摘要:
A method and apparatus for automated loading and unloading of a cylinder (14) in an engraver (10). The method and apparatus permit the engraver (10) to accommodate cylinders (14) of differing geometries, including a range of lengths, diameters and mounting configurations. The engraver (10) comprises a headstock (16) and a tailstock (18) which cooperate to rotatably support a cylinder (14) at an engraving station (15) in the engraver (10). The engraver (10) also comprises a cylinder handling system having at least one cylinder support (30) for supporting the cylinder (14) between the headstock (16) and tailstock (18) during loading and unloading of the cylinder (14). The cylinder handling system comprises a driver (32) for driving the cylinder support (30) towards and away from the engraving station until the headstock (16) and tailstock (18) engage and rotatably support the cylinder (14). Once the cylinder (14) is rotatably supported between the headstock (16) and tailstock (18), then the cylinder support (30) is retracted. Each cylinder support (30) comprises a telescoping support member (34) having a support nest (36) for engaging and supporting the cylinder (14) at the engraving station (15).

La machine d'usinage (10) comporte une première unité d'usinage comprenant une tête d'usinage (12) et des moyens (11) sous forme d'une pince pour amener, maintenir et déplacer axialement la matière à usiner. La tête d'usinage (12) porte des outils (13 et 14) rotatifs et mobiles selon deux axes X1 et X2 perpendiculaires à l'axe (15) de la matière. La machine comporte par ailleurs une tourelle principale (16) équipée de postes d'usinage (17) et de postes de prise en charge (18) des pièces. Selon une première option, elle comporte une deuxième unité d'usinage (22) portant des postes d'usinage (23). Selon une deuxième option, elle comporte une troisième unité d'usinage (24) portant un poste d'usinage (26) équipé d'un outil (25) éventuellement tournant. Selon une troisième option, la machine est complétée par une tourelle auxiliaire (20) portant des postes d'usinage (21).

Dispositif, pour la manipulation automatique de pièces à usiner sur un tour, comprenant une poutre (5) parallèle à l'axe de la broche (4) du tour, un chariot (12) agencé sur la poutre (5) et des moyens (14) pour le déplacer sur cette dernière, deux pinces (19), articulées autour d'un axe parallèle à l'axe de la broche (4), supportées par le chariot (12) et disposées de part et d'autre du plan passant par l'axe de la broche (4) et par l'axe longitudinal de la poutre (5), des moyens (24) pour déplacer chacune des pinces (19) pour les rapprocher et les écarter de l'axe de la broche (4) et des moyens pour ouvrir et fermer séparément chacune des pinces (19).
摘要:
Provided is a machine tool and a method for controlling the machine tool capable of precisely determine a success or a failure of a cut-off. An NC lathe 1 includes a first spindle 31 capable of moving in an axis direction thereof and a second spindle 61 capable of moving to a position facing the first spindle 31. The NC lathe 1 performs a cut-off of a workpiece W gripped by the first spindle 31 and the second spindle 61 and then performs a separation movement of the second spindle 61 in a direction separating from the first spindle 31. The NC lathe 1 further includes a movement controlling unit 211 adapted to perform a stop control of the first spindle 31 at a command position of the first spindle 31 during the separation movement of the second spindle 61 and a cut-off success or failure determining unit 213 adapted to monitor a positional deviation of the first spindle 31 during the separation movement of the second spindle 61 to determine a success or a failure of the cut-off, the positional deviation being a difference between the command position and an actual position of the first spindle 31.
摘要:
[Problem] To suppress displacement of the relative positions of a transport apparatus and a machine tool while suppressing a reduction in workpiece processing accuracy caused by vibrations of the transport apparatus. [Means to Solve Problem] A machine tool system 10 comprises: a machine tool 20 having a processor 220 to process a workpiece W with a tool 226, and a bed 210 on which the processor 220 is mounted; a transport apparatus 30 that has two, left and right, legs 31 arranged apart from the bed 210, that transports the workpiece W, and that feeds the workpiece W to the processor 220 or discharges the workpiece W from the processor 220; and a plate 60 that connects the bed 210 to the leg 31 and is elastically deformable. The plate 60 is arranged upright and such that a plate surface 62 is aligned with a front-rear direction, and a connection portion 66B of the plate 60 that connects with the bed 210 and a connection portion 66B of the plate 60 that connects with the leg 31 are displaced in a front-back direction.
摘要:
To provide a workpiece supply device (30) capable of supplying a workpiece (W) to be machined next in a supplying area of the workpiece (W) outside a machining area while the machining area is closed to control scattering of cutting fluid from the machining area during the machining of the workpiece (W). A machine tool (100) includes a machining room (2) of the workpiece (W), a loader room (3), a dividing wall (4) having an opening part (5), a main spindle (10), a workpiece supply device (30), a delivery device (20), and an ejection device (60). The workpiece supply device (30) includes a workpiece holder (31), a movement mechanism (32), a cover member (33), and a coil spring (40). The coil spring (40) biases the cover member (33) to close the opening part (5) by the cover member (33) such that the workpiece holder (31) holds the workpiece (W) in the loader room (3) during the machining of the workpiece (W) in the machining room (2).
