Operation type industrial robot joint and complete machine rigidity measuring and loading device

The utility model relates to an operation type industrial robot joint and whole machine rigidity measuring and loading device. Wherein the movable platform is used for loading movement of the whole device and mounting and supporting of corresponding equipment, and the power source is mounted on the movable platform, used for providing loading force, loading and unloading the loading force and keeping the loading force constant. And the tension loading part is arranged on the movable platform and is used for connecting a power source with the tail end of the robot joint so as to ensure correctapplication and transmission of tension and detection of a tension numerical value. The measuring device is simple in structure, not complex and easy to manufacture, and the defect that an existing measuring device cannot move is overcome through the movable platform. Besides, the tension direction is changed through the connection mode between the steel wire rope for free transformation and the ground wheel and the pulle
