Description
【Technical field】
The utility model is related to field of measuring technique, and in particular to a kind of to be used to detect aperture internal diameter, the length survey of depth
Measure device.
【Background technology】
Dial gauge is that the B.C. Ames in the U.S. was made in 1890.It is usually used in Geometrical Error and thin tail sheep
Linear measure longimetry.100 evenly divideds are printed with the round dial of dial gauge, i.e., each scale division value is equivalent to gauge rod movement 0.01
Millimeter.Change gauge head shape and be equipped with corresponding support, can be made into the deformation kind of dial gauge, such as thickness dial gauge, depth hundred
Divide table and dial bore gage etc..Such as replace rack to can be made into lever indicator and dial test indicator with lever, its indication range compared with
It is small, but sensitivity is higher.In addition, their gauge head can be rotated in certain angle, the measurement of different directions is adapted to, structure is tight
Gather.They are applied to measure the Geometrical Error of common dial gauge is difficult to measure cylindrical, aperture and groove etc..
Existing dial gauge is generally by groups such as gauge head, gauge rod, antirattle spring, rack, gear, hairspring, round dial and pointers
Into.Its operation principle, is, by the small rectilinear movement of measuring staff caused by measured size, to amplify by gear drive, is changed into finger meter and exists
Rotation on dial, so as to read the size of measured size.Dial gauge is to utilize rack pinion or lever-gear transmission, will be surveyed
The straight-line displacement of bar is changed into the measurement instrument of the angular displacement of pointer.
The dial gauge of prior art is enlarged into pointer by gear drive and shown in dial, and one side dial plate is read more
It is cumbersome；The accuracy of another aspect dial gauge is limited by Gearmaking Technology, and influences dial gauge actual read number, and this reading passes through
Gear amplification causes digital error interval to become big；Another further aspect, gear is used for a long time abrasion and is also easily caused dial gauge at one section
Between declined using rear Numerical accuracy.
【Utility model content】
In order to overcome the shortcomings of existing technology, the utility model provides a kind of dial gauge, measurement bar displacive transformation Cheng Li
Change, change into displacement data by force sensor measuring stress, then by stress, and show by display screen, device operation
Simply overcome the problem of existing dial gauge measurement accuracy declines and be inaccurate.
The utility model uses the technical scheme to be：Dial gauge, its housing side is provided with below handle, housing provided with measurement
There is a circular hole in the middle part of pedestal, measurement pedestal, housing front, which is provided with display screen, housing, a battery tray, and housing central section is provided with one
Force snesor, force snesor circuit attachment force conversion calculator, power conversion calculator connection display screen, battery tray circuit connection position
In the switch outside housing and power conversion calculator, force snesor lower end connects an axis, and axis is socketed a spring, and spring one end connects
Measurement bar fixed seat is connect, measurement bar fixed seat locking measurement bar, measurement bar passes through measurement pedestal circular hole, measurement bar top measurement head
In circular arc concave surface.
Wait when in use and open switch, by measurement base seating in tested aperture horizontal plane, measurement bar is deeply tested in aperture
Power is transmitted force snesor by portion, measurement bar stress to spring-compressed, spring, and the power of measurement is converted and calculated by force snesor by power
Device computational length, and length value is shown by display screen.Different measurement bars can be changed according to measured object aperture.
The beneficial effects of the utility model are：The present apparatus changes metering system, passes through computational length after force snesor stress
Numerical value, simple to operate, numerical value is more directly perceived, and the present apparatus is amplified different from conventional gears, because of Gear Processing precision and will not be made
Cause the inaccurate defect of measured value with abrasion.
To make to be further understood that feature of the present utility model and technology contents, the utility model embodiment is referred to and attached
Figure, but appended drawings and examples are only for reference with illustrating to use, and are not that the utility model is any limitation as.
【Brief description of the drawings】
Fig. 1 is the utility model structural representation；
In figure, 1- housings；2- handles；3- display screens；4- sensors；5- power converts calculator；6- measures pedestal；8- is measured
Bar；9- measurement heads；10- measurement bar fixed seats；11- battery trays；12- is switched.
【Embodiment】
The utility model is described further with reference to embodiment：
Embodiment 1, dial gauge, its housing (1) side is provided with provided with measurement pedestal (6) below handle (2), housing (1), is surveyed
There is a circular hole in the middle part of amount pedestal (6), housing (1) front, which is provided with display screen (3), housing (1), a battery tray (11), housing
