Description
Technical field
The utility model relates to field of automobile, especially a kind of for detecting pipe fitting inner cone sealing surface taper
Cubing.
Background technique
The pipe fitting of automobile steering system is usually using cone sealing pipe joint, the direct shadow of quality of bevel sealing surface in pipe fitting
The taper of bevel sealing surface is very important parameter in the leakproofness of speaking pipe connector, especially pipe fitting, if the parameter does not conform to
Lattice, pipe fitting are easy to oil leak after tightening, and influence vehicle operation, bring security risk, so the detection to the parameter is very heavy
It wants.Currently, three-coordinates measuring machine is generallyd use to carry out pipe fitting taper inspection, but time-consuming, low efficiency, cost for this method
Height is unable to meet production needs.
Utility model content
For the problems in background technique, the utility model provides a kind of for detecting pipe fitting inner cone sealing surface taper
Cubing, to solve the problem of that bevel sealing surface taper testing cost is high in pipe fitting in the prior art, cannot quickly detect.
The purpose of this utility model is that technical solution in this way realizes that it includes:
It is a kind of for detecting the cubing of pipe fitting inner cone sealing surface taper, including cubing ontology, innovative point are: described
Cubing ontology sequentially form from left to right by section, holding section and stopped section；Described is by section truncated cone-shaped, axial direction by section
Length is equal to the axial length of bevel sealing surface in the pipe fitting, and diameter by section is gradually increased from left to right, by section
The diameter of left side is identical as the minimum diameter of bevel sealing surface in pipe fitting, and taper by section is equal to 24 ° 30 '；It is described to stop
Section is truncated cone-shaped, and the axial length of stopped section is equal to the axial length of bevel sealing surface in the pipe fitting, the diameter of stopped section from
Left-to-right is gradually reduced, and the diameter of the right side of stopped section is identical as the minimum diameter of bevel sealing surface in pipe fitting, stopped section
Taper is equal to 25 ° 30 '.
Further, the holding section is variable section structure body, big in the middle part of the radial dimension of the variable section structure body, two
Hold small, the outer peripheral surface of holding section is provided with annular knurl.
By adopting the above-described technical solution, the utility model has the advantage that the inner cone sealing due to pipe fitting
The taper nominal dimension in face is 25 °, and upper and lower deviation is respectively+30 ', -30 ', inner cone of the taper having a size of pipe fitting by section
24 ° 30 ' of the minimum limit of size of sealing surface, the taper of stopped section is having a size of the maximum limit of size of the interior bevel sealing surface of pipe fitting
25 ° 30 ', the minimum diameter of pass section and stop section is identical as the minimum diameter of interior bevel sealing surface of pipe fitting, by section and
The width of stopped section is of same size with the interior bevel sealing surface of pipe fitting, so when being tested the interior bevel sealing surface section of pipe fitting both
When can allow and by section be entirely enclosed in, while stopped section cannot be allowed to be entirely enclosed in again, illustrate the taper of the interior bevel sealing surface of pipe fitting
In the margin of tolerance, taper is qualified.It can be seen that detection tool structure described in the utility model is simple and convenient to operate, detection
Quickly, at low cost.
Detailed description of the invention
The Detailed description of the invention of the utility model is as follows.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is detection principle diagram.
In figure: 1, by section；2, holding section；3, stopped section.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
The cubing for being used to detect pipe fitting inner cone sealing surface taper as shown in Fig. 1, including cubing ontology, the cubing
Ontology sequentially forms by section 1, holding section 2 and stopped section 3 from left to right；Described 1 is by section truncated cone-shaped, by section 1 axis
It is equal to the axial length of bevel sealing surface in the pipe fitting to length, by section 1 diameter is gradually increased from left to right, by section
The diameter of 1 left side is identical as the minimum diameter of bevel sealing surface in pipe fitting, and by section 1 taper is equal to 24 ° 30 '；It is described
Stopped section 3 is truncated cone-shaped, and the axial length of stopped section 3 is equal to the axial length of bevel sealing surface in the pipe fitting, stopped section 3
Diameter is gradually reduced from left to right, and the diameter of the right side of stopped section 3 is identical as the minimum diameter of bevel sealing surface in pipe fitting, only
The taper for crossing section 3 is equal to 25 ° 30 '.Holding section 2 is variable section structure body, big in the middle part of the radial dimension of the variable section structure body,
Small in ends, the outer peripheral surface of holding section 2 is provided with annular knurl.
In the present embodiment, bevel sealing surface taper design is having a size of 25 ° ± 30 ' in pipe fitting.
As shown in Fig. 2, the taper of conical surface A is 24 ° 30 ' in figure, and the taper of conical surface B is 25 ° 30 ', and pipe fitting inner cone is close
Cover taper is all denoted as qualification in the range of A-B.
In use, tester holds the holding section of this cubing, pass section and stop section are sequentially placed into pipe fitting to be measured
Bevel sealing surface section is tested, and determines whether bevel sealing surface taper is qualified in pipe fitting according to following result:
1, bevel sealing surface taper is qualified in following situation pipe fittings
It can be by section entirely enclosed in the inner cone seal section of pipe fitting, while stopped section could not fully fit into the inner cone of pipe fitting
Seal section；
2, bevel sealing surface taper is unqualified in following two kinds of situation pipe fittings
1) it, by section could not fully fit into the inner cone seal section of pipe fitting；
2), stopped section can be entirely enclosed in the inner cone seal section of pipe fitting.
