Problems solved by technology

However, the flexible mechanical grippers that have appeared in recent years are superior in terms of the degree of curvature of the gripper, the degree of fit with the target object, the stability and durability of the gripper, the maximum load capacity, the strength of the joint connection, and the development of underactuation. There are more or less deficiencies

Abstract

The invention discloses a flexible mechanical claw and a mechanical arm comprising the same. The mechanical claw comprises a palm and two or more fingers pinned to the palm, wherein each finger comprises an inner claw and an outer claw; each inner claw comprises integrally formed base plate and cross beams; two or more cross beams are located on the outer side surface of each base plate, and the tops of the cross beams and the end B of the base plate are separately provided with pin joints for being connected with the corresponding outer claw; each outer claw is a cambered surface plate whichis composed of two or more connecting plates and is bent to a set radian; and each connecting plate is separately pinned between two adjacent cross beams or between the end B of the corresponding baseplate and the adjacent cross beam of the base plate. The inner claws and the outer claws of the mechanical claw are made of flexible materials with different hardness, and the mechanical structure design of the inner claws and the outer claws is combined, so that the mechanical claw can well wrap a target object, and meanwhile, the mechanical claw has a very strong grabbing characteristic.

Description

technical field [0001] The invention belongs to the technical field of intelligent robots, and in particular relates to a flexible mechanical claw and a mechanical arm thereof. Background technique [0002] Mechanical claw, as the name implies, is a device that can replace human hands to perform a series of operations, mainly composed of hands and mechanisms for movement. To a certain extent, it can replace heavy labor by grabbing and carrying objects with a fixed program, and it can also be used in an environment that is harmful to the human body to protect personal safety. It is mainly used in machinery manufacturing, metallurgy, light industry, etc. Industrial sector. [0003] Most of the robotic claws at this stage have a single goal, generally only for one or two tasks. Again, the higher the flexibility of the gripper, the less damage it will cause to the target during work. Therefore, the traditional rigid mechanical gripper has limited its own application occasions...
