Need the projection size in these system holes being converted to the exercisable surface size of workman, so
Scribing operation can be carried out, the follow-up tap operation of covering is completed.The operational sequence is cumbersome, and efficiency is low.
The content of the invention
Present invention solves the technical problem that：There is provided that a kind of process is simple, the ball-type covering of efficiency high
The method that hole bit line complement is drawn.
The technical scheme is that：A kind of method that ball-type covering hole bit line complement is drawn, it is described
The coordinate of the known coordinate system lower opening by origin of the centre of sphere of method, it is characterized in that described method bag
Include following steps：
Step one, ball-type covering is fixed by the fixed axis of symmetry and centre of sphere axis, and root
The distance of the pitch-row centre of sphere is calculated according to coordinate value of the hole under the coordinate system；
Step 2, the distance tried to achieve using in step one is radius, around ball-type covering centre of sphere axis,
A circular arc line is obtained on ball-type covering, and obtains the intersection point of the axis of symmetry and the circular arc line；
Distance of the intersection point of step 3, the calculating axis of symmetry and the circular arc line to hole；
Step 4, according to the distance determined in step 3, the friendship by the center of circle of the intersection point to determine
Distance of the point to hole is radius, another circular arc line is obtained on ball-type covering, and in step 2
The intersection point of obtained circular arc line is the position in hole.
Improved as one kind of the technical program, spherical covering is fixed in frock, and the frock is opened
There is the concave surface coordinated with spherical covering.
Improved as one kind of the technical program, frock is marked with benchmark corresponding with spherical covering
Line, spherical covering is fixed in frock according to the datum line, and axis is additionally provided with frock
The rotation sample coordinated with spherical covering concave surface is fixed with the rotating shaft overlapped with centre of sphere axis, rotating shaft
Plate.
As the technical program one kind improve, determine after distance of the centre of sphere away from hole, with it is spherical
Covering concave surface coordinate rotation model cambered surface on determine away from rotating shaft distance with this apart from identical point,
And rotation model is rotated around the shaft, the track of the point is obtained circular arc.
Beneficial effects of the present invention：By correspondence frock as secondary scribe instrument, rotation is installed
Axle, exercisable surface size is converted to by inoperable projection size.Also, operative employee
Sequence is simple, efficiency high.
