Definitions
- the invention relates to a device for laser coating internal component surfaces with an additional powdery material, in particular the preamble of claim 1.
- Supply lines for cooling media are also integrated in the lance, Powder material, protective gas and a purge gas to generate a Exit window of the laser beam at the tip of the lance, free-blowing cross jets.
- the coating is done by immersing the lance in the cylinder bore, the powder being blown out to the coating location via a jet nozzle and is melted there in the laser beam. By turning at the same time and shifting the coating lance result in spirally adjacent Caterpillars that have a coherent tread coating form. Due to the inherent beam parameter product (beam divergence and However, such devices are based on one beam relatively low length / diameter ratio of the coating lance limited so that they can be used to coat slim surfaces Cylinder bores or other component cavities that are difficult to access are unsuitable.
- the object of the invention is the coating device of the aforementioned Design in a structurally simple manner so that even those that are difficult to access Component inner surfaces, and in particular the lower surface sections of cylinder bores with a relatively small bore diameter, no problem and to be coated with high radiation efficiency.
- the laser light guide co-rotates with the coating lance and the laser radiation over an optical rotary coupling, but preferably directly from that on the device head arranged and also co-rotating laser source, in the device side Optical fiber end is coupled, the coating device is not on straight lance shapes is limited, but also others, Depending on the application, differently curved lance shapes can be used and there is a deflecting mirror at the tip of the lance for lateral beam deflection in a simple way that the light guide on the decoupling side End section is bent or an inclined to the light guide axis End face has, while in the second variant of the invention, at which the laser light guide in the coating lance by a non-rotatably arranged Optical fiber takes place, which is also in a rotationally fixed with the Device head connected inner tube of the coating lance exactly coaxial to the Axis of rotation of the coating lance is fixed, even then a further improved Energy transmission results when the laser source is removed from the device head is
- a is used as the laser source Diode laser provided, the inherently unfavorably high beam parameter product because of the superior transmission quality of the invention Coating device even with a very slim coating lance has no effect on the effectively applied laser power, which in the Other, however, much better performance values (socket efficiency) as a conventional solid, e.g. Nd: YAG laser has.
- the Process monitoring expediently facilitated by the fact that in the light guide from the tip of the lance opposite to the laser beam optical, e.g. the Infrared signals indicating the melting temperature at the respective coating location are fed back and decoupled for process control at the device head.
- the Process monitoring expediently facilitated by the fact that in the light guide from the tip of the lance opposite to the laser beam optical, e.g. the Infrared signals indicating the melting temperature at the respective coating location are fed back and decoupled for process control at the device head.
- the Infrared signals indicating the melting temperature at the respective coating location are fed back and de
- the coating device shown in FIG. 1 contains one as main components High-power diode laser 1, one of them optically via a light guide 2 coupled device head 3 and a coating lance 4, which on a Rotary guide 5 of the device head 3 mounted and by means of a drive motor 6 including a slip clutch 7 endlessly rotatable about a central axis A-A is driven.
- the light guide 2 runs through the device head 3 in a standpipe that is firmly connected to it and coaxial to axis A-A 8 continuously to the tip of the lance and is at the end of the standpipe by means of a Fiber connector 9 and one between this and the rotating outer tube 10 of the coating lance 4 effective ball bearings 11 exactly centrically attached to the axis of rotation A-A of the coating lance 4.
- a lance tube 10 which also co-rotates therewith interchangeable insert 12 with a collimation optics 13 and one Deflecting and focusing mirror 14 attached.
- the one from the fiber end divergent emerging laser beam is caused by the rotating around the light guide axis Collimation optics 13 converted into an axially parallel light beam and from the deflecting mirror 14 through a protective glass window 15 to the one to be coated Component inner surface 16, such as the cylinder surface of an engine block, redirected and focused.
- the coating device is completed by externally attached to the lance tube 10 Powder and gas feed lines 17, 18, through which the coating powder, such as a high-silicon aluminum powder and a protective gas on the focus region of the laser beam are blown out, and one in the outer tube 10 Compressed air duct 18 running from the device head 3 to the lance tip for generation one of the protective glass window 15 free blowing cross-jets and one Cooling water circuit for cooling the distal end of the light guide, which one coolant flow, in the area of the fiber connector in the annular space between Stand and lance pipe 8, 10 arranged cooling water jacket 20 and contains assigned flow and return channels 21, 22 in the lance tube 10 (Fig. 1b).
- the coating powder such as a high-silicon aluminum powder and a protective gas on the focus region of the laser beam are blown out
- Compressed air duct 18 running from the device head 3 to the lance tip for generation one of the protective glass window 15 free blowing cross-jets and one Cooling water circuit for cooling the distal end of the light guide, which one coolant
- temperature-indicating infrared signals from the coating site return in the opposite direction to the laser beam in the light guide 2 to the device head 3, where they go to a process control unit via a semi-transparent mirror element (not shown), for example for thermal process regulation of the coating process.
- the laser beam of the diode laser 101 is to the device head 103 via another, firmly connected to it
- the lance tube 110 In the area of the lance tip are the lance tube 110 and the light guide 102 bent so that the laser beam at the end of the light guide emitted obliquely to the axis of rotation A-A of the coating lance 104 and through a downstream, again interchangeable, collimation and focusing optics 24 is bundled onto the cylinder tread 116 without it this requires a deflecting mirror.
- the lance tube 110 can be in the bending direction be adjustable so as to adjust the deflection angle of the laser beam to be able to change. Incidentally, the construction and operation of this is Embodiment the same as in the coating device of FIG. 1st
- the laser light guide on the single beam side up to the diode laser is extended and this in the embodiment of FIG. 2 either co-rotating with the coating lance 104 or stationary with the device head 103 connected and the laser light guide 102 then via a rotary coupling the laser 101 is connected.
