Machining positioning device for copper-iron-based powder metallurgy oil-retaining bearing

The utility model discloses a processing positioning device for a copper-iron based powder metallurgy oil bearing, which comprises a positioning mechanism, the positioning mechanism comprises a first rotating shaft, a fluted disc and a first electric push rod, the first rotating shaft is rotatably connected with the fluted disc through a first bearing, a brake motor is arranged below the first rotating shaft, and the first electric push rod is connected with the fluted disc through a second bearing. When the device is used, a first electric push rod drives a first pressing plate to be matched with a fluted disc to fix the oil bearing, meanwhile, a brake motor drives a gear to be rotationally matched with the fluted disc, the punching angle of the oil bearing is adjusted, and a second electric push rod drives a second pressing plate to be matched with a baffle to fix the fluted disc; the positioning stability of the oil-retaining bearing is improved, manual adjustment is not needed, the operation process is si
