20110018186 | POWDERED GRIP CLAMPING FORCE - A powered grip that can engage and hold an item which includes a primary body member, an actuator dependent from the primary body member and a pair of spaced apart clamp jaws to move towards and away from each other. A force transmission mechanism is operatively located intermediate of the actuator and each of the clamp jaws to displace the clamp jaws relative to the primary body and that, through mechanical advantage, establishes a multiplication of the force of the actuator force at the clamp jaws. A force transmission mechanism geometry adjuster is provided to vary the spacing between the clamp jaws for any given operating force applied by the actuator, allow the pre-testing setting of the spacing between the jaws such that the range of force applied by the clamping jaws to the item to be tested is within a desired range. | 01-27-2011 |

20120299234 | FIXING DEVICE - A fixing device for fixing a workpiece includes a base, a first pressing block pressing the workpiece to the base, a second pressing block, a first support member, a second support member, and a side pressing block. The workpiece includes a preprocessing portion to be machined, which has an inner surface and an outer surface, the inner and outer surfaces of the preprocessing portion are sandwiched between non-rigid materials during a machining process to avoid the generating of swarfs. | 11-29-2012 |
20130292893 | JIG FOR FIXING CYLINDER BLOCK - The present invention addresses the issue of providing a jig for fixing a cylinder block, said jig being capable of stably fixing a cylinder block and contributing to a reduction of the size of the whole equipment including a processing tool. A jig for fixing a cylinder block of the present invention is used for the purpose of fixing a cylinder block, and is provided with a table having the cylinder block placed thereon such that the crank cases of the cylinder block are positioned on the lower side, and a clamping device, which can project upward from the upper surface of the table, and which clamps a journal wall that separates the crank cases of the cylinder block from each other. | 11-07-2013 |
20140103594 | COUPLING FOR USE WITH A HOLDER - A coupling for use with a holder. A tool that can be attached to a holder using such a coupling. The coupling comprises a slot to hold the holder in a retaining position, a channel defining a pathway which permits movement of the holder from an outer peripheral edge of the coupling into the retaining position, and having a cam surface on its outer peripheral edge about which the coupling can be moved to facilitate movement of the holder out of the retaining position into alignment with the channel for removal. | 04-17-2014 |
20140239569 | UNIVERSAL CLAMPING FIXTURE TO MAINTAIN LAMINATE FLATNESS DURING CHIP JOIN - A clamping apparatus and method for maintaining a workpiece flatness during processing includes a base having a planar surface for receiving a first workpiece. Two sets of opposing clamping mechanisms are mounted to the base and include a clamp head at a distal end of a rod extending from a housing in removable overlapping relation to the first workpiece. Each set of the clamp heads are in opposing spaced relationship to each other defining a second workpiece area, and the clamp heads are configured to mate with a top surface of the first workpiece. A biasing member is coupled to each of the housings and apply a downward vertical force to the housings, rods, and the clamp heads for applying a downward vertical pressure to the first workpiece. The first workpiece is thereby discouraged from thermally expanding in a vertical direction and is thermally expandable horizontally along the planar surface. | 08-28-2014 |

20120043711 | FIVE AXIS MACHINE VISE - A five axis vise includes two separated vise body portions that are supported on a machine tool table or other support that fixes the vise body portions in position. The vise body portions have jaws spaced up from the machine tool table sufficiently to permit machining five surfaces of a work piece held in the jaws. A vise screw is rotatably mounted in one of the vise body portions, and extends to the other vise body portion to actuate a movable jaw on the other vise body portion. The vise screw is threaded into a jaw nut that has a drive surface that engages and drives a driven surface on the movable jaw, with the drive and driven surfaces being inclined relative to the axis of force application to provide a downward force component on the movable jaw as it is tightened. The vise screw is an assembly of a threaded shank or shaft and a hub that is rotatably mounted in one of the body portions, with the threaded shank or shaft being locked in position in the hub. | 02-23-2012 |
