[0027] The following is combined with Figure 1-2 This application is described in further detail.
[0028] The embodiment of the present application discloses an adjustable small-diameter pipe interface fixture for welding. Figure 1 and Figure 2 The adjustable small-diameter pipe interface fixture for welding includes a fixing part 1, a pushing part 2 slidably connected to the fixing part 1, and a connecting rod 3 for connecting the fixing part 1 and the pushing part 2. The pushing part 2 can slide close to or away from the fixing part 1 to clamp the pipe to be welded, thereby realizing the docking of the pipe structure.
[0029] The fixing part 1 and the pushing part 2 are both made of angle steel. The openings of the fixing part 1 and the pushing part 2 are arranged opposite to each other, and a clamping space is formed between the fixing part 1 and the pushing part 2. The two pipe ends to be welded are placed in the clamping space, and the fixing part 1 and the pushing part 2 clamp the two pipes, thereby facilitating welding of the two pipes.
[0030] A rubber pad 7 is attached to the surface of the fixing member 1 facing the pusher 2. This prevents pipe deformation during the process of clamping the pipe between the fixing member 1 and the pusher 2. Furthermore, the edge of the rubber pad 7 lies within the edge of the fixing member 1 or the pusher 2, meaning that its width does not exceed that of the fixing member 1 or the pusher 2. This prevents damage to the rubber pad 7 during pipe welding.
[0031] The connecting rod 3 is a U-shaped rod with its opening facing the fixing member 1 and the thrust member 2. One end of the connecting rod 3 is welded to the outside of the fixing member 1, and the other end is welded to a sleeve 4, with the axis of the sleeve 4 facing the fixing member 1. The inner wall of the sleeve 4 is provided with an internal thread. An insertion rod 21 is welded to the outside of the thrust member 2 and is located at a corner of the thrust member 2. The insertion rod 21 is inserted into the end of the sleeve 4 facing the fixing member 1, forming a sliding connection between the thrust member 2 and the sleeve 4.
[0032] A screw rod 5 is screwed into the end of the sleeve 4 away from the fixing part 1, and one end of the screw rod 5 is in conflict with the insertion rod 21, and the other end extends out of the sleeve 4. A handle 6 is welded to the end of the screw 5 away from the fixing part 1. The handle 6 and the screw 5 are arranged perpendicular to each other to form a "T" structure. By rotating the screw 5 to push the insertion rod 21, the pushing part 2 can slide toward the fixing part 1.
[0033] The implementation principle of an adjustable small-diameter pipe interface fixture for welding in an embodiment of the present application is as follows: two pipes to be connected are placed in the clamping space, so that the outer walls of the two pipes are in contact with the inner wall of the fixing part 1, and the ports of the two pipes are in contact with each other, and then the handle 6 is turned, and the screw 5 pushes the insertion rod 21 and the pushing part 2, so that the pushing part 2 moves toward the fixing part 1, and finally the inner wall of the pushing part 2 is also in contact with the outer wall of the pipe, so that the fixing part 1 and the pushing part 2 clamp the pipe, and align the interfaces of the two pipes. Compared with the traditional manual docking method, the use of the pipe interface fixture in the present application can improve the accuracy of pipe docking, thereby improving welding quality, avoiding deviations, and increasing rework and material consumption.
[0034] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
