Abstract
The utility model relates to a convenient-use detection go-stop gauge for inner diameter spot check on circular pipes. The detection go-stop gauge mainly comprises a go-stop gauge board body composed of a lower limit go gauge segment and an upper limit stop gauge segment connected with the lower limit go gauge segment, wherein one side of the go-stop gauge board body is in the straight-edge arc shape, a connection portion of the lower limit go gauge segment and the upper limit stop gauge segment at the other side is a step, width of the step is a permitted maximum tolerance value between the lower limit go gauge segment and the upper limit stop gauge segment, the edge of each segment is in the arc shape, and two sides of the go-stop gauge board body are in the same arc shape. The detection go-stop gauge has advantages of convenient and fast detection, greatly-improved detection speed, easy enforcement and simple structure during detection or spot check on large batches of steel pipes while detection precision requirements can be satisfied.
Description
Technical field
The utility model relates to a kind of pick-up unit, specifically belongs to a kind of convenience for the detection go-no go gauge of round tube inside diameter sampling observation.
Background technology
In the production of cold-bent pipe, the internal diameter size precision of its product is to judge a whether qualified key factor of product.Just at present, the most frequently used inner diameter measurement instrument is to adopt vernier caliper to detect.The deficiency of its existence is: in the product testing process of steel pipe in enormous quantities, because vernier caliper detects round tube inside diameter one by one, need ninety-nine times out of a hundred to adjust, with the accuracy that guarantees to detect, therefore detection speed is reduced greatly, pick up speed detects a little, and the precision that just may detect is difficult to guarantee, and uses inconvenient.
After testing, Chinese patent open (bulletin) number is 202133361 document, and it is disclosed is for the detection in aperture, to adopt the go-no go gauge of cylindrical shape.The deficiency of its existence is to weigh very much, is inconvenient to use.
Utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, provide a kind of in large batch of steel pipe detection or sampling observation, meeting under the condition of accuracy requirement, easy to detect, quick, improve the convenience of detection speed for the detection go-no go gauge of round tube inside diameter sampling observation.
Realize the technical measures of above-mentioned purpose:
Convenience is for a detection go-no go gauge for round tube inside diameter sampling observation, and it is: it mainly forms go-no go gauge plate body by lower limit drift section, the upper limit no-go gage section that is connected with lower limit drift section; The shape of go-no go gauge plate body a: side is straight flange circular arc, opposite side is step in lower limit drift section and upper limit no-go gage section joint, the width of step is the permission maximum allowance value between lower limit drift section and upper limit no-go gage section, and the limit of each section is circular-arc; The arc of the both sides of go-no go gauge plate body is identical.
It is characterized in that: the upper limit no-go gage section at go-no go gauge plate body is provided with hand-held orifice ring.
Feature of the present utility model is: during large batch of steel pipe is detected or inspected by random samples, meeting under the condition of accuracy requirement, easy to detect, quick, greatly improve detection speed, and easily implement, simple in structure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left TV structure schematic diagram of Fig. 1;
In figure: 1-lower limit drift section, 2-upper limit no-go gage section, 3-go-no go gauge plate body, 4-step, 5-hand-held orifice ring.
Embodiment
Below in conjunction with accompanying drawing, be described further:
Convenience is for a detection go-no go gauge for round tube inside diameter sampling observation, and it is mainly by lower limit drift section 1, adopt whole process or upper limit no-go gage section 2 that plug-in type is connected forms go-no go gauge plate body 3 with lower limit drift section 1; The shape of go-no go gauge plate body 3 a: side is straight flange circular arc, opposite side is step 4 in lower limit drift section 1 with upper limit no-go gage section 2 joints, the width of step 4 is the permission maximum allowance value between lower limit drift section 1 and upper limit no-go gage section 2, and the limit of each section is circular-arc; The arc of the both sides of go-no go gauge plate body 3 is identical.
It should be noted that, the width of lower limit drift section 1 is the minimum pipe value that pipe diameter allows, and the width of upper limit no-go gage section 2 is maximum caliber values that pipe diameter allows; And match with detected pipe diameter.
Stability and hand during for detection are taken convenience, in the upper limit no-go gage section 2 of go-no go gauge plate body, are processed with hand-held orifice ring 5.
During detection, tester's hand handgrip is held orifice ring 5, and lower limit drift section 1 is inserted in steel pipe, and make the straight flange circular arc side of go-no go gauge plate body 3 and its internal diameter tangent, step 4 also can prop up at steel pipe end, illustrates that the internal diameter of this steel pipe, in the bound margin tolerance allowing, is specification product; When step 4 fails to prop up at steel pipe end, and upper limit no-go gage section 2 is entered in steel pipe, illustrate that this pipe diameter is greater than the tolerance upper limit of permission, or lower limit drift section 1 is inserted while not entering in steel pipe, illustrate that this pipe diameter is less than the lower variation of tolerance of permission, is unacceptable product.
Claims (2)
1. convenience, for a detection go-no go gauge for round tube inside diameter sampling observation, is characterized in that: it mainly forms go-no go gauge plate body by lower limit drift section, the upper limit no-go gage section that is connected with lower limit drift section; The shape of go-no go gauge plate body a: side is straight flange circular arc, opposite side is step in lower limit drift section and upper limit no-go gage section joint, the width of step is the permission maximum allowance value between lower limit drift section and upper limit no-go gage section, and the limit of each section is circular-arc; The arc of the both sides of go-no go gauge plate body is identical.
2. a kind of convenience as claimed in claim 1, for the detection go-no go gauge of round tube inside diameter sampling observation, is characterized in that: the upper limit no-go gage section at go-no go gauge plate body is provided with hand hole.
