APPARATUS AND METHOD FOR INSPECTING REMAINING PRESSURE IN AIR SPRING

摘要

The present invention relates to an apparatus and a method for inspecting remaining pressure in an air spring. The purpose of the present invention is to prevent damage to an air spring or a relevant component due to excessive remaining pressure by forcibly discharging gas inside the air spring to the outside in order to reduce the remaining pressure inside the air spring to below a permissible range, and also is to easily sort out an air spring which has an excessive remaining pressure. The apparatus for inspecting remaining pressure in an air spring comprises: a frame (100); a fixating module (200) which is installed on the frame (100), and fixates an air spring by being combined with the air spring being inspected; a pressurizing member (300) which forcibly discharges gas inside the air spring by pressurizing the air spring fixated by the fixating module (200); a cylinder (400) which is installed on the frame (100), and moves the pressurizing member (300) by being connected with the pressurizing member (300); a load cell (500) which detects loads applied to the air spring by the pressurizing member (300) when pressurizing the air spring by the pressurizing member (300); and a controller (600) which detects the remaining pressure inside the relevant air spring using the load value detected by the load cell (500).
