Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a protective shielding for titanium alloy welding. Background Technology

[0002] Welding is a manufacturing process and technology that permanently joins metals or other thermoplastic materials by heating, pressurizing, or a combination of both. Argon arc welding is widely used in the field of alloy welding. During argon arc welding, it is necessary to isolate the weld from air to prevent oxidation, so a protective shield is required.

[0003] The existing welding protective shield uses a metal protective shell with a connector at the top. The pipe for inputting argon gas is connected to the connector, and then argon gas can be input through the protective shell. The argon gas is then dispersed by the guide plate inside the protective shell and sealed by the external sealing gasket. At this point, the welding torch can be used to weld titanium alloy.

[0004] However, the guide plates in the welding protection shielding chamber are all installed and sealed, making it difficult to open the mesh and partition plates inside the chamber. Forcing the chamber open can easily damage or render the shielding unusable, resulting in high replacement costs. Therefore, this invention proposes a titanium alloy welding protection shielding system. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art where the guide plates in the welding protection shielding gas chamber are already installed and sealed, making it difficult to adjust and open the mesh and partition plates inside the gas chamber. This requires a forceful method to open the gas chamber, which can easily lead to damage or scrapping of the shielding and result in high replacement costs. Therefore, this invention proposes a titanium alloy welding protection shielding method.

[0006] The technical solution of this utility model: A titanium alloy welding protective cover includes a cover body. An injection port is fixedly connected to the outside of the cover body, communicating with the inside of the cover body. The cover body is arc-shaped with an internal opening. A guide plate is embedded inside the cover body. A mesh abuts against the guide plate and the side opposite to the cover body. The mesh has ten layers with partitions between each pair. A positioning nut abuts against the side of the guide plate away from the inside of the cover body. A positioning bolt is rotatably connected inside the positioning nut. The positioning bolt passes through the cover body and is rotatably connected inside the cover body. A positioning screw is fixedly connected to the outside of the cover. A sealing gasket is embedded in the outside of the positioning screw, and the sealing gasket is U-shaped and wrapped around the outside of the cover. A support frame is fixedly connected to the outside of the cover. A clamping ring is provided on the outside of the support frame. The clamping ring is U-shaped. Rotating components are provided on both sides of the clamping ring and the support frame.

[0007] Optionally, the rotating assembly includes a rotating plate, which is rotatably connected to both sides of the clamping ring and the support frame, and the rotating plate and the support frame are slidably connected to the clamping ring and the rotating plate by fastening bolts.

[0008] Optionally, the fastening bolt is externally rotatably connected to a fastening nut, and the fastening nut has multiple sets abutting against the rotating plate and the support frame, as well as the clamping ring and the support frame on the side away from their opposite sides.

[0009] Optionally, a sealing sleeve is slidably connected inside the clamping ring, and the top of the sealing sleeve is arranged in an open and closed shape with multiple sets of circumferential arrays.

[0010] Optionally, a sealing nut is rotatably connected to the outside of the positioning screw, and the sealing nut is located on the outside of the positioning screw near the sealing gasket.

[0011] Optionally, a gasket is slidably connected to the outside of the positioning screw near the sealing nut, with one side of the gasket abutting against the side of the sealing gasket away from the cover, and the side of the gasket away from the sealing gasket abutting against the side of the sealing nut.

[0012] In summary, this application includes at least one of the following beneficial technical effects: This invention uses a positioning bolt that passes through the cover and is rotated and installed inside the positioning nut.

[0020] like Figure 1 , Figure 2 and Figure 5As shown, this utility model proposes a titanium alloy welding protective shield, comprising a shield body 1. An injection port 11 is fixedly connected to the outside of the shield body 1, allowing argon gas to be injected into the inside of the shield body 1. The injection port 11 communicates with the inside of the shield body 1. The shield body 1 is arc-shaped with an internal opening. A guide plate 2 is embedded inside the shield body 1. A mesh 16 abuts against the side of the guide plate 2 opposite to the shield body 1. The mesh 16 has ten layers, with partitions between each pair. The ten layers of mesh 16 can fully atomize the argon gas. A positioning nut 3 abuts against the side of the guide plate 2 away from the inside of the shield body 1. The positioning nut 3 can hold the guide plate 2 in place inside the shield body 1. A positioning bolt 4 is rotatably connected inside the positioning nut 3. The sealing gasket 12 can position the positioning nut 3 inside the cover 1. The positioning bolt 4 passes through the cover 1 and is rotatably connected inside the cover 1. The positioning screw 13 is fixedly connected to the outside of the cover 1. The positioning screw 13 is fixedly connected to the outside of the cover 1. The sealing gasket 12 is embedded in the outside of the positioning screw 13. The sealing gasket 12 can be fixed by the positioning screw 13. The sealing gasket 12 is wrapped in a "U" shape around the outside of the cover 1. The shape of the sealing gasket 12 makes the sealing gasket 12 more airtight. The support frame 8 is fixedly connected to the outside of the cover 1. The support frame 8 is provided with a clamping ring 6. The clamping ring 6 is set in a "U" shape. The clamping ring 6 can be connected to the welding gun. Rotating components are provided on both sides of the clamping ring 6 and the support frame 8.

[0021] For further details, please refer to Figure 1 and Figure 2 The rotating assembly includes a rotating plate 7, which is rotatably connected to both sides of the clamping ring 6 and the support frame 8. Rotating the rotating plate 7 on both sides of the clamping ring 6 and the support frame 8 adjusts the angle of the clamping ring 6, allowing it to adapt to the angle of the welding torch tip. The rotating plate 7 and the support frame 8 are slidably connected to the clamping ring 6 and the rotating plate 7 internally by fastening bolts 9. Fastening nuts 10 are rotatably connected to the outside of the fastening bolts 9. Rotating the fastening nuts 10 outside the fastening bolts 9 allows the clamping ring 6 and the rotating plate to be adjusted. 7 and support frame 8 are interconnected. There are multiple sets of fastening nuts 10 abutting against the rotating plate 7 and support frame 8, as well as the clamping ring 6 and support frame 8 on the opposite side away from them. The fastening nuts 10 can be tightened or loosened so that the angle of the clamping ring 6 matches the nozzle of the welding gun. A sealing sleeve 5 is slidably connected inside the clamping ring 6. The sealing sleeve 5 can wrap around the outside of the nozzle of the welding gun. The top of the sealing sleeve 5 is set in an opening and closing shape with multiple sets of circumferential arrays. The opening of the sealing sleeve 5 allows it to accommodate more welding gun nozzles.

[0022] For further details, please refer to Figure 1 , Figure 3 and Figure 4A sealing nut 14 is rotatably connected to the outside of the positioning screw 13. By rotating the sealing nut 14 outside the positioning screw 13, the positioning screw 13 can be brought closer to the sealing gasket 12, thereby fixing the sealing gasket 12. The sealing nut 14 is located outside the positioning screw 13 near the sealing gasket 12. A washer 15 is slidably connected to the outside of the positioning screw 13 near the sealing nut 14. The washer 15 can increase the contact surface of the sealing nut 14, thereby preventing the sealing nut 14 from slipping. One side of the washer 15 abuts against the side of the sealing gasket 12 away from the cover 1, and the side of the washer 15 away from the sealing gasket 12 abuts against the side of the sealing nut 14. The washer 15 abutting against the opposite side of the sealing gasket 12 and the sealing nut 14 can tightly connect the cover 1 and the sealing gasket 12.

[0023] In this embodiment, when welding, the fastening nut 10 is first loosened by rotating it from the outside of the fastening bolt 9. Then the welding gun head can be put inside the clamping ring 6. If the gun head is small, the welding gun head can be inserted into the sealing sleeve 5 first, and then the sealing sleeve 5 can be inserted into the clamping ring 6. Then the clamping ring 6, rotating plate 7 and support frame 8 can be tightened and fixed by tightening the fastening nut 10. Then the cover 1 can be installed on the outside of the gun head by fitting it in. Then the welding operation can be performed.

[0024] Before welding, the argon gas output head needs to be placed outside the filling port 11 so that the argon gas can be input into the inside of the cover 1 for welding. When the argon gas is input, the argon gas will pass through the guide plate 2, which will disperse the argon gas and distribute it at the nozzle of the welding gun so that the nozzle can perform the welding operation.

[0025] During welding, the sealing gasket 12 can seal the outside of the cover 1 to prevent argon gas from leaking out of the cover 1 and ensure that argon gas is not wasted. After the sealing gasket 12 has been used for a period of time, wear will inevitably occur between the sealing gasket 12 and the contact position. At this time, the sealing nut 14 can be rotated to remove the sealing nut 14 and the gasket 15 from the outside of the positioning screw 13. In this way, the sealing gasket 12 can be removed from the outside of the cover 1 for replacement. The new sealing gasket 12 is installed on the outside of the positioning screw 13. Then, the gasket 15 and the sealing nut 14 are successively put on the outside of the positioning screw 13, thereby fixing the sealing gasket 12 to the outside of the cover 1.

[0026] After a period of use, in order to ensure the air permeability of the deflector plate 2 and the mesh 16 and to clean the disassembled mesh 16, the positioning bolt 4 can be rotated to disengage the positioning bolt 4 from the inside of the positioning nut 3. Then the deflector plate 2 can be easily removed from the inside of the cover 1 for replacement.

[0027] It should be noted that this device uses a positioning bolt 4 to pass through the cover 1 and rotate to install the positioning bolt 4 inside the positioning nut 3. This allows the positioning nut 3 to abut against one side of the guide plate 2, thereby stably installing the guide plate 2 inside the cover 1. When replacement is needed, simply remove the positioning bolt 4 from the cover 1 and the positioning nut 3. This allows the guide plate 2 and the mesh 16 to be disassembled and replaced, improving the convenience of disassembling and replacing the mesh 16 and reducing replacement costs.

[0028] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
