The Application and the Calculation of Deflection Angle of the Adjustable Modular Fixture Which Has Space Double Angle

Abstract

The basic principle and procedure which is using the stereoscopic geometry, spherical surface method and projection method to solving the spatial bidirectional deflection angle are described in this paper. Respectively, it is using the above three methods to solve the positioning deflection angle of the space double angle in the adjustable modular fixture, through the typical examples, it calculates the positioning angle and the orientation angle of different kinds of parts which are positioning in the modular fixture; It is also to design a set of modular fixture which is suitable for space double angle with drilling and milling jig, the other is suitable for rotary space angle with milling modular fixture, there are suitable for all kinds of parts that can adjusting the space double angle, it is solving the positioning and clamping problems of the similar parts in the processing and it is satisfied to the requirement of NC machining.
