Abstract
The utility model discloses a linear guide slider extrinsic cycle ware needs the technical problem who solves to be, the slide design in the extrinsic cycle ware of current linear guide slider is unreasonable, and the roll effect is poor. A linear guide slider extrinsic cycle ware uses with the ball is supporting includes the slide, the slide is the even number strip, and the axis that uses the guide rail on the extrinsic cycle ware is the axial symmetry setting. The beneficial effects of the utility model are that: reasonable in design, roll effectual.
Description
Technical field
The utility model belongs to industrial automation equipment field, and specifically a kind of application is followed in outer on straight-line guide rail slide block
Ring device.
Background technology
In industrial automation, widely use line slideway auxiliary.General line slideway auxiliary includes line slideway, slide block
Controlled slip on guide rail, drives workpiece or the movement of tool being arranged on slide block.In order to dust-proof, in the glide direction of slide block
Two ends it will usually respectively arrange a dustproof sheet.Chinese patent literature CN104006081A, discloses in August in 2014 on the 27th
" a kind of high anti-dust performance structure of line slideway auxiliary ", it includes guide rail, is arranged on guide rail and can slide on guide rail
Slide block, the rolling element being arranged between guide rail and slide block and roller holder；It is characterized in that：Before this slide block movement direction
Both sides are mounted on end face double kiss lip scrap scraping plate that elastic abrasion-proof material is made afterwards, and this end face double kiss lip scrap scraping plate has correspondence
Double kiss lips in guide rail profile scrape bits hole, and the aperture that this pair of kiss lip scrapes bits hole is double kiss lips, and double kiss lips are outside oblique of the tip of the tongue
Tongue structure.In such scheme, rolling element generally adopts ball, roller holder is provided with slideway, so that ball is in slideway
Interior rolling.In existing scheme, much bigger than the diameter of ball of the diameter of slideway, when leading to ball to roll in slideway, easily go out
Existing lateral deviation, leads to the slip imbalance of slide block, and stability is poor, easily shakes, the abrasion of slide rail and ball is than more serious.
Content of the invention
The utility model technical issues that need to address are, the ramp design in the outer circulation device of existing straight-line guide rail slide block
Unreasonable, rolling effect is poor, thus providing a kind of reasonable in design, straight-line guide rail slide block outer circulation device that rolling effect is good.
To achieve these goals, the utility model adopts the following technical scheme that：A kind of straight-line guide rail slide block outer circulation device,
Support the use with ball, including slideway, described slideway is even number bar, and on outer circulator, the axis with guide rail sets for axial symmetry
Put.
Ball is used to be formed rolling effect between slide block and guide rail, and the slideway arranging in outer circulation device, it is to supply
Ball returns back to rear side by the front side of the glide direction of slide block.Therefore, when ball is in the slideway in outer circulation device, front
Ball only by rear ball promote and in slideway roll.The diameter of slideway is naturally larger than the diameter of ball, therefore in fortune
When dynamic, ball necessarily occurs in slideway and rocks, this rock can lead to slide block slip uneven, stability is poor, easily
Shake, the abrasion of slide rail and ball also can be than more serious.The quantity of slideway is set to even number bar by this programme, on outer circulator
Arranged with the axis of guide rail for axial symmetry.Such design, on the one hand be drastically reduce the area in unilateral slideway by equalising torque
The amplitude that ball rocks, optimizes the counterbalance effect of slide block, on the other hand alleviates the stress in unilateral slideway, decreases ball
With way rub, extend the service life of ball and guide rail.
Preferably, the cross sectional shape of described slideway is formed by connecting by symmetrical twice circular arc A and B；Radius with circular arc A
For a, with the radius of circular arc B as b, with the radius of ball as r, there is a=b, and a ＞ r.This programme by traditional the cross section of slideway shape by
Single circular arc is improved to symmetrical two circular arc, and the radius of circle that circular arc is located is more than the radius of ball.Such design so that
Ball is sandwiched between two circular arcs to a certain extent, and ball is improved to by original bottom one point with the contact point of slideway
Each point on the two side of bottom.Contact point increases to 2, you can thoroughly eliminate the swing when rolling for the ball.
Preferably, described a ＞ r ＞ 0.9a.The radius of ball is arranged on one times of arc radius and 0.9 times of arc radius
Between, so that ball is mated with the size of circular arc more reasonable, degree of stability is higher.
Preferably, described slideway is 4, set up separately in upper left, the upper right, bottom left of outer circulator, lower right.Overall balance
Stablize and cost is it is proposed that 4 slideways of setting, mate 4 groups of balls, build 4 scrolling bands between slide block and guide rail, it is possible to obtain ratio
Comparatively ideal slide block sliding effect.
In sum, the beneficial effects of the utility model are：Reasonable in design, rolling effect is good.
Brief description
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the front view of Fig. 1,
Fig. 3 is the schematic diagram of slideway and ball matching relationship.
Wherein：5 balls, 34 slideways.
Specific embodiment
With specific embodiment, the utility model is further described below in conjunction with the accompanying drawings.
Embodiment as shown in Figure 1 and Figure 2, is a kind of straight-line guide rail slide block outer circulation device, follows outside such straight-line guide rail slide block
Ring device is arranged in pairs at the slider body two ends of straight-line guide rail slide block, forms rolling with ball 5 and connect between slider body and guide rail
Touch, ball enters the slideway 34 of outer circulation device in the front end in slide block movement direction, then the promotion by rear ball, after returning back to
End, and so on circulates.In this example, the quantity of slideway is 4, sets up separately in upper left, the upper right, bottom left of outer circulator, lower right,
Mate 4 groups of balls, build 4 rolling relations between slide block and guide rail, form stable slide block sliding effect.
As shown in figure 3, the shape of cross section of slideway is formed by connecting by symmetrical twice circular arc A and B；Radius with circular arc A
For a, with the radius of circular arc B as b, with the radius of ball as r, there is a=b, and a ＞ r ＞ 0.9a.Ball slides in slideway, simultaneously
Touch a point on circular arc A and circular arc B, limit the unordered of ball and rock, eliminate the destabilizing factor of slide block.
A kind of straight-line guide rail slide block outer circulation device of this example, the roll stabilization of ball, 4 slideways ensure that the slip of slide block
Balance, makes the sliding effect of whole slide block reach gratifying degree.
