Definitions
- Component such as manifold connection plate, intermediate plate valve.
- the invention relates to a component such as a manifold connection plate, an intermediate plate valve, a control housing and the like for the vertical and / or horizontal, modular construction of hydraulic or pneumatic control units, which component has a matching connection hole pattern of the main channels for the supply or discharge of the pressure medium in the mutually opposite connecting surfaces of the component and which component has passages provided in areas of the component for the shaft of fastening screws for Hole pattern of the main channels overlapping connecting adjacent components with each other.
- Components of this type are used for the compact construction of technical systems for absorbing and transmitting mechanical stresses and energies using technical fluids, in particular for the compact construction of hydraulic or pneumatic control units.
- these components offer, due to their modular design, a considerable space saving in the construction of such systems or control units and, moreover, high operational reliability.
- connection of the components intended for the respective application is accomplished with the aid of appropriately long fastening screws, so-called tie rods, and fastening nuts.
- this connection solution has the disadvantage that defined connection forces between the components cannot be achieved with regard to the more or less long tie rods provided for the respective application, because of their behavior which varies according to their length with regard to longitudinal expansion and the generation of torsional forces. Precisely because of the tightening of the tie rods or. Tightening nuts arising in the tie rods can lead to leaky connections between the components.
- the aim of the present invention is. to improve a component of the type mentioned to the extent that the construction of control units from such components can be carried out simply and quickly with an overall secure connection of the components to one another.
- the aim is to make the component structurally simple in the sense that it can be manufactured at the lowest possible cost.
- the component proposed according to the invention enables simple and easy construction of a pneumatic or hydraulic control unit or of such a technical system.
- the fastening screws provided for the connection of adjacent components from a direction parallel to the direction of assembly of the control unit - that is to say transversely to relevant connection surface of a component and axially to the respective fastening screw - and are therefore easily accessible.
- these expediently have a conventional internal hexagon, but of course other shapes of the end of the head of the fastening screw facing away from the threaded shaft are also possible for the engagement of corresponding tools, in particular thus a socket wrench.
- a relatively simple tool can be used to connect such components with a predeterminable tightening force of the fastening screws and in any case without the occurrence of significant torsional forces in the fastening screws.
- the bores provided in the component for forming a cage for the head of the fastening screw in question as a slavehole and to expose them in the open - that is, the bet the connecting surface facing the building element - to be closed at the end by means of a threaded sleeve, as stated in claim 3.
- the execution r form according to claim 2 can also be designed according to the proposal according to claim 4.
- this side of the passage can have the end of a stepped bore in question, which has a reduced diameter, or else a threaded sleeve carrying an external thread can be formed, which is screwed into the component in this area.
- the latter preferably carries an external thread, for. B. a left-hand thread, which runs opposite to the thread of the fastening screw, in the example a right-hand thread. This ensures that the threaded sleeve cannot loosen as a result of torques acting on the threaded sleeve when the fastening screw is tightened, but rather under the effect of such torques. pulled even tighter against the existing stop.
- Fig. 1 as components of the invention two interconnected manifold plates in the
- FIG. 2 the interlinking plates according to Fig. 1 in plan view.
- the drawing shows two external cuboidal connecting plates 1 and 2 which are detachably connected to one another by means of three fastening screws 3, 4 and 5.
- the connecting surfaces denoted by 6 and 7 lie respectively
- Interlinking connection plates 1 and 2 with a pressure corresponding to the tightening torque of the fastening screws and the main channels P and T ending in the respective connection surface 6 or 7 for the so-called pressure or tank connection are connected to one another - with an overlapping, mirror-image identical connection hole pattern .
- Seals in the form of O-rings, not shown, are provided in a manner known per se for establishing an airtight or liquid-tight connection between the relevant adjacent main channels and possibly further channels, not shown.
- sectional illustration according to partial section AA shows one of several possible embodiments for the arrangement and design of a bore forming the cage for the head of the fastening screw in question, while the sectional darelking according to partial section BB shows another possible solution for this hole.
- a bore 8 is provided in the interlinking connecting plate 1 or 2 for each fastening screw 3 from the lower side of the interlinking connecting plate, based on the illustration in FIG. 1 of the drawing, and in fact axially extending with the 9 designated passage for the threaded shaft 10 of the relevant fastening screw 3.
- the diameter of the bore 8 is slightly larger than the outer diameter of the head of the fastening screw 3 designated 11, and the passage 9 has the thread of the threaded shaft 10 of the Fixing screw 3 corresponding thread.
- a shoulder 12 At the transition point between the bore 8 and the passage 9 - which together form a stepped bore - there is a shoulder 12.
- a threaded sleeve 14 At the end of the bore 8 opposite the shoulder 12 there is a threaded sleeve 14 provided with a passage 13 for the threaded shaft 10 of a fastening screw 3 which is screwed by means of an external thread into the bore 8 which has a corresponding internal thread at the free end.
- These threads preferably run counter to the course of the threads of the threaded shaft 10 of the fastening screw 3 or that of the passage 9. This prevents any possible loosening of the threaded sleeve 14 due to the action of torques when tightening a fastening screw.
- Head 11 of the fastening screw 3 form a corresponding mobility for the fastening screw 3 with an axial clearance d m.
- the fastening screw 3, for example - and preferably - provided with an internal hexagon in the head 11 of a manifold connection plate 1 or 2 can thus pass through the passage 13 of the manifold connection plate 1 or 2 assigned to this fastening screw 3 by means of a corresponding tool Thread of the passage 9 of the subsequent manifold connection plate 1 or 2 are screwed.
- the entire length of the threaded shaft 10 of the fastening screw 3 can be kept relatively short and the access to the head 11 for the purpose of screwing two interlinking connection plates to one another and releasing them from one another is simple and uncomplicated with the possibility of predetermined contact pressures of the respective connecting surfaces of the two interlinking connection plates to be achieved by applying certain tightening torques for the fastening screws.
- a stepped bore is also provided in the interlinking connection plate 1 or 2, but with the difference from the solution according to partial section AA that the head 16 of the fastening screw 4 corresponding to the fastening screw 3 accommodating the bore designated 17 is introduced from the other side - the other connecting surface - into the interlinking connection plate 1 or 2 and accordingly the free end of the bore 17 facing the head 16 of the fastening screw 4 is closed off by means of a threaded sleeve 18.
- interlinking connection plate shown and described in the exemplary embodiment explained above
- the invention can of course also be used with advantage in other components provided for the modular construction of hydraulic or pneumatic control units. e.g. in so-called intermediate plate valves or control housings.
