[0035] Furthermore, the mounting assembly 204 includes a positioning slot 204a provided at one end of the rotating rod 202b, a vertical support rod 204b provided at the top of the positioning slot 204a, a mounting block 204e provided on the vertical support rod 204b, and mounting parts 204f provided on both sides of the mounting block 204e. The mounting assembly 204 is clamped on the rotating rod 202b through the positioning slot 204a on the mounting assembly 204. Because the rotating rod 202b is at the center position of the circle inside the guide tube body 103, the positioning slot 204a clamped on the rotating rod 202b is also at the same position for installation and positioning.

[0036] Furthermore, an angled support rod 204c is provided at the bottom of the positioning slot 204a, and a baffle 204d is provided at the bottom of the angled support rod 204c, and the baffle 204d is connected to the guide tube body 103.

[0037] During use, when the guide tube body 103 is fixed and welded, the guide tube body 103 is lifted and placed on the clamping assembly 301, and the block 301f on the clamping assembly 301 cooperates with the supporting base 301b to clamp and fix the guide tube body 103, so that the guide tube body 103 can be fixed on the clamping assembly 301, and the movable plate 201c is moved to move along the movable slot 201d, so that the cross column 201b is adjusted with the fixing plate 201a, and the fixing assembly 203 is inserted into the guide tube body 103, and the electric push rod 203g inside the fixing assembly 203 starts to move backward, so that the linkage rod 203e starts to rotate, and at the same time, the top plate 203d starts to expand upward, and the slider 203b cooperates with the expansion of the top plate 203d on the cross slide 203a. The top plate 203d is moved, and the expansion angle of the top plate 203d is adjusted through the rotating shaft 203c, so that the top plate 203d is completely fitted on the inner wall of the guide tube body 103, fitted and fixed, and the inside of the guide tube body 103 is supported, and the motor 202a is rotated to make the rotating rod 202b start to rotate with the cross slide 203a, and the inner wall of the guide tube body 103 is fixed by the fixing component 203, so that the guide tube body 103 also starts to rotate, and at the same time, the guide tube body 103 is welded through the welding component 401. During welding, the fixing component 203 is used to provide internal support to prevent the guide tube body 103 from being deformed during welding. At the same time, the clamping component 301 is used to cooperate during welding, so that the welding can be completed quickly, and the deformation of the guide tube body 103 due to unstable welding during the welding process can be prevented.

[0038] After welding is completed, by connecting the installation component 204 to the guide tube body 103, because the rotating rod 202b is at the middle center position inside the guide tube body 103, the installation component 204 is clamped on the rotating rod 202b, which can ensure that the installation component 204 is also at the center position of the guide tube body 103, and perform rapid positioning welding to prevent deviations from occurring during installation, which may cause the guide tube body 103 to be unable to be installed correctly, and the installation component 204 can be accurately installed in conjunction with the mounting seat preset on the hull, so that the installation of the propeller guide tube body is very fast, convenient and efficient, and quick disassembly can be achieved by removing the installation component 204 from the rotating rod 202b.

[0039] Example 2, reference Figure 1 - Figure 6, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the clamping assembly 301 includes a bottom plate 301a arranged on the operating table 101, a supporting base 301b arranged on the bottom plate 301a, and an auxiliary rotating wheel 301g rotatably arranged inside the supporting base 301b, and the supporting base 301b is supported and fixed by the bottom plate 301a on the operating table 101.

[0040] Compared with Example 1, further, a support plate 301c is provided on the top of the base plate 301a, an electric push rod 301e is provided on the support plate 301c, a pressure rod 301d is provided on the electric push rod 301e, a clamping block 301f is provided at one end of the pressure rod 301d, an auxiliary rotating wheel 301l is provided for the internal rotation of the clamping block 301f, and the electric push rod 301e connected through the support plate 301c works, so that the pressure rod 301d and the clamping block 301f can clamp the outer diameter of the guide tube body 103 to fix the guide tube body 103.

[0041] Furthermore, the auxiliary component 302 includes an auxiliary rod 302a disposed on the bottom plate 301a, and an auxiliary block 302b disposed on the auxiliary rod 302a, and the auxiliary block 302b on the auxiliary rod 302a is used to perform limiting and blocking cooperation when the guide tube body 103 rotates.

[0042] During use, when the guide tube body 103 is clamped and fixed, the segmented guide tube body 103 is lifted and placed on the support base 301b respectively, and the fixing assembly 203 is inserted into the guide tube body 103 for fixing by moving the connecting assembly 201, and at the same time, the electric push rod 301e is moved downward, so that the pressure rod 301d and the block 301f also start to move downward until the outer diameter of the guide tube body 103 is clamped, and the guide tube body 103 is clamped and fixed by the cooperation of the block 301f and the support base 301b, and the guide tube body 103 is welded by the welding assembly 401, and at the same time, the fixing assembly 203 is rotated by the rotating assembly 202. Component 203 starts to rotate with the guide tube body 103, so that the guide tube body 103 starts to rotate and weld. While the guide tube body 103 rotates, the auxiliary rotating wheel 1 301g and the auxiliary rotating wheel 2 301l inside the supporting base 301b cooperate with the rotation of the guide tube body 103 to perform auxiliary rotation, ensuring the smooth rotation of the guide tube body 103, and the rotating guide tube body 103 is assisted and fixed by the auxiliary component 302, so that the guide tube body 103 can be quickly fixed and clamped, and at the same time, the rotation welding of the rotating component 202 and the fixing component 203 is cooperated to ensure the smoothness of the welding and the accuracy of the welding position of the guide tube body 103.

[0043] The remaining structures are the same as those of Example 1.

[0044] Example 3, reference Figure 1 - Fig.10 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: a welding assembly 401 includes a fixed block 401a arranged on the top of the operating table 101, an electric push rod 3 401b arranged on the fixed block 401a, a connecting rod 401c arranged on the electric push rod 3 401b, and a welding head 401d arranged on the connecting rod 401c. The welding position and welding distance can be adjusted by the fixed block 401a on the welding assembly 401 and the electric push rod 3 401b on the fixed block 401a.

[0045] During use, when the guide tube body 103 is welded as a whole, the guide tube body 103 is lifted in sections and placed on the support base 301b, and the clamping block 301f is moved downward by the electric push rod 301e to fix and clamp the guide tube body 103. At the same time, the position of the rotating component 202 and the fixing component 203 is adjusted by moving the connecting component 201, so that the fixing component 203 can be quickly moved to the inside of the guide tube body 103 to fix and support the inner wall of the guide tube body 103. The fixing component 203 can be moved at a uniform speed with the guide tube body 103 by the rotating component 202. The welding is performed by rotating to ensure the quality of welding. At the same time, the support of the fixed component 203 can prevent the guide tube body 103 from being deformed during welding. The auxiliary rotating wheel 1 301g and the auxiliary rotating wheel 2 301l can be used to cooperate and rotate during the rotation welding of the guide tube body 103. At the same time, the welding distance of the welding head 401d can be adjusted through the cooperation of the electric push rod 3 401b and the fixed block 401a to ensure the welding quality of the guide tube body 103. The assembly method is simple and convenient to operate, and deformation caused by welding is avoided during the welding process, so that product quality is guaranteed and production efficiency is improved.

[0046] The guide tube body 103 is precisely fixed by the electric push rod 2 301e and the clamping block 301f, and the positions of the rotating assembly 202 and the fixed assembly 203 are quickly adjusted by the mobile connection assembly 201 to ensure that the fixed assembly 203 can quickly enter the guide tube body 103 for support. The uniform rotation welding of the rotating assembly 202 and the cooperation of the auxiliary assembly 302 ensure the uniformity and stability of the welding and prevent welding deformation. The cooperation of the electric push rod 3 401b and the fixed block 401a allows the welding distance to be precisely adjusted to further improve the welding quality. The entire process simplifies the operation, improves production efficiency and ensures product quality.
