A straight edge clamping device for clamping workpieces includes an elongated hollow base, and first and second stops. The first stop is fixed at the base, and the second stop is movably provided along the base. The second stop has a body movably received in the channel of the base and a slider that slides in the channel and along the lower wall of the base, contacts the workpiece, and engages with the body in a locking state and disengages from the body in a releasing state. The body has a sliding portion and pressing bumps, and the slider has pressing portions having outer surfaces and inner surfaces. In the locking state the pressing bumps contact with and push the inner surfaces of the pressing portions outwards, so that the outer surfaces of the pair of pressing portions are pushed outwards and contact sidewalls of the recess tightly.

Device for machining an end of an elementary panel for its subsequent friction stir welding, the elementary panel comprising a metal body defining two opposite faces, the machining device comprising a chassis, at least two guiding members configured to guide a first face of the elementary panel, at least one machining tool mounted on the chassis, the machining tool being positioned between the two guiding members and at least one pressure member mounted on the chassis and configured to exert a pressure on a second face of the elementary panel so as to press the elementary panel against the guiding members along the horizontal reference direction.

A carpentry featherboard having a curved contact surface generally configured in the shape of a spiral and having a pivot point of the body and a plurality of radii defined between the pivot point and portions of the contact surface, the radii progressively increasing in dimension to define the spiral shape of the featherboard body.

An anti-kickback device is disclosed where the device includes a plurality of flexible members, and at least a compliant contact surface in contact with a moving workpiece, where the flexible members provide a biasing force against the workpiece and also resist or prevent kickback of the workpiece as it engages a tool such as a shaper, saw blade, etc. The configuration of the flexible members assures an opposing force to resist kickback.

A power carpentry feeder machine includes a power source; a rotary wheel operatively coupled to the power source; horizontal guide rods horizontally coupled to the power source; a horizontal movement unit including two movable blocks having horizontal guide holes to receive the horizontal guide rods therein, locking members attached to the movable blocks, a connection block interposed between the two movable blocks and including vertical guide holes, and jointing members jointing the movable blocks to the connection block; a mounting base including a base board and vertical guide rods vertically coupled to the base board and extending through the vertical guide holes; and a vertical movement unit including springs encompassing the vertical guide rods to set the connection block under the springs and a clamp block having clamping holes to receive the vertical guide rods to extend therethrough so as to set the clamp block on the springs.

A manufacturing includes a template support and a plurality of template members. The template support comprises a structural member, a first rail, and a second rail. The first rail is coupled to the structural member, and is positioned outward of the first side of the structural member and extends parallel with the structural member. The second rail is movably coupled to the structural member and is normally biased outward to an outward position in which second rail is parallel with the structural member. Each template member is coupled to the template support when the first rail is positioned in a first recess thereof and the second rail is in the outward position in a second recess thereof, and is removable from the template support when the second rail is in an inward position and out of the second recess.

An automatic milling machine mills a gasket. The automatic milling machine controls the position of a cutter head relative a table. The automatic milling machine rotates the gasket with a motor. Parameters of the motor are monitored to determine the amount of rotation of the gasket.

An adjustable device for cutting an object has a frame with a back member that extends between a pair of feet. The feet are adjustably connected to a work bench or portable work table assembly. A spring biasing member has a back plate and a pair of side rods that extend from the back plate, through the back member, and are connected to a front member. A plurality of spacers are positioned between the front and back members.

An anti-kickback device is disclosed where the device includes a plurality of flexible members, and at least a compliant contact surface in contact with a moving workpiece, where the flexible members provide a biasing force against the workpiece and also resist or prevent kickback of the workpiece as it engages a tool such as a shaper, saw blade, etc. The configuration of the flexible members assures an opposing force to resist kickback.

The present invention discloses a multifunctional end effector, comprising a base (54) and a cutting tool (39); a feed slide (52) on the base (54) and a feed driving mechanism used to drive feed slide (52) to feed cutting tool (39); a swing slide (55) on the feed slide (52) and a swing driving mechanism used to drive swing slide (55) to realize circular arc swing of cutting tool (39); a mounting base (12) on the swing slider (55); a revolving rotation shaft (20) and a rotation shaft driving mechanism used to drive revolving rotation shaft (20) to make the cutting tool rotate in the mounting base (12); an eccentric slide (27) fixed to the end of revolving rotation shaft (20); cutting tool (39) is connected to the end of eccentric slide (27) via the electric spindle (37) and an eccentric regulating mechanism used to regulate eccentric slide (27) and control radial bias of cutting tool (39). Use feed driving mechanism to realize feed of cutting tool or feed of cutting tool along the swing trail through combination with swing driving mechanism; use eccentric regulating mechanism to realize radial bias of cutting tool; make use of rotation shaft driving mechanism to realize feed of cutting tool along the helical trail; it can realize such functions as drilling, boring, reaming, helical milling and reaming of elliptical recess.
