Abstract
The utility model provides an airtight double-shoulder instrument for measuring the depth of sealing surfaces in a drill-rod joint, to satisfy the higher and higher requirements for the sealing performance of the drill-rod joint as the oil and natural gas exploitation environment is stricter and stricter. The instrument is characterized in that a spherical metal seal surface is in sealed interference fit with a tapered metal seal surface when internal and external threaded pieces of the drilling-rod joint are cooperated, thereby providing higher sealing performance. However, the sealing surfaces may have errors in precision in the processing process of a numerical-control machine tool, so that the depths of the sealing surfaces need to be measured. After the instrument is used, a positioning rod is positioned close to a port of a to-be-detected workpiece, a measuring sleeve is moved to a proper position and fixed by a locking device, the sealing surfaces are measured via measuring moving contacts, and thus, measurement is rapid and convenient. Different specifications of products can be measured by the instrument due to a measuring slot and a positioning rod groove. The instrument is also simple in structure, easy to replace and convenient to maintain.
Description
Technical field
The utility model belongs to plant equipment testing tool field, is specially the two shoulder drilling rod inner sealing surface depth measurers of a kind of hermetic seal.
Background technology
Along with the more and more harshness of oil, natural gas extraction environment, require also more and more higher to the sealing property of drill pipe sub, therefore develop the two shoulder drilling rod of a kind of Novel air sealing, when its distinguishing feature is exactly the cooperation of drill pipe sub internal and external threads part, adopt being sealed and matched of spherical metal sealing surface and the interference of cone-shape metallic leak-proof face, higher sealing property can be provided.But sealing surface exists trueness error in numerically-controlled machine process, the requirement that does not even reach design objective when serious, therefore must measure the degree of depth of sealing surface, for the data adjustment of machining tool provides information accurately.
Summary of the invention
In order to address the above problem, the utility model proposes the two shoulder drilling rod inner sealing surface depth measurers of a kind of hermetic seal, it can detect the sealing of the two shoulder drilling rod of hermetic seal quickly and easily, and simple in structure, and replaceability is higher, easy to maintenance.
The two shoulder drilling rod inner sealing surface depth measurers of a kind of hermetic seal, its technical scheme is such: it comprises dial gauge, it is characterized in that: it also comprises backstay, sounding rod, described sounding rod runs through measurement sleeve, one end of described sounding rod is connected with described dial gauge, the described sounding rod other end is fastened with measurement moving contact, on described backstay, alongst have positioning rod slot, on described measurement sleeve, alongst have measurement groove, described measurement groove runs through described measurement sleeve along its depth direction, described backstay under detected state and described measurement sleeve are arranged vertically, and pass the described measurement groove of correspondence position and the overlapping region of described positioning rod slot is connected by locking device.
It is further characterized in that: described backstay is angle square;
Described positioning rod slot also can run through described backstay by depth direction;
On described backstay, there is scale, on described measurement sleeve, have scale.
Adopt after the utility model, backstay is abutted against to the port of workpiece to be detected, move to suitable position and fixed by locking device measuring sleeve, measure sealing surface by measuring moving contact, measurement is quick and easy like this, and the existence of measurement groove and positioning rod slot makes the utility model can measure the product of different size, and the utility model is simple in structure, each assembly replaceability is higher, so easy to maintenance.
