Definitions
- the present invention relates to a fluid-operated drive, in particular a pull and push drive, according to the preamble of claim 1.
- a piston rod is completely dispensed with.
- the power transmission from there and back reciprocatingly driven piston to be moved G is carried out e-subject matter by means of a coupling part, which is connected directly to the piston and passes outside through a slot in the cylinder jacket to.
- a coupling part which is connected directly to the piston and passes outside through a slot in the cylinder jacket to.
- complex measures must be taken to seal the cylinder along the slot and to prevent foreign particles such as dirt from entering the cylinder.
- this solution has the disadvantage that the movement of the coupling part is limited to the area of the cylinder and, moreover, can only take place in the longitudinal axis of the cylinder. The piston movement can therefore not be transmitted to any location away from the cylinder without additional precautions.
- a cable that can be coupled to the object to be moved is used instead of the piston rod, which cable is fastened to the piston on opposite sides thereof and is guided outwards through the cylinder heads.
- the power transmission from the piston to the object to be moved takes place through the section of the cable which is subjected to tension. It is possible to restrict the installation length essentially to the length of the cylinder-piston unit and still transmit the movement of the piston directly to any location, but it is necessary for guiding the cable from one side of the piston to the coupling point with the object to be moved and from this coupling point back to the other side of the piston a certain amount of construction and space is required.
- pulleys for the cable and seals for the Sealing the passage point of the cable can be provided.
- the present invention is based on the object of providing a drive of the type mentioned at the outset which, with a simple construction and the smallest possible space requirement, enables the piston movement to be transmitted in the shortest possible way to any location detached from the cylinder-piston unit.
- the piston rod can be spatially guided in connection with the cylinder itself, which allows a movement transfer along a suitable path to any desired location with little space requirement and without difficulty.
- the guide extending into the interior of the cylinder prevents the piston rod from buckling under its pressure load.
- a double-acting cylinder-piston unit is preferably used, which allows a force effect in both directions of movement of the piston.
- the piston rod is formed by a ball-and-socket link chain, both tensile and compressive forces can be correctly transmitted with each spatial guidance of the piston rod.
- a particularly simple and compact design results if the section of the piston rod guide running inside the cylinder is formed at least over part of its length by the bolts connecting the cylinder heads to one another.
- these bolts can also be assigned the further task of directing the piston rod in the cylinder.
- the drive shown in FIGS. 1-3 in perspective and in different sectional views has a pneumati cal cylinder-piston unit 1.
- a hydraulic cylinder-piston unit can also be used.
- the cylinder 2 of the cylinder-piston unit 1 is formed in a manner known per se by a cylinder jacket 3 and two cylinder heads 4 and 5.
- the two cylinder heads 4 and 5 are braced against each other by means of clamping bolts 6.
- the clamping bolts 6 run inside the cylinder 2.
- Each clamping bolt has a thread at its two ends 6a and 6b. With the end 6a, the clamping bolts are screwed into the cylinder head 5.
- a piston 10 Arranged in the interior of the cylinder 2 is a piston 10, which is driven in a known manner to and fro in the axial direction of the cylinder 2.
- a flexible, movable piston rod 11 is connected to the piston 10.
- This piston rod 11 is formed by a ball joint link chain, which is of a type known per se.
- the individual links 12 of the ball joint link chain are connected to one another by means of ball joints, which move the space enable possibility.
- the piston rod is provided with a connecting link 13 to which the first link 12 ′ of the ball joint link chain 11 is connected.
- the clamping bolts 6 are arranged distributed around the circumference of the ball joint link chain 11 and thus form a straight guide for the ball joint link chain 11.
- the ball joint link chain 11 is guided outside the cylinder-piston unit 1 through a guide tube 14, which runs spatially in the desired manner which can be selected as desired, as can be seen from FIG. 1.
- the guide formed by the tensioning bolts 6 and the guide tube 14 prevents the ball joint link chain 11 from buckling and ensures that the link chain 11 can move back and forth along the desired movement path.
- the guide tube 14 is connected to an extension 5a of the cylinder head 5 in a manner known per se for tube connection.
- a union nut 15 is screwed onto this extension 5a, which interacts with a cutting and wedge ring 16.
- the guide tube 14 is in contact with a support ring 17, which in turn is supported on a retaining ring 18 (circlip) which is embedded in the extension 5a.
- This locking ring 18 serves to secure the position of a sealing bush 19 which is in contact with the sealing ring 18 via a further bearing ring 20.
- the guide tube 14 is ver with a longitudinal slot 21 extending in its longitudinal direction see through which extends a coupling element 22 which is attached to the front end of the ball joint link chain 11.
- the drive is drive-connected to the object to be moved via this coupling element 22.
- Each cylinder head 4 or 5 is provided with a feed channel 23 or 24 (FIGS. 2 and 3) for a pressure medium, which in the present case is for compressed air.
- a feed channel 23 or 24 is connected to a connection, as is shown in FIG. 3 with the connection 25.
- These connections can be connected to a compressed air source via a switching valve.
- This drive has the advantage that the object to be moved can not only be moved back and forth in the extension of the axis of the cylinder 2, but also along an arbitrary spatial path. Since it is possible because of the mobility of the piston rod 11, the guide tube 14 immediately after the cylinder Carry away piston unit 1 in any direction, the required installation length may be limited to a level that is only slightly greater than the length of the Z y Linders 2. Since, as already mentioned, the profile of the guide tube 14 can be selected arbitrarily in space , any obstacles can be avoided without difficulty.
- the longitudinal slot 21 in the guide tube 14 extends close to the cylinder-piston unit 1, there is a risk that foreign particles which have penetrated into the guide tube 14 through this longitudinal slot 21 can get between the chain links 12 and then into the interior of the cylinder 2.
- this longitudinal slot 21 can be covered, for example.
- the variant shown in FIG. 5 corresponds to the exemplary embodiment according to FIGS. 1-4.
- the piston rod 11 can be formed by a flexible tube that can be filled with a gaseous or liquid, pressurized medium for reinforcement.
- the piston rod can also be replaced by a flexible rod, e.g. made of plastic, a cable, a wire rope or the like.
- the drive described can find a wide variety of applications. For example, it is conceivable to use this drive to operate flaps and windows and curtains, e.g. Theater curtains on round stages, open and close. Furthermore, this drive can also be used to move the ejection element back and forth in the stacking device described in DE-OS 28.42.116 or the corresponding US Pat. No. 4,229,134.
