Abstract
The utility model discloses an interior external diameter measuring tool, including support no. 1 and support no. 2, support no. 1 and two swing joint on the support, support no. 1 is gone up has the measuring stick along length direction movable mounting, support no. 2 is gone up has the percentage table along length direction movable mounting, measuring stick and percentage table are located same level straight line, the utility model discloses an interior external diameter measuring tool simple manufacture, it is with low costs, convenient to use, measurement accuracy is high, does not have the people for the elasticity degree error of feeling.
Description
Technical field
The utility model relates to product fields of measurement, particularly a kind of instrument measuring the internal-and external diameter of disk or circle annular workpieces.
Background technology
In tire-mold, disk, annulus base part are a lot, and diameter is comparatively large, so need large-scale survey instrument in process, as outside micrometer, micrometer inside caliper, vernier caliper etc.These metering outfits are expensive, and need prevent colliding with when using.Be circular as shape and overlap pressed on ring in the tire-mold that internal diameter is larger, when using micrometer inside caliper to measure, need the concrete size of overlapping pressed on ring internal diameter in basis, adjustment milscale length bar is to Len req, then gauger swings back and forth in a circumferential direction, according to the tightness of microdrum to determine its internal diameter size reading.Can error be there is to a certain extent due to the feel difference of gauger in this measuring method.
And micrometer inside caliper and outside micrometer can only the internal diameter of measurement products or external diameters, cannot measure internal diameter and external diameter, add use cost simultaneously, and operation inconvenience.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of internal-and external diameter survey instrument, reduces costs to reach, and improves the object of measuring accuracy.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of internal-and external diameter survey instrument, comprise support one and support two, described support one and support two are flexibly connected, described support one is movably installed with sounding rod along its length, described support two is movably installed with dial gauge along its length, and described sounding rod and dial gauge are positioned on same level straight line.In use, regulate between sounding rod and dial gauge also fixing to suitable position according to product size, the fixed position of sounding rod can be regulated during measurement to finely tune, utilize the measuring head of sounding rod and dial gauge gauge head to prop up external diameter or the internal diameter two ends of product respectively, carry out survey measurements.
Preferably, described support one is connected by guide runner with support two, can regulate the relative distance of support one and support two, and cooperation between the two adopts bedding-in mode, and gap is little; And fixedly tightened, for coarse adjustment by screw one.
In further technical scheme, the measuring head of described sounding rod and the gauge head of dial gauge are oppositely installed along same straight line, for measuring internal diameter.
In further technical scheme, the measuring head of described sounding rod and the gauge head of dial gauge are mounted opposite along same straight line, for measuring external diameter.
In such scheme, described sounding rod and dial gauge are arranged on support one and support two respectively by screw two and screw three, for fine setting.
By technique scheme, need this instrument to be placed on when the internal-and external diameter survey instrument that the utility model provides is measured to need in the standard size of measuring workpieces, the pointer of adjustment dial gauge is in zero-bit; Be placed on workpiece by the survey instrument proofreaded, the measuring head of sounding rod contacts external diameter or internal diameter with the gauge head of dial gauge, different according to size, and beat of pointer position is different, and the scale indicated by pointer is workpiece and departs from standard-sized deviation.

Wherein, 1, support one; 2, support two; 3, guide runner; 4, screw one; 5, screw two; 6, screw three; 7, sounding rod; 8, dial gauge; 9, measuring head; 10, gauge head.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
The utility model provides a kind of internal-and external diameter survey instrument, and cost is low, easy to use, and measuring accuracy is high, can measure internal diameter and external diameter.
Internal-and external diameter survey instrument as depicted in figs. 1 and 2, comprise support 1 and support 22, support 1 is connected by guide runner 3 with support 22, can regulate the relative distance of support 1 and support 22, and is fixedly tightened by screw 1, carries out coarse adjustment during measurement.Support 1 is movably installed with sounding rod 7 along its length, support 22 is movably installed with dial gauge 8 along its length, sounding rod 7 and dial gauge 8 are positioned on same level straight line.Sounding rod 7 and dial gauge 8 are arranged on support 1 and support 22 respectively by screw 25 and screw 36, and the mounting distance of sounding rod 7 is finely tuned by screw 25.
It should be noted that, the installation site of sounding rod 7 and dial gauge 8 can be exchanged, and support 1 and support 22 just play fixed support effect.
As shown in Figure 1, when measuring internal diameter, the measuring head 9 of sounding rod 7 and the gauge head 10 of dial gauge 8 are oppositely installed along same straight line, and being placed on by this instrument needs in the standard size of measuring workpieces, and the pointer of adjustment dial gauge 8 is in zero-bit; Be placed on workpiece by the survey instrument proofreaded, the measuring head 9 of sounding rod 7 contacts workpiece diameter with the gauge head 10 of dial gauge 8, different according to size, and beat of pointer position is different, and the scale indicated by pointer is workpiece and departs from standard-sized deviation.
As shown in Figure 2, when measuring external diameter, the measuring head 9 of sounding rod 7 and the gauge head 10 of dial gauge 8 are mounted opposite along same straight line, and being placed on by this instrument needs in the standard size of measuring workpieces, and the pointer of adjustment dial gauge 8 is in zero-bit; Be placed on workpiece by the survey instrument proofreaded, the measuring head 9 of sounding rod 7 contacts workpiece external diameter with the gauge head 10 of dial gauge 8, different according to size, and beat of pointer position is different, and the scale indicated by pointer is workpiece and departs from standard-sized deviation.
The internal-and external diameter survey instrument measuring accuracy that the utility model provides is high, there is not artificial feel tightness error; Cost is low, easy to use; Adopt bedding-in mode between support 1 and support 22, gap is little, good rigidly; Both can carry out inner diameter measurement, can outside diameter measuring be carried out again.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
