Description
Technical field
The utility model relates to the screw threads of petroleum drilling tools field of measuring technique, is a kind of special-purpose machinery clamping device of screw threads of petroleum drilling tools gauge calibration.
Background technology
The screw threads of petroleum drilling tools gauge is the external thread gauge that has certain taper, as tapering 1:4 or 1:6.The drilling tool external thread gauge comprises feeler gauge and ring gauge, and feeler gauge and ring gauge use in pairs.Difference according to thread rotary orientation is divided into left-handed drilling tool external thread gauge and dextrorotation drilling tool external thread gauge again.Because the purposes difference is divided into working gauge, reference gauge, regional gauge and four kinds of accuracy classes of original gauge with the drilling tool external thread gauge, magnitude tracing concerns successively from low to high.Working gauge is mainly used in oil drilling tools such as check drilling rod, drill collar, square kelly and connects the tight distance value of using threaded connector; Reference gauge is mainly used in the tight apart from value of calibration operation gauge; The area gauge is mainly used in the tight apart from value of calibration reference gauge; Original gauge is mainly used in the tight apart from value of the regional gauge of calibration.Higher level's drilling tool external thread gauge is calibrated subordinate's drilling tool external thread gauge in a word, with the wear extent of determining subordinate's drilling tool external thread gauge or variable quantity whether in master gauge definite value scope, guarantee the accurate to dimension and the interchangeability of oil drilling tools connecting thread, improve the safe reliability that drilling tool is threaded.
Closely having reflected the degree of the deviation combined influences such as tapering, pitch, tooth depth, tooth form angle, middle footpath of screw thread apart from value (standoff), is the most important parameter of evaluation screw processing quality.According to API Spec 7-2001 " rotary drill column member standard " (API Std) requirement, working gauge, reference gauge, regional gauge etc. all will carry out period regulation.The calibration of we domestic mainly carry out the work gauge and reference gauge, regional gauge need be delivered to America NI ST calibration.During calibration, the feeler gauge of gauge at the same level and ring gauge need closely screw, and simultaneously also will be respectively exchange with the ring gauge of higher level's gauge and feeler gauge closely to screw, to record autogamy closely apart from the S value with exchange closely apart from S again
1Value and S
2Value.
Among " rotary drill column member standard " API Spec 7-2001, as follows to the calibration steps requirement of the tight distance of screw threads of petroleum drilling tools gauge:
Consult Fig. 1.Can not screw fast with hand-screw bench drill tool external thread gauge and to put in place, the moment of torsion weight 1 of use institute control gauge specification specifies quality and the lever arm 3 of specified length are finished and are screwed, moment of torsion weight 1 hammering process is the movement of falling object of specified altitude, generally requires hammering 12 times.Drilling tool feeler gauge 5 handles should be securely fixed in the bench vice when screwing, should use heavy bench vice, and be securely fixed on the worktable.Because closely apart from value, the tight distance value of particularly bigger drilling tool external thread gauge can be subjected to the influence of stationary installation rigidity.When hammering, drilling tool feeler gauge 5 cooperates with ring gauge is hand-tight, and insert in the drilling tool ring gauge 6 circumferential circular holes lever arm 3 ends, and cooperates with hole wall is appropriate, and should keep lever arm 3 parallel with surface level 4, can guarantee that so just weight 1 does the movement of falling object along vertical rod 2.In drilling tool external thread gauge calibration process, need to use traditional heavy bench vice clamping drilling tool feeler gauge 5; In the hammering process, need repeatedly unclamp, tighten bench vice,, guarantee that lever arm 3 is parallel with surface level 4 to adjust the horizontal level of lever arm 3.
Because the bench vice clamping device is simple, takes time and effort, and has a strong impact on calibration operation efficient, needs repeatedly to unclamp, tighten bench vice in the primary calibration process; And cause the drilling tool external thread gauge to fall easily, cause taking place security incident.
Summary of the invention
