摘要:
This invention relates to a pneumatically controlled finger gripper that has a supporting body (111) forming a chamber. A fixed axial rod (119) is secured to a proximal part of the body, extending in the chamber and emerging from a distal part of the body. A compression disk (113) is connected to the fixed rod. A pneumatic control piston (112) is guided along the axial rod and moves in the chamber (115) with respect to the compression disk (113) between an inactive position, at a distance from the compression disk, and a forward active position, near the compression disk. A flexible gripper element (114) is mounted between the compression disk (113) and control piston (112). The flexible gripper element moves between a contracted position and an expanded position in response to the movements ofthe control piston between the inactive and active positions of the compression disk.
摘要:
The invention concerns an angular pneumatic gripper structure having a body (11) formed of two symmetric and identical elements or shells (15) realised and finished individually using a forming process and then associated and attached face to face to form together a housing chamber of an alternating piston (12) and means for receiving and guiding an intermediate drive (13) transversely and some grips (14) so as to turn driven by the piston through the drive. The elements or shells forming the body are made using die-casting, sintering or forging processes with material suitable for these forming techniques.
摘要:
A linear operators or axes is disclosed which comprises a fixed linear body, a body guided and movable alternately on the fixed one with interposition of bearings, and at least one pneumatic or electric actuator to control the alternating movements of the moving body on the fixed body. The fixed and movable bodies (11, 12), are made up of extruded profiled elements, they are of the same width and along each of the longitudinal opposite sides of each of them a profiled groove (22, 23) is provided so that the collateral grooves of the two joined bodies are the same, parallel, positioned on the same plane and made to receive the fixing brackets for at least one control actuator.

A recirculating linear ball bearing is disclosed which comprises a central metal body (11) and two facing shells (12) of synthetic material, enclosing the central body, and forming with the latter and endless race for recirculating of a number of balls (13); the two shell are fixed together by two screws (13), positioned in parallel and facing in the same direction from opposite sides of the central body.
摘要:
A pneumatic linear actuator has a body (10), a chamber (14) in the body that is closed by the end heads (15), a piston (11) that is arranged in the chamber and moved by a fluid sent alternately to the ends of the piston, and a slide or carriage (13) that is movable on the body driven by the piston. A belt (20) is driven on pulleys (19, 21, 22) and connects the piston to the slide, so that a stroke and a velocity at least twice that of the slide correspond to the stroke of the piston.
摘要:
A parallel pneumatic gripper is provided with body (11) and jaws (13), which are pieces of extruded elements made of aluminum or its alloys, finished by means of extrusion and designed to be joined in a complementary manner. In addition, this pneumatic gripper has a control piston (14) that accommodates and is moved in a chamber (25) defined by two heads (12) inserted and fixed to the opposite ends of the body.
摘要:
A fluid operated gripper which possesses a gripper device housing resembling a hollow body and on which a bearing body is secured. On the bearing body at least two relatively moving gripper device jaw carriers are movably mounted in a slot arrangement. A drive piston runs in a piston chamber. The bearing body is designed in the form of an insert body, which is seated like a cartridge in a receiving chamber arranged in an axial extension of the piston chamber. The slot arrangement is overlapped to the side externally by the housing wall, which delimits the receiving chamber, for at least part of its length.
