Apparatus for manufacture and repair of tubular products

Details

Inventors: Nugier, John G.;
Assignee: Rockwell International Corporation (Pittsburgh, PA)
Primary Examiner: Briggs; William R.
Assistant Examiner:
Attorney, Agent or Firm:

Apparatus useful in the manufacture and repair of automotive drive shafts which includes a frame and an elongate support bed rotatably mounting a multiple jaw chuck for rotary movement, a generally cylindrical workpiece passage extending through the chuck and its bearings and a pedestal remote from the frame and mounting an additional workpiece support axially aligned with the chuck. Stringers rigidly connect the remote workpiece support to the frame and a plurality of devices are mounted and movable relative to the support bed for selectively effecting operations on one end of a tubular workpiece supported by the multiple jaw chuck with the other end of said tubular workpiece supported by the remote workpiece support mounted to the pedestal.

DETAILED DESCRIPTION The present invention provides an apparatus for machining and fitting one end of an elongated tubular workpiece comprising a frame, an elongate support bed and bearing means rotatably mounting a multiple jaw chuck for rotary movement around a horizontal axis.
The bearing means are rigidly secured at one end of the support bed and means for rotating the chuck are also provided.
A generally cylindrical workpiece passage concentric with the horizontal axis extends through the chuck and the bearing means.
A tool head is supported by a stanchion at the other end of the support bed, and is mounted for reciprocating movement along the horizontal axis.
A laterally moveable tool fixture is also mounted for movement along one horizontal edge of the support bed between the multiple jaw chuck and the stanchion whereby the multiple jaw chuck, the tool head and the tool fixture may be selectively actuated to operate on one end of a tubular workpiece supported by the chuck in the workpiece passage with one end of the workpiece located on one side of the multiple jaw chuck between the multiple jaw chuck and the stanchion and the other end of the workpiece disposed on the other side of the multiple jaw chuck.
In the preferred embodiment the tool head is a vise fixed to a piston of a hydraulic cylinder supported by the stanchion, and the apparatus also includes means for withdrawing elements previously fitted to one end of the tubular workpiece.
The means for withdrawing elements previously fitted to one end of the tubular workpiece is preferably in the form of an additional chuck assembly movably mounted to the support bed and movable from a position displaced from the multiple jaw clutch to a position adjacent the multiple jaw chuck with the jaws of the additional chuck assembly concentric with the horizontal axis.
The additional chuck assembly also includes means for engaging the jaws of the additional clutch assembly with an element previously fitted to the one end of the tubular workpiece and means for moving the jaws of the additional clutch assembly and said element axially away from the end of the tubular workpiece
