Abstract
The invention discloses a measuring apparatus of the diameter of the internal sealing face of an oil pipe, which mainly comprises a gauge stand 2, an indicating gauge 4, a fixed measuring head 1 and amovable measuring head 7. The position of the central axis of the gauge stand 2 is provided with a through hole 3 which is matched with the inside diameter of a shaft sleeve arranged on the indicating gauge; the indicating gauge 4 is fixed on one end of the gauge stand 2; the upper end of a measuring rod 8 of the indicating gauge can retract in the through hole 3 of the gauge stand; the fixed measuring head 1 is connected with the other end of the through hole 3 of the gauge stand; the movable measuring head 7 is connected with the tip of the measuring rod 8 of the indicating gauge; and the measuring heads, the through hole of the gauge stand and the measuring rod of the indicating gauge are on the same axis. The measuring apparatus of the invention can directly and accurately measure andjudge whether the diameter of an interior seal face is qualified, conveniently measure the accurate data of the diameter of the interior seal face and provide information for data adjustment of machining by a machine tool. The measuring apparatus is convenient and quick in measure, high in sensitivity, good in repeatability, simple in structure and easy to manufacture.
Description
Technical field
The present invention be a kind of be the gauging instrument of feature to adopt mechanical measuring means, be specifically related to a kind of surveying instrument of measuring diameter of internal sealing face of oil pipe.
Background technology
For many years, connection between the oil pipes be rely on the external thread of body leading portion and with it the internal thread of the box cupling of adaptation realize, the internal thread at box cupling two ends and body external thread screw, one one couples together, reach managing the sealing of interior oil or gas by combining closely between screw thread, be thread seal.This seal form not only accuracy requirement of double thread is very high, and its effect does not often reach higher sealing index request.In recent years, people find the better mode of a kind of sealing effectiveness, and the sealing surface that promptly adopts the oil pipe end cooperates original thread seal the tube and tube junction to be carried out the sealing of two kinds of forms as main seal form again.So-called sealing surface, be divided into pipe sealing face (external seal face) and pipe collar sealing surface (inner sealing surface), the external seal face is one section conical surface of gas pipe thread front end, inner sealing surface is one section conical surface at pipe collar screw thread rear portion, this conical surface and pipe collar inwall form a sealed step, the external seal conical surface is consistent with interior sealing cone taper direction, when pipe and pipe collar screw jam-packed, inside and outside two sealing surfaces come in contact, the pipe end that is pipe contacts with pipe collar sealed step face, and when internal and external threads further screwed, the sealing surface at two ends was with regard to mutual extrusion and certain elastic deformation takes place, two sealing surfaces are fitted tightly together, better sealing effectiveness has been arranged.
But, processing to inner sealing surface all is to be finished by the programmed control of numerically-controlled machine now, error amount measurement to processing component does not also have special surveying instrument, if lathe breaks down, when particularly cutter has wearing and tearing, the processing of sealing surface diameter does not often just reach the requirement of design objective, therefore can produce substandard products and waste product.Up to now, both at home and abroad also not about any public technology data of measuring apparatus of diameter of internal sealing face of oil pipe device, domesticly do not see the surveying instrument that a kind of special use is arranged yet.
Summary of the invention
The object of the present invention is to provide a kind of measuring apparatus of diameter of internal sealing face of oil pipe, by of the relative measurement of this measuring instrument to product sealing surface diameter, whether qualified, can provide necessary adjustment data in process for machining tool simultaneously if detecting product to be processed.
The technical scheme that realizes above-mentioned purpose is: measuring apparatus of diameter of internal sealing face of oil pipe, mainly form by gauge stand, indicating gauge, fixation measuring head and movable measuring head.There is a through hole that adapts with described indicating gauge Upper shaft sleeve internal diameter the central axis position of described gauge stand, and indicating gauge is fixed on gauge stand one end, and the sounding rod upper end of indicating gauge can stretch in the through hole of described gauge stand; Described fixation measuring head is connected the other end of described gauge stand through hole, and described movable measuring head is connected the sounding rod termination of indicating gauge; Two measuring heads are the identical sphere of size, and the sounding rod of measuring head, gauge stand through hole, indicating gauge is on the same axis.
During measurement, earlier according to the measured tube diameter size, select matching used U-shaped diameter calibrated bolck, indicating gauge is returned to zero, then measuring instrument is put in pipe collar, two measuring head levels are positioned on the step of pipe collar inner sealing surface, and guarantee that the termination of two measuring heads contacts with the circumferential wall at the same radial line of inner sealing surface two ends, this moment, the deviation of indicator gage finger and zero-bit was the inner sealing surface diameter deviation.
Measuring apparatus of diameter of internal sealing face of oil pipe of the present invention can be intuitively, whether qualified measure the diameter of judging inner sealing surface exactly, and can measure the accurate data of inner sealing surface diameter easily, for the data adjustment of machine tooling in time provides information.This measuring instrument is measured convenient, highly sensitive, good reproducibility, and simple in structure, makes easily.
Description of drawings
Fig. 1 is the whole Facad structure synoptic diagram of one embodiment of the invention.
Fig. 2 is the vertical view of measuring instrument shown in Figure 1.
Among the figure: 1. fixation measuring head, 2. gauge stand, 3. gauge stand through hole, 4. indicating gauge, 5. shift fork, 6. shift fork seat, 7. movable measuring head, 8. sounding rod.
Embodiment
The present invention is described in further detail below in conjunction with drawings and Examples:
As depicted in figs. 1 and 2, measuring apparatus of diameter of internal sealing face of oil pipe of the present invention mainly is made up of fixation measuring head 1, gauge stand 2, indicating gauge 4 and movable measuring head 7.Upper shaft sleeve internal diameter with the indicating gauge 4 gauge stand through hole 3 that adapts is arranged on the central axis of gauge stand 2, the Upper shaft sleeve of indicating gauge 4 is plugged in the through hole 3 of gauge stand 2, and makes indicating gauge 4 and gauge stand 2 relative fixed.Fixation measuring head 1 links by spiral shell and connects or inserting mode is connected the other end of gauge stand through hole 3, movable measuring head 7 is fixedly mounted on the termination of indicating gauge sounding rod 7, fixation measuring head 1 and movable measuring head 7 dorsad, and and sounding rod 8 all be on the same axis.
As a kind of improvement of the present invention, at measuring staff 8 leading portions of indicating gauge a shift fork seat 6 is installed, be fixed with a shift fork 5 (as shown in Figure 1) that is used to promote sounding rod 8 on the shift fork seat 6.The measuring instrument of this structure is more convenient to operate in measuring process.
The present invention can measure the inner sealing surface of different-diameter.If when meeting the bigger sealing surface of diameter, fixation measuring head 1 is unloaded, connect the extension rod of a definite length in gauge stand through hole 3 terminations, fixation measuring head 1 is installed on the extension rod gets final product again.Described extension rod is the par of a cover and the matching used different length of measuring instrument of the present invention, and there is the connector that is complementary with gauge stand through hole 3 and fixation measuring head 1 at the two ends of bar.
