Abstract

192,273. Green, E. R. Jan. 23, 1922. Face-plates. - A face-plate for holding bored work, such as a wheel blank in a gear-cutting machine, is provided with a tapered member, movable normally to the face of the plate so as to co-operate with the edge of the base to centre the work. The face-plate 1 is bored at 3 to receive a tapered member 9 which is pressed by a spring 8 against a stop-nut 14 on a rod 7 screwed into the upper end of a central pin 5 extending from the base 4. The pin 5 is provided with an enlargement 6 to guide and support the member 9 in the vicinity of the work 22. The work is placed on the tapered member which is forced down when the work is clamped to the plate by a nut 16 and slotted washer 17. Bolts and straps may be used in conjunction with T- slots to fix the work more securely. For use with work having a large range of bores, a series of members of different taper may be used separately as required to keep the height of the tool low, Fig. 3 showing a form in which a flat annular platform 26 is formed between the conical surface and the cylindrical bearing surface 11. If the part 25 of the work is smaller than the bore 3 and there is no other machined surface to co-operate with the face-plate, a flat machined washer may be interposed between the work and the plate. A recess 19 and holes in the face-plate are provided for registering and fixing the tool to a back plate, which can be bored and screwed to fit a machine tool head, or formed with a spigot to register with the central base of any existing worktable.
