Abstract

1346589 Bar - stock feed; grinding TWYFORD MOTORS (AIRCRAFT & ENG) Ltd 4 Oct 1971 [22 Oct 1970] 50307/70 Headings B3B and B3D A bar holder arrangement for holding bar stock material to be fed to a machine tool comprises a frame and at least one elongated bar holder 106 mounted in the frame, the or each bar holder 106 comprising a plurality of levers 95 each pivotally mounted by bolts 96 on an elongated member 109, each of the levers 95 having upstanding members 119, 123 at its opposite ends with semicircular recesses therein, the levers being so disposed along the elongated member 109 that adjacent upstanding members 119, 123 of adjacent levers 95 define a circular receiving means for a length of bar stock material, and an actuating bar 125 which simultaneously pivots the levers 95 to move apart the adjacent upstanding members to allow a barstock to be dropped on to a resilient stop 126 and pivots the levers back again to support the bar stock. In the embodiment described six bar holders 106 are mounted on a reel that rotates in conjunction with a multi-spindle lathe head, to present one of the bar holders below a bar stock feed device. At this position only a pressure ram is able to operate a lever to actuate the actuating bar 125. The upstanding members 119, 123 on the levers carry nylon inserts that can be exchanged for different diameter bar stock. For long bar holders sections of bar holders 106 can be connected together.
