Air tightness detection device

Abstract

The present invention discloses an air tightness detection device. The device employs a cylinder as a driving part to cooperate with an air tightness joint to replace manual work to perform sealing of a cylinder to be detected so as to reduce the worker fatigue work and improve the detection efficiency. The device concretely comprises: a rack, an air tightness structure installed on the rack, an air passage unit and a pressure detection unit. The air tightness structure comprises a cylinder and an air tightness joint installed at the end portion of a cylinder piston rod, when the cylinder is operated, the motion of the piston rod is employed to perform sealing butt joint of the air tightness joint and the air inlet hole of a device to be detected; the air passage unit supply air source for the motion of the cylinder, and air is filled to the device to be detected through the air tightness joint after the air inlet hole of the device to be detected is in sealing butt joint with the air tightness joint; and the pressure detection unit performs pressure detection of the device to be detected filled with air to determine the air tightness of the device to be detected.

Description

technical field [0001] The invention relates to a detection device, in particular to an air tightness detection device. Background technique [0002] At present, when testing the airtightness of a certain type of cylinder, a manual detection platform is often used. During the detection, the packaging cylinder needs to be placed flat on the work table, and the sealing joint is installed manually; the assembly is difficult and the sealing performance is poor during installation, resulting in The detection efficiency is low, and the air supply hose is easily damaged after repeated stretching, and the airtight test needs to be repeated many times to be successful. As a result, the airtight test process takes a long time and has high labor costs, which has become the bottleneck process of the assembly line. In order to save costs and improve production efficiency, it is necessary to design an easy-to-operate automatic airtight test device. Contents of the invention [0003] I...
