Abstract

The invention relates to a tool and method for detecting the starting angle of a spiral groove of a spiral internal spline housing, solves the problems of low efficiency and high cost in the prior art, and can simply and quickly detect the starting angle of the spiral groove of the internal spiral spline housing by directly detecting the angle of the axis of a two-dimensional plane cylinder of an auxiliary tool; and a general measuring instrument with a coordinate measuring function can be directly adopted for measurement.

Description

technical field [0001] The invention belongs to the technical field of spline measurement, in particular to a detection tool and a detection method for the initial angle of the helical groove of a spiral inner spline sleeve. Background technique [0002] A helical inner spline sleeve composed of inner helical grooves is a common part in mechanical structures. The central helical surface of the helical groove of the part has a certain starting angle requirement relative to the part datum. [0003] For the helical inner spline sleeve composed of inner helical grooves, the central helical surface of the helical groove only exists in theory, and there is no actual material entity that can be touched, so the initial positioning angle of the central helical surface cannot be directly measured by measuring instruments; Since the central helical surface is a three-dimensional curved surface in space, when measuring in the prior art, first use complex mathematical methods to deduce ...
