    摘要： An improved mandrel chuck for the backstop assembly of a friction welding machine holds a first interiorly lobed workpiece as a second rotating workpiece is displaced into forceful engagement therewith. The improved chuck comprises a main body portion, an end portion rigidly fixed to the main body portion, and an intermediate portion mounted between the main body portion and the end portion, all of the chuck portions having similar exterior lobes in a configuration which complements the interior lobes of the first workpiece. A hydraulic actuator rotates the intermediate portion relative to the main body and end portions to interiorly grip the first workpiece wherein one end of the first workpiece projects from and is proximate to the chuck end portion, whereby the chuck will not contribute to any outward bowing or distortion of the workpiece end.

    摘要： A loader (12) for a spline rolling machine wherein die and mandrel teeth (26,42) mesh with the thinwall sleeve (44) of a power transmission member (30) located therebetween to form splines therein is disclosed as including a loading member (58) with a locator (68) on a rotatable clamp (66) thereof and as including an unloading member (60) having a depression (72) that receives the locator (68) so as to permit clamping of an end wall (46) of the power transmission member (30) in an accurately located relationship while still ensuring disengagement during unloading upon movement of the loading and unloading members (58,60) away from each other at an associated load table (36). The locator (68) preferably has a detachable connection (88) to a housing (78) of the rotatable clamp (66) on the loading member (58), and the unloading member (60) includes a shaft (98) and an enlarged head (100) secured to the shaft by a detachable connection (102,104) in order to facilitate loading and unloading of different size power transmission members by merely replacing the locator and the enlarged head. Clamping surfaces (70,74) on the loading member clamp housing (78) and the enlarged head (100) of the unloading member clamp the power transmission member (30) during the loading and unloading.

    摘要： This application discloses a work-holding chuck particularly for gears with their exterior teeth finished or substantially finished as by grinding, shaving and the like. This chuck has a plurality of hardened and finished pins which are moved and secured in a precise circular array and arranged as pairs on a ring member. A stop is provided so that the gear and the hub portion thereof is precisely located and positioned. Sliding segments are moved along a ramp guide by pneumatic or hydraulic means to bring the formed pins into the formed flanks of the teeth profile to repeatedly and precisely hold the gear by its formed and finished teeth. The held gear is now finished in its bore. Means are provided for readily changing the pins and position of these pins on the chuck so that gears of different pitch, number of teeth and/or lead may be accommodated.
