[0002] Welding is the process of connecting metal parts using various fusible alloys (solder). The melting point of solder is lower than that of the material being welded, so that the parts will be welded through intermolecular contact on their surface without being melted.

[0003] However, in the prior art, when existing welding machines weld tubular components, most of them are manually loaded with two tubular components onto the welding machine workbench and the ports are butted together before welding. However, since the two tubular components are cylindrical and easy to move relative to each other, it is difficult to manually butt the ports together, and the final butt connection accuracy is also poor, resulting in a low yield rate of the welding machine. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art: since the two tubular components are cylindrical and easy to move relative to each other, it is difficult to manually dock the ports, and the final docking accuracy is also poor, resulting in a low yield rate of the welding machine.

[0006] As a preferred embodiment, electric telescopic rods are fixedly connected to both sides of the welding machine body, and one end of the electric telescopic rod is fixedly connected to the mounting plate.

[0007] As a preferred embodiment, the first motor is wrapped with a protective cover, the rotating shaft is connected through the protective cover, and one end of the protective cover is fixedly connected to the slider.

[0008] As a preferred embodiment, a pressing arc plate is embedded in the inner surface of the feeding sleeve, and one end of the pressing arc plate is rotatably connected to a No. 1 screw rod, which is threadedly connected to the feeding sleeve.

[0009] As a preferred implementation, a rubber pressing layer is fixedly connected to one side surface of the pressing arc plate.

[0010] Compared with the prior art, the advantages and positive effects of the utility model are:

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: a feeding mechanism of a welding machine, including a welding machine body 1, mounting plates 3 are arranged on both sides of the welding machine body 1, and sliders 4 are slidably connected to the mounting plates 3, the sliders 4 are slidably connected to the welding machine body 1, a No. 1 motor 5 is fixedly connected to the slider 4, a rotating shaft 7 is fixedly connected to the output end of the No. 1 motor 5, and a connecting ring 8 is fixedly connected to one end of the rotating shaft 7. With the help of the No. 1 motor 5, the rotating shaft 7 and the connecting ring 8, it is convenient to control the feeding sleeve 9 to carry the tubular component for rotational movement, so that the tubular component is changed from vertical to horizontal. The feeding sleeve 9 is rotatably connected to the connecting ring 8. The feeding sleeve 9 is vertically arranged at the beginning, so that its opening faces upward, which is convenient for the staff to aim at the opening when inserting the tubular component, so that the tubular component can be quickly inserted into the feeding sleeve 9, and during welding When the machine body 1 is not in use, the vertical feeding sleeve 9 can also reduce the overall space occupied by the device. One end of the slider 4 is snap-connected with an insert block 12, and one side of the insert block 12 is fixedly connected with a sliding block 13, and the sliding block 13 is slidably connected to the welding machine body 1, and a No. 2 screw rod 14 is rotatably connected in the slide groove of the welding machine body 1, and a built-in groove is provided on one side of the slide groove of the welding machine body 1, and a No. 2 motor 15 is provided in the built-in groove, one end of the No. 2 screw rod 14 is fixedly connected to the output end of the No. 2 motor 15 and is threadedly connected to the sliding block 13. The No. 2 screw rod 14 is rotated by the No. 2 motor 15 to drive the sliding block 13 to move, and then the insert block 12 pulls the slider 4 to move, so that the feeding sleeve 9 carries the tubular component to move, so that the tubular component is fed to the workbench of the welding machine body 1, and the two tubular components are relatively stably and accurately docked.

[0021] Example 2

[0022] like Figure 1-4As shown, electric telescopic rods 2 are fixedly connected to both sides of the welding machine body 1, and one end of the electric telescopic rods 2 is fixedly connected to the mounting plate 3. By contracting the electric telescopic rods 2, the mounting plate 3 is lowered, and then the feeding sleeve 9 is lowered as a whole. By lowering the height of the opening of the feeding sleeve 9, the tubular component does not need to be lifted too high before being installed into the feeding sleeve 9, so that the tubular component can be more easily installed in the feeding sleeve 9. A protective cover 6 is wrapped around the No. 1 motor 5, and the rotating shaft 7 is connected with the protective cover 6 through, and one end of the protective cover 6 is fixedly connected to the slider 4. The protective cover 6 plays a protective role for the No. 1 motor 5 to prevent the sparks generated by the welding machine body 1 during welding from directly contacting the No. 1 motor 5 The contact causes damage to the No. 1 motor 5. A pressing arc plate 10 is embedded in the inner surface of the feeding sleeve 9, and one end of the pressing arc plate 10 is rotatably connected to a No. 1 screw rod 11. The No. 1 screw rod 11 is threadedly connected to the feeding sleeve 9. When the diameter of the tubular component is smaller than the diameter of the feeding sleeve 9, the pressing arc plate 10 is pushed forward by rotating the No. 1 screw rod 11 to squeeze and fix the tubular component, thereby improving the adaptability of the feeding sleeve 9 to the installation of tubular components of different diameters. A rubber pressing layer is fixedly connected to the surface of one side of the pressing arc plate 10. With the help of the rubber pressing layer, the friction of the pressing surface of the pressing arc plate 10 is increased, thereby improving the stability of the extrusion and fixation of the tubular component.

[0023] Working principle:

[0024] like Figure 1-4 As shown, when the utility model is in use, the user first loads the tubular component into the feeding sleeve 9. If the diameter of the tubular component is smaller than the feeding sleeve 9, the No. 1 screw rod 11 is rotated to allow the pressing arc plate 10 to push forward to squeeze and fix the tubular component, and then the electric telescopic rod 2 is extended to drive the mounting plate 3 to move upward so that the mounting plate 3 is finally flush with the workbench of the welding machine body 1. Then, the No. 1 motor 5 in the protective cover 6 is started to drive the rotating shaft 7 and the connecting ring 8 to rotate ninety degrees, so that the feeding sleeve 9 and the tubular component are turned from vertical to horizontal, and then the No. 2 motor 15 is turned on. The No. 2 motor 15 drives the No. 2 screw rod 14 to rotate and then drives the movement of the sliding block 13 and the plug block 12. The plug block 12 pulls the slider 4 to move, thereby driving the feeding sleeve 9 to carry the tubular component to move, so that the tubular component is fed to the workbench of the welding machine body 1, and the two tubular components are relatively stably and accurately docked, and then the welding machine body 1 is controlled to start welding the docking of the tubular components.
