The clamping device allows for means to retain an electronic device or an electronic device in a case that is capable of fitting a wide range of differently sized and shaped electronic device. The self-centering mechanism and clamping device can also be integrated into the form of an adapter for various applications.

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.

A workpiece conveying apparatus for a pressing machine includes: a first arm supported so as to be rotatable within a substantially horizontal plane; a second arm supported on the first arm so as to be rotatable within the substantially horizontal plane; a workpiece holding device supported on a distal end side of the second arm so as to be rotatable within the substantially horizontal plane; a first arm drive mechanism configured to drive the first arm to rotate; a second arm drive mechanism configured to drive the second arm to rotate with respect to the first arm; a workpiece holding device rotation drive mechanism configured to drive the workpiece holding device to rotate with respect to the second arm; and a tilt drive mechanism configured to drive the workpiece holding device to rotate with respect to the second arm.

A transfer device is disclosed. The transfer device comprises a transfer rail extending in a longitudinal direction, a carrier movably coupled to the transfer rail in the longitudinal direction of the transfer rail, and a gripper assembly including a gripper module connected to the carrier. The gripper module includes a gripper frame extending in a width direction of the transfer rail and connected to the carrier, a cell mount coupled to an upper face of the gripper frame, and an alignment unit including an alignment body coupled to the gripper frame and an alignment arm movably coupled to the alignment body in at least one of a longitudinal direction or a width direction of the gripper frame.

A part-holding device includes a holding portion configured to hold an object to be held and a main body configured to detachably connected to the holding portion. The main body has a first surface, a second surface, and a third surface oriented in respective differing directions, and the holding portion has a first abutting surface, a second abutting surface and a third abutting surface capable of abutting against the first surface, the second surface, and the third surface, respectively. The part-holding device further includes pressing means configured to press the holding portion to cause the first abutting surface to abut against the first surface and to cause the second abutting surface to abut against the second surface, and fixing means configured to cause the third abutting surface to abut against the third surface and to fix the holding portion to the main body.

A machining center equipped with a device for mounting on a clamp parts to be worked or which have been worked, such as profiles, which has a supporting frame for supporting a turntable with two or more stepped positions or placements or workstations, an loading basket and an unloading basket. The machining center comprises a robot configured to remove or to associate, with each one of said two or more stepped positions or placements or workstations, the parts or the profiles to be worked and which have been worked at a plurality of fixed RPS or reference points and mobile mechanical components, according to a single positioning that is adapted to allow access by machining devices to any zone in the space of the profiles to be worked by modifying only the condition that the two or more stepped positions or placements or workstations are in.

The invention relates to an automation component or clamping device including a basic housing, at least one jaw movably guided in a jaw guide of the basic housing, and a piston movably guided in the basic housing, wherein the piston has a piston surface, wherein the piston is coupled in terms of movement to the jaw, and wherein a piston rod extending on the piston transversely with respect to the piston surface, wherein the centroid of the piston surface is spaced apart from the central longitudinal axis of the piston rod (22).

A dental milling machine has idle receptacles arranged in a storage chamber for storing a plurality of blanks. The blanks each are placed without frame as a frameless blank in the idle receptacles. A transfer device with a transport arm is arranged in the storage chamber. A work chamber adjoins the storage chamber. A transfer opening is arranged between work chamber and storage chamber. The transport arm grips a frameless blank stored in the storage chamber and moves it through the transfer opening into the work chamber. A workpiece holder arranged in the work chamber receives the frameless blank from the transport arm. The workpiece holder grips the frameless blank by a receiving rim of the frameless blank. The workpiece holder, for milling the frameless blank in the work chamber by a milling tool, holds by a clamping action the frameless blank at the receiving rim.

A wire electric discharge machine for machining a workpiece includes a handling device for handling core pieces produced by the machine during the machining of the workpiece and upper and lower wire guiding heads moveable with respect to each other and with respect to the workpiece. The handling device includes a gripper mounted in a fixed or movable relation to the upper wire guiding head. The gripper moves so as to face a produced core piece with its gripper base. The gripper includes a fluid inlet where fluid flow under positive pressure enters the gripper and a fluid outlet at the gripper base where the fluid flow exits the gripper. An interior of the gripper guides the fluid flow, producing a low pressure region at the gripper base as the fluid flow exits, generating lifting force to remove the produced core piece from the workpiece by movement of the gripper.
