Abstract: A processing device includes a mounting base, a cutter holder, and a brake. The brake includes a driving member, a resisting member, and an elastic member. The driving member includes a main body and a driving shaft movably placed in the main body. The driving shaft is driven to move in a straight line by the main body. One end of the driving shaft is movably coupled to the cutter holder, and another end of the driving shaft is coupled to the resisting member. The elastic member is positioned between the main body and the resisting member. The driving shaft is configured to move toward one side of the driving member adjacent to the elastic member under an elastic restoring force of the elastic member, whereby the cutter holder moves with the driving shaft toward one end of the driving member adjacent to the elastic member.

Abstract: The invention described herein generally pertains to systems and methods related to repeatable and accurate setting of welding torch lead and lag positions, particularly with orbital welding systems. Specifically, a torch is coupled with a lead-lag coupler having a stop lug. A stop set with a stop pin is rotated to a desired position of lead or lag and secured. The lead-lag coupler, and torch which rotates therewith, are then unsecured and rotated until the stop lug contacts the stop pin. In this position, the torch is maintained at the desired angle. The stop pin remains in place throughout operation(s) to permit quick, accurate return to the desired angle if the torch is temporarily moved out of position.

Abstract: An embossing head for use in a rotary printing press has a raised embossing stamp, a constraining means for constraining motion of the embossing stamp along a radial direction, and adjustable positioning means for stopping radially downward motion of the embossing stamp at an adjustable lowermost position for determining an adjustable radial height of the raised embossing stamp. A number of embossing heads may be mounted independently to annular collars of the press to enable free positioning of the corresponding embossments in both dimensions of the sheet material. The adjustable positioning means enables fine height selection and adjustment of each embossing stamp individually so as to enable and facilitate the production of embossments on sheet material within specified tolerances reliably over numerous print cycles.

Abstract: A plunge base for a power tool includes a base plate having a generally flat bottom surface and defining an opening through which a router bit of a router supported by the plunge base extends to engage a workpiece. A carriage support extends vertically upward from the base plate on one side of the opening. A router carriage is slidably retained on the carriage support. The router carriage is slidable toward and away from the base plate between a first position and a second position and is configured to releasably secure a router thereto the router aligned with the opening in the base. A plunge lock mechanism is configured to retain the router carriage at any position between and including the first position and the second position in relation to the carriage support.

Abstract: A router guide having a work surface frame that defines upper and lower work surfaces. The guide further includes a tilting mechanism for tilting the router motor to a desired orientation with respect to a work piece, and a circular disc that is rotatably supported to the work surface to facilitate rotation of the circular disc. The router guider further includes multiple adjusting means, including, rotation means for frictionally rotating the work surface with respect to the router bit; adjusting means for slidably positioning the work surface along a first and second range of motion; and, adjusting means for positioning the work surface along a third.

Abstract: A three dimensional tool guide includes first, second and third elongate guide arms mounted orthogonally and in series so as to provide X, Y and Z axes for the guide. The arms are interconnected by carriage means allowing free relative movement between adjacent arms in at least one direction and a balancing means to allow substantially unbiased vertical movement for the arm or arms. The first arm is adapted for mounting to a reference point and the third arm is adapted for holding and guiding the tool.

Abstract: A guide for a machine tool including a vertical upper column (1) adapted for stable positioning at a work station and an elongate horizontally orientated arm (2) extending outwardly from and pivotally attached to the upper column at a pivot is disclosed wherein the pivot is provided by two vertically spaced apart pivot points (3) so as to allow the arm free radial movement in a horizontal plane.
