  • Patent number: 11273556
    Abstract: The intelligent gripper for a hydraulic torque converter includes an upper supporting plate. A clamping mechanism, a vibration excitation mechanism and a drive rotating mechanism are arranged on the upper supporting plate. The clamping mechanism is used for automatically clamping a T-shaped cap of a hydraulic torque converter. The vibration excitation mechanism comprises a plurality of vibration excitation cylinders and a plurality of vibration excitation heads. The plurality of vibration excitation heads is driven to be alternately telescopic through alternate actions of the plurality of vibration excitation cylinders, to hit the hydraulic torque converter so as to achieve automatic and precise tooth alignment. The drive rotating mechanism includes at least two shifting blocks and at least two guide shafts.
