MODULES JOINING APPARATUS Russian patent published in 2006 - IPC B23B29/00 B23C5/26 

FIELD: processes for working in program control machine tools, tool modular systems.

SUBSTANCE: apparatus includes main and addition modules. The last has stem and supporting end. Main module has inner mounting surface and reciprocal end, locking member and collet chuck with inner and outer surfaces. Said chuck is arranged between stem and inner mounting surface of main module with possibility of engaging with it. In order to simplify design, to increase rigidity and strength of joining, collet chuck includes central rigid part having at least one seat for engaging with locking member and two end parts having radial elastic members joined with central rigid part through axial elastic members. Collet chuck members elastic in radial direction may have at least one axial slit on end portion of each part. Members of collet chuck elastic in axial direction may be in the form of bridges formed by two pairs of radially opposite slits arranged in staggered fashion in such a way that one pair of slits is shifted relative to other along axis of collet chuck. Inner mounting surface of main module may be cylindrical; collet chuck may have cone inner mounting surface.

EFFECT: simplified design, increased rigidity and strength of joining.
