Description

Technical Field

[0001] The utility model relates to the technical field of welding auxiliary tools, in particular to a tungsten pole angle conversion welding auxiliary tool. Background Art

[0002] Pipe-to-pipe all-position argon arc automatic welding, as a kind of tungsten inert gas argon arc automatic welding (abbreviated as "TIG automatic welding"), is an arc welding method that uses pure tungsten or activated tungsten (such as thoriated tungsten, cerium tungsten, etc.) as a non-melting electrode and adopts inert gas argon (pure Ar) as a shielding gas. It can produce high-quality welds and is simple to operate. It is suitable for various types of welding processes and is commonly used for welding high-temperature and corrosion-resistant metal materials such as stainless steel, nickel alloys and titanium alloys.

[0003] The existing pipe-to-pipe all-position argon arc automatic welding machine can only realize the welding of circular pipe butt welds (i.e., PA position), and cannot realize the welding of casing or tube sheet welds (i.e., PB position). For the circumferential welds of casing or tube sheet, we always hope that it can be welded by rotating the workpiece or the welding machine gun head (especially when the workpiece length exceeds 1m). However, for casing or tube sheet welds where the workpiece cannot be rotated, the existing technology cannot rely on conventional positioning fixtures to realize the welding machine gun head rotation welding, and most of the workpieces are manually assisted to rotate to realize the welding of the workpiece, which not only occupies a large amount of manpower and material resources and has low production efficiency, but also cannot effectively ensure the consistency of weld appearance. There are also problems such as inconvenient operation, inaccurate positioning, and potential safety hazards, which seriously affect the welding effect and efficiency.

[0004] For the circumferential welds of the above-mentioned casing or tube sheet, when using a tube-to-tube all-position argon arc automatic welding machine for welding, the tungsten electrode angle must be changed (i.e., the welding angle is changed) to achieve welding. At the same time, precise control of the tungsten electrode angle has an important impact on the welding quality of small parts. However, the tungsten electrode fixing device of the welding machine is a single fixing method, which can only achieve welding in the PA position, and has limitations in the convenience and accuracy of angle adjustment.

[0033] A locking mechanism, which is arranged on the fixed seat 1, and the locking mechanism is detachably connected to the rotating seat 2 for fixing the rotating seat 2.

[0034] In this embodiment, by setting the fixed seat 1 and the rotating seat 2, the fixed seat 1 is connected to the welding machine, and then through the function that the rotating seat 2 can rotate on the fixed seat 1. After the rotating seat 2 fixes the tungsten electrode 6 through the installation component, the angle change of the tungsten electrode 6 can be realized. The operation is convenient, the angle change of the tungsten electrode 6 is flexible, the welding precision is improved, and more flexible welding requirements are met.

[0035] In an exemplary embodiment, a rotating shaft 3 is provided on the fixed seat 1, an avoidance groove 301 for inserting the tungsten electrode 6 is opened on the rotating shaft 3, and the rotating seat 2 is arranged on the rotating shaft 3.

[0036] In this embodiment, by setting the rotating shaft 3 on the fixed seat 1, the rotating seat 2 can be fixed, and the rotating seat 2 is rotatably connected to the fixed seat 1. Installing the rotating seat 2 on the rotating shaft 3 can realize the function of the rotating seat 2 rotating, thereby adjusting the angle of the tungsten electrode 6.

[0037] Exemplarily, in this embodiment, a first indicating part 9 is provided on the fixed seat 1, a second indicating part 10 is provided on the rotating seat 2, and the rotation angle of the rotating seat 2 is 90° - -90°. The first indicating part 9 in this embodiment can be a first indicating needle provided on the fixed seat 1, or a first indicating groove opened on the fixed seat 1, while the second indicating part 10 is a plurality of second indicating needles or a plurality of second indicating grooves opened on the rotating seat 2, and the included angle between adjacent second indicating needles or second indicating grooves is equal.

[0038] It should be noted that, in this embodiment, the rotating seat 2 is sleeved on the rotating shaft 3, the outer contour of the rotating seat 2 close to the fixed seat 1 is an arc surface, and the second indicating part 10 is opened at the top of the rotating seat 2 and is also arc-shaped. When the first indicating part 9 aligns with one of the second indicating needles or one of the second indicating grooves, it means that the rotating seat 2 is at a fixed angle at this time. Exemplarily, as Figure 3 and Figure 4 shown, Figure 3 is a schematic diagram of the rotating seat 2 not rotating.Figure 4 It is a schematic diagram of the rotating base 2 rotating by a certain angle, and the rotation angle is determined by the first indicating portion 9 and the second indicating portion 10.

[0041] Exemplarily, the mounting assembly includes a mounting hole 203 and a first fastener 7. The mounting hole 203 is opened on the side wall of the fixing portion 202 and extends into the avoiding groove 301. The first fastener 7 is detachably connected to the side wall of the connecting portion 201, and one end of the first fastener 7 can enter the avoiding groove 301 and abut against the tungsten electrode 6. During installation, the tungsten electrode 6 is inserted into the mounting hole 203 until it reaches the avoiding groove 301, and then the first fastener 7 is screwed in. The end portion of the first fastener 7 abuts against the tungsten electrode 6, so that the tungsten electrode 6 is tightly fixed in the mounting hole 203 to prevent the tungsten electrode 6 from coming out. The first fastener 7 in this embodiment can adopt fasteners such as bolts, and the axis of the first fastener 7 is perpendicular to the axis of the rotating shaft 3.

For example, it is opened on the side wall of the fixing portion 202 and can enter the mounting hole 203 to fix the tungsten electrode 6. The mounting hole 203 in this embodiment extends into the avoiding groove 301 mainly to increase the length of the tungsten electrode 6 inside the rotating base 2, enhance the fixing effect of the tungsten electrode 6, and prevent the fixing section of the tungsten electrode 6 from being too short to cause the tungsten electrode 6 to be not firmly fixed.

[0043] It should also be noted that in this embodiment, due to the setting position of the first fastener 7, an avoiding groove 301 is opened on the rotating shaft 3, so that there will be no movement interference between the rotating shaft 3 and the tungsten electrode 6 when the rotating base 2 rotates, ensuring that the rotating base 2 can realize the rotating function.

[0044] In an exemplary embodiment, a fixing hole 101 is opened on the fixing base 1. The fixing hole 101 is detachably connected to a mounting rod 4 for connecting with a welding machine.

The steps in this embodiment are carried out after the angle of the rotating base 2 is adjusted and fixed.

[0046] Exemplarily, when the mounting rod 4 is mounted on the welding machine, the free end of the mounting rod 4 is inserted into the positioning hole on the welding machine, and a bolt enters the welding machine from the side, and the end of the bolt abuts against the mounting rod 4 to fix the mounting rod 4 to the welding machine.

[0048] In an exemplary embodiment, the locking mechanism includes a locking member 8, and the locking member 8 can pass through the fixed seat 1 and be detachably connected to the rotating shaft 3.

[0049] In this embodiment, after determining the angle of the rotating seat 2, the locking member 8 is installed from the bottom, and the locking member 8 is connected to the rotating shaft 3 to fix the rotating shaft 3, preventing the rotating shaft 3 from rotating again, and then fixing the rotating seat 2, ensuring the stability of the rotating seat 2 and the welding effect.

[0050] Exemplarily, in this embodiment, the locking member 8 is a bolt, and a locking hole threadedly connected to the locking member 8 is opened at the bottom of the rotating shaft 3. When the locking member 8 cooperates with the locking hole, the fixing of the rotating shaft 3 can be achieved.
