Abstract
The utility model belongs to the detection device technology field, to be specific, relates to a cylinder cover fuel injector detection tool comprising a pedestal. The front part of the pedestal is provided with a reference seat, and the front part of the reference seat is provided with an extension rod. The front part of the extension rod is provided with a positioning rod, a front end of which is in the shape of a cone. The distance between the cone-shaped head part of the positioning rod and the plane of the front end of the extension rod meets the standard of the drawing. The coaxiality of the reference seat and the positioning rod is 0.02mm. The diameter of the reference seat is 0.05-0.08mm smaller than a diameter of a large hole of a fuel injector, and the diameter of the positioning rod is 0.05-0.08mm smaller than a diameter of a small hole of the fuel injector. The cylinder cover fuel injector detection tool is advantageous in that the design is reasonable, and the position and the size precision of the fuel injector holes can be detected; compared to the prior art, the costs and the operation time can be saved, the requirements on the manual operation can be lowered, no calculation is required, and the production efficiency can be improved.
Description
Technical field
The invention belongs to inspection machine technical field, be specifically related to a kind of cylinder head fuel injector hole cubing.
Background technology
In engine production producer, cylinder head fuel injector hole is all the emphasis in process, and the position of oil injector hole and size relationship are struck sparks to engine, can startup be carried out smoothly, therefore,, to the cylinder cap processing, measure the size of oil injector hole and the position operation that is absolutely necessary.
But the position of oil injector hole, size are mended very good measurement, as shown in Figure 2, fuel injector passes and goes from fuel injector macropore 3, arrive fuel injector aperture 6, fuel injector 7 has dimensional requirement H with top surface of cylinder cover 17 foremost always, and normal method cannot measuring height, and oil injector hole machined surface 2 is blanks, surface is uneven, and cannot serve as measuring basis, is all generally that fuel injector is installed into measurement, need dismounting, operate more loaded down with trivial detailsly, measure after finishing and need the Angular Dimension that converts, work efficiency is not high.
Summary of the invention
For addressing the above problem, the utility model discloses a kind of cylinder head fuel injector hole cubing, can detect position degree and the size of oil injector hole, saved cost and running time, improved work efficiency.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of cylinder head fuel injector hole cubing: it is characterized in that: comprise base, base front is provided with reference seat, reference seat front is provided with extension rod, extension rod front is provided with backstay, backstay front end is tapered, and described backstay conical nose meets drawing standard apart from the distance of transverse plane before extension rod, and the right alignment of described reference seat and backstay is 0.02mm, reference seat diameter is than the little 0.05-0.08mm of the large bore dia of fuel injector, and backstay diameter is than the little 0.05-0.08mm of fuel injector hole diameter.
As a modification of the present invention, described extension rod and backstay root are provided with relief groove.
As a modification of the present invention, described backstay conical nose is through Quenching Treatment.
As a modification of the present invention, described backstay conical nose is in fuel injector aperture.
As a modification of the present invention, the axis of described cubing becomes 22.5-23.5 ° with cylinder cap bottom surface.
The invention has the beneficial effects as follows:
Cylinder head fuel injector of the present invention hole cubing, reasonable in design, not only the position degree of oil injector hole can be detected but also the dimensional accuracy of oil injector hole can be detected, compared with traditional detection method, the cost-saving and running time, reduced manually-operated requirement, without calculating, enhance productivity.

Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention.
As shown in the figure, a kind of cylinder head fuel injector of the present invention hole cubing: comprise base 8, base 8 fronts are provided with reference seat 9, reference seat 9 fronts are provided with extension rod 11, extension rod 11 fronts are provided with backstay 13, backstay 13 front ends are tapered, described backstay conical nose 14 meets drawing standard apart from the distance of transverse plane 16 before extension rod, described reference seat 9 is 0.02mm with the right alignment of backstay 13, reference seat 9 diameters are than the little 0.05-0.08mm of fuel injector macropore 3 diameter, and backstay 13 diameters are than the little 0.05-0.08mm of fuel injector aperture 6 diameter.
After cylinder head fuel injector hole processes, cylinder cap is cleaned up, be placed on test flat plate, cubing is passed and is gone from fuel injector macropore 3, backstay conical nose 14 arrives in fuel injector aperture 6 always, because described backstay conical nose 14 meets drawing standard apart from the distance of the front transverse plane 16 of extension rod 11, backstay conical nose 14 is no more than cylinder cap bottom surface plane, reference seat 9 is fitted with fuel injector macropore 3, backstay 13 is fitted with fuel injector aperture 6, the front transverse plane 16 of extension rod 11 is placed on reference field 4, cylinder cap is kept flat, cubing base 8 is for supporting, with pit gauge measure cylinder cap bottom surface 5 apart from backstay conical nose 14 foremost, the namely distance of measurement point 15, obtain the depth dimensions of oil injector hole, because reference seat 9 is 0.02mm with the right alignment of backstay 13, if the cylinder cap processing meets drawing requirement, cubing can easily insert, if cubing is inserted, do not enter or insert not on earth, illustrate that to process oil injector hole position not right, right alignment is not up to standard.
For measuring accuracy is improved, at described extension rod and backstay root, be provided with relief groove, there is not R angle, the front transverse plane of extension rod 11 and reference field 4 can be fitted completely, can not affect measuring accuracy.
In order to make cubing of the present invention durable in use, described backstay conical nose 14 is through Quenching Treatment.
In the present invention, the axis of described cubing and 5 one-tenth of cylinder cap bottom surfaces 22.5-23.5 °.
Technological means disclosed in this invention is not limited only to the disclosed technological means of above-mentioned embodiment, also comprises the technical scheme being comprised of above technical characterictic combination in any.
