Fin modular strength testing device

The utility model discloses a wing modularized strength testing device which comprises a base, a positioning module and a loading module, the positioning module is mounted on the base, and the loading module is mounted on the positioning module; the positioning module is used for clamping a fin, and the loading module is used for loading different positions of the fin. The device is simple in structure and low in cost; moreover, the precise control of the output of the air cylinder is realized by utilizing a secondary pressure regulating gas circuit formed by combining the primary pressure regulating valve and the precise pressure regulating valve, so that the injury of equipment to a human body is avoided. In addition, the air paths of the plurality of air cylinders are connected in parallel and can be independently controlled, and loads of different sizes can be loaded to a plurality of loading points of the tested wing panel at the same time. 本实用新型公开了一种翼片模块化强度测试装置，包括底座、定位模块、加载模块；定位模块安装在底座上，加载模块安装在定位模块上；所述的
