The connecting rod is one of the main transmission parts of the automobile piston engine. Its function is to convert the linear motion of the piston into the rotary motion of the crankshaft , and transmit the gas pressure acting on the piston group to the crankshaft , so the connecting rod moves up and down. In addition, it also swings left and right to do complex plane movements. When the connecting rod is working, it mainly bears the alternating load generated by the gas pressure and the reciprocating inertial force, and requires sufficient fatigue strength and structural rigidity. At the same time, since the connecting rod is both a transmission part and a moving part, it is not possible to increase the bearing capacity by increasing the size of the connecting rod. It is necessary to comprehensively select materials, structural design, part processing, etc. to ensure the quality of the connecting rod, so the processing of the connecting rod Quality is a key point in determining the quality of the engine. Due to its high efficiency, high precision, high degree of automation and low labor intensity, Longmen Machining Center is widely used by domestic and foreign machinery industry. The gantry five-face machining center produced by Zhongjie Machine Tool Co., Ltd. is used for connecting rod processing. Typical equipment.
The connecting rod is mainly composed of a big head, a small head and a shaft. The big head is a split structure, half is the connecting rod cover, and the other half is connected with the shaft body. The connecting rod is bolted, the big hole and the bearing bush are matched with the crankshaft connecting rod journal. The small head hole and the bushing pass the piston pin and The piston is coupled to transmit the gas expansion pressure acting on the piston to the crank, and is driven by the crank to drive the piston to compress the gas in the cylinder.
