A device for transforming alternating rectilinear motion into intermittent rotary motion, in particular for the command of indexed rotary tables. The device includes at least one fixed base element (11) with cam guide elements (14), a moving slide element (12) associated with the fixed element, equipped with mechanical locator elements (15) following the cam guide elements (14) and susceptible to alternating movements on and with respect to the fixed base element commanded by an actuator, and an index plate (13) rotatably associated with the fixed element, interacting mechanically with the moving slide element (12) and susceptible to angular rotation pitch in answer to the alternating movements of the moving slide element. The index plate is connected to an indexed rotary table to be commanded.
摘要:
This invention concerns a pneumatically controlled grasping device to grasp and handle items or bodies provided with a graspable member. It comprises a supporting sleeve (16, 36) that internally delimits an intermediate space (23, 43) contiguous to a distal opening and a guide chamber (23′, 43′) connected to a source of fluid under pressure. In the intermediate space a gripper means (21, 41) is mounted, facing the distal opening and designed to engage with the graspable member. In the guide chamber a control piston (22, 42) is housed movable into a first position which corresponds to an activation or deactivation of the gripper means by the fluid under pressure, and to a second position which corresponds to the deactivation or activation of said gripper means, by at least a flexible reaction element (27, 47). The gripper means can be equipped to grasp the graspable member from the outside or from inside when it has a cavity.

The invention concerns a parallel pneumatic gripper which includes a gripper body (11) forming a chamber (15), an alternate pneumatic piston (12) movable in the chamber, and two jaws (13, 14) controlled by the piston and movable in opposite directions. A first jaw (13) is rigidly attached to the piston (12) to follow its movements, whereas the second jaw (14) is connected to the piston (12) by an oscillating transmission element or lever (22, 22′) comprising an intermediate larger dimensioned cross section portion (23, 30) having a transversal bore to house the oscillating central fulcrum and two terminal heads with rolling surfaces (25, 25′; 31, 31′) designed to couple with corresponding seats provided respectively on the bottom of a flaring shaped in one side of the piston (12) and in the second jaw (14).

摘要:
A fluid power gripper which contains a receiving space, in which two pistons are located able to be moved axially by fluid power in opposite drive directions, such pistons being kinematically coupled by a synchronization means. The synchronization means comprises first mesh means, which are provided on opposite mutually facing side surfaces of two mutually overlapping axial tails of the pistons. Furthermore the synchronization means comprises second mesh means provided on a body of revolution arranged between the two axial tails and having an axis of rotation extending athwart the longitudinal axis of the receiving space.
摘要:
A pneumatic parallel or radial gripper or air gun having two or more gripping jaws, wherein at least the gripping jaws their connection to the controlling piston are pre-assembled on a support that is made of plastic material. This allows for the subsequent assembly en bloc on the body in correlation with the piston. The support also acts as a device of protection.

The invention concerns a guide system with rolling elements, in particular ball bearings, for slide devices having a first and a second slide members (11, 12) coupled and guided between them, where a slide member (12) is susceptible to alternative linear movements compared with the other slide member (11) with the interposition of two linear sets of ball bearings (31, 31′). One of said slide members (12), on at least one of its sides parallel with the movement direction, has an opening which is integrated by a variable clamping finishing cheek (28) to establish an adjustable preload of the two sets of ball bearings between the first and the second slide members.
摘要:
The invention concerns a gripper device for gripping solid or hollow items, objects or bodies, which includes a supporting body (11, 11a) holding a plurality of gripper modules (12, 12a) positioned around the geometric axis of the body, parallel and spaced at an angle. Each module includes a flexible prehensible arch-shaped element (21, 21a) having an extrados in line with a radial slot (18, 18a) along one side of the housing and engaged by an actuator piston. All the prehensile elements are movable between a decontracted rest condition, in which their extradossis are retracted in the respective slots (18, 18a), and a compressed/contracted work condition, in which their extradossis protrude from the radial slots (18, 18a) to engage from time to time the item, object or casing to be gripped.
