Abstract
The utility model discloses a measuring rod for measuring the intersection point of the axis of the cylinder cover inclined hole and the plane comprising a rod; one end of the rod is equipped with a taper head and the point angle equals to the difference of 180 degrees minus twice of the included angle of the inclined hole axis projection and the cylinder cover baseplane. The taper head is equipped with a plurality of small holes. The utility model boasts of simple structure, high-precision measurement and wide application range.
Description
Technical field
The utility model relates to a kind of survey instrument, relates in particular to a kind of inclined hole axis of engine cylinder cap fuel injector and measurement rod of plane point of intersection position measured.
Background technology
In the engine process industry, for cylinder cap fuel injector inclined hole axis and cylinder cap baseplane intersection point distance to pin-and-hole (measuring basis plane), be with measured hole back gauge method at present, promptly arrive the distance of certain reference field with the limit in this hole of gage measuring, indirect calculation goes out the axial location in this hole, and its resultant error is bigger.
The utility model content
At the deficiencies in the prior art, the utility model provides a kind of measurement rod of measuring cylinder cover slant hole axis and plane point of intersection position, and it is simple in structure and can measure cylinder cap fuel injector inclined hole axis and the cylinder cap baseplane intersection point distance to the measuring basis plane exactly.
To achieve these goals, the utility model provides a kind of measurement rod of measuring cylinder cap fuel injector inclined hole axis and cylinder cap baseplane position of intersecting point, comprise barred body, be provided with conical head at described barred body one end, the angle of the awl point of described conical head is angle poor of the baseplane of 180 ° of inclined hole axis projections that deduct twice and cylinder head.
As a kind of improvement of the present utility model, on described conical head, offer some apertures.
The diameter of described barred body is slightly less than the diameter of described measurement inclined hole.Preferably, the diameter of barred body be described measurement inclined hole diameter dimension 90～98%.
Owing to adopt above-mentioned technical scheme, the utlity model has following beneficial effect:
1, simple in structure;
2, measuring accuracy height is to satisfy the debugging requirement of hole process equipment and frock;
3, applied widely, applicable to the measurement of through hole or blind hole.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Description of drawings
Fig. 1 is a user mode synoptic diagram of the present utility model;
Fig. 2 is a structural representation of the present utility model.
Mark the following drawings mark thereon in conjunction with the accompanying drawings:
The 1-barred body; The 2-conical head; The 3-cylinder head; The 4-survey instrument; 5-measuring basis plane;
The 6-aperture; The baseplane of 7-cylinder head.
Embodiment
As shown in Figure 1, the utility model is measured the measurement rod of cylinder cover slant hole axis and plane point of intersection position, comprise barred body 1, be provided with conical head 2 at barred body 1 one ends, the angle [alpha] of the awl point of conical head 2 is angle β poor of the baseplane 7 of 180 ° of inclined hole axis projections that deduct twice and cylinder head 3, i.e. α=180 °-2 β.
As shown in Figure 2, on conical head 2, offer some apertures.When the hole that will measure is the region between the heart and the diaphragm hole, will measure rod and turn 180 °, conical head outwards inserts in the region between the heart and the diaphragm hole.Can't take out from the other end after rod puts in owing to measuring, be used for extract measurement rod at the aperture 6 of measuring processing on the excellent conical head 2 this moment.The diameter of barred body 1 is slightly less than the diameter of inclined hole to be measured, to be convenient for measuring the plug of rod.Preferably, the diameter of barred body 1 be described measurement inclined hole diameter dimension 90～98%.
Principle of work of the present utility model is, measure the axis that rod is simulated the hole with one, different according to the projection of diplomatic inclined hole axis with the angle of Plane intersects, an end of measuring rod is worn into certain cone angle, after the measurement rod is put inclined hole into, the plain line that guarantees this cone angle remains parallel with measuring basis face 5, adjusts the overhang of measuring rod 1, just can find the intersection point on axis and plane.The effect of this measuring technique is that method that can be fairly simple is measured the crossing point of axes size.The application of this device will be measured by the hole back gauge before will changing, indirect calculation, or the complicated phenomenon of measuring inclined hole axis and plane point of intersection of three coordinate machine.
As shown in Figure 2, be user mode synoptic diagram of the present utility model.Measure the inclined hole axis and the cylinder head baseplane intersection point of certain type cylinder head 3 fuel injector, the inclined hole diameter of cylinder head 3 fuel injectors is φ 10mm, and the projection of inclined hole axis becomes 65 ° to intersect with the cylinder head basal surface.The end that to measure rod before the measurement is earlier worn into the conical head of 50 ° (180 °-2 * 65 °=50 °).To measure rod during measurement and put in from inclined hole outlet, measuring the plain line of cone of rod like this, parallel with the cylinder head basal surface (the cylinder head baseplane does not have process redundancy at this moment, and an available block pressur plate flattens; If process redundancy is arranged, can be processed into a boss with in the middle of the pressing plate, the height of boss just equals the process redundancy on this plane).50 ° of conical surfaces of cone plain line parallel with measuring basis is exactly the intersection point plane on axially bored line and plane like this.By using survey instrument 4 to measure the position dimension at this parallel plain line place, just drawn the size of diplomatic inclined hole axis and plane point of intersection again.
It should be noted that at last: above example only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this instructions has been described in detail the utility model with reference to each above-mentioned example,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
