One focus control, said focus control comprises the retainer plate that is installed on the retracting cylinder, the focusing lever that links to each other with retainer plate, said focusing lever comprise motion bar that is movably installed on the retainer plate and the folding rod that is connected with motion bar.
On the basis of technique scheme, said retainer plate stretches out and forms a fixed arm, and said motion bar is installed on the said fixed arm.
On the basis of technique scheme, a location screw is housed on the said fixed arm, said set screw is fixed in said motion bar on the fixed arm.
On the basis of technique scheme, what said folding rod rotated is fixed on the said motion bar.
On the basis of technique scheme, said folding rod is fixed in the end of said motion bar.
On the basis of technique scheme, said folding rod end is equipped with a rotating shaft, and said motion bar top is connected in the said rotating shaft.
On the basis of technique scheme, said motion bar be provided with one accommodate folding rod accepting groove.
On the basis of technique scheme, also be provided with the fastener of fastening said retracting cylinder on the said laser head main body.
The present invention also provides a kind of and uses above-mentioned a kind of laser cutting head that focus control is housed to confirm the method for focal length: the method for said definite focal length may further comprise the steps:
1) adjustment retracting cylinder height transfers to setting value with distance between focus lamp focus and the workpiece to be processed;
2) fixing retracting cylinder;
3) unclamp set screw, it is vertical with workbench to rotate folding rod to folding rod 46;
4) adjustment motion bar height makes folding rod contact with workpiece to be processed;
5) locked set screw, fixedly motion bar;
6) upwards folding rod is moved in upset.
Beneficial effect of the present invention is: laser head is provided with focus control; After adjusting the height of retracting cylinder when dispatching from the factory; Rotate folding rod to vertical with workbench; And folding rod is contacted with workpiece to be processed, use focus control to write down accurately behind the focal length the fixedly motion bar of focus control, and upwards upset is moved folding rod and is bumped against workpiece to avoid adding the man-hour folding rod.When needing focusing, put down folding rod, adjustment retracting cylinder height makes to correct contact workpiece before the folding rod and get final product.The whole operation process is simple, does not need the professional and technical personnel to debug, and the client can oneself accomplish whole debug process.
