While improving certainty of measurement, improve detection efficiency.
In order to achieve the above object, a kind of shift fork axle axial dimension aided measurement device, including the base for fixed standard part, with
And for inserting the wedge pin in standard component arc groove, wedge pin offering through hole, straight pin is fixing in through-holes, and is furnished with number
Aobvious height gauge.
Described wedge pin includes semi-circular base, and the plane of semi-circular base has the wedge body that thickness is gradually increased.
Described through hole is opened in one end that wedge pin thickness is big.
Having a semi-circular groove with the identical circular arc of shift fork axle on described standard component, the axial size of semi-circular groove is shift fork axle
In axial dimension standard poor.
The using method of a kind of shift fork axle axial dimension aided measurement device, comprises the following steps:
Step one, fixed cylinder pin in the through hole of wedge pin；
Step 2, is measuring standard component inserted base on flat board；
Step 3, in inserting the arc groove of standard component and pass base, fixes standard component after wedge pin is penetrated base；
Step 4, allow the gauge head of digital display height gauge of adapted at standard component end contact, according to dimensional requirement standard axial on standard component
Value measured value by after the dimension compensation of height gauge to standard value and by dial plate to zero；
Step 5, removes wedge pin and standard component, inserts part to be measured；
Step 6, in inserting the arc groove of part to be measured and pass base, fixes part to be measured, then uses number after wedge pin is penetrated base
The gauge head of aobvious height gauge touches the axial end of part to be measured, i.e. can be shown that the axial dimension deviation of part to be measured.
In described step 6, the axial dimension of part to be measured is the deviation indicating value that the axial standard size of standard component adds digital display height gauge.
Compared with prior art, assembly of the invention is coordinated with standard component by wedge pin, forms standard size, when putting into part to be measured,
Digital display height gauge can show the difference of part to be measured and standard component, thus obtains the axial dimension of part to be measured.This device is improving measurement
While precision, improve detection efficiency, when especially changing product measurement between the different cultivars of same outer diameter, only need to calculate added
Difference difference can measuring after compensating on digital display height gauge in chemical product and the axial dimension of this standard component, this is greatly shortened and changes
The product time, improve production efficiency.
The wedge pin of the present invention includes semi-circular base, the plane of semi-circular base has the wedge body that thickness is gradually increased, makes
Used time can constantly be adjacent to eliminate the gap, location between length bar and shift fork axle circular arc by the radial component effect of ramp structure, effectively
Centering also clamps workpiece, shortens the adjustment time.
The method of the present invention is by first calculating the difference of part to be measured and standard component, then compensates survey after standard value on digital display height gauge
Measure part axial dimension to be measured, through onsite application, within the initial workpiece measurement time can shorten to 1 minute, after adjustment, the 2nd
Part later workpiece calibration average used time, at about 20 seconds, plays the effect simplifying measuring process, has reached target.
