Abstract

The invention relates to the technical field of clamping devices, in particular to a rotary clamping device. The rotary clamp holder comprises a shell, a hollow cup motor, a hollow rotating shaft, a nested motor and a clamping jaw; the hollow cup motor and the nested motor are both fixed in the shell, the hollow rotating shaft and a rotor of the hollow cup motor are coaxially fixed, and the hollow rotating shaft is fixedly connected with a base of the clamping jaw; the nesting motor is located in the hollow rotating shaft, the hollow rotating shaft can rotate around the nesting motor, and a motor shaft of the nesting motor is connected and matched with the gripper of the clamping jaw and used for driving the gripper to loosen or clamp. According to the rotary clamping device, the clamping jaws can be subjected to rotary driving and clamping driving in a motor direct driving mode, the structure is compact, the size is small, the back clearance problem does not exist, and the rotary precision and the clamping precision are high; in addition, when the rotary clamping device works, a motor wire of the hollow cup motor and a motor wire of the nested motor cannot be wound in the shell, and the reliability is high.

Description

technical field [0001] The present invention relates to the technical field of grippers, in particular to a rotary gripper. Background technique [0002] A rotary gripper is a device that can grip and release an object and drive the gripped object to rotate. [0003] The existing rotary grippers generally use two motors arranged side by side to drive the grippers to rotate, clamp and release respectively through the action of gear sets or other mechanical transmission mechanisms. Not only is the structure poor, but the volume is relatively small Large, and there is a backlash at the mutual cooperation of different transmission parts of the mechanical transmission mechanism, which affects the rotation accuracy. [0004] To sum up, how to overcome the above-mentioned defects of the existing rotary clamper is a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0005] The object of the present invention is to provide a rotary cl...
