Grabbing mechanism and robot

Abstract

The invention provides a grabbing mechanism and a robot. The grabbing mechanism comprises a substrate; a plurality of connecting pieces arranged on the substrate, and at least part of the connecting pieces can move relative to the substrate; a plurality of grabbing pieces connected with the connecting pieces in a floating mode; a telescopic piece connected with the plurality of connecting pieces; and a driving piece connected with the telescopic piece and used for driving the telescopic piece to stretch out and draw back, and then at least part of the connecting pieces can be driven to move so as to adjust the distance between every two adjacent grabbing pieces. According to the grabbing mechanism provided by the invention, the distance between every two adjacent grabbing pieces can be adjusted, so that the applicability of the grabbing mechanism is improved, and the defect that the mechanism is frequently grabbed is avoided; and moreover, the grabbing pieces and the connecting pieces are in floating connection, errors within a certain range are effectively made up, and the machining efficiency of products is improved to a great extent.

Description

technical field [0001] The invention relates to the technical field of manufacturing and assembly, and in particular, to a grabbing mechanism and a robot. Background technique [0002] At present, in order to better adapt to the fast-paced and diversified market changes in today's market, it has gradually become a trend to produce different types of products. Taking the automobile industry as an example, different types of cars have different types of workpieces, such as engine cylinder blocks, cylinder heads, subframes, transmissions, clutches, steering knuckles, etc.; the production of different types of workpieces requires different casting molds. The workpieces formed in the lining can contain different types of specifications, and the workpieces of different types and specifications need different grippers to be grasped in the subsequent process. Therefore, whenever the mold is replaced, the grippers used in the subsequent process must be replaced accordingly, so multi...

AI Technical Summary

Problems solved by technology

Therefore, whenever the mold is replaced, the grippers used in the subsequent process must be replaced accordingly, so that multiple sets of grippers will cause additional costs, and the replacement of grippers will also bring additional man-hours, reducing the effective efficiency of the product

Moreover, frequent replacement of the gripper may lead to unstable installation of the gripper, and there is not enough space to place a variety of different types of grippers at the construction site

[0003] In response to the above technical problems, the composite grippers used in related technologies cannot solve the problem.

Because the sixth axis of the robot is used to install the gripper, the three-sided gripper substrate is the installation limit. When there are more than three types of workpieces, several different composite grippers are also required, and the problems that arise have not been resolved.
