| 20140076157 | PISTON ASSEMBLY, FLUID PRESSURE CYLINDER, METHOD FOR MANUFACTURING PISTON ASSEMBLY - A piston main body ( | 03-20-2014 |
| 20140339753 | ELECTRIC CLAMP APPARATUS - An electric clamp apparatus includes a body, a rotary drive unit which is driven rotatably by an electric signal, a drive force transmission mechanism for transmitting a rotary drive force of the rotary drive unit to a toggle link mechanism, and a clamp arm disposed rotatably with respect to the body. By driving the rotary drive unit, a drive force is transmitted to the clamp arm through the drive force transmission mechanism, whereby the clamp arm is rotated through a predetermined angle with respect to the body, and a workpiece is clamped between the clamp arm and a support member of the body. At this time, an adjustment mechanism disposed on the clamp arm includes a rod, which advances and retracts so as to stably clamp workpieces of different plate thicknesses. | 11-20-2014 |
| 20140361478 | ELECTRIC CLAMP APPARATUS - An electric clamp apparatus includes a body, a rotary drive unit which is driven rotatably by an electric signal, and a rotary body rotated under a driving action of the rotary drive unit. Gear teeth of a clamp arm are enmeshed with helical screw grooves formed on the outer circumferential surface of the rotary body. The rotary body is rotated by driving the rotary drive unit, whereby the clamp arm, which is enmeshed with the screw grooves, is rotated through a predetermined angle to bring about a clamped state for clamping a workpiece. | 12-11-2014 |
| 20140367906 | ELECTRIC CLAMP APPARATUS - An electric clamp apparatus includes a body, a rotary drive unit which is driven rotatably by an electric signal, and a clamp arm disposed rotatably with respect to the body. By driving the rotary drive unit, a drive force is transmitted to the clamp arm through a drive force transmission mechanism, whereby the clamp arm is rotated via a link arm through a predetermined angle with respect to the body, and a workpiece is clamped between the clamp arm and a support member of the body. Further, rotational operation of the clamp arm is regulated by abutment of a sub-roller against an inclined portion of a displacement body. | 12-18-2014 |
| 20150145195 | CLAMP APPARATUS - A clamp apparatus is equipped with a body, and a drive unit having a piston displaced under the supply of a pressure fluid. A clamp arm is disposed rotatably on the body. In addition, a piston rod of the drive unit is connected detachably with respect to a displaceable body of a driving force transmission mechanism which is disposed in the interior of the body. Upon detachment of a connector of the piston rod from a connecting recess of the displaceable body, the state of connection between the drive unit and the driving force transmission mechanism is released. | 05-28-2015 |
| 20150343608 | CLAMP APPARATUS - A driving force transmission mechanism of a clamp apparatus includes first link arms, which are pivotally supported for rotation on ends of first and second piston rods, and second link arms, which connect other ends of the first link arms to respective ends on one end side of first and second clamp arms. Further, first rollers, which are provided on the one end of the first link arms, are guided in a horizontal direction along guide grooves of first guide members, and second rollers, which are provided on the other ends of the first link arms and the second link arms, are guided in a vertical direction along guide grooves of second guide members. | 12-03-2015 |
| 20150352691 | CLAMPING DEVICE - A clamping device has a pair of first and second clamping arms rotatably supported with respect to a body, and a cam member having a cam surface is removably provided at one end of each of the first and second clamping arms. A pair of rollers pivotally supported by a block body constituting a drive unit are each in contact with the cam member. By a descent of the block body under the driving action of the drive unit, the cam surface of the cam member is pressed by the rollers, and the cam surface inclined in the displacement direction of the block body and recessed in a cross-sectional arc shape is pressed. | 12-10-2015 |
| 20150352692 | CLAMP APPARATUS - A clamp apparatus is equipped with first and second clamp arms supported rotatably with respect to a body, and a drive unit having a pair of first and second pistons displaced under the supply of a pressure fluid. A driving force of the drive unit is transmitted to the first and second clamp arms through knuckle joints, which are connected to first and second piston rods, power-boost levers, and link arms. The power-boost levers are formed such that the length from a support pin toward the knuckle joint is longer than the length from the support pin toward the link arm. | 12-10-2015 |
