Automatic grabbing mechanical arm

Abstract

The invention provides an automatic grabbing mechanical arm. The automatic grabbing mechanical arm comprises a base, wherein a driving device is fixedly arranged at one end of the base, two or more sets of inner grabbing assemblies are hinged to the edge of the base, the driving end of the driving device is connected with a connecting shaft, a through hole matched with the connecting shaft is formed in the center of the base, the connecting shaft penetrates through the through hole and extends towards the inner grabbing assemblies, and a middle plate is arranged on the position, extending out of the through hole, of the connecting shaft; the inner grabbing assemblies are hinged to the middle plate through a movable connecting plate. When grabbing is carried out, the inner grabbing assemblies extend into products, then the inner grabbing assemblies are opened, the grabbing sections abut against the inner walls of the products, and certain preset force is achieved; the products are lifted and translated, so that the movement of the products is realized.; the bending parts of the bending sections are arc-shaped, so that the grabbing sections and the supporting sections are in contraction transition through the arc-shaped arrangement, and the grabbing sections and the supporting sections can extend into the products with smaller inner diameters and then expand outwards to realize the grabbing purpose.

Description

technical field [0001] The invention relates to the technical field of automatic production, in particular to an automatic grabbing manipulator. Background technique [0002] With the progress of the times and the development of science and technology, more and more enterprises have introduced automation equipment, which uses automation equipment, such as manipulators, to grab products and realize operations such as transferring, running or fixing products. [0003] The current manipulator grasps the product from the outside of the product, and performs operations such as transferring, running or fixing. However, some products need to be processed on the outer surface, or the outer surface is not suitable for grasping. For example, grasping is easy to cause damage and scratches on the outer surface, or the outer surface is easy to slip when grasping and the grasping is not firm. This prevents gripping of the outer sides. [0004] At present, although there is a method of g...
