Abstract
The utility model relates to a special measuring tool for a stator cavity of a screw rod drilling device, which is composed of an inner diameter dial test indicator 1, a lengthened rod 2, a measuring head 3 and a rolling measuring head 4. Since the utility model adopts that the inner diameter dial test indicator is connected with the lengthened rod, and is respectively connected with the measuring head and the rolling measuring head, the measuring surface is changed into rolling contact from the contact of ordinary measuring tool points and the precision of measuring dimension is high. End surface measurement is changed into multiple-cross section measurement. Compared with other measuring tools, the special measuring tool for a stator has the advantages of high technical content and high measuring precision and can be applied to the measurement of all similar screw inner gears. The utility model has the advantages of high measuring dimension precision, good use situation, simple structure and convenient use, and is suitable for on-site popularization and application.
Description
Technical field:
The utility model relates to the subsurface tool that uses on a kind of oil drilling, particularly a kind of helicoid hydraulic motor bore of stator special measurement instrument.
Background technology:
Motor is the power part of helicoid hydraulic motor, the condition that the rotor of a positive displacement hydraulic motor and stator should possess: can seal, be that rotor and stator curved surface should be formed the space and grip pair altogether, hold actuating medium to form a plurality of annular seal spaces of gripping altogether, the continuous kinetic energy of rotor causes annular seal space to move down vertically continuously, to guarantee that actuating medium advances in proper order downwards, in order to guarantee the sealing in motor seal chamber, with the pressure drop of guaranteeing to bear, so the fit dimension between rotor all needs through the apolegamy test, make it should not be too tight or too loose, allow motor bring into play maximum efficient, therefore the engagement of rotor and stator seems particularly important, and the actual processing dimension of rotor is to be determined by the size of diameter of stator bore, if the diameter of stator bore dimensional measurement is inaccurate, the outside dimension that calculates rotor is just inaccurate, and rotor just can not satisfy the pacing items that forms hydraulic motor when meshing with stator.And conventional measurer can't use when measuring stator.
Technical scheme
The utility model purpose is to provide a kind of helicoid hydraulic motor bore of stator special measurement instrument, and it is to measure accurate, easy to operate helicoid hydraulic motor bore of stator special measurement instrument.
The utility model purpose is to realize like this, it is made up of dial bore gage (1), extension rod (2), measuring head (3), tolling measurement head (4), on dial bore gage (1), be connected to extension rod (2), and be connected to measuring head (3), tolling measurement head (4) respectively.
It is according to the special shape in stator rotor cross section and the engagement characteristics of motor pair, by analysis, as long as measure the physical size that the diameter of stator bore size just can calculate processing rotor, the stator cross section is a cycloid, therefore, we improve the gauge head of dial bore gage, changing gauge head one end into the usefulness rolling bearing contacts with helicoid, the other end changes socket cap into and contacts with helicoid, is convenient to find peak like this, and conventional dial bore gage bar is shorter, it is not enough to fathom, can only measure the end, common dial bore gage sounding rod is become extension rod, so that measure a plurality of stator sectional dimensions.
The utility model is connected to extension rod owing to having adopted on dial bore gage, and is connected to measuring head, tolling measurement head respectively, and measurement face becomes the contact of rolling, measurement size precision height by the contact of ordinary measring tool point.End surface measurement becomes multi-section and measures.Compare with other survey instrument, stator special measurement tool technique content height, the measuring accuracy height can be tried out in the measurement of all similar spiral annular wheels.Measurement size precision height, operating position is good, and is simple in structure, easy to use, is well suited for field popularization application.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment
As shown in the figure, the utility model is made up of dial bore gage 1, extension rod 2, measuring head 3, tolling measurement head 4, is connected to extension rod 2 on dial bore gage 1, and is connected to measuring head 3, tolling measurement head 4 respectively.Measuring head 3 can be changed according to the helicoid hydraulic motor model specification, and tolling measurement head 4 is by the rolling bearing manufacturing.
Claims (2)
1, a kind of helicoid hydraulic motor bore of stator special measurement instrument, it is made up of dial bore gage (1), extension rod (2), measuring head (3), tolling measurement head (4), it is characterized in that: on dial bore gage (1), be connected to extension rod (2), and be connected to measuring head (3), tolling measurement head (4) respectively.
2, a kind of helicoid hydraulic motor bore of stator special measurement instrument according to claim 1 is characterized in that: measuring head (3) can be changed according to the helicoid hydraulic motor model specification, and tolling measurement head (4) is by the rolling bearing manufacturing.
