The lathe consists of a bed, headstock, tailstock, carriage, tool post and feeder. The workpiece is fixed between the headstock and the tailstock, and the workpiece is rotated based on the driving force generated by the headstock.

In general, the workpiece is fixed by a chuck (Chuck) located at the end of the main shaft, but if the workpiece is irregular shape can not be fixed by the chuck it is fixed using a face plate. This face plate is fixed with the turbine rotor using a fixing device, and the shape thereof varies depending on the shape of the workpiece. In other words, when the workpiece is relatively large, the shape of the face plate also increases accordingly, and when the workpiece is relatively small, the shape of the face plate also decreases accordingly. In addition, the shape of the portion to which the fixing device is coupled depends on the shape of the face plate. Therefore, conventionally, the face plate and the turbine rotor are combined by using a fixing device suitable for the shape of the face plate.

In addition, it is preferable to further include a vibration preventing portion for preventing the turbine rotor from vibrating by the vibration generated as the face plate rotates.

In addition, the anti-vibration portion, the coupling portion coupled to the other end of the fixed shaft; A fixing part formed on an outer side of the coupling part and coupled to the face plate to prevent vibration occurring in a rotation axis direction of the face plate; And a damper part formed inside the fixing part to prevent vibration generated in a direction perpendicular to the rotation axis of the face plate.

In addition, in order to prevent damage to the turbine rotor, it is preferable to form one surface of the fixed shaft in contact with the turbine rotor made of brass.

According to the present invention, by providing the adjusting sleeve with the outer surface inclined, the fixing device for the turbine rotor machining lathe can be easily closely attached regardless of the shape of the face plate. That is, the shape of the face plate used depends on the shape of the workpiece, and in order to couple the face plate and the turbine rotor, a fixing device suitable for the shape of the face plate should be used. In this case, when the adjustment sleeve is formed to have an inclined outer surface, the shape of the adjustment sleeve may be adjusted according to the shape of the face plate, so that the fixing device for the turbine rotor machining shelf may be easily adhered to the face plate.

After coupling the adjusting sleeve 20, the fixed sleeve 30 and the vibration preventing portion 40 to the fixed shaft 10, the control sleeve 20 is in close contact with the face plate 200. That is, the control sleeve 20 is rotated so that the control sleeve 20 is tightly coupled to the face plate 200. After tightly coupling the control sleeve 20 to the face plate 200, the fixed sleeve 30 is in close contact with the control sleeve 20 to maintain the coupling force of the face plate 200 and the control sleeve (20). This is the same case as combining two nuts to prevent loosening of the bolt, so that the fixing sleeve 30 is in close contact with the adjustment sleeve 20, thereby maintaining the coupling force of the face plate 200 and the adjustment sleeve 20 Can be.
