Definitions

  • the invention relates to a machine tool with a workpiece carrier and a plurality of processing units arranged around the workpiece carrier, which can be controlled by a central control unit.
  • a plurality of workpiece carriers are arranged on a table which can be incrementally advanced, around which a plurality of processing units are provided, each of which processes a different workpiece.
  • the workpiece is machined from the same side after the table has been indexed by the next machining unit. If the workpiece is to be machined from another side, it is necessary to reclamp this workpiece on the workpiece carrier. This requires a greater outlay on workpiece carriers and a greater outlay on set-up times. There is also the risk of dimensional deviations during reclamping if this source of error is not eliminated by increased effort, ie by additional devices. These additional devices are described in the aforementioned DE-AS 16 02965.
  • the object of the invention is to design a machine tool of the type described at the outset such that, with a reduced outlay on the machine tool in conjunction with a space saving, a considerable saving of time is possible in the machining of a workpiece, a unive rs elle Possible application with a quick transition to another machining program should be possible.
  • the workpiece holder for the central holding tion is formed in relation to the machining units of at least one workpiece, that the machining units can be controlled simultaneously in at least three axes and that the control unit is trained for the simultaneous control and monitoring of all axes of all machining units.
  • This configuration of the machine tool creates a machining center in which all machining units are controlled and monitored via a centralized control unit, as a result of which a workpiece can be machined simultaneously from at least three sides without the workpiece having to be machined from one Continuing processing unit to another.
  • several workpiece carriers and several control units are saved, since not each workpiece is processed simultaneously by one processing unit, but by several processing units, which are controlled and monitored by a central control unit not only to carry out the necessary machining, but also to avoid a collision of the tools working at the same time.
  • the machine tool according to the invention can be used with a single switchable table, a tool changing system, a workpiece holder changing system, a tool magazine, a single swiveling device for swiveling the workpiece holders, a central cooling system and a central lubrication system get along, on top of which only a single operator is required. Further advantageous embodiments of the invention result from the subclaims.
  • Fig. 1 is a top view of a machine tool according to the invention
  • Fig. 2 is a view in the direction of arrow II in FIG. 1;
  • Fig. 3 is a view in the direction of arrow III in FIG. 1 .
  • four consoles 2, 3, 4 and 5, arranged in a cross-shaped manner with respect to one another, are arranged around a table 1, which can be incrementally or continuously advanced, on which three processing units 6, 7 and 8 are arranged, these processing units on consoles 3 to 5 are provided.
  • the console 2 carries a workpiece carrier changing unit for the optionally automatic changing of two workpiece carriers 10, one of which is arranged on a workpiece carrier changing unit 9 with full and one with dash-dotted lines.
  • the workpiece changing unit 9 is pivotally mounted, namely in accordance with the double arrows 11 and 12.
  • Each workpiece carrier is designed as a pallet and can be moved in the direction of the double arrow 13 by the workpiece carrier changing unit 9 on the table 1.
  • the processing unit 6 is designed as a turret head unit with a plurality of drill heads, while the processing units 7 and 8 are designed as numerically controlled horizontal-vertical processing units with a swivel head, as are already known for individual use.
  • 19 denotes a cable towing device, which is assigned to the processing unit 7 and 8 and through which the necessary cables and hoses are carried when the processing units are moved.
  • a tool magazine 14 is provided on supports 16, which is designed as a revolving chain 15, which is guided in a rail 18. Certain links in the chain have a holder 20 for a workpiece 21 as an integrated component.
  • a tool changing device 17 is held on a support cross 22 centrally above the table 1, with the support cross 22 on the supports 16 is supported.
  • the tool changer has a two-armed changer 23 which is pivotally mounted about an axis 24 which is at an angle of 45 ° to the horizontal.
  • the two arms 25 and 26 of the changer 23 serve on the one hand to remove a tool from the magazine 14 and to replace it with a tool of the processing unit, this tool being gripped by the other arm and being guided into the tool magazine.
  • the running rail 18 for the chain 15 is guided in such a way that the tool changer 23 can remove any desired tool from the tool magazine 14 and exchange it for a tool that is just clamped in the processing unit.

  • a control unit 27 which can be programmed by an input device, is set up in a cabinet arranged directly next to the machine tool.
  • All axes of the processing units 6 to 8 can be controlled and checked by the control unit.
  • this central control unit also takes over the automatic tool and workpiece change.
  • the workpiece change takes place by moving the workpiece carrier 10 from the table 1 to the workpiece changing unit 9, for which the workpiece carriers are designed as pallets on which the workpiece can be clamped by means of slot nuts which can be inserted into grooves in the workpiece carrier.
  • the tool carrier coming from the table is exchanged for a tool carrier that has already been prepared by both workpiece carriers can be pivoted in the direction of arrows 12 and 13 by means of the workpiece holder changing unit 9, so that the prepared new workpiece holder can be moved onto the table 1.
  • the workpiece carriers are held on the table 1 by hydraulic, electrical-mechanical or pneumatic eu matic clamping devices (not shown) as soon as they have reached their operating position.
  • the switch cabinets usually assigned to a machine tool are designated 28 and 29.

Abstract

Plusieurs unites d'usinage (6, 7, 8) qui sont orientables simultanement au moins dans trois axes, sont disposees autour d'une table centrale (1) d'une machine-outil, cette table pouvant etre indexee de maniere continue ou pas a pas; la piece a usiner qui est solidement centree sur le support, peut etre usinee simultanement sur plusieurs de ses faces. La piece a usiner est toujours deplacee ensemble avec le support sur la table et, hors de celle-ci, l'echange d'un support portant une piece a usiner determinee contre un autre support avec une autre piece a usiner, a lieu sur une unite d'echange. Au centre de la table (1), est prevu un dispositif (23) d'echange d'outils, avec l'aide duquel les outils, utilises dans toutes les unites d'usinage, sont pris hors d'un magasin (14) dispose tout autour du dispositif d'echange (23). Un dispositif commun de commande (28, 29) commande les mouvements des unites d'usinage, de l'unite d'echange des supports de pieces a usiner et du dispositif d'echange des outils.
