Mechanical arm with adjustable length

Abstract

The invention discloses a mechanical arm with the adjustable length. The mechanical arm comprises a first shell. A sliding groove is formed in the inner wall of the first shell. A connecting rod is movably connected in the sliding groove in a clamped manner. A through hole is formed in the surface of one end of the first shell. One end of the connecting rod penetrates the through hole in the surface of one end of the first shell, and a fixed plate is welded to the center axis of the surface of the other end of the connecting rod. Sliding grooves are formed in the surfaces of the two sides of the first shell. A sliding block is movably connected in each sliding groove in a clamped manner. The surface of one side of each sliding block is connected with a rotating rod through a rotary shaft,and the other end of each rotating rod is connected with a gripper through a rotary shaft. A first guide rod is welded to the center axis of the surface of one end of the connecting rod. Through the mechanical arm, the length of the mechanical arm can be easily changed by operation personnel, convenience and labor saving are achieved, and the work efficiency is improved; and the grabbing range ofthe grippers can be adjusted, the physical power labor intensity of labor personnel can be reduced, the operating cost of companies can be reduced, and the company profits can be improved.

Description

technical field [0001] The invention relates to the technical field of an industrial mechanical arm, in particular to an adjustable length mechanical arm. Background technique [0002] The robotic arm refers to a high-precision, high-speed dispensing robotic arm. The robotic arm is a complex system with multiple inputs and multiple outputs, highly nonlinear, and strong coupling. Because of its unique operational flexibility, it has been widely used in industrial assembly, safety and explosion-proof fields. [0003] The manipulator is a complex system with uncertainties such as parameter perturbation, external interference and unmodeled dynamics. Therefore, there are uncertainties in the modeling model of the manipulator. For different tasks, it is necessary to plan the motion trajectory of the joint space of the manipulator, so as to cascade to form the end pose. [0004] However, the existing mechanical arms cannot adjust the length. If different mechanical arms are requi...

Problems solved by technology

[0004] However, the existing mechanical arms cannot adjust the length. If different mechanical arms are required to work, the mechanical arms of different lengths must be replaced continuously. In addition, the existing mechanical arms cannot adjust the grasping range of the gripper, which is time-consuming and laborious. Reduce work efficiency, waste company funds, and reduce company revenue
