The disadvantage of this type is that the number of hydraulic presses (or servo cylinders) is large, the equipment cost is greatly increased, and the press spacing arrangement is not reduced for small cylinders; 2. the engine has 5 main bearing caps, and is connected with 5 pressure heads (the pressure heads are provided with clamping jaws for clamping the main bearing caps) by adopting 1 hydraulic press (or a servo electric cylinder) and then are pressed together. The disadvantage of this type is that the engine with larger press-fitting force cannot be assembled, and the independent pressure adjustment of each main bearing cap cannot be realized and the press-fitting of each main bearing cap cannot be guaranteed in place; 3. the engine has 5 main bearing caps, and two pressure heads (the pressure heads are provided with clamping jaws for clamping the main bearing caps) are singly connected by adopting 2 hydraulic presses (or servo electric cylinders), and then the main bearing caps are subjected to press fitting at 5 positions through displacement. The structure considers the characteristics of optimal cost and stable workpiece press-fitting of the two pressure heads simultaneously.
