Problems solved by technology

[0004] In order to ensure the performance of the refrigerator, the coaxiality between the base body of the gas distribution piston and the piston rod is very high, which not only requires a particularly high machining accuracy of the parts, but also cannot be achieved through ordinary assembly methods according to the structure of the base body of the gas distribution piston and the piston rod. Axial accuracy requirements require design and installation tooling guarantee

Abstract

The invention discloses a self-centering coaxial assembling device for a gas distribution piston of a Stirling refrigerator, comprising: an installation base, wherein the installation base is provided with a first base hole and a second base hole arranged opposite and coaxial; The gas distribution piston base coaxial mechanism is self-centering and coaxial with the gas distribution piston base; and the piston rod coaxial mechanism is used for the piston rod self-centering and coaxial; the gas distribution piston base coaxial mechanism is installed in the first base hole and A radial pressure is applied to the base body of the gas distribution piston to realize self-centering and coaxiality of the base body of the gas distribution piston; The invention ensures good coaxiality between the base body of the gas distribution piston and the piston rod, and eliminates the problem of poor precision caused by the machining accuracy and the installation process, thereby ensuring the smoothness and fluency of the reciprocating motion of the gas distribution piston. At the same time, the sealing efficiency and refrigeration efficiency of the Stirling refrigerator are guaranteed.

Description

technical field [0001] The invention relates to the technical field of Stirling refrigerator assembly, in particular to a self-centering coaxial assembly device for a gas distribution piston of a Stirling refrigerator. Background technique [0002] The free-piston Stirling refrigerator is a gas mechanical refrigerator that uses the alternating reciprocating motion of the power piston part and the gas distribution piston part to realize the periodic expansion and compression of the gas in the cylinder to obtain the cooling capacity. Free-piston Stirling refrigerator adopts advanced technologies such as linear motor drive, leaf spring support, gap seal, pure pneumatic expander, etc. It has the advantages of high reliability, low vibration, long life, and maintenance-free. In the field of ultra-low temperature refrigeration, it is relatively Compared with traditional refrigeration equipment, Stirling refrigerator has more advantages. [0003] Free piston Stirling refrigerator ...
