The utility model provides a kind of ring stiffness internal diameter measuring instrument, it is characterised in that: including two subframe bodies；Every width frame body includes a pressing plate, two guide rods perpendicular to pressing plate are fixed on pressing plate, guide rod passes through two through-holes set by a measuring staff, and there is spring to be set on guide rod, and both ends of the spring distinguishes contact on the outer end and measuring staff of guide rod, and the gauge head towards pressing plate is equipped in the middle part of measuring staff；One draw wire encoder is fixed on the middle part of a measuring staff, and the other end of the bracing wire of draw wire encoder is fixed on the middle part of another measuring staff.The utility model is used and is mounted on the displacement sensor of draw wire encoder form on the measuring staff of two profile forms, it is placed in the middle part of tubing, by being improved in this way by the effective Traditional movement sensors that reduce to the measurement error deformed in the middle part of tubing, the accuracy of pipe ring stiffness testing result is improved.
Description
Technical field
It is specifically a kind of for detecting the internal diameter of pipe ring stiffness the utility model relates to a kind of pipes detection device
The measuring instrument of variation.
Background technique
Tubing, such as pvc pipe, bellows etc., it is often necessary to carry out ring stiffness measurement and the soft experiment of ring, present tubing
During ring stiffness and the soft test of ring, ring stiffness is displaced the displacement using board itself, and there are error is larger or Magnetic gauge stand position
Displacement sensor cannot measure displacement among tubing, so that test data is inaccurate.It is inaccurate that experimenter can encounter internal diameter measurement
Really, the problems such as Magnetic gauge stand is insecure.
Summary of the invention
The utility model provides a kind of ring stiffness internal diameter measuring instrument, the purpose is to solve the disadvantage that the prior art, improves pipe
The accuracy of material ring stiffness testing result.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of ring stiffness internal diameter measuring instrument, it is characterised in that: including two subframe bodies；Every width frame body includes a pressing plate, pressure
Two guide rods perpendicular to pressing plate are fixed on plate, guide rod passes through two through-holes set by a measuring staff, is set in spring
On guide rod, and both ends of the spring difference contact is equipped with the gauge head towards pressing plate on the outer end and measuring staff of guide rod, in the middle part of measuring staff；
One draw wire encoder is fixed on the middle part of a measuring staff, and the other end of the bracing wire of draw wire encoder is fixed on another measuring staff
Middle part.
The utility model has the beneficial effect that
The utility model is used and is mounted on the displacement sensor of draw wire encoder form on the measuring staff of two profile forms,
It is placed in the middle part of tubing, misses effective reduction Traditional movement sensors to the measurement deformed in the middle part of tubing by improving in this way
Difference improves the accuracy of pipe ring stiffness testing result.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is utility model diagram.
Specific embodiment
In order to illustrate more clearly of the technical solution of the utility model, attached drawing needed in description will be made below
Simply introduce, it should be apparent that, the drawings in the following description are merely some embodiments of the present invention, for this field
For those of ordinary skill, without creative efforts, it can also be obtained according to these attached drawings other implementations
Example.
As shown in Figure 1:
The utility model includes two subframe bodies；Every width frame body includes a pressing plate 1, be fixed on pressing plate 1 two perpendicular to
The guide rod 3(of pressing plate 1 such as guide rod 3 is arranged on pressing plate 1), guide rod 3 passes through two through-holes set by measuring staff 2, in through-hole
Linear bearing can be installed, guide rod 3 cooperates linear bearing to slide, there is spring 4 to be set on guide rod 3, and 4 liang of spring
End difference contact is on the outer end and measuring staff 2 of guide rod 3.
The gauge head 5 towards pressing plate 1 is fixed in the middle part of measuring staff 2.One draw wire encoder 6 is fixed in a measuring staff 2
The other end in portion, the bracing wire 7 of draw wire encoder 6 is fixed on the middle part of another measuring staff 2.
In actual use:
The pressing plate 1 of two subframe bodies is separately fixed on two crossbeams 8 up and down of ring stiffness measuring machine, two measuring staffs 2 are put
Between two pressing plates 1, by the top edge of pvc pipe or the tube body 9 of bellows be inserted into pressing plate 1 above and gauge head above 5 it
Between, lower edge be inserted between following pressing plate 1 and following gauge head 5, then use 3 sets upper springs 4 of guide rod, guide rod 3 is across measuring staff 2
After be arranged on pressing plate 1.
After four guide rods 3 install, guide rod 3 is in the outside at 9 both ends of tube body, due to the effect of spring 4, measuring staff 2 above
It up presses, so that gauge head 5 above is pressed in the upper surface of 9 inner wall of tube body part, measuring staff 2 below is pressed down, thus following survey
First 5 are pressed in part below 9 inner wall of tube body.The upper surface of the outer wall of tube body 9 withstands on the lower surface of pressing plate 1 above, tube body 9 it is outer
The upper surface of following pressing plate 1 is scheduled below wall.
When ring stiffness measuring machine works, 8 upper and lower displacement of upper and lower two crossbeams, 1 pressure pipe body 9 of pressing plate makes its deformation, two surveys
First 5 are pressed, and two measuring staffs 2 shorten to intermediary movements, the bracing wire 7 of draw wire encoder 6, and draw wire encoder 6 obtains change in displacement
Data.
In this way, the displacement among tubing 9 can be accurately measured in ring stiffness measuring machine efforts, so that test data
Accurately.
Each embodiment in this specification is described in a progressive manner, the highlights of each of the examples are with other
The difference of embodiment, the same or similar parts in each embodiment may refer to each other.To the upper of the disclosed embodiments
It states bright, can be realized professional and technical personnel in the field or using the utility model.Various modifications to these embodiments pair
It will be apparent for those skilled in the art, the general principles defined herein can not depart from this reality
In the case where with novel spirit or scope, realize in other embodiments.Therefore, the utility model is not intended to be limited to this
These embodiments shown in text, and it is to fit to the widest scope consistent with the principles and novel features disclosed herein.
