Embodiment 1
[0042] Such as figure 1 As shown, a piezoelectric stick-slip driving device with dual drivers sharing the driving foot, including a base 1, a forward piezoelectric driver 2, a reverse piezoelectric driver 3, a flexible hinge shared driving mechanism 4 and Rail module 5; where:
[0043] The forward piezoelectric driver 2 and the reverse piezoelectric driver 3 are connected to the flexible hinge sharing drive mechanism 4 through an adjusting screw 6;
[0044] Adjustment is made by adjusting the screw 6 , so that the shared driving mechanism 4 of the flexible hinge is in contact with the guide rail module 5 .
[0045] More specifically, such as figure 2 As shown, the flexible hinge sharing drive mechanism 4 is an integrated structure.
[0046] More specifically, the flexible hinge sharing drive mechanism 4 includes a circular flexible hinge group 41, a beam flexible hinge group 42 and a connecting structure 43; wherein the circular flexible hinge group 41 is fixedly connected...
Embodiment 2
[0056] More specifically, such as Figure 5 As shown, a driving method of a dual-driver shared drive foot type piezoelectric stick-slip driving device includes the following steps:
[0057] S1: Install and adjust the driving device;
[0058] S2: Input a slowly increasing and rapidly decreasing triangular wave to the corresponding driver according to the driving direction, the driving direction includes forward driving and reverse driving;
[0059] S3: When the voltage rises slowly, the driver stretches slowly, and the flexible hinge sharing drive mechanism 4 produces a forward movement at the driving point and an upward parasitic movement at the same time, clamping the slider 52;
[0060] S4: When the voltage drops rapidly, the driver quickly retracts, and the flexible hinge sharing drive mechanism 4 generates a backward retraction at the driving point and also generates a downward parasitic movement to release the slider 52;
[0061] S5: Continuously input triangular waves ...
Embodiment 3
[0066] More specifically, on the basis of Examples 1 and 2, such as Figure 6 As shown, first assemble the driving device, and its specific working process is as follows:
[0067] Only input a slowly rising and rapidly falling triangular wave voltage to the forward voltage driver 2, its frequency is 1KHz, the voltage is 100V, and the time of rising and falling of the reference voltage is 4:1; when the voltage rises slowly, the forward voltage driver 2 stretches slowly, and the flexible hinge shared driving mechanism 4 produces a forward movement at the driving point and at the same time produces an upward parasitic movement to clamp the slider 52. In this process, the sliding block 52 will move forward along with the driving point of the flexible hinge sharing driving mechanism 4 . Since the voltage is slowly increased and the upward parasitic movement of the driving point will clamp the slider, the slider 52 and the driving point do not produce relative motion, and this proc...
