The invention provides assembling equipment for a built-in soldering lug of a two-way joint, and belongs to the technical field of metal part machining. A base feeding mechanism, a visual grabbing mechanism, a direction adjusting mechanism, an automatic base discharging mechanism, a copper ring piece machining mechanism, a bamboo joint piece placing mechanism, an assembling and pressing mechanism and an automatic discharging mechanism are sequentially arranged beside a rotary disc. Automatic feeding operation of a base and automatic adjustment of the direction of a welding hole in the base are achieved, automatic machining and installation of a copper ring piece can be achieved at the same time, the problem that machining, transferring and manual placing are needed in advance is solved, the workload is relieved, automatic feeding of a bamboo joint piece can be achieved, the base and the bamboo joint piece are automatically and temporarily fixed, automatic discharging is conducted on the base and the bamboo joint piece which are temporarily fixed, the automation degree is higher, the machining efficiency is improved, potential safety hazards caused by manual operation are avoided, and industrialization machining of the two-way joint is facilitated.
