Description

Technical Field

[0001] The present invention relates to the technical field of drainage pipe fitting welding, and more specifically, to a butt welding device for water supply and drainage pipe fittings. Background Art

[0002] Steel pipe welding butt joint refers to the process of aligning and welding the ends of two steel pipes during the welding process. This process requires a high degree of precision and skill to ensure the quality of the weld seam and the integrity of the pipeline system. Therefore, the forming quality of the butt welding affects the quality of the steel pipe.

[0003] In the prior art, an automatic butt welding device for water supply and drainage pipe fittings with the publication number of CN118635799A, which relates to the technical field of welding, includes: a placement unit, including placement racks arranged at the bottoms of the left and right sides of the processing pipe, and the placement racks are movably clamped with the processing pipe through anti-slip cylinders; a fixing and driving unit, which is arranged on the top of the placement unit; a uniform welding unit, which is arranged at the top end of the placement unit. When welding a steel pipe, place a section of the processing pipe on the placement rack at the top of the feeding table and then push the processing pipe through the through-ring rack to the surface of the placement rack at the top of the power table. Then, place another section of the processing pipe on the placement rack at the top of the feeding table and place the interfaces of the two sections of the processing pipe on the surfaces of the fixed sleeve and the movable arc plate. Thus, when the interfaces of the two sections of the processing pipe are butted, they are supported by the fixed sleeve and the movable arc plate, so that the weld seam interface is butted more precisely.

[0004] However, when the existing drainage pipe fitting butt welding device is in use, although it can better improve the welding quality of the drainage pipe fittings to be butted, when using the welding device, it is necessary for personnel to carry the drainage pipe fittings to the welding device one by one. For multiple drainage pipe fittings, the automatic feeding, pushing, and butt welding efficiency on the welding device is not high, which increases the tediousness of the staff's frequent feeding of the drainage pipe fittings and reduces the welding processing efficiency of the butt welding device for the drainage pipe fittings, not meeting people's usage requirements. Therefore, we propose a butt welding device for water supply and drainage pipe fittings. Summary of the Invention

Detailed implementation manners

[0039] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in conjunction with the drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects of the present invention as follows.

[0040] Embodiment 1:

[0041] Please refer to Figures 1 to 11 , this embodiment provides a water supply and drainage pipe fitting butt welding device, including a device main body 1. The device main body 1 includes a ring-passing frame 2 and a placing table 3. A ring-passing frame 2 is fixedly connected to the outer wall of the device main body 1, a placing table 3 is fixedly connected to the outer wall of the device main body 1, and a conveying frame 5 located on one side of the ring-passing frame 2 is fixedly connected to the outer wall of the device main body 1.

[0042] Example 2:

[0043] Based on Example 1, the gap feeding mechanism 4 is further disclosed.

[0044] As Figures 5 - 8 shown, the device main body 1 further includes:

[0045] The gap feeding mechanism 4 is arranged on the outer wall of the placement table 3 and is used for the elastic clip-type automatic feeding of the drainage pipe fittings to be processed;

[0046] The variable pitch mechanism 9 is arranged on one side of the gap feeding mechanism 4 and is used for adjusting the automatic feeding movement of drainage pipe fittings with different lengths;

[0047] The gap feeding mechanism 4 includes a pushing rod 403 and a ejecting rod 408. A sliding plate 401 is slidably connected to the outer wall of the placement table 3. An electric push rod 402 is fixedly connected to the outer wall of the sliding plate 401. One end of the electric push rod 402 is fixedly connected to a pushing rod 403 that is slidably connected to the outer wall of the placement table 3. A pipe fitting main body 404 is placed on the surface of the placement table 3. A first limiting frame 406 is slidably connected to the outer wall of the placement table 3. A second limiting frame 407 that is slidably connected to the outer wall of the first limiting frame 406 is slidably connected to the outer wall of the placement table 3. An ejecting rod 408 located on one side of the pipe fitting main body 404 is slidably connected to the outer wall of the first limiting frame 406. A spring 409 that is fixedly connected to the side wall of the first limiting frame 406 is fixedly connected to the outer wall of the ejecting rod 408. A material placing frame 410 is fixedly connected to the top of the first limiting frame 406.

[0048] As Figure 5 shown, a pushing groove 405 is opened at the connection part between the outer wall of the placement table 3 and the pushing rod 403, and the pushing groove 405 is arranged on the movement track of the pushing rod 403 in the pushing state. The length of the pushing rod 403 is greater than the distance between the first limiting frame 406 and the second limiting frame 407. The outer wall contour of the connection part between the first limiting frame 406 and the second limiting frame 407 is U-shaped. The pipe fitting main bodies 404 between the first limiting frame 406 and the second limiting frame 407 are arranged horizontally in a line, which is beneficial to improving the pushing stability of the pushing rod 403 on the drainage pipe fittings through the setting of the pushing groove 405, and is beneficial to making the next root drainage pipe fitting keep the extrusion and ejection state by the length of the pushing rod 403 being greater than the distance between the first limiting frame 406 and the second limiting frame 407.

[0049] As Figure 6As shown, the pipe fittings main bodies 404 inside the blanking frame 410 are arranged vertically in a line. The ejector rod 408 is arranged at the rear side when the pipe fittings main bodies 404 inside the blanking frame 410 are being unloaded. The ejector rod 408 is respectively arranged in one-to-one correspondence with the first limiting frame 406 and the second limiting frame 407. The conveying frame 5 is arranged on the movement track of the pushing rod 403. There are two groups of placing tables 3, and the position distributions of the two groups of placing tables 3 are symmetrical about the central axis of the ring-piercing frame 2, which is conducive to the vertical linear arrangement of the pipe fittings main bodies 404 inside the blanking frame 410 to automatically replenish the drainage pipe fittings between the limiting frames.

[0050] As Figure 5 and Figure 10 shown, a first servo motor 6 is fixedly connected to the outer wall of the placing table 3. The output end of the first servo motor 6 is fixedly connected to a first threaded rod 7 that is threadedly connected to the outer wall of the sliding plate 401. A limiting rod 8 that is slidably connected to the outer wall of the sliding plate 401 is fixedly connected to the outer wall of the placing table 3. Through the arrangement of the sliding plate 401 sliding along the outer wall of the limiting rod 8, the drained pipe fittings after butt welding are pushed and unloaded from the pushing groove 405.

[0051] As Figure 10 shown, the sliding plate 401 forms a sliding structure between the first threaded rod 7 and the limiting rod 8, which is conducive to the rotation of the first threaded rod 7 to drive the sliding plate 401 to slide along the outer wall of the limiting rod 8, enabling the convenient storage of the pushing rod 403 and making the drained pipe fittings after butt welding be pushed and unloaded from the pushing groove 405.

[0052] As Figure 11 shown, the variable pitch mechanism 9 includes a rotating rod 905. A second servo motor 901 is fixedly connected to the outer wall of the placing table 3. The output end of the second servo motor 901 is fixedly connected to a second threaded rod 902 that is rotatably connected to the outer wall of the placing table 3. A threaded slide rod 903 that is slidably connected to the outer wall of the placing table 3 is threadedly connected to the outer wall of the second threaded rod 902. A fixing groove 904 is formed at the connecting part between the outer wall of the placing table 3 and the threaded slide rod 903. The outer wall of the threaded slide rod 903 is rotatably connected to a rotating rod 905 that is rotatably connected to the outer wall of the first limiting frame 406. By setting the rotating rod 905, when automatically loading the pipe fittings in a spring clip manner through the pushing rod 403, in order to improve the flexible pushing efficiency of the drainage pipe fittings with different lengths, the second servo motor 901 can be turned on. Through the rotation of the second threaded rod 902, the threaded slide rod 903 is driven to slide along the inner wall of the fixing groove 904. The sliding of the threaded slide rod 903 drives the rotation of the two groups of rotating rods 905, driving the first limiting frame 406 and the second limiting frame 407 to slide relatively, so as to adjust the placing distance between the limiting frames and meet the need for automatically replenishing the drainage pipe fittings with different lengths.

[0053] As Figure 11As shown, the threaded sliding rod 903 and the fixed groove 904 form a lifting structure through the second threaded rod 902. The rotating rod 905 and the first limiting frame 406 form a rotating structure through the threaded sliding rod 903. And there are two groups of rotating rods 905, and the position distributions of the two groups of rotating rods 905 are symmetrically arranged with respect to the central axis of the threaded sliding rod 903, which is beneficial to the rotation of the second threaded rod 902, driving the threaded sliding rod 903 to slide along the inner wall of the fixed groove 904, playing a role in driving the rotating rod 905 to rotate conveniently, so as to adjust the placement distance between the limiting frames and meet the need for automatic feeding of drainage pipe fittings of different lengths.

[0054] As Figure 1 , Figure 8 and Figure 9 shown,

[0055] The pushing mechanism 10 is arranged on the outer wall of the device main body 1;

[0056] The pushing mechanism 10 includes a pushing rod 1007 and an observation scale 1009. A control box 1001 is fixedly connected to the outer wall of the device main body 1. A third servo motor 1002 is fixedly connected to the outer wall of the control box 1001. The output end of the third servo motor 1002 is fixedly connected to a bevel gear set 1003 rotatably connected to the inner wall of the control box 1001. The outer wall of the bevel gear set 1003 is fixedly connected to a third threaded rod 1004 rotatably connected to the outer wall of the device main body 1. The outer wall of the third threaded rod 1004 is threadedly connected to a reciprocating rod 1005 slidably connected to the outer wall of the device main body 1. A chute 1006 is opened at the connecting part of the outer wall of the device main body 1 and the reciprocating rod 1005. A pushing rod 1007 slidably connected to the outer wall of the conveying frame 5 is fixedly connected to the outer wall of the reciprocating rod 1005. An indicator plate 1008 is fixedly connected to the outer wall of the pushing rod 1007. An observation scale 1009 located on one side of the indicator plate 1008 is fixedly connected to the outer wall of the conveying frame 5. By setting the indicator plate 1008, it is beneficial that when the drainage pipe fitting is pushed into the conveying frame 5, the third servo motor 1002 can be turned on to drive the third threaded rod 1004 to rotate through the rotation of the bevel gear set 1003. The rotation of the third threaded rod 1004 drives the reciprocating rod 1005 to slide along the inner wall of the chute 1006. The movement of the reciprocating rod 1005 drives the pushing rod 1007 to slide in the conveying frame 5. Under the indication of the indicator plate 1008 to the observation scale 1009, the staff can timely observe the pushing distances of the pipe fittings on both sides, playing a role in improving the accuracy of the butt joint position between the pipe fittings and achieving the effect of improving the butt joint welding quality of the drainage pipe fittings.

[0057] As Figure 9As shown in the figure, a reciprocating sliding structure is formed between the reciprocating rod 1005, the bevel gear set 1003 and the third threaded rod 1004 and the chute 1006. There are two sets of the third threaded rods 1004, and the rotation directions of the two sets of the third threaded rods 1004 are opposite, which is beneficial to the rotation of the bevel gear set 1003. By rotating the third threaded rod 1004, the reciprocating rod 1005 is driven to slide along the inner wall of the chute 1006, so as to automatically push and dock the drainage pipe fittings in the conveying frame 5.

[0058] As Figure 8 shown in the figure, a sliding structure is formed between the push rod 1007, the reciprocating rod 1005 and the chute 1006 and the conveying frame 5. There are two sets of observation scales 1009, and the position distributions of the two sets of observation scales 1009 are symmetrical about the central axis of the conveying frame 5. Moreover, the overall material of the conveying frame 5 is a transparent material, and the indicating direction of the indicator plate 1008 is upward, which is beneficial to the reciprocating rod 1005 sliding along the inner wall of the chute 1006, driving the push rod 1007 to slide along the inner wall of the conveying frame 5, so that the staff can timely observe the pushing distances of the pipe fittings on both sides, playing a role in improving the accuracy of the docking position between the pipe fittings and achieving the effect of improving the docking and welding quality of the drainage pipe fittings.

[0059] Working principle:

[0060] As Figures 1 - 11 shown in the figure, when the docking and welding device is used for welding the drainage pipe fittings, first, when the docking and welding device is used to dock and weld the drainage pipe fittings, in order to improve the effect of automatically loading the drainage pipe fittings on the device and reduce the workload of the staff for handling the pipe fittings, multiple pipe fittings can be laid flat between the first limiting frame 406 and the second limiting frame 407, and the electric push rod 402 is opened to drive the pushing rod 403 to slide along the inner wall of the pushing groove 405, so that the pipe fittings are pushed into the conveying frame 5. At the same time, the side wall of the pushing rod 403 will block the opening between the limiting frames and squeeze the spring 409 and the ejecting rod 408 until the pushing rod 403 disengages from the opening between the limiting frames. Under the reaction force of the spring 409 and the ejecting rod 408 being squeezed, the next pipe fitting is elastically pushed into the pushing groove 405 to meet the need for automatically replenishing the next pipe fitting and improve the efficiency of the welding device for automatically loading and processing the pipe fittings;

[0061] Next, when automatically loading the pipe fittings with the ejector rod 403, in order to improve the efficiency of flexibly pushing drainage pipe fittings of different lengths, the second servo motor 901 can be turned on. Through the rotation of the second threaded rod 902, the threaded slide rod 903 is driven to slide along the inner wall of the fixed groove 904. The sliding of the threaded slide rod 903 drives the first limiting frame 406 and the second limiting frame 407 to slide relatively through the rotation of two groups of rotating rods 905, so as to adjust the placement distance between the limiting frames and meet the need for automatic feeding of drainage pipe fittings of different lengths.

[0062] Finally, when the drainage pipe fittings are pushed into the conveying frame 5, the third servo motor 1002 can be turned on. Through the rotation of the bevel gear set 1003, the third threaded rod 1004 is driven to rotate. The rotation of the third threaded rod 1004 drives the reciprocating rod 1005 to slide along the inner wall of the chute 1006. The movement of the reciprocating rod 1005 drives the pushing rod 1007 to slide in the conveying frame 5. Under the indication of the observation scale 1009 by the indicator board 1008, the staff can timely observe the pushing distances of the pipe fittings on both sides, which plays a role in improving the accuracy of the docking position between the pipe fittings and achieving the effect of improving the docking and welding quality of the drainage pipe fittings.

Although the present invention has been disclosed as above with the preferred embodiment, it is not intended to limit the present invention.
