Embodiment
Fig. 1 to Fig. 3 shows a concrete application example of this main shaft self-locking mechanism of the application in drill kind tool, with biography
System drill kind tool (such as Publication No. US6702090 United States Patent (USP)s) identical is that the instrument also includes tool outer casing (in figure not
Draw), the motor for being provided with power is set in tool outer casing, and the motor shaft of the motor is connected by central gear with planetary gear
One planetary plate 1, planetary plate 1 are rotatably provided in tool outer casing, and stopper ring 2 is relatively fixed with tool outer casing, and stopper ring 2 with
Planetary plate 1 is coaxially arranged, and closing piece 3 is provided with stopper ring 2, the coaxially connected output shaft 5 of closing piece 3.Specifically, output shaft 5
Cross section be non-circular shape, the middle part of closing piece 3 offers and output shaft section shape and size identical non-circular hole, output shaft
5 are located in the non-circular hole at the middle part of closing piece 3, so that the two is relatively fixed in circumferencial direction.Also, in planetary plate 1
Portion also offers a non-circular hole bigger than the sectional dimension of output shaft 5, and output shaft 5 is penetrated in the non-circular hole of the planetary plate 1.Before
State and six self-lock pins 4 are provided between closing piece 3, stopper ring 2 and planetary plate 1.Self-lock pin 4, closing piece 3, stopper ring 2, planetary plate 1 four
Between person and non-fully immovable fitting, but can relatively move within the specific limits.
The key improvements of the present embodiment are：A buffering spring sheet 6, the buffering spring sheet are fixedly connected with the closing piece 3
Between closing piece 3 and the axial direction of planetary plate 1, i.e., buffering spring sheet 6 is arranged in closing piece 3 close to that side of planetary plate 1.Also, OK
Astrolabe 1 is towards being fixedly installed the uniform public boss 1a of three circumferences, the buffering spring sheet on the end face of that side of buffering spring sheet 6
6 towards being fixedly installed three female boss 6a being engaged with the male boss 1a on the end face of that side of planetary plate 1.
It is using planetary plate as reference unless otherwise instructed in the application described " axial direction ".
Shown in reference picture 2, during normal work, motor operation and by central gear and planetary gear drive planetary plate 1 around
Own axis, three axially extending projections (not marked in figure) on planetary plate 1 promote wherein three self-lock pins 4 respectively
It is mobile counterclockwise, the planomural face for making the non-circular hole hole wall in the middle part of it be resisted against output shaft 5 when planetary plate 1 rotates a certain angle
After on (such as Fig. 1), directly output shaft 5 will be driven to rotate by planetary plate 1, latch segment 3 follows output shaft 5 together to rotate.This
When, planetary plate 1 and the geo-stationary of latch segment 3, six self-lock pins 4 are in the wide space between closing piece 3 and stopper ring 2,
Closing piece 3 and stopper ring 2 will not be locked, so closing piece 3 can be constantly in rotary state under the drive of output shaft 5.
Shown in reference picture 3, during the tool spindle self-locking is had an effect, due to motor side (i.e. planetary plate side)
It is very fast that electric brake make it that the rotating speed of planetary plate 1 declines, and the rotary inertia of the side of output shaft 5 (i.e. closing piece side) is larger, so row
The trend (because output shaft 5 can drive the synchronous axial system of closing piece 3) relatively rotated between astrolabe 1 and closing piece 3 be present, now planetary plate 1
It is larger with the speed discrepancy of closing piece 3.And in the present embodiment, due to female boss 6a on the male boss 1a on planetary plate 1 and buffering spring sheet 6
Presence, both can be hindered to relatively rotate, reduce both speed discrepancies.It is public convex when planetary plate 1 and closing piece 3 relatively rotate
Platform 1a and female boss 6a are mutually contradicted, so that male boss 1a applies the axial thrust towards closing piece direction to female boss 6a,
In the presence of the axial thrust, buffering spring sheet 6 produces the axial deformation to the direction of closing piece 3.Female boss 6a gets over male boss 1a,
Mutually hindered by male and female boss, reduce the rotating speed of the relative rotation speed of planetary plate 1 and closing piece 3, i.e. the relative brake circle 2 of closing piece 3
Also effectively reduced.And the noise source for producing brake noise " click click " sound is closing piece 3, self-lock pin 4, stopper ring 3 three zero
The strike note of part, so brake noise can effectively be reduced by reducing the speed discrepancy of above-mentioned three part, it can be seen by above-mentioned reasoning
Go out the effect by male boss 1a and female boss 6a, hence it is evident that reduce closing piece, self-lock pin, the relative of three parts of stopper ring turn
Speed.After female boss 6a of closing piece crosses the male boss 1a on planetary plate, closing piece 3 (in the case where the inertia of output shaft drives) opposing rows
The rotational angle of astrolabe 1 is θ °, the rotation of closing piece 3 can stir corresponding three self-locking footwear 4 be moved to closing piece 3 and stopper ring 2 it
Between small space in so that these three self-lock pins 4 are stuck between stopper ring 2 and closing piece 3, closing piece 3 and stopper ring 4
Geo-stationary, output shaft 5 stop operating, and main shaft (i.e. output shaft 5) self-locking action occurs.
Above-mentioned operation principle can also refer to Publication No. US6702090 United States Patent (USP)s.
In order to ensure in above-mentioned auto-lock process, female boss 6a can be smoothly across male boss 1a, the public affairs in the present embodiment
Formed on boss 1a and female boss 6a match coordinate inclined-plane, the inclined-plane can be flat incline plane or curve slope or
Spheric inclined-plane.
Under normality, buffering spring sheet 6 is spaced apart in the axial direction with closing piece 3, so as to ensure to send out in main shaft self-locking
During raw effect, buffering spring sheet 6 has corresponding axial deformation space.
Above-mentioned buffering spring sheet 6 is usually steel disc.
In the present embodiment, public boss 1a is integrally formed on planetary plate 1, i.e., the two is structure as a whole, and certainly, we also may be used
So that public boss 1a and planetary plate 1 are arranged into Split connection structure, such as：Public boss 1a is arranged to consolidate with the screw thread of planetary plate 1
Fixed screw.
In the present embodiment, female boss 6a is integrally formed on buffering spring sheet 6, i.e., the two is structure as a whole.And female boss
What 6a was stamped and formed out on buffering spring sheet 6.
It should be noted that above-mentioned male boss 1a and female boss 6a quantity is not limited to three, can also be arranged to
One, two or four etc..But, in order to ensure reducing effect of the male and female boss to brake noise, it is generally advisable to set
More than two male boss 1a and female boss 6a.
Certainly, above-described embodiment is only the technical concepts and features for illustrating the application, and its object is to make people much of that
Solution present context is simultaneously implemented according to this, and the protection domain of the application can not be limited with this.It is all according to the application major technique
The equivalent transformation or modification that the Spirit Essence of scheme is done, should all cover within the protection domain of the application.
