The invention discloses a hoisting, positioning and lubricating structure of a reciprocating pump high-precision rack hole machining boring rod, and relates to the field of petroleum engineering equipment. The hoisting, positioning and lubricating structure specifically comprises a lifting appliance, a boring rod, a copper sleeve part, a rack, a rack hole machining clamp, a cavity between an end cover and a copper sleeve, a lifting hole, an outer circle, a positioning outer circle, an oil inlet channel, an oil return channel, a friction inner hole, various copper sleeve part positioning and mounting holes and a copper sleeve part positioning and mounting hole gland. By adopting the hoisting, positioning and lubricating structure of the reciprocating pump high-precision rack hole machining boring rod, when the high-precision rack hole is machined, the boring rod and a copper bush part on the boring rod can be horizontally hoisted, so that the hoisting time for replacing the position of a machining hole is shortened easily through a compact hole space of a rack structure; the copper sleeve part is convenient to position and high in positioning precision, and the accurate position of the boring rod is guaranteed; and the outer circle of the boring rod and the friction inner hole of the copper sleeve part as a friction pair are fully lubricated, so that the service life of the friction pair can be prolonged.
