Mechanical gripper capable of conveniently adjusting grip force of clamping jaws

The invention relates to the technical field of mechanical grippers, in particular to a mechanical gripper capable of conveniently adjusting grip force of clamping jaws. The mechanical gripper capableof conveniently adjusting the grip force of the clamping jaws is characterized in that action of all groups of clamping jaw assemblies can be independently controlled, the clamping jaw assemblies caneffectively realize clamping for workpieces in different shapes, and meanwhile action of grip force control jaws is controlled by grip force drive control assemblies arranged in interval cavities, force limiting assemblies can limit the grip force of the grip force control jaws so as to enable the grip force to be not larger than limiting threshold force, and accordingly large clamping force canbe prevented well, and meanwhile the limiting threshold force is set in an adjustable mode, and then can be adjusted according to actual demands, and control ability of the mechanical gripper is improved.
