Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in figure 1, the utility model specific implementation includes multiple touch single needle components, each touch single needle component from
Top to bottm sets gradually touch needle body 1, turnbarrel 2, bearing backing plate 4 and the U-shaped electromagnet 5 of installation.
As shown in figure 1, touching in the suit top sleeve 14 of the top of needle body 1, symmetrical both sides inwall is set in top sleeve 14
Have along vertical axial guide groove 15, touch and be fixedly connected with horizontal pin 6, horizontal pin 6 on the symmetrical both sides outer wall in the top of needle body 1
In embedded guide groove 15 so that touch needle body 1 and be limited along vertical axes to moving up and down；Touch the bottom of needle body 1 and be provided with external screw thread,
The endoporus of turnbarrel 2 is provided with internal thread, and the touch bottom of needle body 1 is sleeved in the top of turnbarrel 2 by self-locking thread 7 forms silk
Thick stick revolute pair, the bottom of turnbarrel 2 are provided with horizontal through hole 13, and the level of magnetic rod 3 is mounted in horizontal through hole 13 with wearing；Rotary sleeve
2 lower end centers of cylinder are connected with short axle 8, and the upper end center of bearing backing plate 4 is provided with centre bore 9, and short axle 8, which is inserted into centre bore 9, to be caused
Turnbarrel 2 and bearing backing plate 4 form revolute pair connection；U-shaped electromagnet 5 is mainly by left electromagnetic pole wall 10 and right electromagnetic pole wall 11
And the middle magnetic patch being connected between left electromagnetic pole wall 10 and the right bottom of electromagnetic pole wall 11 is formed, bearing backing plate 4 is placed on U-shaped
Between the left electromagnetic pole wall 10 and right electromagnetic pole wall 11 of electromagnet 5 and on middle magnetic patch.
Magnetic rod 3 is between left electromagnetic pole wall 10 and right electromagnetic pole wall 11, and the magnetic pole at 3 horizontal both ends of magnetic rod
Opposite polarity, left electromagnetic pole wall 10 are opposite with the pole polarity of right electromagnetic pole wall 11.
Magnetic rod 3 and the interference fits of horizontal through hole 13, the i.e. diameter of magnetic rod 3 are micro- straight more than horizontal through hole 13
Footpath, to ensure that magnetic rod 3 will not shift movement in the horizontal through hole 13 below turnbarrel 2.
Short axle 8 and the gap of centre bore 9 coordinate, i.e. the micro- short axle 8 more than turnbarrel 2 of the internal diameter of centre bore 9 of bearing backing plate 4
Diameter, to ensure that turnbarrel 2 can be in the 4 cofree rotation of bearing backing plate.
The space for winding magnet coil 12 is left between the bottom of bearing backing plate 4 and the middle magnetic patch of U-shaped electromagnet 5,
Magnet coil 12 is wound on the middle magnetic patch of the U-shaped bottom of electromagnet 5.
As shown in figure 4, the screw thread self-locking principle that the utility model touches single needle component is：
When touching needle body threadingly face downslide, axial load FQThe active force of needle body downslide is touched for driving, F is obstruction
Touch the active force that needle body glides, frictional force FfDirection with touch needle body the direction of motion it is opposite.By FR, F and FQThe power of composition
Polygon Closed Graph can obtain：
F=FQ tan(λ-ρ)
Wherein, λ represents lead angle, and ρ represents angle of friction；
Now, when the internal thread of turnbarrel circles, input work W1=FQS, S represent lead, output work W2
=F π d2, then the efficiency of screw pair be：
In formula, d2The pitch diameter of thread is represented, η is the efficiency of screw pair, and λ is the slope of screw pair, and ρ is the friction system of screw pair
Number.As λ≤ρ, i.e. η≤0, illustrate no matter FQPower is much, and touching needle body can not all move, it is possible to achieve touch oneself of needle body
Lock.
Operation principle of the present utility model is as follows：
As shown in Figures 2 and 3, the expression inoperative position on the left side, the expression working position on the right, forward direction is led to when giving electromagnet 5
During electric current, now touch needle body 1 and be in inoperative position.When leading to reverse current to electromagnet 5, turnbarrel 2 is in electromagnetic force
Rotate, moved upwards so that touching needle body 1, in working position under effect.
Touch the process that needle body rises to working position (Fig. 2 and Fig. 3 right side)：By giving magnet coil 12 logical positive electricity
Stream so that the left electromagnetic pole wall 11 of U-shaped electromagnet 5 forms S poles, and right electromagnetic pole wall 10 forms N poles, respectively with the S of magnetic rod 3
Pole and N are extremely attracting, promote turnbarrel 2 to rotate forward, and promote touch needle body 1 to move upwards through self-locking thread 7.After power-off,
Needle body 1 is touched due to the self-locking of self-locking thread 7, will not freely move downward, be maintained at working position.
Touch the process that needle body drops to inoperative position (Fig. 2 and Fig. 3 left side)：By giving magnet coil 12 logical reversely electricity
Stream so that the left electromagnetic pole wall 11 of U-shaped electromagnet 5 forms N poles, and right electromagnetic pole wall 10 forms S poles, respectively with the S of magnetic rod 3
Pole and N poles are repelled each other, and promote turnbarrel 2 to rotate backward, and promote touch needle body 1 to move downward through self-locking thread 7.
As can be seen here, the utility model can realize the projection for touching needle body and self-locking, the tactile available for braille or figure
It has been shown that, there is it to protrude significant technique effect.
