Assembly tooling and assembly method of timing chain system of engine

Abstract

The invention provides an assembly tooling and an assembly method of a timing chain system of an engine, thereby improving the assembly efficiency and the quality and facilitating the inventory management of parts. The shape of the assembly tooling tallies with the shape of the well assembled timing chain system, the tooling is provided with position-limiting concave parts by corresponding all parts of the timing chain system, the tooling is provided with through holes with the hole diameter which is larger than the diameter of mounting bolts in the positions which correspond to mounting holes of all the parts, and the tooling is provided with the through holes with the hole diameter which is slightly larger than shaft holes of a chain wheel in the positions which correspond to all the shaft holes of the chain wheel. A subassembly is formed by using a special tooling to fix all the parts of the timing chain system according to the assembly positions of the whole machine, thereby facilitating the management of the parts; when the assembly is carried out on a production line, all the parts of the timing system can be aligned and assembled in place once by only aligning the relative positions of the tooling and the engine, thereby greatly reducing the labor quantity and the labor intensity of workers, and improving the assembly efficiency and the assembly quality.

Description

technical field [0001] The invention belongs to the technical field of engine manufacturing, and in particular relates to an assembly tool and method for an engine timing chain system. Background technique [0002] At present, on the assembly lines of various engine manufacturers, the assembly process of the timing chain system is to assemble individual components to the engine one by one. The assembly of such a timing chain system requires several stations to complete, and the labor consumption is relatively large. Large, slow production tempo, difficult to guarantee assembly quality, and not conducive to the inventory and management of parts, it is easy to cause a shortage of certain parts, affecting production and inventory preparation. Contents of the invention [0003] The purpose of the present invention is to propose an assembly tool and assembly method for an engine timing chain system, so as to improve assembly efficiency and quality, and facilitate inventory mana...
