Description
Technical field:
The present invention relates to laser cladding apparatus, in particular to a kind of adjusting 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, by computer control laser head is relative with powder feeder, do building motion, 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 guarantee 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 CN 201826015U, 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 guarantee, it be the reasons are as follows: when carrying out laser alignment, regulate before calibration, by technique scheme, Cross Scale sheet is bonded on annulus pad, insert together in the lateral slot of centered cover, so operation, how to guarantee the concentric of Cross Scale sheet and annulus pad? how to guarantee the concentric of annulus pad and centered cover? if can not guarantee Cross Scale center and centered cover center superposition on Cross Scale sheet, so, when carrying out laser alignment adjusting calibration, just be difficult to judge whether centering of light beam, the adjusting calibration of also just not knowing where to begin to light beam.For the problems referred to above, the invention of Granted publication CN 201826015U does not disclose correlative detail.
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, the invention of Granted publication CN 201826015U is difficult to guarantee Cross Scale center and the centered cover center superposition on Cross Scale sheet, and then makes whole adjusting calibration program be difficult to guarantee the accuracy of calibration.
The invention provides following technical scheme: a kind of adjusting 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, the other end of described centered cover is provided with internal thread, described Cross Scale piece is provided with outside screw, and described Cross Scale piece can be threaded connection with in centered cover.Described centered cover inwall is provided with axial card article, one end of described card article is provided with limiting section, on described annulus pad periphery wall, offer the draw-in groove coordinating with described card article, the external diameter value of described annulus pad is same as the inner diameter values of centered cover, on described annulus pad, offer the circular groove concentric with annulus pad, the external diameter value of described Cross Scale sheet is same as the inner diameter values of described circular groove, and described Cross Scale sheet is arranged in described circular groove.
By technique scheme, before carrying out ruddiness centering adjusting calibration, in centered cover, only there is Cross Scale piece, so, carry out ruddiness centering and regulate while calibrating, red beam can directly be penetrated on Cross Scale piece, to judge whether ruddiness moves along the center of lens barrel, if ruddiness does not overlap with the Cross Scale true origin on Cross Scale piece, by adjusting mirror group, they are overlapped.
By technique scheme, before carrying out laser alignment adjusting calibration, from centered cover, take Cross Scale piece away, Cross Scale sheet is arranged in the circular groove on annulus pad, annulus pad is engaged and installed in centered cover by draw-in groove and card article, and limited portion is limited in predetermined position in centered cover, because the external diameter value of described annulus pad is same as the inner diameter values of centered cover, the external diameter value of described Cross Scale sheet is same as the inner diameter values of described circular groove, so, the present invention can guarantee Cross Scale center and the centered cover center superposition on Cross Scale sheet, and then improve the accuracy that whole laser melting coating regulates calibration.
As a further improvement on the present invention, described card article is four that along even circumferential, distribute, and described draw-in groove is four that along even circumferential, distribute.As further improvement, described Cross Scale sheet and Cross Scale piece are transparent.By above-mentioned improvement, before carrying out laser alignment adjusting calibration, the annulus pad that transparent Cross Scale sheet is installed is arranged in centered cover by card article and draw-in groove, and described transparent Cross Scale piece is threaded in centered cover, rotary cross scale piece, makes it press close to annulus pad.Due to Cross Scale sheet and Cross Scale piece all transparent, the Cross Scale of staff on can Cross Scale piece is that standard judges whether centering of Cross Scale sheet, if do not have, readjust the position of Cross Scale sheet on annulus pad, until the Cross Scale center on Cross Scale sheet and the Cross Scale center superposition on Cross Scale piece.So improve and can further improve the accuracy that whole laser melting coating regulates calibration.As to above-mentioned improved further improvement, on the sidewall of described centered cover, offer four screws that distribute along even circumferential, described screw is by described card article, and set screw has been threaded in described screw.So, if the Cross Scale center on Cross Scale sheet does not overlap with the Cross Scale center on Cross Scale piece, can readjust the position of Cross Scale sheet on annulus pad, and by set screw, annulus pad is radially finely tuned, Cross Scale sheet is radially finely tuned, until the Cross Scale center on Cross Scale sheet and the Cross Scale center superposition on Cross Scale piece.
As a further improvement on the present invention, the adjusting calibrating installation of described laser melting coating also comprises protection piece, and described protection piece is disk-shaped, and described protection piece is provided with outside screw, and described protection piece can be threaded connection with in centered cover, and described protection piece is provided with axially extending bore.Before carrying out laser alignment adjusting calibration, from centered cover, take off Cross Scale piece, change protection piece.When carrying out laser alignment adjusting calibration, laser may puncture Cross Scale sheet, has had protection piece, and laser will drop on protection piece, thereby avoids laser to wound the object of centered cover below.When carrying out laser alignment adjusting calibration, laser can cause that the temperature in centered cover rises, and on protection piece, offers through hole, not only facilitates auxiliary means to capture and protects piece and be arranged in centered cover, and have the effect of heat radiation.
As a further improvement on the present invention, described Cross Scale piece is provided with axially extending bore.On Cross Scale piece, offer through hole, to facilitate auxiliary means capture Cross Scale piece and be arranged in centered cover.
