  • Patent number: 9827642
    Abstract: In a clamping device, a detection mechanism detects a state of clamping/unclamping and includes: a detected body that moves together with a piston and a piston rod; a circuit board disposed to face the detected body and capable of detecting the position of the detected body; and an indicator lamp that is connected to the circuit board and is lit/extinguished depending on the state of clamping/unclamping. By pressing a setting button provided on the detection mechanism when the rotation angle of the arm is changed, the second detection position of the circuit board for detecting the unclamped state is changed, making it possible to detect the detected body at a newly set detection position.

  • Patent number: 8286955
    Abstract: The invention relates to a steady rest for clamping and/or for holding a workpiece (W) on a machine tool, comprising three holding members (3, 4, 5) mounted in a housing (2) and displaceable in a common plane, two of which are designed as two-armed levers pivotably supported in the housing (2), and the central holding member (5) is guided in a straight line. The two outer holding members (3, 4) are kinematically connected respectively to the central holding member (5) via an angle lever (10, 11) so that with an opening movement of the central holding member (5) the outer holding members (3, 4) are pivoted apart from one another. The angle levers (10, 11) are linked rotatably onto the central holding member (5), respectively the one leg of the angle levers (10, 11) being connected to the associated outer holding member (3, 4), and the other leg being connected to the housing (2) by means of gate/pin arrangements.

  • Patent number: 8256755
    Abstract: A clamp apparatus includes a clamp unit capable of retaining a workpiece, a cylinder driven under the supply of a pressure fluid, and a drive force transmission mechanism, which is capable of transmitting a drive force from the cylinder to the clamp unit. The drive force transmission mechanism includes a guide body disposed displaceably inside of a body, two pairs of rollers retained rotatably on both side surfaces of the guide body, and a spindle inserted through a second link groove of the guide body that rotatably supports a clamp arm. The clamp arm is rotatably operated and is capable of clamping the workpiece under a displacement action of the guide body.

  • Patent number: 8246029
    Abstract: A clamp device includes an annular grip member capable of being inserted into an hole in a workpiece and of gripping the inner circumferential surface of the hole, a clamp rod having a tapered shaft portion fitted inside the grip member and engaged therewith, a hydraulic cylinder capable of axially advancing and retracting the grip member and the clamp rod, and a clamp main body member. The clamp device is provided with seating surfaces formed upon the clamp main body member, on which the workpiece is seated, and a poor clamping detection mechanism that detects poor clamping, in the state in which the grip member is driven in its clamping direction by the hydraulic cylinder via the clamp rod, and the workpiece is in its state of being seated upon the seating surfaces.

  • 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: 8146900
    Abstract: A positioning and clamping apparatus, capable of positioning and clamping a panel material and removing the panel material from a locating pin under a state of releasing the clamping, is provided. A base having a contact surface contacting with the panel material is provided with the locating pin that penetrates through a through-hole of the panel material. A clamp arm moving between an escaping position and a clamping position is provided in a slit, and the clamp arm is moved between these positions by a reciprocating cam. When the clamp arm reaches the clamping position, the panel material is clamped by a clamp portion which is a tip of the clamp arm. A pusher driven by a pushing piston is provided inside the base, and the panel material is removed from the locating pin by the pusher.

  • 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.
