Abstract
The utility model discloses a measuring tool for accurately measuring the diameter of an inner bore annular groove, which comprises a fixed measuring jaw, a movable measuring jaw and a standard sliding caliper. The measuring tool achieves the purpose of measuring the diameter of the inner bore annular groove with a groove depth less than or equal to 300 mm and a groove width more than or equal to 1.2 mm, and overcomes the problems in the prior art, such as poor measurement accuracy and difficult measurement. The measuring tool is convenient to use, improves the measurement accuracy, has a simple structure, and is low in cost.
Description
Technical field
The utility model relates to a kind of measurer of measuring endoporus ring groove diameter dimension, particularly a kind of measurer of accurate measurement endoporus ring groove diameter dimension.
Background technology
For some engineering goods, the measurement of endoporus ring groove diameter dimension does not all have the diameter measurement of the higher endoporus ring groove of a kind of measurer of standard, particularly some seal grooves, the accuracy requirement of locating slot equal diameter more difficult always.Generally all use common internal calliper to measure the diameter dimension of endoporus ring groove, though this survey instrument is easy to use, its measuring accuracy is not high, has the bigger situation of measuring error, and this makes product quality be difficult to obtain assurance.
The utility model content
The purpose of this utility model is to provide a kind of measurer of accurate measurement endoporus ring groove diameter dimension, can realize measuring groove width 〉=1mm, the measurement of the endoporus ring groove diameter dimension of groove depth≤6mm, measuring accuracy can reach 0.02mm, to overcome the existing low defective of survey instrument measuring accuracy.
The utility model is to constitute like this, and it comprises fixedly measuring jaw 1, movable measuring jaw 2 and standard vernier caliper scale 3.Fixedly measuring jaw 1 is integral structures with standard vernier caliper scale 3, and movable measuring jaw 2 and standard vernier caliper scale 3 are fixed by rivet.Movable measuring jaw 1 is located by scale bar with standard vernier caliper scale 3 and is moved, and can lock by the screw on the standard vernier caliper scale 3.According to concrete operating position, this measurer available standards vernier caliper is changed a social system and is got, fixedly measuring jaw by combination mill processing criterion vernier caliper and movable measuring jaw are to fixed value, can obtain accurately to measure groove width 〉=1mm, the measurer of the endoporus ring groove diameter dimension of groove depth≤6mm, its measuring accuracy can reach 0.02mm.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model measurer.
Embodiment
Fixedly measuring jaw 1 is integral structures with standard vernier caliper scale 3, and movable measuring jaw 2 and standard vernier caliper scale 3 are fixed by rivet.This measurer available standards vernier caliper is changed a social system and is got, fixedly measuring jaw by combination mill processing criterion vernier caliper and movable measuring jaw are to fixed value, can obtain accurately measuring groove width 〉=1mm, the measurer of the endoporus ring groove diameter dimension of groove depth≤6mm, its measuring accuracy can reach 0.02mm.
