Six-axis spraying mechanical arm

Abstract

The invention discloses a six-axis spraying mechanical arm. The six-axis spraying mechanical arm comprises a mechanical arm body, wherein the mechanical arm body is provided with an airtight equipment cavity; the interior of the equipment cavity is sequentially connected to a first transmission mechanism, a second transmission mechanism, a third transmission mechanism, a fourth transmission mechanism, a fifth transmission mechanism and a sixth transmission mechanism in a transmission manner; each transmission mechanism is provided with a speed reducer located in the equipment cavity in a matching manner; at least one speed reducer is provided with a solid shaft; the speed reducer with the solid shaft is provided with a threading structure in a matching manner; the threading structure is provided with an airtight threading cavity; and the two ends of the threading cavity respectively communicate with the inner cavity of the transmission mechanism with the speed reducer with the shaft and the inner cavity of another transmission mechanism adjacent to the transmission mechanism with the speed reducer with the shaft. The six-axis spraying mechanical arm has the beneficial effects that the using safety can be improved; the internal space and manufacturing cost of the mechanical arm can be reduced to a certain degree; and the six-axis spraying mechanical arm cab be applied to automatic spraying industries.

Description

technical field [0001] The invention relates to the field of spraying manipulators, in particular to a six-axis spraying manipulator. Background technique [0002] The spraying environment in the spraying industry contains flammable and explosive gases, which requires high explosion-proof performance of the spraying manipulator, so the spraying manipulator is more expensive than ordinary manipulators. [0003] CN 103568002A discloses a six-axis freedom manipulator that can be used for automatic spraying, which has multiple transmission mechanisms, and each transmission mechanism is equipped with a reducer. Judging from the disclosed technology, the reducers are all non-hollow (with shaft) reducers, so the wires need to be routed from the outside of the manipulator body. The exposed motor wires will cause potential safety hazards, and the safety of the spraying environment cannot be guaranteed. [0004] In addition, some manipulators all use hollow reducers to drive each tra...

AI Technical Summary

Problems solved by technology

From the perspective of the disclosed technology, the reducers are all non-hollow (with shaft) reducers, so the wires need to be routed from the outside of the manipulator body. The exposed motor wires will cause safety hazards, and the safety of the spraying environment cannot be guaranteed.

[0004] In addition, some manipulators all use hollow reducers to drive each transmission mechanism, and the hollow reducer of the corresponding specification is about 50% more expensive than the non-hollow (with shaft) reducer, and the installation space required for the hollow reducer is large. , making the machine appear bulky
