Shallow endoporus described in refers exclusively to the actual height obstructed endoporus less than 5mm or stepped hole.Gauge head is the primary clustering of dial bore gage,
It is used for the numerical value carrying out determining according to Centigrade scale, carries out positioning bar distance and adjust, finally determine dial gauge reading (pointer zero setting),
During measurement by contact with endoporus drive dial indicator head pointer swing, determine the actual size of endoporus.
Existing inside callipers and band table inside callipers, the former need to possess the operator quite measuring experience, be at best able to reach
The certainty of measurement of 0.01mm, but cannot be carried out measurement higher than this precision and study and judge, though the latter can carry out reading by dial gauge, but
Its two point form metering system locating accuracy is relatively low.Therefore, the defect of prior art is: (1) scope of application limitation is big:
In the course of processing, machining status cannot measure monitoring by real-time accurate, and the whole course of processing is in blind machining state, and inside plain calipers is measured
Completely determining that result is measured in side with feel, veteran master craftsman can control about certainty of measurement 0.01mm, to 0.01mm with
Interior hole measuring is without absolute belief；(2) measurement error poor accuracy: refer to utilize special to table attachment frame both sides to table attachment
The band cambered surface that changes the outfit to block, form feeler gauge structure, study and judge hole size with feel, experience, error is relatively big, and cambered surface is to block
Radian size measurement effect can be impacted, need again clamping centering can carry out secondary operations after measurement, cause and add
The work cycle is long, and percent defective is high.
Utility model content
The purpose of this utility model is the drawbacks described above overcoming internal diameter measuring instrument to exist, it is proposed that a kind of shallow bore inner diameter measuring instrument,

Pawl I, measuring claw II and measuring claw III, it is ensured that the tram of measuring claw group during measurement；The slide rail arranged on support, it is fixed to make
Position pawl size can be adjusted by workpiece size requirement, substantially covers the measurement scope of the workpiece that existing operation is processed, as
There is a need to, achieve the goal also by the slide rail length changed on the right side of support I.
This utility model is to use following technical scheme to realize: a kind of shallow bore inner diameter measuring instrument, including dial bore gage,
Being provided with measurement axis bottom dial bore gage, dial bore gage is fixedly arranged in the middle of support, and support is divided into support I He with slide rail
It is oppositely arranged with measuring claw core shaft support II, support I and support II, slide rail is fixed with locating detent, on measuring claw mandrel
Be fastened with measuring claw I, measuring claw II and measuring claw III by compression spring, measuring claw II be positioned at measuring claw I and measuring claw III it
Between, the other end of measuring claw II is connected with measurement axis；Measuring claw I, measuring claw II, measuring claw III and locating detent are bottom
Eversion type structure.
Further, locating detent is positioned along the slip of slide rail level by trip bolt.
Further, measuring claw I and measuring claw III are by the pretightning force of compression spring and measuring claw II compact siro spinning technology.
Further, measuring claw I, measuring claw II contact hole wall diverse location respectively with measuring claw III.
Further, support I and support II are fixed with dial bore gage by fastening bolt.
Further, measuring claw I, measuring claw II and measuring claw III rotate rotating around measuring claw mandrel.
The beneficial effects of the utility model are:
(1) shallow bore inner diameter measuring instrument described in the utility model, by designing and producing special measuring jaw, eliminates dial bore gage
The problem that the shallow endoporus of inter process that measuring head structure problem causes accurately measures difficulty；
(2) shallow bore inner diameter measuring instrument described in the utility model, the adjustable locating detent of design can meet a range of
Hole measuring；
(3) shallow bore inner diameter measuring instrument described in the utility model, the free-standing compression spring installed additional, make measuring claw group respectively
Measuring jaw, locating detent are close on the gauge head of dial gauge, positioning sleeve all the time, it is therefore prevented that during gauge head press-in workpiece, backwards rotation occurs
Phenomenon occurs.

Detailed description of the invention
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, shallow bore inner diameter measuring instrument described in the utility model, including locating detent 8, trip bolt 13,
Support group, fastening bolt 14, measuring claw mandrel 6, compression spring 9, measuring claw group and dial bore gage 1.This utility model
Measuring claw group possesses the position stability of dial gauge gauge head, overcomes again the structure problem of dial gauge side head, as used amesdial head,
Can realize accurately measuring.This utility model includes dial bore gage 1, is provided with measurement axis 2, internal diameter bottom dial bore gage 1
Dial gauge 1 is fixedly arranged in the middle of support, and support is divided into the support I 5 with slide rail 4 and the support II 7 with measuring claw mandrel 6,
Support I 5 and support II 7 are oppositely arranged, and slide rail 4 is fixed with locating detent 8, tight by compression spring 9 on measuring claw mandrel 6
Intrinsic gauging pawl I 10, measuring claw II 11 and measuring claw III 12, measuring claw II 11 be positioned at measuring claw I 10 and measuring claw III 12 it
Between, the other end of measuring claw II 11 is connected with measurement axis 2；Measuring claw I 10, measuring claw II 11, measuring claw III 12 and location
Pawl 8 is bottom eversion type structure 3.
Wherein, locating detent 8 is used for carrying out size adjusting, location.Coordinate the measurement determining workpiece with Centigrade scale according to technological requirement
Numerical value.
Trip bolt 13, after being adjusted in place when locating detent 8, is used for fixing locating detent 8 so that it is have changeless position.
Support group is carrying measuring jaw mechanism all components the assembly connected in dial bore gage 1, and locating detent 8 can be along support I 5
Slide rail 4 carry out slide location.
Fastening bolt 14 is for by support group and the fixing adnexa (two pieces) of dial bore gage 1.Dial bore gage 1 refers to use
In the special measuring tool of hole measuring, it is currently inter process and carries out the survey tool that hole measuring is more accurate.
