DEVICE FOR PLUG-IN CONNECTION OF TWO PARTS Russian patent published in 2011 - IPC B23C5/26 B23B31/107 

FIELD: process engineering.

SUBSTANCE: proposed device for connecting two parts with set pin arranged on first part with, in fact, cylindrical lateral surface and radially extending annular flat surface that confines mount pin at its base, with receiving bush arranged on second part, having cylindrical inner surface and confined by annular face surface, and with clamping mechanism to pull mount pin into receiving bush and press flat surface and face surface together. Note here that receiving bush has inner taper part diverging from cylindrical inner surface toward face surface. Note also that mount pin has mating outer taper surface. Mind that centring ring is fitted at mount pin base, said ring comprising outer taper part and, at least, partially straining elastically. Said centring ring has circular bearing part connected with mount pin by geometrical of force closure, and circular spring part adjoining axially said bearing part that extends free beyond cylindrical lateral surface of mount pin and comprises outer taper part.

EFFECT: precise joint due to better centring.
