DEVICE FOR MONITORING geometric dimensions and parameters of pipes and couplings, ALSO ring gauge and plug gauge

摘要

Use: control of internal and external thread and the sealing surfaces of joints of tubing, casing and coupling them according to GOST 632-80, 633-80 and other elements, advantageously Sealed threaded pipe connections..; Objective: simplification of control procedures and increase its accuracy by eliminating the subjectivity of assessment of controlled parameters, and creating a rather simple construction providing control not only the thread feature, but simultaneous control of the sealing member and its location relative to the thread.; SUMMARY: In an apparatus for controlling elements of pipe thread connections, comprising a threaded ring gauge and a plug gauge, smooth gauge ring and the gauge tube, as well as means for controlling the linear distances, according to the proposed utility model, gauge ring and / or caliber -probka formed composite, wherein the threaded bore is provided with a cylindrical guide surface provided coaxially with the threaded and smooth bore provided with corresponding rigidly connected with it the guide element cooperating with the guiding second surface of the threaded gauge with the ability of translational axial and rotational movement smooth caliber relative threaded gauge to provide a snug fit of the working surface of a smooth gauge to the sealing surface of the test object, wherein on expiry controlled products are judged by the distance from the end of the test object to the measuring plane of the threaded gauge and the measuring plane smooth caliber while close contact test object with thread m and smooth gauges.; Gauge ring formed composite of a threaded ring gauge and a smooth ring gauge, the outer cylindrical surface of the threaded gauge formed coaxial with the threaded and smooth bore provided with a rigidly associated with it a guide ring mounted on the outer cylindrical surface of the threaded gauge in translation and rotation to ensure a snug fit of the working surface of a smooth gauge to the sealing surface of the test article, the expiry of controlling the emogo products are judged by the distances from its face to the measuring of the threaded gauge plane and to the measuring plane of a smooth caliber while close contact controlled product as a threaded and a smooth caliber, and in the smooth caliber provided a window to allow measurement of the distance from the end of the controlled products to the measuring plane thread gauge.; Measuring plane is the plane of the threaded gauge caliber end face adjacent to the smooth caliber, and measuring the smooth plane is a plane caliber opposite end.; Plug gauge formed composite of a threaded plug gauge and a smooth plug gauge, wherein the threaded bore is provided with an inner cylindrical guide surface provided coaxially with the threaded and smooth bore provided with a rigidly associated with it a guide member mounted in the inner cylindrical guide surface of the threaded caliber in translation and rotation to provide a snug fit of a smooth working surface to control the caliber of the sealing surface of product, wherein expiration of the test object is judged by the distance from its end, to the measuring plane of the threaded gauge and the measuring plane smooth caliber while close contact of controlled items, both threaded and smooth with calibers.; Measuring plane of a smooth-tube gauge is its plane of its free end, and the measuring plane threaded plug gauge is a plane end face, located on the opposite side with respect to the measuring plane of a smooth-tube gauge. 3 n.p.f. 2 FIG.
