A drive shaft hole 104 for the drive shaft inside the divider box body 1 to pass through is provided on the right side of the positioning reference surface 101;

[0021] The drilling tooling body 2 includes an L-shaped positioning plate 201. The L-shaped positioning plate 201 is rough and finish ground using a grinding machine to ensure flatness and perpendicularity. A positioning hole 202 is provided on the front side of the L-shaped positioning plate 201. A positioning boss ring 205 aligned and communicated with the positioning hole 202 is fixedly connected to the front inner wall of the L-shaped positioning plate 201. The positioning boss ring 205 is movably sleeved in the front positioning reference hole 103. The positioning boss ring 205 and the positioning reference hole 103 cooperate to position the position of the L-shaped positioning plate 201. The outer shape of the positioning boss ring 205 is rough and finish milled using a machining center to ensure the surface roughness of the mating surface between the positioning boss ring 205 and the L-shaped positioning plate 201, and at the same time ensure the perpendicularity between the L-shaped positioning plate 201 and the positioning boss ring 205 after assembly;

[0022] The front inner wall and the right inner wall of the L-shaped positioning plate 201 are in movable contact with the front side and the positioning reference surface 101 of the divider box body 1. Two bolt grooves 102 are provided at the bottom right of the positioning reference surface 101. Two bolt holes 204 are provided on the right side of the L-shaped positioning plate 201. The bottom bolt hole 204 is aligned and communicated with the front bolt groove 102. A T-shaped fixing bolt is threadedly sleeved in the bolt hole 204 and the corresponding bolt groove 102.
