Abstract

The invention discloses a flexible mechanical claw for a teaching mechanical arm, and belongs to the field of mechanical claws. A main body part comprises a fin-shaped flexible claw head, a claw head mounting base, a transverse moving module, a longitudinal moving module and a synchronous driving module. The fin-shaped flexible claw head is of a fin-shaped flexible structure, the whole mechanical claw can be driven by a motor to move in the transverse direction and the longitudinal direction, the functions of tightening and loosening of the mechanical claws in each group at the same time are achieved through a sliding gear, passive adaptive rotation is conducted through a torsion spring, and therefore self-adaptive grabbing of various types of objects can be achieved. According to the whole structure, the structural characteristics of the fin-shaped effect are fully exerted, and the flexible mechanical claw has the advantages of being high in adaptability, good in object enveloping effect, free of damage to grabbed objects and the like, and high in practicability.

Description

technical field [0001] The invention belongs to the field of mechanical claws, and in particular relates to a flexible mechanical claw used for teaching mechanical arms. Background technique [0002] Flexible mechanical claws have great potential for development, and a claw structure designed to simulate the "fin" effect has emerged. The mechanical structure is mainly composed of a slewing pair, a rigid support rod and a flexible surface. Due to the existence of the intermediate rigid connecting rod, this structure can withstand a larger load than other flexible structures. [0003] The fin-type structure has passive compliance, that is, it does not need an external drive to passively form an envelope based on its own structure after receiving an external force, and compared with the envelope effect of surface flexibility of sponges and air cushions, its The structural flexibility makes its envelope effect better. However, the structures of existing flexible grippers are u...
