Description
Technical field
The utility model relates to a kind of cladding machine, especially a kind of laser melting coating machine.
Background technology
Laser melting and coating technique refers to places the coated material of selecting on coated matrix surface in different filler modes, through laser irradiation, make it to melt with matrix surface skim simultaneously, and it is extremely low and become the top coat of metallurgical binding with body material to form extent of dilution after rapid solidification, thereby significantly improve the processing method of wear-resisting, anti-corrosion, heat-resisting, the anti-oxidant and opering characteristic of electric apparatus etc. of substrate material surface.
Equipment for laser melting and coating technique is mainly laser melting coating machine, selects CO2 or solid statelaser, is mainly used in non-ferrous alloy surface modification.By the difference of powder feeding technique, can be divided into the preset method of powder and synchronous powder feeding system method, synchronous powder feeding system method has and easily realizes automatization and control, laser energy absorption rate is high, without internal porosity, especially deposited metals is ceramic, can significantly improve the anti-cracking performance of cladding layer, make the advantages such as hard ceramic can be uniformly distributed mutually in cladding layer.
Existing laser melting coating machine has belonged to mature technology, as shown in Figure 1, mainly comprise fuselage 1, be positioned at the Laser Power Devices 2 of fuselage 1, be positioned at the three-dimensional working platform 3 on fuselage 1, and be positioned at the laser apparatus 4 on three-dimensional working platform 3, this laser apparatus 4 includes the housing 41 being installed on three-dimensional working platform 3, in this housing 41, be provided with reaction chamber 411, in this reaction chamber 411, laser generating system 42 is installed, reaction chamber 411 wall places, chamber offer the laser channeling 43 extending to outside reaction chamber 411, the opening part of laser channeling 43 is provided with the focusing system 44 cooperatively interacting with laser generating system 42.Laser generating system 42 is by Laser Power Devices 2 energy supplies and produce light beam, and the light beam producing is focused on and exported by focusing system 44 after laser channeling 43, and now the laser beam of output is concentrated, energy is high, can fast and effeciently realize the cladding of workpiece surface.Wherein, laser apparatus 4 is fixedly mounted on three-dimensional working platform 3, the direction of institute's Emission Lasers light beam can only be adjusted by three-dimensional working platform 3, and institute's energy setting range is less, and can only be at the enterprising line operate of horizontal plane, in the time of most of, can only meet cladding needs by adjusting the putting position of workpiece, particularly, for large-scale workpiece or fixation workpiece, just be difficult to meet the needs of cladding.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of laser melting coating operation of improving, and meets the laser melting coating machine of large-scale workpiece or fixation workpiece cladding by self laser beam angle adjustment.
The utility model solves the technical scheme that its technical problem adopts: a kind of laser melting coating machine, comprise fuselage, be positioned at the three-dimensional working platform on fuselage and be positioned at the laser apparatus on three-dimensional working platform, this laser apparatus includes the housing being installed on three-dimensional working platform, in this housing, be provided with reaction chamber, in this reaction chamber, laser generating system is installed, wall place, reaction chamber chamber offers the laser channeling extending to outside reaction chamber, the opening part of laser channeling is provided with the focusing system cooperatively interacting with laser generating system, described housing is cylindrical structure, also includes:
Rotary seat, is fixedly installed on three-dimensional working platform, offers the through hole wearing for housing on this rotary seat, offers some roller slots around through hole axial distribution on the inwall of this through hole, and the length direction of each roller slot is axially consistent with through hole;
Roller, is rollably installed in roller slot;
Limited cover, is fixed on rotary seat by fastening piece, and is positioned at the aperture position of through hole;
Position corresponding with via openings position on described housing is provided with stopper slot, and the edge of limited cover is inserted in stopper slot.
The beneficial effects of the utility model are: because laser apparatus is installed on rotary seat, and the housing of laser apparatus can freely rotate in the through hole on rotary seat, therefore, focusing system on housing by along with rotation, change laser beam transmit direction, for large-scale workpiece or fixation workpiece, only need to coordinate three-dimensional working platform, and the sense of rotation of housing, just can carry out laser melting coating operation to the surface of large-scale workpiece or fixation workpiece.As for housing shaft to fixing, by the cooperation of limited cover edge and stopper slot; The particularly circumferential rotation of housing, only need to guarantee that the width of stopper slot is corresponding with the degree of depth that limited cover edge inserts, and just can realize circumferential spacing of housing, specifically adopts which kind of form, completely can be by client need to carry out free setting.By the way, can guarantee that the laser beam angle that laser apparatus is launched realizes multi-angle without the adjustment at dead angle, and can avoid that large-scale workpiece or fixation workpiece carrying etc. bring loaded down with trivial details, make its applicable more occasions, range of application is more extensive.
In order to make progress outside moving-limiting in housing shaft, after also guaranteeing upwards to rotate in housing week, can limit to greatest extent it is rotated further at every turn, so stopper slot is ring structure, this stopper slot is axial arranged around housing, the bottom land position of stopper slot offers some locating notches, each locating notch is uniformly distributed along the stopper slot of ring structure, and the marginal position of described limited cover convexes with the positioning pin matching with locating notch.
For guarantee laser apparatus after self axial rotation can and rotary seat maintenance relative static, and each postrotational angle can be more accurate, so the arc length between any two adjacent locating notches is 1/90th of housing circumferential length.Also, when positioning pin moves to adjacent positioned breach from a locating notch, the angle that housing rotates is 4 °, and this angle can meet the needs of positioning accurate accuracy to greatest extent.
Because the rolling resistance between roller and housing, after permanent, still can cause wearing and tearing to each other, thereby the tolerance range of impact location, so be coated with graphite linings on through-hole wall, this graphite linings is filled the gap between full through-hole wall and housing outer wall, by graphite linings, can not only lubricate contact between the two, and can be when wearing and tearing appear in surface in contact, fill up in time the breach of wearing and tearing, guarantee to greatest extent the precision of location.
In order further to improve the lubricating effect of graphite linings, particularly after graphite linings loss, can keep contacting between housing and through-hole wall, so be mingled with ball in graphite linings, ball can not disappear because of the loss of graphite linings, therefore can remain cooperation between the two by ball.
