Abstract

829,366. Gear-cutting. CHURCHILL GEAR MACHINES Ltd. Feb. 12, 1958 [Feb. 15, 1957], No. 5264/57. Class 83 (3). A hobbing-machine comprises a vertically and angularly-movable transfer member 50 for transferring a workpiece between a conveyer and a work-table. The blanks are fed along one side of the machine by a chain having transverse rods 14 which engage the blanks. The rods 14 are also engaged in succession by a spring- loaded pawl on an hydraulic ram 16, which is reciprocated to advance the chain. The transfer member comprises two pivoted jaws 52, 53 slotted to engage pins 49 carried by an hydraulic piston 34. The piston is carried on a vertically-movable hydraulic piston 26 which carries, at its lower end, a vane 42, oscillatable between fixed stops by hydraulic pressure. In operation, with the conveyer loaded with blanks, the piston 34 is operated to close the jaws on a workpiece, and fluidpressure is supplied in succession against the piston 26 and vane 42 to raise the blank and swing it to a position above the work-holder. As the piston rotates, a dog actuates a switch to lower the piston and the blank is then released by the jaws. After the blank has been hobbed, the gear is gripped, raised and swung-back over the conveyer. It is then lowered and released, the release movement of the jaws actuating a switch to reciprocate the piston 16 and bring another blank into position. Finished gears fall down a shoot 23.
