Definitions

  • the invention relates to a housing for a working cylinder, with a cylinder tube, which consists of an inner tube and a coaxially arranged outer tube enclosing the inner tube radially on the outside with direct contact, the inner tube being a metal tube and the outer tube being a plastic tube.
  • Such a housing is disclosed in US-A-4 884 493. Its strength is determined by the outer tube, which is made of a composite fiber material and comprises a plurality of tortuous fibers. Since the material is relatively porous, there is an inner tube made of metal inside the outer tube, which ensures the necessary fluid tightness.
  • the fiber structure of the outer tube allows high strength with a low weight, but is associated with a relatively complex and therefore cost-intensive production method.
  • the inner tube seems to have little influence on the strength to take and, apart from the sealing function, only to act as a carrier for the fiber material.
  • plastic tube forming the outer tube consists of unreinforced plastic material.
  • the inner surface of the cylinder tube forming the running area for the piston continues to be made of extremely wear-resistant and true-to-shape material, which can also be within the necessary roughness depths without any problems Lets hold values.
  • the metal tube forming the inner surface is also largely responsible for the strength of the housing.
  • plastic material for the enveloping outer tube, it is therefore possible to use plastic material of lower strength, particularly since it is not exposed to dynamic loads and therefore no high demands have to be made of the abrasion resistance.
  • the use of plastic material for the outer tube enables a diverse contouring of the outer circumference with little effort, so that, for example, fastening grooves for sensors can be provided without problems.
  • the inner tube and / or the outer tube of the cylinder tube are expediently designed as extruded parts, with which any contours can be realized without problems.
  • the housing also expediently has cylinder covers arranged on the end face of the cylinder tube, which consist entirely of plastic material, which can also be an unreinforced plastic.
  • the connection to the cylinder tube is made directly between the cylinder cover and the outer tube, and in addition to a snap or snap connection or a welded connection, at least one cylinder cover can in particular also be formed in one piece with the outer tube. This results in a housing with a very small number of components, and any fastening part that may be necessary to fix the housing can be molded directly onto one of the cylinder covers made of plastic material.
  • a particularly pneumatically actuated cylinder 1 is shown, in which a first design of a housing 2 is realized.
  • the latter has a cylinder tube 3 with, for example, a circular cross-sectional contour, which is closed at both ends by a cylinder cover 4, 5.
  • the housing space 6 delimited by the cylinder tube 3 and the two cylinder covers 4, 5 is suitable for the axially displaceable receiving of a piston 7, which is provided with a piston rod 8, for example.
  • the latter extends from the piston 7 coaxially through the housing space 6 towards one of the Cylinder cover 4, which has a feed-through opening 9 through which the piston rod 8 projects outwards.
  • a schematically indicated guide and / or seal arrangement 13 is expediently used in the latter.
  • connection opening 16 opens into the working chamber 14, as is also the case for a connection opening 17 in the first cylinder cover 4 with respect to the working chamber 15.
  • the connection openings 16, 17 allow the connection of suitable connecting lines in order to supply or discharge pressure medium and thereby move the piston 7 with its piston rod 8 back and forth in the direction of the housing longitudinal axis 18.
  • the cylinder tube 3 is composed of two tube elements, namely an inner tube 23 and one in the area of its outer lateral surface directly Contact tightly enclosing outer tube 24.
  • Outer tube 24 and inner tube 23 are accordingly arranged coaxially and concentrically with each other.
  • the inner tube 23 consists of metal with high abrasion resistance, with stainless steel or stainless steel being used as the material in the exemplary embodiment. This material also allows the maintenance of very small wall thicknesses without having to suffer from strength disadvantages.
  • the metal tube 26 thus present can be produced with relatively little effort, very true to size and with extremely small tolerances, and the inner surface 25 swept by the piston 7 during its movement can also be machined very precisely and equipped with an extremely low surface roughness, so that it runs more smoothly and with less wear Run of the piston 7 is guaranteed.
  • the inner tube 23 designed as a metal tube 26 is preferably an extruded part cut to the desired length, which can have the desired final shape directly during manufacture by means of suitable calibration measures. If required, however, it is easily possible to connect fine reworking with regard to the inner surface 25, for example by honing.
  • the inner tube 23 is enclosed by the outer tube 24 over its entire axial length, both tubes are preferably of the same length, so that they end flush with one another.
  • the outer tube 24 is a plastic tube 27, which consists of preferably unreinforced plastic material, which is relatively inexpensive. Reinforcement is not necessary since the strength of the cylinder tube 3 is largely determined by the metal tube 26. Nevertheless, the outer tube 24 will also be included in the strength function in order to make the overall wall thickness of the cylinder tube 3 as small as possible.
  • the outer tube 24 is also preferably an extruded part or an extruded part cut to the desired length, the requirements for dimensional accuracy being lower, since it does not perform a guiding function with respect to the piston 7. In the normal case, the proportion of wall thickness of the cylinder tube 3 which is due to the outer tube will be greater than that which is due to the metallic inner tube 23.
  • the outer tube 24 and the inner tube 23 touch directly with the mutually facing peripheral surfaces.
  • the two tubes 23, 24 are fixed relative to one another both in the circumferential direction and in the axial direction. This is achieved, for example, by measures which bring about radial bracing between the tubes 23, 24 which are pulled onto one another.
  • the inner tube 23 and outer tube 24 can in principle be axially pressed into one another in the cold state.
  • the relative hold is preferably ensured by a so-called shrink fit, which is the case in the exemplary embodiment.
  • the outer tube 24 and the inner tube 23 are initially in a separate state, the inner diameter of the plastic tube 27 provided as the outer tube 24 being somewhat smaller than the outer diameter of the metal tube provided as the inner tube.
  • the plastic tube 27 is then heated until an expansion is achieved which allows the metal tube 26 to be inserted without problems.
  • total tolerances of approximately 0.5 mm are bridged between the outer diameter of the metal tube 26 and the inner diameter of the plastic tube 27.
  • plastic material of the plastic tube 27 is polyoxymethylene (POM)
  • POM polyoxymethylene
  • heating to 160 ° C can result in an expansion of approximately 0.6 mm if one assumes a nominal cylinder tube diameter between 32 and 40 mm , so that assembly is possible without effort.
  • the tolerances to be bridged can also be lower for other plastic materials.
  • the outer tube is made from polyvinyl chloride (PVC).
  • PVC polyvinyl chloride
  • the inner tube 23 is cooled by the latter after the outer tube 24 has been pushed on clasped tightly or spanned.
  • both cylinder covers 4, 5 are also made of plastic.
  • both cylinder covers 4, 5 are plastic parts made of, in particular, unreinforced plastic material. The latter suitably corresponds to that used for the associated outer tube 24. So that no complex connection measures that increase the overall width and / or the weight are required, it is advantageous here if the connection between a respective cylinder cover 4, 5 and the cylinder tube 3 is a permanent connection, as in the exemplary embodiment.
  • a snap connection 28 is located between the cylinder cover 4 on the right in FIG. 1 and the cylinder tube 3 in front.
  • a hollow cylindrical extension 29 of the cylinder cover 4 is placed coaxially on the outer tube 24 and engages in a complementary circumferential groove 34 of the outer tube 24 with a radially inward protruding, in particular circumferential locking projection 33.
  • a radially outwardly projecting ring projection of the outer tube 24 can also engage in a corresponding locking recess on the inner circumference of the extension 29.
  • the outer tube 24 which is made of plastic, acts as the connection partner of the cylinder tube 3.
  • a welded connection 35 more precisely: a friction welded connection.
  • the cylinder tube 3 with the corresponding axial end region 36 is inserted into a sleeve-like extension 29 'of the cylinder cover 5, and it can additionally be immersed in an annular axial recess 37 of the cover part adjoining the extension 29'.
  • the end face 38 of the outer tube 24 is advantageously beveled in the manner of a circumferential bevel and bears against a complementary inclined surface 39 at the base of the axial recess 37.
  • the bevel is practically the circumferential one Broken outer edge of the outer tube 24, and there is a larger contact area in terms of amount compared to blunt contact. This is important for the welding process, since the friction welding connection 35 is present in the contact area between the end face 38 and the inclined surface 39.
  • a cylinder cover 5 'and the plastic tube 27 form a one-piece structural unit, in that they were produced as a single component, in particular as part of a plastic injection molding process.
  • the internal assembly of the metal tube 26 can be done in a manner as has already been explained with reference to FIG. 1.
  • the metal tube 26 should consist of non-magnetizable and non-magnetic material, as is the case for the stainless steel used in the example.
  • a fastening groove 42 is provided on the outer circumference, that is to say in the area of the outer lateral surface 41 of the outer tube 24, which extends in the direction of the longitudinal axis 18 of the housing and is formed in one piece with the outer tube 24 and serves to releasably hold a sensor 43 indicated by dash-dotted lines .
  • the fastening groove 42 is, for example, embedded in a rib-like tubular projection 44 which is radially raised in the circumferential direction of adjacent regions of the lateral surface 41 and extends in the longitudinal direction of the outer tube 24.
  • the fastening groove 42 is designed as a dovetail groove, but can also be contoured differently, for example as a T-groove.
  • the axial length of the fastening groove 42 and the pipe protrusion 44 which may be present can correspond to that of the outer pipe 24 or is designed for the entire housing design in such a way that it extends only to the beginning of the extensions 29, 29 ', possibly attached cylinder cover 4, 5. It goes without saying that further, parallel fastening grooves 42 can be provided distributed over the circumference of the outer tube 24. With a corresponding wall thickness of the outer tube 24, the fastening groove 42 can be inserted directly into the wall of the outer tube 24 without an additional radial projection.
  • a fastening part 47 is also integrally formed on at least one of the cylinder covers 5,5 ', which makes it possible to fix the housing 2 at the place of use on a component provided for this purpose.
  • the attachment part is e.g. an eye and / or an external thread.
