Abstract
The utility model provides a novel vernier caliper for drill-pipe joint thread, belonging to the technical field of measuring tools, and aiming at solving the problem of tedious usage caused by that a prior measuring tool for measuring drill-pipe joint thread can not directly read the specification and type of the drill-pipe joint thread. Metric-system and English-system length scales are respectively carved on the surface of a caliper body, reference lines are carved on a vernier, and back sides of inner measuring jaws and outer measuring jaws of the vernier caliper are prepared in the conicity of 1:4. The novel vernier caliper is simple and practical in structure, and can be applied to measure the specification and type of IF type, FH type, REG type and NC type petroleum drill-pipe joint thread in petroleum, geological drilling crew, oil-field substation, drilling engineering team and relative departments, as well as to measure the length of an object, the width of a groove, the thickness of a component and the like.
Description
Technical field
The utility model belongs to a kind of measurer for measuring tool joint thread in the survey instrument technical field.
Background technology
Growing along with petroleum industry and hydraulic engineering, also more and more higher with the technical requirement of the probing apparatus of drilling rod to drilling well, because it is directly connected to quality and the effect of drilling well.In known technology, the used measurer of existing measurement tool joint thread mainly is the joint screw thread Steel Ruler that adopts or existingly forms common calliper by vernier, scale, vernier.But limit by its structure institute, length, diameter that existing measurer only can the tool joint screw thread convert again, can not directly read the specifications and models of tool joint screw thread, use loaded down with trivial detailsly, and use is made troubles to reality.
Summary of the invention
In order to overcome the deficiencies in the prior art, solve the specifications and models that can not directly read the tool joint screw thread of existing measurer for measuring tool joint thread, use loaded down with trivial details problem.The purpose of the utility model provides a kind of simple and practical, can directly measure and demonstrate the dimensions model of tool joint thread, new-type measurer easy to use.
The technical scheme in the invention for solving the above technical problem is:
A kind of Novel drill rod joint screw thread vernier caliper, it is provided with: blade, vernier, be carved with respectively metric system length groove, length groove made in Great Britain on the chi face of blade, corresponding metric system, length groove made in Great Britain are carved with respectively metric system, datum line made in Great Britain on the vernier.
Above-mentioned Novel drill rod joint screw thread vernier caliper, be carved with respectively outer-diameter threads D (pin thread), internal diameter whorl d (box) groove of drill pipe sub on the chi face of described blade, on the vernier outer-diameter threads D, the internal diameter whorl d groove of corresponding drill pipe sub be carved with respectively the measuring basis line.
Above-mentioned Novel drill rod joint screw thread vernier caliper, be carved with respectively metric system, length groove made in Great Britain on the chi face of described blade, be carved with respectively outer-diameter threads D, the internal diameter whorl d groove of drill pipe sub on the another side chi face, institute's correspondence is carved with datum line on the vernier.
Above-mentioned Novel drill rod joint screw thread vernier caliper, the interior measuring claw of described blade and vernier and the backside of external pelivimetry pawl were made 1: 4 or 1: 6 tapering.
When the utility model used, the same with existing vernier caliper measurement object, needs were measured specification and the model of tool joint thread, at first measure screw thread reamer hole outside diameter, then see the datum line on the vernier; Groove on the corresponding blade of datum line is exactly specification, the model of measured screw thread; When run into two screw thread code names very near the time, measure thread taper with interior measuring claw and external pelivimetry pawl because the specification of tool joint thread is 1: 4 or 1: 6 two kinds of tapering, then judge specification and the model of tested screw thread; When measuring outer tool joint thread, at first measure the coupling Major Diam, then seeing the groove on the corresponding blade of datum line on the vernier scale face, is exactly specification, the model of tested screw thread, thereby large unguiculus is measured the box and pin data and corresponding slide calliper rule back drilling rod data of drill pipe sub.
Because technique scheme has been adopted in the utility model design, has effectively solved the specifications and models that can not directly read the tool joint screw thread of existing measurer for measuring tool joint thread, uses loaded down with trivial details problem.Also show through for several times testing result on trial, the advantage such as it compared with prior art has simple and practically, can directly measure and demonstrate the dimensions model of tool joint thread, and is easy to use, it measures quicklook, and is accurate! And positive data can supporting back DATA REASONING go out the wear intensity of drill pipe sub, thereby detect the abrasion condition of tool joint thread, be applicable to oil, geological drilling team, oil field tubulars substation, drilling engineering team and relevant department and measure model and the specification of IF type, FH type, REG type, NC type oil tool joint thread, can also measure length, internal diameter, the external diameter of object, and groove width, parts thickness etc.
