Force sensor checking device and force sensor checking method

The invention discloses a force sensor checking device and a force sensor checking method. The force sensor checking device comprises a force sensor clamp, a suspension weight, a lifting platform and a motor control system. The force sensor clamp comprises a clamp support, a sensor installation structure and a force transmission connecting piece. The clamp support comprises a first support, a second support and a torque adjusting assembly. The lifting table and the motor control system are assembled on the first support. The sensor mounting structure is assembled on the first bracket or the second bracket and is used for fixing a to-be-measured force sensor, so that the to-be-measured force sensor measures force or torque; the force transmission connecting piece is connected with the sensor to be subjected to force measurement through a sensor mounting structure, the hanging weight comprises a weight tray and a standard weight, the weight tray is connected with the force transmission connecting piece, and the
