Background technology
In the man-hour that adds of the critical components such as valve, need each end face of valve body, passage and valve body internal valve
Seat mounting seat is processed respectively.At present, each end face, passage, the processing of valve seat mounting seat in valve body
Time, when an end face and one end passage and side valve seat mounting seat process, valve body be unloaded from lathe
Under turn around clamping again, then the end face of the other end and passage and valve seat mounting seat are processed.Its shortcoming it
One is: clamping process affects valve body process velocity, and working (machining) efficiency is low；The two of its shortcoming are: clamping is all every time
There is site error, the processing of two valve seat mounting seats in two end faces of valve body and valve body produced coaxial error,
Affect valve body machining accuracy.
Summary of the invention
It is an object of the invention to the shortcoming existed for prior art, it is provided that it is complete that a kind of clamped one time realizes valve body
Portion's machined surface, the automatic rotary indexing processing unit (plant) that working (machining) efficiency is high, Product Precision is high.
Technical scheme includes chuck, claw, and claw is made up of upper clipping claw and lower claw；Mainly
Upper clipping claw is movably arranged in the axis hole of clamping piston by installing axle, and clamping piston is arranged on the clamping on chuck
In oil cylinder；Lower claw is connected with the shaft hole matching on rotation dish by installing axle, and rotation dish is axially pacified by locating piece
Being contained on chuck, rotation dish is radially dynamic with chuck installing hole inwall to be coordinated；Section in rotation dish external cylindrical surface
Put and make polygon cylinder, the chuck of polygon cylinder side is provided with the first oil cylinder and the second oil cylinder, the
One in-oil cylinder first piston end and the second in-oil cylinder second pistons end extend into polygon cylinder respectively
A plane in, first piston and the second piston use hydraulic system interaction to control.
In above technical scheme, the side of first piston and the second pistons end is formed respectively with and polygon post
The inclined-plane that the plane of body cooperates, the opposite side of first piston end is shaped with puts down with the second pistons end inclined-plane
The inclined-plane of row.
In above technical scheme, equipped with journal bearing between rotation dish radial direction and chuck installing hole inwall, turn
Equipped with plane bearing between Moving plate end face and chuck installing hole bottom surface；The installation axial end of upper clipping claw is lived with clamping
Installation end spherical bearing between the axis hole bottom surface of plug.
The present invention compared with prior art provides the benefit that workpiece is passed through clamping cylinder by upper clipping claw and lower claw
Being installed on rotation dish, rotation dish uses the first oil cylinder and the second oil cylinder pushing to rotate, and clamped one time can be complete
Become the processing of multiple, decrease the clamping workpiece time, it is to avoid clamping workpiece error, there is working (machining) efficiency
Height, mismachining tolerance are few, machining accuracy advantages of higher.

Detailed description of the invention
Automatic rotary indexing processing unit (plant) as shown in Figure 1, including chuck 1, claw, claw is by upper clipping claw
12 and lower claw 13 form, be clipped on lathe outside chuck 1；Upper clipping claw 12 is installed by installing axle activity
In the axis hole of clamping piston 6, making can relatively rotate between upper clipping claw 12 and clamping piston 6, clamping is lived
In the clamping cylinder 14 that plug 6 is arranged on chuck 1, hydraulic drive clamping piston 6 make upper clipping claw 12 He
Lower claw 13 clamps workpiece, upper clipping claw 12 and lower claw 13 and can select to change accordingly according to the shape of workpiece
Shape；Lower claw 13 is connected with the shaft hole matching on rotation dish 9 by installing axle, and rotation dish 9 is axially by fixed
Position block 7 is arranged on chuck 1, and rotation dish 9 is radially dynamic with chuck 1 installing hole inwall to be coordinated, and makes rotation dish 9
Radially can rotate in chuck 1 installing hole, and axially be fixed；Section in rotation dish 9 external cylindrical surface
Put and make polygon cylinder, polygon cylinder can according to rotation dish 9 anglec of rotation need be designed to four limits
Shape cylinder or hexagon cylinder, be provided with the first oil cylinder 16 and the second oil on the chuck 1 of polygon cylinder side
Cylinder 15, first piston 3 end in the first oil cylinder 16 and the second piston 4 end portion in the second oil cylinder 15
Not extending in a plane of polygon cylinder, first piston 3 and the second piston 4 use hydraulic system mutual
Dynamic control, i.e. while hydraulic system promotes first piston 3 to push away forward, the second piston 4 is drawn back, and
When second piston 4 pushes away forward, first piston 3 is drawn back, and makes first piston 3 and the second piston 4 protect all the time
Hold one to contact with a face of polygon cylinder, it is achieved to the rotation of rotation dish 9 with from lock control.
The side of first piston 3 and the second piston 4 end is formed respectively with the plane phase interworking with polygon cylinder
The inclined-plane closed, the opposite side of first piston 3 end is shaped with the inclined-plane parallel with the second piston 4 end chamfer,
Make to keep between first piston 3 and the second piston 4 good being mutually shifted, and first piston 3, second is lived
Good plane contact is kept between plug 4 and rotation dish 9.
Equipped with journal bearing 8, rotation dish 9 end face and card between rotation dish 9 radial direction and chuck 1 installing hole inwall
Equipped with plane bearing 10 between dish 1 installing hole bottom surface, reduce the spin friction between rotation dish 9 and chuck 1
Power；Installation end spherical bearing between installation axial end and the axis hole bottom surface of clamping piston 6 of upper clipping claw 12, reduces
Rotating friction force between upper clipping claw 12 and clamping piston 6.By piston between clamping cylinder 14 and chuck 1
End cap 5 seals, respectively by first piston lid 2 and between first oil cylinder the 16, second oil cylinder 15 and chuck 1
Two piston cap 17 seal, and the end face of rotation dish 9 is axially installed on chuck 1 by bottom 11.Card
Dish 1, claw, rotation dish 9, clamping piston 6, first piston the 3, second piston 4 all use steel alloy warp
Overheating Treatment, improves product mechanical performance and extends product service life.
