The invention relates to the technical field of quick coupling assembling equipment, in particular to a sleeve assembly feeding and assembling device of a quick coupling assembling machine. The sleeve assembly feeding and assembling device comprises a sleeve feeding station and a spring feeding station, wherein the sleeve feeding station comprises a vertical pneumatic sliding table, a horizontal pneumatic sliding table, a pneumatic clamping jaw and a sleeve feeding seat. The pneumatic clamping jaw is mounted on the vertical pneumatic sliding table which is mounted on the horizontal pneumatic sliding table. The spring feeding station comprises the vertical pneumatic sliding table, a spring feeding sleeve and a quantitative spring feeding device, and the spring feeding sleeve is mounted on the vertical pneumatic sliding table and arranged above a bolt. According to the sleeve assembly feeding and assembling device, the independent sleeve feeding station and the independent spring feeding station are used for independently assembling sleeves and sleeve springs in the quick coupling assembling process, a sleeve assembly obtained after assembling is assembled with a center assembly, and the problem that the mounting difficulty of the sleeve springs is high is solved.
