Description
Technical field
This utility model belongs to shift fork axle fields of measurement, is specifically related to a kind of shift fork axle axial dimension aided measurement device.
Background technology
Existing shift fork axial workpiece, needs to ensure the distance of arc groove centre-to-centre spacing end face, for this distance, common measuring method
It is to utilize cylinder length bar, V-block and digital display height gauge to measure on shift fork axle at the bottom of arc groove, to arrive end face distance.Process because of actual
Gap is there is between shift fork axle circular arc and measurement length bar, it cannot guarantee that perfectly level when placing in arc groove, can only be by anti-
Multiple fine setting guarantees that difference in height measured again by length bar after being perpendicular to shift fork axle, time-consuming 2 minutes of each workpiece calibration process average, and can not
Intuitively obtain the actual deviation value of workpiece.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, it is provided that a kind of shift fork axle axial dimension aided measurement device, surveys improving
While accuracy of measurement, improve detection efficiency.
In order to achieve the above object, this utility model includes the base for fixed standard part, and is used for inserting standard component arc groove
Interior wedge pin, wedge pin offers through hole, and straight pin is fixing in through-holes, and is furnished with digital display 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.
Compared with prior art, device of the present utility model is coordinated with standard component by wedge pin, forms standard size, puts into be measured
During part, 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 carrying
While high measurement accuracy, improve detection efficiency, when especially changing product measurement between the different cultivars of same outer diameter, only need to calculate
Difference difference can measuring after compensating on digital display height gauge in good institute converted products and the axial dimension of this standard component, this is significantly
Shorten and change the product time, improve production efficiency.
Further, wedge pin of the present utility model includes semi-circular base, the plane of semi-circular base has thickness and is gradually increased
Wedge body, constantly can be adjacent to eliminate between length bar and shift fork axle circular arc by the radial component effect of ramp structure in use
Gap, location, effective centering also clamps workpiece, shortens the adjustment time.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further.
Seeing Fig. 1 to Fig. 7, this utility model includes the base 4 for fixed standard part 1, and is used for inserting standard component 1 circle
Wedge pin 2 in arc groove, wedge pin 2 offers through hole, and straight pin 3 is fixing in through-holes, and is furnished with digital display height gauge, tiltedly
Taper 2 includes semi-circular base, and the plane of semi-circular base has the wedge body that thickness is gradually increased, and through hole is opened in wedge pin
One end that 2 thickness are big.
Having a semi-circular groove with the identical circular arc of shift fork axle on standard component 1, the axial dimension of semi-circular groove is the axial of shift fork axle
In dimensional standard poor.
Using method of the present utility model, comprises the following steps:
Step one, fixed cylinder pin 3 in the through hole of wedge pin 2；
Step 2, is measuring standard component inserted base 4 on flat board；
Step 3, after wedge pin 2 is penetrated base 4 insert standard component 1 arc groove in and pass base 4, fix standard component
4；
Step 4, allow the gauge head of digital display height gauge of adapted at standard component 1 end contact, according to dimensional requirement axial on standard component 1
The measured value of standard value by after the dimension compensation of height gauge to standard value and by dial plate to zero；
Step 5, removes wedge pin 2 and standard component 1, inserts part 5 to be measured；
Step 6, in inserting the arc groove of part 5 to be measured and pass base 4, fixes part to be measured after wedge pin 2 is penetrated base 4
5, then the axial end of part 5 to be measured is touched with the gauge head of digital display height gauge, i.e. can be shown that the axial dimension deviation of part 5 to be measured,
The axial dimension of part to be measured is the tolerance indicating value that the axial standard size of standard component adds digital display height gauge.
Seeing Fig. 2, wherein, the reality value at quarter when standard component and base manufacture is that base 4 baseplane is to C cross section for H1+H2, H1
Height reality value at quarter, H2 is the standard component arc groove bottom centre i.e. C cross section theoretical level to standard component axial end.
This utility model can be by first calculating the difference of part to be measured and standard component, then after compensating standard value on digital display height gauge
Measurement obtains part axial dimension to be measured, and through onsite application, initial workpiece is measured within the time can shorten to 1 minute, and the 2nd later
The workpiece calibration average used time, at about 20 seconds, plays the effect simplifying measuring process, has reached target.
