The fit tolerance of clearance fit described above is g6/H7.Above-mentioned tolerance fit enable cooperation between axis and hole
Sliding, rotation, but cannot shake.
In addition, the measurement method using the device is summarized as follows：
A. when volume production measures
It need to only be checked quickly through property with using detection shank 3 to do, detect the test side of shank 3 according to sheet metal nut
Position of related features carry out conversion design.
B. when development phase
Measuring block 5 and locking nut test pin 6 are used cooperatively to detect the concrete numerical value of 7 position degree of sheet metal nut, so as to
Bristle with anger and shows rectification welding fixture.
In use, need to only need 6 precession of locking nut test pin on the sheet metal nut 7 detected, measuring block 5 is packed into inspection
It surveys on shank 3, locking nut test pin 6 is arrived on detection shank 3 top, then motionless with the support locking detection shank 3 of locking pin 4.It pushes away
Dynamic measuring block 5 stops until the face that measurement column 52 encounters sheet metal component, and the measurement column 52 on measuring block 5 is accurately measured using clearance gauge
The distance between locking nut test pin 6, finally converses the deviation of 7 position degree of sheet metal nut.
Since measuring block 5 can arbitrarily rotate on detection shank 3, so all directions of sheet metal nut 7 to be detected
Position degree deviation all can measure.
The design focal point of the present apparatus is：
1, detection shank 3 and guide sleeves 2 belong to clearance fit (g6/H7 fit tolerances), opposite sliding and can rotate but not
There can be shaking；
2, measuring block 5 belongs to clearance fit (g6/H7 fit tolerances) with detection shank 3, opposite sliding and can rotate but not
There can be shaking；
3,6 measurement end of locking nut test pin must high-precision processing and fabricating.
By above-mentioned measuring device, the position of all directions of the nut on sheet metal component can be easily and accurately measured
Degree, and measurement error can be controlled in 0.1mm, improve homework precision.
It will be apparent to those skilled in the art that technical solution that can be as described above and design, make various other
Corresponding change and deformation, and all these changes and deformation should all belong to the protection of the utility model claims
Within the scope of.
