A device for supporting and/or guiding a machine tool or a workpiece, wherein the device includes a contact body having a contact surface for contact on a work surface of a workpiece or a wall. It is provided that the contact body includes a holding element having an adhesive means for adhesion to the work surface, wherein the adhesive means, when the contact surface of the contact body bears against the work surface, can be brought from a positioning state, in which the adhesive means is not in contact with the work surface and the contact surface can be positioned with respect to the work surface into an adhesive state, in which the adhesive means adheres to the work surface and fixes the contact body on the work surface.

A portable rail system for mounting an engraving device includes rails and crossbar members that are precisely joined, and include height adjustment devices for incrementally adjusting the height of the rail system relative to a work surface or contact surface, thus making the portable rail system capable of being assembled and disassembled at a work site to enable the use of an engraving device, such as a CNC router engraving systems, in situ, or on-site, rather than in a workshop. The portable rail system enables the use of a CNC router device or other engraving device on vertical surfaces.

This invention provides a guide for use with cutting power tools such as routers, circular saws, rotary cutters and the like. The invention provides a secure path along which a power tool can be used. The invention provides a device that is securely held against a surface by either user pressure or suction pressure and maintains its position along the surface to be cut. The invention can be configured to provide for varying cutting tools and differing attachments that are on the cutting tool and would be slid along the invention to effectuate a cut.

A straight edge guide system is presented that makes clamping of a workpiece faster and easier. The straight edge guide system includes a guide member that extends a length from a first end to a second end. A clamp member is connected to the first end of the guide member and includes a compressible bias member therein. An adjustable stop member is connected to the guide member that moves between a locked position and a free position. When the adjustable stop member is in the free position, the adjustable stop member slides along the length of the guide member. When the straight edge guide system is placed on top of a workpiece, the workpiece is clamped under spring bias force between the clamp member and the stop member.

A rail shoe assembly for mounting a drilling machine to a rail of a railway track, with the drilling machine including a drill, a cutter, and a support frame with the support frame mounted to the rail, includes a base adapted to be positioned with respect to the rail and adapted to be coupled to the support frame. The rail shoe assembly also includes an adjustable bar coupled to and slideable relative to the base. The adjustable bar has a bottom edge for engagement with the rail. The adjustable bar defines a plurality of position indicators and the base defines a plurality of mounting chambers. At least one of the plurality of position indicators and at least one of the plurality of mounting chambers are alignable at a predetermined position for positioning said base relative to the rail such that the drill and cutter are positioned relative to the rail.

A tool assembly is provided with an integrated support fixture and assemblies for orienting the tool at different angles relative to a workpiece. A guide rail assembly is provided that defines a travel path for the tool slidably supported thereon. The support fixture is configured to support the tool assembly on a workpiece so that gravity can assist movement of the tool across the workpiece. The guide rail assembly is mounted on a miter plate that can be oriented at different miter angles relative to the support fixture. The tool may be supported on the guide rail assembly to permit pivoting of the tool perpendicular to the miter angle. Another assembly may be provided that permits pivoting of the guided rail assembly at an orthogonal angle.

A movable seat and a rail device. The movable seat includes a main body; an air passage, an air sucking passage and an air intake passage formed in the main body; a sucker disposed under bottom face of the main body and an operation/control member mounted on the main body. When the operation/control member is positioned in a locking position, the air passage or the air intake passage keeps in a communication state and make the sucker a sucking force. When the operation/control member is positioned in a releasing position, the air passage or the air intake passage is blocked. By means of easy operation, the movable seat can create sucking force and locate or stop providing sucking force. One or more movable seats can be connected with multiple beams to form the rail device, which can be quickly located or moved.

Embodiments of the present disclosure include portable milling tools and methods for milling components. In an embodiment, a portable milling tool can be provided for a component including a plurality of dovetail slots therein, each of the plurality of dovetail slots being oriented substantially axially relative to a rotation axis of the component. The portable milling tool can include: a mounting plate configured to engage the component; a tool-aligning member slidably coupled to the mounting plate and extending along a chordal axis relative to the rotation axis of the component; and a milling head extending axially from the tool-aligning member to a selected one of the plurality of dovetail slots, such that sliding movement of the tool-aligning member relative to the mounting plate moves the milling head along the chordal axis to contact a selected one of the plurality of dovetail slots.

Tools and methods are provided for scarfing rotor blade segments. A rotor blade segment includes a pressure side and a suction side. A tool includes a first guide configured for mounting on one of the pressure side or the suction side, the first guide including a first curved rail and a second curved rail spaced from the first curved rail. The tool further includes a second guide movably coupled to the first guide at a scarf angle, the second guide including a guide rail extending between and movable along the first curved rail and the second curved rail. The tool further includes a cutting device movably coupled to the second guide, the cutting device movable along the guide rail and operable to remove material from the one of the pressure side or the suction side.

An apparatus for supporting a tool in an assembled apparatus. The apparatus includes a support structure, the support structure having a central member and a plurality of support members pivotally mounted on the central member. The support members are movable between a non-deployed position in which the support members extend a minimum distance from the central member and a deployed position in which the support members extend a maximum distance from the central member.
