Pneumatic mechanical grabbing device

Abstract

The invention discloses a pneumatic mechanical grabbing device in the technical field of clamping devices. The pneumatic mechanical grabbing device comprises a shell. The top of the shell is providedwith a mounting groove. The front and rear sidewalls of the mounting groove are transversely and uniformly provided with right-angle sliding grooves. The middle of the top of the shell is provided with fixing clamping grooves. The middle of the bottom of the shell is provided with a limiting clamping groove. The middle of an inner cavity of the limiting clamping groove is provided with a limitinginsertion hole. Sliding blocks are mounted in an inner cavity of the mounting groove in bilateral symmetry. A cover plate is fixed to the tops of the fixing clamping grooves through screws. The coverplate is arranged on the tops of the two sliding blocks. According to the pneumatic mechanical grabbing device, the design that the right-angle sliding grooves and right-angle prisms can be engaged isadopted to prevent the interference phenomenon from existing in a wedge-shaped structure; moreover, the mutual fit tolerance is small, and the shaking phenomenon in the sliding process is avoided, sothat the pneumatic mechanical grabbing device conducts two-way grabbing more stably and is constant in grabbing force. The surface of the pneumatic mechanical grabbing device is subjected to hardening treatment. Thus, the pneumatic mechanical grabbing device has good wear resistance and impact resistance and can adapt to various hostile environments.

Description

technical field [0001] The invention relates to the technical field of clamping devices, in particular to a pneumatic mechanical grabbing device. Background technique [0002] A gripper is a device that holds an object to manipulate it. It is able to grip and loosen objects while performing certain actions. Motion equipment often mimics the movement of the human body, and in the case of grippers, the movement of fingers. The "fingers" themselves are not part of the gripper, they are just special custom tools used to hold the object, called "jaws". The most widely used gripper is the pneumatic gripper; it is essentially a cylinder powered by compressed air. When air is supplied, the gripper jaws will approach the object and hold it firmly for other manipulations, and when the direction of the air changes, the gripper will release the object. Typical applications are changing the orientation of an object or moving an object during a pick and place operation. When the clam...
