Abstract: A tool revolver, in particular for a machine tool, includes a tool disk (1) rotatable about a revolver axis and provided with a plurality of tool stations distributed along the disk circumference and movable to an operation position by the disk (1) rotation. At least one part of the tool stations (13) has a reception area (25) for receiving a tool holder (3). A fixing device is used for fixing a corresponding tool holder (3) at a defined position in the reception area (25). The interaction between an elastic adjusting body (31) protruding perpendicularly to the reception area (25) and used in the form of an orientation element for positioning and adjusting surfaces (41, 43) deepened into a base surface (7) of the tool holder (3) enables the tool holder to take an adjustment position when a screw fitting is fastened.

Abstract: A sealing arrangement (41) sealing the inside (15) of the tool disk (3) in relation to the outer side on the respective tool station is provided on each drive part (25) in a tool revolver. The tool driver a base body (1) applied or to be applied to the tool machine and defining a revolver axis (7) about which a tool disk (3) is rotationally mounted on the base body (1). The tool disk has a plurality of tool stations (17) distributed on its periphery and adjustable by rotating to tool disk (3) in respectively at least one working position. A tool drive (19) located in the inside of the tool disk (3) and applied to the base body (1) is coupled to the drive-sided coupling part (23). The coupling part includes a tool-sided coupling part for the drive of a tool located on the tool station (17) oriented towards the work station.

Abstract: A sealing arrangement (41), which seals the inside (15) of the tool disk (3) in relation to the outer side on the respective tool station, is provided on each drive part (25) in a tool revolver comprising a base body (1) which is applied or is to be applied to the tool machine and which defines a revolver axis (7), about which a tool disk (3) is rotationally mounted on the base body (1). Said tool disk comprises a plurality of tool stations (17) which are distributed on the periphery thereof and which can be adjusted by rotating to tool disk (3) in respectively at least one working position, wherein a tool drive (19), which is located in the inside of the tool disk (3) and which is applied to the base body (1), is coupled to the drive-sided coupling part (23) comprising a tool-sided coupling part for the drive of a tool, which is located on the tool station (17) which is oriented towards the work station.

Abstract: The invention relates to a tool revolver, in particular for a machine tool, comprising a tool disk (1) which is rotatable about a revolver axis and provided with a plurality of tool stations which are distributed along the disk circumference and can be moved to an operation position by the disk (1) rotation, wherein at least one part of said tool stations (13) comprises a reception area (25) for receiving a tool holder (3) and a fixing device is used for fixing a corresponding tool holder (3) at a defined position in the reception area (25), respectively. The interaction between an elastic adjusting body (31) which is protruded perpendicularly to the reception area (25) and is used in the form of an orientation element for positioning, and adjusting surfaces (41, 43) deepened into a base surface (7) of the tool holder (3) enables the tool holder to take an adjustment position when a screw fitting is fastened.

Abstract: 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.

Abstract: The invention relates to a tool head with a spindle bearing arrangement The bearings (9, 10) of said arrangement rest with one of their bearing shells on a driven spindle (2) with a tool holding fixture (1). With their other bearing shell they interact with a housing (8) in such a manner that in at least one part (10) of the bearings (9, 10) the respective other bearing shell interacts with a sliding piece (11) which is slideable along the housing (8) in the one sliding direction and which locks the spindle (2) with the housing (8) in a locking position. In the other sliding direction, said sliding piece releases the spindle in a release position. The invention provides a universally useful tool head by the following configuration: The respective other bearing shell of the one part (10) of the bearings (9, 10) is at least partially enclosed by the sliding piece (11). Said sliding piece (11) is forced into the locking position with a predetermined contact force by a drive device.

Abstract: In the dust extraction appliance for flat knitting machines, a vacuum is generated in the suction nozzles (17) by means of at least one suction-flow device (16) which is arranged on the slide of the flat knitting machine and into with a conveyed, via a flexible delivery line (20), compressed air which carries the sucked-up dust further into a dust collecting bag (18) via an exhaust-air duct (22).

Abstract: The dust extraction device located on the cam carriage (13) of the flat knitting machine has separate, independently operable suction fans (27) for the front and rear needle beds (11,12), which, by lowering of the suction nozzles (29,30), the use of smooth-walled suction ducts (31,32) and coupling of the dust containers (37) with the suction ducts and with the suction fans (27) ensures a good cleaning effect with low expenditure of energy and a maintenance free operation.
