Embodiment Construction

[0018] Such as figure 2 As shown, the shell of the harvester re-extractor includes a volute 13, an end cover 11 welded on one side of the volute 13, and a flange 14 welded on the other side of the volute 13. The shape of the volute 13 is not It is completely cylindrical and forms the interface of the grain output tube connected with the grain output tube of the harvester. The two edges of the outer curved surface of the volute 13 are bent outward to form two connecting plates 17 for connecting with the grain output tube. Each connecting plate 17 is provided with Two threaded holes 16. The shape of the end cover 11 is disc-shaped, and an opening is opened on the top surface of the end cover 11 , and a flange 18 facing the volute 13 is also provided at the opening.

[0019] Such as figure 1 As shown, the assembly tooling of the harvester re-extractor shell of the present invention is used to assemble the volute 13, end cover 11 and flange 14 of the re-extractor shell into one...

Abstract

The invention discloses an assembly tool for a rethresher shell of a harvester. The assembly tool is used for integrally assembling a spiral case, an end cover and a flange of the rethresher shell, and comprises a pedestal, a spiral case positioning part, an end cover positioning part and a flange positioning part, wherein the spiral case positioning part is in positioning connection with the spiral case; the end cover positioning part is in positioning connection with the end cover; the flange positioning part is in positioning connection with the flange; and the spiral case positioning part, the end cover positioning part and the flange positioning part are arranged on the pedestal. By adopting the technical scheme, the accurate positioning of each part is realized when the rethresher shell is assembled; assembly efficiency is increased; the assembly tool is easy to operate and is time-saving and labor-saving; each part can be prevented from being deformed during assembly; assembly errors are reduced; and the rethresher shell has higher dimensional accuracy after being assembled.

Description

technical field [0001] The invention relates to auxiliary equipment for the manufacture of a harvester, in particular to a tool for assembling the shell of a re-extractor of a harvester. Background technique [0002] The re-extractor of the harvester is one of the main accessories of the harvester. The re-extractor of the harvester is connected with the grain output cylinder of the harvester. The shell of the re-extractor is a cylindrical volute with an end cover on one side of the volute. , a flange is provided on the plane on the other side, and two connection plates are symmetrically provided on the curved surface of the volute, and the re-extractor is tightly connected with the harvester grain output cylinder through the connection plates. At present, the assembly of the shell of the re-extractor of the harvester is purely manual operation by the production personnel, and the end cover, the flange and the volute are respectively welded and connected into one body, becaus...
