Abstract
The utility model relates to a bore dial indicator check -up, and use the ring gage is used in big hole calibration of high -usage, including the ring gage body, ring gage body up end leaves has a standard circle groove, the terminal surface is opened down has the 2nd standard circle groove and a standard circle groove central line and the 2nd standard circle groove central line coincidence, a standard circle groove diameter is lighter than the 2nd standard circle groove diameter. The advantage: ring gage is used in big hole calibration not only uses the high -usage, and the bore dial indicator of being convenient for moreover proofreads and detects.
Description
Technical field
The utility model is related to a kind of dial bore gage that is used for and verifies, and using the high big endoporus calibration ring of utilization rate
Rule, belong to inside-diameter measuring tool and manufacture field.
Background technology
Existing ring standard gauge is made of metal, and is made to annular.Endoporus is through grinding, size is through accurate instrument
Measured value is provided, as standard size after device detection.But existing standard ring gauge, a ring standard gauge can only allow dial bore gage
Verify a kind of standard size, not only utilization rate efficiency is low for such ring standard gauge particularly large scale ring gauge, and increased and make
User uses burden.
Utility model content
Purpose of design: for avoiding the deficiency in background technology, design a kind of dial bore gage that is used for and verify, and using utilization
The high big endoporus calibration ring gauge of rate.
Design: for realizing above-mentioned purpose of design.1st, described ring gauge body upper surface has the first standard circular groove, lower end
Face has the second standard circular groove and the first standard round groove center line is overlapped with the second standard round groove center line, described first standard round
Groove diameter is less than the design of the second standard circular groove diameter, is one of technical characteristic of the present utility model.The purpose of so design exists
In: described ring gauge body upper surface has the first standard circular groove, lower surface has the second standard circular groove and the first standard circular groove in
Heart line is overlapped with the second standard round groove center line, and described first standard circular groove diameter is less than the second standard circular groove diameter, due to one
Individual ring gauge has two standard endoporus, so not only increases the applicability of ring gauge, and is easy to dial bore gage check and correction detection.
2nd, described first standard circular groove bottom land has lightening hole and lightening hole side and the first standard circular groove insertion, opposite side and the second mark
Director circle groove insertion, the diameter of described lightening hole is less than the design of the first standard circular groove diameter, is technical characteristic of the present utility model
Two.The purpose of so design is: lightening hole alleviates the weight of ring gauge, consequently facilitating ring gauge upset uses；And lightening hole
Diameter be less than the first standard circular groove diameter, so when dial bore gage is proofreaded by the first standard circular groove it can be avoided that
The detection termination of dial bore gage falls in the second standard circular groove.3rd, described first standard circular groove notch chamfering；Second standard round
The design of groove notch chamfering, is the three of technical characteristic of the present utility model.The purpose of so design is: described first standard round
Groove notch chamfering；Second standard circular groove notch chamfering, the inspection of dial bore gage so when dial bore gage enters ring gauge check and correction
Survey termination to be damaged by circular groove notch.
Technical scheme: a kind of big endoporus calibration ring gauge, including ring gauge body, described ring gauge body upper surface has first
Standard circular groove, lower surface have the second standard circular groove and the first standard round groove center line is overlapped with the second standard round groove center line,
Described first standard circular groove diameter is less than the second standard circular groove diameter.
, compared with background technology, big endoporus calibration ring gauge is not only high using utilization rate for the utility model, and in being easy to
Footpath dial gauge check and correction detection.
Brief description
Fig. 1 is the perspective view of big endoporus calibration ring gauge.
Fig. 2 is the cross section structure diagram of big endoporus calibration ring gauge.
Specific embodiment
Embodiment 1: referring to the drawings 1 or Fig. 2.A kind of big endoporus calibration ring gauge, including ring gauge body 1, described ring gauge is originally
Body 1 upper surface has the first standard circular groove 2, lower surface has the second standard circular groove 3 and the first standard circular groove 2 center line and second
Standard circular groove 3 center line overlaps, and described first standard circular groove 2 diameter is less than the second standard circular groove 3 diameter；Described ring gauge body 1
Upper and lower end face is horizontal plane.Described first standard circular groove 2 bottom land has lightening hole 4 and lightening hole 4 side and the first standard round
Groove 2 insertion, opposite side and the second standard circular groove 3 insertion, the diameter of described lightening hole 4 is less than the first standard circular groove 2 diameter.Described
Lightening hole 4 upper port and the equal rounding of lower port, so it can be avoided that use during lightening hole 4 hole wall scratch hand.Described
First standard circular groove 2 notch chamfering；Second standard circular groove 3 notch chamfering.A diameter of 120mm of described first standard circular groove 2.
It is to be understood that: the detailed word although above-described embodiment is contrasted to mentality of designing of the present utility model
Description, but these word descriptions, simply describe to the simple text of the utility model mentality of designing, rather than new to this practicality
The restriction of type mentality of designing, any combination, increase or modification without departing from the utility model mentality of designing, each fall within this practicality new
In the protection domain of type.
