[0002] Flange, also known as flange, usually refers to a disc-shaped metal body with several fixing holes around it for connecting other things. This thing is widely used in machinery, so its appearance is also strange. As long as it looks like this, it is collectively called a flange.

[0003] In some cases where flanges are used, workers will use a welding gun to weld the flange to the metal pipe, so as to connect the two pipes together through the flange to complete the task of transporting liquids. However, since the outer wall of the pipe and the surface of the flange are relatively smooth, the metal pipe will slide or shake during welding, which will affect the axial accuracy after welding and the sealing of the connection. Utility Model Content

[0004] In order to overcome the above defects, the utility model provides a flange with an auxiliary welding structure, which solves the problem that the metal pipe may slide or shake during welding due to the smooth outer wall of the pipe and the surface of the flange, thereby affecting the connection sealing.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flange with an auxiliary welding structure, comprising a workbench, a fixed platform is installed on the workbench, a hollow plate is connected to one side of the workbench, a support frame is connected below the workbench, a fixed frame is connected to the support frame, a hydraulic push rod is installed on the fixed frame, a push block is connected to the movable end of the hydraulic push rod, a flange body is installed on the fixed platform, a pipeline is installed on the flange body, a first slide groove is opened on the fixed platform, and a guide rod is connected in the first slide groove;

[0006] A slider is slidably connected in the first slide groove, a connecting plate is connected below the slider, a tensioning plate is connected above the slider, a second slide groove is provided on the hollow plate, a sliding plate is slidably connected in the second slide groove, a clamping plate is connected to the sliding plate, a groove is provided inside the flange body, a second spring is connected inside the groove, and an auxiliary block is connected to one end of the second spring.

[0007] As a further solution of the utility model: the push block is designed in a truncated cone shape, and one side of the connecting plate is designed in an inclined surface and fits with the outer wall of the push block.

[0008] As a further solution of the utility model: an anti-skid pad is connected to the lower side of the support frame, a buffer pad is connected to one side of the tensioning plate, and anti-skid patterns are arranged on the anti-skid pad and the buffer pad.

[0009] As a further solution of the utility model: a sliding hole is opened on the slider, and the slider slides on the guide rod through the sliding hole. A return spring is connected to one side of the slider, and one end of the return spring is connected to the wall of the first sliding groove.

[0010] As a further solution of the utility model: a first spring is connected to one side of the sliding plate, one end of the first spring is connected to the inner wall of the hollow plate, and one side of the clamping plate is designed to be arc-shaped.

[0011] As a further solution of the utility model: an engaging groove is provided on the inner wall of the flange body, an arc groove is provided on one side of the auxiliary block and is engaged with the engaging groove, and the auxiliary block is designed as an L-shape as a whole and one end slides in the groove.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The flange with an auxiliary welding structure is provided with a hydraulic push rod, a push block, a first slide groove, a slider, a connecting plate, a tensioning plate, a sliding plate, a first spring and a clamping plate. By placing the flange body inserted into the pipeline on a fixed platform, the hydraulic push rod is started to push the push block, so that the push block can push the connecting plate through the inclined surface of the connecting plate, so that the slider slides along the first slide groove, so that the tensioning plate can contact the inner wall of the pipeline, thereby tightening and fixing the pipeline to prevent the pipeline from sliding during welding. After the upper part of the flange body is welded to the pipeline, the flange body is picked up and rotated at the same time, and the pipeline is placed between the two clamping plates, so that the sliding plate slides along the second slide groove and compresses the first spring, so that the clamping plate is pushed to clamp and fix the pipeline through the rebound of the first spring to prevent the pipeline from sliding, and the bottom of the flange body is welded to the pipeline.

[0014] 2. The flange with an auxiliary welding structure is provided with a groove, a second spring, an auxiliary block and an engaging groove. The worker manually pushes the auxiliary block to move and inserts the pipe into the inner circle of the flange body. When the auxiliary block moves, one end of the auxiliary block will slide in the groove and compress the second spring. At the same time, the auxiliary block will also be embedded in the engaging groove and fit with the inner circle of the flange body. The rebound force generated by the compression of the second spring will push the auxiliary block to fit and contact the outer wall of the pipe, thereby clamping the pipe to facilitate welding by the workers. During welding, the auxiliary block will be welded to the pipe together, thereby increasing the welding points and improving the stability of the welding. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a flange with an auxiliary welding structure, including a workbench 1, a fixed platform 2 is installed on the workbench 1, a hollow plate 3 is connected to one side of the workbench 1, a support frame 4 is connected to the lower part of the workbench 1, a fixed frame 5 is connected to the support frame 4, a hydraulic push rod 6 is installed on the fixed frame 5, a push block 7 is connected to the movable end of the hydraulic push rod 6, a flange body 8 is installed on the fixed platform 2, a pipe 9 is installed on the flange body 8, a first slide groove 11 is opened on the fixed platform 2, a guide rod 12 is connected in the first slide groove 11, a slider 13 is slidably connected in the first slide groove 11, and the slider 13 A sliding hole 17 is provided on the top, and the slider 13 slides on the guide rod 12 through the sliding hole 17. A return spring 18 is connected to one side of the slider 13, and one end of the return spring 18 is connected to the groove wall of the first slide groove 11. A connecting plate 14 is connected to the bottom of the slider 13. The push block 7 is designed in a truncated cone shape, and one side of the connecting plate 14 is designed with an inclined surface and fits with the outer wall of the push block 7. The truncated cone push block 7 can push the connecting plate 14 to move by fitting with the inclined surface of the connecting plate 14, and the movement of the slider 13 is guided and restricted by the guide rod 12 to prevent the slider 13 from disengaging from the first slide groove 11 when moving, so that the tensioning plate 15 can move smoothly.

[0022] A tensioning plate 15 is connected above the slider 13, an anti-skid pad 10 is connected below the support frame 4, and a buffer pad 16 is connected to one side of the tensioning plate 15. Both the anti-skid pad 10 and the buffer pad 16 are provided with anti-skid patterns. The anti-skid pad 10 increases the friction between the support frame 4 and the ground, thereby preventing the support frame 4 from sliding during operation, and the buffer pad 16 can buffer the contact between the tensioning plate 15 and the inner wall of the pipe 9 and prevent the pipe 9 from sliding.

[0023] A second slide groove 19 is provided on the hollow plate 3, and a sliding plate 20 is slidably connected in the second slide groove 19, and a clamping plate 21 is connected to the sliding plate 20, and a first spring 22 is connected to one side of the sliding plate 20, and one end of the first spring 22 is connected to the inner wall of the hollow plate 3, and one side of the clamping plate 21 is designed to be arc-shaped. The arc-shaped design on one side of the clamping plate 21 enables the clamping plate 21 to fit with the outer wall of the pipe 9, and the sliding of the sliding plate 20 in the second slide groove 19 can prevent the clamping plate 21 from being skewed during movement.

[0024] A groove 24 is provided inside the flange body 8, and a second spring 25 is connected inside the groove 24. An auxiliary block 26 is connected to one end of the second spring 25. An engaging groove 23 is provided on the inner wall of the flange body 8. An arc groove is provided on one side of the auxiliary block 26 and is engaged with the engaging groove 23. The auxiliary block 26 is L-shaped as a whole and one end slides in the groove 24. The arc groove on one side of the auxiliary block 26 can fit in contact with the outer wall of the pipe 9, so that the auxiliary block 26 is pushed to clamp the pipe 9 through the rebound of the second spring 25 to prevent accidental movement of the flange body 8 during welding.

[0025] The working principle of the utility model is:

[0026] When the worker pushes the auxiliary block 26 into the fitting groove 23, the pipe 9 is gradually inserted into the inner circle of the flange body 8. The auxiliary block 26 embedded in the fitting groove 23 will fit with the inner circle of the flange body 8 and compress the second spring 25, so that the auxiliary block 26 is pushed to clamp the outer wall of the pipe 9 by the rebound force generated by compressing the second spring 25. Then, the flange body 8 inserted into the pipe 9 is placed on the fixed platform 2, and the hydraulic push rod 6 is started to push the push block 7, so that the push block 7 pushes the connecting plate 14 to move, so that the slider 13 slides along the guide rod 12 through the slide hole 17. The first spring 22 is compressed, and the clamping plate 21 is pushed to clamp and fix the pipe 9 by the rebound of the first spring 22, so as to complete the work of welding the bottom of the flange body 8 to the pipe 9.
