Cylinder, the 4th section is chuck structure, and middle and upper part, middle part and third section are an integral structure, the connection of third Duan Youyu chuck
Tapped through hole；Knife handle chuck (21) is contacted by the outer cone on top with main shaft (2), and blind rivet (22) passes through with knife handle chuck (21)
Engagement thread connection, when pulling claw (5) are shunk, pulling claw (5) tenses blind rivet (22), to make knife handle chuck (21) and main shaft
(2) it connects；Knife handle chuck (21) is connect by the tapped through hole of third section with chuck main body structure；This technical solution passes through knife
The direct-connected chuck main body structure of handle chuck (21) provides the rigidity of process system, machining accuracy without connecting by chuck end cap
It is higher；When executing tool changing movement, knife handle (17) can be changed to knife handle chuck (21), the second main shaft device (1b) is made to be changed into the
Four main shaft devices (1d)；Lathe becomes middle load turning cooked mode from Milling Process mode at this time；
4th main shaft device (1d) can obtain power by the keyway on main shaft (2) top, and then main shaft device rotates；For this purpose, if
The turnery processing for carrying out Smaller load, then select the first main shaft device (1a)；If carrying out Milling Process, the second main shaft device is selected
(1b)；If carrying out the turnery processing of big load, select third main shaft device (1c) if, carry out in load turnery processing,
Select the 4th main shaft device (1d)；
First main shaft device (1a), the second main shaft device (1b) and the 4th main shaft device (1d) can by way of replacing cutter phase
Mutually conversion, improves the efficiency of replacement；Third main shaft device (1c) can be by removal knife handle flange (6) or knife handle (17), and pacifies
The mode of ring flange (19) of the dress with chuck (7), from the first main shaft device (1a), the second main shaft device (1b) or the 4th main shaft
Device (1d) conversion is got；Correspondingly, removal has the ring flange (19) of chuck (7) and installs knife handle flange (6) or knife handle
(17) third main shaft device (1c) can be converted to the first main shaft device (1a), the second main shaft device (1b) or the 4th main shaft device
(1d)。
