The invention discloses intelligent fixing equipment for pipeline machining. The intelligent fixing equipment comprises a device seat. The upper end of the device seat is movably connected with a basethrough a plurality of sliding rails, and a honing roll is arranged at the upper end of the base. A fixing groove is formed in the device seat, and a connecting shaft is movably connected into the fixing groove. Symmetrically-distributed rotating discs are arranged on the connecting shaft, and a plurality of evenly-distributed honing grooves are formed between the rotating discs. Pipeline fixingblocks are arranged in the honing grooves, and a plurality of evenly-distributed clamping grooves are formed in the pipeline fixing blocks. A feeding groove is formed in one side of the fixing groove,and a positioning block is arranged in the feeding groove and is aligned at the corresponding honing groove in the fixing groove. Positioning grooves which are matched with the clamping grooves in number and shape are formed in the positioning block. A sixth electric hydraulic adjuster is arranged on the outer side of the feeding groove and connected with a push plate through a sixth hydraulic rod. The intelligent fixing equipment is easy to operate, high in comprehensive practicability and easy to use and popularize.
