Gripper structure and industrial robot gripper

Abstract

The invention discloses a gripper structure and an industrial robot gripper. The gripper structure includes a mounting seat and a gripping head assembly, the mounting seat includes two mounting parts arranged at intervals along the same first circumference, and the gripping head assembly includes at least two gripping heads , all the gripping heads are arranged at intervals along the same second circumference, the gripping head is provided with a connecting body and a gripping head body, one end of the connecting body is rotatably connected to the corresponding installation part, and the other end is fixed to one end of the gripping head body, so that the gripping head body The other end can expand away from the centerline of the second circumference or shrink close to the centerline of the second circumference. The outside of the gripper body is provided with first abutment parts and second abutment parts arranged at intervals along both ends of the gripper body. All the first abutting parts cooperate to form the first abutting structure, and all the second abutting parts cooperate to form the second abutting structure, so when in use, through the first abutting structure and the second abutting structure and the material The abutment of the inner hole wall realizes the purpose of multi-point abutment 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.
