Description
Technical field
The utility model relates to brewery's manufacturing equipment technical field, especially relates to one and is applicable to drinks workshop linear piezoelectric actuator.
Background technology
At modern drinks workshop, some electric materials need actuator.Because piezoelectric has superior dynamic property, high-energy-density and increment type stationkeeping ability, so the multinational primary study in the world uses the actuator (piezoelectric actuator) of piezoelectric at present.Compare with traditional electromagnetic actuator, piezoelectric actuator has does not need winding and magnetic circuit, power, positioning precision are high, the advantage such as High power output and fast response time to obtain not rely on electromagnetic coupled.Piezoelectric actuator of a great variety, for being applied to the piezoelectric actuator exporting straight line or rotary motion, can be divided into: piezoelectric ultrasonic motor, Micro Displacement Piezoelectric Actuator for Cutting, piezoelectric inertia actuator and piezoelectricity looper actuator.At present, piezoelectric ultrasonic motor development is comparatively ripe, and Successful utilization is in the fields such as optical apparatus, automobile, Aero-Space and biomedical engineering.Piezoelectric ultrasonic motor have low speed high torque, compact conformation, fast response time, noise extremely low, cut off self-lock, by magnetic interference, the advantage such as accurate of moving and low temperature resistant, the feature such as normally can to run in a vacuum, but piezoelectric ultrasonic motor causes power output less due to the restriction of its principle.The structure of Micro Displacement Piezoelectric Actuator for Cutting is comparatively simply compact, High power output, and positioning precision is high, and dynamic characteristic is good, but impulse stroke is less.Piezoelectric inertia actuator has the feature of high-resolution, Long Distances, but does not have clamping institution to cause power output less with output rigidity, and positioning precision is low.
Utility model content
For overcoming the problems referred to above, the utility model adopts following technical scheme:
One is applicable to drinks workshop linear piezoelectric actuator, this actuator is made up of leading screw, bearing screwed cap, torque motor and drive nut, bearing screwed cap, torque motor and drive nut are connected in turn by flexible clutch, be placed in the inside of shell, the opposite side of drive nut is provided with piezoelectric stack, leading screw is positioned at the center of actuator, through piezoelectric stack, drive nut, flexible clutch, torque motor and bearing screwed cap, one end that leading screw is positioned at actuator inside is provided with ball spline, and piezoelectric stack and ball spline are all placed in the inside of shell.
The helicoid of described leading screw and bearing screwed cap and drive nut is carved angle and is less than 7 °.
The beneficial effects of the utility model are:
This actuator spiral clamping institution only need deflect moment of torsion, does not need deflecting force, can provide deflection moment of torsion, have Long Distances, high thrust, cut off self-lock and the feature such as cost is low conveniently by traditional electromagnetic machine or ultrasound electric machine.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, one is applicable to drinks workshop linear piezoelectric actuator, this actuator is by leading screw 1, bearing screwed cap 2, torque motor 3 and drive nut 4 form, described bearing screwed cap 2, torque motor 3 and drive nut 4 are connected in turn by flexible clutch 5, be placed in the inside of shell 8, the opposite side of drive nut 4 is provided with piezoelectric stack 6, leading screw 1 is positioned at the center of actuator, through piezoelectric stack 6, drive nut 4, flexible clutch 5, torque motor 3 and bearing screwed cap 2, one end that leading screw 1 is positioned at actuator inside is provided with ball spline 7, piezoelectric stack 6 and ball spline 7 are all placed in the inside of shell 8.
The helicoid of described leading screw 1 and bearing screwed cap 2 and drive nut 4 is carved angle and is less than 7 °.
Operation principle of the present utility model is as follows:
During work, after applying piezoelectric stack 6 pumping signal and torque motor 3 initiating signal, piezoelectric stack 6 starts to extend, and upwards pushed up by drive nut 4, drive nut 4 drives leading screw 1 to move upward simultaneously.In this process, leading screw 1 drives bearing screwed cap 2 to move upward, and therefore bearing screwed cap 2 no longer bears load pressure, starts to rotate forward under the drive of torque motor 3, produces the axial displacement towards loading end direction.Because the pressure between drive nut 4 and piezoelectric stack 6 is very large, the frictional force produced prevents drive nut 4 following force torque motor 3 to rotate.
Piezoelectric stack 6 continues to be elongated to maximum elongation position, continues to drive leading screw 1 to move upward.In this process, bearing screwed cap 2 continues to rotate forward under the drive of torque motor 3, until cycle loading end, and the same not following force torque motor rotation because of the frictional force between itself and piezoelectric stack 6 of drive nut 4.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to right.
