Definitions

  • the invention relates to a machine tool, for example a lathe.
  • Such machine tools usually have a bed on which the individual machine modules, for example one or more tool carrier systems, one or more workpiece carrier systems, measuring units, loading and unloading devices, etc. are arranged.
  • the individual machine modules for example one or more tool carrier systems, one or more workpiece carrier systems, measuring units, loading and unloading devices, etc. are arranged.
  • the bed must be designed to be as stable as possible, since this is the only way to achieve high machining accuracy of the workpieces produced on the machine tool.
  • guideways are arranged on the bed, on which these machine modules run.
  • Different bed shapes are known, for example, lathe beds, sloping beds, vertical and overhanging beds, etc.
  • the beds are usually flat on the surface or on a base plate.
  • the different bed shapes serve on the one hand to achieve a good drainage of the chips produced during processing, and on the other hand to achieve the highest possible stability of the bed, especially from a dynamic point of view.
  • a problem is also the energy supply of the machine modules guided in the front area of such beds, which in turn have motors, for example for driven tools, movement of the tool carrier unit, eg. B. a tool turret etc.
  • the energy supply of the low-lying machine modules arranged below the machining position is particularly critical, since their energy supplies, which can be flexibly configured because of the longitudinal displacement, are in the area of the chip fall.
  • a headstock can also be guided along the portal bed, either on its front or on its underside, at this height, which means that tool unit guided on the underside is very good and low-pollution accessible for energy supply and without the machining position on the other side, e.g. B. the center of rotation of a lathe is too high for the operator standing in front of the machine, even if the processing position is in the lower height area of the bed, in particular in the lower half, because in the lower area, in particular guided on the underside lower tool support or the headstock is provided.
  • the portal bed has an approximately rectangular cross-section, at least at right angles to one another, carrying the individual guideways, outer sides, in particular underside and front side, makes the bed easy and inexpensive to machine.
  • guideways running exclusively in the Z direction and using identical guideways further cost reductions can be achieved on the one hand and on the other hand the individual machine models can be placed on different guideways.
  • all guideways in both transverse directions (X and Y direction) to the direction of displacement (Z direction) are designed to be form-fitting, in particular engaging behind.
  • the portal bed has through openings which are continuous in the longitudinal direction and are open on both sides and which can likewise be used to pass lines, in particular energy supply lines, from one end of the machine to the other.
  • the through openings generally consist of a plurality of, in particular, circularly arranged, circular through openings; when the portal bed is made from cast steel, the through openings generally remain between the surrounding, circumferential outer shell and the ribs formed integrally therewith so two or four large hollow chambers.
  • the height of the portal bed is 1, 0 to 1, 5 times as high as the depth of the portal bed, in particular square, and guides are preferably arranged only on the underside and front, namely on the underside a pair of guides and at least on the front a pair of guides.
  • No guideways are preferably arranged on the upper side in order to be able to accommodate energy supplies there.
  • a guideway could still be arranged on the front edge of the upper side, whereby, however, the upper front edge of the bed would only be slightly gripped by a machine module.
  • telescopic covers are preferably arranged in the longitudinal direction, which preferably always cover a pair of guideways together, for example the pair of guideways arranged on the underside.
  • the bed feet are preferably not part of the bed, but separate parts.
  • the portal bed is preferably on a base plate, which is designed as a welded construction, and the bed feet are preferably welded constructions, which are screwed onto the base plate or are integrally formed with it. It must be possible to move the bed relative to the load-bearing assembly, for example the base plate, due to thermal expansion of the bed in the machining operation, for example by corresponding play of the screw connections.
  • a base plate behind the bed of the machine tool are preferably also the required switch cabinets and energy supply devices such as hydraulic and pneumatic pumps and the like, and also a loading and unloading system for the machine is either attached to this base plate or directly on the front of the machine bed.
  • the control cabinets and energy supply devices can be placed as close as possible to the back of the bed or at such a large distance from it that a service aisle is created, from which maintenance and repair work is carried out from the rear of the machine Can observe the machine in operation.
  • the additional devices i.e. control cabinets and energy supply devices
  • the machine is transported in the fully assembled state, that is to say as a so-called hook machine, but preferably with the approximate position of the additional units on the bed, in that the bed with all the auxiliary units and machine modules located thereon, for. B. is lifted on the crane hook, and only after the installation, the additional units brought into the position spaced from the bed.
  • the chips are removed by means of a chip conveyor, which is arranged at a corresponding depth directly in front of the front of the machine bed.
  • a suitable sheet is attached between the uprights of the bed above the base edge.
  • a portal bed that is very uniform in terms of the stability of the bed due to its rectangular shape with identical, parallel Z-guides can be used for different machine structures:
  • a preferred embodiment is the design as a lathe, in which in particular the headstock and possibly the additional tailstock are guided on the underside of the portal bed, while machine modules, usually tool slide systems, are guided on the front and also on the underside.
  • a transverse arrangement for example in the vertical direction (X direction) can be selected, especially if the headstock is guided along the guideways on the top of the portal bed.
  • Forming as a milling machine with a tool holder in the upper area of the front of the portal bed is also possible, with milling units which are guided along the guideways of the upper side. If the unit carrying the workpiece is additionally longitudinally guided in the lower region of the portal bed, the longitudinal guides of the upper region of the front are additionally available for tool modules, measuring modules or the like. This also allows the machine to be shaped as a mixed milling / turning machine, i.e. both with tool modules that are pure milling modules, i.e. also with tool modules that correspond to those of a lathe, i.e. carry a tool turret with turning tools and, if necessary, additional driven tools.
  • Fig. 1 a lathe according to the invention in side view, with control cabinets arranged close to the bed of the machine, and
  • Fig. 2 another lathe in side view.
  • the portal bed 1 is raised against the ground, namely here the base plate 2, by means of two bed feet 3, which, viewed in the Z direction, are below the two longitudinal ends of the portal bed 1", and in the depth direction (Y Direction) of the bed preferably extend over the entire depth.
  • the portal bed 1 " is a stable beam with cavities, in particular through openings 6 'in the longitudinal direction, and in the solution according to FIGS. 1 and 2 consists of concrete or a plastic-concrete mixture.
  • guideways 5a to 5d are arranged, specifically a first pair (5a, 5b) on the underside, close to the front and at the rear edge of the underside 9, and two guide tracks 5c, 5d on the front side 8, the uppermost one being arranged near the upper edge and the lowest one near the lower edge.
  • the distance between the guideways of a pair is preferably the same.
  • the through openings 6 ' are of approximately square cross-section, and four through openings are arranged square to the center of the bed, so that the remaining material thicknesses at the top, at the bottom and between the through openings are approximately the same size, and also at the front 8 and rear 13.
  • the individual guideways 5 are each identical, and so are the guiding shoes 16 running on the guideways. While the guideways extend over substantially the entire length (Z direction) of the portal bed 1 ", 1 '", namely over the entire intended range of motion machine modules running on it, each machine module generally has in the longitudinal direction only at the beginning and at the end a guide shoe 16 which runs on the corresponding guide track 5.
  • the guideways 5 and the guide shoes 16 running thereon which are generally designed as roller guide shoes, are each formed in a form-locking manner in the other two spatial directions (X and Y direction), which offers the advantage that all longitudinal guides are of identical design , regardless of the direction in which gravity acts with respect to the guideway 5.
  • Known cable towing devices 17a, 17b are arranged on the rear side 13 and the top side 7 of the portal bed 1 ", 1" 'in order to track the energy lines to the machine products which are movable in the longitudinal direction.
  • U-shaped curved cable towing devices is - for. B. in the upper device 17b - one free end assigned to the portal bed 1 ", 1" 'near its rear edge, the other end, however, to the upper tool support.
  • a separate cable towing device is assigned to each individual tool unit.
  • the upper end is assigned to the lower tool unit at a height which is close to the underside of the portal bed 1 ", 1" ', so that the power lines to be passed on from this lower end of the cable towing device 17a then between the underside of the portal bed 1 ", 1 '" and the base, in this case the base plate 2, that is to say in the height region of the bed feet, can be guided to the bottom 9 and the lower longitudinally movable machine unit running there.
  • FIGS. 1 and 2 has the following equipment as machine modules:
  • An upper tool support consisting of an upper longitudinal slide 28a and an upper transverse slide 29a movable thereon in the X direction, runs on the two guide tracks 5c and 5d of the front 8, which in turn has one Tool turret 31 carries.
  • the headstock 24, in which the workpiece (not shown) can be rotatably held and driven with the aid of a chuck 27 on the center of rotation 20, can either be arranged fixedly on the portal bed 1 ", 1"'or can also be displaced along the guideways 5a, 5b be guided at the bottom.
  • a lower tool support, namely a longitudinal slide 28b, is also guided on the two lower guide tracks 5a, 5b of the underside 9 of the portal bed 1 ", 1 '", on the transverse guides of which a cross slide 29b can be moved in the Y direction, which carries a tool turret 31 whose tools can work on the workpiece.
