| 20100013137 | Clamping Device | 01-21-2010 |
| 20100187740 | PIPE GRIPPING APPARATUS - A pipe gripping apparatus has a first jaw with a pipe-contacting surface at one end thereof, a second jaw having a pipe-contacting surface at one end thereof, a tongue having a pipe-contacting surface at one end thereof, and an actuator connected to the first and second jaws and to the tongue. The actuator serves to move the first and second jaws and the tongue such that the pipe-contacting surfaces thereof move radially inwardly simultaneously for a substantially identical distance. A first link pivotally connects the tongue with the first jaw. A second link pivotally connects the tongue with the second jaw. The first and second links extend angularly outwardly from the tongue. The first and second pivot points of each jaw have a distance unequal to a distance between the first pivot point and pipe-contacting surface of each jaw. The pipe-contacting surfaces can be elastomeric pads, toothed dies, or rollers. | 07-29-2010 |
| 20130082428 | CLAMPING MECHANISM WITH CAMMED DRIVING LINKAGE - An exemplary clamping mechanism includes a mounting base, a clamping assembly and a driving assembly. The clamping assembly includes a rotating member rotatably assembled to the mounting base, drive pins, a guiding member, sliding members, and clamping members. The guiding member is mounted on the mounting base and defines guide slots. The sliding members are slidably engaged into the guide slots of the guiding member, and connected to the rotating member via the drive pins. The clamping members are assembled to distal ends of the sliding members, respectively. The driving assembly is mounted on the mounting base and connected to the rotating member thereby driving the rotating member to reciprocate to clamp or release a workpiece. | 04-04-2013 |
| 20130147104 | PENCIL SHARPENER - A pencil sharpener that has a strong clamping force, does not leave marks on the surface of the pencil due to clamping, and is easy to manufacture. The pencil sharpener includes a housing having a pencil insertion hole and a plurality of pivot parts arranged in a concentric circle around the pencil insertion hole, a frame body having a plurality of arc-shaped grooves, and a plurality of cam-shaped members that are pivotably attached to the pivot parts. When the frame body pivots, the cam-shaped members relatively move while being guided by the grooves, and their distal ends swing in a direction in which they move closer to or away from an insertion hole, and thereby a pencil that has been inserted is fixed or released. | 06-13-2013 |
| 20140265099 | AUXILIARY CLAMPING TOOL FOR WELDING OPERATION - An auxiliary clamping tool for welding operation includes a pair of pliers, and a resilient clamp set in between two jaws of the pliers for enabling hooks of the jaws to hook in respective hook holes of flat clamping arms of the inserted resilient clamp such that if the handle levers of the pliers are not squeezed, the jaws are closed and the retaining tips at the free ends of the flat clamping arms of the resilient clamp touch each other; if the handle levers of the pliers are squeezed, the jaws are opened and the retaining tips at the free ends of the flat clamping arms of the resilient clamp are kept apart from each other. | 09-18-2014 |
| 20140327201 | Self-Centering Clamp - A clamping device is configured to ensure that a workpiece fixed between the jaws of the clamp is self centered by coupling the jaws to a pair of linkages that rotate through the same angle as the application of a first causes the jaws to translate in linear fashion across the surface of the device. In particular, the clamping device utilizes coupled linkage (e.g., a 180° bell crank), in combination with slots for retaining opposing jaws and maintaining only linear movement of the jaws, thus providing a fast and accurate self-centering arrangement. The clamping device may also be located within a hollow workpiece and controlled to move the jaws outward and engage the inner surface of the hollow workpiece in a self-aligned configuration. | 11-06-2014 |
| 20140353898 | CLAMPING DEVICE, PARTICULARLY A CLAMPING MODULE - A clamping device includes a base part, a clamping element arranged such that it can be displaced relative to the base part in order to transmit a clamping force onto a part to be clamped, and a drive unit that displaceably impinges upon the clamping element. The drive unit has a threaded spindle or a threaded sleeve that can be driven rotationally by a motor to directly or indirectly cooperate with a corresponding part of the clamping element in such a manner that rotationally driving the threaded spindle or threaded sleeve effects a displacement of the clamping element and/or a generation of a clamping force. | 12-04-2014 |
| 20150054210 | CENTRIC CLAMPING VICE - A centric clamping vice for centric clamping of workpieces is provided that includes a base support having a longitudinal axis, on which a first jaw mount, guided by a first carriage, and a second jaw mount, guided by a second carriage, are adjustably supported along an adjustment path oriented parallel to the longitudinal axis with the aid of a spindle drive. A pair of first slides is assigned to the first carriage, and a pair of second slides is assigned to the second carriage, and the difference between the track width of the first slides and the track width of second slides is greater than the width of second slides. | 02-26-2015 |
| 269219000 | Spaced parallel screw means | 2 |
| 20140232053 | WORK BENCH INCLUDING A VISE - A work bench including a frame and a table surface connected to the frame. The table surface includes first and second table surface members. The first table surface member is movably coupled with the frame and has first and second ends. The work bench also includes a first user-actuatable drive member for moving the first end of the first table surface member, a second user-actuatable drive member for moving the second end of the first table surface member and a third user-actuatable drive member for moving the first end and the second end of the first table surface member concurrently. | 08-21-2014 |
| 269220000 | With specific means for angular positioning of jaws | 1 |
| 20080197555 | Positioning system for work piece milling - A clamping apparatus is disclosed for precision processing of a work piece on a wood shaper, a router table or a table saw. The clamping apparatus has a platform having a non-skid upper surface for holding a work piece and a low-friction lower surface. The platform has a work piece block to locate a work piece on the upper surface. At least one clamp holds the work piece in contact with the upper surface and the work piece block. The clamping apparatus also includes an overhead guide/guard that orients and holds the clamping apparatus in a desired configuration with respect to a fence. The operator moves the entire clamping assembly along a processing machine fence guide while engaging the overhead guide/guard continuously with the processing machine fence guide. | 08-21-2008 |
