Motor drive multi-shaft combined mechanical arm system

Abstract

The invention relates to a motor drive multi-shaft combined mechanical arm system which comprises a horizontal direction one-shaft mechanical arm arranged at the top end of a vertical direction one-shaft mechanical arm. The horizontal direction one-shaft mechanical arm and the vertical direction one-shaft mechanical arm are movably connected through a rotating shaft assembly, and the horizontal direction one-shaft mechanical arm is made to rotate. The horizontal direction one-shaft mechanical arm comprises a gear outside a ball bearing and a motor driving mechanism on a mechanical arm base. The motor driving mechanism comprises a worm gear, teeth of the worm gear are engaged with wheel teeth of a gear outer ring, so that the worm gear is rotated and drives the gear, and the gear drives a rotating assembly of the horizontal direction one-shaft mechanical arm to rotate. The multiple sets of mechanical arms which can achieve multi-shaft work can be formed, one one-shaft mechanical arm isinstalled on the other one-shaft mechanical arm, one or more one-shaft mechanical arms are directly assembled according to requirements of the machining technology of a machining machine tool, the requirements for replacement of the whole mechanical arm are lowered, the shaft number of the mechanical arms can be freely increased or decreased conveniently according to different requirements, and the application range is wider.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment control, in particular to a motor-driven multi-axis combined mechanical arm system. Background technique [0002] With the development of modern industry, in order to improve production efficiency, stabilize and improve product quality, improve the working conditions of workers, and accelerate the realization of industrial production mechanization and automation, mechanical arms with different purposes have been produced and widely used in the production process. Especially in some specific occasions, the mechanical arm has been widely used. [0003] The robotic arm has become a new technology in the field of automatic control, and has become an important part of the modern industrial production system. The extension and expansion of the mechanical arm can replace skilled workers in many fields to work in harsh environments such as dangerous, harmful, toxic, low temperature and high ...

Problems solved by technology

[0004] However, the movement methods of many traditional mechanical arm devices are unreasonable, and their movement in space is often restricted, or in other words, they cannot move to any angle or direction in a certain space to meet the needs of actual industrial production. This limitation greatly affects its application range and places

[0005] Those skilled in the art have analyzed the defects of the existing known technologies and found that most of the existing mechanical arms are single-axis or multi-axis mechanical arms. Axis or multi-axis manipulators, if the number of axes of the manipulator is arbitrarily increased or decreased according to different usage requirements, many manipulators will be equipped with corresponding auxiliary equipment or combined with different manipulators, resulting in complex production methods , the production cost is relatively high, for example, there is no simple and effective way to make the mechanical arm realize the rotation adjustment between the horizontal plane and the vertical plane
