The interference fit assembly method in instrument manufacturing and its role in improving instrument stability

Introduction

The instrument manufacturing industry is the cornerstone of scientific and technological development, and the accuracy and stability of instruments and equipment are directly related to the success or failure of scientific research and production activities. In the process of instrument manufacturing, interference fit assembly technology is widely used, which effectively improves the accuracy and stability of instruments and equipment through reasonable design and precise manufacturing. This article will deeply explore the interference fit assembly method and its application in improving the stability of instruments.

Two, Overview of interference fit assembly method

Interference fit assembly refers to the assembly of holes and shafts with interference fit, ensuring that a certain amount of interference fit is generated between the hole and shaft during the assembly process to achieve a tight connection between them. The interference fit assembly usually includes the assembly process, assembly accuracy, and assembly method of interference fit assembly, and its assembly accuracy directly affects the accuracy and stability of the instruments and equipment.

Interference fit assembly process

　　The interference fit assembly process mainly includes three stages: preparation before assembly, assembly process, and inspection andadjustment after assembly. The preparation before assembly includes precise measurement of the hole and shaft to determine their size tolerance; the assembly process mainly includes assembly, adjustment of interference fit, and inspection and adjustment after assembly; the inspection and adjustment after assembly is mainly through measuring the accuracy of the instrument and equipment to ensure that it meets the design requirements.

Interference fit assembly accuracy

　　The interference fit assembly accuracy refers to the size of the interference fit between the hole and shaft after assembly. The accuracy of interference fit assembly directly affects the accuracy and stability of the assembled instruments and equipment. The accuracy of interference fit assembly mainly depends on the manufacturing accuracy of the hole and shaft, the operation accuracy during the assembly process, and the inspection and adjustment after assembly.

Interference fit assembly method

The interference fit assembly method mainly includes cold assembly, hot assembly, and pressure fitting methods. Cold assembly refers to assembling the hole and shaft at room temperature, and then adjusting the interference fit to achieve assembly accuracy; hot assembly refers to assembling the hole and shaft at high temperature, and then adjusting the interference fit to achieve assembly accuracy; pressure fitting refers to assembling the hole and shaft together by applying pressure, and then adjusting the interference fit to achieve assembly accuracy.
