Description
Technical field:
The present invention relates to laser cladding apparatus, in particular to a kind of calibrating installation of laser melting coating.
Background technology:
Laser melting coating is mainly used in fine coatings cladding, the three-dimensional manufacture fast of machine parts'precise etc., in laser cladding process, laser beam irradiation also focuses on cladding matrix finished surface, powder feeder is sent into metal-powder in the laser beam focusing hot spot on cladding matrix finished surface, do building motion by computer control laser head is relative with powder feeder, the powder smelting that mobile laser beam is sent into servo-actuated powder feeder in different claddings position and constantly form new molten bath, powder rapid melting rapid solidification, thus realize accurate cladding forming.In this dynamic process, in order to ensure good complete processing, must adopt the light source of high-quality, as laser, but light beam is after through one group of filter, very likely can depart from central position, thereby has affected the processing effect of laser melting coating.To this, Granted publication CN201826015U, the disclosure of the invention in May 11 2011 Granted publication day a kind of alignment device for laser melting coating, comprise a centered cover, Cross Scale piece, annulus pad and Cross Scale sheet, described centered cover is the column structure of inner hollow, the upper and lower two ends of described centered cover are respectively equipped with outside screw and internal thread, and described centered cover bottom coordinates and offers lateral slot with described annulus pad.This invention is by utilizing centered cover to be connected with laser melting coating mirror group, and centered cover is combined with Cross Scale piece and Cross Scale sheet, observes light beam and judges light beam centering situation with the situation that overlaps of true origin on Cross Scale piece and Cross Scale sheet.
Although can carrying out centering to light beam easily, technique scheme regulates calibration, but, the accuracy of its calibration is but difficult to ensure, it be the reasons are as follows: described centered cover is threaded with laser melting coating lens barrel, described Cross Scale piece is threaded with centered cover, two places the produced error that is threaded is difficult to ensure that laser melting coating lens barrel is concentric with Cross Scale piece, and the calibration of doing under the concentric prerequisite that is difficult to ensure of laser melting coating lens barrel and Cross Scale piece is inaccurate, and deviation is larger in other words.
Summary of the invention:
Technical problem solved by the invention: before carrying out laser melting coating, light beam is carried out to centering and regulate calibration, adjusting calibration program of the prior art is difficult to ensure the accuracy of calibration.
The invention provides following technical scheme: a kind of calibrating installation of laser melting coating; comprise centered cover, Cross Scale piece, annulus pad, Cross Scale sheet; one end of described centered cover is provided with outside screw; described Cross Scale sheet sticks on annulus pad; described annulus pad is arranged in centered cover; described Cross Scale piece and centered cover one, described Cross Scale piece is positioned at the other end of centered cover, and the top of described Cross Scale piece is provided with protection piece.
By technique scheme, Cross Scale piece and centered cover one, to eliminate in prior art the Cross Scale piece error being produced that is threaded with centered cover, to reduce the concentric deviation between laser melting coating lens barrel and Cross Scale piece, and then the accuracy of raising light beam to alignment.Because Cross Scale piece is fixed on centered cover; can not take off; when regulate calibration with laser; laser may puncture Cross Scale sheet and drop on Cross Scale piece; Cross Scale piece is sustained damage; to this, the present invention arranges protection piece above Cross Scale piece, to prevent that laser from wounding Cross Scale piece.
As further restriction of the present invention, described centered cover is provided with internal thread, and described protection piece is disk-shaped, and described protection piece is provided with outside screw, and described protection piece is threaded in centered cover, and described protection piece is provided with axially extending bore.Wherein, axially extending bore, as a handgrip of auxiliary means, screws protection piece in centered cover with this.
As a further improvement on the present invention, described Cross Scale piece is transparent.As described in the invention of Granted publication CN201826015U, laser melting coating regulates calibration first to carry out with ruddiness, and Cross Scale piece is set to transparently observe the position of red beam on Cross Scale piece with handled easily personnel herein.
As a further improvement on the present invention, described annulus pad is provided with outside screw, and described annulus pad is threaded in centered cover, and described annulus pad is provided with axially extending bore.As described in the invention of Granted publication CN201826015U, whole laser melting coating regulates calibration first to use ruddiness, then uses laser.In the time carrying out ruddiness centering adjusting calibration, annulus pad is screwed out centered cover by the axially extending bore that utilizes auxiliary means crawl annulus pad to be provided with, the axially extending bore that utilizes auxiliary means to capture on protection piece will protect piece to screw out centered cover, so, red beam can directly be penetrated on Cross Scale piece, to judge the centering situation of red beam; In the time carrying out laser alignment adjusting calibration; the axially extending bore that utilizes auxiliary means to capture on protection piece will protect piece first to screw in centered cover; the annulus pad that is pasted with Cross Scale sheet is screwed in centered cover by the axially extending bore that recycling auxiliary means captures on annulus pad; so; even if laser punctures Cross Scale sheet; laser can drop on protection piece, and can not damage Cross Scale piece.
As a further improvement on the present invention, described Cross Scale sheet is transparent.In the time carrying out laser alignment adjusting calibration, first, the annulus pad that is pasted with transparent Cross Scale sheet is screwed in centered cover by the axially extending bore that utilizes auxiliary means to capture on annulus pad, annulus pad is continuous and Cross Scale piece is approaching until fit together, now, operator's observable stick on Cross Scale center on the Cross Scale sheet on annulus pad whether with Cross Scale piece on Cross Scale center superposition, judge with this whether Cross Scale sheet sticks on annulus pad exactly.If Cross Scale sheet does not stick on annulus pad exactly, operator can regulate.After ensureing that Cross Scale sheet sticks on annulus pad exactly, annulus pad is screwed out to centered cover, then will protect piece to screw in centered cover, then annulus pad screw-in centered cover is carried out to laser alignment adjusting calibration.By above-mentioned improvement, regulate and in calibration, increased the adjusting of Cross Scale sheet and Cross Scale piece calibration at laser melting coating, so can improve the accuracy of whole laser melting coating adjusting calibration.
