  • the first hand 73 and the second hand 75 are connected to the first main spindle 7 and the second hand 75 while avoiding contact between a part of the work transfer device 33 such as the swing arm 59 and the upper turret tool post 17 and the lower turret tool post 19.
  • the second main shaft 13 can be approached. Further, it is possible to sufficiently suppress the swing range of the swing arm 59 (that is, the workpiece transfer device 33) from being widened. In particular, since the swing arm 59 has a curved shape with its center protruding forward, it is possible to more sufficiently suppress the operation range of the work transfer device 33 from being widened.
  • the storage space of the swing arm 59 can be minimized and the vertical slider 51 in the cover 21 can be minimized.
  • the slide space in the vertical direction can be used as a storage space for the swing arm 59.
  • the swing motor 63 and the vertical motor 53 are arranged vertically, the length of the Z-axis slider 39 in the Z-axis direction can be shortened.
  • the first hand 73 and the second hand 75 are connected to the first spindle 7 and the first hand 75 while avoiding contact between a part of the work transfer device 33 and the upper turret tool post 17 and the lower turret tool post 19.
  • the two main shafts 13 can be approached. For this reason, even if the machine tool 1 that processes the material workpiece WA from above is equipped with the workpiece transfer device 33, the material workpiece WA is loaded into the first spindle 7 and the product workpiece WB is unloaded from the second spindle 13. Can be done.
  • the machine tool 1 can be reduced in size.
  • the vertical slide space of the vertical slider 51 in the cover 21 can be used as the storage space for the swing arm 59 while minimizing the storage space for the swing arm 59, and the Z-axis slider 39 Since the length in the Z-axis direction can be shortened, the machine tool 1 can be further downsized.
  • this invention is not limited only to the said embodiment, It can implement in a various aspect. Further, the scope of rights encompassed by the present invention is not limited to the above-described embodiment.

Abstract

L'appareil de transport de pièce à travailler selon l'invention effectue la mise en place d'une pièce à travailler de matériau sur la broche principale d'une machine d'usinage et réalise le mouvement de la pièce à travailler de produit sur la broche principale. L'appareil de transport de pièce à travailler est doté : d'une poutre de support s'étendant le long de la direction de l'axe Z, qui est parallèle au centre axial de la broche principale ; un patin sur l'axe Z monté sur la poutre de support ; un patin vertical monté sur le patin de l'axe Z ; un bras oscillant raccordé à l'extrémité avant du patin vertical ; ainsi qu'une première main et une seconde main placées sur le bras oscillant. En faisant coulisser le patin de l'axe Z dans la direction de l'axe Z, le patin de l'axe Z, le patin vertical, le bras oscillant, la première main et la seconde main sont placés à l'intérieur du capot de la machine d'usinage ou sortis dudit capot. En utilisant cet appareil de transport de pièce à travailler, la mise en place et le mouvement des pièces à travailler peuvent être effectués de manière convenable, et la machine d'usinage peut être plus petite.
