Abstract
The utility model provides a caliper rule for measuring the radiuses of inner and outer arcs and a spherical surface, which comprises a fixed chord length caliper and an adjustable cambered surface chord height ruler, and wherein, the adjustable cambered surface chord height ruler, the height of which can be adjusted, is arranged at the center of the fixed chord length caliper. The caliper rule is characterized by simple structure, convenient and rapid operation, high measurement precision, etc.
Description
Technical field
The utility model relates to a kind of survey instrument, relates in particular to a kind of inside and outside circular arc and spherical radius and measures slide calliper rule.
Background technology
At present to the measurement of the radius size of the inside and outside circular arc of incomplete part that damages and sphere, adopt the chord length of measuring arc, action value usually again by calculating.Owing to limit by survey instrument and measurement means, deviation often appears in the chord length that records, action data and physical size, influences final radius calculation result's accuracy, influences the part mapping.
Summary of the invention
The purpose of this utility model just provides a kind of inside and outside circular arc and spherical radius is measured slide calliper rule, and these slide calliper rule also calculate by the cambered surface action of measuring the definite value chord length, accurately draw the radius distance value of inside and outside circular arc and sphere.
The purpose of this utility model can realize by following scheme: comprise a definite value chord length card and an adjustable cambered surface action chi, described adjustable cambered surface action chi is located at the center of definite value chord length card, its adjustable height.
The beneficial effects of the utility model are: it is simple in structure, convenient to operation to measure slide calliper rule, the measuring accuracy height.
Description of drawings
Fig. 1, the utility model structural representation.
Embodiment
Contrast Fig. 1 as can be known, the utility model comprises a definite value chord length card 1 and an adjustable cambered surface action chi 2, and described adjustable cambered surface action chi 2 is located at the center of definite value chord length card 1, its adjustable height.
Principle of work of the present utility model is as follows: definite value chord length card of the present utility model is placed on the arc surface, by regulating cambered surface action chi, the bottom of the two ends of definite value chord length card and adjustable cambered surface action chi is on the same cambered surface gets final product.Again according to formula R=H
2+ (L/2)
2/ 2H (R: tested part radius.H: actual measurement action.L: the definite value chord length) can calculate the radius of the circular arc of surveying.
