Parallel pneumatic gripper with body and jaws obtained from extruded elements

A pneumatic gripper comprising:

• a body formed by an extruded element and finished by extrusion, said body defining a longitudinal cavity delimiting a first cylindrical seat and a second prism-shaped seat, which are substantially parallel and open towards one another;
• said second seat having longitudinal guide faces on at least two opposite sides;
• two jaws linearly movable in opposite directions in said body for closing and opening on a piece to be gripped and to be released, said jaws being formed by pieces of extruded elements which are finished by extrusion and are shaped substantially complementary to said second seat;
• a pneumatic piston in said first seat;
• connecting means for transmitting movement from said piston to said jaws;
• two heads inserted in and fixed to opposite ends of said body, said pneumatic piston being accommodated in and being moved in a chamber defined by said two heads, said first seat being closed at its ends by said inserted two heads, each of said two heads defining a hole on an axis of said second seat.

• two heads inserted in and fixed to opposite ends of said body, said pneumatic piston being accommodated in and being moved in a chamber defined by said two heads, said heads having a cylindrical portion, which extends like a cover in said first cylindrical seat of said body, and in which said cylindrical portions of said two heads together delimit said chamber for accommodating and guiding said piston for controlling said jaws.

A pneumatic gripper comprising:

• a body formed by an extruded element and finished by extrusion, said body including two lateral walls;
• two jaws linearly movable in opposite directions in said body for closing and opening on a piece to be gripped and to be released, said jaws being formed by pieces of extruded elements which are finished by extrusion and are shaped with said body in a complementary manner;
• a pneumatic piston for controlling the movement of said jaws;
• connecting means for transmitting movement from said piston to said jaws;
• two heads inserted in and fixed to opposite ends of said body, said pneumatic piston being accommodated in and being moved in a chamber defined by said two heads;
• an adjusting screw arranged in said lateral walls in order to adjust a joining clearance between said body and one of said jaws and said piston.
