Straight-bar；The other end of two horizon bars is flexibly connected in the horizontal direction, and two vertical rods are oppositely arranged.
Further, described fixing gauge head is fixed on inside the vertical rod of fixed ruler frame by trip bolt.
Further, described dial gauge is fixed on inside the vertical rod of slip chi frame by trip bolt.
Further, described fixing gauge head and the centrage of dial gauge are on same straight line.
Further, being provided with groove on the horizon bar of fixed ruler frame, the horizon bar of slip chi frame is embedded in this groove, and two
Person is fixed by regulation screw.
Instrument described in utilization is to method through measuring in workpiece, as follows:
The previously fabricated ring gauge identical with part internal diameter size to be measured of step 1., measures the true of ring gauge size with precision instrument
Value；
Fixing gauge head is fixed on fixed ruler frame by step 2., is fixed on by dial gauge on slip chi frame；
Step 4 regulates fixed ruler frame and the connector of slip chi frame, in making the ring gauge in fixing gauge head and dial gauge gauge head and step 1
Contacts side surfaces；Tighten connector, fixing slip chi frame and the position of fixed ruler frame, then dial gauge pointer is made zero；
Step 5 uses this instrument to measure part internal diameter to be measured, and now the indicated value on dial gauge is part to be measured relative to ring gauge
Deviation value, thus can calculate the actual value of workpiece size.
