Angular displacement sensor testing device

The utility model discloses an angular displacement sensor testing device. Belonging to the field of angular displacement sensors, including a machine frame, an electric appliance cabinet is fixedly mounted at the bottom of the inner wall of the rack; a PLC controller is arranged in the electric appliance cabinet; an air pump is fixedly mounted at the bottom of the inner wall of the rack; the output end of the PLC is electrically connected with the input end of an air pump, a clamping tool is fixedly installed at the top of the rack, an angle rotating tool is fixedly installed at the top of the rack, an air cylinder is fixedly installed at the top of the rack, the output end of the air pump is connected with the air cylinder, and the air cylinder is fixedly connected with the angle rotating tool. The sensor clamping device has the advantages that the situation that a sensor is not clamped in place can be avoided, and the problems that in the turning process, the manual turning effect is poor, and due to the f
