Abstract
This invention provides a lens clamping device, comprising: a base with a support assembly on it; a drive mechanism connected to and fixed to one side of the base with the support assembly; a transmission screw with its two ends rotatably connected to the base and the support assembly respectively, a threaded sleeve threadedly engaged with the transmission screw, the threaded sleeve slidingly engaging with the support assembly and only movable along the axial direction of the transmission screw; a torque transmission mechanism, the drive mechanism coaxially connected to the transmission screw via the torque transmission mechanism, and the torque transmission mechanism cannot transmit power after a set torque is exceeded; and a gripper disposed on the side of the base away from the drive mechanism and connected to the threaded sleeve via the transmission assembly. This invention ensures the stability of the gripper during clamping and effectively avoids over-clamping.
