The connecting rod group bears the action force of gas transmitted by the piston pin and the action of swinging of the connecting rod group and reciprocating inertia force of the piston group, and the magnitude and the direction of the forces are periodically changed. The connecting rod is subjected to alternating loads such as compression, tension and the like. The connecting rod must have sufficient fatigue strength and structural rigidity. The fatigue strength is insufficient, so that the connecting rod body or the connecting rod bolt is often broken, and further, a major accident of complete machine damage is generated. If the rigidity is insufficient, the bending deformation of the rod body and the out-of-round deformation of the big end of the connecting rod are caused, so that the eccentric wear of the piston, the cylinder, the bearing, the crank pin and the like is caused.
The industries such as ships, internal combustion engines, engineering machinery and the like are not separated from the connecting rod parts. Because the connecting rod is subjected to large force during movement, high-strength materials such as alloy steel or spheroidal graphite cast iron are usually selected. The machining of the connecting rod is like adopting twist drill machining, and the machining cost is high, the machining efficiency is low and the drilling skewness is poor. The deep hole drilling can achieve satisfactory machining quality and extremely high machining efficiency. Therefore, the special deep hole drilling machine tool is used for machining the connecting rod oil hole reliably, efficiently and stably, and in actual machining, the connecting rod oil hole is divided into a straight oil hole and an inclined oil hole, and a special tool is used for clamping in order to improve efficiency and ensure the precision of machining the hole and the position of an inlet and an outlet. A special bevel guide sleeve is arranged at the inlet to ensure the balance state when the primary turning tool is contacted with the ring surface of the connecting rod, and the cutting is performed with small feeding until the guide part of the whole tool is cut into the material.
At present, most of the punching of the connecting rod oil hole is still remained in the manual hand-held drill bit for punching, so that manual operation is needed, the punching efficiency is low, the working efficiency is influenced, the punching speed of the connecting rod oil hole is not in line with the requirement, and a machine is needed to solve the problem.
