Abstract
The utility model discloses a hole center distance measuring tool. The hole center distance measuring tool comprises a primary ruler and an auxiliary ruler. The ruler body of the primary ruler is provided with scale marks. The auxiliary ruler sleeves the primary ruler. The auxiliary ruler can move freely along the ruler body of the primary ruler and can be fixed at a certain position on the primary ruler by tightening a locking screw. One end of each of the auxiliary ruler and the primary ruler is provided with a ruler head. Each of the ruler heads is equipped with a ball head. The hole center distance measuring tool further comprises sleeves. The outer surface of each sleeve is fitted with the face of a tested hole of a workpiece. The inner semicircular nest surface along the center line of each sleeve is fitted with the spherical surface of one corresponding ball head, and the spherical center of the inner semicircular nest surface and the spherical center of the spherical surface are superposed. Moreover, the other end of the primary ruler is equipped with a baffle plate. The beneficial effects of the utility model reside in that the hole center distance measuring tool is simple and reasonable in structure, accurate in measurement, greatly improved in detection efficiency, and convenient to use.
Description
[technical field]
The utility model relates to fields of measurement, relates in particular to a kind of inclined hole hole heart that intersects apart from measuring measurer.
[background technology]
In Design of Measuring Tools, often can run into the angled relation of interplanar of part, as shown in Figure 1, and in two planes, be often drilled with again the hole of vertical plane, and the situation of distance between two hole hearts often that we will measure.
[summary of the invention]
For the shortcoming of prior art, it is a kind of simple and reasonable that the purpose of this utility model is to provide, and the hole heart easy to use is apart from measuring measurer.
The technical solution adopted in the utility model is: a kind of hole heart, apart from measurer, is characterized in that: comprise the graduated main scale of blade band and be enclosed within the secondary chi on main scale, secondary chi moves freely along main scale blade, is fixed on a certain position of main scale by tightening lock-screw; All there is chi head one end of secondary chi and main scale, on chi head, bulb is housed, and also comprises cover, and cover outside surface coordinates with workpiece measured hole face, and along overlapping, the interior semicircle nest face of center line and the sphere of bulb coordinate and two centre ofs sphere overlap;
Further, the main scale other end is provided with baffle plate.
The beneficial effects of the utility model are: simple and reasonable, easy to use, measure accurately, greatly improve detection efficiency.

[embodiment]
Referring to accompanying drawing, the utility model has adopted a kind of hole heart apart from measurer, it is characterized in that: comprise the graduated main scale of blade band and be enclosed within the secondary chi on main scale, secondary chi moves freely along main scale blade, is fixed on a certain position of main scale by tightening lock-screw; All there is chi head one end of secondary chi and main scale, on chi head, bulb is housed, and also comprises cover, and cover outside surface coordinates with workpiece measured hole face, and along overlapping, the interior semicircle nest face of center line and the sphere of bulb coordinate and two centre ofs sphere overlap;
Further, the main scale other end is provided with baffle plate.
When work, cover is pressed into respectively in tested workpiece measured hole, then two bulbs of bulb slide calliper rule is put into successively to the semicircle nest of cover, adjusting chi head closely cooperates the interior semicircle nest of bulb and cover, finally tighten lock-screw and carry out reading, draw a measured value, measure rear grip and take out.
The preferred embodiment that this utility model has been described at this, comprises that inventor is for implementing known optimal mode of the present utility model.The change of preferred embodiment is apparent for those of ordinary skills reading after above-mentioned explanation.Inventor wishes the rationally such change of application of those of ordinary skill, and inventor thinks and clearly states different application at this and also can realize the utility model.Therefore, the utility model comprises all modifications and the equivalents of the purport of quoting in the claim of enclosing, and this allows in applicable law.In addition, any combination of all possible change of above-mentioned key element is also comprised by the utility model, unless pointed out in addition or obvious contradiction in context at this.
Claims (2)
1. the hole heart, apart from a measurer, is characterized in that: comprise the graduated main scale of blade band and be enclosed within the secondary chi on main scale, secondary chi moves freely along main scale blade, is fixed on a certain position of main scale by tightening lock-screw; All there is chi head one end of secondary chi and main scale, on chi head, bulb is housed, and also comprises cover, and cover outside surface coordinates with workpiece measured hole face, and along overlapping, the interior semicircle nest face of center line and the sphere of bulb coordinate and two centre ofs sphere overlap.
2. the hole heart, apart from measurer, is characterized in that as claimed in claim 1: the main scale other end is provided with baffle plate.
