Description

Technical Field

[0001] The utility model relates to an automatic argon arc welding machine. Background Art

[0002] TIG welding is a common metal welding method that uses argon gas to form a protective layer during the welding process to prevent oxidation and contamination, thereby obtaining high-quality welds. TIG welding is mainly suitable for welding high-melting-point and easily oxidized metals such as stainless steel, aluminum, and magnesium.

[0003] The working principle of argon arc welding is: during the welding process, argon gas is sprayed into the welding area through the nozzle to form a thick and dense protective layer to isolate the air. At the same time, an arc is ignited between the electrode (tungsten electrode or welding wire) and the workpiece, and the arc heat is used to heat the welded metal and the filler wire to melt, connecting the workpieces together to obtain a strong welded joint.

[0004] The existing argon arc welding process generally proceeds along the direction of the weld to weld two workpieces together. However, when welding arc or circular welds, the existing argon arc welding requires the operator to have a high level of operation to achieve a better welding effect. The labor cost is high and it is easy to cause welding deviations. Utility Model Content

[0019] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "page", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0020] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0021] In the description of the present utility model, "multiple" means two or more than two, unless otherwise clearly specified and specifically defined. In the present utility model, unless otherwise clearly specified and defined, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal connection of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] like Figure 1 , Figure 2 , Figure 3 As shown, an automatic argon arc welding machine includes a machine body 1. A column 2 is arranged on the machine body 1. A sliding seat 3 is slidably arranged on the column 2. An obliquely arranged welding head 4 is arranged on one side of the sliding seat. When in use, a welding wire can be added near the position of the welding head 4 to ensure the welding effect. This is a prior art, so it is not repeated.

[0024] Correspondingly, a cylinder 1 5 is connected to the top of the sliding seat 3. The cylinder 1 5 can drive the sliding seat 3 to move up and down, so that the sliding seat 3 can move up and down to the position where welding is required. In addition, a cylinder 2 6 is fixedly arranged on the sliding seat 3. The output position of the cylinder 2 6 corresponds to a positioning seat 7 that can slide on the sliding seat 3. Among them, the welding head 4 is connected to the positioning seat 7, and through the push of the cylinder 2 6, the welding head 4 can be changed in position at a horizontal position, thereby ensuring that the welding head 4 can reach the position where welding is required.

[0025] The machine body 1 is provided with a bracket 8. A rotating drum 9 is provided in the middle of the bracket 8. A mounting groove 10 for mounting a circular pipe that has been spot-welded is provided in the middle of the rotating drum 9. The circular pipe is composed of two circular workpieces, which have been preliminarily fixed by spot welding when placed in the mounting groove 10.

[0026] In addition, a corresponding nozzle 11 can be arranged at the position of the welding head 4, and the nozzle 11 can spray argon gas to form a protective film. This is a prior art and will not be described in detail.

[0027] The rotating drum 9 is provided with a strap 12. One end of the strap 12 is fixed to the rotating drum 9, and the other end is freely provided. After the corresponding round pipe is placed in the installation groove 10, the round pipe is tightened by one end of the strap 12, and the two ends of the strap 12 are fixed to each other, which can be in the form of a buckle or a bundle. Under the above arrangement, the round pipe entering the installation groove 10 is in a fixed state, and can rotate with the rotation of the rotating drum 9.

[0028] A driving motor is connected to the bottom of the rotating drum 9 to drive the rotating drum 9 to rotate.

[0029] Overall working process:

[0030] 1. Place the corresponding round pipe into the installation groove 10 and fix it with the strap 12. After that, the cylinder 1 5 drives the sliding seat 3 to move down to the position where welding is required, and the cylinder 2 6 moves the welding head 4 to the position where welding is required, and the work before welding is completed;

[0031] 2. The welding head 4 is heated to melt the welding wire and attach it to the position where welding is required. After that, the driving motor is operated to drive the rotating drum 9 to rotate. After one rotation, the position where welding is required is completely welded to achieve a better welding effect.

[0032] like Figure 1 , Figure 3 , Figure 4 As shown, the present application further has a connecting rod 13 disposed on one side of the sliding seat 3. The connecting rod 13 is T-shaped, and a driving rod 14 is connected to the end of the connecting rod 13. Gears 15 are meshed on both sides of the driving rod 14. A gear bar 16 is meshed on one side of the gear 15. A baffle 17 is connected to the bottom of the gear bar 16. At the position corresponding to the baffle 17, a slide groove 18 is further disposed on the body 1 for the baffle 17 to slide in the longitudinal direction. A slider (not shown in the figure) may be disposed on the baffle 17 corresponding to the slide groove 18, and the slide groove 18 and the slider are T-shaped.

[0033] Under the above arrangement, when the sliding seat 3 moves downward under the action of the cylinder 15, the driving rod 14 moves downward, and then rotates clockwise, so that the gear rod 16 moves upward. Driven by the gear rod 16, the baffle 17 moves upward to the shielding welding position. During the welding process, since welding generates a large amount of light and heat, the welding process has a great stimulation and damage to the eyes of the operator. The above welding preparation is performed so that the baffle 17 shields the entire welding process, achieving a higher safety level.

[0034] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
