Direct-connected connect.
Motor 20 is fixed on the side away from the second supporting part 12 for first supporting part 11, and contiguous block 30 is at least partially disposed in
Between one supporting part 11 and the second supporting part 12, and contiguous block 30 is supported by the second supporting part 12.Actuated element 40 is located at even
Connect the side away from the first supporting part 11 for the block 30.Motor 20 drives actuated element 40 to rotate by contiguous block 30.
Referring to Fig. 2 and Fig. 3, the first supporting part 11 offers first through hole 111 and multiple locking hole 112, multiple
Locking hole 112 is located at the surrounding of first through hole 111.Second supporting part 12 offers the second through hole 121 and multiple resigning hole 122,
Second through hole 121 is corresponding with first through hole 111, and multiple resigning holes 122 are corresponding with multiple locking holes 112 respectively.This transmission
Mechanism 100 also includes multiple securing members.
Motor 20 includes driving main body 21 and rotating shaft 22.Securing member is arranged in locking hole 112 so that main body 21 will be driven solid
On this first supporting part 11, securing member has certain gap with the inner surface of locking hole 112.When solid using spanner locking
During part, resigning hole 122 is used for passing through the second supporting part 12 for spanner.Rotating shaft 22 is connected with driving main body 21, for driving master
The driving lower band of body 21 block 30 that is dynamically connected rotates.Rotating shaft 22 is arranged in first through hole 111, and protrudes from the first supporting part 11
On surface.In the present embodiment, motor 20 is micromachine 20.
Contiguous block 30 includes body 31 and the driving section 32 being formed from the middle part of body 31 along the axis extension of body 31.This
Body 31, between the first supporting part 11 and the second supporting part 12, is in substantially hexa-prism.The center of body 31 offers connection
Hole 311, in the present embodiment, connecting hole 311 is generally circular, and the inner surface of connecting hole 311 includes stopper section 3111, backstop
Portion 3111 is plane, in case rotation stop axle 22 is relatively rotated with contiguous block 30.Rotating shaft 22 is arranged in connecting hole 311, and be connected
The inner surface in hole 311 has default distance, is connected by the way of the cooperation of gap between rotating shaft 22 and connecting hole 311.
In the present embodiment, the monolateral gap between rotating shaft 22 and connecting hole 311 is about 0.4 millimeter (mm).And, and rotating shaft 22
Gap and connecting hole 311 between is more than the gap between securing member and locking hole 112.
Driving section 32 is arranged in the second through hole 121 and protrudes from the surface away from the first supporting part 11 for second supporting part 12
On, driving section 32 is connected with actuated element 40.In the present embodiment, driving section 32 is hexa-prism.Driving section 32 and
The inner surface of two through holes 121 is spaced default distance, adopts the side of gap cooperation between driving section 32 and the second through hole 121
Formula.In the present embodiment, the monolateral gap between driving section 32 and the second through hole 121 is about 0.005mm.Due to driving section
32 and second the inner surface of through hole 121 there is gap, driving section 32 can rotate relative to motor fixing plate 10.
Actuated element 40 is substantially cylindrical, and the center of actuated element 40 offers receiving hole 41, the transmission of contiguous block 30
Portion 32 is inserted in receiving hole 41, so that contiguous block 30 can be connected to transmitting torque with actuated element 40.In present embodiment
In, receiving hole 41 is hexagon ring.Actuated element 40 is used for connecting a processing unit (plant), such as grinding head, but not limited to this.
During assembling, first contiguous block 30 is positioned on the second supporting part 12, and motor 20 is fixed on motor fixing plate
On 10, make the connecting hole 311 gap cooperation of rotating shaft 22 and contiguous block 30.Then, by the transmission of actuated element 40 and contiguous block 30
Portion 32 is connected.
During use, rotating shaft 22 rotarily drive contiguous block 30 around the shaft 22 radial rotary, connector is located at receiving hole 41
In, thus driving actuated element 40 to rotate it is achieved that the moment of torsion between motor 20 and actuated element 40 transmits.
The inner surface of rotating shaft 22 and the connecting hole 311 of contiguous block 30 is spaced default distance finally it should be noted that for biography
For motivation structure 100, this distance is minimum, and the lap fit being applied between countershaft 22 and connecting hole 311 is carried out
Fine setting.This distance can absorb or make up the rotating shaft 22 itself leading to due to fixing motor 20 and contiguous block 30, actuated element
The deviation of 40 axis decentraction.In other words, when there is decentraction deviation in the axis of rotating shaft 22 and contiguous block 30, rotating shaft 22
Axis can with the axis runout of contiguous block 30, actuated element 40, but due between rotating shaft 22 and connecting hole 311 for gap coordinate,
So will not be stuck between rotating shaft 22 and connector, therefore can prevent motor 20 to during actuated element 40 transmitting torque
Produce vibrations and noise, improve the efficiency of motor 20, and this drive mechanism 100 is relatively stable.
Further, since between rotating shaft 22 and contiguous block 30 by the way of the cooperation of gap, without countershaft 22 and contiguous block
Installation direction between 30 and position carry out close adjustment, simplify installation process, and have saved between installation.
It is appreciated that in other embodiments, the connecting hole 311 of contiguous block 30 is alternatively rectangle, five corner apertures or does not advise
The then hole of shape, as long as rotating shaft 22 can drive contiguous block 30 to rotate.
In the present embodiment, the first supporting part 11 and the second supporting part 12 is all vertical with connecting portion 13 is connected.Can manage
Solution, in other embodiments, the first supporting part 11 can be connected with connecting portion 13 at other angles with the second supporting part 12.
It is appreciated that in other embodiments, receiving hole 41 and driving section 32 are alternatively other shapes, as long as driving section
32 can be connected to transmitting torque with receiving hole 41.
It is appreciated that in other embodiments, the driving section 32 of contiguous block 30 can be cancelled, now, in contiguous block 30
Offer receiving hole, actuated element 40 is provided with projection portion, the projection portion of actuated element 40 is arranged in the second through hole 121, and
It is inserted in the receiving hole of contiguous block 30, thus actuated element 40 can be connected with contiguous block 30.
It is appreciated that in other embodiments, contiguous block 30 and actuated element 40 also can include gear and internal tooth respectively
Circle, contiguous block 30 still can be connected to transmitting torque with actuated element 40.
In addition, those skilled in the art also can do other changes in this utility model spirit, certainly, these are according to this reality
The change made of new spirit, all should be included in the claimed scope of this utility model.
