Definitions

  • the ejection pin preferably has a non-circular or cam-shaped section and is arranged with respect to the base of the associated recess of the tool holder in such a way that the tool holder is ejected from the base holder by rotating the ejection pin with the aid of the radially outer region of the flattening can.
  • the interacting surfaces of at least one clamping shoulder and a pair of clamping claws are at least partially beveled, so that when the clamping pieces are radially expanded, an axial pull is simultaneously exerted on the tool holder.
  • Fig. 3 corresponds to Fig. 2, but shows the contracted

Abstract

Un dispositif de serrage utile pour accoupler des dispositifs de support ou des broches de machines avec des outils ou des porte-outils d'usinage par enlèvement de copeaux comprend deux tendeurs écartables (22, 24) qui accrochent par derrière des épaulements de serrage (20, 22), situés à l'intérieur de la broche de la machine et du porte-outil (12), avec des griffes de serrage (32, 40) qui font radialement saillie vers l'extérieur. Deux tendeurs (22, 24) sont mutuellement reliés dans leur partie médiane au moyen d'un organe d'écartement (26), formant un bloc de serrage. Le bloc de serrage présente, à l'état serré, un diamètre extérieur inférieur au plus petit diamètre intérieur aussi bien de la broche de la machine que du porte-outils.
