Abstract
The invention discloses a kind of method that fixture center of rotation overlaps with specified point on workpiece, comprise step 1: range estimation, specified point on workpiece is moved to fixture center of rotation, and clamps workpiece；Step 2: indicate the position A of specified point on now workpiece with needle point；Step 3: fixture is rotated 180 degree, and now on workpiece, specified point position is B；Step 4: be simultaneously irradiated on A, B point with laser rule, and read the scale at A, B midpoint；Step 5: keep laser rule motionless, the x-axis of movable clamp and y-axis, make specific point on workpiece move to A, B midpoint of laser rule instruction；Step 6: indicate the position AA of specified point on now workpiece with needle point；Step 7: fixture is rotated 180 degree, and now on workpiece, specified point position is BB；Step 8: if AA Yu BB is misaligned jumps to step 2, if AA with BB overlaps, terminate.Specified point gap before and after fixture center of rotation rotates on workpiece is reduced, until gap is zero so that fixture center of rotation overlaps with specified point on workpiece by constantly adjusting.
Description
Technical field
The present invention relates to a kind of location of workpiece method that adjusts, particularly a kind of fixture center of rotation and specified point weight on workpiece
The method closed.
Background technology
The center of rotation of fixture is a specific referential, can position the workpiece of clamping on fixture.Workpiece
On specified point usually workpiece on there is the focus in certain face on centrage and the workpiece of revolution feature.When in the rotation of fixture
When the heart overlaps with specified point on workpiece, rolling clamp, the workpiece center of rotation that also specified point represents on workpiece rotates.
This workpiece to processing with revolution feature is highly useful, and such cutter is motionless, and workpiece rotates can process institute
The revolution feature needed.
At present, the workpiece to this processing revolution feature is the workpiece the most accurate with expensive coordinate measuring machine
Positioning datum realizes, and this can solve problem, but cost is the highest.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of method that fixture center of rotation overlaps with specified point on workpiece,
The method that this fixture center of rotation overlaps with specified point on workpiece can be exactly by fixture center of rotation and specified point on workpiece
Adjust and overlap.
In order to realize foregoing invention purpose, the method that present clip center of rotation overlaps with specified point on workpiece, comprise
Step 1: range estimation, moves to fixture center of rotation by specified point on workpiece, and clamps workpiece；Step 2: indicate now work with needle point
The position A of specified point on part；Step 3: fixture is rotated 180 degree, and now on workpiece, specified point position is B；Step 4: use laser
Rule is simultaneously irradiated on A, B point, and reads the scale at A, B midpoint；Step 5: keep laser rule motionless, movable clamp
X-axis and y-axis, make on workpiece specific point move to A, B midpoint of laser rule instruction；Step 6: indicate now with needle point
The position AA of specified point on workpiece；Step 7: fixture is rotated 180 degree, and now on workpiece, specified point position is BB；Step 8: as
Really AA Yu BB is misaligned jumps to step 2, if AA with BB overlaps, terminates.
Specified point gap before and after fixture center of rotation rotates on workpiece is reduced, until gap is by constantly adjusting
Zero so that fixture center of rotation overlaps with specified point on workpiece.
Detailed description of the invention
The method that present clip center of rotation overlaps with specified point on workpiece, comprises step 1: range estimation, by special on workpiece
Fixed point moves to fixture center of rotation, and clamps workpiece；Step 2: indicate the position A of specified point on now workpiece with needle point；Step
Rapid 3: fixture is rotated 180 degree, and now on workpiece, specified point position is B；Step 4: be simultaneously irradiated to A, B point with laser rule
On, and read the scale at A, B midpoint；Step 5: keep laser rule motionless, the x-axis of movable clamp and y-axis, make on workpiece special
Fixed point moves to A, B midpoint of laser rule instruction；Step 6: indicate the position AA of specified point on now workpiece with needle point；
Step 7: fixture is rotated 180 degree, and now on workpiece, specified point position is BB；Step 8: if AA Yu BB is misaligned jumps to step
2, if AA with BB overlaps, terminate.
Specified point gap before and after fixture center of rotation rotates on workpiece is reduced, until gap is by constantly adjusting
Zero so that fixture center of rotation overlaps with specified point on workpiece.
Claims (1)
1. the method that fixture center of rotation overlaps with specified point on workpiece, it is characterised in that: comprise step 1: range estimation, by workpiece
