Description
The invention belongs to the measurement mechanism of mechanical manufacturing field.
In the degree error measure of garden,, many requirements are arranged again in the use, so the V-type mensuration is still in a large amount of employings because garden degree instrument costs an arm and a leg.V-type is surveyed method and is claimed three point measurement methods again, belongs to measurement features parameter detecting principle.The standard (ISO/DIS4292) of relevant this mensuration of International Organization for Standardization; Other country, as American National Standard (ANSI B89.3.1-1972), British standard (BS) (B.S3730-1964) etc. has also all been made special regulation to three point measurement methods.China has formulated special standard (GB4380-84 determines the method for garden degree error---2 points, three point method).
Following relation is arranged between the garden degree error amount that records with three point method and the true garden degree error of measured piece:
f＝Δ／F （1）
The actual garden of f-degree error amount wherein, Δ-measured value (being indicator full-scale reading difference), F-reflects coefficient.
The reflection coefficient is revised the coefficient of measured value for 2 points, when three point method is measured garden degree error.This coefficient is measured value and the ratio of real garden degree error in theory, and it has reflected that measured value is to the amplification of true garden degree error amount or dwindle degree.
In measuring process, the influence that the reflection coefficient is subjected to V-type angle [alpha] and measured piece rib to count n.When one timing of α angle, reflect that then coefficient only depends on the rib number of measured piece.For example: when the V-type angle is 60 °, the rib number is 3 o'clock, reflects that then coefficient F=3(is according to GB4380-84), if measured value Δ=18 μ m, then the true garden degree error of this measured piece is
f＝ (Δ)/(F) ＝ 18/3 ＝6（μm）
Can be drawn in garden degree three point method is measured by top narration, the measured piece rib is counted n, and following relationship is arranged between reflection coefficient F and the actual garden degree error:
Determine that rib number → then can select reflects coefficient F → and then can accurately obtain the actual garden degree error of measured piece.
Therefore, guarantee that the key of three point method measuring accuracy is the rib number that accurately draws measured piece.
But the problem that exists during three point method is measured at present is: although in international and the domestic standard, all stipulated corresponding reflection coefficient for the garden tee section of different rib numbers, and in the actual measurement process because the rib number is not generally all known in advance, therefore can't adopt corresponding reflection coefficient, draw the true garden degree error amount of measured piece, for example patent (1) GOIB5/24 S01048300 8600046, the garden degree error detecting apparatus of part; (2) the branch garden degree measuring instrument of GOIB5/28 S01035480 8600052 article for rotation.
In sum as can be seen, in garden degree error three point method is measured, how to determine the rib number, and then select corresponding coefficient of comparisons to revise, the actual garden degree error amount that draws measured workpiece is the key that guarantees its measuring accuracy.
The present invention is exactly according to above-mentioned deficiency, develop the rib number that a kind of automatic measurement, sampling, correction and process analysis of spectrum computed in software go out measured piece, select corresponding reflection coefficient, a kind of garden degree three point method that draws the true garden degree error of measured piece at last detects and data processing equipment automatically.Main points of the present invention are its gearing by floating type soft connection, include axle and the rotating disk that can be two driving lever balls, have the snap ring that can be two cramp bars, measured workpiece, can be the coupling arrangement of the elastic webbing composition of rubber nylon braiding, by two V-type bodies that can be surperficial welding-on high-abrasive material, can be the screw mandrel of left and right sides spiral, can be front and back totally four supporting positioning compression devices that fork is formed, by making the three-dimensional survey sensor of adjusting motion, the sliding shoe that has guide rail, measurement adjusting gear that chuck is formed and data processing equipment are formed.
In order to reduce the influence of power source to measurement mechanism, the belt of the speed reduction unit of gearing drives turntable shaft with the output of speed reduction unit by belt, and makes the driving lever ball on the rotating disk stir the elastic webbing of rubber nylon braiding, drives the cramp bar that is fixed on the snap ring.Snap ring is clamped on the measured workpiece by screw, and the drive workpiece rotates together.Turntable shaft is bearing on sliding bearing and the bearing, is used for adjusting the upright position of turntable shaft, makes the measured workpiece line of itself and different-diameter keep contour.After the adjustment of turntable shaft upright position was suitable, by locking coin nail, screw thread briquetting and briquetting with holes were locked.
The Work-sheet pressing of its supporting positioning compression device adopts the screw mandrel that has left and right sides spiral, and the deflection method that makes its rotation drive four forks in front and back realizes.The position of the pressure regulating screw on the mobile fork head changes the tension force of spring.Easy to loading and unloading for the ease of measured workpiece, four forks are connected the support that compresses that is positioned on the slide by the pivot pin screw, can load onto easily or take off.Place two slides above the pedestal square guide rail, carrying V-type body and clamp system.According to the length difference of measured workpiece, can adjust the slide position, can be behind the location by housing screw and pressing plate locking.
It is measured can make the three-dimensional survey sensor of adjusting motion in the adjusting gear, can vertically move along the dovetail guide of pedestal with slide unit, column, adjust position between the disalignment of tested workpiece, it does transverse movement along horizontal dovetail guide together with slide rail, so that make gauge head be in the bus position, top of measured piece.Survey sensor is made vertical displacement movement along the little guide rail of the vertical dovetail guide T of collet bore type respectively with chuck, sliding shoe, and gauge head can turn round around longitudinal axis in company with deflexion disk, to satisfy the requirement of asymmetric three point measurements.
The signal that survey sensor records, deliver to inductance amesdial after, through A/D(mould/number) converter enters microcomputer interface.Determine measured workpiece rib number according to analysis of spectrum software, select coefficient of comparisons, calculate the true garden degree error numerical value of measured workpiece as calculated after the machine maintenance just.
The present invention is again a kind of easy and can measure automatically and revise, and is applicable to the Workshop Production scene, and the garden degree three point method with degree of precision is measured and data processing equipment automatically.When it has fundamentally overcome present three point method survey garden degree error, can't select to reflect the defective of coefficient owing to do not know the rib number, thereby can improve the measuring accuracy of this method greatly; Replenished again on the other hand because garden degree instrument in price with the restriction of using, can be used as and had degree of precision and low price again, garden degree measurement mechanism easy to use.The present invention can directly use in the production scene.
