Description

Technical Field

[0001] The utility model relates to the technical field of carburetor processing, and particularly relates to an automatic assembly device for carburetor adjusting screws. Background Art

[0002] As an important component of traditional internal combustion engines, the performance of carburetors directly affects the working efficiency and fuel economy of engines. Carburetor screws, as key components for fixing and adjusting the internal structure of carburetors, the accuracy and efficiency of their assembly are crucial for the overall performance of carburetors. Existing carburetor screw assembly equipment usually fixes a drilling machine above a clamping station, and then fixes the carburetor housing on the clamping station, so that the holes on one side of the carburetor housing are located directly below the drilling machine for assembly. After the assembly is completed, the carburetor housing is flipped so that the holes to be assembled on the other side are located directly below the drilling machine, and the assembly continues. In this assembly method, for each side of the carburetor housing to be assembled, the carburetor housing needs to be refixed on the clamping station, which not only has low screw assembly efficiency but also increases the labor intensity of workers. Therefore, there is an urgent need for an automatic assembly device for carburetor adjusting screws to reduce the labor intensity of workers and improve the screw assembly efficiency.
