All electrical appliances of the utility model The equipment is powered by a built-in power supply 21. When a fault occurs in the CNC machine tool body 1, the motor 6 is started first. The rotation of the motor 6 will drive the rotating shaft 7 to rotate. The rotation of the rotating shaft 7 will drive the turntable 8 to rotate. The rotation of the turntable 8 will drive the connecting rod 9 to move. The movement of the connecting rod 9 will drive the sliding rod 11 to move up and down in the guide sleeve 22. The sliding rod 11 will repeatedly squeeze the movable plate 12. The squeezed and lowered movable plate 12 will drive the trigger rod 13 to trigger the switch 15 and turn on the warning light 17. Under the action of the reset spring 16, when the sliding rod 11 no longer squeezes the movable plate 12, the trigger rod 13 will leave the switch 15. At this time, the warning light 17 will be turned off, and the damper 23 can quickly dissipate the elastic potential energy of the reset spring 16 to prevent the reset spring 16 from rebounding repeatedly. Repeating this process, the warning light 17 will flash alternately, monitoring and warning of the fault of the CNC machine tool body 1, preventing subsequent operators from continuing to use the CNC machine tool body 1 to process parts.

[0022] Example 2: Reference Figure 2 , Figure 3 A first connecting shaft 18 is installed on the turntable 8, and a second connecting shaft 19 is installed on the slide bar 11. The first connecting shaft 18 and the second connecting shaft 19 are respectively movably installed at the two ends of the connecting rod 9. A power box 20 is installed on the CNC machine tool body 1. A built-in power supply 21 is arranged in the power box 20.

When the turntable 8 rotates, the connecting rod 9 will be driven to move, and the movement of the connecting rod 9 will drive the slide bar 11 to move up and down. Through the setting of the power box 20 and the built-in power supply 21, the built-in power supply 21 is installed in the power box 20.

Through the setting of the lampshade, the warning light 17 can be protected to prevent objects from touching the warning light 17 and causing damage to the warning light 17.

[0026] Working principle of the utility model: all electrical equipment of the utility model is powered by the built-in power supply 21. When the CNC machine tool body 1 fails, the motor 6 is started first. The rotation of the motor 6 will drive the rotating shaft 7 to rotate. The rotation of the rotating shaft 7 will drive the turntable 8 to rotate. The rotation of the turntable 8 will drive the connecting rod 9 to move. The movement of the connecting rod 9 will drive the sliding bar 11 to move up and down in the guide sleeve 22. The sliding bar 11 will repeatedly squeeze the movable plate 12. The squeezed and lowered movable plate 12 will drive the trigger rod 13 to trigger the switch 15 and turn on the warning light 17. Under the action of the reset spring 16, when the sliding bar 11 no longer squeezes the movable plate 12, the trigger rod 13 will leave the switch 15. At this time, the warning light 17 will be turned off, and the damper 23 can quickly dissipate the elastic potential energy of the reset spring 16 to prevent the reset spring 16 from repeatedly rebounding. Repeating this process, the warning light 17 will flash alternately, monitor and warn of the failure of the CNC machine tool body 1, and prevent subsequent operators from continuing to use the CNC machine tool body 1 to process parts.
