Background technique
At present, drive the guide rail of two silk braids motion with screw mandrel, silk braid can only be walked the distance of rail length half, because the left-right rotary screw thread on screw mandrel divides be located at screw mandrel two ends, respectively account for half, and silk braid is Full Thread FT, meeting is to interfere.
Model utility content
The utility model mainly solves the technical problem existing for prior art; Provide a kind of ram travel longer, compact structure, good rigidly, the omnidistance guide rail of a kind of bi-directional synchronization of optional speed ratio.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The omnidistance guide rail of a kind of bi-directional synchronization, it is characterized in that, comprise a rhizoid bar and two slide blocks, is slide block one and slide block two respectively; Described screw mandrel outer wall is staggeredly equipped with left-handed thread and right-handed thread; Slide block one and slide block two are respectively equipped with curve bath, and the curve bath inwall of slide block one is provided with the screw thread with left hand thread engagement, and the curve bath inwall of slide block two is provided with the screw thread coordinated with right-handed thread; Two ends are optical axises, and optical axis is provided with the stand that freely can rotate on optical axis; Described screw mandrel is provided with at least two directed guide rails, and slide block one and slide block two can do relatively reciprocating motion along two directed guide rails respectively.
At the omnidistance guide rail of above-mentioned a kind of bi-directional synchronization, described directed guide rail is two, is upper and lower two pieces, and two stands are fixed together with directed guide rail two ends respectively, and each directed guide rail cross section is concave shape, and slide block one upper and lower end face is respectively provided with a projection; The upper and lower end face of slide block two is respectively provided with a projection, in the groove that the projection of slide block one and slide block two is stuck in two directed guide rails and can along directed slide.
Alternatively, at the omnidistance guide rail of above-mentioned a kind of bi-directional synchronization, described directed guide rail is even number root parallel axes parallel to each other, be arranged between two stands, the two ends of axle are separately fixed on two stands, two slide blocks are all provided with hole, the axis in hole and the axis being parallel of parallel axes; The hole of two slide blocks is enclosed within different parallel axes respectively.
In the utility model, the ratio of dextrorotation during screw mandrel and left-handed pitch is exactly the ratio of the movement velocity of two slide blocks
Therefore, the utility model tool has the following advantages: 1. reasonable in design, and structure is simply and completely practical; 2. ram travel is longer, compact structure, good rigidly, optional speed ratio.

Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1
With reference to shown in Fig. 1, the utility model comprises a rhizoid bar and two slide blocks, left-handed and the right-handed thread mixed is provided with in the middle of screw mandrel, two ends are optical axises, optical axis is provided with stand, and stand freely can rotate on optical axis, and two stands are fixed together with W shape guide rail two ends respectively, W shape guide rail has two, is arranged symmetrically with relative to screw mandrel.Two slide blocks are stuck between two U-shaped guide rails, are arranged symmetrically with relative to screw mandrel.W shape guide rail is provided with two grooves, slide block is provided with two projections, can slide in the groove being stuck in two W shape guide rails, the face 33 on slide block and the face 22 on guide rail fit, and above the identical faces on another guide rail and slide block, the symmetry plane of 33 fits (not indicating in figure).One of them slide block is provided with dextrorotation partial thread, and another slide block is provided with left-handed partial thread, and dextrorotation partial thread has the right-handed thread on screw mandrel to coordinate, the left hand thread engagement on left-handed partial thread and screw mandrel.During work, screw mandrel rotates, and drive two slide blocks to do straight line motion in opposite directions, W shape guide rail is responsible for slider guide; Because two slide blocks are all partial threads, so they meet and do not interfere, variously whole process can be covered.Dextrorotation during production screw mandrel and the ratio of left-handed pitch are exactly the ratio of the movement velocity of two slide blocks.
Embodiment 2
With reference to shown in Fig. 1, screw structure is identical with the screw mandrel in embodiment 1; Two ends optical axis is provided with stand, and stand freely can rotate on optical axis, is fixed with even number root axle parallel to each other between two stands; Two slide blocks, one of them is provided with dextrorotation partial thread, and another is provided with left-handed partial thread, and two slide blocks are all provided with hole, and hole is parallel with the axis of thread; The hole of two slide blocks is enclosed within different parallel axes respectively, and dextrorotation partial thread coordinates with the right-handed thread on screw mandrel, the left hand thread engagement on left-handed partial thread and screw mandrel.During work, screw mandrel rotates, and drive two slide blocks to do straight line motion in opposite directions, parallel axes is responsible for slider guide; Because two slide blocks are all partial threads, so they meet and do not interfere, variously whole process can be covered.Dextrorotation during production screw mandrel and the ratio of left-handed pitch are exactly the ratio of the movement velocity of two slide blocks.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
