Mechanical grab

Abstract

The invention discloses a mechanical grab. The mechanical grab comprises a piston cylinder and a suspender body, a large through hole is formed in the center of the body, the piston cylinder is fixedly installed on the position over the large through hole of the suspender body, a piston rod of the piston cylinder is arranged in the through hole, an inverted cone is fixed to the piston rod of the piston cylinder, a guide rod is arranged in each straight through hole, guide grooves are formed in the guide rods, head portions of guide pins which are installed on the suspender body are arranged in the guide grooves in a lying mode, a movable arm is fixed to the outer end of each guide rod, and the movable arms are parallel to the center line of the piston cylinder; the lower ends of the movable arms are provided with inward claws; when the piston rod of the piston cylinder declines, the inverted cone drives the guide rods to move outwards, the opening between the claws is enlarged, workpiece grabbing is prepared, when the piston rod of the piston cylinder moves upwards, under the action of springs, the claws move inwards, and workpiece grabbing is achieved.

Description

technical field [0001] The invention relates to a mechanical gripper, belonging to the technical field of mechanical grippers. Background technique [0002] In the field of industrial automation technology and many production fields, manipulators can be said to be very common. Although the manipulators are not the same in structure, the separation or gathering movement of the ends of the jaws generally rotates around one or several fulcrums. Therefore, the contact between the jaws and the workpiece is generally point contact, so the grasping of the workpiece is not only not firm, but also due to uneven force, it is easy to damage the workpiece or the manipulator itself. It is easy to cause safety accidents if it is not taken firmly. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is: in view of the above-mentioned common defects existing in the existing mechanical gripper, the present invention provides a new type of mechanical gri...

[0002] In the field of industrial automation technology and many production fields, manipulators can be said to be very common. Although the structure of manipulators is different, the separation or gathering movement of the ends of the jaws generally revolves around one or several fulcrums. Therefore, the contact between the claw and the workpiece is generally point contact, so the grasping of the workpiece is not only not firm, but also due to uneven force, it is easy to damage the workpiece or the manipulator itself. In severe cases, even due to the grasping of the workpiece If it is not taken firmly, it is easy to cause a safety accident
