Abstract

1,217,326. Tool or work feeding devices. NATIONAL RESEARCH DEVELOPMENT CORP. 28 Feb., 1968 [23 Feb., 1967], No. 8740/67. Headings B3B and B3T. A tool or workpiece feeding device in a machine tool comprises a housing 5 in which is rotatably mounted a first unit 21 which carries a second rotatable unit 25, the axes of rotation 23, 27 of the respective units being parallel and offset, the second unit 25 carrying a tool or workholder 9 which is rotatable about an axis 9 parallel to and offset from the axis of rotation 27 of the second unit, the units 21 and 25 being independently driven through separate gear trains by hydraulic motors 31, 43 respectively. The relative movement between the units 21, 25 permits the tool or workholder to be positioned at any desired point within an annular region defined by the dotted lines 31. In the particular embodiment described the workholder in the form of a chuck 9 carrying a workpiece 7 and by controlled movement of the units 21 and 25 the workpiece is presented to one or more selected stationary cutting tools 11, 13, 19 mounted on the casing 1 of a machine tool in which the device is located. An electric motor 61 is provided on the housing 5 which drives swash-plate type pumps (95) and (114), Figs. 4 and 6 (not shown), pump (114) providing a source of hydraulic fluid for servo units 99, 107 for actuating the motors 31 and 43 respectively. The output from the pump (95) provides a source of hydraulic fluid for driving a motor (103) within the unit 25 for rotating the chuck 9 with the workpiece 7, the workpiece being reciprocated parallel to the axis 9 to effect machining thereof.
