Spring support hanger assembly methods commonly used are the following

1) complete exchange method. In a similar part, the optional assembly part is not repaired and meets the specified assembly requirements. This assembly method is called the complete exchange method. The advantage of the full exchange method is that the assembly operation is simple and the production efficiency is high. The utility model is suitable for the low number of components, the low precision requirement or the mass production.

2) select assembly method. The whole set of spring supports and hangers shall properly enlarge the manufacturing tolerances of the parts to the extent of economic feasibility, and then select the suitable parts for assembly to ensure the specified assembly crown. The parts are divided into several groups according to tolerances, and then assembled in groups to meet the specified requirements. The advantage of choosing assembly method is to reduce the processing cost, and the matching precision of parts is high after grouping selection. It is often used in mass production with high assembly accuracy and less number of components.

3) repair method. An assembly method that repairs the required amount of repair on a specified part to achieve assembly accuracy. The advantages of the repair method are that it can reduce the manufacturing accuracy requirements of parts, and is suitable for single and small batch production as well as occasions requiring high assembly accuracy.

4) allocation method: the assembly method for adjusting the position or size of a part in order to achieve assembly accuracy, such as changing gaskets, gaskets, sleeves, etc., to control the size of the adjusting parts. The advantage of blending method is that parts can be machined according to economic tolerance precision. It is suitable for all kinds of assembly occasions except for precision fittings that must be selected by grouping.
