Square inclined block drill
The transformer core assembly is fastened by four channel steels and a pull screw. The concave surface of the channel is a bevel. When assembling, the slanting pad must be used to flatten and tighten the pull screw and the foot screw. When machining the inclined block, the quality of the drilled hole on the inclined surface is not guaranteed, and the clamping is also difficult. For this I designed a drill (as shown). The car has a drill sleeve 1 with a hole diameter of φ11_0~(+0.1)mm. The car mold base 3 cooperates with the drill sleeve 1 and is milled on the drill base 3
