Abstract

The utility model provides a telescopic guide pillar. The telescopic guide pillar comprises a first guide wheel frame, an outer guide pillar and an inner guide pillar, wherein the guide wheel frame is arranged on the outer guide pillar in a sleeved mode, the outer guide pillar is arranged on the inner guide pillar in a sleeved mode, a plurality of first idler wheels are respectively arranged on the inner wall of the front side and the inner wall of the rear side of the guide wheel frame, first slide grooves matched with the first idler wheels are respectively formed in the outer wall of the front side and the outer wall of the rear side of the outer guide pillar, the outer guide pillar is connected with the guide wheel frame in a sliding fit mode through two first slide grooves and each first idler wheel, a plurality of second idler wheels are respectively arranged on the left lateral wall and the right lateral wall of the outer guide pillar, second slide grooves matched with the second idler wheels are respectively formed in the outer wall of the left side and the outer wall of the right side of the inner guide pillar, and the inner guide pillar is connected with the outer guide pillar in a sliding fit mode through two second slide grooves and each second idler wheel. The telescopic guide pillar has the advantages of being simple in structure, saving space, and being high in guide stiffness and stability.

Description

A kind of flexible guidepost

[technical field]

The utility model relates to a kind of setting machine apparatus field, refers in particular to a kind of flexible guidepost.

[background technology]

Setting machine is in when work, always guarantees the vertical lift of chuck device by guidepost, to prevent sideslip; Existing guidepost mostly adopts single structure, needs the demand of higher factory building space when satisfying the upper and lower motion of guidepost in the use, footprint not only, and single structure directing rigidity is not high, causes resistance to overturning not good.

[summary of the invention]

The technical problems to be solved in the utility model is to provide a kind of flexible guidepost, and saving space and guiding rigidity are better.

The utility model is achieved in that a kind of flexible guidepost, and this flexible guidepost comprises a wheel frame, an outer guiding post and an inner guiding post; Described wheel frame is sheathed on the described outer guiding post, and this external guide pole sleeve is located on the described inner guiding post; The inwall of the forward and backward both sides of described wheel frame is equipped with a plurality of first rollers; The outer wall of the forward and backward both sides of described outer guiding post is equipped with first chute that matches with every described first roller, and described outer guiding post is joined with described wheel frame cunning and is connected by two described first chutes, every described first roller; The and arranged on left and right sides wall of described outer guiding post is equipped with a plurality of second rollers; The outer wall of the and arranged on left and right sides of described inner guiding post is equipped with second chute that matches with every described second roller, and described inner guiding post is joined with described outer guiding post cunning and is connected by two described second chutes, every described second roller.

Preferable, described outer guiding post, inner guiding post are rhs-structure.

Advantage of the present utility model is: by the mutual socket of wheel frame, outer guiding post and inner guiding post, and by first roller, second roller wheel frame, outer guiding post and inner guiding post can upper and lowerly be stretched, it is better more to save space and stability and rigidity in the use.

[description of drawings]

In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.

Fig. 1 is the front view of a kind of flexible guidepost of the utility model.

Fig. 2 is the lateral plan of a kind of flexible guidepost of the utility model.

[specific embodiment]

See also illustrated in figures 1 and 2, a kind of flexible guidepost 100, this flexible guidepost 100 comprises a wheel frame 1, an outer guiding post 2 and an inner guiding post 3; Described wheel frame 1 is sheathed on the described outer guiding post 2, and this outer guiding post 2 is sheathed on the described inner guiding post 3; The inwall of the forward and backward both sides of described wheel frame 1 is equipped with a plurality of first rollers 11; The outer wall of the forward and backward both sides of described outer guiding post 2 is equipped with first chute 21 that matches with every described first roller 11, and described outer guiding post 2 is connected with described 1 sliding joining of wheel frame by two described first chutes 21, every described first roller 11; The and arranged on left and right sides wall of described outer guiding post 2 is equipped with a plurality of second rollers 22; The outer wall of the and arranged on left and right sides of described inner guiding post 3 is equipped with second chute 31 that matches with every described second roller 22, and described inner guiding post 3 is connected with described 2 sliding joining of outer guiding post by two described second chutes 31, every described second roller 22.The wheel frame 1 of socket successively from outside to inside, outer guiding post 2 and an inner guiding post 3 play a part flexible by first roller 11, second roller 22, when chuck device 4 moves up and down, can guarantee the perpendicular movement non-migration by flexible guidepost 100, not only reduce the demand in factory building height space, and more single guidepost is good on the structural rigidity.

See also illustrated in figures 1 and 2ly again, described outer guiding post 2, inner guiding post 3 are rhs-structure.The purpose of this design is in the rigidity of strengthening outer guiding post 2, inner guiding post 3, and simple in structure being easy to made.

The utility model is when using, by wheel frame, outer guiding post and the socket successively of inner guiding post three ecto-entad, and wheel frame, outer guiding post between the two by first pulley, the first chute sliding block joint, outer guiding post, inner guiding post between the two by second pulley, the second chute sliding block joint; When the chuck device that is connected the inner guiding post lower end is upper and lower vertical when mobile by actuating device, guarantee the vertical mobile accuracy rate of this chuck device by a kind of flexible guidepost of the utility model; Because the demand that telescopic structure is reduced the factory building spatial altitude greatly, and the structural rigidity of wheel frame, outer guiding post and the mutual socket of inner guiding post three is also better than the structural rigidity of existing single guidepost, and more stable when upper and lower perpendicular movement.

Though more than described the specific embodiment of the present utility model; but being familiar with those skilled in the art is to be understood that; our described specific embodiment is illustrative; rather than for the restriction to scope of the present utility model; those of ordinary skill in the art are in modification and the variation of the equivalence of doing according to spirit of the present utility model, all should be encompassed in the scope that claim of the present utility model protects.
