[0024] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0025] The first implementation method:

[0026] Figure 1-4 A high stability jig for welding steel pipes is shown, comprising a mounting seat 1, a plurality of rectangular grooves 2 are provided on the top of the mounting seat 1, a conical plate 3 is inserted into the interior of the rectangular groove 2, during welding, the diameter of the steel pipe placed on the conical plate 3 is smaller than the width of the conical plate 3, so that after processing, the pipe moves downward into the rectangular groove 2, when welding a steel pipe with a diameter equivalent to the width of the mounting seat 1, it is only necessary to use a plurality of rotating frames 10 to fix the ends of the steel pipe, and after welding, it is only necessary to remove all the rotating frames 10 on the steel pipe from the steel pipe, and remove the steel pipe from the mounting seat 1 can be taken off, a pair of fixing frames 4 are fixedly connected to the upper end of the mounting seat 1, a processing motor 5 is fixedly connected to the left end of the fixing frame 4 near the top, a rotating rod 6 is fixedly connected to the output end of the processing motor 5, a plurality of sleeves 7 are rotatably sleeved on the surface of the rotating rod 6, a plurality of plug holes 8 are opened on the surface of the sleeve 7, a plug block 9 is plugged into the plug hole 8, one end of the plug block 9 passes through the plug hole 8 and is inserted into the rotating rod 6, a rotating frame 10 is fixedly connected to the outer end of the sleeve 7, and a lifting rod 11 is threadedly connected to the inner bottom end of the rectangular groove 2.

[0027] This solution can be realized. When in use, after placing several steel pipes with different diameters on different conical plates 3, the position of the corresponding rotating frame 10 above the steel pipe needs to be adjusted according to the diameter of the steel pipe;

[0028] When the diameter of the steel pipe is large, the corresponding rotating frame 10 needs to be rotated counterclockwise upwards. When the diameter of the steel pipe is small, the corresponding rotating frame 10 needs to be rotated clockwise downwards, and the sleeve 7 is fixed by the plug-in block 9, and then the rotating frame 10 is fixed. After several rotating frames 10 are rotated to a suitable position, the processing motor 5 is started, and its output end drives the rotating rod 6 to rotate clockwise, so that the rotating frame 10 rotates downward and presses the steel pipes with different diameters onto the conical plate 3, and finally welding is performed;

[0029] After welding is completed, it is necessary to rotate the lifting rod 11 to move it downward, thereby moving the conical plate 3 downward, and then moving the steel pipe on the conical plate 3 downward and entering the rectangular groove 2, and then continue to process the other compressed steel pipes. By setting the conical plate 3, it is convenient for personnel to take out the steel pipe from the bottom of the rotating frame 10 when the rotating frame 10 does not move up, and then it is convenient for personnel to still compress other steel pipes and continue welding when taking out the processed steel pipe. Therefore, when the fixture is in use, it is convenient for personnel to fix several steel pipes with different diameters at the same time, and then it is convenient for personnel to weld steel pipes with different diameters.

[0030] Figure 2 It is shown that the conical plate 3 is overlapped on the top of the lifting rod 11, the end of the rotating rod 6 close to the processing motor 5 passes through the fixed frame 4, and the other end of the rotating rod 6 is inserted into the inside of the fixed frame 4, so that the rotating rod 6 is easy to rotate in the fixed frame 4. A pair of collars 12 are provided at both ends of the sleeve 7, and the collars 12 are fixedly sleeved on the outer end of the rotating rod 6;

[0031] Figure 4 It is shown that a limiting groove 13 is provided on the inner side wall of the rectangular groove 2, and limiting blocks 14 adapted to the limiting groove 13 are fixedly connected to symmetrical positions at the left and right ends of the conical plate 3;

[0032] When in use, the limit block 14 can improve the stability of the conical plate 3 when it moves up and down in the rectangular groove 2. During the upward movement of the limit block 14, since the length of the limit groove 13 is certain, the upward movement height of the limit block 14 is also certain, thereby preventing the conical plate 3 from separating from the rectangular groove 2.

[0033] The second implementation method:

[0034] Based on the first embodiment, this embodiment adds structures such as a base 15 and a plug rod 19, and the rest of the parts are consistent with the first embodiment.

[0035] Figure 5-7The surface of the mounting seat 1 is shown to be sleeved with a base 15, and a fixing plate 16 is fixedly connected to the left and right ends of the base 15 near the bottom. The upper end of the fixing plate 16 is fixedly connected to a support frame 17, and the upper end of the support frame 17 is fixedly connected to a semicircular block 18. A plug-in rod 19 is inserted into the interior of the semicircular block 18. One end of the plug-in rod 19 passes through the base 15 and is inserted into the interior of the mounting seat 1. The upper end of the support frame 17 is located on one side of the semicircular block 18 and is fixedly connected to a first magnetic block 20. The bottom end of the plug-in rod 19 is fixedly connected to a second magnetic block 2 1, a reinforcement groove 22 is provided on the inner side wall of the base 15, and reinforcement blocks 23 matching the reinforcement groove 22 are fixedly connected at the positions near the bottom of the left and right ends of the mounting base 1. The reinforcement blocks 23 can prevent the mounting base 1 from moving forward and backward in the base 15, and the bottom end of the second magnetic block 21 is in contact with the upper end of the first magnetic block 20. A rubber block 24 is fixedly connected to the bottom end of the fixing plate 16. After the rubber block 24 contacts the platform, it can increase the friction between the fixture and the platform, thereby improving the stability of the fixture on the platform.

[0036] This solution can be achieved by moving the mounting base 1 up and down after fixing the steel pipe on the mounting base 1. After moving the mounting base 1 to a suitable height, the plug-in rod 19 needs to be pushed so that one end of the plug-in rod 19 passes through the base 15 and is inserted into the interior of the mounting base 1, thereby fixing the mounting base 1. At the same time, the first magnetic block 20 will be adsorbed together with the second magnetic block 21, thereby improving the stability of the plug-in rod 19. Therefore, the fixture is convenient for personnel to adjust the steel pipe to a height suitable for welding.

[0037] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
