This utility model is by the following technical solutions:
Measure the instrument of workpiece diameter, meet workpiece for measurement size including a fixed ruler frame, slip chi frame and one public
The ring gauge of difference, arranges a fixing gauge head on described fixed ruler frame, arranges a percentage on described slip chi frame
Table, described dial gauge moves back and forth along the direction at fixing gauge head place under the driving of slip chi frame.
Further, described fixed ruler frame, slip chi frame the most all include a horizon bar and with horizon bar one end phase
Vertical rod even；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
In, both are 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 ring gauge size with precision instrument
Actual 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, makes in fixing gauge head and dial gauge gauge head and step 1
Ring gauge medial surface contacts；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 to be part to be measured relative for the indicated value on dial gauge
In the deviation value of ring gauge, the actual value of workpiece size thus can be calculated.
The beneficial effects of the utility model are as follows:
This measuring method uses comparative measurement method, first a previously fabricated ring gauge meeting part internal diameter size tolerance, uses
The actual value of ring gauge size measured by precision instrument, proofreads the zero-bit of dial gauge, then dial gauge when measuring on this instrument good before measuring
On indicated value be the workpiece deviation value relative to ring gauge, thus can calculate the actual value of workpiece size.By comparing, can
Judge that processed part is the most qualified.
The measurement error of this instrument is mainly by caused by dial gauge and master ring, owing to the error of master ring obtains
Revising, therefore, the certainty of measurement of this instrument is identical with dial gauge.
Accompanying drawing explanation
In order to become apparent from, the technical scheme of this utility model embodiment is described effectively, use required in embodiment
Accompanying drawing be briefly described, it is implicit that, below describe in accompanying drawing be only embodiments more of the present utility model, right

In figure: 1 fixes gauge head, 2 trip bolts, 3 fixed ruler framves, 4 grooves, 5 regulation screws, 6 slip chi framves, 7 fastening spiral shells
Nail, 8 dial gauge gauge heads, 9 dial gauges.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in detail:
Fig. 1 is sleeve part, and wherein the large diameter hole degree of depth of part is less, uses general inner diameter gauge to measure the most not side
Just.To this end, disclose a kind of instrument measuring internal diameter, concrete structure is as follows:
As in figure 2 it is shown, measure the instrument of workpiece diameter, meet including a fixed ruler frame 3, slip chi frame 6 and one and treat
Survey the ring gauge of workpiece size tolerance, described fixed ruler frame 3 arranges a fixing gauge head 1, at described slip chi frame 6
On a dial gauge 9 is set, dial gauge 9 moves back and forth along the direction at fixing gauge head place under the driving of slip chi frame 3；Sliding
Dynamic chi frame 3 can move back and forth relative to fixed ruler frame 3.
Further, fixed ruler frame 3, slip chi frame 6 each all include a horizon bar and are connected with horizon bar one end
Vertical rod；The other end of two horizon bars is flexibly connected in the horizontal direction, and two vertical rods are oppositely arranged；At fixed ruler frame 3
Being provided with groove 4 on horizon bar, the horizon bar of slip chi frame 6 is embedded in this groove, and both are fixed by regulation screw 5；When
When needing mobile dial gauge 9, unclamp regulation screw 5, mobile slip chi frame 6.
Further, fixing gauge head 1 is fixed on inside the vertical rod of fixed ruler frame 3 by trip bolt 2, surveys with dial gauge
8 relative.
