Welding locating device for heat exchange tube

Abstract

The invention provides a welding locating device for a heat exchange tube and applies to the technical field of heat exchange tubes of radiators. A rotary ejector pin (3) is screwed in a threaded hole in the upper part of a device frame (1) of the welding locating device for the heat exchange tube, and a locating block (2) comprises a locating block body (4), a connecting arm I (5) and a connecting arm II (6); the connecting arm I (5) is movably connected with one side of the lower part of the device frame (1); the connecting arm II (6) is movably connected with the other side of the lower part of the device frame (1), and a locating block limiting groove (7) is formed in the locating block body (4); and a locating step (8) is arranged on the surface of the locating block limiting groove (7), and a frame limiting groove (9) is formed in the lower part of the device frame (1). According to the welding locating device for the heat exchange tube, two heat exchange tubes needing to be welded can be rapidly and accurately assembled, so that a heat exchange gun can be accurately aligned to a weld joint after being arranged on the heat exchange tubes in a sleeving mode; and efficient and high-quality welding is achieved, and the welding efficiency of the heat exchange tubes is improved.

Description

technical field [0001] The invention belongs to the technical field of radiator heat exchange tubes, and more specifically relates to a welding positioning device for heat exchange tubes. Background technique [0002] When the radiator heat exchange tube is welded by an automatic welding machine, when the welding torch clamps the assembled heat exchange tube and prepares to weld the two heat exchange tubes, it is difficult for the tungsten needle of the automatic welding torch to accurately align the weld seam. In the prior art, visual estimation or measurement with a scale is mainly used, and the error is relatively large. Therefore, there are the following problems: <1> The positioning is not accurate enough, the error is large, and the batch production varies greatly; <2> The operation is complicated, and the working hours are delayed for a long time, resulting in low welding efficiency and affecting production; <3> Work experience requirements for worke...
