The methods to ensure assembly accuracy can be summarized into four categories: exchange assembly method, selective assembly method, repair assembly method and adjustment assembly method.
Interchangeable assembly method refers to the assembly method that can still meet the specified assembly accuracy requirements after parts are exchanged in the assembly process.
Selective assembly method is an assembly method that enlarges the manufacturing tolerance of each part in the matching pair to economic accuracy, and then selects appropriate parts for assembly to ensure the assembly accuracy requirements.
Repair and assembly method refers to the assembly method that all relevant mold parts are processed and manufactured according to economic accuracy. During assembly, the reserved repair quantity of specified parts is repaired according to needs to ensure the assembly accuracy.
Adjustment assembly method refers to the method that all relevant die parts are processed and manufactured according to economic accuracy, and the relative position of adjustable parts in the die is changed or appropriate adjusting parts are selected to achieve assembly accuracy during assembly.
