8. A method for removing burrs of a spatial phase through hole structural part comprises the following steps:
step one, inserting a polish rod of a main cutter bar (1) into a hole corresponding to a spatial phase through hole structural component 5 to be deburred, and ensuring that the lower bottom surface of the main cutter bar passes through an inner hole opening;
inserting the lower part of an inner support rod (2) provided with a blade (3) into a cylindrical blind hole (16) in a main cutter bar (1), ensuring that the orientation of a handle (22) of the inner support rod is consistent with that of a handle (12) of the main cutter bar, pressing down the handle (22) of the inner support rod until the handle (22) of the inner support rod is embedded into an opening groove (17) at the top of the main cutter bar (1), and enabling the blade to extend out of a cylinder (11) of the main cutter bar (1) from a plurality of rectangular through grooves (15) below the main cutter bar;
step three, the spatial through hole structural part is fixed, the inner stay bar handle (22) and the main cutter bar handle (12) which are pressed together are lifted out of a corresponding hole of the spatial through hole structural part (5) together, so that the blade (3) contacts the edge of the orifice of the through hole, and the burr of the orifice of the through hole can be removed by repeatedly rotating clockwise and anticlockwise for 2-4 times at a rotation angle of more than 90 degrees;
and step four, after the step is completed, fixing the cylinder (11) of the main cutter bar (1) by the left hand, slightly lifting the inner support rod handle (22) by the right hand to lift the blade to be retracted into the cylinder (11) of the main cutter bar (1), and then taking out the main cutter bar (1), so that the burr of the orifice of the spatial intersection hole is removed completely.
