An improved mechanical arm device

Abstract

The improved mechanical arm device. The improved mechanical arm device comprises a base, wherein a first connecting arm is arranged at the top end of the base, one end of the first connecting arm is provided with a rotating shaft assembly, one side of the rotating shaft assembly is connected with a second connecting arm, and a take-up assembly is arranged at the top end of the second connecting arm. According to the improved mechanical arm device, the structure is scientific and reasonable, the use is safe and convenient, the take-up assembly is arranged, and the functions of a take-up box, atake-up wheel and a spring are achieved so that the mechanical arm connecting line coils can be conveniently wound into the take-up box to be hidden, abrasion caused by the fact that connecting linesare exposed to be wound or in contact with an external object is avoided; due to the elastic action of the spring, the connecting lines can be automatically tightened; and the rotating shaft assemblyis arranged, through the action of an elastic plate and balls, the balls can be conveniently in contact with a rotating shaft through the rotation of the rotating shaft so that the balls can roll andextrude a sponge layer, lubricating oil inside the sponge layer is guided to the surface of the rotating shaft, the rotating shaft is lubricated, the structure is simple, and the use is convenient andfast.

Description

technical field [0001] The invention relates to the technical field of mechanical arms, in particular to an improved mechanical arm device. Background technique [0002] The robotic arm is a multi-input multi-output, highly nonlinear, and strongly coupled complex system. Because of its unique operational flexibility, it has been widely used in industrial assembly, safety and explosion-proof fields, and in industrial manufacturing, medical treatment, entertainment services, It can be seen in fields such as military and space exploration. Although their shapes are different, they all have a common feature, that is, they can accept instructions and accurately locate a certain point in three-dimensional space for operations. Arms are divided into multi-joint robotic arms, rectangular coordinate robotic arms, spherical coordinate robotic arms, polar coordinate robotic arms, cylindrical coordinate robotic arms, etc. according to different structural forms. However, ordinary roboti...

Problems solved by technology

[0003] The present invention provides an improved mechanical arm device, which can effectively solve the problem that the ordinary mechanical arm needs to be rotated frequently during work in the above-mentioned background technology, thereby causing wear to the rotating shaft and affecting the normal operation of the device. The required connecting wires are exposed outside, and there is no special fixing device to fix them, which will easily cause the connecting wires to be entangled with each other, or the connecting wires will be damaged by friction with other objects, which will increase safety hazards, reduce the service life of the device, and increase costs.
