A guide rail is provided on an outer surface of a chuck body. A pair of fingers is disposed on the guide rail. At least one of the pair of fingers is a movable finger that is movable along the guide rail. One or two cylinder apparatuses, each of which has a rod that advances and retracts in the direction of its axial line by the action of air pressure, are provided in the chuck body. The top end of the rod extends from an end of the chuck body to the outside. An end block is attached to the top end of the rod. The end block is linked to the movable finger.

The invention relates to a transport device (38) for transporting a workpiece (23) between a clamping chuck (22) and a workpiece carrier (30). The transport device (38) comprises a gripper arrangement (39) with a pivot arm (40). One end of the pivot arm (40) is supported on the machine tool (20) and, in particular, a machine slide (25) via a first pivot drive (41) so as to be pivotable about a first pivot axis (S1). On the other end, the pivot arm (40) supports a second pivot drive (42) that defines a second pivot axis (S2). A workpiece gripper (43) is supported so as to be pivotable about this second pivot axis (S2). The two pivot axes are inclined by 45 relative to each other. A workpiece (23) held by the workpiece gripper (43) has a workpiece longitudinal axis (W) that extends in a first position (I) of the workpiece gripper (43) at a right angle with respect to the pivot axis (S1). In a second position (II) of the workpiece gripper (43), the workpiece longitudinal axis (W) is oriented parallel to the first pivot axis (S1). The workpiece longitudinal axis (W) of the workpiece (23) held by the workpiece gripper (43) is inclined by 45 relative to the second pivot axis (S2).

A workpiece gripping device includes a base body and a pair of finger units configured to grip a workpiece. A first finger unit of the pair of finger units includes a scoop member configured to reciprocate in the direction of the arrow Z relative to the base body and rotate on a plane perpendicular to the direction of the arrow Z. A second finger unit of the pair of finger units includes a pressing member configured to reciprocate in the direction of the arrow X and rotate on a plane perpendicular to the direction of the arrow Z.

A piezoelectric drive device includes multiple piezoelectric drive units that have a contact portion which can come into contact with a driven portion, and that have a piezoelectric substance. The number of the multiple piezoelectric drive units is 10 or more, an overall output from the multiple piezoelectric drive units is 0.3 W or greater, and a weight of the piezoelectric drive unit is 1 g to 5 g.

A pneumatic gripper is provided which has a shell in which a pneumatic actuation group and an electronic command and control board are housed. The pneumatic actuation group has an internal body in which two pneumatic chambers are formed, a jaw actuation piston being slidably housed in each pneumatic chamber. The internal body houses cartridge solenoid valves suitable to control passage of air from an inlet port to the pneumatic chambers. A transducer shaft is operatively connected to the jaw actuation pistons so as to be actuated to rotate by a translation of the jaw actuation pistons.

Fingers for robotic grasping devices, robotic grasping devices equipped therewith, and associated methods. Such a finger includes a flexible beam mechanism having an axis extending through a proximal end and a distal end, and a slider movably mounted on the beam. Moving the slider along the axis of the flexible beam mechanism changes the stiffness of the finger.

Gripping device for crates having a first abutment and a second abutment in contact with two panels of a crate that are adjacent and perpendicular to one another. A first presser, in the active position, is able to press on the free edge of the first panel, exerting an operating thrust along at least the main direction, and a second presser, in the active position, is able to press on the free edge of the second panel, exerting an operating thrust along at least the main direction. A first cursor, in the operating position, is able to engage with the first panel, to prevent a movement of the first panel along the main direction, and a second cursor, in the operating position, is able to engage with the second panel, to prevent a movement of the second panel along the main direction.

A method and apparatus for dispensing and retrieving products is provided. A system may include: a grasping head; first and second grasping members, each grasping member comprising: a top member; a post member; and first and second grasping fingers, where the first and second grasping fingers extend from the post member and are spaced apart from the top member by a predetermined distance, where the first and second grasping members are connected to the grasping head, where at least one of the first and second grasping members is movably connected to the grasping head, where the at least one of the first and second grasping members is movable relative to the other of the first and second grasping members.

The present disclosure provides a robot gripper, comprising a bottom plate (101), a side plate A (102), an intermediate plate (103), a side plate B (104), guide rods (105), sliding blocks (106), cylinders (107), spherical joints (108), pneumatic quick plug connectors, a connecting plate (114), racks (115), a gear (116), a gear shaft (117), a horn type switch support (120), detection switches (121) and a detection head (122). By adopting the robot gripper, the bottom plate (101) can be connected with six-shaft flanges of a robot together by connectors; a gripper arm can be designed to connect the connecting plate (114) to grip a hub according to different demands; and the opening and closing state of the gripper can be detected by the detection switches (121). The robot gripper has the advantages of low price, compact overall structure, large clamping force, strong stability and the like.

A work head including a head main body, multiple movable bodies held to be approachable to or separatable from each other by the head main body, and an air passage formed, being open between the multiple movable bodies, in the head main body, in which by gripping a holding tool configured to hold a component by approach of the multiple movable bodies, the holding tool communicates with the air passage and holds the component by supply of air to the holding tool via the air passage.
