According to an embodiment of the present invention, an apparatus for sensing subsidence of a bed, capable of checking the state of the bed in real time, detecting an error in horizontality of a tool machine when the error occurs, and notifying the user of the error. According to an embodiment of the present invention, the apparatus for sensing subsidence of a bed comprises: a housing; a mass body; a bracket; and a sensor; and a control part. The housing is attached to the bed. The mass body is received in the interior of the housing and is fixated to the upper surface of the housing by a wire. The sensor measures a movement amount of the mass body. The bracket fixes the sensor to the housing. The control part transmits/receives data on the movement amount of the mass body to/from the sensor to calculate the angle of subsidence. When the bed subsides, the mass body maintains a state vertical to the ground surface. The housing and the sensor are slanted in the direction where the bed subsides. |
