Detailed description of the invention
Below in conjunction with accompanying drawing, further details of narration is carried out to the utility model.
As shown in accompanying drawing 1 and 3, a kind of spring energy-storage tumbler being accurately positioned, it includes firm banking the 1st, ball
Rotary shaft the 2nd, compression spring the 4th, the ball screw nut that screw axis 3 and ball screw axle 3 are wholely set is the 6th, in order to limit described rolling
The rotating limit block of the rotational freedom at left and right directions for the ballscrew nut 6 is the 5th, for carrying out to the stroke of described ball screw nut 6
Spacing locating part, for supporting the fixing end assembly of described rotary shaft 2 one end and for supporting described ball screw axle 3 end
Support end assembly.
In fixing end assembly of the present utility model includes fixing end bearing block the 7th, angular contact bearing the 8th, bearing (ball) cover the 9th, bearing
Packing ring 10 and clamp nut 11, described rotary shaft 2 is assemblied in described angular contact axle by bearing inner washer 10 and clamp nut 11
In holding 8, described angular contact bearing 8 is installed in described fixing end bearing block 7 by described bearing (ball) cover 9, described fixing end axle
Bearing 7 is fixedly installed on described firm banking 1.Fixed bearing block be then be locked into firm banking 1 together with, so, ball wire
The side-to-side movement just of the rotary shaft of bar, seesaws, and moves up and down, front and back rotates, and rotates 5 frees degree up and down just by agretope
, the only rotation of left and right directions.
Support end assembly of the present utility model includes support end bearing block 13 and deep groove ball bearing 12, described ball screw axle
The end of 3 is installed in described support end bearing block 13 by described deep groove ball bearing 12, and described support end bearing block 13 is fixed
It is arranged on described firm banking 1.Support end bearing block 13 and deep groove ball bearing 12 play the support to ball screw shaft end
Effect, it is ensured that the rotation precision of ball screw axle and bearing capacity.
As shown in Figure 2, ball screw nut 6 is assemblied on described ball screw axle 3, and ball screw nut 6 is by lock
Tight screw 17 and rotating limit block 5 are secured together, and rotating limit block to be respectively arranged with the path that two outer rings fit to firm banking 1 up and down deep
Ditch ball bearing 18, the inner ring of deep groove ball bearing 18 is then fixed axle 20 by upper and lower two bearing inner race packing rings 19 and bearing and is fixed to
In the groove of the upper and lower sides of rotating limit block 5.Thus by roll by way of, limit ball wire bar pair in transmission process
The free degree that left and right directions rotates.Thus ensure that it to start and to possess good rigidity and elastic force accurately when stopping.
Compression spring 4 is fixed on firm banking 1 by spring firm banking 14, and above-mentioned spring firm banking 14 is by lock
Jack panel 15 is provided with stop screw 16, and the other end of compression spring is applied directly to ball screw nut rotating limit block output bullet
Power, and limiting screw 16 is jointly to act on ball screw fixed bearing block 7, accurately limits ball screw nut 6 and ball
The stroke of feed screw nut's rotating limit block 5 and initial position.
As shown in Figure 4, the ball screw nut component of ball wire bar pair, is limited to screw mandrel and fixes the initial bit of end
In the agretope B of the stop screw of A and end, if figure is to indicate to obtain nut movable stroke S=L2-L1, and ball wire bar pair
Helical pitch be datum (during design determine) a, then can obtain the revolution that rotary shaft can rotate is n=S/a=(L2-L1)/a.L2
Can be by spring firm banking 14 and the position of stop screw 16 realizes that little scope is adjustable, because the initial bit of end fixed by screw mandrel
It is all rigid structure with the agretope of the stop screw of end, so the precision of its position and repeatability are very high, i.e. also
It is the slewing area of rotary shaft and the precision of initial position is very high and controlled.Power F of compression spring is to be applied directly to
On nut assembly, the torsion T=F*a/ π of equal value of rotation can be calculated again by helical pitch a of ball screw, when nut group
When part is by position left limit, spring force now is that initial pressure F is initial, necessarily can show that initial moment T of rotation is initial=F
Initial * a/ π, equally, this spring can carry out fine tune by the right position of spring firm banking 14, it is also possible to passes through
Change spring and change spring force.
As shown in Figure 5, protection shell 21 can be installed outside this device additional, can play while attractive in appearance in protection
Portion's structure and lubrication, it is ensured that this structure is functions reliably and efficiently.
Principle of the present utility model is as follows:
Ball wire bar pair is used to carry out axial force and location point control, first, the circle of the nut of ball wire bar pair
Circumferential direction limits it by 2 journal bearings and circumferentially rotates, and such nut is only possible to coordinate with ball screw do axial fortune
Dynamic, and on the axially-movable direction of nut, it is provided with compression spring and front and back two catch point altogether, under original state, feed screw nut is subject to
To the pressure of compression spring, nut can be close to the front catch point in mechanism member, and axle also stops defined location accordingly, now outside
Power could must rotate more than being applied to pretension on axle after spring-compressed nut, if axis of rotation, this ball wire bar pair
The nut that structure will be converted into the rotation of axle in ball wire bar pair overcome moving axially of compression spring force, also just by axle
The energy rotating is converted to the elastic potential energy of compression spring, if after forwarding certain limit to, nut can be run into and be arranged on rear
Motion catch point, then axle can turn motionless, it is achieved that to axle rotation number restriction, and when on axle active force disappear or reduce
After, the pressure of compression spring can allow again the screw axis of ball wire bar pair rotate, until nut reaches rear catch point, axle is also
Accurately having returned in situ, this structure has also returned to original state, and then waits the motion of external force next time.
The course of work of the present utility model is as follows:
To be mounted directly to compression spring on the ball screw nut of ball screw, in an initial condition, nut is because being subject to
Pressure and axial restriction are stopped on the rib on limit, and rotary shaft then can need certain beginning torsion to turn because of spring
Dynamic, and when rotary shaft rotates, this can be changed into the motion of compression spring by the structure of this ball screw, passes through ball screw
Subband moves nut assembly compression spring to the left, thus this portion of energy is converted into the elastic potential energy of spring, and ball screw spiral shell
Moving range be also limited in the catch point of both sides, the slewing area of rotary shaft is also limited accurately, ball screw nut
After bumping against stop screw, rotary shaft then cannot rotate.After the external force of axle disappears or significantly weakens, the elastic force potential energy of this part is again
It is converted into the rotation of axle by the structure of ball screw, because of the existence of upper block, it is achieved that the accurate return of rotating shaft, then this is whole
Nested structure returns in situ, wait next work that reverses, repeat according to this.
The above embodiment is only preferred embodiment of the present utility model, and the not feasible enforcement of the utility model
Exhaustive.For persons skilled in the art, on the premise of without departing substantially from the utility model principle and spirit, it is made
Any obvious change going out, all should be contemplated as falling with within claims of the present utility model.
