Handheld spherical clamping device

Abstract

The handheld spherical clamping device comprises an operating rod and side clamping jaws, the side clamping jaws comprise at least two outer clamping jaws and at least two inner clamping jaws, a mounting base is arranged at the end of the operating rod, and the ends of the outer clamping jaws and the ends of the inner clamping jaws are hinged to the mounting base; the outer clamping jaws and the inner clamping jaws are alternately connected; a plurality of inner clamping grooves distributed circumferentially are formed in the inner surface of the outer clamping jaw, outer clamping grooves distributed transversely and circumferentially are formed in the outer surface of the inner clamping jaw, the inner clamping grooves and the outer clamping grooves are alternately connected, and the end clamping jaw can slide longitudinally and circumferentially along the side clamping jaw. When the side clamping jaws swing to a preset angle, all the end clamping jaws can form a closed spherical surface. The biggest difference is that the products are contained in the relatively closed cavity instead of being transported in a short distance through clamping force in the prior art, and due to the fact that the products are only subjected to the gravity effect in the clamping jaws, the products cannot deform or the surface quality cannot be damaged due to the clamping force.

Description

technical field [0001] The invention relates to the technical field of non-standard tools, in particular to a hand-held spherical clamping device. Background technique [0002] In the field of machinery, grippers are commonly used production tools and equipment. The clamping jaws in the prior art are mostly driven by pneumatics to open or close all the clamping jaws at the same time, while the existing clamping jaws use their own clamping force to fix the clamping target during the clamping process. An obvious disadvantage of the above clamping method is that when clamping a product with insufficient rigidity, it is easy to deform, which in turn affects its surface quality. For example, when the heated steel ball or glass ball is clamped by the existing three-hand gripper, in order to ensure the reliability of the clamping, the clamping force must be large enough, otherwise the clamping will not be firm. The higher clamping force is likely to leave marks on the product sur...

An obvious disadvantage of the above clamping method is that when clamping a product with insufficient rigidity, it is easy to deform it, which in turn affects its surface quality

For example, when the heated steel ball or glass ball is clamped by the existing three-handle jaws, in order to ensure the reliability of the clamping, the clamping force must be large enough, otherwise the clamping will not be firm. And the larger clamping force is likely to leave marks on the surface of the product
