Light-weight six-shaft universal robot

Abstract

The invention relates to a light-weight six-shaft universal robot. A shaft seat is fixedly arranged on an arm shaft, a shaft seat protecting box is fixedly arranged on the shaft seat, a third-shaft driving motor, a fourth-shaft driving motor, a fifth-shaft driving motor and a sixth-shaft driving motor are arranged in the shaft seat protecting box, a small-arm rod casing and a small-arm lengthening rod casing are respectively and fixedly arranged at the front part and the back part of a small-arm speed reducer, a sixth shaft is inserted and sheathed in a fifth shaft, the fifth shaft is inserted and sheathed in a fourth shaft, the fourth shaft is inserted and sheathed into the small-arm rod casing, the small-arm speed reducer and the small-arm lengthening rod casing, a fourth-shaft driven gear, a fifth-shaft driven gear and a sixth-shaft driven gear are respectively and fixedly arranged on the fourth shaft, the fifth shaft and the sixth shaft, and the length of the small-arm rod casing is smaller than 100mm. The light-weight six-shaft universal robot has the advantages that the torque load required by the self weight is effectively reduced, the traditional balance cylinder device is not needed, the balance of a swinging arm during the work can also be met, and the machine structure is simplified. The effective protection effect on a motor is also realized through a tight protecting cover.

Description

Technical field: [0001] The invention relates to the technical field of robots, and more specifically relates to a general-purpose robot with the functions of welding, pouring, and handling, and a carrying capacity of 70 kilograms. Background technique: [0002] Most of the long-armed robots on the market require additional balance devices. The reducer on the arm is biased toward the middle end of the arm, and its own structural volume is relatively large, which will increase the difficulty of installing the protective device and increase the production cost of the robot. A series of advanced questions. Invention content: [0003] The purpose of the present invention is to address the deficiencies of the prior art, and to provide a light-duty six-axis universal robot. Its novel forearm structure makes the fuselage smaller and more effectively reduces the torque load required by its own weight. Due to its small body, the robot does not need a traditional balance cylinder d...
