[0026] A buffer groove 2 is provided inside the base 1 , a buffer plate 19 is installed at the middle position of the bottom end of the CNC inverter body 3 , and a rubber buffer pad 18 is bonded and fixed to the bottom end of the buffer plate 19 .
[0027] Buffer columns 14 are installed on both sides of the bottom end of the CNC inverter body 3, and the outer walls of the buffer columns 14 are connected to buffer springs 15. Buffer seats 16 are installed on both sides of the bottom end of the inner wall of the buffer groove 2, and guide rails 17 are installed on both sides of the inner wall of the buffer seat 16.
[0028] The buffer columns 14 are symmetrically distributed about the central axis of the CNC inverter body 3, and the buffer seats 16 are symmetrically distributed about the central axis of the buffer slot 2;
[0029] Furthermore, the exhaust port 4 is equipped with a valve inside to control opening and closing, so as to prevent the airflow from entering the inside of the CNC inverter body 3 when it is opened for a long time, and the exhaust port 4 works synchronously with the drive motor 6;
[0030] Furthermore, the buffer plate 19 cooperates with the rubber buffer pad 18 to achieve the bottom buffering capability. A slider is installed on the side of the bottom end of the buffer column 14. The slider cooperates with the guide rail 17 to form a sliding guide connection between the two.
