Multi-shaft drilling head machine tool for side surface thread bottom hole machining of crank case

The utility model discloses a multi-shaft drilling head machine tool for side surface thread bottom hole machining of a crank case. The multi-shaft drilling head machine tool comprises a work-piece installation table and a multi-shaft drilling machine head. The crank case is fixed to the work-piece installation table, and bottom hole drilling is carried out on the side surface thread of the crank case through the multi-shaft drilling machine head. The multi-shaft drilling head machine tool is a production machine tool good in effect, effectively overcomes the shortcomings that the location degree of side surface thread drilling of a gear case is difficult to guarantee, the machining efficiency is low and the labor intensity is high during existing production, improves and stabilizes the accuracy of the location degree of drilling, and reduces the number of times of drilling. Meanwhile, the multi-shaft drilling head machine tool is beneficial for replacing manual operation through a numerical control mode, imp
