Each guiding fixing bar has at least two transversal bolt holes. Screws are inserted into the bolt holes from the exterior to the housing and supported against the inner wall of the guiding slots. The utility model effectively ensures the linearity of grating ruler after connection.
Description
Technical field
The utility model relates to extension grating ruler, especially the docking mechanism of extension grating ruler.
Background technology
The grating chi is widely used in various precision finishing machines.The low reasons such as transporting difficulty that reaches of fabrication yield owing to long Grating glass causes the cost of big-and-middle-sized precision finishing machine high.In order to address this problem, people are by the whole bag of tricks extension grating ruler, to satisfy the demand of big-and-middle-sized lathe.But, can guarantee its linearity after adjacent two sections grating chis butt joint, will have influence on the measuring accuracy of grating chi; Because temperature variation causes the flexible of each section grating chi, and the problems such as sealing of seam crossing, all can have influence on the measuring accuracy of grating chi.
The utility model content
Primary and foremost purpose of the present utility model provides a kind of docking mechanism of extension grating ruler, can guarantee to dock the linearity of back grating chi to greatest extent.
Further purpose of the present utility model is to make docking mechanism can solve the sealing problem of seam crossing effectively.
For reaching primary and foremost purpose, the utility model adopts following technical scheme: the docking mechanism of extension grating ruler, be linked to be a straight line by multistage grating chi chi shell head and the tail butt joint successively, and two gathering sills are longitudinally arranged in every section chi shell; Connect by two guide securement bars that are limited in each gathering sill respectively and can move in the vertical between adjacent two sections chi shells, every guide securement bar has at least two horizontal screws, and corresponding screw stretches into outside the chi shell that to pass each screw respectively inconsistent with the inwall of this two chis shell gathering sill respectively.
As a kind of preferred version, the xsect of the gathering sill in the described chi shell is " protruding " font of mouthful narrow inner width, and the xsect of described guide securement bar is down " T " font, and guide securement sliver transvers section the widest part is greater than the gathering sill xsect width at narrow place; Described each screw crosses the guide securement bar from the gathering sill notch.
As improvement, described two longitudinally the notch of gathering sill lay respectively at orthogonal two sides on the chi shell.Every guide securement bar has four screws, two gathering sills that are in one section chi shell, and two other is in the gathering sill of another chi shell.
As further improvement; pass the screw on the described guide securement bar and made by all-metal with two screws that the inwall of one ruler shell gathering sill wherein offsets, the thin end of two other screw that offsets with the inwall of other one ruler shell gathering sill studs with plastic pellet or rubber grain.
In order to solve the sealing problem of seam crossing under the situation that existence is expanded with heat and contract with cold, be equipped with between described wantonly two sections adjacent chi shells one with the identical rubber sheet gasket of chi shell shape of cross section.For rubber sheet gasket can accurately be firmly fixed, on the relative both ends of the surface a plurality of shrinkage pools are arranged between adjacent two chi shells, there is corresponding a plurality of protruding grain the both sides of rubber sheet gasket, and each protruding grain embeds in corresponding shrinkage pool.
The length of described arbitrary section chi shell is advisable with 0.80～1.50 meter, and the thickness of rubber sheet gasket is advisable with 1～3mm.
The docking mechanism of the utility model extension grating ruler, it is fixing to achieve a butt joint by two guide securement bars between adjacent two sections chi shells, can guarantee to dock the linearity of back grating chi effectively.Make by all-metal with the screw that one section chi shell offsets, the thin end of the screw that offsets with adjacent chi shell studs with rubber or plastic pellet, and when chi shell and guide securement bar take place relatively when flexible, the screw that studs with rubber or plastic pellet can be mobile slightly, make flexible unrestrictedly, avoided the distortion of grating chi.Between adjacent two sections chi shells rubber sheet gasket is housed, under the chi shell expands with heat and contract with cold situation, still can keeps the sealing of seam crossing.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
As shown in Figure 1, the grating chi is docked from beginning to end successively by multistage chi shell 3 and multistage Grating glass 5 and is linked to be a straight line, and the length of every section grating chi is about 1 meter～1.2 meters, can select the hop count of grating chi according to actual needs arbitrarily.Every section grating chi is connected with the lathe (not shown) by a plurality of braces, and first brace of arbitrary section grating chi is fixedly connected 7, fixedlys connected with lathe, and all the other each braces flexibly connect with lathe in the vertical for flexibly connecting sheet 8.As shown in Figure 2, read head 1 and Grating glass 5 are arranged in the chi shell 3.
Connect by two guide securement bars 11 between adjacent two sections chi shells 3 arbitrarily.As shown in Figure 3, Figure 4, the xsect of guide securement bar 11 is " T " font, and four horizontal screws 12 are arranged above.Correspondingly, two gathering sills 31 are arranged in the chi shell 3, see Fig. 5, the notch of gathering sill 31 is narrower than the width in the groove, and is also narrow than the widest part of guide securement bar 11; Each guide securement bar 11 is embedded in the corresponding gathering sill 31.Four screws stretch into and pass each screw outside chi shell 3, the inwall of the gathering sill 31 of two screws and one section chi shell is inconsistent, and the gathering sill inwall of other two screws and adjacent chi shell is inconsistent.Consider that temperature variation can cause relative flexible between chi shell 3 and the guide securement bar 11; make by all-metal with two screws that a chi shell offsets; the thin end of two screws in addition that offsets with adjacent chi shell studs with plastic pellet or rubber grain (not shown), relatively moves so that can produce between chi shell 3 and the guide securement bar 11.In order to guarantee the linearity of grating chi behind the spreading better, the notch of two gathering sills lays respectively on the chi shell on orthogonal two sides, and the screw that promptly passes corresponding guide securement bar is perpendicular.
A rubber sheet gasket 9 identical with chi shell shape of cross section is housed between two sections adjacent chi shells 3, and there are a plurality of protruding grains 91 both sides of rubber sheet gasket 9, as Fig. 6, shown in Figure 7.A plurality of shrinkage pools 32 are arranged on the end face of chi shell 3, and the protruding grain 91 of each on the rubber sheet gasket 9 embeds in the corresponding shrinkage pool 32.Can effectively solve the sealing problem of extension grating ruler seam crossing like this.The two ends of full chi should have end cap 6.
