The automatic tightening device for oil plugs in an engine cylinder block of the present invention has the following beneficial effects: through the two tightening mechanisms on the robot, different oil plug structures on different material distribution components are screwed into different oil holes of the engine cylinder block respectively. The whole process is automated and efficient. Specifically, for example, the first tightening mechanism 666 inserts the first oil plugging structure 777 stored in the first material distribution component into the first oil hole of the engine cylinder 100 located on the transmission mechanism 3, and the second tightening mechanism 667 inserts the second oil plugging structure stored in the second material distribution component into the second oil hole of the engine cylinder 100 located on the transmission mechanism 3.
