Detailed implementation manners

[0021] The present utility model will be further described in detail below in conjunction with the drawings and embodiments. The same components are denoted by the same reference numerals.

[0022] As Figures 1-3 shown, a flange welding platform includes an installation platform 3. At least two positioning rods 4 are provided on the installation platform 3. Traction units 5 are respectively provided on the installation platform 3 corresponding to the positioning rods 4. The traction units 5 are connected to the positioning rods 4 and are used to drive the positioning rods 4 to move. A limiting surface 6 is formed on the outer wall of the positioning rod 4. The limiting surface 6 is used to respectively abut against the inner walls of the pipe body 2 and the disk body 1 after moving, so that the axes of the pipe body 2 and the disk body 1 are aligned.

[0023] Preferably, a blower unit is further included. An air outlet cavity 7 is formed in the positioning rod 4. Air outlets 8 are arranged on the limiting surface 6 in a row. The blower unit is connected to the air outlet cavity 7 and is used to supply air into the air outlet cavity 7.

[0024] Specifically, the blower unit is composed of a blower and pipelines. This part is prior art and will not be elaborated here.

[0025] During use, the positioning rod 4 is pulled by the traction unit 5, so that the positioning rod 4 can respectively abut against the inner walls of the pipe body 2 and the disk body 1, thereby realizing the positioning and limitation of the pipe body 2 and the disk body 1, ensuring that the axes of the pipe body 2 and the disk body 1 are aligned, and further ensuring the welding precision of the two. Further, the blower unit is used to supply air into the air outlet cavity 7, and the air is discharged through the air outlets 8. Since the disk body 1, the pipe body 2 and the installation platform 3 will jointly form a unidirectionally open heat dissipation space, the heat dissipation effect of the air discharged by the blower can be greatly improved, so as to accelerate the cooling of the disk body 1 and the pipe body 2, thereby facilitating the disassembly of the disk body 1 and the pipe body 2 by personnel after welding is completed, and improving production efficiency.

[0026] Preferably, a limiting groove 9 is provided on the installation platform 3 corresponding to the positioning rod 4. The traction unit 5 includes a spring 10 and a driving block 11. The driving block 11 is slidably arranged in the limiting groove 9. Two ends of the spring 10 are respectively connected to the driving block 11 and the limiting groove 9. The lower end of the positioning rod 4 is connected to the driving block 11.

[0027] During use, the elastic force of the spring 10 is used to pull the driving block 11, so as to realize the abutting and limiting of the positioning rod 4 against the inner wall of the disc body 1 / tube body 2, making its adjustment more convenient and rapid, so as to facilitate its separation after welding is completed.

[0028] Preferably, a limiting rod 12 is arranged in the limiting groove 9, and the driving block 11 is provided with a limiting hole 13 corresponding to the limiting rod 12 and is slidably connected with the limiting rod 12 through the limiting hole 13.

[0029] The sliding of the limiting rod 12 and the limiting hole 13 can limit the driving block 11, so as to prevent the driving block 11 from detaching from the limiting groove 9 during the movement, making the movement of the driving block 11 more stable.

[0030] Preferably, the positioning rod 4 includes an outer sleeve 14 and a hollow inner tube 15. An air supply channel 16 is arranged in the driving block 11 and a connection port 17 is formed corresponding to the upper end of the driving block 11. The lower end of the hollow inner tube 15 is threadedly connected with the connection port 17. An installation hole 18 is formed on the outer sleeve 14. One end of the hollow inner tube 15 is rotatably connected with the outer sleeve 14 through the installation hole 18. The limiting surface 6 is the plane where the surface of the outer sleeve 14 is located, the air outlet cavity 7 is the gap between the outer sleeve 14 and the hollow inner tube 15, and the air supply channel 16 is communicated with the air outlet cavity 7 through the hollow inner tube 15.

[0031] During use, the lower end of the hollow inner tube 15 is threadedly connected with the connection hole. The threaded connection method can ensure the connection stability between the hollow inner tube 15 and the driving block 11. Further, the air supply channel 16 is connected to the blower unit to supply air to the air supply channel 16. In this embodiment, holes are formed on the hollow inner tube 15, and the air supply channel 16 is connected to the air outlet cavity 7 through the holes.

[0032] In a welding method, since the spring 10 is used for driving in this embodiment, the positioning rod 4 applies a relatively small force to the inner wall of the tube body 2 / disc body 1. Therefore, in combination with the rotational connection mode of the hollow inner tube 15 and the outer sleeve 14, the disc body 1 / tube body 2 can be rotated simultaneously during the welding process to achieve single-point welding.

[0033] Preferably, arc-shaped clamping jaws 19 are symmetrically arranged on the installation platform 3, and a driving mechanism 20 is arranged on the installation platform 3 corresponding to the arc-shaped clamping jaws 19. The driving mechanism 20 is used to drive the two arc-shaped clamping jaws 19 to approach / separate from each other.

[0034] The arrangement of the arc-shaped clamping jaws 19 can clamp the disc body 1 to ensure stability during welding, thus facilitating the torch to perform circumferential welding.

[0035] Preferably, the center point formed by the two arc-shaped clamping jaws 19 coincides with the center point formed by at least two positioning rods 4, so as to ensure the stable force applied by the plurality of positioning rods 4 to the inner wall of the disc body 1 / tube body 2 during the welding process, thereby improving the welding accuracy.

[0036] Preferably, the installation platform 3 is provided with a driving groove 21 corresponding to the arc-shaped clamping jaws 19. The driving mechanism 20 is a bidirectional screw rod rotatably arranged in the driving groove 21. The lower end of the arc-shaped clamping jaw 19 forms a connecting portion and is limitedly slidable in the driving groove 21. The bidirectional screw rod passes through the two connecting portions respectively and is threadedly connected with the two connecting portions.

[0037] The setting of the bidirectional screw rod can realize the driving of the two arc-shaped clamping jaws 19, and at the same time make the overall structure more concise.

[0038] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches should also be regarded as the protection scope of the present invention.
