Realize automation.Especially in refractory material, thin-sheet metal welding field laser welding is even more to show incomparable superiority.
Based on these advantages, laser welding water pump vane is considered as one of most promising advanced connected mode.
Laser welding impeller needs with front shroud and back shroud to fix blade by fixture respectively, is then welded,
Existing fixture has the following problems：（1）It is manual fixture mostly, automaticity is not high；（2）Clamping is with changing frock smelting
Tool needs the time, and so, the process of laser welding will be interrupted；（3）The structure not positioned, only by being carried out to impeller periphery
The mode of compression realizes fixation, in welding process, it is possible to can shift and cause the inaccurate of welding position, so that
Make the repair rate and disqualification rate of impeller higher.

Embodiment
Below in conjunction with the accompanying drawings and embodiment, the present invention can be better described.
A kind of impeller fixture for laser welding, including the first turntable 1, the lower section of the first turntable 1 are provided with revolution dress
2 are put, first turntable 1 is provided with the impeller clamping device for being provided with least two, the impeller clamping device and first
The axle center that turntable 1 rotates is placed equidistant, and the impeller clamping device includes support plate 3, the jig being located in support plate 3
4 and at least two hold down assembly 5, and described hold down assembly 4 is placed equidistant with jig 5, described to hold down assembly 4 by air pressure
Or hydraulic-driven.The effect of double or multistation cooperation is realized, an impeller clamping device is in laser welding, Qi Taye
Wheel clamping device is used for changing workpiece, improves equipment work limitation and reduces clamping with changing the time of frock smelting tool, by using
Double or multistation, which can be improved preferably, realizes equipment work limitation；Hold down assembly by air pressure or hydraulic-driven, it is real
Now automation is clamped；Shaft hole matching in the middle of jig and impeller, realizes the positioning of impeller.
5 cylinders for including cylinder installed part 501, being set up vertically in cylinder installed part 501 that hold down assembly
502nd, in cylinder 502 Rocker arm 5 04 that cylinder push-rod 503 and cylinder push-rod is hinged, the Rocker arm 5 04 is installed with cylinder
Part 501 is hinged.Cylinder push-rod 503 is set to push up one end of Rocker arm 5 04 by air pressure, the other end of rocking arm is with regard to downward pressing clip
Tool, compressing fixture can also be driven directly down by way of air pressure or hydraulic pressure, but the pressure difference that this mode drives is big
Air pressure subtracts internal pressure, and pressure is unable to reach higher, and sets rocking arm by the force direction of driving from being changed into upward downwards, pressure difference is
Internal pressure subtracts atmospheric pressure, and pressure can be higher, and more reliable.
Silicagel pad 505 is provided with below the end of the Rocker arm 5 04.Increasing friction force is played, prevents impeller in laser welding
During skid or due to caused by deformation loosen.
The support plate 3 be provided with slide rail 301, it is described hold down assembly 5 lower section be provided with sliding block 506, it is described hold down assembly 5 with
Sliding block 506 is located above and below slide rail 301 and is connected by screw respectively, and 5 are held down assembly with sliding by the way that screw is adjustable
The distance between block 506.5 are held down assembly the distance between with sliding block 506 by screw regulation, allow to hold down assembly 5 relative
Guide rail is slid and locked, and the impeller of different-diameter specification can be coordinated by adjusting the position held down assembly between 5 and jig 5
Welding, it is possible to achieve without going frequently to change fixture by workpiece, frock can follow workpiece face shaping practicable automatic
Or manually adjust；Reduce operating personnel and equipment effective time.
Described hold down assembly 5 is connected with cylinder slide component 6, can be driven by cylinder described in hold down assembly and 5 slidings and lock
Tightly.Adjust automatically is realized, automaticity is higher.
The support plate 3 is connected with rotating servo motor 7.The blade of impeller is shaped form, and rotation is set below support plate 3
Turn servomotor, rotate its impeller, rotary speed is controlled, as long as the laser of welding is moved from inside to outside, it is possible to
Welded along the curve of blade, so requirement to the laser displacement of welding is exactly that vertically, can also make impeller
Motionless, curve displacement of the laser along blade completes welding.
The slewing equipment 2 is Cam splitter.Cam splitter is the mechanism for realizing intermittent movement, with indexing accuracy
Self-locking, compact conformation, small volume, low, the good, long lifespan of high speed performance of noise etc. when height, smooth running, big transmission moment of torsion, positioning
Distinguishing feature.
The lower section of first turntable 1 is provided with secondary positioner 8, and the secondary positioner 8 is that cylinder and cylinder are pushed away
Bar, first turntable 1 is provided with the jack being adapted to cylinder push-rod.One-time positioning can be realized in Cam splitter rotation
Stop, but the weight above the first turntable is larger, rotates the inertia formed also than larger, sets secondary positioner 8, when
When first turntable rotates to correspondence position, in drive cylinder push rod insertion jack, positioning can be made relatively reliable.
It is described to hold down assembly 53 and to be placed equidistant.Three points of 35 formation equilateral triangles that hold down assembly, can be with
Impeller is securely fixed, further, since the quality of impeller in itself is just weighed very much, revolution can be reduced by only setting 3 to hold down assembly
Device 2 drives the heavy burden that the first turntable 1 is rotated.
The periphery of support plate 3 is nearly equilateral triangle structure, and the slide rail 301 is located on central point to the straight line of angle point,
The support plate 3 is provided with the through hole of some triangles.So subtract as far as possible on the premise of the weight capacity of support plate 3 is ensured
The weight of small support plate 3, reduces the heavy burden that slewing equipment 2 drives the first turntable 1 to rotate.
A kind of embodiment of the present invention is the foregoing is only, not for limiting the scope of the invention；The present invention's
Protection domain is limited by the claim in claims, and every equivalence changes made according to invention and modification, is all existed
Within the protection domain of patent of the present invention.
