A high-pressure cutting fluid guide apparatus of a turret head of a machine tool is provided. When a high-pressure cutting fluid is input to a cutting liquid passage, the high-pressure cutting fluid flows along a through hole of a water guide cylinder, and passes through a main perforation of a partition, and then flows to a water outlet of a sealing ring to be guided into a water inlet of a cutting disc. A secondary perforation of the partition guides the high-pressure cutting fluid in the through hole to a press surface portion of the sealing ring. The sealing ring is located in an annular trough, and the press surface portion is pushed by the high-pressure cutting fluid pressure to generate the energy of the axial displacement.

A turret tool post includes a turret turnably supported by a post body, turret turning part having a turret turning shaft and the like to turn the turret, a tool attachment part turnably holding a rotatable tool and attached to the turret, and tool-attachment-part turning part turning the tool attachment part to turn the rotatable tool. The tool-attachment-part turning part and the turret turning part are provided independently and arranged to face each other. The tool-attachment-part turning part includes a tool turning motor installed inside the turret and an attachment-part transmission shaft connected to the tool turning motor.

A machining head is provided with a turret on which multiple rotating tools are mounted, and this head is configured such that rotation of each of the multiple rotating tools during machining and rotation of the turret are performed by a single motor. A switchable turret rotation transmission mechanism is disposed to be capable of transmitting the rotation of the motor shaft to the turret as the rotation of the turret and releasing the transmission. The rotation of each of the multiple rotating tools during the machining and the rotation of the turret can be performed by the single motor.

A tool turret includes a tool disk (1) having at least one tool receptacle (7) for a machining tool and being fastened to an accommodating disk (51). The disk can be swiveled about a support column that defines a swivel axis into positions in which the particular machining tool is in a working position. A contact surface (55) is provided on the tool disk (1) and can be clamped to an accommodating surface (53) on the accommodating disk (51) by a clamping device. The clamping device has an annular groove on one disk to be clamped. The annular groove is concentric to the swivel axis, is open radially outside and has at least one inner slanted surface (81). At least one compression piece (57) is on the other disk, penetrates the annular groove (61) under compressive force and has a wedge surface (79). In interaction with the slanted surface (81) of the annular groove (61), the wedge surface produces a force component as a clamping force from the compressive force pressing the contact surface (55) and the accommodating surface (53) against each other.

A tool exchanger includes a variation detection unit configured to detect a variation periodically generated by turning operation of a turret; and a turret phase detection unit configured to set a tool indexing reference phase of the turret based on a detection result from the variation detection unit.
摘要:
An automatic rotating turret device for work machinery is provided, in which a lift turret is not used. The turret device is provided with an axial-direction slide body, which is advanced or retracted in the direction of the axis of rotation of the turret by the drive device advancing or retracting the drive body in a direction orthogonal to the direction of rotation axis; and a clutch device that is engaged or disengaged by the axial-direction slide body being advanced or retracted, the turret being of a non-lift-type, and there being provided to the drive body a tapering action part for generating an expanding action caused by the movement of the drive body and pressingly sliding the axial-direction slide body against the turret stage.

A tool turret for machining workpieces has a housing and with a part that can be rotated around an axis of rotation into several rotary positions. On the rotating part, several tool holders are mounted on the circumference for holding tools to which a cryogenic cooling medium can be fed by means of a first feed line and a respective second feed line. The first feed line can be moved in a linear manner in at least some sections by linear actuator whereby the first feed line is connected in a first position with the second feed line belonging to the tool in work position and in a second position is disconnected from the second feed lines for changing the rotary position of the rotating part. The tool turret enables the cryogenic cooling medium to be fed to the tools in a simple and reliable manner.

An automatic screw machine (20) has a body (22), and a head (21) that is rotatably mounted on the body and that is adapted to be selectively rotated relative to the body between any of a plurality of index positions. The body and head have closely-spaced and facing bearing surfaces (25, 28 and 26, 29), have spindles (23) journalled on the head for rotation relative thereto, and have a source of pressurized lubricant. The improvement broadly includes: at least one body passageway (32) communicating the source with the body bearing surface, the intersection of each body passageway with the body bearing surface defining a body port (33); a head passageway (36) communicating the head bearing surface with the spindle, the intersection of said head passageway with said head bearing surface defining at least one head port (42); and the body and head passageways being so configured and arranged such that lubricant may flow from the source to the spindle only when the head is in the vicinity of the index position such that the body and head ports overlap one another.
