The vertical plate 2 and slanted support plate 3 are vertically mounted on the mounting base plate 1. The slanted bottom plate 4 is positioned on the top surface of the vertical plate 2 and slanted support plate 3, maintaining a predetermined angle with the mounting base plate 1. This angle is the same as the angle between the gear's slanted oil hole and its end face. A toothed positioning block 6 is provided on the slanted bottom plate 4, with a toothed positioning surface that meshes with the gear. When clamping the gear, one end face of the gear is pressed against the slanted bottom plate 4, meshing with the toothed positioning surface. A V-block 7 is slidably mounted on the slanted bottom plate 4 on the opposite side of the toothed positioning block 6. A driving device for driving the V-block 7 is provided on the vertical plate 2. The V-block 7 presses against the other end of the gear, causing the gear to press against the toothed positioning block 6. A drill jig 5 is provided on the inclined base plate 4. A drill sleeve 9 with its axis perpendicular to the mounting base plate 1 is provided on the drill jig 5. An inclined oil hole can be precisely drilled on the gear by passing the drill bit through the drill sleeve 9.
