Definitions

  • the invention relates to a pressure-operated cylinder according to the genus specified in the preamble of claim 1.
  • Such a pressure medium-actuated working cylinder is already known from DE 37 06 952 A1, in which a directional control valve which controls the working cylinder can be mounted on a flange plate which is arranged on two parallel, adjacent tie rods of this working cylinder.
  • the two tie rods penetrating the flange plate are made hollow from the four tie rods and used as pressure medium channels, via which the pressure medium controlled by the directional control valve is guided into the two pressure chambers on both sides of the piston.
  • the disadvantage of this working cylinder is that pressure medium channels are guided externally from the actual cylinder tube and transfer openings for the pressure medium from the hollow tie rod must be provided in the cover area, an additional receiving plate being required compared to the cylinder cover.
  • the cylinder therefore needs relatively Many components and also results in a large number of sealing points, the transition points from the tie rods loaded with high forces into the cylinder covers being particularly critical. The cylinder therefore builds relatively complex, with the risk of leakage being relatively large.
  • a pressure medium actuated working cylinder in which the cylinder tube installed between two cylinder covers is designed as a profile tube with external channels, which can be used with the aid of additional components for different functions, such as pressure medium-carrying circulation channels or fastening channels.
  • the disadvantage of this working cylinder is that the outer channels must have a longitudinal slot over their entire length, so that profiled components can be installed depending on the corresponding function. This leads to high construction costs and a risk of leakage. It is also unfavorable that when an external channel is used as the pressure medium channel, a seal or pressure medium connection has to be established via the front cylinder cover, which also increases the number of pressure medium-carrying components. For the rest, no information is given here on the attachment of a flange plate with directional control valve.
  • the pressure cylinder-actuated working cylinder according to the invention with the characterizing features of the main claim has the advantage that it allows a compact unit with integrated pressure medium channels, the risk of leakage pressure medium is particularly reduced.
  • the working cylinder needs fewer components, especially those with pressurization.
  • the working cylinder is easy to handle and versatile. It can be produced in a space-saving and thus inexpensive manner.
  • a construction according to claim 2 is particularly favorable, as a result of which a relatively simple and inexpensive profile tube can be used for the working cylinder. It is also advantageous if the working cylinder is designed according to claim 3, so that the longitudinal struts can also take over the function of tie rods if necessary. Furthermore, it is advantageous if the working cylinder is designed according to claims 4 and 9, as a result of which the flange plate can be guided and held properly. In addition, it is advantageous if the connections for inlet and return are formed directly on the flange plate. Further advantageous configurations result from the remaining claims, the description and the drawing.
  • FIG. 1 shows a perspective illustration of the working cylinder which can be actuated by pressure medium in a simplified manner
  • FIG. 2 shows a front view of the working cylinder according to FIG. 1 partly in longitudinal section
  • FIG. 3 shows a top view of the working cylinder according to FIG. 2
  • FIG. 4 shows a side view according to A in FIG. 2.
  • FIG. 1 shows a perspective, schematic illustration of a pressure cylinder that can be actuated by pressure medium, for the explanation of which reference is also made to FIGS. 2 to 4.
  • the working cylinder 10 has, as a housing, an essentially tubular cylinder liner 11, on the outside of which a flange plate 12 is attached, which in turn carries a flanged directional valve 13.
  • the cylinder liner 11 has a continuous guide bore 14 in which a piston 15 is guided so as to be axially displaceable.
  • a piston rod 16 is fastened to the piston 15, which is guided tightly and slidably in a first, front cylinder cover 17 and projects through the latter through to the outside.
  • the first cylinder cover 17 is inserted on the piston rod side into the guide bore 14 of the cylinder liner 11 and is axially fastened there and, together with the piston 15, delimits a first, front pressure chamber 18.
  • FIG. 1 shows particularly clearly in connection with FIG. 4, the tubular cylinder sleeve 11 has on its outer surface four longitudinal struts 22 to 25 running parallel to the longitudinal axis, of which the two Longitudinal struts 22, 23 are used as guide elements for the flange plate 12.
  • the longitudinal struts 22 to 25 are arranged evenly distributed on the outer circumference of the cylinder liner 11, so that, seen in cross section through the cylinder liner 11, they lie on the corners of a square.
  • the longitudinal struts 22 to 25 are each integrally formed in the manner of profile rails on the outer surface of the cylinder liner 11, so that the cylinder liner 11 can be easily produced from a profile tube.
  • the outer surface of the cylinder liner 11 is seen in cross section essentially as an octagon, in which the vertically and horizontally lying four longitudinal surfaces 26 continuously and evenly, while the longitudinal struts 22 to 25 are integrally formed on the four obliquely lying longitudinal surfaces 27.
  • Each of these longitudinal struts 22 to 25 forms an approximately semicircular guide surface 28 towards the outside, each of which merges into the oblique longitudinal surface 27 via two guide surfaces 29, 31 running approximately parallel to one another.
  • Each of the longitudinal struts 22 to 25, which extend over the entire length of the cylinder liner 11, has a continuous longitudinal bore 32.
  • the two axial end regions of each longitudinal bore 32 have blind bore-like threaded bores 33, 34 which are introduced into them at the end face and run in the axial direction.
  • sealing plugs 35 are screwed into the threaded bores 33 and 34, respectively, from the respective end faces, so that the longitudinal bore 32 in the first longitudinal strut 22 forms a first pressure medium channel 36.
  • This first pressure medium channel 36 is connected to the second pressure chamber 21 via a first oblique bore 37 arranged in the cylinder bushing 11.
  • a second pressure medium channel 38 is formed in the second longitudinal strut 23, which is connected to the first, front pressure chamber 18 via a second oblique bore 39, which lies in the region of the first cylinder cover 17.
  • the two oblique bores 37, 39 can be easily produced in the profiled cylinder liner 11 and form so-called transition openings to the two pressure chambers on both sides of the piston 15.
  • the flange plate 12 has on its underside two mounting grooves 41, 42 which are open on one side and whose shape is precisely adapted to the outer contour of the longitudinal struts 21, 22, so that the flange plate 12 can be moved smoothly and axially is guided on the longitudinal struts 21, 22.
  • the flange plate 12 is pushed from an end face of the cylinder liner 11 onto the longitudinal struts 22, 23 and locked in a predetermined position by locking screws 43.
  • the center planes of the two mounting grooves 41, 42 are perpendicular to one another, so that the flange plate 12 engages behind the longitudinal struts 22, 23 and is thus held captively on the cylinder sleeve 11 in the radial direction.
  • the flange plate 12 In the locked position, the flange plate 12 has such a position that the first Pressure medium channel 36 in the longitudinal strut 22 via a first transition opening 44 (FIG. 2) and transverse channels 45 running in the flange plate 12 has a connection to a first motor connection 46 in a flange surface 47.
  • a pump pressure connection 52 located in the flange surface 47 between the two motor connections 46, 48 is connected to an inlet connection 53, which is formed in a rear end face 54 of the flange plate 12.
  • an angle connection 55 is additionally screwed into this inlet connection 53, which is not shown in FIG. 1 for the sake of simplicity.
  • two return connections 56, 57 are arranged in the flange surface 47, of which, for the sake of simplicity, only the connection from the return connection 56 to an outlet connection 58 located in the side wall of the flange plate 12 is shown in FIG.
  • FIG. 3 in particular shows in more detail, there are also two outlet connections corresponding to the two return connections 56, 57, into each of which an exhaust air cap 59 is screwed.
  • the two transfer openings 44, 51 between the flange plate 12 and the two longitudinal struts 22, 23 on the cylinder liner 11 are sealed by suitable seals, so that no pressure medium can leak to the outside at the transition of the pressure medium channels from the flange plate 12 into the cylinder liner 11.
  • FIGS. 1 and 2 The mode of operation of the working cylinder 10 is explained as follows, reference being made primarily to FIGS. 1 and 2:
  • FIG. 1 the course of the pressure medium flow is indicated in a simplified form with arrows, as it results when the directional control valve 13 is switched accordingly and when the piston rod 16 extends.
  • a pressure medium, which is used to actuate the working cylinder 10 is introduced at the inlet connection 53 into the flange plate 12, where it reaches the inlet connection 52 in the flange surface 47.
  • the pressure medium now flows from the Pump pressure connection 52 to the first motor connection 46 in the flange surface 47, whereupon it flows through the flange plate 12 through the transverse channels 45 and the first transition opening 44 into the first pressure medium channel 36 in the first longitudinal strut 22. From there it passes through a first oblique bore 37 into the second pressure chamber 21 to the rear of the piston 15, so that the pressure building up there displaces the piston rod 16 outwards via the piston 15. At the same time 18 pressure medium must escape from the front pressure chamber. This is done in that the first pressure chamber 18 is connected via the second oblique bore 39 to the second pressure medium channel 38 in the second longitudinal strut 23.
  • pressure medium can reach the flange plate 12 via the second transfer opening 51 and flow to the second motor connection 48 via its transverse channels 49.
  • the outflowing pressure medium in the second motor connection 48 passes through the directional control valve 13 to the return connections 56, 57 and can then reach the outside via the outlet connection 58 and the exhaust air cap 59.
  • the 5/2-way valve 13 If the piston rod 16 on the working cylinder 10 is to be retracted, the 5/2-way valve 13 is switched over.
  • the directional control valve 13 then controls pressure medium from the pump pressure connection 52 to the second motor connection 48 and thus into the first, front pressure chamber 18, whereupon the piston 15, which is pressurized on the front, retracts the piston rod 16.
  • pressure medium from the second pressure chamber 21 is in turn controlled via the first motor connection 46 to the return connection 56 and can thus escape via the exhaust caps 59.
  • all pressurized channels are thus within a few components, including in particular the directional control valve 13, the flange plate 12 and the cylinder liner 11.
  • the risk of leakage pressure medium escaping is thus kept extremely low.
  • the flange plate 12 is guided in a perfect and captive manner on the cylinder liner 11 and can in their axial position can be adapted to the prevailing circumstances by merely drilling the two transition openings 44 and 51 on the two longitudinal struts 22 and 23 accordingly.
  • the cylinder liner 11 can be produced in a simple and cost-effective manner from a profile tube, the two pressure medium channels 36 and 38 being able to be installed in any way in two adjacent longitudinal struts 22 to 25.
  • the oblique bores 37 and 39 can be easily manufactured in the profile tube in terms of production technology.
  • the flange plate 12 with directional control valve 13 can be removed without having to remove the cylinder covers 17, 19 from the cylinder liner 11.
  • the working cylinder 10 is therefore versatile and can be manufactured inexpensively.
  • the longitudinal struts 22 to 25 as integrated components of the cylinder liner 11 perform a variety of functions; They not only serve to guide and hold the flange plate 12, but also form pressure-medium-carrying channels for controlling the working cylinder 10. Furthermore, if necessary, they can also be used for the function of tie rods if other types of cover are used instead of the cylinder cover shown.
  • the working cylinder is not limited to use as a pneumatic cylinder, but can also be operated with hydraulic pressure medium.
