A high-efficiency airtight detection device

Abstract

The application relates to the technical field of intelligent manufacturing, in particular to an efficient air-tightness detection device, which comprises a rack, a bottom plate arranged in the rack, a sealing cover arranged on the bottom plate, a pressing device arranged on the upper side of the sealing cover and connected with the rack, a workpiece positioning seat arranged on the bottom plate in the sealing cover, an air-tightness detection pipe connected with an air-tightness detector, a gas suction pipe connected with an external gas suction equipment, a sealing flange arranged on the bottom plate, a sealing concave edge arranged on the bottom surface of the sealing cover and matched with the sealing flange, a first sealing element arranged between the contact surface of the sealing flange and the sealing concave edge, a plurality of lower avoiding grooves arranged on the sealing flange, upper avoiding grooves arranged on the sealing concave edge and matched with the lower avoiding grooves, and a sealing joint arranged outside the sealing cover opposite to the lower avoiding grooves, and the sealing joint is connected with a pushing cylinder on one side. The sealing cover and the sealing flange of the bottom plate form a detection space which is more matched with the workpiece, the vacuumization is faster, the side leakage sensitivity is higher, and the detection efficiency is higher.
