Robot static flexibility testing device and testing method

The invention discloses a robot static flexibility testing device and method, the testing method is that the testing device is used for testing the static flexibility of a robot, the testing device comprises a hook, a switching mechanism, a push-and-pull meter and a linear displacement platform, the hook is connected with the push-and-pull meter through the switching mechanism, the push-and-pull meter is carried on the linear displacement platform, and the linear displacement platform is connected with the switching mechanism. The switching mechanism comprises a plurality of pulley units, and different pulley units respectively correspond to different testing directions. A load can be applied to the tail end of the detected robot through the hook by means of the arranged linear displacement platform, and the magnitude of the load applied to the robot can be monitored through the push-pull meter so as to control the linear displacement platform to move. The direction of the acting force loaded on the tested ro
