Mechanical carrying device based on three-degree-of-freedom parallel industrial mechanical arm

Abstract

The invention discloses a mechanical carrying device based on a three-degree-of-freedom parallel industrial mechanical arm. The mechanical carrying device is composed of a fixed base, a middle transmission mechanism and a tail end executor; the middle transmission mechanism is composed of three transmission branched chains; the first branched chain and the second branched chain are provided with aworm gear and worm mechanism; the worm gear and worm mechanism is arranged at the output part of a motor, and the first branched chain and the second branched chain jointly form a driving part for parallel movement of the tail end executor of the parallel mechanical arm; the third branched chain is provided with a gear transmission mechanism, the motor is driven by a gear and the output rotary motion is transmitted to an outer threaded rod, so that the inner threaded rod can be moved up and down through the spiral transmission, so that the tail end executor achieves the effect of fixed-axis rotation. According to the mechanical carrying device, based on the self-locking performance of the worm gear and worm transmission, the damage of parts such as the motor, caused by the fact that a carried object is too heavy, can be prevented, the worm gear and worm is large in transmission ratio and compact in structure, so that the mechanical carrying device is stable in transmission and relatively high in movement accuracy, and in addition, the mechanical carrying device has the characteristics of large speed reduction ratio, low noise and the like.

Description

technical field [0001] The invention relates to a manipulator, specifically a mechanical handling device based on a 3-degree-of-freedom parallel industrial manipulator. Background technique [0002] In many industries such as agriculture, industry, and service industries, there are more and more occasions for transporting human beings and large items, and the weight of the items being transported is also increasing. Due to the increase of labor costs and the advancement of technology, the transportation is often carried out by a robot or a handling device equipped with a robot. [0003] The problems existing in the existing technical solutions are: the manipulator or the handling device provided with the manipulator often bears a limited load, and because the transported items are too heavy, some parts such as the motor are overloaded and damaged. SUMMARY OF THE INVENTION [0004] The technical problem to be solved by the present invention is to provide a mechanical handl...
