Description

Technical Field

[0001] The utility model specifically relates to an all-round welding device for nonferrous metal pipes. Background Art

[0002] Non-ferrous metal pipes refer to those metal pipes that do not contain iron or have very low iron content. They are a type of metal pipe, mainly copper pipes, brass pipes, lead pipes, aluminum pipes, and titanium pipes. They usually have good electrical and thermal conductivity and are widely used in various fields. When non-ferrous metal pipes are used to transport fluids such as water, gas or chemicals, especially when high-pressure or corrosive fluids are involved, the connection between two non-ferrous metal pipes can provide good sealing through welding, thereby preventing leakage of the transported medium.

[0003] However, when nonferrous metal pipes of different lengths are welded, the positions of the welds vary. Existing welding devices require workers to manually adjust the position of the welding gun to align it with the weld of the nonferrous metal pipe. This has a low degree of automation and takes a lot of time.

[0004] Therefore, it is necessary to invent a nonferrous metal pipe omnidirectional welding device to solve the above problems. Utility Model Content

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0032] The utility model provides Figure 1-4The illustrated all-round welding device for nonferrous metal pipes comprises a bottom plate 1, a support rod 2 arranged above the bottom plate 1 for supporting the metal pipe, a welding assembly 3 arranged on the outer ring of the support rod 2, the welding assembly 3 comprising an annular plate 31, a gear ring 32 sleeved on the annular plate 31, a welding gun 33 installed on one side of the gear ring 32, a gear 34 kneaded with the gear ring 32, and a first motor 35 installed on the annular plate 31, the output end of the first motor 35 is connected to the gear 34, and a horizontal driving assembly 4 arranged on the top of the bottom plate 1, the top of the horizontal driving assembly 4 is installed with a connecting plate 41, the top of the connecting plate 41 is connected to the bottom of the annular plate 31, and is used to drive the welding assembly 3 to move horizontally along the length direction of the support rod 2;

[0033] The support rod 2 is hollow and has a square hole 5 with the same length as the support rod 2 running through it longitudinally. A pushing assembly 6 is arranged inside the support rod 2. The pushing assembly 6 includes a screw 61, a moving block 62 which is sleeved on the outside of the screw 61 and can translate left and right along the square hole 5, grooves provided at the top and bottom of the moving block 62, a baffle 63 arranged inside the groove, and a spring 64 installed between the baffle 63 and the moving plate, which are used to push the metal tube to make the welding parts of the two sections of the metal tube fit together.

[0034] In one embodiment, a limit ring 36 is provided on both sides of the gear ring 32, and the inner wall of the limit ring 36 is connected to the outside of the annular plate 31, so as to limit the position of the gear ring 32 and prevent the gear ring 32 from translating left and right along the outside of the annular plate 31;

[0035] The top of the bottom plate 1 is provided with sliding grooves transversely on both the front and rear sides, and a slider 37 is arranged inside the sliding groove. A slant plate 38 is installed on the top of the slider 37. The top of the slant plate 38 is connected to the outer circle of the annular plate 31. When the annular plate 31 moves left and right under the drive of the horizontal driving component 4, the slant plate 38 and the slider 37 can be synchronously translated left and right, thereby supporting the front and rear sides of the annular plate 31, so that the annular plate 31 has higher stability when moving.

[0036] In one embodiment, the two baffles 63 are connected to limit plates 65 on both sides, and the left and right side walls of the moving block 62 in the groove are provided with makeshift grooves for the limit plates 65 to slide up and down, so that the baffle 63 will not slide out to the outside of the support rod 2 under the elastic force of the spring 64, and can ensure that the bottom of the inclined section 69 is located in the groove. A vertical plate 66 is provided on one side of the top of the base plate 1, and a second motor 67 is installed on the inner side of the vertical plate 66. The output end of the second motor 67 is connected to the screw rod 61 for driving the screw rod 61 to rotate, so that the moving block 62 can translate along the square hole 5, and the end of the support rod 2 is connected to the side wall of the vertical plate 66 for installing the support rod 2.

[0037] In one embodiment, a circular plate 68 is installed at one end of the screw rod 61 away from the vertical plate 66 to prevent the moving block 62 from sliding out of the support rod 2, thereby limiting the moving block 62, and the staff can also modify the circular plate 68 into a strip plate, and set it to be rotatably connected with the screw rod 61, and connected to the front and rear inner walls of the support rod 2, so as to support the end of the screw rod 61 and ensure the stability of the screw rod 61 during rotation. The top of the two baffles 63 away from the vertical plate 66 is provided with an inclined section 69, and under the elastic force of the spring 64, the top of the inclined section 69 of the two baffles 63 is located on the outside of the support rod 2, and the bottom of the inclined section 69 is located in the groove, so that the non-ferrous metal tube can resist the inclined section 69 of the baffle 63 when being plugged in, and force the baffle 63 to move downward under pressure, thereby making way for the non-ferrous metal tube so that it can be plugged into the outside of the support rod 2.

[0038] The specific implementation method is as follows: when the utility model is used, Figure 1 , 4 As shown, two nonferrous metal tubes 7 of different lengths are inserted on the outside of the support rod 2, waiting for welding. Specifically:

[0039] The staff inserts the first non-ferrous metal tube 7 which matches the outer diameter of the support rod 2 along the end of the support rod 2 to the outside of the support rod 2, and gradually pushes it toward the vertical plate 66. As the non-ferrous metal tube 7 moves, the two baffles 63 exposed outside the support rod 2 will approach each other due to the pressure of the non-ferrous metal tube 7. When the end of the non-ferrous metal tube 7 leaves the top of the baffle 63, the two baffles 63 will move away from each other under the elastic force of the spring 64, and then pop out again, so that the inclined surface section 69 is exposed outside the support rod 2. When the end of the non-ferrous metal tube 7 contacts the side of the vertical plate 66, the staff inserts the second non-ferrous metal tube 7 to the outside of the support rod 2 in the same way as above.

[0040] Then, the staff starts the second motor 67, and the output end of the second motor 67 rotates to drive the screw 61 to rotate, so that the moving block 62 moves along the square hole 5 toward the vertical plate 66. As the moving block 62 continues to translate, the moving block 62 will eventually contact the outer end of the second non-ferrous metal tube 7 and push the second non-ferrous metal tube 7 closer to the vertical plate 66, so that the adjacent ends of the two non-ferrous metal tubes 7 are in contact, and the contact surface is the welding point.

[0041] At this time, the staff starts the horizontal drive assembly 4, so that the connecting plate 41 also moves toward the vertical plate 66, thereby driving the annular plate 31 to move, and further, the welding gun 33 moves toward the vertical plate 66. When the welding end of the welding gun 33 moves to the welding point of the two non-ferrous metal pipes 7, the horizontal drive assembly 4 stops moving, so that the welding end of the welding gun 33 is aligned with the welding point.

[0042] Then the welding gun 33 starts to work and welds the welded joint. At this time, the output end of the first motor 35 is started, driving the gear 34 to rotate, and then driving the gear ring 32 to rotate, so that the welding gun 33 can make a circular motion with the axis of the annular plate 31 as the center, and perform all-round welding on the annular welded joint. When the welding gun 33 rotates one circle, the welding process of the two non-ferrous metal pipes 7 can be completed. Then the first motor 35 drives the welding gun 33 to reset, and the horizontal drive assembly 4 drives the annular plate 31 to reset. The staff simply presses the two baffles 63 to make the two baffles 63 slide into the groove again and contact the limit of the end of the non-ferrous metal pipe 7, so that the non-ferrous metal pipe 7 that has been welded into one and is plugged into the outer side of the support rod 2 can be pulled out.

[0043] Among them, the horizontal drive component 4 is a horizontal drive realized by screw drive, belt drive, or cylinder drive, and no further description is given here, that is, the horizontal drive component 4 is not specifically described. For those skilled in the art, it is fully possible to understand the specific implementation scheme of the horizontal drive component 4 to realize the horizontal movement of the connecting plate 41. Therefore, in order to avoid redundant description, the specific detailed description of the horizontal drive component 4 is omitted, and it is only mentioned in a functionally limited manner;

[0044] This embodiment specifically solves the problem in the prior art that when non-ferrous metal pipes 7 of different lengths are welded, the positions of the welds are various, and the existing welding device requires workers to manually adjust the position of the welding gun 33 to align it with the weld of the non-ferrous metal pipe 7, which has a low degree of automation and takes a lot of time.

[0045] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
