Specific implementation mode
With reference to specific embodiments and the drawings, the utility model is described in further detail.
As shown in the figure：Based on the spherical surface processing tool of lathe in machining V-type semicircle valve ball, including pedestal 1 and plug 2,
Pedestal 1 includes disk 13 and the fixed block 11 and core print seat 12 that are fixed on disk 13, be additionally provided on pedestal 1 with fixed block 11 and
The coaxial movable block 3 of core print seat 12.Fixed block 11 and core print seat 12 are equipped with internal spline, and the middle part and head of plug 2 are equipped with external splines；
The middle part of plug 2 is inserted into core print seat 12, and the head of plug 2 close to fixed block 11 and is cased with split washer 4.It is set on movable block 3
Have to push 2 tail portion of plug holds out against structure 5, specifically, the upper end center in movable block 3 is provided with threaded hole, holds out against structure 5
For the screw in threaded hole.The tail portion of plug 2 is equipped with block 21, conveniently holds out against 5 pushing tow of structure.To ensure V-type semicircle
For 7 cutting spherical surface of valve ball without interference, the height of the tail portion of plug 2, movable block 3 and fixed block 11 is less than the rotation of V-type semicircle valve ball 7
Centerline height.2 head of plug is equipped with step close to one end of core print seat 12, and split washer 4 is sleeved on step, its position is avoided to move
It is dynamic.4 shape of split washer is annular U formulas, convenient for assembly and dismounting.
The course of work：The utility model coordinates numerically controlled lathe to use, and can lathe model clamping tooling circle by lathe chuck
Depending on disk 13,7 other processes of V-type semicircle valve ball are complete, and drop pass face is undressed, and spherical surface is in casting plane.Tooling base 1 is pacified
On digital control lathe chuck, 1 outer circle of pedestal is corrected with dial gauge, keeps chuck hub concentric with the outer circle of pedestal 1, last claw
It clamps.
Using 1 outer circle of pedestal as lathe X-axis to knife point.Plug 2 is inserted into core print seat 12, most with 2 outer round surface of plug
High point is as Z axis to knife point.Coordinate of the valve ball in tooling is set in lathe parameter.
As shown in fig. 6, by the splined central aligning tool fixation motion block 11 of V-type semicircle valve ball 7, in the internal spline of core print seat 12
Then plug 2 with external splines is inserted by the heart, while ensureing that 2 tail portion end face of plug is parallel with 1 face of disk, plug 2
External splines when being inserted into V-type semicircle 7 internal spline of valve ball, ensure V-type semicircle valve ball 7 close to opening V end face with 1 face of disk
It is parallel.Movable block 3 is fixed on hexagon-headed bolt 6 on disk 13,2 one end insertion opening baffle ring 4 of plug, in last movable block 3
Between threaded hole placement hold out against structure 5 i.e. screw.Tightening this screw makes it withstand 2 tail end face of plug, and plug 2 then drives opening
Baffle ring 4, split washer 4 then drive V-type semicircle valve ball 7 to move forward, V-type semicircle valve ball 7 are finally made to withstand 11 one end of fixed block
Face can not move.V-type semicircle valve ball 7 positions completely in tooling at this time, and six-freedom degree can not move.
Because processing is workpiece rotation processing, cutting force is to spread around, and the power transmitted by inner bolt ensures V-type half enough
The depressed knife not loose phenomenon in cutting of round valve ball 7.Editor's quadrant program can process spherical surface, wherein only V-type is open
A distance ensure that and interrupted cut is not present within the scope of ball face sealing there are interrupted cut.It is using digital control system editable
Roughing and finishing procedures ensure spherical surface roughness and spherical surface circularity.Sealing surface lines side of the cutting spherical surface lines with valve seat
