Abstract
At least one machine tool, preferably two machine tools (1, 2) is or are provided for the production of workpieces, or for the complete production of complex workparts, which machine tools each have a basic body (3, 4) and machine units (7, 8) movable in the horizontal direction thereon. Each machine unit has a work spindle (13, 14) which is supported displaceably in the axial direction of the spindle in a carrier (11, 12) of crankshaft-like design. The carrier is mounted pivotably and supports each work spindle above a respective transport system (31, 32) for a workpiece or the workparts (37, 38). Machining devices, for example in the form of a tool carrier (44) for turning, drilling and/or milling tools, a laser-welding device (46), a grinding device (47) and a brushing device (48), and also an apparatus for joining, are provided in the functional area of one of these machine tools.
Description
- The invention relates to a method and an apparatus for the production of workpieces, in particular for the complete production of complex workparts.
- For the manufacture of workpieces, in particular workpieces with different successive machining steps, it has hitherto been necessary to rechuck the workpieces for the individual machining steps or, if appropriate, to transfer them to another machine tool, which increases the amount of work involved and is detrimental to precision.
- For the manufacture of complex workparts, in other words assemblies made up of several parts, it is known to form the blanks of these workparts from a starting material by primary forming or reforming, so as then, via the procedural steps of separating, joining, coating and the operation for changing material properties, to bring about the final state and the material properties necessary for this. In this connection, special equipment in the form of machine tools is used for each of these procedural steps. The interlinking of the work operations on the individual machines is in this connection performed manually or automatically. In the case of manual linking, the amount of work involved is considerable, and, in the case of automatic linking, production lines with a considerable space requirement are frequency necessary.
- It is an object of the invention to simplify production of workpieces and complete production of complex workparts with regard to both the amount of work involved and the space requirement of the machines to be used.
- According to the invention, this object is achieved in a method for the production of workpieces by virtue of the fact that different machining devices can be used in the functional area of at least one multifunctional machine tool and the workpieces to be produced are brought into the most favorable position for machining by means of a machine unit with a work spindle of the machine tool, which spindle is pivotable and works according to the pick-up principle.
- With regard to a method for the complete production of complex workparts, the object is achieved according to the invention by virtue of the fact that different machining devices can be used in the functional area of at least one multifunctional machine tool and the workparts to be produced, consisting of at least two workpieces, are brought into the most favorable position for the machining concerned by means of a machine unit with a work spindle of the machine tool, which spindle is pivotable and works according to the pick-up principle.
- In this connection, a multifunctional machine tool is a machine in which, on account of the characteristics described, namely the possibility of working according to the pick-up principle and the pivotable arrangement of the work spindle, a workpiece, or an already assembled workpart, can be subjected to the most varied machining operations in very different positions. By virtue of the use of such a multifunctional machine tool, it is possible to bring the part to be machined into the most favorable position for the machining concerned. This is especiaiiy advantageous for the reason that, in this way, the machining devices can be designed simply and can also be used in a simple manner in the functional area of this machine tool, which encompasses both the stationary arrangement of such machining devices in the functional area of the machine tool and the movable use of such machining devices. It is likewise possible to design the work sequence more favorably.
- According to the invention, an apparatus for the production of workpieces, in particular those in which several consecutive work steps are necessary, or for the complete production of complex workparts, which apparatus can serve in particular for implementing the methods explained above, is characterized in that it has at least one multifunctional machine tool with a machine unit comprising a work spindle which is supported displaceably in the axial direction of the spindle, in a pivotably mounted carrier, for implementing the pick-up principle, in that the machine unit is arranged above a transport system for the workparts or workpieces and machining devices for the workpieces, and in that the machining devices are designed so as to be usable in the functional area of the work spindle.
- In this connection, the work devices can be arranged in a stationary manner in the functional area of the machine tool or, according to another embodiment, the machining devices can be designed so as to be movable into the functional area of the machine tool.
- According to a further embodiment of the invention, each machine unit can be moved in the horizontal direction transversely to the pivoting axis of the carrier for the work spindle. This embodiment widens considerably the applicability of the machine tool, the effect of this advantage being greater still in the variant with the machining devices which can be moved into the functional area of the machine tool.
- A space-saving embodiment of the machine tool is achieved by virtue of the fact that the work spindle is designed as a motor spindle.
- A further embodiment of the invention, which consists in that the pivotably mounted carrier for the work spindle is of crankshaft-like design, is especially advantageous. This embodiment is particularly advantageous if the crank part is, in the vertical position of the work spindle, located above the bearing part of the carrier, because an especially high working area is then available under the work spindle.
- An embodiment of the apparatus according to the invention which can find widespread application consists in that one machining device is designed as a tool carrier for receiving turning, drilling and/or milling tools. In this way, the most varied types of chip-removing machining of a workpiece or of an already assembled workpart can be carried out.
- One machining device can furthermore be a grinding device.
- An advantageous embodiment consists in that one machining device is a holding and positioning device for one of the parts to be joined together of a complex part to be manufactured and the work spindle, holding another part, serves for carrying out a joining operation or pressing operation. In this way, at least two parts of a complex workpart can be joined together within the functional area of the machine tool.
- In order for it to be possible in addition, after a joining operation, for the individual parts of a complex part to be interconnected rigidly or for one of the parts to be hardened, it is advantageous if one machining device comprises a laser-welding device or laser-hardening device, as the connection operations and hardening operations can be carried out within the functional area of the machine tool, for which purpose it was hitherto necessary to produce the individual parts on very different machine tools.
- It is also in accordance with the concentration of the various machining operations in the functional area of the machine tool if one machining device is a brushing device, so that the tools can be cleaned, for example after welding or hardening.
- If the work spindle is also involved in a pressing operation in addition to a joining operation, it is advantageous, on account of the great forces arising in the process, which act on the bearing arrangement of the work spindle, if the work spindle can be clamped firmly in its carrier. In this way, it is possible to keep the great forces arising during the pressing operation away from the bearings of the work spindle. During the pressing operation, it is then necessary to provide the transport system with special devices, in order that the counterpressure can be taken up.
- The machining possibilities in both the production of workpieces and the complete production of complex workparts can be increased by virtue of the arrangement of two machine tools. In the event of the arrangement of two machine tools, it can be advantageous if the basic bodies for receiving the movable machine units are arranged so as to be separate from one another with regard to the transmission of vibrations.
