Description

A kind of internal diameter measuring instrument
Technical field
The utility model belongs to survey instrument technical field, particularly relates to a kind of internal diameter measuring instrument.
Background technology
Measure the internal diameter of some products, part, and meet the requirements of precision, conventional survey instrument is vernier caliper.Vernier caliper measurement internal diameter Problems existing is that the inner measuring jaw of vernier caliper is shorter, and a lot of product, inside parts are comparatively dark or inside surface irregular, and the inner measuring jaw of vernier caliper accurately can not arrive measuring point, causes measuring.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned drawback, a kind of internal diameter measuring instrument is provided, realizing the technical scheme that originally practical object is taked is: a kind of internal diameter measuring instrument, comprise left measuring claw and right measuring claw, it is characterized in that: a circular arc main scale is fixed in the upper end of described left measuring claw, circular arc main scale is provided with graduated scale, it is a kind of vernier caliper that can take measurement of an angle, circular arc main scale is set with vernier scale, vernier scale can slide on circular arc main scale, and right measuring claw is fixed on vernier scale.Described circular arc main scale is provided with main scale jack, and left measuring claw is provided with left measuring claw plug, and vernier scale is provided with vernier scale jack, and right measuring claw is provided with right measuring claw plug, utilizes plug and jack to be fixed together respectively.The insertion of left measuring claw and right measuring claw can be facilitated or extract.
The utility model structure is simple, with low cost, easy to use, measuring accuracy is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1, left measuring claw, 2, right measuring claw, 3, circular arc main scale, 4, graduated scale, 5, vernier scale, 6, main scale jack, 7, left measuring claw plug, 8, vernier scale jack, 9, right measuring claw plug, O is the center of circle, and OA and OB is radius, and Q is the angle of OA and OB.
Embodiment
With reference to accompanying drawing, a kind of internal diameter measuring instrument, comprise left measuring claw 1 and right measuring claw 2, it is characterized in that: a circular arc main scale 3 is fixed in the upper end of described left measuring claw 1, circular arc main scale 3 is provided with graduated scale 4, is a kind of vernier caliper that can take measurement of an angle, circular arc main scale 3 is set with vernier scale 5, vernier scale 5 can slide on circular arc main scale 3, and right measuring claw 2 is fixed on vernier scale 5.Described circular arc main scale is provided with main scale jack 6, and left measuring claw 1 is provided with left measuring claw plug 7, and vernier scale 5 is provided with vernier scale jack 8, and right measuring claw 2 is provided with right measuring claw plug 9, utilizes plug and jack to be fixed together respectively.The insertion of left measuring claw and right measuring claw can be facilitated or extract.
During use, measuring claw 1 and right measuring claw 2 are probeed into inside parts and measures.Circular arc main scale 3 reads OA and OB angle Q, is definite value because OA and OB is radius, utilizes counter to obtain distance between A-B according to formula.
