Plate, end socket negative camber sampling plate, the strip baffle plate are fixedly connected with strip end socket mouth straight flange internal diameter sampling plate top edge,
Strip end socket mouth straight flange internal diameter sampling plate lower limb is fixedly connected with arch end socket negative camber sampling plate, wherein strip end socket
Mouth straight flange internal diameter sampling plate length is more than arch end socket negative camber sampling plate linear edge length.
Preferably, the test sample plate is made up of two groups of end socket mouth straight flange internal diameter sampling plates and end socket negative camber sampling plate, and two
Piece test sample plate is fixedly connected along respective axis of symmetry intersection.
Preferably, the survey template edge is equipped with scale.
This utility model compared with prior art, its remarkable advantage：
（1）This utility model ellipse head detects model simple structure, and easy to make, tester is convenient to use, nothing
Need to train.
（2）This utility model ellipse head detection model coordinates ruler to use, and can accurately measure the shape of ellipse head
Error.
Below in conjunction with the accompanying drawings this utility model ellipse head detection model is described in further detail.
Description of the drawings
Fig. 1 is the structural representation that this utility model ellipse head detects model；
Fig. 2 is overlooking the structure diagram of this utility model with two panels test sample plate；
Fig. 3 is to measure the ellipse head detection model structural representation in ellipse head.
Specific embodiment
As shown in Figure 1：
A kind of ellipse head detects model, and including baffle plate 1, test sample plate 4, the test sample plate 4 includes end socket mouth straight flange internal diameter
Sampling plate 2, end socket negative camber sampling plate 3, the strip baffle plate 1 and 2 top edge of strip end socket mouth straight flange internal diameter sampling plate
It is fixedly connected, 2 lower limb of strip end socket mouth straight flange internal diameter sampling plate is fixedly connected with arch end socket negative camber sampling plate 3, its
Middle 2 length of strip end socket mouth straight flange internal diameter sampling plate is more than 3 linear edge length of arch end socket negative camber sampling plate；Had is ellipse
Circle 5 shape of end socket concaves, in order to entirely put test sample plate 4 in ellipse head 5 into, therefore the ellipse of the ellipse head 5 of standard
Circular curve per inwardly translates one section of equal distance along its normal direction（This segment distance takes 0.65%Di+5mm）And the song for being formed
Line exemplarily profile end socket negative camber sampling plate 3, keeps leaving between ellipse head detection 5 inwall of model and ellipse head
Gap, so can more accurately reflect the form variations of each position of ellipse head.
The test sample plate 4 is made up of two groups of end socket mouth straight flange internal diameter sampling plates 2 and end socket negative camber sampling plate 3, and two panels is surveyed
Model 4 is fixedly connected along respective axis of symmetry intersection.
4 edge of test sample plate is equipped with scale.
This utility model ellipse head detects the using method of model：
As shown in Figure 3：By the end socket mouth of ellipse head to be checked 5 horizontal positioned upward, by model be put into ellipse head 5 it
In, the larger or smaller position in selection gap, using ruler sample plate and the gap of ellipsoidal head inner surface, it is necessary to be edge
The normal direction measurement of model.When end socket evagination, the gap for measuring deducts（0.625%Di+5mm）1.25%Di is less than afterwards；When
During end socket indent, the gap for measuring deducts（0.652%Di+5mm）0.625%Di is less than afterwards, and the form variations of end socket are permitted in standard
Perhaps it is qualified in the range of.
This utility model ellipse head detection model is further elaborated with reference to embodiment：
Embodiment 1：
A kind of ellipse head detects model, and including baffle plate 1, test sample plate 4, the test sample plate 4 includes end socket mouth straight flange internal diameter
Sampling plate 2, end socket negative camber sampling plate 3, the strip baffle plate 1 and 2 top edge of strip end socket mouth straight flange internal diameter sampling plate
It is fixedly connected, 2 lower limb of strip end socket mouth straight flange internal diameter sampling plate is fixedly connected with arch end socket negative camber sampling plate 3, its
Middle 2 length of strip end socket mouth straight flange internal diameter sampling plate is more than 3 linear edge length of arch end socket negative camber sampling plate；Had is ellipse
Circle 5 shape of end socket concaves, in order to entirely put test sample plate 4 in ellipse head 5 into, therefore the ellipse of the ellipse head 5 of standard
Circular curve per inwardly translates one section of equal distance along its normal direction（This segment distance takes 0.65%Di+5mm）And the song for being formed
Line exemplarily profile end socket negative camber sampling plate 3, so can more accurately reflect the form variations of each position of ellipse head,
