A robot's high-precision grasping mechanism

Abstract

The invention discloses a high-precision grasping mechanism of a robot, which includes a grasping base, the grasping base is a circular structure, and at least three sub-bases are arranged on the grasping base, and the The sub-bases are arranged at equal intervals around the center of the grabbing base, and the sub-bases are arranged along the axial direction of the grabbing base. The sub-bases are provided with a clamping device and a driving device. The clamping device It includes a guide rail, the guide rail is fixed on the sub-base, and the guide rail is provided with a sliding seat, the slide seat is provided with a clamping seat, and the clamping seat is hinged with a first clamping arm through a hinge, The first clamping arm is hinged to a second clamping arm, and the second clamping arm is hinged to a third clamping arm, which has strong versatility and good gripping effect, and can grasp workpieces with flat surfaces. It has a strong grasping ability, and has a strong grasping ability for workpieces with curved surfaces, and can grasp workpieces with different surfaces.

Description

technical field [0001] The invention relates to the field of robot manufacturing, in particular to a high-precision grabbing mechanism for a robot. Background technique [0002] With the continuous development of science and technology and the decline of the demographic dividend, labor costs are getting higher and higher. In order to save costs and improve production efficiency, more and more companies are transforming their production and starting automation equipment to replace existing manual operations; automation Operation can not only reduce labor costs, improve production efficiency, improve product quality, but also facilitate production management. [0003] In automated production, robots and manipulators are frequently used, and the Chinese invention patent application number 201320323572.4 discloses a grabbing mechanism, including a bracket, a servo motor, a ball screw and a jaw assembly; the servo motor is fixed on the bracket Above; the servo motor drives the s...

AI Technical Summary

Problems solved by technology

[0004] Although this solution can realize the clamping or loosening of the object, it can clamp the workpiece well, and the positioning is accurate, and it can grasp the workpiece with a regular surface, especially for the workpiece with a symmetrical surface and a flat surface. Workpieces, such as cuboid workpieces, have better gripping ability, but their gripping ability to workpieces with curved surfaces is poor, and the gripping ability to workpieces with different surfaces is poor, and the versatility is not strong
