Abstract

The invention discloses manufacture of an automobile part connection rod. The automobile part connection rod comprises a small head hole, a crankshaft connection rod shaft, an air cylinder combustion chamber, a piston and a big head hole, wherein a small head is connected with the piston through a piston pin, the big head hole is connected with the crankshaft connection rod shaft, the air cylinder combustion chamber is connected with the top face of the piston, and the piston is connected with the crankshaft connection rod shaft. The manufacture operation is simple, the flexibility of the connection rod can be increased, and the using time can be saved.

Description

technical field [0001] The invention relates to the manufacture of auto parts, in particular to the manufacture of connecting rods of auto parts, and belongs to the field of auto parts manufacturing. Background technique [0002] As the foundation of the automobile industry, auto parts are a necessary factor to support the sustainable and healthy development of the automobile industry. In particular, the current independent development and innovation in the automobile industry is vigorously and vigorously carried out, and it needs a strong parts system to support. The independent brand and technological innovation of the whole vehicle need parts as the foundation, and the independent innovation of parts has great impact on the whole car industry. They are mutually influencing and interacting. Without independent brands of complete vehicles, it is difficult to develop the R&D and innovation capabilities of a strong parts system. Without the support of a strong parts system, i...
