Abstract
The invention discloses a high precision positioner used for a checker or a graduator of an electromagnetic wave well logger. The positioner comprises a rotary thread tube, a fixed clipping seat and a sliding seat; the fixed clipping seat is provided with a guide rail coaxial with the electromagnetic wave well logger, and the sliding seat can be glidingly installed on the guide rail; and the rotary thread tube is nested on the fixed clipping seat, and an external thread which can drive the sliding seat to slide along the guide rail is arranged on the rotary thread tube. The invention has the advantages that because the sliding seat is driven to slide along the guide rail through driving the rotary thread tube to rotate, not only the positioning is accurate, but also the axial horizontal movement distance of the sliding seat along the electromagnetic wave well logger can be accurately controlled, therefore the error of the response data measured by the graduator or the checker installed on the sliding seat is greatly reduced.
Description
Technical field
The present invention relates to a kind of high-precision positioner that is used for electromagnetic wave logger checker or graduator.
Background technology
The detection of electromagnetic wave logging instrument and scale are one of difficult points of design, and common three-stage graduation device or emission checker are designed to the ring-like dish of specified impedance, move on instrument by simple translation or rotational positioner, thus the data of meeting with a response.But simple locate mode can be brought two main problems:
1, because the machinery cooperation of employing center, location/screens degree of accuracy deficiency, the error that produces when machinery cooperates is bigger, when the diameter of checker/graduator own is big, the small deviation angle in center is reflected on the coil at edge, its degree that departs from the upright position will increase, and this can make the response data error of actual test increase, and can't reach the high accuracy designing requirement of graduator/checker.
2, because locator is fixed on the instrument, and must change its position by mobile graduator/checker disk: this makes us when each mobile checker, must pull down the test cable of connection on it; Simultaneously, when using graduator and checker, also can't adopt mechanical drive mode, make that scale/verification operation efficient is very low.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of high-precision locator that is used for electromagnetic wave logger checker or graduator, can improve the certainty of measurement of graduator or checker greatly.
In order to address the above problem, to the invention provides a kind of high-precision locator that is used for electromagnetic wave logger checker or graduator and comprise: rotation thread barrel, Fixing clamp-seat and sliding seat; Fixing clamp-seat is equipped with the guide rail coaxial with electromagnetic wave logger, and sliding seat slidably is installed on this guide rail; The rotation thread barrel is set on the described Fixing clamp-seat, and described rotation thread barrel is provided with and can drives the external screw thread that described sliding seat slides along described guide rail.
Preferably, also comprise inner core, described inner core is set between described electromagnetic wave logger and the described rotation thread barrel, and is installed on the described electromagnetic wave logger by described Fixing clamp-seat.
Preferably, described guide rail is 3, and circumferentially evenly distributes along described Fixing clamp-seat.
Preferably, also be provided with scale on the described guide rail.
The present invention has following advantage:
1, by driving the rotation of rotation thread barrel, driving sliding seat slides along described guide rail, not only accurate positioning, and can accurately control the distance of sliding seat, thereby greatly reduce the response data error of the actual test of the graduator/checker that is installed on the sliding seat along the electromagnetic wave logger axial translation;
2, adopt circumferentially three uniform guide rails, can lock scale/calibration equipment, it is vertical with logging instrument that it is remained in sliding process;
3, the rotation thread barrel rotation that is enclosed within on the inner core drives the device translation, and inner core and logging instrument are fixed by Fixing clamp-seat, can guarantee with logging instrument coaxial;
4, on three guide rails, be equipped with scale, can write down checker/graduator current location easily.

Fig. 1 is a schematic diagram of the present invention;
Fig. 2 for Fig. 1 from the upper left side to the perspective view of seeing;
Fig. 3 for Fig. 1 from the upper right side to the perspective view of seeing.
The specific embodiment
Shown in Fig. 1～3, the present invention includes: rotation thread barrel 1, Fixing clamp-seat 3 and sliding seat 4; Fixing clamp-seat 3 is equipped with coaxial 2,3 guide rails 2 of 3 guide rails of electromagnetic wave logger 9 and circumferentially evenly distributes along Fixing clamp-seat 3.Sliding seat 4 slidably is installed on this guide rail 2, and graduator/checker 8 is installed on this sliding seat 4.Rotation thread barrel 1 is set on the Fixing clamp-seat 3, and rotation thread barrel 1 is provided with and can drives the external screw thread 6 that sliding seat 4 slides along guide rail 2.Also be arranged with inner core 7 between rotation thread barrel 1 and electromagnetic wave logger 9, inner core 7 is installed on the electromagnetic wave logger 9 by Fixing clamp-seat 3.Also be provided with scale 10 on the guide rail 2, can write down checker/graduator 8 current locations easily.
Fixing clamp-seat 3 can comprise that an end of two semi-ring decks 31,32 and 33,3 guide rails 2 of the collar is fixed on the semi-ring deck 31,32 shown in Fig. 2,3, the other end is fixed on the collar 33.The internal diameter of the collar 33 is in cantilever position greater than the external diameter of electromagnetic wave logger 9.By adjusting design parameters (mainly being the diameter of rotation thread barrel 1 and the internal diameter of the collar 33), in the time of can making 1 rotation of rotation thread barrel, frictional force can not cause the device distortion.The dismounting of locator of the present invention also is convenient in design like this.
In addition, full device of the present invention all adopts nonmetals to make, and the operate as normal to electromagnetic wave logger does not constitute influence like this.
When the present invention uses, make 1 rotation of rotation thread barrel by the swing handle 5 that is installed in rotation thread barrel 1 one ends, drive sliding seat 4 along guide rail 2 translations, thereby guaranteed that checker/graduator 8 keeps very high-precision along logging instrument 9 and moves, greatly reduced the response data error of graduator/checker 8 actual tests.
In sum; being preferred embodiment of the present invention only below, is not to be used to limit protection scope of the present invention, therefore; all any modifications of being done within the spirit and principles in the present invention, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
