Pipe End Machining Device with Axial Autofeed

A device for preparing the end of a pipe includes a non-rotatable mandrel one end of which is attachable to the pipe. A motor rotates a sleeve around the mandrel and the sleeve retains an arm perpendicular to the mandrel for cutting the pipe. A cam surface on the rotating sleeve moves a cam follower. Movement of the cam follower is converted to rotational movement for turning a feed nut threaded on the mandrel. The rate at which the sleeve is advanced by the feed nut is controlled by limiting the movement of the cam follower.

On-vehicle disk brake lathe

A disk brake lathe has a pair of tool bits mounted to tool holders which are translatable parallel to a lathe axis to adjust the separation of the tool bits from a brake disk. A displacement gauge responds to changes in the separation between the tool holders. When the tool bits are in continuous contact with the disk, the separation indicates the thickness which would result from machining the disk. This separation can be compared to a specification to determine whether to machine or discard the disk. A method for machining a disk starts by mounting and aligning the lathe to a wheel hub on which the disk is mounted. The tool bits are each advanced until they are in continuous contact the disk surfaces, when the separation of the tool bits is measured and preferably compared to a specification. When the tool bits are sequentially advanced, variation in the separation can be used to determine depth of cut for each tool bit. A system employing a brake lathe has a microprocessor which receives signals responsive to the separation between the tool bits of the lathe. One or more contact sensors indicate contact of the tool bits with the other tool bit or the brake disk, and the microprocessor can implement instructions to practice the above method. A surface displacement gauge can be employed to allow the system to measure the thickness and lateral run-out of the disk prior to machining.

Pipe beveling system

A tool for beveling the end of a pipe is comprised of a hollow, tubular body having a central, longitudinal axis of rotation, an inboard coupling end, and an opposite outboard working end. A plurality of longitudinally spaced, transversely directed latching pin bores of equal size are defined through the wall of the tubular body. A core member is disposed coaxially within the tubular body. The core member includes a beveling cutter head and a longitudinal stem having a radially inwardly directed, circumferential latch position groove. A transversely oriented latching pin is engaged in a selected one of the latching pin bores in the body and with the latch position groove of the core stem. This allows alternative selection of each of the latch position bores for insertion of the latching pin. The particular bore selected determines the longitudinal position of the core stem latch position groove within the body that will be aligned with the latching pin. This, in turn, determines the extent of protrusion of the core member cutter head from the outboard end of the tubular body, and thus the depth of the beveling cut in the pipe.
