Embodiment Construction
[0017] figure 1 It is a schematic diagram of the assembly structure of the present invention and the crankshaft. from figure 1 It can be seen that a crankshaft oil hole drilling jig includes a clamp body 15, a clamping mechanism, a connecting rod positioning mechanism, a drilling formwork frame mechanism, and the like. All kinds of crankshafts are clamped and fixed in the fixture according to drilling needs, so as to carry out the operation of drilling crankshaft oil holes. The jigsaw mechanism is generally a main shaft jigsaw mechanism, and it can also be two kinds of spindle jigsaw mechanism and connecting rod jigsaw mechanism. The connecting rod jig frame mechanism can be selectively used as required. In this way, it can not only be used to drill the straight oil hole of the main journal of the crankshaft, but also can drill the straight oil hole of the connecting rod neck according to the needs.
[0018] from figure 1 , figure 2 It can be seen that the clamping mech...
