CLAMPING DEVICE FOR SPLIT CONNECTION OF TWO SHAPED ARTICLES Russian patent published in 2001 - IPC

FIELD: mechanical engineering; split joints. SUBSTANCE: proposed clamping device for split connection of two shaped articles first of which is made for fitting in and locking of core 1 is provided with axially movable pusher 7, two clamping elements with clamping hook made for fitting in, at least partially, in hole of second shaped article for creating clamping pressure in part of second shaped article which partially closes the hole. Fitted-in core has turning device, first system of sliding surfaces for axial travel of pusher and second system of sliding surfaces for cross travel of both clamping elements at their axial displacement. Each clamping element has elongated flat part one end of which is made in form of hook in wide cross-section, and other end, in form articulated hooks. Pusher has flat end part with two holes for receiving articulated hooks of clamping elements to form clamping element by means of articulated hooks and hole. Pusher and both clamping elements are provided with complementary devices for holding clamping element with possibility of their turning around axis passing in parallel with wide direction of corresponding elongated part. EFFECT: reduced overall dimensions, increased reliability. 10 cl, 30 dwg
