Concrete meaning in invention.
As shown in Figs. 1-3, the utility model provides the clamping workpiece device on a kind of lathe, including babinet（It is attached not shown
Go out）With main shaft 10, babinet is fixed on lathe bed, and main shaft 10 is rotatably arranged in the babinet.It is same with it that one is provided on main shaft 10
Axis and the through-hole 11 for running through its length direction, the interior sliding of through-hole 11 are provided with a connecting rod 12, and connecting rod 12 is coaxially set with main shaft 10
It sets, one end of connecting rod 12 extend out to outside main shaft 10 and connect with a cylinder 50, and cylinder 50 is fixed on lathe bed, and cylinder 50 can drive
Dynamic connecting rod 12 is moved along the axis direction of connecting rod 12.The other end of connecting rod 12 is connected with a circular cone 14, and circular cone 14 has circle
The conical surface.It is further sleeved with a driven gear 20 and a connector sleeve 30 on main shaft 10, driven gear 20 is by the driving that is arranged in babinet
Mechanism drives, and drives driven gear 20 to rotate by driving mechanism, to drive main shaft 10 to rotate, driven gear 20 and connector sleeve
30 is coaxially connected, i.e., driven gear 20 and connector sleeve 30 are kept fixed the relationship of connection.Connector sleeve 30 is at least part of to be located at
Outside babinet, it is set with an expansion sleeve 40 on connector sleeve 30, is detachably connected between expansion sleeve 40 and connector sleeve 30.Expansion sleeve 40
On be circumferentially provided with a plurality of expansion joint 41, expansion joint 41 is from the end face of one end of the separate connector sleeve 30 of expansion sleeve 40 to close to even
The end face of one end of female connector 30 extends certain distance, and the axis direction of the preferably extending direction with expansion sleeve 40 at expansion joint 41 is same
To the inner peripheral surface of expansion sleeve 40 is adapted with the circular cone 14.
Operation principle：As shown in Figure 1, before being put into workpiece to be processed 60, the piston rod of cylinder 50 stretches out, to the right by connecting rod 12
Certain distance is released, then workpiece to be processed 60 is sleeved on outside expansion sleeve 40, then the piston rod of cylinder 50 is withdrawn, to connect
Bar 12 retracts certain distance to the left, during connecting rod 12 is moved to the left, the inner peripheral surface of the circular cone 14 and expansion sleeve 40 of right end
It matches, is moved radially outwards to one end of separate connector sleeve 30 of expansion sleeve 40, and then by 60 stretching of workpiece to be processed
Or it clamps.It is then possible to which cylinder 50 is made to be disconnected relationship with connecting rod 12, cylinder 50 can also be made to keep rotation to connect with connecting rod 12
The relationship connect, herein under the premise of, driving mechanism drive driven gear 20 rotate, to main shaft 10 rotate, and then drive clamping exist
Workpiece to be processed 60 on expansion sleeve 40 rotates together.
Other than manual manipulation workpiece 60, the utility model only needs the action for controlling cylinder 50 to can be completed to workpiece 60
Clamping there is faster clamping speed therefore compared with traditional installation way by chuck to realize workpiece 60.
As being further improved for said program, the outside of the connector sleeve 30 is provided with multiple along the connector sleeve 30
The axial connection boss 31 being distributed at ladder, the expansion sleeve 40 can connect with a screw thread in multiple connection boss 31
It connects, the circular cone 14 is detachably connected with the connecting rod 12, and preferably circular cone 14 is threadedly coupled with connecting rod 12.When workpiece 60
When size difference, different expansion sleeves 40 can be easily replaced, while replacing corresponding circular cone 14, may be implemented in this way pair
The processing of the workpiece 60 of sizes, scope of application bigger.
As being further improved for said program, the end of the piston rod of the cylinder 50 is equipped with a sucker electromagnet 51,
Described one end of the connecting rod 12 is equipped with link block 13 made of soft magnetic material, and link block 13 is fixed with connecting rod 12 to be connected
It connects.As shown in figure 3, sucker electromagnet 51 is mainly made of shell 511, iron core 512 and coil 513,513 wound core of coil
512, iron core 512 is magnetized after coil 513 is powered, so as to be used to draw object.Iron core 512 is opposite with link block 13 to be set
It sets, when the sucker electromagnet 51 is powered, the link block 13 can be attracted by the sucker electromagnet 51, to make the gas
Cylinder 50 links together with the connecting rod 12.It can be with when connecting rod 12 is released to the right, between sucker electromagnet 51 and link block 13
It does not maintain the connection, when connecting rod 12 is retracted to the left, sucker electromagnet 51 is powered, to sucker electromagnet 51 and link block 13
It is pulled together, and then cylinder 50 can retract connecting rod 12, after connecting rod 12 is retracted, sucker electromagnet 51 powers off, cylinder 50
Continue to be moved to the left certain distance so that keep certain interval between sucker electromagnet 51 and link block 13, to connecting rod 12 with
The rotation of main shaft 10 will not be interfered by the piston rod of cylinder 50.Above-mentioned setting has simple and reasonable, easy to operate
Advantage.
