The protection airbag is disposed at one side of the moving panel 31 and electrically connected to the controller. The detector 35 is electrically connected to the controller, and outputs a detection signal obtained by the detection to the controller. The controller controls the working states of the protective airbag and the driving motor according to the detection signal obtained by the detector 35.
In this embodiment, the air bag moving unit is installed in the longitudinal direction of the machine 1, and the detector 35 is installed at the side in the longitudinal direction in the table 2 of the numerical control machine.

Specifically, the other side wall surface of each guide rail opposite to the side allowing the mobile panel 31 to be installed is provided with a guide groove, and the same end of each guide rail is provided with an opening allowing the mobile panel 31 to penetrate out of the guide rail due to movement. The connection between the driving mechanism 33 and the moving panel 31 is located in the guide groove, and can be controlled by the controller to drive the moving panel 31 to move along the guide groove of the two guide rails 32.

The cover plate includes two plate bodies (312 and 313) hinged to the inner walls of the two sides of the opening of the receiving groove 311. When the protective airbag is in an uninflated state, the two cover plates cover the opening of the accommodating groove 311 to close the accommodating groove 311; when the protective airbag is in an inflated state and the volume of the protective airbag is larger than that of the accommodating groove 311, the protective airbag pushes the two cover plates open and extends out of the accommodating groove 311.
Specifically, the protective air bag comprises an air bag body 34 provided with an air inlet and an air outlet, and a dual-purpose pump for air suction and inflation; the inflation port of the dual-purpose pump for air suction and inflation is connected with the air inlet of the air bag body 34 in a sealing and communicating manner, the air suction port of the dual-purpose pump for air suction and inflation is connected with the air outlet of the air bag body 34 in a sealing and communicating manner, the dual-purpose pump for air suction and inflation is electrically connected with the controller, and the controller controls the working state of the dual-purpose pump for air suction and inflation according to a detection signal detected by the detector 35.
