Description
Technical Field
The utility model relates to a detection instrument field, more specifically says that it relates to a multi-functional logical no-go gage.
Background
Go-no-go gauge, one of gauges, is used as a metric for inspecting products in large quantities. The go-no go gauge is one of measuring tools, and in actual production, large-batch products are troublesome to measure one by adopting measuring tools with scales such as vernier calipers or dial gauges; qualified products have a range of metrics within which they are qualified, so go and no-go gauges are typically used for measurement.
After the pipe fitting is produced and before the pipe fitting leaves a factory, the inner diameter of the pipe orifice needs to be detected, the through end and the stop end of the existing through-stop gauge for detecting the pipe fitting are generally circular, and the through-stop gauge with the circular stop end is adopted, so that when the pipe orifice of the detected pipe fitting is a little smaller than the maximum standard value, the stop end cannot enter the pipe fitting, namely the pipe fitting is judged to be qualified, and the problem of untight detection exists;
in addition, whether the depth of the pipe fitting is qualified or not is generally detected, and the inner diameter of the pipe orifice can be only detected by using the conventional go-no-go gauge; the depth of the pipe fitting can only be detected by other measuring tools, so that the detection efficiency is influenced.
SUMMERY OF THE UTILITY MODEL
To the not enough of prior art existence, the utility model aims to provide a multi-functional logical no-go gage.
In order to achieve the above purpose, the utility model provides a following technical scheme:
a multifunctional go-no go gauge comprises a handle, a go end connected with one end of the handle and a no go end connected with the other end of the handle;
a horizontal tangent plane is arranged at one end part of the through end;
the stop end is in a strip shape, and two ends of the stop end are in arc shapes;
insert the logical end and wait to detect the pipe fitting, and the pipe fitting mouth of pipe is located the horizontal tangent plane of logical end, and the degree of depth of this pipe fitting is qualified, moves the pipe fitting from leading to the end to ending again, twist grip for ending the end along the rotatory round of pipe fitting mouth of pipe, in the unable pipe fitting of inserting of ending, the orificial internal diameter of pipe fitting is qualified promptly.
The utility model discloses further set up: the through end is a cylinder, and the surface of the cylinder is smooth.
The utility model discloses further set up: and the handle is provided with a mounting hole for mounting the go-no go gauge on the detection equipment.

Detailed Description
The embodiment of the multi-functional go-no-go gauge of the present invention will be further described in detail with reference to fig. 1 to 3.
A multifunctional go-no go gauge comprises a handle 1, a go end 2 connected with one end of the handle 1 and a no go end 3 connected with the other end of the handle 1;
a horizontal tangent plane 21 is arranged at one end part of the through end 2;
when the through end 2 can smoothly enter the pipe fitting, namely the inner diameter of the pipe fitting is larger than the minimum standard value, and simultaneously, after the through end 2 falls into the pipe fitting, whether the pipe orifice of the pipe fitting is in the range of the horizontal tangent plane 21 or not is judged, if the pipe orifice is lower than the horizontal tangent plane 21, the depth of the pipe fitting is smaller than the minimum depth value, and if the pipe orifice is higher than the horizontal tangent plane 21, the depth of the pipe fitting is larger than the maximum depth; this go-no-go gage can be used for detecting whether the degree of depth of pipe fitting is in the scope of degree of depth standard value simultaneously promptly, can improve the efficiency that the pipe fitting detected.
The stop end 3 is in a strip shape, and two ends of the stop end are in arc shapes; the circular end stop 3 is to cut off two sides of the circle, the circular arcs on the other two sides of the circle are reserved to form the strip-shaped end stop 3, the end stop 3 is enabled to rotate on the pipe orifice of the pipe fitting by rotating the handle 1, the end stop 3 can detect the pipe fitting more omnidirectionally, when a certain part of inner diameter on the pipe orifice of the pipe fitting is larger than a maximum standard value, the end stop 3 falls into the pipe fitting, and therefore unqualified pipe fittings are detected; the circular end stop 3 can be prevented from directly detecting unqualified pipe fittings into qualified products because the inner diameter of a certain part of the circular end stop 3 is smaller than the maximum standard value and part of the inner diameter is larger than the maximum standard value; the go-no go gauge can improve detection precision.
Wherein lead to end 2 and be the cylinder, and the surface of cylinder is smooth for lead to end 2 can get into qualified pipe fitting smoothly in, avoid leading to end 2 just the surface not smooth and the inspection error that arouses.
The handle 1 is provided with a mounting hole 11 for mounting the go-no go gauge on the detection equipment, and the go-no go gauge is applied to the detection equipment, so that the detection speed is increased, and the production efficiency is improved.
It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
