Description
Technical field
The utility model belongs to a kind of laser head, particularly a kind of swing bifocus welding laser head.
Background technology
Laser weld is with its high energy density, good forming effect, advantage such as fast speed of welding and being used widely.Compare with vacuum electron beam welding, operate more simple, the needing no vacuum chamber, therefore the physical dimension to welded unit does not have strict requirement, the welding of the various attitudes in easy implementation space.So advantage that in the precision welding, has other welding method not have and match in excellence or beauty.In laser weld, common laser weld is to utilize single focus that welded unit is welded, and single focal argon laser welding is difficult on the technology grasp because light beam is very thin, and therefore, it has very high requirement to the assembly precision of welded unit.Adopting double focus laser to be welded on to a certain extent in recent years abroad addresses this problem.Because two focuses are arranged, heated perimeter can reach the effect that welding and heat treatment are carried out synchronously, but still certain limitation is arranged by bifocal apart from selection.
The utility model content
At the shortcoming that above-mentioned prior art exists, the long-pending experience of being engaged in this area work for many years of the inventor through feasibility study repeatedly, gets generation of the present utility model eventually; The utility model provides a kind of swing bifocus welding laser head.
The technical solution adopted in the utility model is: a kind of swing bifocus welding laser head, it is characterized in that: the laser exit that its connecting plate will weld laser head and laser instrument couples together, runing rest and connecting plate link together, and constitute the slip revolute pair with mounting flange, welding laser head housing and mounting flange are fixed together, and are the bodies that installs and fixes of laser beam splitter mirror bracket; Beam splitter is installed on the beam splitter carriage, and focus lamp and carriage thereof are installed on the laser head housing; The welding tip connector will highly finely tune fixed support and the laser head housing links together, and they are become one, welding tip with highly finely tune fixed support and link together, and can move up and down; Rolling bearing links together with swing bifocus amplitude adjusted plate, is fixed on together on the axle of electric rotating machine, and rolling bearing slides and is located at the sliding tray the inside, and sliding tray and laser head housing are fixed together.
Also be provided with cooling water water inlet tap and faucet in above-mentioned focus lamp carrier end.
Constitute height fine-adjustment by above-mentioned height fine setting fixed support and welding tip; Highly finely tune support bracket fastened in ring screw thread, it and welding tip are arranged is circumferentially to fix.
The utility model has increased the swing function to it on the basis that makes full use of the bifocus plumb joint.The swing application of bifocus technology in welding can overcome in the welding process on the one hand to the assembly precision of welded unit, significantly reduced the leading operation of welding, improved the efficient of welding, alleviated welder's labour intensity; On the other hand, it is passable also can to reach the effect of sufficient stirring welding pool.Therefore, the swing focus combines with bifocus, can improve the laser welding process performance greatly, and particularly the wire feed process for laser weld provides good technology ensuring, can reduce simultaneously the requirement of assembly precision, make it more obtain utilizing in the extensive fields.
The utility model has adopted the light path system of double focus laser technology, and on this basis and designed the special swing mechanism of a cover, make two focuses of laser weld in welding process, can form swing, laser welding process is improved significantly by above-mentioned design.It is mainly somewhat following:
1, can effectively adjust the weld heat input input density
2, increased the width of sweating heat input area, it can satisfy the needs of different size assembling
3, the stirring of welding pool is controlled
Compare with single focus, bifocus welding laser head can form two energy peaks and effectively improve heat affected area defective generation on section of weld joint
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the effect of the utility model swing bifocus welding laser head connecting plate 1 is that the laser exit that will weld laser head and laser instrument couples together.Runing rest 2 links together with connecting plate 1, and constitutes the slip revolute pair with mounting flange 3, and mounting flange 3 can rotate freely with respect to runing rest 2.Welding laser head housing 6 and mounting flange 3 are fixed together, and are the bodies that installs and fixes of laser beam splitter mirror bracket 4.Beam splitter 5 is installed on the beam splitter carriage 4, is divided into two bundles with penetrating the laser beam that comes.Focus lamp and carriage 7 thereof are installed on the laser head housing 6.Beam splitter 5 and focus lamp 11 can carry out angular adjustment with respect to laser head housing 6 respectively by beam splitter support 4 and focus lamp support 12.The effect of welding tip connector 15 is to link together with laser head housing 6 highly finely tuning fixed support 16, and they are become one.Welding tip 17 with highly finely tune fixed support 16 and link together, and can move up and down.Also be provided with cooling water water inlet tap 13 and faucet 14 in above-mentioned focus lamp carrier end.
The rotation of the electric rotating machine 7 of laser welding system drives the laser spot swing.Rolling bearing 9 links together with swing bifocus amplitude adjusted plate 8, is fixed on together on the axle of motor 7, and along with motor 7 together rotates, rolling bearing 9 is in sliding tray 10 slide inside, and sliding tray 10 is fixed together with laser head housing 6.
To the realization of bifocal oscillating motion be elaborated below.Runing rest 2 and mounting flange 3 constitute a pair of revolute pair, are to be free to rotate between them, also can be by locking device that they are locked.Whole housing can be with respect to the swing of part 1 do around vertical axes under the drive of motor 7 like this.Laser double focus is named a person for a particular job and do oscillating motion near weld seam.
Height fine-adjustment is by highly finely tuning fixed support 16 and welding tip 17 constitutes.The interior ring of highly finely tuning fixed support 16 has screw thread, and it and welding tip 17 are circumferentially fixing, but when rotation is highly finely tuned fixed support 16 like this welding tip 17 just in the vertical direction move up and down by screw thread, thereby carry out adjusting highly.
The above is preferred embodiment of the present utility model, and all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
