Background

With the more and more extensive application of the centrifugal fan of the air conditioner, the centrifugal fan is applied to refrigeration equipment, purification and dust removal equipment, and in recent years, kitchen oil fume exhaust equipment is also widely applied, so that the demand for the centrifugal fan of the air conditioner is increased, and the processing efficiency needs to be improved. Because the impeller of the centrifugal fan of the air conditioner has high rotating speed, the used material is thick, and the centrifugal fan has the characteristics of high pressure, high rotating speed and the like, most manufacturers adopt a welding structure, namely the blades are connected with the middle disc, and the front disc is connected together by adopting a welding process. Although the structure has high manufacturing strength, the production efficiency is low, the welding is easy to deform, the technical requirement on the operation of welding workers is high, and a plurality of welding inferior-quality products exist.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defect that prior art exists, provide an air conditioner centrifugal fan impeller that adopts to insert the mode equipment of riveting.

In order to realize the purpose, the utility model discloses a technical scheme as follows:

the utility model provides an air conditioner centrifugal fan impeller, includes front bezel, well dish and sets up a plurality of blades between front bezel and well dish, the both ends of blade have respectively and insert the claw down, be equipped with on front bezel, the well dish with insert the jack that the claw corresponds, insert the jack that the claw corresponds down, insert in the jack of front bezel is inserted to the last claw of inserting of blade one end, on insert the claw and rivet with the front bezel, insert the claw under the blade other end and insert in the jack of well dish, insert claw and well dish riveting down.

Further, a plurality of blades between the front disc and the middle disc are arranged in an annular mode at equal intervals.

Furthermore, the number of the upper inserting claws and the lower inserting claws is multiple, and the upper inserting claws and the lower inserting claws are integrally formed with the blade.

Furthermore, after the blades are inserted and riveted with the front disc and the middle disc, two ends of the blades are in close contact with the inner side surfaces of the front disc and the middle disc.

Further, the front disc is of a circular arc structure.

The utility model has the advantages that: the two ends of the blade of the fan impeller are respectively provided with an upper inserting claw and a lower inserting claw, the front disc and the middle disc are provided with insertion holes corresponding to the upper inserting claw and the lower inserting claw, the upper inserting claw at one end of the blade is inserted into the insertion hole of the front disc, the upper inserting claw is riveted with the front disc, the lower inserting claw at the other end of the blade is inserted into the insertion hole of the middle disc, the lower inserting claw is riveted with the middle disc, the upper inserting claw, the lower inserting claw and the insertion holes are matched to conveniently and accurately position the blade between the front disc and the middle disc, the upper inserting claw is riveted with the front disc, the lower inserting claw is riveted with the middle disc to firmly fix the blade between the front disc and the middle disc, in addition, the front disc of the centrifugal fan of the air conditioner is of an arc structure, and the blade. The impeller replaces the traditional welding and fixing mode of the blades by the inserting and riveting mode, so that the production efficiency is greatly improved, the blades are accurately positioned, the mass production can be realized, the mold production of the impeller can be realized, the manufacturability is improved, and the strength of the impeller can be comparable to that of a welded impeller through an impeller overspeed test; the manufacturing process is simple, and the cost performance is greatly improved; the structure is compact.
