Definitions

  • Machine in particular machine tool
  • the invention relates to a machine, in particular a machine tool, such as a milling machine, with a machine frame and arranged thereon machine modules.
  • Machines in particular machine tools, are available in a wide variety of designs. These include, for example, drills, lathes, grinding machines or milling machines, but also other machines that are used primarily for the machining of workpieces. Common to all these machines is that they must have a certain stability in order to be able to machine a corresponding workpiece as precisely as possible. Therefore, they usually have machine frames and other machine modules, which can be designed differently depending on the type of machine tool, made of metal, especially steel on. Metal has the advantage that it is relatively easy to work and to obtain in various strengths. However, the disadvantage of using metals is above all their relatively high price of raw materials.
  • the machine frame which practically functions as the main body of the machine, and / or at least one of the machine modules is made at least partially of high-strength or ultra-high-strength concrete.
  • the use of this material results in a number of advantages.
  • the machine for example a tool
  • the temperature sensitivity is low.
  • the use of formwork, advantageously made of wood virtually unlimited possibilities in the shape of the machine frame and / or the machine modules, which are in no way inferior to the possibilities in the shaping of metal.
  • even complex components can be created that could previously be cast only from metal, welded or forged.
  • high-strength concrete also has the advantage that it has a lower shrinkage tendency compared to cast steel. Also, a possible shrinkage can be almost completely anticipated by a corresponding heat treatment. Last but not least, the significantly lower price in relation to metals should be emphasized. In addition, it should be emphasized in this context that the invention is not limited to machines in the form of machine tools. Rather, all machines can be formed according to the teachings of the invention, which must have a particularly high strength.
  • the machine advantageously has at least one machine module in the form of a frame element, a machine table, a tool holder, a pivoting and / or rotating device and / or a guide device.
  • the machine table primarily serves to support a workpiece to be machined
  • the pivoting and / or rotating device can perform a wide variety of tasks.
  • such devices can be used, for example, when turning or pivoting a workpiece but also other components, such as the tool holder itself.
  • Guiding devices are always used when a machine module is to be mounted movably relative to a further machine module, the machine frame and / or the workpiece to be machined.
  • all components of the machine can be made of high-strength concrete, which must have a corresponding strength.
  • Conceivable is the use of high-strength concrete for the production of quills, as another linear axis and the transmission of torque to the tool and / or the workpiece are used.
  • machine modules also includes a variety of struts, bearing elements or stiffening elements, which may be present depending on the machine.
  • At least one machine module is at least partially bonded to the machine frame and / or another machine module.
  • conventional fasteners such as screws or bolts.
  • conventional fasteners can also be combined with the bonding techniques known in the art.
  • a wide variety of mechanisms known to those skilled in the art can be used which advantageously ensure a connection which can be released again at any time.
  • the machine has at least one guide element on which the machine frame is movably mounted.
  • the use of one or more guide elements is for example advantageous if the workpiece is stored stationary and the machine, in particular in the form of a machine tool, such as a milling machine or a traveling column machine, must be moved relative to this for machining the workpiece.
  • a machine tool such as a milling machine or a traveling column machine
  • the machine has elements such as sliding ments, for example runners, or else rollers, which interact with the guide elements.
  • a drive advantageously with an associated control unit, can be provided which moves the machine along the guide element.
  • the guide element comprises at least one base plate and / or a guide rail, which in turn can rest on the base plate.
  • the guide element is mounted in a particularly advantageous manner on a foundation. This ensures that the machine has a stable bearing so that the workpieces to be machined can be machined with the highest possible accuracy.
  • the foundation and / or the guide element also has anchors for connecting the foundation and guide element and / or for fine adjustment of the position of the guide element and / or foundation.
  • the anchoring is designed such that the said fine adjustment, for example by means of corresponding screw mechanisms, is made possible, the height and / or the position of the guide element in particular with respect to the foundation can be adjusted exactly. This results not least in a particularly high working accuracy of the machine.
  • Such anchors can be formed for example by bolts, but also by screw or threaded rods, the same ensure a stable connection of foundation and guide element (s).
  • the anchors can be fixed but also releasably connected to the foundation and / or the guide element, whereby corresponding wedge elements can be used, which represent an additional assurance of the compound.
  • the anchors are glued to the foundation and / or the guide element and / or encapsulated with, in particular cement mortar.
  • Such a connection provides a stable yet easy to implement fixation of the anchorage.
  • the guide element can be glued or cast directly without the use of appropriate anchors directly to the foundation, whereby a particularly simple design can be realized.
  • the guide element and / or the foundation is made of high-strength concrete, since these components are usually exposed to high loads, especially in the form of high pressure loads.
  • the said components can be produced with very high accuracy, which is particularly in the design of the guide elements of considerable advantage, since their accuracy has a direct effect on the machining accuracy of the corresponding workpiece.
  • the machine frame has an E-modulus with an amount of greater than 50,000, in particular greater than 60,000 N / mm 2 , on. This ensures that the concrete can withstand the highest loads and has as little deformation as possible. This is particularly advantageous when the machine has to transfer large forces to a workpiece to be machined, while still ensuring a high machining precision.
  • the high strength of the concrete is mandatory if the machine has a certain size, resulting in correspondingly high forces acting on the machine itself.
  • corresponding milling machines are used, for example, in the processing of Transrapid carriers, which generally have a height of more than 1 m.
  • the high-strength concrete is high-strength lightweight concrete.
  • the weight of a machine produced from it can be significantly reduced while still providing sufficient stability. This is especially for moving tool modules, such as the tool holder or corresponding pivoting or rotating devices of decisive advantage.
  • the concrete is low shrinkage. This ensures that the machine components made therefrom remain dimensionally stable even after their completion. In addition, the time between the casting of the component and the subsequent processing is shortened.
  • the concrete is additionally or alternatively heat treated. This process results in particular in a significant acceleration of the curing process of the concrete.
  • the concrete contains additives.
  • additives such as superplasticizers, silica or other the Known specialist, contribute to the fact that the nature of the concrete can be influenced depending on the nature of the additive.
  • the admixture of fibers has proven itself, since their use has a particularly positive influence on the stability of the concrete.
  • the prestressing of the concrete is particularly useful with flexurally stressed components and can be carried out either in direct bonding or by external prestressing.
  • Figure 1 is a schematic side view of an inventive
  • Machine in the form of a machine tool
  • Figure 2 is a schematic front view of an inventive
  • Machine in the form of a machine tool.
  • Figures 1 and 2 show a schematic side and a corresponding front view of a machine according to the invention.
  • a machine tool has been selected in the form of a milling machine 1, whereby, of course, other machines, such as, for example, rotary or drilling machines, but also grinding machines, can be designed according to the teaching of the patent claims.
  • the term machine in the context of the invention also includes a variety of other machines that are used in particular for processing a workpiece, or that must be made for other reasons from a high-strength material.
  • the milling machine 1 in this case has a machine frame 2, which practically serves as a base body for receiving further machine modules, as described below.
  • the machine frame 2 has a frame element 3, in which a tool holder 4 by means of guide rungsvorraumen 5 is mounted vertically movable.
  • the tool holder 4 has a pivoting or rotating device 6, which is rotatably mounted about a horizontal axis 7 (see FIG. 1) but also about its longitudinal axis extending in the plane of the drawing of FIG.
  • the tool holder 4 is mounted such that it is also horizontally displaceable along the longitudinal axis.
  • a tool not shown, for example, a milling head, be oriented in all three spatial axes corresponding to the desired shape of a tool to be machined.
  • the vertical movement of the tool holder 4 within the guide devices 5 can be effected by means of spindle or chain drive, which are assigned correspondingly controllable drive units 8.
  • the tool holder 4 itself has a drive, not shown, which serves for the actual rotational movement of the tool.
  • the machine frame 2 is movably connected to a guide element 9 (for the sake of clarity only provided with reference numerals in FIG. 1).
  • a guide element 9 (for the sake of clarity only provided with reference numerals in FIG. 1).
  • This consists in the embodiment shown of a base plate 10, which has two parallel guide rails 1 1. These are in turn encompassed by corresponding runners 12 of the base frame, in order to ensure a secure guidance of the same along the guide element 9.
  • runners 12 instead of runners 12, of course, rollers or other sliding elements can be used.
  • this also has a foundation 13 which is connected to the guide member 9.
  • the connection between the base plate 10 of the guide member 9 and the foundation 13 can be done using various adhesive techniques, but also in a conventional manner by means of screw or plug connections.
  • the connection is realized by means of anchors in the form of bolts and / or threaded rods 14, the corresponding holes in the foundation 13 and the Base plate 10 are added.
  • the threaded rods 14 themselves are in turn glued into the holes or are received by correspondingly existing threaded elements, whereby a particularly simple yet stable connection between the base plate 10 and the foundation 13 is formed.
  • the guide rails 11 is connected directly to the foundation 13 in one of the above ways.
  • the machine frame 2 and / or individual machine modules such as the frame element 3, the guide device 5, the base plate 10 of the guide element 9, the guide element 9 itself, the tool holder 4 and / or the foundation 13 are at least partially made of a high-strength concrete, whose modulus of elasticity in an advantageous embodiment has an amount of more than 50,000 N / mm 2 and, in a particularly advantageous embodiment of the invention, an amount of more than 60,000 N / mm 2 .
  • high-strength lightweight concrete can be used, whereby the weight of the machine tool can be significantly reduced. Since most machine tools are to machine corresponding workpieces while maintaining particularly high accuracies, it also makes sense to use low-shrinkage concrete in order to ensure adequate dimensional stability of the corresponding components.
  • the additives mentioned are usually added to the still liquid concrete. Finally, this is poured into an appropriate formwork. sen and after curing by machining, for example, by grinding or milling, brought into the final shape of the desired component, which accuracy of a few microns can be achieved by today's formwork and processing methods.
  • drilling devices may also be used, for example for producing corresponding receptacles for the threaded rods.
