Abstract

The invention discloses a clamping device and a driving method thereof. The clamping device comprises a basic shell, at least one clamping claw which can be driven, springs and a piston, wherein the piston is driven by the spring towards one direction; at least two springs are arranged on the outer surface of the piston; a bottom end cover is mounted at the bottom of the basic shell; a connectingrod is connected with the top center of the bottom end cover; at least one groove is formed in the outer surface of the clamping claw; and a first driving clamping claw surface and a second driving clamping claw surface are arranged on one side of the groove from top to bottom. The clamping device adopts the combined driving manner of a large-angle oblique plane and a small-angle oblique plane; when a fourth driving clamping claw surface with the large-angle oblique plane is adopted for driving, rapid separation of the clamping claw and a rivet is realized; and when a second driving clamping claw surface with the small-angle oblique plane is adopted for driving, the clamping claw can continuously apply clamping force to the rivet, so that the thickness and the boundary dimension of the clamping device are reduced.

Description

technical field [0001] The invention belongs to the technical field of clamping devices, and in particular relates to a clamping device and a driving method thereof. Background technique [0002] In mechanical processing, the positioning and locking of fixtures or workpieces and machine tools; the positioning and locking of molds and equipment; the robot quickly and accurately grasps or releases the items that need to be transferred; especially in mechanical processing, traditional fixture replacement requires screws and pressure plates , gaskets, etc. are locked, and then calibrate the plane reference and position reference processing, which is time-consuming and labor-intensive, and it is easy to cause product scrapping or damage to the tool machine due to human negligence. Using this fast locking method, the volume is small and the locking Strong force and high positioning accuracy. In the process of product processing, it can also be quickly removed from the machine too...
