<p>#CMT# #/CMT# A releasing piston (5) in a piston chamber (3) acts on a tightening piece (4). A tension spring (7) in a spring holder (6) acts on the releasing piston. Activated by the tightening piece, collet pincers (9) in segments have pincer jaws (10). In a guide holder (13) for the tightening piece co-axially oriented towards the axle (12) of a chuck body (2) there is a sealing cover (14) to be adjusted on-axis. #CMT#USE : #/CMT# Chuck head for tools. #CMT#ADVANTAGE : #/CMT# This chuck head is simple to operate with improved safety in tightening. The sealing cover is influenced by the force of a spring (15) supported directly or indirectly on the tightening piece. A covering head (17) blocks the pincer jaws in an open position when the collet pincers in segments are in a releasing position. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a longitudinal cross-section of a chuck head with its top half open and its bottom half tightened. 2 : Chuck body 3 : Piston chamber 4 : Tightening piece 5 : Releasing position 6 : Spring holder 7 : Tension spring 9 : Collet pincers 10 : Pincer jaws 12 : Axle of chuck body 13 : Guide holder 14 : Sealing cover 15 : Spring 17 : Covering head.</p> |
