Clamping device

Abstract

This application provides a gripping device, including a mounting base, a rotating assembly, and a clamping assembly. The rotating assembly is disposed on one side of the mounting base; the clamping assembly is disposed on the other side of the mounting base, connected to the rotating assembly and capable of rotating around a preset rotation axis under the drive of the rotating assembly. The clamping assembly includes a clamping driver, first and second clamps, with the clamping driver respectively drivingly connected to the first and second clamps to move the first clamp toward or away from the second clamp. The first clamp includes a first tip, and the second clamp includes a second tip, which cooperate to clamp materials. The gripping device of this application achieves adjustable clamping end posture through the rotating assembly, reducing reliance on significant compensation from external turntables or robotic wrists.
