Device for detecting air impermeability of component and detecting method thereof

Abstract

The invention discloses a part air tightness detection device and a detection method thereof, which sequentially comprise from bottom to top: a base plate, a support rod, an upper connecting plate, a hydraulic action rod, and a tooling mechanism; wherein, the two sides of the base plate are arranged symmetrically There is a threaded hole for installing the support rod; a through hole is processed at the center of the bottom plate; the tooling mechanism includes: a mounting slot for detecting the outer contour of the workpiece, a tooling platform, and an overvoltage protection mechanism; the center position of the tooling platform is An air inlet installation hole is provided; the upper end surface of the tooling platform is provided with a detection workpiece outer contour installation card slot installation position; the detection workpiece outer contour installation card slot passes through the detection workpiece set on the upper end surface of the tooling platform The outer contour installation card slot installation position is fixedly installed on the upper end surface of the tooling platform; the overpressure protection mechanism includes: a hydraulic rod, and a pressure regulating valve; the pressure regulating valve is used to control the bearing pressure of the hydraulic rod .

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a component air tightness detection device and a detection method thereof. Background technique [0002] ​The air tightness test of parts is often encountered in industrial production. At present, the air tightness test of parts is mostly manual visual inspection method, that is, put the part into the liquid to inflate, and then observe whether the outer surface of the part is There are air bubbles leaking; in addition, there are some special mechanical testing equipment, but they are not perfect and mature. The main aspects are that the testing results are not accurate enough, the installation sealing is not enough, and the parts installation protection is not enough, which leads to inaccurate measurement results. Accurate, and the workpiece is damaged during the measurement process. In view of the above problems, the applicant has developed a part air tightness detection de...
