the actuating member 3 (4) a front cover 52, disposed between the cover 52 rear cover 4 M420364 5i and The first piezoelectric member 53 made of a piezoelectric material, and two are disposed between the front cover 52 and the first piezoelectric member 53, and the insulating sheet 54 between the rear cover 51 and the piezoelectric member 53. The second output member 6 includes a rear cover 6 pivotally connected to the base 2, a front cover 62 opposite to the rear cover 61 and connected to the actuating member 3, and is disposed on the front cover 62 and the rear cover 62 A second pressing member 63 between the covers 61 and made of a piezoelectric material; between the front cover 62 and the second piezoelectric member 63, and the rear cover 61 and the second piezoelectric member 63 are respectively disposed between the front cover 62 and the second piezoelectric member 63. Between the insulation sheets 64. See Figure 2 and match Referring to Figure 3, since the piezoelectric material has the characteristic of mutual conversion between the electrical energy of the mechanical energy disk, an electric field is applied to the surface of the piezoelectric material, and the piezoelectric material is deformed in the direction of the electric field to resist elongation or shortening. The first piezoelectric element 53 receives the -th control signal to deform, and the front cover 52 pushes the actuating member 3 to reciprocate in a first direction, and the insulating sheet 54 of the first wheel-outlet 5 makes the When the first piezoelectric element 53 is connected to the first control signal 71, it is not transmitted to the front cover η or the back cover 51 ′, and the external (4) can be prevented from tilting the fourth (four) signal 71 to maintain the accuracy of the first control signal 71. Similarly, the second piezoelectric member 63 is deformed by receiving a second control signal 72, so that the front cover 62 pushes the actuator 3 to reciprocate in the second direction, and the second output member 6 is insulated. The piece 64 also causes the second piezoelectric element 63 to receive the second control signal 72 without being transmitted to the cover 62 or the back cover 6 to prevent the external signal from interfering with the second control number 72, maintaining the second control.

The material used should not be limited to this. Refer to Figure 3' and cooperate with Figure 4~7' when the _ control signal 71:: 讯 幻 2 points to the _ output 5 ( ΓΛ Γ 2) 'such as the Chinese object _ waiting, the first One control = band is zero' and the second control signal 72 is at a maximum value, so the first piezoelectric member 53 is not deformed' and the second piezoelectric member 63 is deformed to the longest, so that the actuating member 3 is moved as shown in the figure 4, then, the time from & point to point b, 'the first piezoelectric member 53 will gradually elongate' and the second piezoelectric member ^ will gradually return to the length without deformation, so that the actuating member 3 After moving to the position ' as shown in FIG. $, when the time is from point b to point c, the first piezoelectric member 53 gradually returns to the length without deformation, and the second piezoelectric member 63 is gradually reduced to the shortest ' The actuating member 3 is moved to the position shown in FIG. 6. Finally, when the time is from c to d, the first piezoelectric member 53 is contracted to the shortest, and the second piezoelectric member 63 is set back to the length without deformation. The actuating member 3 is moved to the position shown in Fig. 7. Thus, in one cycle, the actuating member 3 is moved in a circular plane, so that it can be applied to the actuating member 3.

Therefore, the M420364 can be adjusted to different speeds to meet different types of grinding and polishing requirements. In addition, if the waveforms of the first control signal 71 and the second control signal 72 are changed, the actuator 3 The oscillating path is correspondingly changed. For example, if the waveforms of the first control signal 71 and the second control signal 72 are changed to the waveforms as shown in FIG. 8, the actuator 3 will reciprocate in an oblique straight line. The same can be used for grinding and polishing. Referring to FIG. 9, a second preferred embodiment of the piezoelectric oscillating device of the present invention is substantially the same as the first preferred embodiment.
