Detailed description of the invention
Deferring to technique scheme, as shown in Figure 1 to Figure 3, a kind of feed screw nut demonstrates mechanism, including base plate 1, base plate 1
On be vertically installed with a pair gripper shoe 2, be arranged in parallel between two gripper shoes 2；Optical axis the 3rd, leading screw 4 are installed between gripper shoe 2
And gear shaft 17, wherein optical axis 3 is positioned above leading screw 4, and gear shaft 17 is positioned at below leading screw 4, and optical axis 3 and gear shaft 17 can weeks
To rotation, leading screw 4 can circumferentially rotate, it is possible to moves axially；Optical axis 3 is set with fastener 9, for fixing the position of nut 8；
Being set with the nut 8 coordinating with fastener 9 on leading screw 4, nut 8 contacts with gear shaft 17, can drive nut 8 when gear shaft 17 rotates
Rotate；Gear shaft 17 is driven by a gear 18.
As it can be seen, the axial cross section of fastener 9 is I-shaped, it axially offers circular hole to be enclosed within optical axis 3, nut
The edge of 8 is sleeved on the middle part of fastener 9；Fastener 9 offers the first screwed hole 11 running through fastener 9 and optical axis 3, the first spiral shell
Being equipped with the first fastening bolt 10 on pit 11, after the first fastening bolt 10 is screwed in the first screwed hole 11, its end can connect with optical axis 3
Touch, thus fastener 9 can be fixed relative to optical axis 3, also just define moving axially of nut 8.
The two ends of leading screw 4 are provided with the extension passing gripper shoe 2, and the two ends that extension can be regarded as leading screw 4 are divided
Do not axially elongate the structure of formation, offer multiple rectangular channel 5, another extension vertically on an extension wherein
On the multiple cannelure 7 that around extension arrange is distributed in the axial direction, for demonstrating different fit forms.
All trip bolt 13 is provided with boss 12 on gripper shoe 2 sidewall above extension, on two boss 12 all
Offer the second screwed hole 16, and be respectively fitted with the second fastening bolt 14 and the 3rd fastening bolt 15；Wherein second fastening bolt 14
End can extend in described rectangular channel 5, thus limits the rotation of leading screw 4；The end of the 3rd fastening bolt 15 can extend into institute
In the cannelure 7 stated, thus limit leading screw 4 movement in the axial direction.The end of the extension being provided with rectangular channel 5 is provided with
One handwheel 6, can make leading screw 4 rotate by the first handwheel 6；Gear 18 is installed by the short axle 19 through gripper shoe 2, at short axle
The end of 19 is provided with the second handwheel 20, gear 18 can be made to rotate by the second handwheel 20.
Several demo modes of this device are as follows:
1. nut 8 is motionless, and leading screw 4 rotates and completes to move axially
Screwing in the first fastening bolt 10, to limit moving axially of nut 8, then rotating the first handwheel 6 provides power to make
Leading screw 4 rotates, and under the interaction force of nut 8, leading screw 4 also axially moves simultaneously.
2. nut 8 circular motion, leading screw 4 moves axially
First fastening bolt 10 is screwed in, to limit moving axially of nut 8, the second fastening bolt 14 is screwed into rectangular channel 5
In, limiting leading screw 4 and rotate, rotate the second handwheel 20, rotated by gear 18 driven gear axle 17, gear shaft 17 rotates and drives spiral shell
Female 8 rotate, and leading screw 4 moves axially under the interaction force of nut 8.
3. leading screw 4 maintains static, and nut 8 rotates and moves axially
It is screwed into the second fastening bolt the 14th, the 3rd fastening bolt 15 in rectangular channel the 5th, cannelure 7 respectively, limit leading screw 4 simultaneously
Axial, circumferential movement, rotate the second handwheel 20 to drive nut 8 to rotate, now nut 8 is under the interaction force of leading screw 4
Move axially.
4. leading screw 4 rotates, and nut 8 moves axially
Screw in the 3rd fastening bolt 15, limit leading screw 4 axially on motion, now leading screw 4 still can rotate.Simultaneously first
Fastening bolt 10 screws out, and makes nut 8 to move axially, and shakes the first handwheel 6, can realize this process.
