Five-freedom-degree mechanical hand shaft arm based on rotation platform

Abstract

The invention discloses a five-freedom-degree mechanical hand shaft arm based on a rotation platform. The five-freedom-degree mechanical hand shaft arm comprises a rotating assembly, a first rotating seat body, a second rotating seat body, a third rotating seat body and a drive motor. The rotating assembly is horizontally placed. The first rotating seat body is placed on the rotating assembly. The second rotating seat body is rotationally connected to the first rotating seat body and is driven by a first motor arranged in the first rotating seat body to rotate. The third rotating seat body is connected to the second rotating seat body and is driven by a second motor arranged in the second rotating seat body to rotate. The drive motor is connected to one side of the third rotating seat body and is driven by a third motor arranged in the third rotating seat body to rotate. The output end of the drive motor is connected with a mechanical hand installation seat, and the drive motor drives the mechanical hand installation seat to rotate. By means of the five-freedom-degree mechanical hand shaft arm, movement flexibility is effectively ensured, a power and transmission mechanism internal installation structure is adopted, design is compact, and the space occupation amount is effectively reduced.

Description

technical field [0001] The invention relates to the field of automation, in particular to a five-degree-of-freedom manipulator shaft arm based on a rotating platform. Background technique [0002] The manipulator is a widely used automatic mechanical device. The motion control of the manipulator includes rotary motion, linear motion, etc. The flexible movement of the manipulator in the three-dimensional space is realized through the transmission of the shaft seat and the shaft arm; the traditional manipulator generally moves through the X, Y, and Z directions The linear motion combined with the rotary motion realizes the position movement. This type of motion requires a corresponding linear drive mechanism and a lifting mechanism. The structural design is complex, and the movement flexibility is not enough, so it cannot adapt to the occasions that require multi-angle processing, handling, and clamping; Traditional manipulator driving mechanisms such as motors and reducers ge...

[0002] The manipulator is a widely used automatic mechanical device. The motion control of the manipulator includes rotary motion, linear motion, etc. The flexible movement of the manipulator in the three-dimensional space is realized through the transmission of the shaft seat and the shaft arm; the traditional manipulator generally moves through the X, Y, and Z directions The linear motion combined with the rotary motion realizes the position movement. This type of motion requires the corresponding linear drive mechanism and lifting mechanism. The structure design is complex, and the motion flexibility is not enough, so it cannot adapt to the occasions that require multi-angle processing, handling, and clamping; Traditional manipulator driving mechanisms such as motors and reducers generally adopt an external installation structure, and the structural design is not compact, which makes the manipulator take up a lot of space
