Abstract
The utility model discloses a kind of annular wheel common normal micrometer measurement mechanism, the scale of milscale and dynamic chi are all connected with extension rod, two extension rods are arranged in a crossed manner, and are flexibly connected at point of crossing place.Feature of the present utility model is: played the potential function of milscale, directly and accurately can measure annular wheel common normal size, the particularly made allowance common normal size of intermediate step, the constraint, state etc. of dimension limit directly can be perceived after measurement, indirect size need not be used convert, more accurately, conveniently, efficiently.
Description
Technical field
The utility model relates to a kind of survey instrument, is specifically related to a kind of annular wheel common normal micrometer measurement mechanism.
Background technology
Under normal circumstances, form of gear tooth processing, tolerance detect and represent by common normal tolerance, and this is one of important indicator of gears meshing precision, namely represents the physical profiles size of the form of gear tooth by common normal size.External gear pump is that two external gear drivings run, relatively simpler, and internal gear is an annular wheel and an external gear driving operation, relatively complicated, during internal gear engagement, wherein outer rotor is equivalent to entity axle, and annular wheel is equivalent to entity hole, common normal is not easily measured, although can detect with indirect size distance over bar, but in usually processing, distance over bar is not very convenient, as modulus is bigger than normal, size less than normal, profile of tooth leaves the size of process redundancy, size etc. before thermal treatment roll flute, workshop does not accomplish that each step operation all goes to calculate relative size distance over bar numerical value at the scene, be converted into actual common normal size again, so extremely not science, inconvenient, not directly perceived, computation and measurement is difficult to distance over bar.
Utility model content
The purpose of this utility model is to overcome above-mentioned not enough problem, provides a kind of annular wheel common normal micrometer measurement mechanism.
The technical scheme that the utility model is adopted for achieving the above object is: annular wheel common normal micrometer measurement mechanism, and the scale of milscale and dynamic chi are all connected with extension rod, and two extension rods are arranged in a crossed manner, and is flexibly connected at point of crossing place.
Described extension rod free end is provided with spherical point contacts.
Described dynamic chi is provided with digital display meter.
Described digital display meter is provided with Tiao Chi mechanism.
Feature of the present utility model is: played the potential function of milscale, directly and accurately can measure annular wheel common normal size, the particularly made allowance common normal size of intermediate step, the constraint, state etc. of dimension limit directly can be perceived after measurement, indirect size need not be used convert, more accurately, conveniently, efficiently.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model measuring principle figure.
Wherein: 1, extension rod 2, scale 3, dynamic chi 4, digital display meter 5, Tiao Chi mechanism 6, chi body 7, spherical point contacts 8, annular wheel W, common normal size.
Embodiment
As Fig. 1, shown in 2, chi body 6 end winding support of milscale has scale 2, dynamic chi 3 is arranged on chi body 6 and also can slides on chi body 6, described scale 2 and dynamic chi 3 are all connected with extension rod 1, two extension rods 1 are arranged in a crossed manner, and be flexibly connected at point of crossing place, slip on chi body 6 of the servo-actuated chi of distance 3 of two extension rod 1 free ends and to change and proportional, preferred 1:1 ratio, data can directly draw without the need to converting, for ensureing measuring accuracy, described extension rod 1 free end is provided with spherical point contacts 7, the involute urve inner toothed surface of annular wheel 8 is contacted by two spherical point contacts 7, to measure the common normal size W of annular wheel 8 more accurately, and it is truer to measure feel, the particularly made allowance common normal size W of intermediate step, the constraint of dimension limit directly can be perceived after measurement, state etc., indirect size need not be used convert, digital display meter 4 installed by described dynamic chi 3, reading more quick and precisely, reduce error, and Tiao Chi mechanism 5 is set on described digital display meter 4, ensure precision, reduce error.
By above-mentioned design, the testing of the common normal size W of annular wheel 8 can easily, simply, accurately, intuitively, efficiently complete, and has played the potential function of milscale.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to the technical solution of the utility model and inventive concept thereof and replace or change, all should be encompassed within protection domain of the present utility model.
