Description

The non-involute former
Technical field:
The utility model is relevant with material standard with the accuracy detection of gear measurement machine.
Background technology:
The tradition of gear measuring instrument (GMI) precision is demarcated or detection method roughly is divided into two classes: instrument individual event accuracy detection and instrument synthesis precision detect.The former according to the instrument error mathematical model of setting up, determines the accuracy of detection of gear measuring instrument in the measurement range space by instrument individual event precision such as each the coordinate axis kinematic accuracy of gear measuring instrument and instrument detection accuracy are detected; The latter then adopts material standard---and the master gear that gear involute model or process accuracy detection were demarcated comes the integrated measurement accuracy of gear measuring instrument is detected evaluation.Usually the two is used in combination.
Demarcate with the gear involute model, identify, during the precision of check gear measuring instrument, the size of gear involute model should be tried one's best and the measurement range of instrument, especially is close with the detected gear product size of user.Because the gear measuring instrument that this model of process was identified is when the detection of gear product, the result of detection can be more accurate.The involute model base radius r that determines in the national standard ' GB/T6467-2001 gear involute model ' of China's issue at present bRange of size 25-400mm, in fact China factory at present can be as the involute model of volume production product export, its maximum base radius r bBe 300mm.Obviously, this can not cover and satisfy the needs of large gear accuracy detection, and also and at present the measurement range of 2 meters and 3 meters gear detecting instruments being had of China greatly differs from each other.There are same difficulty in detection, examination, the staking-out work of import large gear surveying instrument---and lack the large scale involute model and be used for the benchmark transmission that the gear wheel flank profil is measured, measurement range reaches 3 meters gear measurement machine, but can only be by base radius r bIt is of common occurrence that the following involute model of 200mm carries out the helpless situation that accuracy of instrument checks and accepts.The necessity of exploitation large scale involute model is with urgent self-evident.
Adopt the non-involute model in recent years: round pin combination model, ball and the cylinder of cutting sth. askew combination model, plane model and ball-type model carry out the flank profil measuring accuracy to the involute gear surveying instrument and demarcate to detect and be developed and approve.But it measures track and large scale involute profile shape still has certain error.
The utility model content:
The purpose of this utility model provides a kind of simple in structure, make easy, easy to use, accuracy of detection height, the non-involute former that can trace to the source.
The utility model is achieved in that
The utility model non-involute former, plate body sleeve 5 is vertical mutually with the axis of crossbeam 6, each is connected the axis two ends of crossbeam 6 with a reference block 7, mandrel 1 is the step axle, there is center hole at its two ends, the endoporus interference fit of mandrel 1 and sleeve 5, one end of sleeve 5 is connected with the mandrel step, the other end is connected by the pad on the mandrel 3 and nut 2 and mandrel 1, and said reference block is that the cross section is the thin tooth bar of monodentate that the cone of isosceles trapezoid or angle block gauge that the cross section is isosceles trapezoid or cross section are isosceles trapezoid.
There is the reinforcement 4 of symmetry crossbeam axis both sides.
The utility model promptly adopts the non-involute model to substitute traditional involute model based on the theory of international standard approval.Characteristics at the involute urve gear wheel: the gear wheel base radius is big more, the involute shape of gear-profile and and the skew lines that forms an angle of gear teeth line of symmetry between theoretical error be more or less the same, so the utility model adopts the thin tooth bar basic pattern of monodentate that has circular cone benchmark, the angle block gauge benchmark of corresponding cone angle or have a respective angles to substitute the gear wheel involute model.
Three kinds of novel non-involute material standards---pyramid type model, angle block gauge type model and monodentate approach the rack type model in the patent proposition, the demand that precision is identified and benchmark transmits when detecting the large scale involute urve to satisfy gear measurement machine has the feasibility and the simplification of processing and manufacturing simultaneously.
The utlity model has following characteristics:
1. make easyly, be particularly suitable for replacing large scale involute profile model.
2. but the thin tooth bar of benchmark circular cone, benchmark angle block gauge and benchmark monodentate all has good precision traceability;
3. the measurement track of benchmark body on xsect is skew lines, the angle of benchmark body and tested pressure angle are consistent or are approaching, under the situation that large scale gear is measured and the stripped deviation of actual tested involute profile shape little, help improving measuring accuracy;
4. can be used to detect left and right profile accuracy simultaneously;
5. need special measurement software, the theoretical error of compensating line and tested involute urve.
The comparison and the advantage of the non-involute model in the utility model and the international standard:
1. the non-involute benchmark of this patent is with the circular cone of certain cone angle or with the angle block gauge or the thin tooth bar of monodentate of certain profile angle, and is all different with the shape of plane, straight pin and ball model benchmark in the standard, parameter etc.
2. because reference measurement track of the present utility model is the angled straight lines with certain angle, compare with the measurement track of non-involute models such as plane, straight pin type and ball-type in the international gear standard, more approaching with large scale involute profile shape, thereby reduced the measurement stroke of detection probe, also reduce the theoretical error compensation range, helped the raising of measuring accuracy.And the various non-involute models in the international standard are more suitable for the measurement of small size involute gear tooth profile, for the measurement of large scale involute urve, even fully may be because range is too big, exceed the working range of measuring sonde sensor and can't carry out.
3. the theoretical error computing formula between reference measurement track and the involute urve is different with corresponding calculating compensation software.
4. for the location positioning precision of measuring sonde, all high, more responsive than requiring under the involute model detection case when adopting the non-involute model; But when the large scale involute urve was measured, because measurement track of the present utility model and involute urve are very approaching, to the probe positions positioning accuracy request, other existing non-involute model did not need too high requirement relatively.
5. measuring process and existing involute model is the same.(1) with gauge head positioning reference spare, accurately locatees the gauge head locus; (2) gauge head is accurately adjusted to theoretical compensating gage and count initial point; (3), simultaneously the software compensation function is placed the compensation calculating reference point with measuring error zero setting; (4) mobile gauge head to involute profile is measured reference position; (5) start apparatus measures position to terminal; (6) metrical information and the synchronous theoretical compensated information of computing machine that obtain of apparatus measures probe sensor reaches computing machine in real time, carry out obtaining the instrument synthesis precision of apparatus measures involute profile after the data processing, adopt of detection or the demarcation of this patent non-involute model the involute urve measuring accuracy of gear measuring instrument thereby finish.
