The utility model relates to the technical field of code spraying machines, and discloses a drum type
brake pad code spraying device which comprises a
machining table, a rotating shaft is rotatably installed in the middle of the interior of the
machining table in the vertical direction, a stepping motor is fixedly installed at the bottom of the
machining table, and the output end of the stepping motor is fixedly installed at the bottom of the rotating shaft. And a rotating table is fixedly mounted at the top of the rotating shaft. Due to the arrangement of the stepping motor, the air blowing
assembly, the protruding block and the like, when the stepping motor drives the
brake pad placed above the rotating table to rotate to the side close to the protruding block, the protruding block extrudes the
piston rod to move, and a movable clamping block at the top of a connecting block on the
piston rod moves towards one side of the
brake pad; and meanwhile, a
piston rod extrudes air in a piston
barrel, so that the air is blown out from one end of an air blowing
pipe, sweeps, dust and the like on the surface of the
brake pad are blown off, and the code spraying quality is improved.
