This disclosure describes systems, methods, and devices for accurately locating the center mark for a center punch on a metal strut, which is commonly used to support cable trays and pipes in various industries. The device solves the problem of inaccurate center marking by using a center punch and a punch alignment guide. The guide sets the punch in a precise position, and by placing the device on the strut and pressing a button, a small indentation is made on the metal to mark the center point accurately. This ensures that drilling or cutting tools do not slip or wander and that holes or cuts are placed accurately.

An air bearing slide (20) arranged on a rotational table (11) includes a movable table (40) that has a workpiece placement surface (42a) and that floats due to pressure of compression air to be movable horizontally in any direction. A workpiece auto-centering apparatus includes: a plurality of stopper apparatuses (30) that include an abutment portion (31a) against which a workpiece W can abut to center the workpiece W, and a pressing apparatus that presses the workpiece (W) such that the workpiece (W) abuts against the abutment portion (31a) of the stopper apparatuses (30). Thus, the workpiece auto-centering apparatus and auto-centering method have a simple configuration and can perform a workpiece centering operation in short cycle time.

A base assembly for a power tool, such as a router, includes a base member, an adjustment mechanism, and a lock member. The base member is configured to accept a motor housing of the power tool. The adjustment mechanism is configured to adjust a position of the motor housing relative to the base member via rotation of a first contact portion of the adjustment mechanism. The lock member is moveable relative to the adjustment mechanism between a first position that prevents rotation of the adjustment mechanism and a second position that permits rotation of the adjustment mechanism. The lock member includes a second contact portion positioned proximate to the first contact portion and configured to be actuated to position the lock member in the second position. The position of the motor housing is adjusted by simultaneously actuating the first contact portion and the second contact portion.

A barrel cam device includes a barrel cam, an output table that includes a plurality of cam followers that engage with the barrel cam, and that rotates by rotation of the barrel cam, and a clamp device that clamps the output table when the output table is stopping.

This invention is directed toward a panel framing device. The device comprises a portable framing table that can be driven in a trailer to remote locations and a pre-printed roll of framing tape that is used to tell a worker where different parts of a framed panel will go. The goal of the device is to facilitate the building of structures using a panel approach, with the framing table and template tape minimizing the chances that a worker will make a mistake in either the selection of materials or the location of the materials. The technology can also be used to construct entire walls, which are then either transported to the site, or merely tilted-up into place, having been constructed on the slab.

A working height adjustment device of a processing machine includes a retaining frame, a slide seat, and a lever having a connecting rod pivoted between the retaining frame and the slide seat. An adjustment seat of the slide seat has an accommodation hole. The accommodation hole is provided with an elastic member, a movable member, and an eccentric rod. The movable member has an engaging hole. The engaging hole has a diameter greater than that of a micro adjustment screw rod. The engaging hole has a toothed portion. Thereby, the eccentric rod is turned to push or release the movable member for the toothed portion of the engaging hole to engage with or disengage from a threaded section of the micro adjustment screw rod, such that the micro adjustment screw rod is tuned or the lever is pulled up and down to adjust the cutter seat quickly.

The present invention is a positioning work stop for use with a with a machining apparatus for performing a machining operation on a work piece, the positioning work stop comprising a retractable element having an extended position for contacting a work piece to ensure that the work piece is in its proper position for machining and a retracted position that provides a gap between the positioning work stop and the work piece, a biasing element that exerts a rearward biasing force of the retractable element, and a stop pin, wherein during the machining operation, when the machining apparatus contacts the stop pin the rearward biasing force automatically moves the retractable element into its retracted position creating a gap between the positioning work stop and the work piece.

A side stop device used to locate and relocate the left to right, or X direction, position of work material held by a machine vise is disclosed. The side stop device comprises an X direction shaft which fastens the side stop device to the vise, a rear block, a front block, and a Y direction shaft. The X direction shaft and Y direction shaft are fastened to the rear block. The Y direction shaft is fastened to the front block which clamps a small X shaft. The position of the small X shaft is used to locate the work material in the X direction.

A woodworking jig to hold lumber may include a central column; a chainsaw support assembly to slidably connected to the central column; an angle grinder support assembly to slidably connect to the central column; and a vertical log support to support the lumber positioned alongside of the central column.

A spindle phase indexing device for a machine tool is equipped with a guide rail detachably or fixedly attached to a table, a phase indexing jig configured to travel on the guide rail and which includes a first fitting part, a cutting tool including a second fitting part configured to be fitted with the first fitting part, and a controller configured to store therein a phase of a spindle at a point in time when the first fitting part and the second fitting part are fitted together. The first fitting part and the second fitting part are formed such that rotation of the cutting tool is constrained when the first fitting part and the second fitting part are fitted together.
