Disk, for usual chuck on the head of lathe, angling cylinder is mounted in the tail portion of lathe, and centre is coupled using pull rod, passes through piston
Axial movement so that chuck jaws generation is moved radially, workpiece is pressed from both sides with pine, which makes headstock axial length longer, cause this
The installation and repair of class lathe angling cylinder are all highly difficult.
Utility model content
The utility model can make lathe headstock axially shorter in view of the shortcomings of the prior art, offer is a kind of, angling cylinder installation
With preposition rotary cylinder formula oild chuck easy to maintenance.
In order to solve the above technical problems, the utility model is addressed by the following technical programs：Before on a kind of lathe
Rotary cylinder type oild chuck is put back into, including is set to the spindle flange of front-end of spindle, chuck, piston rod flange, piston rod, piston,
The rotating shaft with rotary joint of cylinder body, claw, claw insert, the bearing body being set in the middle part of main shaft and rear-end of spindle setting,
Driving wheel is arranged with the rotating shaft of rotary joint, is located at turn around on axis and is provided with oil inlet and outlet and anti-rotation bar, piston rod and revolution
Axis passes through the oil pipe unicom in main shaft.
In said program, it is preferred that the oil inlet and outlet includes the first oil inlet and outlet and the second oil inlet and outlet.
In said program, it is preferred that the oil pipe includes the first oil pipe and the second oil pipe.
In said program, it is preferred that the cylinder body outer circle is the cone with T-slot.
In said program, it is preferred that annular is provided with T-slot on the chuck end face, and chuck end face is perpendicular to master
Shaft centre line.
In said program, it is preferred that the center line of T-slot is vertical with spindle centerline on the chuck end face.
In said program, it is preferred that the setting quantity of chuck end face T-slot and the T-slot quantity one of cylinder body outer circle
It causes.
In said program, it is preferred that the quantity of the claw is consistent with the T-slot quantity of cylinder body outer circle.
In said program, it is preferred that be provided on the claw and match with the T-slot on chuck end face and cylinder body outer circle
The slot of conjunction.
Compared with prior art, the utility model has the advantages that：This is simple, compact and reasonable for structure, this is preposition
Formula chuck is integral for connecting cylinder body and chuck, is mounted in spindle nose, can not only reduce labor intensity, when shortening clamping
Between, productivity is improved, and cylinder body is installed and repaired more convenient.
Description of the drawings
Fig. 1, the utility model structure end view.
A-A cross section views in Fig. 2, Fig. 1.
Specific implementation mode
The utility model is described in further detail with specific implementation mode below in conjunction with the accompanying drawings.
Shown in Fig. 1 to Fig. 2, the preposition rotary cylinder formula oild chuck on a kind of lathe, including it is set to 3 front end of main shaft
Spindle flange 4, chuck 5, piston rod flange 6, piston rod 7, piston 8, cylinder body 9, claw 10, claw insert 11 is set to master
The bearing body 2 at 3 middle part of axis and the rotating shaft 16 with rotary joint 17 of 3 rear end of main shaft setting, driving wheel 15 are arranged with revolution
The rotating shaft 16 of section 17, is located at turn around on axis 16 and is provided with oil inlet and outlet and anti-rotation bar 20, piston rod 7 passes through with rotating shaft 16
Oil pipe unicom in main shaft.
The oil inlet and outlet includes the first oil inlet and outlet 19 and the second oil inlet and outlet 18, and the oil pipe includes the first oil pipe 13
With the second oil pipe 14,9 outer circle of the cylinder body is the cone with T-slot, and annular is provided with T-slot on 5 end face of the chuck, and
And 5 end face of the chuck center line of T-slot and 3 central axis of main shaft, institute on 3 center line of main shaft, 5 end face of the chuck
The setting quantity for stating 5 end face T-slot of chuck is consistent with the T-slot quantity of 9 outer circle of cylinder body, quantity and the cylinder body 9 of the claw 10
The T-slot quantity of outer circle is consistent, is provided on the claw 10 and is matched with the T-slot in 9 outer circle of 5 end face of chuck and cylinder body
Slot.
When work, the second oil inlet and outlet 18 connects high-pressure oil pipe, and high pressure oil flows to the thrust of piston 8 by the second oil pipe 14
Chamber so that cylinder body 9 leaves chuck 5, to drive claw 10 to clamp to 3 center of main shaft, achievees the purpose that clamp workpiece；On the contrary
, when the first oil inlet and outlet 19 is connect high-pressure oil pipe, high pressure oil can pass through the pulling force chamber that the first oil pipe 13 flows to piston 8, make cylinder
Body 9 is close to chuck 5, drives claw 10 to leave 3 center of main shaft, reaches swelling workpiece purpose.
