The specific embodiment

Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.

Referring to Fig. 1-Fig. 5, a kind of water pump vane weld jig of the present utility model is made up of die holder, hold down gag (interior gland or pressing plate), clamp nut 8, focusing plate 9, outer gland 10, pedestal 11.Wherein, die holder is made up of mandrel 6, base 1, backing plate 3, template 4, alignment pin I 2, alignment pin II 5, alignment pin III 12, alignment pin II 5 is fixed on the base 1, base 1, backing plate 3, template 4 connect by alignment pin I 2, alignment pin III 12,2 splines are arranged on base 1 centre bore, the accurate matched in clearance of key on groove and the mandrel 6, the other key on another groove and the mandrel 6 is matched in clearance greatly.

When the utility model uses, adorn two width of cloth water pump vane weld jigs, a pair is used to weld impeller A end face A, and a pair is used to weld impeller B end face B, enforcement of the present utility model is done explaining below.

This two sub-folders tool all need assemble before clamping impeller 13, and assemble sequence is roughly followed the end of from the principle to the top, and the concrete operations mode is:

For being used to weld impeller A end face anchor clamps, earlier alignment pin II 5 (2 kinds each 6 of length) is a tight fit on the base 1 (according to impeller 13 structures, long alignment pin is contained on the inner ring hole, short alignment pin is contained on the cycle hole), use alignment pin I 2 again, alignment pin III 12 is successively base 1, backing plate 3, template 4 couples together, connecting sunk screw locking with 3 is integral, 2 splines are arranged on base 1 centre bore, the accurate matched in clearance of key on groove and the mandrel 6, the big matched in clearance of other key on another groove and the mandrel 6, because the centre bore keyway of impeller 13 has 8, impeller blade has only 6, the not corresponding distribution of both one-tenth, so the effect of 2 keys on the mandrel 6 is key location, another key is for after having welded the impeller A end face, place impeller in conjunction with the weldering trace as reference when welding impeller B end face again, so that welding track does not walk, what reduce to programme is loaded down with trivial details, mandrel 6 installs to back, position and base 1, backing plate 3, template 4, alignment pin I 2, alignment pin III 13 grades together, abbreviate die holder as, again die holder is contained on the centre bore of pedestal 11 centres, also have a rotary freedom by the bar hole constraint of alignment pin III 12 with pedestal 11, die holder has just had only the axial displacement free degree of a mandrel 6 like this.

For being used to weld impeller B end face anchor clamps, use alignment pin I2, alignment pin III 12 is successively base 1, backing plate 3, template 4 couples together, be integral with 3 attachment screw lockings, also there are 2 on base 1 centre bore with the same spline of mandrel 6, effect is with noted earlier, mandrel 6 installs to back, position and base 1, backing plate 3, template 4, alignment pin I 2, alignment pin III 12 grades together, abbreviate die holder as, again die holder is contained on the centre bore of pedestal 11 centres, since be used to weld impeller A end face anchor clamps and adopt same pedestal 11, so die holder has also had only the axial displacement free degree of a mandrel 6.

After two sub-folder tools assemble, must be installed in pedestal respectively on 2 identical rotary tables with 6 six interior angle cheese head screws, the anchor clamps of this 2 station can exchange certainly, but welding procedure is different, is the installation way of 2 sub-folder tools below:

At first an end of 1 blade of impeller 13 is set in the locating slot of template 4 of die holder the inside, the other end is embedded in length, between the short alignment pin II 5, just be fixed up in the position of blade like this, all the other 5 fixing successively in the same way, again the A end face of impeller 13 is put into by shown in Figure 1 along mandrel 6 after intact, then put into outer gland 10, a gap of outer gland 10 exterior rim will be stuck on the pin of backing plate 3 cylindricals, the initial weld in 6 places of blade is just being dropped in the middle of the corresponding 6 place's breach of inside rim of outer gland 10, load onto lock-screw, allow the outward flange of outer gland 10 compress the outer circumferential edge edge of A end face, gland 7 and clamp nut 8 in loading onto at last, fastening nut compresses the internal circle edge of A end face, and the little distortion integral body of blade is adjacent to the impeller A end face.Welding for the first time also need be loaded onto focusing plate 9, mix up the focal spot size and the track of laser, lay down focusing plate 9 again, welding later on can be adorned focusing plate 9, and start program moves out of laser weld, unclamps screw and clamp nut 8 on the outer gland 10 after having welded in order, gland 7 and outer gland 10 in taking out, take out workpiece again, the A end face welding of impeller finishes, and changes down the secondary welding of operation over to.

The impeller of the welding of last operation put into be used to weld in the die holder of impeller B end face anchor clamps, note snapping in the keyway position of 2 keys, the impeller B end face of packing into, load outer gland 10, clamp nut 8, pressing plate 15, locking nut more successively, method and last operation are basic identical, and working procedure goes out laser weld, unload lock jack panel, clamp nut 8, pressing plate 15, outer gland 10 successively after having welded, take out impeller 13, so far a complete impeller 13 is finished by twice welding.

Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give exhaustive to all embodiments.Everyly belong to the row that conspicuous variation that the technical solution of the utility model extends out or change still are in protection domain of the present utility model.
