Mit den bekannten teleskopartig zusammenschiebbaren Abdeckungen für Werkzeugmaschinen ist eine staub- und wasserdichte Abdeckung nur zu erreichen, wenn die einzelnen Teile der Abdeckung sehr genau ineinanderpassen und sämtliche Teile mit großer Genauigkeit gegeneitnandergeführt sind. Eine solche Abdeckung ist aber nur unter Aufwand hoher Kosten herstellbar, und das Arbeiten einer solchen Abdeckung ist nur dann gewährleistet, wenn die aufeinander gleitenden Flächen glatt und sauber bleiben. Das ist aber praktisch nicht erreichbar.With the known telescopically collapsible covers for machine tools is one Dust and waterproof cover can only be achieved if the individual parts of the cover are very precise fit into one another and all parts are guided towards one another with great accuracy. Such a cover but can only be produced with high costs, and the work of such a cover is only guaranteed if the surfaces that slide on each other remain smooth and clean. That is but practically unreachable.

Um die teleskopartigen Abdeckungen billig und betriebssicher herstellen zu können, ist erfindungsgemäß die teleskopartige Abdeckung mit einer bekannten faltbaren Abdeckung so kombiniert, daß die faltbare *5 Abdeckung die Abdichtung der Führungsbahn der Werkzeugmaschine gegen Staub und Flüssigkeit übernimmt, während der zusammenschiebbare tragfähige Teil der Abdeckung die mechanischen Kräfte und die Späne aufnimmt. Hiermit ist der entscheidende Vor- ao teil erreicht, daß die einzelnen Teile der teleskopartigen Abdeckung nicht mehr genau ineinanderpassen müssen, sie können Spiel gegeneinander haben, da etwa durchdringender Staub oder durchlaufende Flüssigkeit von der faltbaren Abdeckung aufgenommen «5 werden.In order to be able to manufacture the telescopic covers cheaply and reliably, according to the invention the telescopic cover is combined with a known foldable cover in such a way that the foldable * 5 cover seals the guideway of the machine tool against dust and liquid, while the collapsible load-bearing part of the cover takes over the absorbs mechanical forces and the chips. Herewith the key advantages is ao partially achieved, the individual parts of the telescopic cover that do not need to fit into each other exactly, they may have toward one another game since about penetrating dust or liquid passing through the foldable cover included '5 are.

Um die genaue Führung der einzelnen teleskopartigen Glieder gegeneinander entbehrlich zu machen, werden diese so ausgebildet, daß jedes Glied mit dem AOrhergehenden und ihm folgenden in der ausgezogenen Stellung und in der zusammengeschobenen Stellung der Abdeckung verriegelt ist und daß die Verriegelung erst gelöst wird, wenn das vorhergehende Glied in das folgende eingeschoben bzw. das vorhergehende vom folgenden vollständig bzw. nahezu vollständig abgezogen ist. Damit ist erreicht, daß jeweils nur zwei Teile der Abdeckung eine Verschiebung gegeneinander ausführen und daß sich diese beiden Teile gegeneinander ausrichten können. Es ist dann nicht mehr erforderlich, die einzelnen Teile der Abdeckung durch die an sich bekannten Scheren od. dgl. gegeneinander zu führen.In order to make the precise guidance of the individual telescopic members against each other superfluous, these are formed in such a way that each limb is drawn out with that which precedes and follows it Position and in the collapsed position of the cover is locked and that the lock is only released when the previous link is inserted into the next or the previous one is completely or almost completely deducted from the following. This achieves that in each case only two parts of the cover move against each other and that these two parts align against each other. It is then no longer necessary to remove the individual parts of the cover by the known scissors or the like. To lead against each other.

Die Abdeckung wird weiter vorteilhaft so ausgebildet, daß das üblicherweise mit dem Schlitten der Werkzeugmaschine verbundene Abdeckungsglied das folgende beim Zusammenschieben so weit anhebt, daß dieses und damit auch beim weiteren Zusammenschieben die nachfolgenden von dem ersten Abdeckungsglied getragen werden. Damit wird ein Verschieben der Stützflächen der Abdeckungsglieder auf der Führungsbahn vermieden.The cover is also advantageously designed so that this is usually done with the carriage of the Machine tool connected cover member raises the following when pushed together so far that this, and thus also the subsequent ones when they are pushed together, are carried by the first cover member. This creates a shift the support surfaces of the cover members avoided on the guideway.

In Abb. 1 ist die Führungsbahn der Werkzeugmaschine, beispielsweise eines Bohrwerkes, mit 1 bezeichnet, der Schlitten mit 2 und einer der Ständer der Maschine mit 3. Die Abdeckung besteht aus den Elementen 4 bis 8. Am Schlitten 2 ist das Z-förmig gebogene Blech 4 befestigt, sein Teil 9 dient zur Befestigung am Schlitten 2, sein Teil 11 zur Abdeckung, und sein Schenkel 10 endet über der Führungsbahn 1. Das nächste Element 5 liegt in ausgezogenem Zustand mit dem freien Ende 12 auf dem Schenkel 10 des Elementes 4 auf und stützt sich am anderen Ende mit seinem Schenkel 13 auf der Führungsbahn 1 ab. Im zusammengeschobenen Zustand, den Abb. 1 darstellt, wird das Element 5 und die folgenden vom Element 4 getragen, und zwar wird es am Ende der Einschiebbewegung von den Rollen 14 angehoben, die an den Ecken jedes Elementes befestigt sind. Diese Rollen vermindern gleichzeitig die Reibung zwischen den Elementen.In Fig. 1, the guideway of the machine tool, for example a boring mill, is denoted by 1, the carriage with 2 and one of the stands of the machine with 3. The cover consists of the Elements 4 to 8. The Z-shaped bent sheet metal 4 is attached to the slide 2, its part 9 is used for attachment on the slide 2, its part 11 for covering, and its leg 10 ends above the guide track 1. The next element 5 is in the extended state with the free end 12 on the leg 10 of the Element 4 and is supported at the other end with its leg 13 on the guide track 1. in the In the collapsed state shown in Fig. 1, element 5 and the following from element 4 carried, and that it is raised at the end of the insertion movement of the rollers 14, which are attached to the Corners of each element are attached. These roles also reduce the friction between the Elements.

Die einzelnen Elemente 4 bis 8 sind an den zur Führungsbahn parallelen Seiten durch Bleche 15 geschlossen, die nach unten über die Führungsbahn 1 hinweggreifen. Jedes Element bildet also einen nach zwei Seiten hin offenen Kasten, wobei die einzelnen Kästen sich teleskopartig ineinanderschieben lassen. An den Schenkeln 10 und 13 der einzelnen ElementeThe individual elements 4 to 8 are closed on the sides parallel to the guideway by metal sheets 15, which reach down over the guideway 1. So each element reproduces one Box open on two sides, whereby the individual boxes can be telescoped into one another. On the legs 10 and 13 of the individual elements

Claims

the concertina-like foldable parts 16 are attached, which takes over the sealing of the guideway against dust and moisture. The individual elements are in the extended position. Position locked against each other, as shown in Fig. 3 and 4. It is not possible to push the elements together without releasing the lock. The release of the lock only happens for each element when the previous one is almost completely inserted into the next, that is, it is carried by it. The lock itself consists, as Figs. 3 and 4 show, of rails 17 and 18, which, as the "left half of Fig. 4 shows, are guided in sheet metal brackets 19 on the legs 13, through cutouts in the side walls 15 reach through and lock two elements together. The rails are under the action of springs (not shown). A wedge-shaped part 20 fastened to the legs 10 or 13 of each element, which is shown in cutouts 21 and 22 of the rails 17 and 18 can be pushed in and thereby displaced them in opposite directions to one another. This displacement releases the locking of the wall parts 15. This locking prevents the elements that are not supposed to move from being pushed together right part still has a second lock that comes into action when the cover is pulled out and ensures that only the element is released, which is its en has reached the valid position in relation to the guideway. On the legs 13 of each element, with the exception of the first element 4, a lever 24 is mounted at 23, which is loaded with a spring 25 and engages through a cutout 26 of the leg 13. A cutout 27 is made in the leg 10 of the first or leg 13 of the respective preceding element. When pushed together, the nose 28 of the lever 24 is pushed through the opening 27 and thereby engages behind the wall 10, so that when the part 4 moves back, the element 5 is carried along by the lever 24. If the end 29 of the lever 24 strikes the end of a cutout 30 in the wall 15, the lever is rotated against the spring 25, i. That is, the element 5 is released so that the element 4 can move on independently of the element 5. Fig. 5 shows another way of building the cover. The parts 16, which can be folded like a concertina, are connected to frames 38 and these are connected to frames that support elements 4 to 8. The operation of the device is as follows: In the extended position of the cover, the horizontal leg of each element that forms the cover is supported once on its vertical leg, based on the guide track, on this and on the other on the vertical leg of the adjacent element. Since the cantilevered length of the horizontal leg is relatively small, considerable forces can be absorbed even with relatively small sheet metal thicknesses. It is therefore possible without difficulty to create a cover that can be walked on with sheet metal thicknesses of around 4 mm. In the extended position, as described, the individual elements are locked to one another in pairs by the rails 17, 18, with the exception of the first element 4 fastened to the slide, the limb 10 of which is only used to fasten the bellows part 16. The lower sides of the legs of the elements forming the cover are designed with a slight inclination, so that when each element is pushed into the adjacent one, this element is slightly raised shortly before the lock is released, ie. H. is carried by the element attached to the carriage. So there is no displacement of the vertical legs of the elements on the guide track and thus wear on the track. Patent claims:
