Abstract
The utility model discloses a kind of singe screw and drive classification multistage mobile mechanism, comprise screw rod, travelling nut, screw rod mounting sheet, fixed base, the travelling nut described screw rod being provided with at least two sections of screw threads and mating with screw thread, be optical axis between described two sections of screw threads, described optical axis length is slightly less than two the travelling nut width sums in left and right.The utility model collection achieves the effect realizing the movement of classification multistage by single bolt rod driving.
Description
Technical field
The utility model relates to a kind of screw drive mechanism, is specifically related to a kind of singe screw and drives classification multistage mobile mechanism.
Background technique
At present, traditional screw drive just can realize little torque and promote high-torque, completes the function that the change of driving direction and rotary motion become straight line motion simultaneously.This drive form can only the movement of a bolt rod driving object.When needs control multiple moving article, just need multiple screw rod and come.Particularly for multiple moving article and when having sequential between them, namely an object can move next object after having moved, and at this moment just needs multiple driving source, defines certain waste.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of singe screw and drives classification multistage mobile mechanism, achieves the effect realizing the movement of classification multistage by single bolt rod driving.
The technological scheme that the utility model technical solution problem adopts is: a kind of singe screw drives classification multistage mobile mechanism, comprise screw rod, travelling nut, screw rod mounting sheet, fixed base, it is characterized in that: the travelling nut being provided with at least two sections of screw threads and mating with screw thread on described screw rod, be optical axis between described two sections of screw threads, described optical axis length is slightly less than two the travelling nut width sums in left and right.
As further improvement, be provided with locating slot bottom described each travelling nut, described fixed base is provided with and mates and elasticity locking ball with locating slot set bottom travelling nut.
The utility model can move the helical quantity of corresponding screw thread on screw rod by arranging each nut, realize different nut under identical screw speed, different travelling speeds; By changing the length of every section of screw thread, the difference of the nut displacement distance in respective threaded section can also be realized.When screw rod turn contrary time, the movement direction of nut is contrary.At this moment remain successively one by one nut move.If when the helical rotation direction on the screw rod of each nut and cooperation is different, the driving direction that on same screw rod, different nut is different can also be realized.
The beneficial effects of the utility model are: the travelling nut being provided with at least two sections of screw threads and mating with screw thread on described screw rod, realize the effect realizing the movement of classification multistage by single bolt rod driving.
Accompanying drawing explanation
Fig. 1 is the Organizational Structure schematic diagram of the utility model embodiment.
Below in conjunction with accompanying drawing, the utility model is described further.
Embodiment
As shown in Figure 1, a kind of singe screw drives classification multistage mobile mechanism, comprise screw rod 1, travelling nut, screw rod mounting sheet 4, fixed base 5, the travelling nut (2 described screw rod 1 being provided with two sections of screw threads and mating with screw thread, 3), be optical axis 10 between described two sections of screw threads, optical axis 10 length is slightly less than travelling nut (2,3) width sum.Be respectively equipped with locating slot (6,7) in travelling nut (2,3) bottom, described fixed base (5) is provided with and mates and elasticity locking ball (8,9) with locating slot (6,7) set by (2,3) portion at the bottom of travelling nut.
During use, rotating screw bolt 1, nut 2 drives, and nut 3, under the effect of locating slot and elastic steel ball, is parked in optical axis 10, not mobile.When nut 2 shifts out screw thread, nut 2 pushes up nut 3, optical axis 10 length between the screw thread of two ends is set to be less than two nuts (2,3) width sum, and the elastic force that positioning device produces is less than the elastic force of end face spring sheet, therefore now nut 3 enters screw flight interval under the promotion of nut 2, realizes by the driving of same screw rod to nut (2,3).Now nut 2 is positioned in corresponding position and no longer moves under the effect of locating slot and elastic steel ball.Nut on screw rod 1 optical axis 10, because of not by thrust, rests on original position under the effect of each self locating device.
From the above mentioned, when be provided with three sections of screw threads and mate with screw thread travelling nut time, by that analogy, when second nut moves to next section, make the 3rd nut work successively.
Claims (2)
1. a singe screw drives classification multistage mobile mechanism, comprise screw rod (1), travelling nut, screw rod mounting sheet (4), fixed base (5), it is characterized in that: the travelling nut being provided with at least two sections of screw threads and mating with screw thread on described screw rod (1), be optical axis (10) between described two sections of screw threads, described optical axis (10) length is slightly less than two the travelling nut width sums in left and right.
2. a kind of singe screw as claimed in claim 1 drives classification multistage mobile mechanism, it is characterized in that: be provided with locating slot bottom described each travelling nut, described fixed base (5) is provided with and mates and elasticity locking ball with locating slot set bottom travelling nut.
