DETAILED DESCRIPTION

[0020] The technical solution of the present utility model will be further described below with reference to the accompanying drawings.

[0021] See attached Figures 1 to 5 The tube-to-sheet welding machine shown in the figure comprises a positioning portion 100 and a rotating portion 200, wherein the positioning portion 100 comprises a core shaft 101 concentric with the welding hole and a positioning block 102 connected to the core shaft 101, the rotating portion 200 comprises a rotating assembly 210 rotating around the core shaft 101 and a welding assembly 220 arranged on the rotating assembly 210, the end of the core shaft 101 is connected to the positioning block 102, and the tail is connected to the rotating assembly 210, and the welding gun head 221 in the welding assembly 220 faces the welding hole.

[0022] In this embodiment, the positioning block 102 and the core shaft 101 are respectively located on both sides of the plate 300 where the welding hole is located. The end of the core shaft 101 is connected to the positioning block 102. The positioning block 102 is provided with a screw 103 that can pass through the welding hole at one end facing the welding hole. The screw 103 is threadedly connected to the core shaft 101 at the other end of the welding hole.

[0023] At the same time, the end face of the positioning block 102 facing the welding hole is concentric with the welding hole and has an inner diameter larger than the inner diameter of the welding hole. After the positioning block 102 is connected to the core shaft 101, since the inner diameter of the end face of the positioning block 102 facing the welding hole is larger than the inner diameter of the welding hole, the positioning block 102 is positioned on the left side of the welding hole and the core shaft 101 is positioned on the right side of the welding hole, completing the concentric operation of the positioning part 100 and the welding hole.

[0024] In this embodiment, the rotating assembly 210 includes a core shaft support sleeve 211, a support sleeve end cover 212, a welding part substrate 213, an arc length adjustment mounting bracket 214 and a welding gun mounting plate 215. The tail of the core shaft 101 extends into the support sleeve end cover 212 and is rotatably connected to the support sleeve end cover 212. The tail of the support sleeve end cover 212 is connected to the core shaft support sleeve 211, and the tail of the core shaft support sleeve 211 is connected to the welding part substrate 213. An arc length adjustment mounting bracket 214 is provided on the end surface of the welding part substrate 213 facing the welding hole position. A welding gun mounting plate 215 is slidably connected to the arc length adjustment mounting bracket 214, and a welding assembly 220 is installed on the side of the welding gun mounting plate 215 facing the welding hole position.

[0025] At the same time, a slide groove 216 is provided on the arc length adjustment mounting bracket 214 along the horizontal direction, and a slider 217 is slidingly provided in the slide groove 216. After the welding gun mounting plate 215 is fixedly connected to the slider 217, it moves in the slide groove 216 following the slider 217. This arrangement ensures that after the positioning part 100 is concentric with the welding hole, the rotating assembly 210 set on the core shaft 101 rotates around the core shaft 101, and the circumference formed by the rotation is also concentric with the welding hole, that is, it ensures that the welding arc of the welding assembly 220 installed on the rotating assembly 210 is concentric with the welding hole. The arrangement of the slide groove 216 and the slider 217 can extend the welding assembly 220 installed on the welding gun mounting plate 215 into the vicinity of the welding hole along the space between the pipe fittings.

[0026] In this embodiment, a positioning sleeve 218 is rotatably connected to the core shaft 101, and a connecting plate 219 is provided on the positioning sleeve 218. One end of the connecting plate 219 is fixedly connected to the positioning sleeve 218, and the other end is fixedly connected to the welding gun mounting plate 215 by bolts after the relative position of the welding gun mounting plate 215 and the arc length adjustment mounting bracket 214 is adjusted. After the welding assembly 220 follows the welding gun mounting plate 215 and extends into the vicinity of the welding hole, the welding gun mounting plate 215 and the connecting plate 219 are fixedly connected by bolts, thereby completing the limitation of the axial position of the welding assembly 220 in the pipe fitting to prevent sliding during the welding process.

[0027] In this embodiment, the welding assembly 220 includes a welding gun seat 222 and a welding gun head 221. The welding gun seat 222 is fixedly mounted on the end of the welding gun mounting plate 215 facing the welding hole. The welding gun head 221 is arranged on the welding gun seat 222 and is rotatably connected to the welding gun seat 222. The welding gun head 221 is rotatably connected to the welding gun seat 222, which facilitates fine-tuning of the final welding point and further improves the accuracy of the welding point.
