Abstract
The utility model relates to a belleville spring system, and especially relates to the belleville spring system of an engraving machine tailstock. The system comprises a main shaft equipped with a shaft hole. A sleeve is sleeved outside the main shaft. The tail portion of the main shaft and the tail part of the sleeve are positioned via a rear inner end cover. The upper portion of the sleeve is provided with a press block. The rear inner end cover is provided with a rear outer end cover fixed with the press block. The shaft hole of the tail portion of the main shaft is provided with a screw rod. The screw rod extends out of the rear outer end cover. A constant force ring is arranged between the tail portion of the screw rod and the rear outer end cover. A belleville spring is arranged between the constant force ring and the rear outer end cover. The belleville spring system of the engraving machine tailstock is simple in structure and good in use effect.
