The purpose of this utility model is to provide a kind of deviation from cylindrical form measuring apparatus, solves the problem that existing deviation from cylindrical form measuring apparatus precision is low.
The technical scheme that the utility model adopts is: a kind of deviation from cylindrical form measuring apparatus, comprises test aircraft, test aircraft is fixed with and supports pin, and test aircraft is connected with gauge stand and tested district successively.
Feature of the present utility model is also:
Screw is fixed in test aircraft by installing to support pin.
Test aircraft is provided with adjustment screw, for adjusting the position of gauge stand.
Test aircraft is provided with angle vernier main scale groove.
Gauge stand is provided with survey table, gauge stand is provided with angle vernier scale groove.
Survey table can also be fax sensor.
Support pin and have two.
The beneficial effects of the utility model are: a kind of deviation from cylindrical form measuring apparatus, utilizes cursor principle, the position of adjustment gauge stand, meet the measurement of the deviation from cylindrical form of strange rib circle, the even rib each form of circle; Change survey table into fax sensor, it is possible to the error waveform at the record tested position of part, and rotate the number of peak or the paddy formed for one week from tested part, accurately determine the rib number of part tested position cylindricity; Use the optimizational function of engineering software, analyzed angle value corresponding to different rib number and scale-up factor so that three point method measuring method range of application has increased, and the corresponding raising of sensitivity; In addition, this apparatus structure is simple, and cost is low, is easy to promote.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of deviation from cylindrical form measuring apparatus of the utility model;
Fig. 2 is the enlarged view of test aircraft in a kind of deviation from cylindrical form measuring apparatus of the utility model.
In figure, 1. survey table, 2. adjust screw, 3. test aircraft, 4. support pin, 5. tested district, 6. gauge stand, 7. angle vernier main scale groove, screw, 9. angle vernier scale groove are 8. installed.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The structure of a kind of deviation from cylindrical form measuring apparatus of the utility model, as shown in Figures 1 and 2, comprises test aircraft 3, test aircraft 3 is fixed with and supports pin 4, test aircraft 3 is connected with gauge stand 6 and tested district 5 successively, and screw 8 is fixed in test aircraft 3 by installing to support pin 4, and test aircraft 3 is provided with adjustment screw 2, for adjusting the position of gauge stand 6, test aircraft 3 is provided with angle vernier main scale 7, gauge stand 6 is provided with survey table 1, and be provided with angle vernier scale groove 9, survey table 1 can also be fax sensor, and supporting pin 4 has two.
This device is adopted to be measured by deviation from cylindrical form in conjunction with three point method, principle is: for the axle journal that size is certain, prior art adopts and places it on the inclined-plane of V-block, and respectively have one to contact position (tangency location) with two inclined-planes, this device supports pin 4 and contacts with tested part and to measure in this position, its effect be the same with V-block to tested part enforcement three point method measurement. Simultaneously, when adopting three point method to measure, survey table is biased certain angle beta relative to the plane of symmetry of V-block, the sensitivity to deviation from cylindrical form rib number can be alleviated, this device adopts vernier scale principle to determine the position of survey table, for setting different �� value, measures to adapt to the cylindricity of different rib number, and the structural performance of its hand-held formula, also solve the problems of measurement of the cylindricity of multidiameter neck.
Table 1 is the optimization module in utilizing works software pro/E, for the measurement of the deviation from cylindrical form of different rib number, respectively there is a best angle value, and when this optimum angle angle value, the cylindricity of different rib number is measured, sensitivity increases mostly, namely the value shown is greater than actual value, under thus drawing the angle value prerequisite for different rib numbers, optimization, the scale-up factor that different rib number deviation from cylindrical form is measured, listed by table 1. As can be seen from Table 1, three point method not only is suitable for measuring the deviation from cylindrical form of strange rib circle, and after having had corresponding angle, the deviation from cylindrical form of antithesis rib circle is measured same responsive.
During measurement, tested part is placed on and supports between pin 4 and the survey head of survey table 1, rotate tested part one to enclose, read the number of oscillations surveying table indicator, thus judge the cylindricity rib number of tested part, unclamp adjustment screw 2 again, adjust according to the corresponding angle listed by table 1, again adjustment screw 2 is tightened, and adjust survey table 1 and make it show in suitable scope and be fixed, the measuring point of tested part is rotated a circle, survey the difference of the scale range on table, namely it is observed value, again this value is revised according to the scale-up factor of table 1, the actual value of deviation from cylindrical form can be obtained.
A kind of deviation from cylindrical form measuring apparatus of the utility model, utilizes cursor principle, the position of adjustment gauge stand, meets the measurement of the deviation from cylindrical form of strange rib circle, the even rib each form of circle; Change survey table into fax sensor, it is possible to the error waveform at the record tested position of part, and rotate the number of peak or the paddy formed for one week from tested part, accurately determine the rib number of part tested position cylindricity; Use the optimizational function of engineering software, analyzed the angle value scale-up factor that different rib number is corresponding so that three point method measuring method range of application has increased, and the corresponding raising of sensitivity; In addition, this apparatus structure is simple, and cost is low, is easy to promote.
