A clamping device includes a first holder and a second holder. The first holder includes a first abutting member and a driving member. The driving member is coupled to the first abutting member. The second holder includes a second abutting member. The first abutting member and the second abutting member are oppositely disposed and spaced apart from each other to receive a workpiece. The driving member is coupled to the first abutting member to drive the first abutting member to move in a direction toward the second abutting member to clamp the workpiece between the first abutting member and the second abutting member.

The invention relates to a machining device, in particular for machining workpieces of wood, wood materials, plastic or the like, comprising a workpiece table with a workpiece holder for holding at least one workpiece, and a feeding device for supplying at least one workpiece to the workpiece table, wherein the workpiece can be positioned in three dimensions with respect to the workpiece table. The invention further relates to a corresponding method.

The present invention relates to a straight edge clamp that has a clamping head assembly and a stop assembly mounted upon the body of the straight edge. The head and stop are not connected together and the stop assembly is free to move with respect to the head assembly. The straight edge clamp body includes at least two sections that are hinged together to allow the sections to be folded upon one another when not in use and unfolded when in use.

A clamp apparatus including two pairs of first and second clamp arms, which are supported rotatably with respect to a body and are disposed mutually in parallel. First and second cam members including respective cam surfaces are provided on ends of the first and second clamp arms. The first cam members are pressed by rollers upon lowering of a block body under a driving action of a first cylinder that makes up a drive unit. The first clamp arms are rotated to assume a clamped state. The second cam members are pressed by rollers upon lowering of a block body under a driving action of a second cylinder of the drive unit, whereby the second clamp arms are rotated to assume a clamped state.

A vise having a modular construction that allows for ease of manufacture, assembly, and changeover or replacement of wear items, such as gripping surfaces of jaws of the vise. The modular construction also provides for reduced weight of the vise compared to conventional cast type vises. The vise also incorporates quick adjustment features allowing for the vise to be easily rotated, a position and size of an opening of the jaws to be rapidly adjusted, and a clamping force applied with ease.

A pipe clamp has a base with a fixed jaw and a beam extending from the base. A movable jaw member is slidably mounted on the beam. The movable jaw member includes a movable jaw disposed opposite the fixed jaw. A pivotable handle is mounted to the movable jaw member and a clamping mechanism is connected to the pivotable handle and operated by the pivotable handle to move the movable jaw relative to the fixed jaw. A latch secures the pivotable handle in any of a plurality of positions. A tripod stand may be provided for supporting the pipe clamp, the tripod having a multi-compartment storage spreader.

Systems and methods for a dual sided clamp. More specifically, a clamp with a channel configured to receive a level on a first side of the clamp, and a triangular shaped cutout configured to receive a shaft associated with different sized valves on a second side of the clamp.

Certain embodiments described herein are directed to devices which can be used to safely secure two or more workpieces to each other, e.g., to secure a cabinet face frame to a cabinet frame. In some examples, the device comprises a base configured to engage a first surface of the first workpiece and to receive an attachment device. The base can also be configured to engage a first surface of a second workpiece. The device may also comprise piston means configured to engage the second workpiece at a second surface. The device may comprise one or more plungers that can be used to actuate the attachment device to permit fastening of the workpieces once properly arranged. Methods of using the device are also described.

An embodiment device includes a clamp body having a clamp opening, an extension opening and a traverse block having an internally threaded portion, a reaction plate having a recess in a first face at a first side of the reaction plate and one or more pins disposed in the recess extending away from the first face, and further having an extension extending along a long axis of the reaction plate through the extension opening, and bearing blocks disposed on a second side of the reaction plate opposite the first side, where the traverse block is disposed between the bearing blocks. An actuator is aligned parallel to the long axis of the reaction plate and extending through each of the bearing blocks and through the traverse block, and the actuator has an eternally threaded portion engaged with the internally threaded portion of the clamp body.

A pressing tool performs a pressing operation for the press fitting of parts. One part can have different outer dimensions within a specified range. A tool part acts on the part, is a part of a pivoting jaw which has an action surface, and can be pivoted about a pivot axis from a starting position having a greatest opening width to a pressing position having a smaller opening width. A hydraulic piston movable in a hydraulic cylinder applies a piston force, depending on a hydraulic pressure in the hydraulic cylinder. A higher pressing force is in effect when a greater opening width of the pivoting jaw is provided and when the maximum piston force is reached. When any opening width that is smaller than the greater opening width is provided, a pressing force lower than the higher pressing force is in effect when the maximum piston force is reached.
