Abstract
The invention discloses a design theory for compressing a raceway body in a rolling guide pair. The guide rail is composed of a guide rail substrate, the raceway body and a raceway compression body. The guide rail substrate and the raceway compression body use certain light metal with enough strength and rigidity comprising aluminum alloy. The raceway body uses bearing steels, spring steels and the like with high strength and hardness. The raceway body is positioned in grooves of two sides of the guide rail substrate or raceway compression body, the raceway compression body and the raceway body are used together by screws for compressing on the guide rail substrate, so that the raceway body forms a set of guide surfaces which accord with slide block trajectory precision and rolling body contact precision.
Description
Technical field
The present invention relates to a kind of precision and move package assembly, be usually used in equipment manufacture, be particularly suitable for IT industry and industrial automation industry with the rolling guide-rail pairs middle guide.
Background technique
Mostly the linear rail by-product that uses in the market is that rolling element is circulating, and what its guide rail used basically is the steel overall structure.Also have at present the guide rail bending is used for curvilinear motion or rotatablely moves.
Because the assembling of inlaying of combined type raceway body does not have a kind of structure of standard, limit self elastic force is held in habitual usually dependence tightly, and to hold the mode fastening force of fixing raceway body tightly little; The holding the mode of holding tightly the fastening force that limit (102) makes it to produce plastic deformation tightly and can strengthen of extruding guide rail matrix (101); As depicted in figs. 1 and 2; But hold tightly that pointed shape must be made in the limit and make strength reduction; Held tightly the restriction of limit plasticity size in addition, continue to strengthen fastening force like need and just can't realize.
It is limited that this type of mode is held power tightly, cause the guide rail of made to exist to be easy to generate loosening, influence shortcoming such as working life.
And the above mode that is pressed into needs the special equipment that is pressed into just passable, and needs the compression tool of plurality of specifications, and this mode is increasing the cost of producing guide rail virtually.
Summary of the invention
The invention provides the design theory that compresses of raceway body in a kind of rolling guide-rail pairs.Use the raceway pressure strip that the raceway body is exerted pressure, make the guide rail matrix produce plastic deformation, form the groove identical together, the raceway body effectively is fixed on the guide rail matrix, form the guide rail in the guiding pairs with the raceway shape.
Advantage of the present invention is:
1. the guide rail matrix being told a part becomes the raceway pressure strip, groove is comparatively appeared and fine finishing easily.
To the raceway body exert pressure to hold limit intensity tightly higher, can apply very big impacting force, the guide assembly of made is solid and reliable.

Embodiment:
In a kind of rolling guide-rail pairs the raceway body compress design theory, the guide rail in the guiding pairs (11) is made up of guide rail matrix (1), raceway body (2) and raceway fastening body (3).Thereby form accordingly with it by slide block and roller rolling, that be installed in the slide block that matches with the outer rim shape of raceway body in the guiding pairs.
With reference to concrete exemplifying embodiment product is described.
The oblique drawing of the practical implementation example of using for this product shown in Figure 3 is the form after partly cutting off from the centre, the mounting hole (B7) of evenly arranging on it, and the length of guide rail can be done very longly.Shown in Figure 4 is the end view of rolling guide-rail pairs exemplifying embodiment.Fig. 5 is the constitutional diagram and the sectional view of guide rail.
To shown in Figure 7, rolling guide-rail pairs is made up of guide rail (11) and slide block (12) like Fig. 3.Its middle guide is made up of guide rail matrix (1), raceway fastening body (3) and raceway body (2).Guide rail matrix (1) and raceway fastening body (3) compress the raceway body groove (B1) that forms length direction.Has the relevant circular arc of external diameter a part of and raceway body (2) in the raceway body groove (B1) at least.
Guide rail matrix (1) and raceway fastening body (3) use certain that comprise aluminum alloy to have the light metal die cast of sufficient intensity and rigidity, are requiring need drawing moulding under the high situation of straightness accuracy.Also can directly use certain standard aluminum section bar according to the different guide rail matrixes of purposes, like Figure 14.
Need compress raceway body (2) in the raceway body groove (B1).Can know that from Fig. 7 and Fig. 9 raceway body (2) part over half at least is pressed in the raceway body groove (B1).Remaining part is exposed outside, forms the walking track of the roller in the rolling wheel guide rails pair.The shape of groove (B1) demonstrates indent, and at the radius of arc of the open part radius less than the raceway body, going up the plane at raceway fastening body (3) has bottom surface (B6) near two side portions, like Fig. 8.The guide rail matrix (1) and the raceway fastening body (3) that in the process that compresses, form raceway body groove (B1) produce plastic deformation: guide rail matrix (1) forms the degree of depth and is the impression (B8) of t, and is shown in figure 10; Raceway fastening body (3) is pressed both sides to be upturned; The bottom surface on last plane (B6) is because of upwarping the complanation; Circular arc less than raceway body (2) radius in the groove (B1) obtains stretching and closely contacts with raceway body (2); Thereby closely cooperate with the outer rim formation of raceway body, like Fig. 9, raceway body (2) can't break away from from raceway body groove (B1) and be free.
Materials such as the higher Bearing Steel of raceway body (2) working strength and hardness, spring steel are processed, and precise finish and heat-treating.
To shown in Figure 7, guide rail matrix (1) is gone up no groove, raceway body (2) side of being placed on it like Fig. 3.Made a groove (B1) during raceway fastening body (3) moulding.Groove shapes is as shown in Figure 6, by length less than the straight section (B9) of raceway body (2) radius, the arc section (B10) suitable and prevent that the arc section (B11) that raceway body (2) comes off from forming with the quadrant arc of raceway body (2).The radius of arc section (B10) and (B11) is identical or smaller with the radius of raceway body (2) here.Guide rail matrix (1) and raceway fastening body (3) have formed groove shapes that can raceway body (2) is tightly fixing thus.
Raceway body (2) is placed in the groove (B1) of guide rail matrix (1) or raceway fastening body (3) both sides; Boss (B4) on the raceway fastening body (3) aligns the groove (B5) on the guide rail matrix (1); The purpose of this structure is that the load on the guide rail changes the relative position that also can not have influence on guide rail matrix (1) or raceway fastening body (3), like Fig. 7.
Screw (4) is passed step hole (B3) be screwed in the tapped hole (B2), be pressed on raceway fastening body (3) and raceway body (2) together on the guide rail matrix (1), form a kind of combined type rolling guide.When screw was fastening, different because of guide rail matrix (1) and raceway body material and hardness produced plastic deformation at the guide rail matrix (1) of the part of contact, thereby form a little groove (B8), like Figure 10.
Since groove (B1) both sides of mentioning among the present invention to compress limit thickness unrestricted, thereby intensity is higher, can apply very big impacting force, the guide assembly of made is solid and reliable.
In addition; Raceway body (2) is not pushed by unsettled external force all the time when mounted among the present invention; Can not produce axis deformation; Therefore, as long as the straight line precision of guide rail matrix (1), raceway fastening body (3) and their groove (B1) is up to standard, its raceway straightness accuracy of the guide rail that then assembles can be guaranteed.
Remove Fig. 3 to mode shown in Figure 7 outside, the present invention also is suitable for half guide rail of four raceway single rails shown in Figure 12 and paired use shown in Figure 13.
The guide rail that uses the present invention to make should have precision and soundness without any need for what mounting equipment can guarantee guide rail, is the excellent production method of bimetal guide rail.
