Description
Technical field
The utility model relates to rail card measuring device tool.
Background technology
Clearly having stipulated in the production standard of rail must project be checked to symmetry, rail height, rail head width, web of the rail thickness, flange of rail width, the flange of rail limit of rail transversal section be thick etc.Existing method is to adopt standard jig that rail is pursued Zhi Kaliang, the corresponding a kind of standard jig of same inspection item.Have now and be used to check that the inspection model of rail transversal section symmetry is divided into positive symmetry inspection model and negative symmetry inspection model.Will use positive symmetry to check model and negative symmetry check after model is to the rail amount of card to determine whether rail transversal section symmetry is qualified, and not only efficient is low during inspection respectively, and required standard jig quantity is more.
The utility model content
The technical matters that the utility model solved provides a kind of auxiliary implement that the rail transversal section is checked that has the positive and negative symmetry audit function in rail transversal section simultaneously.
The technical scheme that solves the problems of the technologies described above is: the auxiliary implement that the rail transversal section is checked, comprise main body, the a part of edge wheel profile of this main body and the outline line of rail standard cross-section are identical substantially, on described edge wheel profile, be respectively equipped with rail head salient point and flange of rail slot to make way, the width of described flange of rail slot to make way is D1, when the rail head edge contact of described rail head salient point and described outline line, the distance that the flange of rail edge of described outline line and the described flange of rail are stepped down between the groove is D2, described D1, pass between the D2 is 0＜D2＜D1.
The beneficial effects of the utility model are: when using this utensil that the symmetry of rail transversal section is checked, after the rail head edge contact of rail head salient point and tested rail, if the distance D 3 that the flange of rail edge of tested rail and the described flange of rail are stepped down between the groove satisfies 0≤D3≤D1, judge that then symmetry is qualified, otherwise symmetry is defective.As seen, this auxiliary implement has the positive and negative symmetry audit function in rail transversal section simultaneously, save frequent change check model the time, increase work efficiency.
Description of drawings
Fig. 1,2 is two kinds of user mode figure of the application's auxiliary implement.
Fig. 3,4 is respectively the partial enlarged drawing at B place among A place among Fig. 1 and Fig. 2.
Be labeled as among the figure: main body 1, edge outline line 201, edge wheel profile 202, outline line 3, rail head salient point 4, flange of rail slot to make way 5, rail head edge 6, flange of rail edge 7, rail support rim 8, rail head circular arc contact 9, rail head circular arc line 10.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
It is pointed out that the rail in Fig. 1～4 is the standard cross-section rail, illustrate tested rail is not shown in the accompanying drawing.
As Fig. 1, the auxiliary implement that the rail transversal section is checked shown in 3, comprise main body 1, a part of edge wheel profile 201 of this main body 1 is identical substantially with the outline line 3 of rail standard cross-section, on described edge wheel profile 201, be respectively equipped with rail head salient point 4 and flange of rail slot to make way 5, the width of described flange of rail slot to make way 5 is D1, when described rail head salient point 4 contacts with the rail head edge 6 of described outline line 3, the distance that the flange of rail edge 7 of described outline line 3 and the described flange of rail are stepped down between the groove 5 is D2, described D1, pass between the D2 is 0＜D2＜D1.Physical relationship between D2 and the D1 is by the positive and negative deviation decision of rail transversal section symmetry.When using this utensil that the symmetry of rail transversal section is checked, when rail head salient point 4 with after the rail head edge 6 of tested rail contacts, when distance D 3 between the groove 5 satisfies 0≤D3≤D1 if the flange of rail edge 7 of tested rail and the described flange of rail are stepped down, judge that then symmetry is qualified, otherwise symmetry is defective; If the flange of rail edge 7 of tested rail contacts prior to its rail head edge 6 and the flange of rail of this utensil groove 5 of stepping down, judge that symmetry is defective.
For the width D 1 that makes flange of rail slot to make way 5 visual, make the tester can be directly just can judge magnitude relationship between D3 and the D1 accurately by visual observation, as shown in Figure 3, be provided with rail support rim 8 on the edge contour of main body 1, the spacing of described rail support rim 8 and described flange of rail slot to make way 5 equals the width D 1 of flange of rail slot to make way 5.Like this, when rail head salient point 4 with after the rail head edge 6 of tested rail contacts, as long as the zone of flange of rail edge 7 between rail support rim 8 and described flange of rail slot to make way 5 of tested rail, the relation of then satisfied certainly 0≤D3≤D1.If but the flange of rail edge 7 of tested rail judges that then symmetry is defective outside the zone between rail support rim 8 and the described flange of rail slot to make way 5 at this moment.Rail support rim 8 and flange of rail slot to make way 5 relative faces are the plane in Fig. 3, improve the accuracy of checking.
Shown in Fig. 1,2,4, another part edge wheel profile 202 of described main body 1 is identical substantially with the rail head circular arc line 10 of rail standard cross-section.Can check the tread circular arc degree of filling of rail by this edge wheel profile 202, further increase the function of auxiliary implement.
As shown in Figure 4, on described another part edge wheel profile 202, also be provided with a plurality of rail head circular arcs contact 9.By just can judge the tread circular arc degree of filling of rail more accurately to each the rail head circular arc contact 9 and the contact condition of the rail head circular arc line 10 of tested rail.
As shown in Figure 1, 2, described main body 1 is a platy structure.The mechanical processing tools moulding that described a part of edge wheel profile 201, another part edge wheel profile 202 and rail support rim 8 all cut by line.
