Gripper structure and industrial robot gripper

Abstract

The invention discloses a gripper structure and an industrial robot gripper. The gripper structure comprises a mounting seat and a gripping head assembly, wherein the mounting seat comprises two mounting parts which are arranged at intervals along the same first circumference; the gripping head assembly comprises at least two gripping heads; all the gripping heads are arranged at intervals along the same second circumference; each gripping head is provided with a connector and a gripping head body; one end of each connector is rotatably connected with the corresponding mounting part while theother end of each connector and one end of the corresponding gripping head body are fixed, so that the other end of each gripping head body can be away from a center line of the second circumference to stretch or can be close to the center line of the second circumference to retract; the outer side of each gripping head body is provided with a first abutting part and a second abutting part which are arranged at intervals along the two ends of the gripping head body; all the first abutting parts are matched with one another to form a first abutting structure; all the second abutting parts are matched with one another to form a second abutting structure; and therefore, during use, the first abutting structure and the second abutting structure are abutted against an inner hole wall of a material so as to achieve the purpose of multi-point abutting against the inner hole wall of the material.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a gripper structure and an industrial robot gripper. Background technique [0002] With the continuous advancement of science and technology, the structure of mechanical grippers is widely used in assembly line operations. When the traditional mechanical gripper grabs materials, it often grabs the outer wall of the material. This kind of grabbing method is easy to pollute the material. The head supports the inner hole of the material to grasp the material. However, in actual production, the shape of the inner hole of the material is various and the size of the hole is different. It is difficult for the traditional pneumatic finger to make a Adaptive adjustment, so when supporting the inner hole of the material, the stability of the pneumatic finger support is poor, so it is necessary to equip corresponding grippers for different materials, which wastes resources.
