Description
Technical field
The utility model is related to a kind of device for measuring hemispherical head surface shape deviations, and it belongs to pressure vessel detection
Technical field.
Background technology
Most of pressure vessel is mainly made up of cylinder and end socket, so end socket is most common part in pressure vessel
One of.End socket of different shapes under pressure, make a world of difference by stress distribution, and stress level differs larger, end socket surface shape
Shape dimensional discrepancy is larger, can cause larger stress increment, so as to cause local stress to exceed acceptability limit value, causes envelope
Head failure.So pressure container standard specification has strict requirements to the form variations of end socket, but the size to end socket is examined
In testing, the surface shape deviations of end socket do not have corresponding survey tool, can only be by GB/T25198-2010 for hemispherical head
《Pressure vessel head》Regulation checked using the full-scale model that inside contracts of band gap, and the cumbersome and essence of inspection
Exactness is not high.For an enterprise, end socket specification used is a lot, if each specification will make a full-scale interior sample
Plate, so can then increase the cost of enterprise.
The content of the invention
The utility model for pressure vessel in the prior art the detection of hemispherical head surface shape deviations it is cumbersome,
There is provided a kind of device for measuring hemispherical head surface shape deviations for the low deficiency of accuracy.
The technical scheme that the utility model solves above-mentioned technical problem is as follows：
A kind of device for measuring hemispherical head surface shape deviations, including support beam, rotating bar and chaining pin with a scale
Device；The two ends of the support beam are provided with locating piece, and the rotating bar is fixed on the center of support beam with bearing pin, can turn around bearing pin
Dynamic, the length of rotating bar can be adjusted according to the size of hemispherical head；The chaining pin device is located at the end of rotating bar.
On the basis of above-mentioned technical proposal, the utility model can also do following improvement.
Further, the chaining pin device includes spring, scale, magnetic patch and with graduated chaining pin；The spring, magnetic patch and
Chaining pin is located at the inside of rotating bar, and the side of the chaining pin is provided with the side pointer being located in the middle of two magnetic patch；The scale passes through solid
Clamp is fixed in rotating bar.
Compared with prior art, the beneficial effects of the utility model are：Utilize surface of the mechanical mechanism to hemispherical head
Form variations are measured, and simple in construction, easy to operate, measuring accuracy is high；Without full-scale interior model, greatly reduce
Entreprise cost is paid wages.

Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit scope of the present utility model.
Support beam 1 is marked with scale, and placement position of the present utility model is determined according to the diameter of scale value and measured end socket
Put；Locating piece 4 is used to fix position of the present utility model；It is circular that rotating bar 5 guides its end to draw.Chaining pin device 6, is used to refer to
Show end socket evagination and indent amount, be made up of spring 7, scale 8, magnetic patch 9, geometrical clamp 10, chaining pin 11 and side pointer 12, wherein, mark
Chi 8 can be moved and fixed by geometrical clamp 10, and chaining pin 11 is marked with scale, for indicating the amount that chaining pin 11 stretches out from rotating bar 5,
Side pointer 12 on chaining pin 11, for determining dead-center position of the chaining pin 11 in scale 8, while being stirred in the moving process of chaining pin 11
Magnetic patch 9 is moved, and magnetic patch 9 can indicate that end socket evagination and indent amount.
Embodiment：
Exemplified by measuring surface shape deviations of the internal diameter for 400mm hemispherical head, first according to the scale in support beam 1
The diameter of value and measured end socket determines placement location of the present utility model, and fixes the utility model with locating piece 4, by chaining pin
11 extension elongation is set to 5mm；It is 195mm that adjustment, which rotates pole length, and the zero graduation of adjustment scale 8 aligns with side pointer 12, and
Fixed with geometrical clamp 10, two magnetic patch 9 are moved at side pointer 12, rotating bar is then turned into the other end by one end, surveyed
After having measured, two magnetic patch 9 corresponding scale value on scale 8 is the maximum evagination value and maximum interior valley of measured end socket.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc. should be included in guarantor of the present utility model
Within the scope of shield.
