Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
The supersonic motor that embodiment of the present utility model is applied, system architecture as shown in Figures 2 to 5, including lower turn
Son 1, the center of a side surface of lower rotor part 1 is provided with assembled shaft 2, and stator 3 and upper rotor part 4, and stator 3 are arranged with assembled shaft 2
Between upper rotor part 4 and lower rotor part 1；Upper rotor part 4 is provided with shell fragment 5 away from a side surface of stator 3, and assembled shaft 2 is away from lower turn
One end of son 1 is provided with the fixture block 6 for extending in a radial direction, and the assembling for allowing assembled shaft 2 and fixture block 6 to pass through is offered on shell fragment 5
Hole 51, when shell fragment 5 is in free state, between the gap between fixture block 6 and lower rotor part 1 is less than between shell fragment 5 and lower rotor part 1
Gap, after fixture block 6 passes pilot hole 51 and rotated relative to shell fragment 5, fixture block 6 can be to the direction extrusion elastic near lower rotor part 1
5。
The supersonic motor that the utility model embodiment is provided, one end that fixture block 6 is provided with assembled shaft 2 sequentially passes through calmly
After being passed in son 3 and upper rotor part 4, and pilot hole 51 from shell fragment 5, fixture block 6 turns an angle relative to shell fragment 5, can make
Fixture block 6 is close to a side surface extrusion elastic 5 of shell fragment 5, and now shell fragment 5 can produce the deformation towards lower rotor part 1, due to the ultrasound
The ripple motor restoring force that stator is produced after stationary state, therefore the deformation of shell fragment 5 in use can press to upper rotor part 4
Stator 3, meanwhile, the restoring force produced after the deformation of shell fragment 5 can be transferred to lower rotor part 1 by assembled shaft 2, make lower rotor part 1 to stator 3
Position extrudes, so that the lower rotor part 1 and upper rotor part 4 of the supersonic motor produce certain chucking power to stator 3, so as to
To be vibrated in stator 3 and transmitted, so that rotor is rotated.Successively be arranged for stator 3 and upper rotor part 4 in assembling by the supersonic motor
In assembled shaft 2, contacted and extrusion elastic 5, group with shell fragment 5 after fixture block 6 is turned an angle relative to shell fragment 5
It is short the time required to dress.And because the supersonic motor in assembled shaft 2 without being additionally processed, thus assembled shaft will not be reduced
2 intensity and difficulty of processing is low.
When upper rotor part 4 is with 5 rotation process of spring plate, shell fragment 5 directly produces frictional force with the contact surface of fixture block 6, this part
Frictional force includes making shell fragment 5 and fixture block 6 keep the stiction of geo-stationary, also including making what fixture block 6 was moved relative to shell fragment 5
Kinetic force of friction, when the kinetic force of friction between shell fragment 5 and fixture block 6 is more than stiction, fixture block 6 occurs relative to shell fragment 5
Mobile, when fixture block 6 is moved at pilot hole 51 relative to shell fragment 5, fixture block 6 disappears to the squeezing action of shell fragment 5 so that rotor
Chucking power to stator is disappeared, and stator 3 cannot be transmitted these vibrations on rotor, cause the supersonic motor cisco unity malfunction.
Be the generation for avoiding this case, as shown in Figures 3 to 6, offer spacing hole 52 on shell fragment 5, fixture block 6 towards shell fragment 5 one
Spacing preiection 7 is provided with side surface, after spacing preiection 7 is rotated with fixture block 6 relative to shell fragment 5, can be connected in spacing preiection 7
In spacing hole 52, to prevent fixture block 6 relative to the rotation of shell fragment 5.After spacing preiection 7 is connected in spacing hole 52, if shell fragment 5 with
When kinetic force of friction between fixture block 6 is more than stiction, then fixture block 6 produces the trend moved relative to shell fragment 5, but due to spacing
Raised 7 are connected in spacing hole 52, and the hole wall of spacing hole 52 leans with the side wall of spacing preiection 7 so that spacing preiection 7 can not
It is enough to be moved relative to fixture block 6, and then define the movement relative to shell fragment 5 of fixture block 6, it is to avoid there is the supersonic motor in fortune
There is the situation of shutdown because chucking power disappears during turning.
Through after rotating to an angle after pilot hole 51, the lower surface extrusion elastic 5 of fixture block 6 makes shell fragment 5 produce shape to fixture block 6
Become, and the deformation that shell fragment 5 is produced is crossed conference and causes the elastic deformation of shell fragment 5 to be changed into plastic deformation, the position of deformation occurs not
Can reply and fracture even occur, to avoid this case, as shown in Figure 3 and Figure 6, shape and fixture block 6 and the assembling of pilot hole 51
The cross sectional shape radially of axle 2 is adapted.The shape of pilot hole 51 is transversal with the combining structure of fixture block 6 and assembled shaft 2
The shape in face is adapted, and now, after the combining structure of fixture block 6 and assembled shaft 2 passes through pilot hole 51, fixture block 6 rotates arbitrarily angled
Can ensure that fixture block 6 is maximum near a side surface of shell fragment 5 and the contact area of shell fragment 5, and fixture block 6 is squeezed to the generation of shell fragment 5
Pressure size is constant, thus average smaller to the pressure in the unit area of the contact surface of shell fragment 5, with the contact of fixture block 6 on shell fragment 5
The deformation that face produces is smaller, and being not in that the deformation of shell fragment 5 is excessive cannot reply situations such as being even broken, it is ensured that ultrasonic wave electricity
The steady operation of machine.
Fixture block 6 is preferably 90 ° through the anglec of rotation after pilot hole 51, as shown in Figure 6 and Figure 7, namely pilot hole 51
Bearing of trend it is vertical with the bearing of trend on the edge of spacing hole 52.If fixture block 6 is smaller through the anglec of rotation after pilot hole 51, spacing
Spacing between hole 52 and pilot hole 51 is smaller, and this causes that fixture block 6 is in extruding after spacing preiection 7 is connected in spacing hole 52
During shell fragment 5, the deformation that the shell fragment 5 near the side of pilot hole 51 is produced is larger, and this load of part shell fragment 5 is larger, the deformation of generation
It is larger, easily there is plastic deformation and be even broken.And when the anglec of rotation after fixture block 6 passes through pilot hole 51 is larger, although no
Shell fragment 5 can be caused to occur compared with large deformation or fracture, but due in assembling process fixture block 6 relative to shell fragment 5 rotation more use
It is accomplished manually, the rotation human body wrist of larger angle cannot once rotate in place, need to carries out by several times, assembling takes time and effort.And incite somebody to action
After fixture block 6 is set to 90 ° through the anglec of rotation after pilot hole 51, shell fragment 5 is not in that plastic deformation is even broken, and is rotated
Angle more meets ergonomics, and operating personnel can once be rotated in place in rotation process.
After the extrusion elastic 5 of fixture block 6 makes shell fragment 5 produce elastic deformation, the restoring force of shell fragment 5 is in grip 3 and rotor
Meanwhile, also there is certain squeezing action to fixture block 6, to avoid shell fragment 5 from fixture block 6 is taken off with assembled shaft 2 to the squeezing action of fixture block 6
Open, as shown in Figure 4 and Figure 5, multiple fixture blocks 6 are arranged at intervals with the same cross-sectional circumferential of assembled shaft 2, so that shell fragment 5 is produced
Raw restoring force is respectively acting on different fixture blocks 6, and the stress on single fixture block 6 is smaller, is difficult to disengage.
When the extrusion elastic 5 of fixture block 6 clamps stator 3 and rotor, the deformation that the shell fragment 5 at fixture block 6 is produced is bigger,
Elastic deformation also implies that more greatly chucking power is bigger, for motor rotation is unstable caused by avoiding chucking power skewness, such as Fig. 5
Shown, multiple fixture blocks 6 are uniformly distributed in assembled shaft 2, and the deformation distribution that now 6 extrusion elastic of fixture block 5 is produced is more uniform, no
Occur on shell fragment 5 that localized positions deformation is excessive and the too small situation of another part deformation, effectively ensure that supersonic motor
Steady running.
It is preferred that the rectangle fixture block that fixture block 6 is set to extend along the radial direction of assembled shaft 2, as shown in Figures 4 to 7, square
The difficulty of processing of shape fixture block is low and can increase the contact area between fixture block 6 and shell fragment 5, can effectively reduce the list of contact surface
The upper suffered pressure of plane product, it is to avoid shell fragment 5 plastic deformation occurs and is even broken.
Pilot hole 51 and spacing hole 52 are offered on shell fragment 5, in order to the assembling of the supersonic motor, but shell fragment 5 is opened
The intensity of the bigger shell fragment 5 of hole area is lower, and shell fragment 5 is easier during use plastic deformation even appearance fracture occurs,
To avoid this case, two pieces of fixture blocks 6 are only provided with assembled shaft 2, as shown in Figures 3 to 5, this two pieces of fixture blocks 6 are in assembling
It is uniformly distributed in the same cross-sectional circumferential of axle 2, this causes that the perforated area on shell fragment 5 is smaller, but is able to ensure that suffered by shell fragment 5
To extruding force be evenly distributed, do not interfere with the normal work of the supersonic motor.
It is arranged on spacing preiection 7 of the fixture block 6 on shell fragment 5 one side surface in use, its side and spacing hole
52 hole wall interacts, so as to fixture block 6 be defined with the relative position of shell fragment 5, but the side of spacing preiection 7 with it is spacing
During interaction, spacing preiection 7 can be acted on the hole wall in hole 52 with the connecting portion of fixture block 6 by concentrated stress,
To avoid spacing preiection 7 from being disengaged with fixture block 6, as shown in figure 5, spacing preiection 7 is fitted near the side of assembled shaft 2 with assembled shaft 2
Fixed, this causes that spacing preiection 7 is connected with fixture block 6 incessantly, is also connected with assembled shaft 2 that spacing preiection 7 is made by concentrated stress
Used time is not easy to come off.
Fixture block 6 is disengaged with spacing preiection 7 or fixture block 6 is disengaged with assembled shaft 2, all can have influence on the supersonic motor just
Often operating, to avoid the appearance of this case, as shown in figure 5, fixture block 6, spacing preiection 7 and assembled shaft 2 are integrally formed, one
Moulding process avoids Joining Technology, and processing step is reduced to a certain extent, and integral forming process causes fixture block 6, limit
Position raised 7 and assembled shaft 2 turn into a global facility, and the bonding strength between each structure is higher.
Other compositions of supersonic motor on the utility model embodiment etc. are for those skilled in the art is ripe
Know, no longer describe in detail herein.
