As described above, the utility model provides an automatic change spoke production facility 10 can produce the aluminum alloy spoke idiosome that has inserts 100 to degree of automation is high. In addition, due to the insert 100, the machined aluminum alloy spoke blank body can be welded with a rim through the insert 100, and then the hub is further machined. In the hub production mode, the preparation of the spoke and the rim can be separately and independently carried out, so that the production efficiency is improved, and the total time of the production of a single hub is greatly reduced; meanwhile, since the spoke and the rim are not directly welded but welded together through the insert 100, the rim may be made of a material different from that of the spoke, for example, an iron alloy material, thereby reducing costs. Specifically, in the insert conveying device 40, the vibrating conveying mechanism 41 can arrange the unordered inserts 100 and convey the unordered inserts to the placing table 413 according to a predetermined orientation, and the insert moving mechanism 44 can grab the inserts 100 from the placing table 413 and cooperate with the pre-positioning mechanism 42 to place a plurality of inserts 100 one by one onto each insert station 422, so that the workpiece transfer device 50 can grab simultaneously. Meanwhile, the positioning detection mechanism 43 has a plurality of positioning sensors 432 arranged according to a predetermined rule, so that the grabbing condition of the workpiece transfer device 50 can be detected, and the condition that the insert 100 is missing in a product is avoided.

Further, the workpiece transfer device 50 can align the plurality of insert grippers 521 of the gripping mechanism 52 with the plurality of insert stations 422 of the pre-positioning mechanism 42, respectively, so as to simultaneously grip the plurality of inserts 100 placed on the plurality of insert stations 422, and simultaneously place the inserts 100 into the plurality of insert placement positions in the die of the die casting machine 62; after the die-casting of the spoke blank, the workpiece transfer device 50 can also clamp the material shank of the spoke blank by the clamping mechanism 53, so that the spoke blank is taken out of the die-casting machine 62 and transferred and placed on the conveyor belt 81 of the spoke conveying device 80.
