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

Abstract

The invention discloses a high-precision grabbing mechanism of a robot. The high-precision grabbing mechanism comprises a grabbing base which is of a circular structure, the grabbing base is provided with at least three sub-bases, and the sub-bases are arranged around the circle center of the grabbing base at equal interval and arranged in the axial direction of the grabbing base; each sub-base is provided with a clamping device and a driving device, each clamping device comprises a guide rail, each guide rail is fixed to the corresponding sub-base and provided with a sliding base, each sliding base is provided with a clamping base, a first clamping arm is hinged to each clamping base through a hinge, a second clamping arm is hinged to each first clamping arm through a hinge, and a third clamping arm is hinged to each second clamping arm through a hinge. According to the high-precision grabbing mechanism of the robot, the universality is high, the grabbing effect is good, not only is the grabbing capability on a workpiece with the flat surface high, but also the grabbing capability on a workpiece with the curved surface is high, and workpieces with different surfaces can be grabbed.

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...
