Tube Squaring Tool

US Patent:
5941145, Aug 24, 1999
Filed:
Nov 14, 1997
Appl. No.:
8/970198
Inventors:
Mark A. Marshall - El Dorado Hills CA
Marty E. Pound - Elk Grove CA
Assignee:
TRI Tool Inc. - Rancho Cordova CA
International Classification:
B23B 508
US Classification:
82113
Abstract:
A tube squaring tool includes a housing having forward and rearward end areas and a tubular workpiece clamping device located at the forward end area for securing and retaining a tubular workpiece relative to the housing so that the end of the workpiece can be machined by a rotary cutting head carried by the housing and movable towards and away from the end of the workpiece by manipulation of a feed mechanism. The tubular workpiece clamping device includes a pair of saddle members carried within a saddle mounting ring with one of the saddle members being frictionally secured within the mounting ring using a detent mechanism and the other saddle member being movable relative to the mounting ring and the opposing saddle member by a threaded connector that enables clamping of a tubular workpiece between the saddle members when the moveable saddle member is moved in a clamping direction towards the opposed fixed saddle member. Interchangeability of the saddle members to accommodate different size workpieces is facilitated by the friction coupling between one of the saddle members and the mounting ring and the saddle members are configured so that they may be readily removed and replaced through a radial retaining projection located on the forward end of the mounting ring.
