Abstract
The invention relates to the technical field of mechanical measurement devices, in particular to a hole center distance measurement device for perpendicularly-crossed holes. A first plug gauge is arranged and sequentially provided with a first measurement section, a second measurement section and a third measurement section from left to right. The hole center distance measurement device for the perpendicularly-crossed holes can conduct detection easily and measurement accuracy is high.
Description
Technical field
The present invention relates to mechanical measuring device technical field, particularly relate to the hole heart in the hole that intersects vertically apart from measurement mechanism.
Background technology
With the workpiece in the hole that two intersect vertically, there is accuracy requirement to the size of the centre distance of holes; Will there is its own shortcomings in the intersect vertically centre distance in hole of current measurement measurer measuring workpieces two: 1) because two intersect vertically hole not at grade, measure two the intersect vertically centre distance in hole comparatively difficult, 2) after measuring, measuring accuracy is lower, 3) in measuring process in enormous quantities, comparatively waste time and energy.
Summary of the invention
The object of this invention is to provide and a kind of easily to detect, the hole heart in what measuring accuracy was high intersect vertically hole is apart from measurement mechanism.
Technical scheme of the present invention is as follows:
Intersect vertically the hole heart in hole apart from measurement mechanism, comprises the first feeler gauge; Described first feeler gauge is provided with the first measuring section, the second measuring section, the 3rd measuring section from left to right successively.
Described measurement mechanism also comprise with the first feeler gauge with the use of the second feeler gauge, this feeler gauge one end is not-go-end, and the other end is go side; Described go side external diameter is less than not-go-end external diameter.Second feeler gauge and the first feeler gauge with the use of.
Annular groove is provided with between described first measuring section and the second measuring section; Annular groove is provided with between described second measuring section and the 3rd measuring section.Owing to being provided with annular groove, the first measuring section, the second measuring section, the 3rd measuring section effectively can be distinguished.
The invention has the beneficial effects as follows: the present invention inserts in two holes intersected vertically by the first feeler gauge and the second feeler gauge respectively, realize the measurement to the hole centre distance that two intersect vertically, what measuring process was become is easy, in measuring process in enormous quantities, save Measuring Time, improves and measures efficiency; Second feeler gauge two ends are respectively not-go-end and go side, adopt not-go-end and go side measuring accuracy higher.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Wherein: Fig. 1 is structural representation of the present invention;
Fig. 2 is the first feeler gauge structural representation in the embodiment of the present invention 3;
Fig. 3 is the second feeler gauge structural representation in the embodiment of the present invention 3;
In accompanying drawing, 1 is the first feeler gauge, and 2 is the first measuring section, and 3 is the second measuring section, and 4 is the 3rd measuring section, and 5 is the second feeler gauge, and 6 is go side, and 7 is not-go-end, and 8 is annular groove, 9 high violent steel.
Embodiment
Embodiment 1
Shown in Fig. 1-Fig. 3, the hole heart in the hole that intersects vertically, apart from measurement mechanism, comprises the first feeler gauge 1; Described first feeler gauge 1 is provided with the first measuring section 2, second measuring section 3, the 3rd measuring section 4 from left to right successively; The radius of described first measuring section is greater than the hole diameter minimum limit of size, and is less than the radius of the second measuring section; The radius of the second measuring section is less than the radius of the 3rd measuring section; The radius of the 3rd measuring section is less than hole diameter maximum limit of size.Described measurement mechanism also comprises the second feeler gauge 5, and this feeler gauge one end is not-go-end 7, and the other end is go side 6; Described go side external diameter is less than not-go-end external diameter; Wherein go side is the second feeler gauge minimum limit of size, and not-go-end is the second feeler gauge maximum limit of size.
Before measurement, according to formula d=b-a+c, calculate basic size and the tolerance of the second feeler gauge diameter; Wherein d is the distance of workpiece small hole least significant end to macropore least significant end, and b is the second feeler gauge diameter, and a is hole diameter, and c is hole heart distance.
During measurement, the first measuring section, the second measuring section, the 3rd measuring section are inserted in workpiece small hole successively, be used in the minimum measuring section of aperture clearance fit and insert in aperture; Second feeler gauge go side, not-go-end are inserted in macropore successively, if not-go-end is only crossed in go side, the centre distance of holes is qualified again.
Embodiment 2
According to aforementioned manner, in order to easily be distinguished by first, second, third measuring section when measuring, preferably, between described first measuring section and the second measuring section, be provided with annular groove 8; Annular groove is provided with between described second measuring section and the 3rd measuring section.Owing to being provided with annular groove, making to produce between first, second, third measuring section to cut off, can effectively distinguish first, second, third measuring section.
Embodiment 3
On basis according to embodiment 1, in order to increase the serviceable life of the first feeler gauge and the second feeler gauge, preferably, first, second, third measuring section outside surface of described first feeler gauge is provided with potassium steel 9 (or adopting platinum); The outside surface of described second feeler gauge go side, not-go-end is welded with potassium steel (or adopting platinum).Because the violent steel of height belongs to the Development of Wear Resistant Steel of high strength, be mainly used in the bad working environments conditions such as needs withstand shocks, extrude, material wearing and tearing, therefore the violent steel of one floor height be set at the position of the first feeler gauge and the second feeler gauge Long Term Contact and effectively can prevent first, second feeler gauge Long Term Contact and the problem causing measuring accuracy to reduce of wearing and tearing; Same due to platinum have that ductility is strong, refractory, rub resistance, characteristic that is corrosion-resistant, at high temperature chemical stabilization, therefore one deck platinum is set at the position of the first feeler gauge and the second feeler gauge Long Term Contact and effectively can prevents first, second feeler gauge Long Term Contact and the problem causing measuring accuracy to reduce of wearing and tearing.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
