Hole, locking screw hole is interior to connect lock-screw；The lower part of auxiliary device is claw, and one is machined on claw and is extended perpendicular to sliding slot
The calibration plane in direction.
A spherical calibration portion is fixed in the calibration plane, at spherical calibration portion and plane contact to be measured, only
There are the highest point of spherical surface and plane contact to be measured, avoids the flatness due to calibration plane inadequate, with plane contact position to be measured
When different, measurement error will cause.
Specific measurement process:
The first standard gauge block is clamped by the measuring claw of slide calliper rule first, activity is surveyed when recording the first standard gauge block of calliper to measure
The indicating value that measuring jaw is directed toward marks a, and compared with the physical length A of the first standard gauge block, obtains the mark of the first standard gauge block of measurement
When standard length, the measured length of slide calliper rule and the error amount a1 of actual length are a-A；The first standard gauge block is unloaded, activity is measured
Pawl remains pointing to the indicating value mark position a when the first standard gauge block of measurement, and the fastening screw of movable measuring claw is tightened, and makes its position
Set locking；Then the detent portion of the utility model auxiliary device is socketed on slide calliper rule blade by sliding slot, and makes auxiliary device
The calibration plane side of claw is opposite with the clamping face side of slide calliper rule activity measuring claw；Sliding assisting apparatus, until auxiliary device card
When spherical calibration portion in pawl calibration plane presses closer the clamping face of slide calliper rule activity measuring claw, by the fastening spiral shell in auxiliary device detent portion
Nail is tightened, and locks auxiliary device in slide calliper rule blade position；At this point, the spherical calibration portion in auxiliary device claw calibration plane is most
Front end is the continued access zero point measured again；Second standard gauge block one end is against the spherical mark in auxiliary device claw calibration plane
Determine in portion, the measuring claw of slide calliper rule clamps the other end of the second standard gauge block, carries out continued access detection, obtains the second standard of calliper to measure
The indicating value that activity measuring claw is directed toward when gauge block marks c, and compared with the physical length B of the second standard gauge block, obtain measurement first,
When the full-length that the second two standard gauge blocks are added, the measured length of slide calliper rule and the error amount c1 of actual length are c-B-A；It unloads
Movable measuring claw, is locked on new continued access dead-center position by lower second standard gauge block again, repeats auxiliary device and standard gauge block
Continued access detection process, indicating value marks error testing at achievable slide calliper rule maximum gauge block scale.
Beneficial effect
The auxiliary device of the utility model can be realized the error testing to wide-range general calipers indicating value mark, detection knot
Fruit is accurate, is operated, can be shown the general calipers of 1000mm or more range by the continued access zero point of auxiliary device and standard gauge block
It is worth the accurate calibrating of mark；Operation can also be operated by continued access zero point is applied in combination standard gauge block, reduces standard gauge block and answers
Use quantity.
