Abstract

806,399. Gear-finishing; chucks. NATIONAL BROACH & MACHINE CO. March 29, 1957 [May 28, 1956], No. 10327/57. Class 83 (3). A method of loading an internal-gear G into a gear-finishing machine consists in supporting the gear G on the tool T in mesh therewith, and relatively moving the tool and a chuck 30 until the gear is within the chuck, where it can be clamped. The chuck is rotated on a head 16 and the tool T is carried on a slide 22 reciprocable on a vertically-adjustable knee 12. The gear is clamped by three dogs 48 on rods 46 which are moved by arms 40 attached to the head 39 of a pneumatically-operated draw-bar 36. Each rod 46 is helically slotted to engage a fixed pin 56 which rotates the dog out of the path of the gear when the draw-bar is moved forwardly to engage ejector pins 60. An ejected gear is caught by springs 62 and removed manually. A gear to be finished is first placed on the tool and is then clipped under a spring 78 on a locating-device 68, 72 secured to the toolspindle support 66. The locating device also has two fingers 76 which prevent rocking of the gear but do not normally come into contact therewith. When the gear has been moved towards the chuck, it is pulled thereinto by the dogs 48, the parts then being in the positions shown in Fig. 3, which is a view from below. The fingers 76 may extend on the outside instead of within the chuck, the dogs. 48 may be radially movable instead of swinging, and the tool, instead of the work, may be rotated.
