Description

Technical Field

[0001] This invention relates to the field of welding technology, and in particular to a welding device for preventing offset during metal product processing. Background Technology

[0002] In modern industrial production and manufacturing, the processing and joining of metal products relies heavily on welding technology. As the manufacturing industry develops towards high precision and automation, welding quality directly affects the structural strength, service life, and safety of metal products. In particular, in fields such as aerospace, automobile manufacturing, and precision instruments, the requirements for welding accuracy and stability are increasing. However, in the actual welding process, workpieces often shift due to poor positioning, thermal deformation, or external disturbances, resulting in weld position deviations that seriously affect welding quality and product consistency.

[0003] Currently, most common welding equipment relies on manual positioning or simple clamps for fixation. It is difficult to monitor and correct the slight displacement of the workpiece in real time during the welding process. Especially for pipe-type metal products of different specifications, the adaptability of welding external tricks is limited. When welding steps, it relies too much on experience, and the welding accuracy is unstable, making it difficult to meet the needs of high-quality metal product processing. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of limited adaptability of welding irregular pipes in the prior art, and to propose a metal product processing anti-deviation welding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a metal product processing anti-deviation welding device, comprising a base, side frames fixedly connected to both sides of the top of the base, a conveying mechanism and a stabilizing mechanism installed on the side frames, a first drive housing installed above the base via an electric push rod, a first transport roller rotatably connected inside the first drive housing, the surface of the first transport roller being covered with a rubber pad, a mounting frame slidably connected to the center of one end of the base, a rotating frame rotatably connected to the mounting frame, a processing mechanism installed at the end of the rotating frame, a snap-fit ​​mechanism installed on the side wall of the rotating frame, and a collection box installed at the center of the upper side of the base.

[0006] In the aforementioned anti-deviation welding equipment for metal product processing, the conveying mechanism includes a second drive housing and a second transport roller. The second transport roller is rotatably connected to the second drive housing. The second drive housing is connected to a side plate via an electric push rod. The second transport roller is perpendicular to the rotating frame and is used to cooperate with the first transport roller to transport metal products.

[0007] In the aforementioned anti-deviation welding equipment for metal product processing, the stabilizing mechanism includes a third drive housing and a third transport roller. The third transport roller is rotatably connected to the third drive housing. The third drive housing is connected to the side plate via an electric push rod. The third transport roller is parallel to the rotating frame and is used to rotate the metal product at the welding position.

[0008] In the aforementioned anti-deviation welding equipment for metal product processing, a micro servo motor is installed inside the first drive housing, the second drive housing, and the third drive housing. The output end of the servo motor is fixedly connected to the transport roller. Multiple sets of conveying mechanism and stabilizing mechanism are provided, located on both sides of the center position of the base, for supporting the two metal products.

[0009] In the aforementioned anti-deviation welding equipment for metal product processing, an adjustment frame is installed at the upper end of the center position of the side plate via an electric push rod. Several fixed frames are installed on the side of the adjustment frame facing the metal product. Several fixed frames are rotatably connected to a grinding block, and the connection position is located in the middle section. The end of the grinding block is rotatably connected to the adjustment frame. An adjustment groove is opened on the side of the adjustment frame where the fixed frames are installed. The adjustment frame is inserted into the adjustment groove. The extension position and length of the adjustment frame are controlled by a push rod inside the adjustment groove.

[0010] In the aforementioned anti-offset welding equipment for metal product processing, the clamping mechanism includes a movable clamping frame, a limiting groove on the side wall of the rotating frame, a slider connected inside the limiting groove, an electric push rod installed on the inner wall of the limiting groove, and the output end of the electric push rod being fixedly connected to the slider. The side of the slider away from the rotating frame is connected to the movable clamping frame through the electric push rod.

[0011] In the aforementioned anti-deviation welding equipment for metal product processing, the movable clamping frame is precisely rotated by an internal micro motor, the movable clamping frame can stably hold the welding torch, and the side wall of the rotating frame can be freely fitted with locking buckles to fix the welding torch circuit.

[0012] In the aforementioned anti-offset welding equipment for metal product processing, the processing mechanism includes several processing blocks, which are connected to the end of a rotating frame via electric push rods. The processing blocks are arranged in an array around the rotating frame and their positions are offset from those of the movable snap-fit ​​frame. The rotating frame is internally rotatably connected by a turntable.

[0013] In the aforementioned anti-deviation welding equipment for metal product processing, only one side of the turntable is rotatably connected to the processing frame, and several turntables are respectively snapped together with a first turntable, a second turntable, and a third turntable on the side away from the processing frame.

[0014] In the aforementioned anti-deviation welding equipment for metal product processing, the first rotating disk is made of a heat-conducting material and its inner wall is equipped with heating elements; the second rotating disk is filled with welding anti-sticking agent and is equipped with electrically controlled small nozzles; the gaps between the electrically controlled small nozzles are filled with wiping cloths; and the third rotating disk is made of a flexible cleaning brush.

[0015] Compared with existing technologies, the advantages of this invention are:

[0016] 1. By arranging the rotating frame and multiple processing blocks, when welding metal parts with inconsistent pipe diameters, the pipe with the larger diameter is placed on the side closer to the mounting frame. Even if there are uneven steps at the connection, the rotating disk can still have a large area to contact the two metal pipes for relevant grinding and other pretreatment, while maintaining multiple internal and external supports.

[0017] 2. This invention uses rotating discs with different functions to perform different treatments. When the third rotating disc is installed, the brush contacts the welding position of the pipe for simple preliminary cleaning. When the second rotating disc is installed, it is used for spraying and evenly applying welding anti-sticking agent before welding, which is applied around the welding position and greatly reduces subsequent troubles. When the low-vibration disc is installed, it is used to preheat the welding position to prevent uneven weld caused by the thermal expansion of the metal during welding. Multiple rotating discs are supported on the inner wall of the pipe to provide stable clamping support and prevent deflection.

[0018] 3. Before welding, the invention controls the metal tube to reach the appropriate position, drives the electric push rod to drive the adjustment frame to the appropriate position, adjusts the grinding block to a certain angle to contact the metal tube opening, and controls the metal tube to rotate, grinding the metal tube at a specific angle at the welding position to facilitate subsequent welding. The generated debris will fall into the bottom collection box.

[0019] 4. When welding the outside of the pipe, the fixed welding gun position enables automated welding. The space inside the pipe is small, and the mounting bracket can slide freely to a suitable position so that the first rotating plate contacts the welding position on the inner wall of the pipe. The electric push rod and movable clamping bracket connected to the control slider can fix the position of the internal welding gun. With the rotation of the pipe, rapid automated welding work can also be achieved. Attached Figure Description

[0032] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0033] Example

[0034] Reference Figure 1-10 A metal product processing anti-deviation welding device includes a base 1, with side frames 2 fixedly connected to the top two sides of the base 1. A conveying mechanism and a stabilizing mechanism are installed on the side frames 2. A first drive housing 4 is installed above the base 1 via an electric push rod. A first transport roller 401 is rotatably connected inside the first drive housing 4. Metal pipes are placed above the first transport roller 401. The surface of the first transport roller 401 is covered with a rubber pad 5. A mounting frame 13 is slidably connected to the center of one end of the base 1. A rotating frame 14 is rotatably connected to the mounting frame 13. A processing mechanism is installed at the end of the rotating frame 14. A snap-fit ​​mechanism is installed on the side wall of the rotating frame 14. A collection box 3 is installed at the center of the upper side of the base 1.

[0035] The conveying mechanism includes a second drive housing 6 and a second transport roller 601. The second transport roller 601 is rotatably connected to the second drive housing 6. The second drive housing 6 is connected to the side plate 2 via an electric push rod. The second transport roller 6 is perpendicular to the rotating frame 14 and is used to cooperate with the first transport roller 401 to transport metal products. The main function of the first transport roller 401 and the second transport roller 601 is to control the metal pipe to reach the welding position and ensure a proper spacing.

[0036] The stabilizing mechanism includes a third drive housing 7 and a third transport roller 701. The third transport roller 701 is rotatably connected to the third drive housing 7. The third drive housing 7 is connected to the side plate 2 via an electric actuator. The third transport roller 701 is parallel to the rotating frame 14 and is used to rotate the metal product at the welding position. The rotation of the third transport roller 701 is used to realize the rotation of the pipeline. When rotating, the clamping pressure of the first transport roller 401 and the second transport roller 601 is loosened to a certain extent, reducing resistance and improving the driving effect.

[0037] The first drive housing 4, the second drive housing 6, and the third drive housing 7 are all equipped with micro servo motors. The output end of the servo motor is fixedly connected to the conveying roller. Multiple sets of conveying and stabilizing mechanisms are set up, located on both sides of the center position of the base 1, to support the two metal products. The rubber pad 5 deforms under the gravity of the pipe itself, which can increase the contact area and improve the conveying effect. The multi-point clamping of the pipe is always in a stable state. Multiple electric push rods work in coordination to make the center of the pipe coincide with the axis of the drive motor of the rotating frame 14.

[0038] An adjustment frame 8 is installed at the upper center of the side plate 2 via an electric push rod. Several fixed frames 10 are installed on the side of the adjustment frame 8 facing the metal product. Several fixed frames 10 are rotatably connected to a grinding block 9, and the connection position is located in the middle section. An adjustment frame 12 is rotatably connected to the end of the grinding block 9. An adjustment groove 11 is opened on the side of the adjustment frame 8 where the fixed frames 10 are installed. The adjustment frame 12 is inserted into the adjustment groove 11. The extension position and length of the adjustment frame 11 are controlled by a push rod inside the adjustment groove 11. The grinding block 9 is adjusted to a certain angle to contact the metal pipe opening. The third conveying roller 701 controls the rotation of the metal pipe to grind the welding position of the metal pipe at a specific angle. The generated debris will fall into the bottom collection box 3.

[0039] When welding the outside of the pipe, the welding gun can be directly fixed in a certain position, which is convenient to operate. The rotation of the two metal pipes can realize automated welding. The clamping mechanism includes a movable clamping frame 17, a rotating frame 14 with a side wall oil-limiting groove 15, a slider 16 connected inside the limiting groove 15, an electric push rod installed on the inner wall of the limiting groove 15 and the output end of the electric push rod is fixedly connected to the slider 16, and the side of the slider 16 away from the rotating frame 14 is connected to the movable clamping frame 17 through the electric push rod.

[0040] The movable clamp 17 is precisely rotated by an internal micro motor. The movable clamp 17 can stably hold the welding gun. The side wall of the rotating frame 14 can be freely fitted with locking buckles to fix the welding gun circuit. The space inside the pipe is narrow, and the mounting frame 13 can slide freely to a suitable position. The first rotating plate 20 can just contact the welding position on the inner wall of the pipe. The electric push rod connected to the control slider 16 and the movable clamp 17 can fix the position of the internal welding gun. With the rotation of the pipe, rapid welding work can be achieved.

[0041] The processing mechanism includes several processing blocks 18, which are connected to the end of the rotating frame 14 by electric push rods. The processing blocks 18 are arranged in an array around the rotating frame 14 and their positions are offset from the movable snap-fit ​​frame 17. The rotating frame 14 is internally rotatably connected by a turntable 19.

[0042] The turntable 19 is rotatably connected to the processing rack 18 on only one side. Several turntables 19 are respectively snapped to the first turntable 20, the second turntable 2, and the third turntable 25 on the side away from the processing rack 18. Even when there are uneven steps at the connection, the turntable can still have a large area to contact the two metal pipes for relevant processing.

[0043] The first rotating disc 20 is made of heat-conducting material and its inner wall is fitted with heating elements. The second rotating disc 22 contains welding anti-sticking agent and is equipped with electrically controlled small nozzles 24. Wiping cloths 23 are installed between the electrically controlled small nozzles 24. The third rotating disc 25 is made of flexible cleaning brushes. Several processing blocks 18 can perform different treatments. When the third rotating disc 25 is installed on the rotating disc 19, the brush contacts the welding position of the pipe for simple preliminary cleaning. When the second rotating disc 22 is installed on the rotating disc 19, it is mainly used for spraying and evenly applying welding anti-sticking agent before welding, applied around the welding position, greatly reducing subsequent troubles. When the low-vibration disc is installed on the rotating disc, it is used to preheat the welding position to prevent uneven weld caused by the thermal expansion of the metal during welding. Multiple rotating discs 19 are supported on the inner wall of the pipe, which can provide stable clamping support to prevent deflection.

[0044] In this invention, the device is used to support the welding of two metal pipe products. The metal pipe is placed above the first transport roller 401, and the second transport rollers 601 on both sides are controlled to contact the outer wall of the pipe. The rubber pad 5 deforms under the weight of the pipe itself, which can increase the contact area and improve the transport effect. The pipe is always in a stable state with multi-point clamping during transport. Multiple electric push rods work in coordination to make the center of the pipe coincide with the axis of the drive motor of the rotating frame 14.

[0045] To achieve further stable clamping, the third transport roller 701 is controlled to contact the pipe surface. The first transport roller 401 and the second transport roller 601 mainly control the metal pipe to reach the welding position and ensure a suitable distance. The rotation of the third transport roller 701 is used to realize the rotation of the pipe. When rotating, the clamping pressure of the first transport roller 401 and the second transport roller 601 is loosened to a certain extent, reducing resistance and improving the driving effect.

[0046] Before welding, the metal tube is controlled to reach the appropriate position. The electric push rod drives the adjustment frame 8 to reach the appropriate position. The grinding block 9 is adjusted to a certain angle to contact the metal tube opening. The third transport roller 701 controls the metal tube to rotate and grinds the metal tube at a specific angle at the welding position to facilitate subsequent welding. The generated debris will fall into the bottom collection box 3.

[0047] When welding the outside of the pipe, the welding gun can be directly fixed in a certain position, which is convenient to operate. The rotation of the two metal pipes can realize automated welding. The space inside the pipe is small, and the mounting bracket 13 can slide freely to a suitable position. The first rotating plate 20 can just contact the welding position on the inner wall of the pipe. The electric push rod connected to the control slider 16 and the movable clamping bracket 17 can fix the position of the internal welding gun. With the rotation of the pipe, rapid welding work can be achieved.

[0048] Several processing blocks 18 can perform different treatments. When the third rotating disc 25 is installed on the turntable 19, the brush contacts the welding position of the pipe for simple preliminary cleaning; when the second rotating disc 22 is installed on the turntable 19, it is mainly used for spraying and evenly applying welding anti-sticking agent before welding, applied around the welding position, greatly reducing subsequent troubles; when the low-vibration disc is installed on the turntable, it is used to preheat the welding position to prevent uneven weld caused by the thermal expansion of the metal during welding. Multiple turntables 19 are supported on the inner wall of the pipe, which can provide stable clamping support to prevent deflection.

[0049] When the two metal pipes have the same specifications, there is no need to pay attention to their placement. When the pipe diameters are different, place the pipe with the larger diameter on the side closer to the mounting bracket 13. Even if there are uneven steps at the connection, the rotating disk can still have a large area to contact the two metal pipes for relevant processing.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
