Abstract
A linear-drive cylinder actuated by a pull means or by a pressure medium has a cylinder tube, in which a piston is guided axially displaceably. The movement of the piston is guided outward via force-transmission means. The cylinder tube is closed on the end face by means of a closing plug. Both the cylinder tube and the closing plug each have a transverse bore. A fastening means, such as, for example, a holding tube or a bolt, passes through the mutually aligned transverse bores, so that the closing plug is secured axially in the cylinder tube.
Claims29
A linear-drive cylinder, comprising:
- a cylinder tube having a longitudinal slot, a longitudinal direction and a bore transverse to the longitudinal direction, the bore having a longitudinal length;
- a piston mounted in the cylinder tube and displaceable in the longitudinal direction;
- a web connected to the piston that passes through the longitudinal slot;
- a closure which closes an end of the cylinder tube and which projects with at least one portion into the cylinder tube;
- and
- fastening means for fastening the closure to the cylinder tube,the fastening means including at least one holding tube with a locking device;
- wherein the closure includes a closing plug which is introduced into the cylinder tube, the closing plug including at least one transverse bore coaxial with the bore in the cylinder tube, the transverse bore being a through-bore with a longitudinal length extending entirely through the closing plug;
- and
- wherein the at least one holding tube extends transversely to the longitudinal direction of the cylinder tube into and for the entire longitudinal length of each of the transverse bore of the closing plug and the bore of the cylinder tube so that the locking device engages with the cylinder tube.
