Description
Technical field
The utility model relates to measuring equipment design field, specifically with the sine gauge clamped and mark.
Background technology
Sine gauge is the measurement instrument for precision measurement taper tolerance according to sine principle design.The principle that taper tolerance measured by sine gauge is based on the sine function utilizing right-angle triangle.Sine gauge utilizes sine to define the gauge taken measurement of an angle with tapering etc., also claims sine protractor.It forms primarily of the steel right cylinder of a steel rectangular parallelepiped with two same diameter being fixed on its two ends, and by one, steel rectangular parallelepiped and two precision cylinders form sine protractor accurately.The diameter of two cylinders is identical, and their centre distance requires very accurate, generally has 100mm and 200mm two kinds.
Under normal circumstances, the public tangent plane of workplace and bottom two equal diameter cylinders of sine gauge is parallel, this sine gauge is also provided with front apron and side shield and is used for gear by laying measured workpiece.By the difference of face width B, it is divided into wide type and narrow two kinds.There are 100mm and 200mm two kinds of specifications in two cylindrical center apart from L.Sine gauge is mainly used in the coning angle measuring low-angle and outer cone.Need and gauge block with the use of, be placed on flat board, use dial gauge reading.Sine gauge utilizes the sine function relation of right-angle triangle to carry out measuring.According to the nominal cone angle alpha of tested circular cone and the centre distance L of sine gauge cylinder during measurement, be calculated as follows out the size h:h=L*sin α of gauge block, the gauge block group pad combined by h value is below the cylinder of sine gauge one end, if the actual coning angle of tested circular cone equals α, then the upper plain line of this circular cone must be parallel with plate work face, namely indicating gauge is identical in the indicating value of a, the b 2 at upper plain line two ends, otherwise indicating gauge is just not identical in the indicating value of a, b 2, is respectively M
awith M
b, at this moment, the difference (M of a, b 2 readings
a-M
b) can measure with ruler or vernier caliper with the distance l(of a, b point-to-point transmission) and ratio be taper tolerance Δ c, and take into account sign symbol:
Δc= （M
a-M
b）/l
Taper tolerance is multiplied by radian to after the reduction coefficient of second, can try to achieve coning angle deviation.
In testing process, a, b two measurement points indicate without any vestige, entirely with follow-up memory and experience, measure the distance l of a, b point-to-point transmission with ruler or vernier caliper, and such error is large, and result is inaccurate; In addition, sine gauge workplace tilts, workpiece deviation of gravity center, and cause work piece unstable, plain line and the sine gauge workplace of measured workpiece can not be fitted completely, cause testing result serious distortion.
