[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] It should be noted that 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. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0036] like Figure 1 , 2As shown in Figure 5, a disc welding machine is provided with a frame 1, a positioning unit 2 and a welding unit 3 are provided on the frame 1, a pressing unit 4 is also provided on the frame 1, and the pressing unit 4 includes a pressing plate 41, and the pressing plate 41 is connected to a pressing lifting driver 42, and a pressing plate channel 411 is provided in the middle of the pressing plate 41.

[0037] Specifically, the pressing and lifting driver 42 can drive the pressing plate 41 to move up and down. When in use, the operator places the disc to be welded on the positioning unit 2 to ensure that the position of the disc is accurate. The pressing unit 4 starts working, and the pressing and lifting driver 42 drives the pressing plate 41 to move downward until the pressing plate 41 is close to the top of the disc. A pressing plate channel 411 is provided in the middle of the pressing plate 41, and the welding unit 3 can pass through the pressing plate channel 411 without obstacles to directly weld the inner circle of the disc. When the welding unit 3 completes the welding, the pressing and lifting driver 42 drives the pressing plate 41 to rise again, and the operator can easily take out the disc that has been welded. By setting the pressing unit 4, it can be ensured that the disc will not be displaced or misplaced during the welding process. The pressing plate 41 is set horizontally to ensure that each part of the disc is subjected to uniform pressure, thereby ensuring the uniformity of welding of each part of the disc, thereby ensuring the welding quality and stability. In addition, the operator only needs to place the disc on the positioning unit 2 and move the pressing plate 41 downward, while the positioning unit 2 does not move and the disc does not move, thereby avoiding misalignment of the layers when the disc moves.

[0038] like Figure 3 , 4 As shown, the positioning unit 2 includes a positioning support body 21 and a positioning ring 22 , and the positioning ring 22 is arranged in the middle position of the positioning support body 21 .

[0039] Specifically, the positioning support 21 provides a stable support platform, and the positioning ring 22 is placed in the middle of the disc to play a positioning role. When the operator places the disc on the positioning support 21, the positioning ring 22 ensures that the center of the disc is accurately aligned with the welding point, avoiding welding quality problems caused by position offset during the welding process.

[0040] like Figure 5 , 6 As shown, the pressing unit 4 further includes a pressing rotating disk 43 , which is rotatably mounted on the pressing disk 41 , and the positioning unit 2 is rotatably mounted on the frame 1 , and the positioning unit 2 is connected to a positioning rotating driver 23 .

[0041] Specifically, the positioning rotation driver 23 can drive the positioning unit 2 to rotate, and the pressing and lifting driver 42 can drive the pressing rotating disk 43 to move up and down. When the pressing rotating disk 43 presses the disc, the positioning rotation driver 23 drives the positioning unit 2 to rotate, and the disc and the pressing rotating disk 43 rotate together. The welding unit 3 remains in a fixed position to achieve continuous and uniform welding of the inner circle of the disc, thereby greatly improving the welding efficiency. In addition, during the rotation welding process, each part of the inner circle of the disc can be evenly contacted with the welding tool, thereby ensuring the consistency and stability of the welding quality.

[0042] like Figure 4 , 5 As shown, a baffle 44 is disposed on the pressing plate 41 , a baffle channel 441 is disposed in the middle of the baffle 44 , and a diameter of the baffle channel 441 is smaller than a diameter of the pressing plate channel 411 .

[0043] Specifically, during the disc welding process, an inert gas (such as argon) is usually used for protection to prevent oxygen in the air from affecting the welding quality. The diameter of the baffle channel 441 is smaller than the diameter of the pressing plate channel 411, which can effectively prevent the inert gas from overflowing.

[0044] like Figure 1 , 2 As shown, the welding unit 3 includes a welding position adjuster 31 and a welding gun 32 arranged on the welding position adjuster 31 , and the welding position adjuster 31 includes a welding horizontal adjuster 311 and a welding vertical adjuster 312 .

[0045] Specifically, the welding horizontal adjuster 311 and the welding vertical adjuster 312 can be linear modules or rolling screws. By setting the welding position adjuster 31, the position of the welding gun 32 can be flexibly adjusted as needed to meet the welding requirements of discs of different specifications and types.

[0046] like Figure 5 , 6 As shown, a pressing rotating disk pressure plate 431 is fixedly provided at the bottom of the pressing rotating disk 43 , a pressure plate channel 432 is provided in the middle of the pressing rotating disk pressure plate 431 , and the diameter of the pressure plate channel 432 is larger than the diameter of the positioning ring 22 and smaller than the diameter of the positioning support body 21 .

[0047] Specifically, when the pressing lifting driver 42 drives the pressing plate 41 to move downward, the pressing rotating plate 43 approaches the disc, and at the same time, the pressing rotating plate pressing plate 431 presses the positioning support body 21. Since the diameter of the pressing plate channel 432 is larger than the diameter of the positioning ring 22 but smaller than the diameter of the positioning support body 21, the pressing rotating plate pressing plate 431 is sleeved on the positioning ring 22, and at the same time, the pressing rotating plate pressing plate 431 partially overlaps with the positioning support body 21, playing a supporting role, ensuring that the disc keeps stable rotation between the pressing rotating plate 43 and the positioning support body 21, which helps to reduce welding defects and improve the qualified rate of products.

[0048] like Figure 1 , 2 As shown, there are two pressing and lifting drivers 42 , which are respectively located on both sides of the positioning unit 2 , and the pressing unit 4 is fixedly mounted on the pressing and lifting drivers 42 . The pressing unit 4 is located above the positioning unit 2 .

[0049] Specifically, before welding, the disc is placed on the positioning unit 2. Since the pressing unit 4 is located above the positioning unit 2, it moves downward through two pressing lifting drivers 42 so that the pressing unit 4 presses on the disc to avoid misalignment caused by the movement of the disc.

[0050] like Figure 1 , 2 As shown, the welding unit 3 is fixedly arranged on the pressing and lifting driver 42 .

[0051] Specifically, when the pressing and lifting driver 42 moves downward, the welding unit 3 will also move downward accordingly. When the pressing rotating disk 43 presses the disc under the drive of the pressing and lifting driver 42 and rotates with the positioning unit 2, the welding gun 32 can maintain its relative position with the disc unchanged and continue to weld the disc, thereby achieving continuous and uniform welding while the disc rotates, thereby improving welding efficiency and quality.

[0052] like Figure 4 , 5 As shown, the pressing plate 41 , the pressing rotating plate 43 , the baffle 44 , and the pressing rotating plate pressure plate 431 together form a welding isolation cavity 45 .

[0053] Specifically, the pressing disc 41, the pressing rotating disc 43, the pressing rotating disc pressure plate 431 and the baffle 44 work together during the rotational welding process. The pressing rotating disc 43 not only realizes the rotational welding requirements of the disc, but also the cavity setting in the middle, together with the pressing disc 41, the pressing rotating disc pressure plate 431 and the baffle 44, constitutes a welding isolation chamber 45. Before welding begins, the welding isolation chamber 45 is filled with an inert gas (such as argon) that can effectively isolate the welding area from the external environment, providing a stable and pure environment for welding, thereby reducing the risk of defects such as oxidation and pores during welding. At the same time, the welding isolation chamber 45 can also effectively prevent the sparks and spatters generated during the welding process from causing harm to the operator. The sparks and spatters are confined in a relatively closed space, which greatly reduces their potential threats to the operator and improves operational safety.

[0054] The present application discloses a disc welding machine, which is provided with a frame 1, on which a positioning unit 2, a welding unit 3, and a pressing unit 4 are provided. By providing the pressing unit 4, it can be ensured that the disc will not be displaced or misaligned during the welding process. The pressing plate 41 is arranged horizontally to ensure that each part of the disc is subjected to uniform pressure, thereby ensuring the uniformity of welding of each part of the disc, thereby ensuring the welding quality and stability; the operator only needs to place the disc on the positioning unit 2, and the pressing plate 41 moves downward, while the positioning unit 2 does not move and the disc does not move, thereby avoiding misalignment of each layer when the disc moves; the positioning ring 22 is provided to ensure that the center of the disc is accurately aligned with the welding point; the positioning rotary drive 23, the pressing unit 41 are provided The rotating disk 43 realizes continuous and uniform welding of the inner circle of the disk; the pressing disk 41, the pressing rotating disk 43, the pressing rotating disk pressure plate 431 and the baffle 44 together constitute a welding isolation chamber 45. The welding isolation chamber 45 is filled with inert gas, which can effectively isolate the welding area from the external environment, providing a stable and pure environment for welding, thereby reducing the risk of defects such as oxidation and porosity during the welding process; the welding isolation chamber 45 can also effectively prevent the sparks and spatters generated during the welding process from causing harm to the operator. The sparks and spatters are confined in a relatively closed space, which greatly reduces their potential threat to the operator and improves operational safety.
