Abstract

Apparatus is disclosed for laser machining a work piece comprising a laser lens adapted to be releasably mounted to permit cleaning of the lens to remove any debris collected thereon during laser machining. The mounting includes a cylindrical base for defining a path along which the laser beam emitted by the laser source is directed onto the work piece, and a mounting member for mounting the laser lens with respect to the cylindrical base and adapted to be removably mounted on the cylindrical base in a manner whereby the lens is disposed to a certain position with respect to the cylindrical base. To this end, there is included a locking member engaging the cylindrical base and biasing the mounting member and its laser lens to the certain position with respect to the cylindrical base.

Claims17

Dependent claims

Apparatus for laser machining a work piece by precisely directing and focusing a laser beam onto the work piece, said laser machining apparatus comprising:

(a) a laser lens for focusing the laser beam onto the work piece;
(b) a cylindrical base for defining a path along which the laser beam passes to the work piece;
(c) a mounting member for receiving said laser lens adapted to be removably attached to said cylindrical base to permit cleaning of debris thrown off from the work piece during machining;
(d) means for securing said laser lens to said mounting member;
and
(e) locking means for releasably attaching said mounting member to said cylindrical base and for resiliently biasing said mounting member and therefor also its secured said laser lens so that said laser lens is precisely positioned at a certain position with respect to said cylindrical base.
