Self-centering serialization rapid assembling clamp for rotary cabin type parts

The invention discloses a self-centering serialization rapid assembling clamp for rotary cabin type parts. The clamp comprises a clamp base, a center cone, sliding rods, rapid-changing soft claws, a resettable sliding table and a lifting mechanism, the center cone is of a conical structure, and the multiple sliding rods are evenly arranged at the periphery of the center cone along the radial direction at intervals; the inner end faces, making contact with the center cone, of the sliding rods are conical faces, the detachable rapid-changing soft claws are mounted at the outer ends of the sliding rods, and workpieces to be centered are arranged at the peripheries of the multiple rapid-changing soft claws; the bottoms of the sliding rods are mounted on the clamp base through the resettable sliding table, and the lifting mechanism is connected with the center cone. When the lifting mechanism controls the center cone to move downwards, the sliding rods are pushed to synchronously move outwards, the rapid-changing soft claws are driven to outwards abut against the inner wall of the workpiece, so that the rotation center of the workpiece is consistent with a machine tool. When the lifting mechanism controls the center cone to move upwards, the sliding rods are pushed to reset under the action of the resettable sliding table. The clamp improves the centering precision, and has the advantages of high precision and low cost.
