Further, the sensor module 9 includes sensor and positioning plate, and described positioning plate one end is fixed on fixation
On the surface of plate 1, the fixed sensor of the positioning plate other end.
Transmission process and working principle of the invention:
After piezoelectric ceramic motor 2-2 is powered, the top of piezoelectric ceramic motor 2-2 generates up-down vibration, the amplitude of vibration
For 0~0.04mm, vibration frequency is 0~20kHz；Since the structure of motor mounting rack 2-1 is frame shape, therefore motor can be allowed
Mounting rack 2-1 realizes micro stretching and recovery.
When the lower end piezoelectric ceramic motor 2-2 is fixed, the vibration head 5 that piezoelectric ceramic motor 2-2 is withstood upper end is vibrated
First 5 generate up-down vibration simultaneously.This vibration is so that the push-rod assembly being fastenedly connected with vibration head 5 bottom on roller axle 72
It is dynamic, simultaneously because the outer ring of the big unilateral bearing 62 of push-rod assembly and push rod 61 are to realize radial fastening by the first flat key 101
Connection positioning, therefore the outer ring of big unilateral bearing 62 can rotate forward or backward around roller axle 72.
When vibration head 5 moves upwards, the outer ring of big unilateral bearing 62 can rotate forward, due to the big unilateral bearing 62
Outer ring when toward counterclockwise moving is locked with the inner ring of big unilateral bearing 62, and (the characteristics of unilateral bearing is outside bearing
Circle can be freely rotated in one direction relative to bearing inner race, and a kind of bearing locked in the other directions), because
This, the inner ring of big unilateral bearing 62 can rotate forward at this time due to being locked by outer ring, at this time with the inner ring of big unilateral bearing 62
The roller axle 72 being fastenedly connected by second flat key can also rotate forward, while the gear wheel 71 being fastened on roller axle 72 also can
It rotates forward, so that gear wheel 71 drives conveyer belt 8 to feed forward.
When vibration head 5 moves downward, the outer ring meeting back rotation of big unilateral bearing 62, due to the big unilateral bearing 62
Being when outer ring moves in the clockwise direction can be with the inner ring freely relative rolling of big unilateral bearing 62, therefore, big one-way shaft
Hold 62 inner ring will not by outer ring motive force and clockwise rotation, the roller axle being fastenedly connected with big unilateral bearing 62
72 will not stress toward being rotated clockwise；Simultaneously as the outer ring of the small unilateral bearing 73 is relative to inner ring in up time
Needle direction is tightly locked, but the inner ring of small unilateral bearing 73 is fixed in fixed plate 1, therefore the outer ring of small unilateral bearing 73 is
It cannot can not be toward side clockwise toward the roller axle 72 rotationally clockwise, being then fastened on small 73 inner ring of unilateral bearing
To rotation, therefore ensure that the gear wheel 71 being fastened on roller axle 72 also can still stop in situ without back rotation, engagement
Conveyer belt 8 on gear wheel 71 also stays at original position.
As shown in Figure 1, the primary vibration that piezoelectric ceramic motor 2-2 is provided just will push conveyer belt and feed a step forward
Away from this section of distance can be obtained by following calculating: feeding step pitch a=piezoelectric ceramic motor Oscillation Amplitude b × gear wheel of conveyer belt
The acting force arm L of nominal diameter D ÷ vibration.
If the ratio of gear wheel nominal diameter D and the acting force arm L of vibration are 1:1, if the vibration of piezoelectric ceramic motor 2-2 at this time
Dynamic amplitude is 0.01mm, if control carry-over factor f is 1, then the feeding step pitch of conveyer belt 8 is 0.01mm, simultaneously as piezoelectricity is made pottery
The Oscillation Amplitude of porcelain motor 2-2 can continuity adjust, therefore the feeding step pitch of conveyer belt 8 also simultaneously can continuity adjust, therefore, pressure
Micro- amplitude driving of electroceramics motor 2-2 realizes the micro-stepping of conveyer belt 8 and the adjustable feed function of continuity.Pass through pressure again
The vibration frequency control of electroceramics motor 2-2, can be realized the control of 8 feed speed of conveyer belt.This piezoelectric ceramic motor 2-2 is same
When have a feedback servo control system, when gear wheel 71 rotates, sensor can make detection in real time to the position of gear wheel 71 and to piezoelectricity
Ceramic motor 2-2 provides feedback signal, and piezoelectric ceramic motor 2-2 carries out SERVO CONTROL by feedback signal and adjusts to guarantee
The terminal location precision of transmission.In addition, the exportable active force of piezoelectric ceramic motor 2-2 is larger (being up to 720kg),
The active force directly drives transmission terminal, no deceleration mechanism by push-rod assembly, therefore can push biggish load.This patent is set
It counts while design has draught control component, pass through the torsional spring 33 for replacing different spring ratios and replace rubbing for different coefficients of friction
So as to the size of the resistance of adjusting, therefore the different motive force outputs to gear wheel 71 may be implemented in pad 34.
The invention has the following beneficial effects:
1, the present apparatus be utilized piezoelectric ceramic motor Oscillation Amplitude it is small, vibration frequency and amplitude continuity are adjustable
Feature realizes the high-speed drive of the adjustable controllable micro-stepping of speed.
2, the piezoelectric ceramic motor of multi-laminate of the invention has biggish torsional moment, realizes the direct of the big torsion of high speed
Driving.
3, in addition, the simple structure and reasonable design, manufacturing cost are low.
The above description is only a preferred embodiment of the present invention, thus it is all according to the configuration described in the scope of the patent application of the present invention,
The equivalent change or modification that feature and principle are done, is included in the scope of the patent application of the present invention.
