Operating head for machine tools characterised in that it comprises:
a first support to be mounted on a machine tool a second support
mounted on the said first support in such a way that it can rotate
around a first axis a tool holder mounted in a cavity present in
the said second support in such a way that it can rotate around
a second axis that does not coincide with the said first axis, in
particular an axis orthogonal to the said arms which lies on the
same plane as the said first axis. This solution offers various
advantages, including an operating head which is much simpler to
manufacture and therefore cheaper than known types, as well as a
considerable simplification of the machine control software.
In order to improve a tool support for machine tools comprising
a base unit, a holding member which is arranged on the base unit
and on which two supporting surfaces extending at an acute angle
to one another are arranged for supporting a tool holder in a first
supporting area and a second supporting area, and a clamping device
for acting on a clamping member of the tool holder in a clamping
direction extending in such a manner that the tool holder acts upon
the supporting surfaces with the first and the second supporting
areas, in such a manner that clamping of a tool holder is possible
in as simple a way as possible it is suggested that the clamping
element be mounted in the holding member for rotation about an axis
and bear a wedge surface movable on a path around the axis for acting
on the clamping member, and that the wedge surface of the clamping
element engage over the clamping member proceeding from an insert
position during the rotation of the clamping element in a first
direction of rotation and act upon this clamping member so as to
displace it increasingly in the clamping direction.
A self-feeding shredding device, particularly for liquid lubricant/refrigerant
filtration plant for machine tools with swarf removal, incorporating
a channel element in which a motorized screw conveyor sits, having
one end of reduced diameter that passes through an internally grooved
cylindrical body. A lobe rotor is axially faced up against the outside
of the grooved cylindrical body and its rotation controlled by the
screw conveyor. The swarf, unwound and stretched out from the reduced
diameter end tip of the screw conveyor along the grooved cylindrical
body, is pushed towards the lobe rotor and shredded.
This invention relates to a chuck unit for automatic machine tools,
designed to perform both power tasks and high-speed finishing of
pieces, with lubricant/coolant fluid flowing through the chuck shaft,
which includes: a support (1) on which a chuck (4) for a power tool
is mounted, the said chuck being driven by a first motor (2) a second
chuck (5) mounted inside the previous one and coaxial with it, which
is driven by a second independent motor (18), means (12) designed
to discharge the pull of the power tool (4) onto the said support
being fitted. The result is a unit which can receive different types
of tool and perform different types of task, for which it has so
far been most advantageous to use two separate machines.
