Ruler frame measuring claw measuring surface, ruler frame measuring claw measuring surface are parallel to blade measuring surface.
Further, two opposite sides of the ruler frame measuring jaw free end are equipped with ruler frame measuring claw measuring surface.
Preferably, the ruler frame measuring jaw is n shapes or c shapes.
Further, the left end of the blade is equipped with blade measuring jaw, and blade measuring jaw is mounted on ruler by screw and positioning pin
With, blade measuring surface is arranged on the end face of blade measuring jaw free end.
Preferably, the blade is equipped with scale, and ruler frame is equipped with vernier.
Another preferred, the blade is equipped with static grate ruler and protective film, and ruler frame is equipped with digital display moving grid and display.
The operating procedure of the present invention is as follows：
The ruler frame of two ruler frame measuring jaws is surveyed the same side (A faces) that measuring surface is positioned over two keyway of measured workpiece by step 1,
Mobile blade makes blade measuring surface and measured workpiece Cylindrical Surfaces Contact, writes down numerical value A；
Measured workpiece is rotated 180 ° by step 2, and the ruler frame measuring claw measuring surface of two ruler frame measuring jaws is made to be positioned over tested work
The opposite side (B faces) of two keyway of part, attachable mechanical stage body makes blade measuring surface and measured workpiece Cylindrical Surfaces Contact, writes down numerical value B；
Step 3, numerical value A and the half of the absolute value of numerical value B differences are the opposite cylinder datum axis symmetry of double bond slot
Deviation.
Step 4, in step 1, using digital display calliper measured value A when, press " zero setting " (i.e. " ZERO ") key, then step 3
The half of middle numerical value B absolute values is double bond slot with respect to cylinder datum axis symmetry deviation.
Rational in infrastructure, easy to operate, high certainty of measurement of the invention does not need to accurately measure by auxiliary tool double
Keyway is with respect to cylinder datum axis symmetry deviation.
