During the movement of the spindle box 1, vibrations will be generated, and the rubber plate 40 can absorb and offset the vibrations. At the same time, when the vibration amplitude is too large, it will drive the sliding block 42 to slide inside the sliding groove 41. When the sliding block 42 moves, it will pressurize the buffer spring 43 and the damper 44, and then the buffer spring 43 and the damper 44 cooperate to alleviate the impact force generated, thereby effectively avoiding the generation of vibrations and prolonging the time. The service life of the C-axis feed indexing device for high-precision CNC vertical turning and milling machine tools is extended. When the workpiece is processed and the impurities adsorbed on the chuck 6 are removed, the servo motor 4 moves, which will drive the drive shaft 3 to move. The drive wheel 7 and the driven wheel 9 cooperate to drive the micro-blower 8 to move. The micro-blower 8 moves to extract the outside air through the air intake pipe 10. After the outside air flows through the No. 1 filter 11 and is filtered, it will flow into the micro-blower 8. The air transported by the micro-blower 8 will cause the wind to flow into the diversion box 20. The wind will flow into the diversion pipe 14 through the exhaust pipe 21. The diversion pipe 14 cooperates with the air intake head 18 to cause the wind to flow into the flow pipe 17. The wind in the flow pipe 17 When flowing, it will carry heat with it, thereby improving the heat dissipation efficiency of the C-axis feed indexing device for high-precision CNC vertical turning and milling machine tools. The wind force flowing inside the flow tube 17 will flow into the air collecting groove 15 through the exhaust head 19, and will flow into the cleaning nozzle 30 through the conveying pipe 45. The wind will flow to the surface of the chuck 6 through the cleaning nozzle 30 to remove the adsorbed matter on the surface of the chuck 6. The angle of the cleaning nozzle 30 can be adjusted by the operation of the micro motor 29, thereby improving flexibility. After the wind force enters the diverter box 20, the wind force inside the diverter box 20 will flow into the exhaust pipe 21 and the connecting groove 34 respectively, and will flow into the exhaust pipe 33 through the connecting groove 34.Then, the wind will flow into the spindle box 1 through the air outlet head 35. When the wind flows inside the spindle box 1, it will carry heat. The wind carrying heat will flow into the concave groove 37, and then the wind will flow to the outside through the exhaust head 38, thereby improving the heat dissipation efficiency. When the ball valve 31 is turned to close the exhaust pipe 21, the wind entering the diverter box 20 will all flow into the exhaust pipe 33, thereby accelerating the flow speed of the wind flowing inside the air outlet head 35, and then the wind will quickly flow into the surface of the spindle box 1, which can remove the adsorbed substances on the surface of the spindle box 1.
