Obviously, the described embodiments are only some embodiments of this application, not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application.

[0038] When welding seamless titanium tubes, manual welding requires maintaining a proper distance between the welding torch and the weld seam, making it difficult to guarantee weld quality. Existing welding equipment automates welding by using a rotatable fixing ring on the outside of the seamless titanium tube to rotate it at a uniform speed. However, this method is not suitable for long seamless titanium tubes and is difficult to load. To solve the above problems, this application provides a seamless titanium tube welding machine that simplifies the loading process and is suitable for welding seamless titanium tubes of various lengths.

[0039] like Figure 1 , Figure 2 and Figure 3As shown in the figure, this application provides a titanium seamless tube welding machine, including a workbench 100. The workbench 100 is characterized by having: a mounting plate 200, with a rotating assembly 220 and a motor 210 respectively mounted on both sides of the mounting plate 200; the rotating assembly 220 for fixing one end of the titanium seamless tube, and the motor 210 for driving the rotating assembly 220 to rotate the titanium seamless tube; and a welding frame 400 for mounting a welding head 410, which is used to weld two titanium seamless tubes. The system comprises: several upper fixing frames 300 for mounting upper fixing members 310; several lower fixing frames 500 for mounting lower fixing members 510; the upper fixing members 310 contact the upper side of the seamless titanium tube, and the lower fixing members 510 contact the lower side of the seamless titanium tube to fix it; a welding frame 400, upper fixing frames 300, and lower fixing frames 500 are all disposed on the side of the mounting plate 200 with a rotating plate 221, and are slidably connected to the worktable 100 along the axis of the seamless titanium tube. In this embodiment, four lower fixing frames 500, two upper fixing frames 300, and one welding frame 400 are provided. Two seamless titanium tubes to be welded are respectively fixed by the two lower fixing frames 500 and the one upper fixing frame 300. The middle position is welded by a welding frame 400 disposed between the two upper fixing frames 300. The rotating component 220 drives the seamless titanium tube to rotate at a uniform speed. In other embodiments, multiple welding frames 400 can also be provided to weld multiple seamless titanium tubes.

[0040] Specifically, such as Figure 4 As shown, the rotating assembly 220 includes a rotating plate 221. The motor shaft 211 of the motor 210 passes through the mounting plate 200 and is connected to the rotating plate 221. A horizontal groove 225 is provided on the rotating plate 221. End plates 227 are respectively provided at both ends of the groove 225. A bidirectional lead screw 223 is provided in the groove 225 along the direction of the groove 225. The two ends of the bidirectional lead screw 223 are rotatably connected to the end plates 227. The two ends of the bidirectional lead screw 223 are respectively threaded to sliders 224. The two sliders 224 slide in the groove 225 respectively, and the sliders 224 are away from the groove 225. A clamping block 222 is connected to the inner side, and two clamping blocks 222 are used to clamp the seamless titanium tube. One end of the bidirectional lead screw 223 passes through the end plate 227 and is connected to a handle 226, so as to drive the bidirectional lead screw 223 to rotate through the handle 226. The motor 210 drives the rotating assembly 220 to rotate the seamless titanium tube. The clamping surface of the clamping block 222 is a V-shape with opposite openings. An anti-slip pad is provided on the clamping surface, which can increase the friction between the outer wall of the seamless titanium tube and the clamping block 222, so as to reduce the slippage of the seamless titanium tube when rotating, thereby improving the stability of the seamless titanium tube when rotating. The anti-slip pad can be a rubber pad.

[0041] Specifically, such as Figure 9As shown, the worktable 100 has two symmetrical first slide rails 110 and two second slide rails 120 arranged along the axial direction, with the first slide rails 110 located outside the second slide rails 120. The two legs of the welding frame 400 and the upper fixed frame 300 slide within the two first slide rails 110, and the two legs of the lower fixed frame 500 slide within the two second slide rails 120, respectively. This allows the welding frame 400 and the upper fixed frame 300 to be located outside the lower fixed frame 500, and the lower fixed frame 500 to move through the welding frame 400 and the upper fixed frame 300.

[0042] Specifically, such as Figure 7 As shown, the welding head 410 is connected to the welding frame 400 via a vertically arranged electric telescopic rod 420. The electric telescopic rod 420 extends and retracts to adjust the distance between the welding head 410 and the seamless titanium tube. The welding head 410 is connected to a power source via a wire 430.

[0043] Specifically, such as Figure 10 As shown, a side plate 441 is fixed outward on the outer side of the support leg of the welding frame 400. The side plate 441 is set along the upper side of the workbench 100. The side plate 441 is threadedly connected to a vertically set screw 440. The screw 440 is rotated so that the front end of the screw 440 abuts against the upper side of the workbench 100 to fix the welding frame 400 and the workbench 100 and prevent the welding frame 400 from moving during welding.

[0044] Specifically, such as Figure 5 and Figure 6 As shown, the upper fixing frame 300 includes a top frame 301 at the top and side frames 302 on both sides; the two sides of the upper fixing member 310 are slidably connected to the side frames 302 on both sides respectively, the upper end of the upper fixing member 310 is rotatably connected to the threaded rod 320, the threaded rod 320 is rotatably connected to the upper fixing member 310 through the rotating head 322, the threaded rod 320 passes through the top frame 301 and is threadedly connected to the top frame 301, rotating the threaded rod 320 can change the distance between the upper fixing member 310 and the seamless titanium tube, and the end of the threaded rod 320 is provided with a handle 321 to facilitate the operator to rotate the threaded rod 320.

[0045] Specifically, such as Figure 5 and Figure 8 As shown, the opposing surfaces of the upper fixing member 310 and the lower fixing member 510 are respectively arc surfaces that fit the outer diameter of the titanium seamless tube; a number of rollers 311 arranged in the same direction as the titanium seamless tube are provided in the arc surface to reduce the friction between the titanium seamless tube and the upper fixing member 310 and the lower fixing member 510 when the titanium seamless tube rotates.

[0046] The embodiments of this application allow for adjustment of the welding position of the seamless titanium tube through the movable welding frame 400, upper fixed frame 300, and lower fixed frame 500, which is suitable for welding seamless titanium tubes of different lengths. Furthermore, during material loading, the welding frame 400 and upper fixed frame 300 can be moved to one side, and the seamless titanium tube to be welded can be placed on the lower fixed member 510, simplifying the material loading process and making it convenient for workers to use.

[0047] The workflow of a titanium seamless tube welding machine provided in this application embodiment is as follows: The welding frame 400 and upper fixed frame 300 are moved to one side; the lower fixed frame 500 is moved to a suitable position according to the length of the titanium seamless tube to be welded; several sections of titanium seamless tube to be welded are placed on the lower fixed member 510; then, the titanium seamless tubes near the mounting plate 200 are fixed by the rotating assembly 220, aligning the ends of adjacent titanium seamless tube sections; the upper fixed frame 300 is moved to a suitable position; and the welding frame 400 is moved to the position of adjacent titanium seamless tube sections. The tubes are fixed together by screws 440, and then the ends of the two adjacent seamless titanium tubes are welded together by welding head 410. After the ends of the two adjacent seamless titanium tubes are welded together, the motor 16 is started to drive the rotating component 220 to rotate, and the seamless titanium tubes are rotated at the same time. At this time, the welding head 410 can evenly weld the ends of the two adjacent seamless titanium tubes. When the seamless titanium tubes rotate, the roller 311 will rotate together to support the seamless titanium tubes. After the welding is completed, the seamless titanium tubes and the rotating component 220 are separated, and the welded seamless titanium tubes are removed.

[0048] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
