Tooling enabling located block to be arranged on heat exchange tube

The invention discloses a tooling enabling a located block to be arranged on a heat exchange tube conveniently, wherein an installation size of the located block is accurate. The tooling enabling the located block to be arranged on the heat exchange tube comprises a rack. The rack is provided with a pair of supports, and the two supports are connected through three fixing rods which are arranged in a triangle shape. A plurality of supporting rings are arranged between the three supporting rods, and the supporting rings are respectively provided with a tight compressing device which enables a fixing block to be tightly compressed on the heat exchange tube. The located block to be arranged on heat exchange tube has the advantages that the heat exchange tube is arranged in the supporting tings, the fixing block is arranged on the heat exchange tube, the tight compressing device enables the blocking block to be tightly pressed on the heat exchange tube, welding of the fixing block is achieved, and the above-mentioned operating process is convenient, fast and easy.
