Industrial cooling plate welding seam air tightness detection device

Abstract

The invention discloses an industrial cooling plate welding seam air tightness detection device in the technical field of welding seam air tightness detection, and the device comprises a detection table, the upper and lower parts of the detection table are uniformly and symmetrically provided with first moving grooves, the interior of each first moving groove is slidably connected with a first extrusion plate, and the inner side of each first extrusion plate is provided with a first elastic rubber block. A blowing device is installed between the two corresponding first extrusion plates in the first moving groove on the lower portion, second moving grooves are formed in the detection table in a bilateral symmetry mode, second extrusion plates are installed in the second moving grooves, and second elastic rubber blocks are arranged on the inner sides of the second extrusion plates. The device is provided with the first extrusion plates and the second extrusion plates, the first extrusion plates and the second extrusion plates wrap a welding seam around the cooling plate through the first elastic rubber block and the second elastic rubber block, so that when air blowing equipment blows air to carry out leakage detection, the detection result of a corresponding position is not influenced by other leakage positions, and the detection result is relatively accurate.

Description

technical field [0001] The invention relates to the technical field of weld seam air tightness detection, in particular to an industrial cooling plate weld seam air tightness detection device. Background technique [0002] At present, in the industry, due to the complex internal structure of some cooling plates, when it is molded and cast, it needs to be cast in two parts, and finally the two parts are welded into a whole, and a weld will be formed after welding , in order for the cooling plate to be used normally, it is necessary to conduct an air tightness test on the weld seam on the cooling plate after processing. In order to save costs, some manufacturers only arrange one person to carry out the inspection work. Clamping, and this will cause the location of the leak on the cooling plate weld to be tight, resulting in inaccurate test results. To this end, we propose an industrial cold plate weld air tightness testing device. Contents of the invention [0003] The obj...
