Description
Technical field
A kind of flatness checking device is the utility model is related to, particularly a kind of novel planar degree detection means.
Background technology
For in the higher field of some precision prescribeies, the flatness and dimensional accuracy etc. of parts are equally important, but zero
The flatness of parts surface is all easily affected under each environmental factor, so as to cause error.At present, there are many passes the country
To be monitored it is exactly one of which by dial gauge in the device of flatness monitoring.The operation principle of dial gauge, be say it is tested
The small rectilinear movement of measuring staff caused by size, amplifies by gear drive, is changed into finger meter and is rotated on dial, so as to read quilt
Survey the size of size.Being monitored also using dial gauge has all many conditions, as dial gauge should be fixed by nonconservative force,
It should be carried out before use calibrating etc..
A kind of flatness measuring instrument that Chinese patent CN201320516422.5 is announced, the patent is by measuring pair of main body
The dial gauge in linea angulata direction, the levelness in the horizontal survey face of measurement body lower surface is monitored, dial gauge passes through survey
The locking nut being equipped with the locking hole that amount body side is set is fixed.The patent is sufficiently stable when using, dial gauge
Contact will not shake caused by movement and produce error, and can measure multiple places simultaneously, but due to being fixed due to dial gauge
In measurement main body, contact is the lower surface for exposing measurement main body, therefore the calibration to it has certain difficulty.
Utility model content
The purpose of this utility model is：In view of the above-mentioned problems, the utility model provide it is a kind of can calibrate automatically it is new
Type flatness checking device.
The technical solution adopted in the utility model is as follows：
A kind of novel planar degree detection means, including dial gauge, in addition to fixed block, the benchmark positioned at the bottom of fixed block
Plate, the fixed block are provided centrally with fixing hole, and the side of fixed block is provided with the positioning hole connected with fixing hole, positioning hole
Housing screw is inside fitted with, the upper and lower surface flatness error of the datum plate is less than, and datum plate is provided centrally with through hole, institute
The contact external diameter for stating dial gauge is more than the gauge rod external diameter of dial gauge, and the gauge rod of dial gauge through fixing hole and is inserted into from top to bottom
In through hole, the external diameter of the internal diameter of through hole and the contact of dial gauge matches, and the contact face of dial gauge and the lower surface of datum plate are neat
It is flat.
Preferably, the dial gauge is detachable be connected with fixed block and datum plate.
Preferably, the gauge rod gap of the fixing hole and dial gauge coordinates.
Preferably, the housing screw is hex screw.
In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are：
A kind of novel planar degree detection means in the utility model, can be calibrated, detachably so that it is just automatically
In carrying and clearing up, easy to use, cost is cheap.

Embodiment
All features disclosed in this specification, can be with any in addition to mutually exclusive feature and/or step
Mode combines.
Embodiment one
Shown in the present embodiment combination Fig. 1, Fig. 2 and Fig. 3, a kind of novel planar degree detection means, including dial gauge 1, also wrap
Fixed block 2, the datum plate 3 positioned at the bottom of fixed block 2 are included, the fixed block 2 is provided centrally with fixing hole 21, fixed block 2
Side be provided with the positioning hole 22 connected with fixing hole 21, housing screw 23 is fitted with positioning hole 22, the datum plate 3
Upper and lower surface flatness error is less than 0.01, and datum plate 3 is provided centrally with through hole 31, and the contact external diameter of the dial gauge 1 is big
In the gauge rod external diameter of dial gauge 1, the gauge rod of dial gauge 1 through fixing hole 21 and is inserted into through hole 31, through hole 31 from top to bottom
The external diameter of internal diameter and the contact of dial gauge 1 match, the contact face of dial gauge flushes with the lower surface of datum plate 3.
In use, after dial gauge 1 inserts the fixing hole 21 of fixed block 2, further through the through hole 31 of datum plate 3, make
, the contact face of dial gauge flushes with the lower surface of datum plate 3, and is compressed and consolidated by the housing screw 23 in positioning hole 22
It is fixed；The upper and lower surface flatness error of datum plate 3 is less than 0.01, the internal diameter of through hole 31 and the external diameter phase of the contact of dial gauge 1
Match somebody with somebody so that when instrument is gently moving to error dot, dial gauge reacts, and user can obtain margin of error by dial gauge 1
Value, after instrument removes error dot, because the external diameter of the internal diameter and the contact of dial gauge 1 of through hole 21 matches so that outside contact
Surface is adjusted to be flushed with the lower surface of datum plate 4, because the upper and lower surface flatness error of datum plate 4 is less than 0.01, is made
Dial gauge 1 is obtained to be calibrated.
