Abstract

Abstract An indexable tool turret for use in a machine tool having an automatic tool changer. The turret has two tool stations, both of which have a motor operated clamp for securing a tool in the station with a locating surface of the tool clamped against a locating surface of the turret. Each station has a plurality of air jets directed at the tool when it is inserted into the station so that dirt and debris are blown clear of the tool and particularly its locating surfaces automatically as the tool is inserted into the station. Indexing of the turret is effected by lifting the tool turret clear of a gear coupling and rotating the turret to a new index position after which it is lowered to reengage the gear coupling. A hydraulic motor raises and lowers the turret and functions as a relatively friction free hydraulic thrust bearing to support the turret in the raised position while it is indexed.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 129 words
For use in combination with a machine tool having an automatic tool changer, a tool holder having a socket for the reception of interchangeable tools, clamping means mounted upon said tool holder and operable to clamp tools in said socket of said holder with a locating surface of the clamped tool abutting against a locating surface of said tool holder, the improvement which comprises: a plurality of air jet orifices located around the periphery of said socket, said orifices being directed at a tool as it is moved into said socket, and means for supplying air at a pressure above that of the atmosphere to said orifices when a tool is inserted into said socket so as to blow dust and debris away from the surface of said tool.
Claim 2
Dependent Claim 129 words
For use in combination with a machine tool having an automatic tool changer, a tool holder having a socket for the reception of interchangeable tools, clamping means mounted upon said tool holder and operable to clamp tools in said socket of said holder with a locating surface of the clamped tool abutting against a locating surface of said tool holder, the improvement which comprises: a plurality of air jet orifices located around the periphery of said socket, said orifices being directed at a tool as it is moved into said socket, and means for supplying air at a pressure above that of the atmosphere to said orifices when a tool is inserted into said socket so as to blow dust and debris away from the surface of said tool.
Claim 3
Dependent Claim 18 words
The tool holder of claim 1 wherein said orifices are directed inwardly toward the centerline of said socket.
Claim 4
Dependent Claim 26 words
The tool holder of claim 1 wherein said socket is circular in cross section and said orifices are directed radially toward the axis of said socket.
Claim 5
Dependent Claim 127 words
For use In combination with a machine tool having an automatic tool changer, a tool holder having an enclosed socket for reception of interchangeable tools, clamping means mounted upon said tool holder and operable to clamp tools in said socket of said holder, air orifice means opening into said socket, and means for supplying air at a pressure above that of the atmosphere to said orifice while a tool is being inserted into said socket so as to form a pneumatic self-centering bearing between said tool and the surface of said socket during said tool insertion including said air orifice means opening into said socket and means for supplying air at a pressure above that of the atmosphere to said orifice during tool insertion into said socket.
Claim 6
Dependent Claim 127 words
For use In combination with a machine tool having an automatic tool changer, a tool holder having an enclosed socket for reception of interchangeable tools, clamping means mounted upon said tool holder and operable to clamp tools in said socket of said holder, air orifice means opening into said socket, and means for supplying air at a pressure above that of the atmosphere to said orifice while a tool is being inserted into said socket so as to form a pneumatic self-centering bearing between said tool and the surface of said socket during said tool insertion including said air orifice means opening into said socket and means for supplying air at a pressure above that of the atmosphere to said orifice during tool insertion into said socket.
Claim 7
Dependent Claim 25 words
The tool holder of 4 wherein a plurality of air orifices open into said socket and are directed inwardly toward the centerline of said socket.
Claim 8
Dependent Claim 25 words
The tool holder of 4 wherein a plurality of air orifices open into said socket and are directed inwardly toward the centerline of said socket.
Claim 9
Dependent Claim 26 words
The tool holder of claim 5 wherein said socket is circular in cross section and said orifices are directed radially toward the axis of said socket.
