The invention discloses equipment for boring holes in a hinge beam of a six-side top hydraulic machine. The equipment comprises a baseplate and a base support fixed at the bottom of the baseplate, wherein a base is arranged at the top of the baseplate; a first center positioning ring is arranged on the base; a limiting hole is formed in the central position of the base; and a second center positioning ring is arranged in the limiting hole, and fixedly connected with the baseplate. The equipment is simple in structure and has the advantages that by adoption of the rotatable design, hinge beam earholes can be continuously machined, and the workpiece turnover difficulty and danger can be reduced; when working, a boring tool bar is fixed inside boring tool supports where self-lubricating bearings are built; in the boring process, each pair of the boring tool supports have very good stabilizing and supporting effects on the boring tool bar, thereby preventing the phenomenon that a boring tool vibrates in the boring process and guaranteeing the boring precision; not only that, a dynamic boring head and the boring tool bar are connected by adopting a universal coupling, thereby avoiding the strict positon demand; and accordingly, the equipment can be simplified, the working efficiency can be improved, and the equipment cost can be reduced.
