Description

Technical Field

[0001] The utility model relates to the technical field of copper tube and fin hot-melt welding, in particular to a fixing device used for copper tube and fin hot-melt welding. Background Art

[0002] As a common radiator, finned copper tubes are added with fins at the outer end of the copper tube to increase the heat dissipation effect. According to production needs, it is necessary to produce a finned copper tube. Figure 1 and attached Figure 2 A finned copper tube is shown, wherein the copper tube is a long square tube, and two long fins are respectively arranged at the upper and lower ends of the tube, the fins have the same width and length as the copper tube, and the copper tube and the upper and lower long fins are welded into shape;

[0003] During the welding process of the finned copper tube, the copper tube needs to be welded to two sets of fins. Usually, the two are manually welded by electric welding. Since the copper tube and the fin have a certain width, the staff cannot weld the inner wall when welding them, which makes it impossible to fully weld the copper tube and the fin, and the quality of the finned copper tube after welding is affected. Then, the copper tube and the fin are hot-melt welded. When hot-melt welding is performed on the copper tube and the fin, the copper tube and the fin need to be fixed. When hot-melt welding is performed on the copper tube and the fin, a fixing device is required to fix the copper tube and the fin for hot-melt welding. However, common fixing devices often do not position the copper tube and the fin, which causes the copper tube and the fin to be misaligned, thereby affecting the processing quality.

The device can effectively limit the copper tube and the fin, and before limiting, the positioning mechanism is used to better align the copper tube and the fin, and the mounting block 2 is detachably connected to the workbench 1, so that when facing copper tubes and fins of different lengths, the mounting block 2 can be removed and replaced with mounting blocks 2 of different models to improve the scope of use of the device.

[0029] In an optional embodiment, the insulating positioning mechanism includes a first limit plate 4 and a second limit plate 5, the first limit plate 4 is located in the mounting groove and connected thereto, the upper end of the first limit plate 4 is provided with a first notch along its length direction, the bottom wall of the first notch is provided with a first epoxy plate 7, the second limit plate 5 is slidably set on the first epoxy plate 7, and the mounting block 2 is provided with a driving component for driving the second limit plate 5 to approach or move away from the first notch side wall, and the second limit plate 5 is driven by the driving component to approach the first notch side wall, so that when the second limit plate 5 approaches the first notch side wall, it cooperates with the first notch side wall to position the copper tube and the fin.

[0030] In an optional embodiment, the driving assembly includes a transmission rod 8 and a first limiting plate 9. A first through hole is provided on the side wall of the mounting groove near the second limiting plate 5. The transmission rod 8 is slidably arranged in the first through hole, one end of which is connected to the second limiting plate 5, and the other end of which is provided with a first limiting plate 9. A first spring 10 is provided between the first limiting plate 9 and the mounting block 2. The mounting block 2 is provided with a limiting unit for limiting the transmission rod 8. When the second limiting plate 5 cooperates with the first notch side wall to limit the copper tube and the fin, the transmission rod 8 is limited by the limiting unit, and the first spring 10 is in a compressed state at this time. Therefore, when the limiting unit on the transmission rod 8 is cancelled, the first spring 10 is extended, thereby driving the first limiting plate 9 to move in the opposite direction, thereby driving the transmission rod 8 and the second limiting plate 5 connected thereto to move in the opposite direction, thereby canceling the positioning of the copper tube and the fin.

[0031] In an optional embodiment, the limiting unit includes a fixed block 11 and a limiting rod 12, the fixed block 11 is connected to the mounting block 2, the fixed block 11 is provided with a second through hole, the limiting rod 12 is slidably arranged in the second through hole, the limiting rod 12 is provided with a limiting head 13 at one end facing the transmission rod 8, the limiting head 13 abuts against the transmission rod 8, the other end of the limiting rod 12 is provided with a second limiting plate 14, the second limiting plate 14 and the fixed block 11 are directly provided with a second spring 15, the transmission rod 8 is provided with a limiting groove for the limiting head 13 to extend into, when the transmission rod 8 needs to be limited, the second limiting plate 5 is driven to move by moving the transmission rod 8, and when the second limiting plate 5 moves to position and limit the copper tube and the fin, the first spring 10 is in a compressed state, and the limiting head 13 is in a position The transmission rod 8 can be limited in the limit groove. When it is necessary to cancel the limit of the transmission rod 8, the second limit plate 14 is moved. The second limit plate 14 moves to drive the limit rod 12 to move, thereby driving the limit head 13 to move out of the limit groove, and the second spring 15 is compressed. After the limit head 13 moves out of the limit groove, the transmission rod 8 moves in the opposite direction under the action of the first spring 10 to cancel the limit on the copper tube and the fin. At this time, the limit head 13 abuts against the outer peripheral surface of the transmission rod 8 under the elastic force of the second spring 15. When it is necessary to limit the moved transmission rod 8 again, the transmission rod 8 is moved. When the transmission rod 8 moves, the first spring 10 is compressed, and the limit head 13 slides on the outer peripheral surface of the transmission rod 8. Therefore, when the limit head 13 is driven to move to the limit groove, the limit head 13 enters the limit groove under the elastic force of the second spring 15 to limit the transmission rod 8 again.
