  • Patent number: 8235370
    Abstract: A clamp device includes a grip member, a clamp rod, and a hydraulic cylinder, and, by the grip member being inserted into an hole in a workpiece, it can grip the inner circumferential surface of the hole. The clamp device is provided with: a main body member; seating surfaces formed upon the main body member, upon which the workpiece is seated; a seating sensor that includes a pressurized air ejection hole opening to the seating surfaces; and a workpiece mounting surface that can receive and stop a workpiece at a position that is more advanced than the seating surfaces when the grip member is at an advanced position (its unclamped state), and that shifts together with the grip member during clamp operation when the grip member and the clamp rod shift towards retraction.

  • Patent number: 8215622
    Abstract: A clamp device including a detection mechanism provided to detect whether the clamp device is in a clamped state or an unclamped state. The detection mechanism includes a tilt plate tiltably placed inside a switch holder installed on a body and a sliding rod displaced together with a piston rod and displaced in the direction normal to the tilt plate. When the sliding rod presses and tilts the tilt plate while a piston is displaced, a second detection switch detects that the clamp device is in the unclamped state.

  • Patent number: 8132801
    Abstract: A positioning and clamping apparatus clamps a panel material by moving a clamp arm to a clamping position while the panel material positioned by a locating pin is supported by a workpiece supporting face of a workpiece support. An extruding member having a plurality of extruding rods protruding from the workpiece supporting face is slidably provided in the workpiece support, and the panel material is detached from the locating pin since the extruding member causes a tip face of the extruding rods to be moved to a carry-out position by the hollow piston. The extruding member is caused to protrude by a spring force up to a standby position located between the carrying-out position and the workpiece supporting position, thereby being pushed down up to the workpiece supporting position by the panel material.

  • Patent number: 8132800
    Abstract: A lock mechanism includes a casing that is fixed to a side surface of a body, a handle disposed rotatably on the outside of the casing, and a transmission section, which is capable of transmitting a drive force applied by the handle. An end of a guide rod making up the transmission section is connected in a body surrounding groove of a piston rod disposed inside the body. In addition, by rotating the handle, the guide rod of the transmission section is displaced vertically (upward and downward), such that an arm is rotationally displaced through a toggle link mechanism by displacement of the piston rod along the axial direction.

  • Patent number: 8028976
    Abstract: A new arrangement for machining parts is disclosed. The parts to be machined are mounted on fixture plates on a fixture. Using a stationary hydraulic line, hydraulic equipment is then pressurized by a pump within the fixture. The pump is mechanically powered by a separate (and disconnectable) power source. A rotatable coupling is attached to the pump. It receives a spindle from a CNC machine, enabling the machine to activate the pump by rotating the spindle while the spindle is received in the coupling. The coupling has axially extending prongs that form slots that accommodates the spindle. The prongs have ends that taper inwardly toward the slots. The spindle is also used to actuate a pressure release valve. The fixture also has at least four angled work faces and an access face that separates two of those faces. In operation, parts are first mounted on the fixture plates. The fixture is then moved to a work area, where the spindle actuates the pump, pressuring clamps that lock the parts in position.

  • Patent number: 7971916
    Abstract: A tool module associated with an end-effector for a robot arm that includes both linear and rotational locking mechanisms providing movement in five degrees of freedom. The tool module includes an integrated locking assembly that includes a linear locking mechanism and a rotary locking mechanism that are simultaneously locked and unlocked. The linear locking mechanism locks to a rod and the rotary locking mechanism locks and unlocks a shaft that is rigidly coupled to a swing arm. An opposite end of the swing arm includes another linear locking mechanism that locks and unlocks a shaft supporting a vacuum cup at an opposite end. The vacuum cup is mounted to a ball joint on the shaft that allows the vacuum cup to pivot. By locking and unlocking the locking mechanisms of the tool module, the end-effector can be readily configured to grasp and hold various parts of different dimensions and shapes.

  • Patent number: 7934710
    Abstract: In an embodiment, there is disclosed a clamp having a frame and a latch member mounted within the housing so that the latch member is translatable along a displacement axis and rotatable about the displacement axis. A cam follower mounted to the frame engages a channel operatively associated with the latch member. An actuator mounted to the frame and operatively associated with the latch member translates the latch member along the displacement axis. The engagement of the cam follower and channel causes the latch member to be rotated about the displacement axis as the latch member is translated along the displacement axis.
