Abstract

880,122. Gear-cutting. CHURCHILL GEAR MACHINES Ltd., MILLS, J. A., and WEDGWOOD, P. June 15, 1960 [April 22, 1959], No. 13671/59. Class 83 (3). A hobbing machine comprises a feed magazine with means 34 for positioning each blank in a definite angular position, gripping jaws 37a for transferring a workpiece 38 from the magazine to a cutting position, and means for stopping rotation of the workpiece after hobbing is complete, with the workpiece in a definite angular position, the hobbed gear being returned to the same position on the magazine as it previously occupied. The camshaft blanks 38 are carried between discs 14, 19 indexed by a fluid-pressure-operated ratchet moved when a hobbed workpiece has been replaced. The ratchet engages teeth 23 on a disc 22 which is formed with locating holes 24. The lower end of each blank is located by a pin 34 and a wall 33. The magazine is supported by arms 10, 11 mounted on tailstock ways 10a. A transfer unit, including the jaws 37a, as described in Specification 829,366, lifts a cam-shaft off its mounting and transfers it on to a mounting 40. The tailstock 42 holds a workpiece against the mounting 40 which has a locating and driving pin or key 41. Hydraulically-operated jaws 46 steady the workpiece during hobbing. The work-head carries a cam which contacts a switch on the hob-slide as the bobbing operation is completed to stop the work in a particular position. The magazine may be in the form of an endless conveyer. The upper disc 14 may be omitted for short workpieces.
