Description

[0003] The motor in the driving system of the mechanical arm ground plate rotary platform operates, power is transmitted to the rotary support through the speed reducer, the rotary platform is driven to rotate around the central axis, so that the working direction of the mechanical arm is changed. The positioning and limiting device monitors the position and angle of the platform in real time, and the driving system stops working when the platform rotates to the set position, so that accurate positioning is realized.

[0004] At present, the mechanical arm ground plate rotary platform cannot adjust the height, so that the working height of the mechanical arm is fixed, and different height tasks cannot be flexibly coped with.

For example, in an automated production workshop, some high space may be idle because the mechanical arm cannot reach it, and enough flat space needs to be reserved for it when the equipment is laid out, causing waste of space resources.
