Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings, but does not constitute any limitation to the present invention. Similar component numbers in the accompanying drawings represent similar components. As mentioned above, the present invention provides a flexible adaptive underactuated robot gripper, which can be installed on the end of the small arm of an industrial robot to grab workpieces. The flexible adaptive underactuated robot gripper of the present invention relies on the small arm The movement of the robot claws to complete the action of grabbing the workpiece, the claws can automatically adapt to the size of the workpiece, the opening and closing of its fingers are flexible, and generate stable and uniform grasping force, while reducing the requirements for the control system.

[0021] In this embodiment, taking the grasping of a cylindrical workpiece as an example, the working process and principle of ...

Abstract

The invention relates to a robot paw, in particular relates to a flexible adaptive under-actuated robot paw. The flexible adaptive under-actuated robot paw comprises a framework, and a left finger and a right finger which are connected to the framework in a movable mode, wherein the left finger is positioned on the left side of the framework and provided with a left side hole; the right finger is positioned on the right side of the framework and provided with a right side hole; the framework is provided with through holes which are coaxial with the left side hole and the right side hole; four sliding shafts are arranged in the left side hole, the right side hole and the through holes; two pressure springs are arranged at two ends of each sliding shaft; and in two end faces of each pressure spring, one end face is pressed on each sliding shaft, and the other end face is pressed on the left finger or the right finger. The paw can automatically adapt to the size of a workpiece, the fingers are opened and closed flexibly, stable and uniform grasping force is generated, and the requirement on a control system is reduced.

Description

technical field [0001] The invention relates to a robot gripper, in particular to a flexible self-adaptive underactuated robot gripper. Background technique [0002] As one of the key components of the robot, the robot gripper is the last link and execution part of the interaction between the robot and the environment, and its performance determines the working performance of the whole robot to a large extent. [0003] The design of the mechanical part of industrial robots is an important part of industrial robot design. Although industrial robots are different from special equipment, they have strong flexibility, but it is unrealistic to design and manufacture universal robots. The differences in the mechanical system design of industrial robots in different application fields are much greater than the differences in other system designs of industrial robots. The hand of a robot used in industry is generally called an end effector, which is a part directly used by the robo...
