Pass the rectangular elastomer of measurement linear displacement and survey for measuring object under test outer diameter, described one side for surveying son with test desk
Side abuts against, and survey is abutted with object under test and connect with measurement display module.
Further, the main body includes the first main body and the second main body, lower part and the first main body of second main body
Top fits.
Further, the measurement display module is set in the second main body, and the measurement body and test desk are all set in
In one main body.
Further, the measurement body is set between measurement display module and test desk.
Further, it is provided on the upper contact surface of the test desk several for preventing object under test to be adsorbed on contact surface
On groove.
Further, several groove spaced sets.
Further, skewed supporting block is provided with below the main body.
Further, the handle for being moved easily main body is provided on the two sides of the main body.
Further, be additionally provided with two pieces of reference blocks in the main body, another two avris of the test desk respectively with two pieces of bases
Quasi- block is corresponding to abut.
Preferably, the measurement display module is dial gauge, amesdial or displacement sensor.
The beneficial effect of the utility model embodiment is: substituting common survey block using rectangular elastomer to transmit measurement position
It moves linearly, since elastic force directly acts on object under test, object under test can be made to transport back and forth on the direction of elastic force
It is dynamic, i.e., it is for linear motion, beat will not be generated, therefore calibration can be oriented in the movement direction to it, it can be completely
Transmitting measurement linear displacement；Also, it is provided with measurement display module, user is facilitated to read measurement data in real time, it is very convenient；It surveys
Amount body can provide space with survey for rectangular elastomer and play good fixed function, and make good appearance, another
Aspect abuts against the avris for surveying son and test desk, and the stability of measurement can be improved.Therefore, the utility model design is closed
Reason, good appearance can reduce measurement error, and improving measurement accuracy realizes that measuring targets measure moderately goodly.
Detailed description of the invention
The utility model preferred embodiment is provided, with reference to the accompanying drawing the embodiments of the present invention are described in detail.
Fig. 1 is a kind of perspective view of high-precision external measuring instrument of the utility model embodiment；
Fig. 2 is a kind of top view of high-precision external measuring instrument of the utility model embodiment；
Fig. 3 is a kind of left view of high-precision external measuring instrument of the utility model embodiment.
Specific embodiment
- Fig. 3 referring to Fig.1, a kind of high-precision external measuring instrument of the utility model, including main body 1 are set in the main body 1
It is equipped with measurement body 2, measurement display module 3 and the test desk 4 for bearing object under test, is opened on an avris of the measurement body 2
There is accommodating hole and measures the rectangular elastomer 22 of linear displacement and for measuring determinand for transmitting in being provided in accommodating hole
Survey 21 of external diameter, the rectangular elastomer 22 and an avris of test desk 4 abut against, and survey 21 is supported with object under test
It connects and is connect with measurement display module 3.
Specifically, the object under test can be workpiece or other objects；
Preferably, the measurement display module 3 is dial gauge, amesdial or displacement sensor, and user is facilitated directly to carry out
Reading measures display module 3 certainly and is also possible to other similar readable devices.
Further, the main body 1 includes the first main body 11 and the second main body 12, the lower part and first of second main body 12
The top of main body 11 fits, that is, the whole height for disclosing the second main body 12 is above the first main body 11, occupies so empty
Between it is small, it appears have a sense of hierarchy, so that good appearance；Wherein, first main body 11 can be one piece of metal plate.
Further, the measurement display module 3 is set in the second main body 12, and the measurement body 2 and test desk 4 are respectively provided with
In in the first main body 11, so that the distribution of whole each component will not be crowded, it is sufficiently used available space, and in this way can
So that measurement display module 3 is closer from human eye, it is convenient to be read.
Common survey block is substituted using rectangular elastomer 22 to transmit measurement linear displacement, since elastic force directly acts on
On object under test, therefore object under test can make back and forth movement on the direction of elastic force, i.e., for linear motion, will not generate partially
Pendulum, therefore calibration can be oriented in the movement direction to it, it can completely transmit measurement linear displacement；Also, it is arranged
There is measurement display module 3, user is facilitated to read measurement data in real time, it is very convenient；Measuring body 2 can be 22 He of rectangular elastomer
It surveys son 21 space is provided and plays good fixed function, and makes good appearance, on the other hand make to survey son 21 and test desk 4
An avris abut against, the stability of measurement can be improved.Therefore, the utility model is designed reasonably, good appearance can reduce
Measurement error, improving measurement accuracy realize that measuring targets measure moderately goodly.
Further, the measurement body 2 is set between measurement display module 3 and test desk 4, therefore can will measure body 2
Two sides fixed well.
Further, it is provided with and several connects for preventing object under test to be adsorbed on the upper contact surface 41 of the test desk 4
Groove 42 in contacting surface 41, if not opening up groove 42, object under test is easy and upper 41 adhesion of contact surface, it has not been convenient to after a measurement
It is removed.
Further, several 42 spaced sets of the groove, setting spacing equally distributed in this way, can prevent determinand
Certain parts of body are trapped in groove 42, would not also generate absorption.
Further, it is provided with skewed supporting block 5 below the main body 1, since supporting block 5 is obliquely installed, because
This facilitates progress between object under test and test desk 4 close sturdy.
Further, the handle 6 for being moved easily main body 1 is provided on the two sides of the main body 1, can optionally by
Measuring instrument is moved to other positions, very convenient.
Further, be additionally provided with two pieces of reference blocks 7 in the main body 1, another two avris of the test desk 4 respectively with two pieces
Reference block 7 is corresponding to abut；Reference block 7 plays the role of fixation measuring platform 4, that is, fixs the initial position co-ordinates (base of test desk 4
It is quasi-).
The preferred embodiment of the utility model and basic principle is discussed in detail in the above content, but the utility model is simultaneously
It is not limited to above embodiment, those skilled in the art should be recognized that in the premise without prejudice to the spirit of the present invention
Under also have various equivalent variations and replacement, these equivalent variations and replacement both fall within the scope of the claimed invention
