摘要： A machine tool includes: a lower tool rest on which a plurality of tools are mounted; a motor provided at the lower tool rest, for rotating a rotating tool when the rotating tool is mounted on the lower tool rest; and a tool holder attached to the lower tool rest, for detachably holding the tool. The tool holder has a clamping mechanism portion operating between a clamping state of clamping the tool and an unclamping state of unclamping the tool, as a result of transmission of motive power generated at the motor. With such a configuration, the clamping mechanism portion for automatically clamping and unclamping the tool held in the tool holder on the tool rest is provided with a simple configuration.

摘要： A turret includes a housing connected to a machine tool, a rotatably mounted toolholder for mounting of machining tools, and an electric drive for rotating the toolholder into a particular working station for the machining tools. The electric drive has a rotor and a stator with coil windings. The rotor of the electric drive is connected to the toolholder. The stator is connected to elements of the housing. The rotary movement for the toolholder is generated without gearing and directly by the electric drive of the rotor enclosing the stator. Since both the rotor and the stator are enclosed by the toolholder and since the rotor is in direct contact with the toolholder on the side of the external circumference and rigidly connected to the toolholder for transmission of torque, the rotor-stator layout creates an external rotor for the electric drive. In that layout, the rotor rotates externally, with the tool holder and the stator being mounted internally of the housing.

摘要： The present invention is directed to an indexing tool turret assembly and method for operating the same. The indexing tool turret assembly includes a tool turret assembly rotatably supported on the machine tool, an indexing assembly for selectively rotating the tool turret assembly to a desired location. The indexing assembly includes a locking assembly to prevent rotation of the tool turret assembly during operation of either a stationary tool assembly or live tool assembly located on the tool turret assembly. A cushioning bearing assembly is provided for selectively separating the tool turret assembly from the locking mechanism during an indexing operation. The cushioning bearing assembly provides a slight lift to separate the tool turret assembly from the locking mechanism to reduce friction and other potential damages forces between these components.

摘要： In accordance with the present invention, there is provided a cutting tool having a cutting tool insert which is automatically rotationally indexable. The cutting tool includes a shank and an indexable cutting tool insert rotatably connected to the shank. The insert includes a plurality of cutting edges and side surfaces therebetween. The cutting tool is also provided with an indexing device, lock pin, cam plate and eccentric cam pin. The indexing device comprises a sliding key and a pair of spring metal legs attached thereto for engaging a serrated portion of the lock pin to which the cutting tool insert is attached. The indexing device is effective for indexing the insert on the lock pin upon rotation of the cam pin which effects a lateral movement of the cam plate along the longitudinal axis of the shank whereby the cam plate engages the sliding key causing it to also move laterally to engage the indexing legs on the lock pin resulting in rotation of the lock pin and the cutting insert attached thereto.

摘要： The specification is directed to a method of operating a machine tool which enables a machining center, a transfer line or a flexible manufacturing system to be rapidly converted from the manufacture of one work piece to the manufacture of another workpiece. This is achieved by mounting all the tools associated with one series of machining steps on a common carrier unit and adapting the carrier unit so that it can be placed quickly in position on the machine tool and automatically centered in a variety of positions so that each of the individual tools can be brought into a desired machining relationship with the workpiece. The tools can comprise both stationary and driven tools and the machine tool is adapted to allow relative movement between the workpiece and the individual tools so as to carry out the desired machining steps. The tools can be preadjusted in their mounts before the carrier unit is placed on the machine tool and are to be stored already mounted on the carrier units to avoid tool losses when not in use. During machinery the tools preferably remain in the mounts but in one embodiment tools can be withdrawn from the mounts and transferred to a machining head. The carrier units are preferably of bell-like form and located on machine tools by means of a pair of mating Hirth rings.

摘要： A turret indexing system for a turret punching machine having a plurality of equally spaced tool punching stations carried on the turrets which may be rotatably positioned to place selected punching tools in register with a punching ram. Turret indexing is accomplished with a pneumatic cylinder driven reciprocating drive arrangement utilizing a pneumatically actuated clutch to drive the turrets through a one direction, incremental indexing rotation which is equivalent to one tool punching station spacing. A shot pin arrangement is effective to lock the turrets in an operating position and provide small corrective repositioning of the turrets, when required, to precisely position the turrets relative to the punching ram. A control system provides an automatic sequenced cycling of the indexing system to position each required punching tool in an accurate punching position.

A gear member is rotatably but non-slidably mounted on the support shaft and is provided with a threaded portion threadedly engaged with the base. A sleeve member having a rack engaging with the gear member is moved axially to lift the tool support to an upper position for an index operation. The sleeve member is provided with a notch to receive a resiliently urged lock shaft for restraining the axial movement of the sleeve member when the tool support is moved to the upper position.
