Description
Technical field
The present invention relates to a kind of calibration of radius measurement instrument more particularly to the calibrations of radian table.
Background technique
Radian table is also known as radius gauge, apparatus for measuring radius, is widely used in the measurement of inside and outside cambered surface radius.It is shown by indicating value
Mode is divided into pointer dial type and digital display type.Currently, country's not yet publication is about the measurement and calibration specification of such instrument or metering
Vertification regulation does not also calibrate the instrument of its error of indication accordingly.
Summary of the invention
In order to fill up the instrument blank of the calibration radian table error of indication, the present invention provides a kind of measurable radian expression values
The calibration instrument of error.
The present invention is equipped with the high-resolution digital display micrometer head for measurement, installs the reference block and clamp screw of digital display micrometer head
Nail places the supporting table of tested radian table, for compressing the pressure of tested radian table for digital display micrometer head zeroing position to zero piece
Tight bar and compressed spring, pressed seat, for reference for installation block, supporting table, the bottom plate of compact heap and support leg.Digital display micrometer head peace
It fixes, zero piece is installed on reference block with screw, compressed spring is placed in mounting hole loaded on reference block and with holding screw
On compressor arm, compressor arm is placed in the through-hole of compact heap, and compact heap, supporting table, reference block are lock on bottom plate with screw-nut,
Support leg locks on the screw hole of bottom plate.
The present invention solves specific technical solution used by its technical problem: compact heap, supporting table, reference block screw
Nut check is fixed on bottom plate；Support leg locks on the screw hole of bottom plate, and bottom plate is maked somebody a mere figurehead, and facilitates the height of adjustment supporting table；
Digital display micrometer head is installed in the mounting hole of reference block and is fixed with holding screw, is installed on reference block to zero piece with screw；
Compressed spring is placed on compressor arm, and compressor arm is placed in the through-hole of compact heap.Before detection starts, the locking screw to zero piece is unclamped
Nail, zero piece is gone to can cover the micrometer head measuring staff of the digital display on reference block hole after locking to zero piece of lock-screw, rotate number
Aobvious micrometer head, makes its measuring staff gentle touchdown to zero piece of plane, digital display micrometer head is reset, then by the measurement of digital display micrometer head
Bar is retracted and is unclamped and will replace to zero piece to zero piece of lock-screw, and making to odd-job for digital display micrometer head is completed；Adjustment branch
The height for supportting platform keeps the movable stylus of tested radian table consistent with the measuring staff centre-height of digital display micrometer head；By tested radian table
It is placed in supporting table, adjusts tested radian table front-rear position, make the survey of the movable stylus alignment digital display micrometer head of tested radian table
Bar center compresses tested radian table with compressor arm, is close to two fixed styluses of tested radian table with the datum level of reference block；
Digital display micrometer head is rotated, its measuring rod is contacted and compresses the movable stylus of tested radian table, reads different location digital display respectively
Numerical value on micrometer head and tested radian table handles the error of indication that can be obtained by tested radian table by data operation.
The beneficial effects of the invention are as follows provide a kind of calibration instrument for calibrating the radian table error of indication.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the application overall plan main view of the embodiment of the present invention.
Fig. 2 is the D-D top view of Fig. 1.
Specific embodiment
In Fig. 1, compact heap 8, supporting table 11, reference block 2 are locked with screw-nut on bottom plate 3；Support leg 7 locks in bottom plate
On 3 screw hole, bottom plate 3 is maked somebody a mere figurehead, facilitates the height of adjustment supporting table 11；Digital display micrometer head 1 is installed on the mounting hole of reference block 2
It is interior and fixed with holding screw 9, zero piece 10 is installed on reference block 2 with screw；Compressed spring 6 is placed on compressor arm 5, is compressed
Bar 5 is through in the through-hole of compact heap 8.It before detection starts, unclamps to zero piece 10 of lock-screw, zero piece 10 is gone to and can be covered
The lock-screw to zero piece 10 is locked behind measuring staff hole on reference block 2, is rotated digital display micrometer head 1, is made its measuring staff gentle touchdown pair
Zero piece 10 of plane resets digital display micrometer head 1, then retracts the measuring rod of digital display micrometer head 1 and unclamps to zero piece 10
Lock-screw will replace zero piece 10, complete making to odd-job for digital display micrometer head 1；Adjust supporting table 11 height, make by
The movable stylus for surveying radian table 4 is consistent with the measuring staff centre-height of digital display micrometer head 1, and tested radian table 4 is placed in supporting table 11
On；In Fig. 2, tested 4 front-rear position of radian table is adjusted, makes the measuring staff of the movable stylus alignment digital display micrometer head 1 of tested radian table 4
Center compresses tested radian table 4 with compressor arm 5, keeps the datum level of two fixed styluses and reference block 2 of tested radian table 4 tight
Patch；Digital display micrometer head 1 is rotated, its measuring rod is contacted and compresses the movable stylus of tested radian table 4, read different location respectively
Numerical value on digital display micrometer head 1 and tested radian table 4 handles the indicating value that can be obtained by tested radian table 4 by data operation
Error.
