Description
Technical field
The invention belongs to be machined fields of measurement, and in particular to a kind of measurement Groove-width check tool.
Background technology
In machine industry, generally by the detection of instrument and meter, the size of workpiece is controlled, it is relatively more normal
Have：Vernier caliper, bevel protractor etc..
And in the processing of precision optical machinery parts, for opening up notch, and the groove width of the notch inside class circular ring structure
When design size precision reaches the design requirement of 0.01mm, conventional detection instrument cannot meet the needs of detection.In order to improve
The accuracy of detection of such groove width is generally detected using three coordinate detection devices., it is necessary to elder generation when being detected using the equipment
Under workpiece is dismantled from lathe, then turn to be detected by three coordinate detection devices, workpiece clamping back and forth seriously affects production
Can, the first inspection time is longer after replacing cutter every time.In addition, the workpiece of positive work in-process can not be also detected, i.e.,：Processing
Size in the process is unable to control.
The content of the invention
It is an object of the invention to provide a kind of measurement Groove-width check tool, to solve existing inspection mentioned above in the background art
The problem of process of measurement equipment detection workpiece groove width is relatively complicated, and detection efficiency is relatively low.
To achieve the above object, the present invention provides following technical solution：A kind of measurement Groove-width check tool including vertical blocks, is surveyed
Measure calibrated bolck and dial gauge, the vertical blocks are followed successively by pedestal, supporting rod and dial gauge fixed plate from down to up, the pedestal and
What dial gauge fixed plate was mutually parallel is arranged at supporting rod both ends of the surface, is offered vertically in the dial gauge fixed plate and dial gauge
The matched mounting hole of mounting rod；
The measurement standard block be rotary structure, middle part, the length at the middle part corresponding with workpiece inner trough structure
Degree is consistent with the maximum material size of groove width to be measured, along structure on the notch of corresponding workpiece inside groove, distinguishes cloth on both sides of the middle
The first support portion and the second support portion equipped with cylindrical structure will be measured by first support portion and the second support portion and marked
Quasi- block frame is arranged on workpiece inside groove corresponding position；
Relative size of the inside groove compared with length in the middle part of measurement standard block is measured by dial gauge, then with middle part length dimension
Computing is carried out for standard, you can obtains groove width actual size.
During using the cubing, measurement standard block is positioned over workpiece inside groove corresponding position so that the first support portion and second
Support part is erected on the notch of inside groove respectively along upper.By adjusting being installed on the dial gauge in vertical blocks so that on dial gauge
The end contact of contact and the second support portion when one side is bonded with inside groove one side in the middle part of measurement standard block, records first number
According to traverse measurement calibrated bolck causes the opposite side at middle part and the opposite side of inside groove to fit, and records second of data, first number
It is the measured value obtained according to the changing value between second of data, the sum of the length dimension and measured value at middle part is groove width
Actual size.
Further, the dial gauge fixed plate one side offers the notch for being through to mounting hole, and the dial gauge is fixed
Plate opposite side is further opened with the clamp screw keyhole to intersect with notch, it is preferred that the notch intersects vertically with clamp screw keyhole.
After dial gauge is installed on dial gauge fixed plate, clamping force is applied to notch by tight fixed bolt, since notch runs through
To mounting hole, so as to one clamping force of dial gauge mounting rod.
Further, due to measurement standard block middle part be with the corresponding rotary structure of inner trough structure, using
Cheng Zhong in order to reduce the overall weight of measurement standard block, can deviate measurement standard block axis certain distance, by middle part milling and go
Except a part, a plane is become.
Compared with prior art, the beneficial effects of the invention are as follows：
（1）It can be measured after checking when participating in the cintest and replacing cutter in the case where not dismantling part status, can effectively prevent from dismantling
After measure it is unqualified and can not again accurate clamping the problem of；
（2）Scene can detect groove width at any time, and obtain its actual dimensional values；
（3）This cubing is the improvement to original measurement means, can improve the efficiency of the work of quality inspection personnel, improves production class
Secondary processing progress and beat.
