Abstract
The invention relates to a collet device, in particular for snap closure attachments for gaseous and/or liquid media which comprises a clamping plunger and a plurality of collets each with a connection end and a bearing end. The bearing ends of the collets are detachably suspended on the clamping plunger and the collets can be displaced axially with the clamping plunger using an actuating member. For simple and rapid replacement and assembly of the collets the invention proposes that the collet arrangement is linked to a fixing member movable in relation to the collet arrangement in order to block the bearing ends positively.
Claims27
A spring chuck device, comprising:
- a tension piston;
- and
- several spring chucks, the spring chucks each having a connection end and a bearing end, being secured detachably with their bearing ends to the tension piston and being axially adjustable together with the tension piston by means of an actuation element, wherein the tension piston and the spring chucks form a spring chuck arrangement which is coupled to a moveable fixing element relative to the spring chuck arrangement for catching the bearing ends in an interlocking manner, said fixing element having a front side.
A method for connecting couplings for a fluidic media, comprising the steps of:
- providing a spring chuck device comprising a tension piston and several spring chucks;
- securing the spring chucks at bearing ends to the tension piston;
- releasably coupling a movable fixing element to the tension piston and the spring chucks, said fixing element catching the bearing ends in an interlocking manner;
- and
- axially adjusting the tension piston by means of an actuation element, so that the spring chucks at a connection end cause a change in a perimeter of the connection end.
