The connecting rod is one of the main transmission components of Bare Engine. Its function is to transmit the force borne by the piston to the crankshaft and convert the reciprocating motion of the piston into the rotational motion of the crankshaft.

It is mainly composed of a small head, a rod body and a large head. The large head is a separate structure, and the connecting rod body and the connecting rod cover are bolted and assembled with the crankshaft.

The structure of the connecting rod directly affects the reliability and economy of the machining process. Bare Engine are mass-produced, so they have high rationality in the structural process.

The starting point for formulating the process route should be to reasonably guarantee the geometry, dimensional accuracy and position accuracy of the parts.

Since the processing of MG Roewe Maxus Engine is mass-produced, advanced processes and high-productivity special machine tools should be widely used.

To achieve automation of machining, assembly of connecting rod caps and connecting rod bodies, weighing, inspection, cleaning and packaging. In addition, economic effects should also be considered to reduce production costs.
