Description

Technical Field

[0001] The invention relates to the technical field of stainless steel welded pipe welding, and in particular to a stainless steel welded pipe welding processing device and system. Background Art

[0002] In modern industrial production and daily life, stainless steel welded pipes are widely used in many fields such as architectural decoration, medical equipment, petrochemicals, food and beverages, etc. due to their excellent corrosion resistance, high strength and good toughness. As the quality and performance requirements of stainless steel welded pipes in various industries continue to increase, the quality of welding processing technology and related devices and systems directly affect the production quality and efficiency of stainless steel welded pipes.

[0003] In the existing stainless steel pipe forming process, the welding process is as follows: first, bend the metal plate into a cylindrical shape. After shaping, put the cylindrical stainless steel into the equipment from the insertion end and place it on the support mechanism. At this time, the parts of the equipment are lowered and separated from the rod, so that the rod becomes a suspension rod for subsequent operations. Next, the welding part of the stainless steel pipe is facing upward, and the operator manually adjusts the position of the welding part through the control panel to accurately align it with the weld at the joint of the stainless steel pipe, and controls the welding part to move along the weld for welding. During the welding process, the slag collection + protection mechanism is located inside the stainless steel pipe and moves synchronously with the welding part. On the one hand, it takes over the slag generated during welding to prevent the slag from splashing everywhere and affecting the welding quality and working environment; on the other hand, it delivers protective gas to the welding area to prevent the welding part from coming into contact with the air at high temperature and causing oxidation, thereby ensuring the welding quality.

[0004] However, this welding method has certain defects. First, when the slag collection device is full of slag, it needs to be cleaned manually. Since the cleaning process requires the suspension of welding operations, production efficiency is reduced. Especially in large-scale production scenarios, frequent cleaning operations will cause serious delays in production progress. Second, when manually cleaning the slag, the operator needs to be in close contact with high-temperature slag and welding equipment, which poses safety risks such as burns and electric shock, threatening the personal safety of the operator. Third, manual cleaning of slag increases labor costs, and improper operation may cause slag to spill during the cleaning process, polluting the working environment and increasing environmental cleaning costs. Therefore, it is necessary to design a stainless steel welded pipe welding processing device and system.

[0005] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0020] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following combines the drawings and preferred embodiments to describe in detail the specific implementation manners, structures, features and their effects of the present invention as follows.

[0021] The following combines the drawings to detail the technical solutions provided by each embodiment of the present invention.

[0022] Refer to Figures 1 to 11 As shown, the embodiment of the present invention provides a stainless steel welded pipe welding processing device and system, including a welding component 1, a supporting component 2, a translation component 3, a support component 4, a cleaning component 5 and a detection component 6; The translation component 3 includes a support pipe 31, and an opening groove 32 is provided on the support pipe 31, and a displacement unit is arranged inside the opening groove 32. The displacement unit includes a first support body 312 fixedly installed at one end of the inner wall of the support pipe 31. A second forward and reverse motor 33 is fixedly installed on the first support body 312, and a first sprocket 34 is fixedly installed at the output end of the second forward and reverse motor 33; At the same time, a second support body 311 is fixedly installed at the other end of the inner wall of the support pipe 31. A second sprocket 313 is fixedly installed on the second support body 311. The second sprocket 313 and the first sprocket 34 are at the same horizontal position. A linear guide rail 36 is fixedly installed between the two first support bodies 312. A sliding frame 37 is slidably installed on the linear guide rail 36. Multiple groups of pulleys 38 are movably connected to both sides of the sliding frame 37. The sliding frame 37 slides along the linear direction of the linear guide rail 36 through the pulleys 38; And two sets of fixing parts 39 are fixedly installed on the bottom surface of the sliding frame 37, and a chain 35 is connected between the two sets of fixing parts 39, the first sprocket 34 and the second sprocket 313; When the translation assembly 3 works, the second forward and reverse motor 33 serves as the power source. When the motor is started, its output end drives the first sprocket 34 to rotate. Since the first sprocket 34 and the second sprocket 313 are in the same horizontal position and are connected by a chain 35, the rotation of the first sprocket 34 will drive the chain 35 to circulate between the two sprockets. The chain 35 is connected to the fixing part 39 on the bottom surface of the sliding frame 37. As the chain 35 moves, the sliding frame 37 is also driven. In this process, the linear guide 36 and the pulley 38 play a key guiding and supporting role. The linear guide 36 is fixedly installed between the two sets of first support bodies 312, providing an accurate linear guiding path for the movement of the sliding frame 37; the pulleys 38 on both sides of the sliding frame 37 are slidably connected to the linear guide 36, and the rolling of the pulleys 38 greatly reduces the friction force when the sliding frame 37 moves, enabling the sliding frame 37 to slide smoothly and smoothly along the linear direction of the linear guide 36.

[0023] When the second forward and reverse motor 33 rotates forward, the chain 35 drives the sliding frame 37 to translate in one direction along the linear guide 36; when the second forward and reverse motor 33 rotates in reverse, the chain 35 drives the sliding frame 37 to move in the opposite direction. By controlling the rotation direction and the number of rotation turns of the second forward and reverse motor 33, the translation distance and position of the sliding frame 37 can be accurately adjusted.

[0024] The cleaning assembly 5 includes a base plate 51 fixedly installed on the sliding frame 37, and spring members 52 are fixedly installed at positions near the four corners of the base plate 51. One ends of the two sets of spring members 52 are connected to a support bar 522, and right-angle grooves are formed on the mutually approaching surfaces of the two sets of support bars 522. A slag collection box 521 is placed between the two right-angle grooves. The slag collection box 521 is used to collect the welding slag generated during the welding of the stainless steel welded pipe, and limiting rods 53 are fixedly installed at the four corners of the slag collection box 521. The limiting rods 53 are inside the spring members 52 and one end penetrates through the base plate 51; When the cleaning assembly 5 works, it closely cooperates with the translation assembly 3 to operate together to achieve an efficient welding slag collection function. When the sliding frame 37 moves under the drive of the translation assembly 3, the base plate 51 fixedly installed on the sliding frame 37 moves synchronously, driving the entire cleaning assembly 5 to move below the welding position of the stainless steel welded pipe. When the welding slag generated during the welding process falls, the slag box 521 is responsible for receiving it. The spring member 52 plays a key role in this process. One end of the spring member 52 is connected to the base plate 51, and the other end is connected to the slag box 521. The spring member 52 has good elastic buffering performance. When the welding slag falls into the slag box 521, the impact force generated will cause the slag box 521 to press down. The spring member 52 is compressed and converts the impact force into its own elastic potential energy, thereby effectively mitigating the impact caused by the falling welding slag, preventing the slag box 521 from shifting due to severe vibration, and ensuring that the slag box 521 can stably collect the welding slag. The limiting rod 53 further ensures the stability of the movement of the slag box 521. The limiting rod 53 is fixed at the four corners of the slag box 521, located inside the spring member 52 and one end of which passes through the base plate 51. It provides guidance and limiting functions for the movement of the slag box 521, preventing the slag box 521 from deflecting or tilting during the compression or rebound of the spring member 52, ensuring that the slag box 521 always maintains the correct position to receive the welding slag, thereby improving the reliability and stability of the cleaning assembly 5. Meanwhile, a pipe clamp 54 is fixedly installed near the side of the base plate 51, and a pipe joint 55 is arranged inside the pipe clamp 54. A right-angle pipe 57 is fixedly installed at one end of the pipe joint 55. The right-angle pipe 57 has a right-angle end, and the right-angle end penetrates and engages with the bottom surface of the slag receiving box 521. Meanwhile, a through hole (not shown in the figure) adapted to the right-angle end is opened on the slag receiving box 521, and a sealing ring 58 is arranged at the contact position between the right-angle end and the through hole, and the sealing ring 58 enables the right-angle end to be tightly engaged in the through hole. Meanwhile, a hose 56 is fixedly installed at the other end of the pipe joint 55, and the hose 56 is suitable for connecting with an external protective gas cabinet to supply protective gas into the hose 56; During the operation of the cleaning assembly 5, the pipe joint 55 and the right-angle pipe 57 and hose 56 connected thereto constitute a shielding gas delivery system. When the cleaning assembly 5 moves to the lower part of the stainless steel welded pipe to receive the welding slag, the external shielding gas cabinet delivers shielding gas through the hose 56 connected to the pipe joint 55. The shielding gas first enters the pipe joint 55, and then flows to the slag receiving box 521 through the right-angle pipe 57. The right-angle end of the right-angle pipe 57 penetrates and engages in the through hole on the bottom surface of the slag receiving box 521, and the sealing ring 58 arranged at the contact position ensures the tight connection between the right-angle end and the through hole, effectively preventing the shielding gas from leaking.

[0025] During the welding process, the shielding gas enters the slag box 521 through the right-angle tube 57. On the one hand, a positive pressure environment is formed in the slag box 521, which helps to drive out the air in the slag box 521, reduce the chance of high-temperature welding slag contacting with oxygen, avoid further oxidation of welding slag, and reduce dust and other pollutants generated by welding slag oxidation; on the other hand, the shielding gas can play a certain cooling role on the high-temperature welding slag that has just fallen into the slag box 521, accelerate the solidification of welding slag, and facilitate subsequent processing. At the same time, the continuously delivered shielding gas can also prevent sparks, spatters, etc. generated during welding from entering the gap between the slag box 521 and the outside to a certain extent, ensuring the safety and stability of the entire cleaning component 5.

[0026] like Figures 9 - 10 As shown, a support portion 59 is fixedly installed near the side of the base plate 51, and the support portion 59 has a rotating shaft 510. At the same time, a sleeve portion 511 is movably sleeved on the rotating shaft 510. The sleeve portion 511 is fixedly connected to the side of the slag receiving box 521, and a second gear 512 is fixedly installed on one end of the two sets of sleeve portions 511 that are away from each other. At the same time, both ends of the rotating shaft 510 have limiting portions to limit the second gear 512 on the rotating shaft 510; At the same time, a collecting box 518 is fixedly mounted on the support tube 31 at a position close to the second sprocket 313, and a blocking cover 514 is fixedly mounted on the collecting box 518. A notch is arranged on the side of the blocking cover 514 facing the slag receiving box 521, and two sets of second racks 513 are fixedly mounted on the upper end surface of the collecting box 518. The second racks 513 are suitable for meshing with the second gear 512. At the same time, a notch groove 515 is provided on the blocking cover 514 for the second gear 512 to enter and continue to mesh with the second rack 513. It should be noted that when the sliding frame 37 moves under the drive of the translation assembly 3, the slag box 521 is driven to move synchronously. At this time, the two sets of second gears 512 on the slag box 521 gradually approach and contact and mesh with the second rack 513. At this time, the slag box 521 is close to the collecting box 518, and the slag box 521 is gradually driven to rotate along the axis of the rotating shaft 510. At the same time, it should be noted that the number of tooth blocks on the second rack 513 enables the slag box 521 to achieve a 130-degree rotation. At the same time, when the translation assembly 3 moves to the specified stroke, the slag box 521 completes a 130-degree rotation, and the two sets of second gears 512 are in the notch groove 515, which is suitable for introducing the welding slag collected on the slag box 521 into the slag box 521; The core purpose of the whole device is to realize the rotation of the slag box 521 during the movement of the sliding frame 37, so as to pour the welding slag collected in the slag box 521 into the collection box 518. This process mainly relies on the translation assembly 3 to provide power, and drives the slag box 521 to rotate around the rotating shaft 510 through the meshing transmission of the gear and the rack.

[0027] The translation component 3 serves as a power source to drive the movement of the sliding carriage 37. Since the base plate 51 is fixed to the sliding carriage 37 and the slag receiving box 521 is connected to the support portion 59 on the base plate 51 through the socket portion 511, the movement of the sliding carriage 37 will drive the synchronous movement of the slag receiving box 521.

[0028] When the slag receiving box 521 moves along with the sliding carriage 37, the two groups of second gears 512 on the side of the slag receiving box 521 gradually approach the second rack 513 on the collection box 518. When they come into contact, they start to mesh. The meshing of the second gear 512 and the second rack 513 is the key link to realize the rotation of the slag receiving box 521.

[0029] With the continuous meshing of the second gear 512 and the second rack 513, under the action of force, the slag receiving box 521 will rotate along the axis of the rotating shaft 510. The limiting portions at both ends of the rotating shaft 510 ensure that the second gear 512 will not fall off the rotating shaft 510, ensuring the stability of the transmission.

[0030] The number of teeth on the second rack 513 is carefully designed so that the slag receiving box 521 can achieve a rotation of 130 degrees. When the translation component 3 moves to the specified stroke, the slag receiving box 521 just completes a rotation of 130 degrees.

[0031] When the slag receiving box 521 completes a 130-degree rotation, the two groups of second gears 512 are located in the notch grooves 515 on the shield 514. At this time, the opening of the slag receiving box 521 faces the collection box 518, and the welding slag collected in the slag receiving box 521 will pour into the collection box 518 under the action of gravity. The shield 514 can prevent the welding slag from splashing out and plays a protective role.

[0032] In summary, the device is driven by the translation component 3, uses the gear-rack transmission to precisely control the rotation angle of the slag receiving box 521, realizes the automatic dumping process of the welding slag from the slag receiving box 521 to the collection box 518, and improves the efficiency of welding slag cleaning.

[0033] Specifically, a protective cover 516 is fixedly installed on the baffle 514. The protective cover 516 has a notch groove. When the sliding frame 37 moves under the drive of the translation assembly 3, it drives the slag receiving box 521 to displace synchronously. During this process, the second gear 512 on the slag receiving box 521 gradually meshes with the second rack 513 on the collection box 518, causing the slag receiving box 521 to rotate 130 degrees around the rotating shaft 510. After the slag receiving box 521 completes the rotation, its posture changes. At this time, the protective cover 516 on the baffle 514 begins to play a role. Since the notch groove of the protective cover 516 is precisely designed according to the shape of the slag receiving box 521 after flipping, and their shapes and sizes are mutually adapted, the slag receiving box 521 just fits into the notch groove after flipping. The notch groove provides a stable supporting force by closely fitting a specific part of the slag receiving box 521, effectively preventing the slag receiving box 521 from shaking or tilting due to gravity or external force, ensuring that the slag receiving box 521 remains stable when pouring welding slag, and ensuring that the welding slag can be smoothly poured into the collection box 518, realizing the all-round stable support and protection for the flipped slag receiving box 521.

[0034] Specifically, a drawer box 519 is slidably inserted into the side surface of the collection box 518. The drawer box 519 is used to collect the welding slag poured into the collection box 518. At the same time, a handle 520 is fixedly installed on the collection box 518; After the slag receiving box 521 rotates 130 degrees and pours the welding slag into the collection box 518, the welding slag is temporarily stored inside the collection box 518. At this time, the drawer box 519 serves as the final collection carrier for the welding slag and plays a key role. The drawer box 519 is connected to the side surface of the collection box 518 through a sliding insertion structure and can be pulled and moved inside the collection box 518.

[0035] When it is necessary to clean the welding slag in the collection box 518, the operator only needs to hold the handle 520 fixedly installed on the drawer box 519, apply an external force through the handle 520, and utilize the sliding characteristics of the sliding insertion structure to smoothly pull out the drawer box 519 from the side surface of the collection box 518. Since the drawer box 519 holds the welding slag in the collection box 518, the welding slag can be taken out together during the extraction process, realizing the centralized cleaning of the welding slag. After the cleaning is completed, the drawer box 519 is slid back into the collection box 518 through the handle 520 to continue to receive the subsequent welding slag, thereby ensuring that the entire welding slag collection system can operate continuously and stably, effectively improving the convenience and efficiency of the welding slag cleaning work.

[0036] Such as Figures 2 - 4As shown, specifically, the supporting component 2 includes a third support frame 21 for fixing one end of the support pipe 31, and a supporting part 22 is fixedly installed on the side of the third support frame 21. The supporting part 22 has an arc-shaped supporting groove with an opening (not shown in the figure). One end of the support pipe 31 is fixed in the arc-shaped supporting groove. At the same time, a tripod 24 is arranged on one side of the third support frame 21. One end of the support pipe 31 has a rod end 310. The tripod 24 is used to support the rod end 310. The tripod 24 has a pipe orifice, and a first hydraulic cylinder is arranged at the bottom end of the inner wall of the pipe orifice. A support rod 25 is fixedly installed at the output end of the first hydraulic cylinder. One end of the support rod 25 is fixedly installed with a holding part 26. A second supporting groove is formed on the holding part 26, and the second supporting groove is suitable for supporting the rod end 310; It should be noted that in the initial state, the first hydraulic cylinder is in the starting and extending state. The piston rod pushes the support rod 25 to move upward, so that the second supporting groove on the holding part 26 is coaxial with the arc-shaped supporting groove of the supporting part 22, laying a foundation for subsequent installation and welding work.

[0037] When installing the stainless steel pipe to be welded, the operator controls the first hydraulic cylinder to reset and contract. The piston rod drives the support rod 25 and the holding part 26 to descend synchronously, so that the holding part 26 is separated from one end of the support pipe 31. At this time, the support pipe 31 loses the upper restraint and becomes a suspended rod state. This state provides an operating space for the installation of the stainless steel pipe. The staff can easily sleeved the stainless steel pipe on the support pipe 31 and adjust it to the correct position with the welding part facing upward.

[0038] After the installation is completed, the first hydraulic cylinder is started again to make it extend and push the holding part 26 to rise until the second supporting groove fits the other end of the support pipe 31 again, restoring the support for both ends of the support pipe 31.

[0039] As Figure 3 and Figure 5 As shown, specifically, the support component 4 includes a bottom plate 41 arranged at the lower end of the support pipe 31. The third support frame 21 and the tripod 24 are respectively fixedly installed at positions close to both ends on the bottom plate 41. Three groups of supporting ends are equidistantly installed on the bottom plate 41. The supporting end includes a base body 42 fixedly installed on the bottom plate 41. There are supporting ends 43 at positions close to both sides of the base body 42. A third forward and reverse motor 47 is fixedly installed at one end of the base body 42. At the same time, a docking part (not marked in the figure) is fixedly installed at a position close to the other end of the base body 42; A first lead screw 48 is fixedly installed at the output end of the third forward and reverse motor 47. One end of the first lead screw 48 is connected to the docking part through a bearing. Two sets of helical grooves with opposite helix directions are symmetrically arranged on the first lead screw 48. Two carriage 45 are threadedly connected to the two sets of helical grooves respectively. The carriage 45 is located between the two support ends 43. Restricting ends (not marked in the figure) are fixedly installed on both sides of the carriage 45. At the same time, a waist-shaped groove 44 which is adapted to the width of the restricting end and for the linear movement of the carriage 45 is formed on the support end 43. A support wheel 46 is rotatably installed on the carriage 45, and the support wheel 46 is adapted to contact the surface of the stainless steel pipe to be welded. The third forward and reverse motor 47 serves as a power source. After starting, it drives the first lead screw 48 to rotate. The two sets of reverse helical grooves symmetrically distributed on the first lead screw 48 cause the two carriages 45 threadedly connected thereto to move towards or away from each other. When the motor rotates forward, the carriages 45 approach each other along the lead screw; when the motor rotates in reverse, they move away from each other. The restricting ends on both sides of the carriage 45 cooperate with the waist-shaped grooves 44 of the support end 43 to ensure that the carriage 45 can only translate linearly and avoid deviation.

[0040] The support wheel 46 installed on the carriage 45 adjusts its height as the distance between the carriages 45 changes. When the distance between the two carriages 45 drives the support wheel 46 to decrease, the support wheel 46 lifts the stainless steel pipe from both sides, increasing the support position; conversely, when the distance between the carriages 45 increases, the supporting force of the support wheel 46 on the steel pipe is dispersed, resulting in a decrease in the support position of the steel pipe. By precisely controlling the rotation direction and speed of the third forward and reverse motor 47, the precise adjustment of the distance between the support wheels 46 can be achieved, thereby meeting the stable support requirements for stainless steel pipes of different diameters.

[0041] As Figure 2 、 Figure 8 and Figure 11 shown, specifically, the detection assembly 6 includes two sets of columns 61 fixedly installed on the bottom plate 41. A fourth forward and reverse motor 62 is fixedly installed at the top of the column 61. A second lead screw 63 is fixedly installed at the output end of the fourth forward and reverse motor 62. One end of the second lead screw 63 is connected to one end of the column 61 through a bearing. Two sets of helical grooves with opposite helix directions are provided on the second lead screw 63. Two sliding seats 65 are threadedly connected to the two sets of helical grooves respectively. At the same time, two sets of guide rods 64 are fixedly installed on the column 61. The guide rods 64 are located on both sides of the second lead screw 63, and the sliding seat 65 is movably sleeved on the two sets of guide rods 64; And a connecting plate 66 is fixedly installed between the two horizontally arranged sliding seats 65, and here Figure 11As a reference, the connecting plate 66 at the upper end is defined as the first connecting plate, and the connecting plate 66 at the lower end is defined as the second connecting plate, and a laser sensor 67 is fixedly installed at the positions near the two ends of the first connecting plate, and the laser beam emitting end is kept at the same height as the bottom surface of the first connecting plate, and at the same time, a butt end (not shown in the figure) for butt-jointing the laser beam is installed at a corresponding position on the second connecting plate; A pressure sensor 68 is embedded and installed on the first connecting plate and the second connecting plate on the side that contacts the stainless steel pipe to be tested. A spring body (not shown in the figure) is connected between the pressure sensor 68 and the connecting plate 66. It should be noted that when the pressure sensor 68 contacts the surface of the stainless steel pipe to be welded, the pressure sensor 68 is pressed to squeeze the spring body, and when the spring body is squeezed to the limit position, it is at the same height as the surface of the second connecting plate; The height adjustment of the support wheel 46 depends on the diameter data of the stainless steel pipe measured by the detection component 6, and the data is processed and the command is output through a computing device (such as a PLC controller, etc.). The specific process is as follows: The diameter data of the stainless steel pipe measured by the laser sensor 67 is transmitted to the computing device in real time. At the same time, the system presets the initial distance between the support wheel 46 and the bottom surface of the support pipe 31 (such as 150 mm), the outer diameter of the support pipe 31 (such as 100 mm) and other parameters which have been stored in the computing device.

[0042] The calculation device performs data calculation according to the preset formula "support wheel 46 upward movement distance = (diameter of the stainless steel pipe to be detected - diameter of the support pipe 31) ÷ 2". For example, when the diameter of the stainless steel pipe is measured to be 200 mm, the calculation device automatically obtains "(200-100) ÷ 2 = 50 mm", that is, the support wheel 46 needs to be moved up 50 mm.

[0043] Based on the upward distance, the calculation device further uses the formula "support wheel 46 target height = initial distance - upward distance" to obtain the final distance between the support wheel 46 and the bottom surface of the support tube 31. Taking the above data as an example, "150-50=100mm" is used as the target position of the support wheel 46.

[0044] The computing device converts the target height data into control instructions and sends them to the third forward and reverse motor 47 of the support assembly 4. The third forward and reverse motor 47 drives the first lead screw 48 to rotate, driving the carriage 45 and the support wheel 46 closer to the support tube 31. The support tube 31 is provided with a strain pressure sensor, which real-time monitors the pressure change between the support wheel 46 and the support tube 31 and feeds the data back to the computing device. When the strain pressure sensor detects that the pressure reaches the preset threshold (indicating that the support wheel 46 has contacted the support tube 31 and reached the target height), the computing device immediately controls the third forward and reverse motor 47 to stop operating, completing the precise positioning of the support wheel 46, so that there is a material receiving distance between the inner wall of the stainless steel tube to be detected and the slag receiving box 521.

[0045] As Figures 1 - 2 shown, specifically, the welding assembly 1 includes two groups of first support frames 11 arranged on one side of the bottom plate 41. A support platform 12 is connected between the two groups of first support frames 11, and a first moving unit is installed on the support platform 12. The first moving unit includes two groups of slide rails 13 fixedly installed on the support platform 12 near both ends, and a first rack 14 is fixedly installed on the support platform 12 and located between the two groups of slide rails 13. A first slide plate 16 is slidably installed on the two groups of slide rails 13. A first forward and reverse motor 17 is fixedly installed on the first slide plate 16. The output end of the first forward and reverse motor 17 has a first gear (not shown in the figure), which meshes with the first rack 14. A second support frame 18 is fixedly installed on the first slide plate 16, and a second moving unit 19 is installed on the second support frame 18. The second moving unit 19 is adapted to perform vertical movement, and the first moving unit is adapted to perform horizontal movement. The second moving unit 19 has a similar structure to the first moving unit. Here, the first slide plate 16 of the second moving unit 19 is defined as the second slide plate. A laser welding arm 110 is fixedly installed on the second slide plate, and the laser welding arm 110 is adapted to weld the stainless steel tube installed on the support tube 31. The first forward and reverse motor 17 is fixedly installed on the first slide plate 16 as a power source. When the motor is started, the first gear at its output end starts to rotate. Since the first gear meshes with the first rack 14 on the support platform 12, according to the gear-rack transmission principle, the rotational motion of the first gear is converted into a linear motion.

[0046] The first sliding plate 16 provides guidance and support for horizontal movement through its sliding connection with two sets of slide rails 13. The slide rails 13 are fixedly installed at positions near both ends of the support platform 12, restricting the movement direction of the first sliding plate 16 and enabling it to move horizontally only along the extension direction of the slide rails 13. As the first forward and reverse motor 17 rotates, the first gear rolls on the first rack 14, driving the first sliding plate 16 to smoothly displace horizontally on the slide rails 13, thereby achieving the movement control of the first moving unit in the horizontal direction.

[0047] The second moving unit 19 adopts a structure similar to that of the first moving unit, and its core component, the second sliding plate, is installed on the first sliding plate 16. The second moving unit 19 also has a similar structure of slide rails 13, rack, and motor gear drive. When the motor of the second moving unit 19 starts, the gear at the output end of the motor meshes with the internal rack, converting the rotational motion into a linear motion and pushing the second sliding plate to move in the vertical direction.

[0048] The laser welding arm 110 fixedly installed on the second sliding plate adjusts its position in the vertical direction as the second sliding plate moves vertically. Combining with the horizontal movement achieved by the first moving unit, the laser welding arm 110 can be flexibly positioned in three-dimensional space and accurately aligned with the welding part of the stainless steel pipe installed on the support pipe 31. Through the coordinated control of the motors of the two moving units by the control system, the laser welding arm 110 can perform a compound motion in the horizontal and vertical directions according to a preset path or based on the actual position of the stainless steel pipe to complete the welding work of the stainless steel pipe.

[0049] Working principle: The stainless steel welded pipe welding processing device and system achieve fully automated operation from pipe installation, inspection, welding to slag cleaning through the coordinated operation of six major components: welding, supporting, translating, supporting, cleaning, and detecting. Specifically, the supporting component 2 uses the third support frame 21 and the tripod 24 in cooperation with the first hydraulic cylinder to achieve the stable installation of the support pipe 31 and the convenient socket connection of the stainless steel pipe to be welded; the detecting component 6 drives the second lead screw 63 through the fourth forward and reverse motor 62, driving the sliding seat 65 and the connecting plate 66 closer to the pipe. After the pressure sensor 68 triggers a stop signal, the laser sensor 67 accurately measures the diameter of the stainless steel pipe and transmits the data to the computing device. The computing device adjusts the operation of the third forward and reverse motor 47 in the support component 4 according to a preset formula, driving the carriage 45 through the first lead screw 48, so that the support wheels 46 accurately adjust the height according to the pipe diameter to ensure the stable support of the pipe.

[0050] The welding assembly 1 is powered by the first forward and reverse motor 17, and is guided by the rack and pinion drive and the slide rail 13 to drive the first sliding plate 16 to move horizontally. The second moving unit 19 achieves vertical movement with a similar structure. The two cooperate to accurately position the laser welding arm 110 in three-dimensional space to complete the welding task. The second forward and reverse motor 33 of the translation assembly 3 drives the first sprocket 34 and the chain 35 to move, and is guided by the linear guide 36 and the pulley 38 to drive the sliding frame 37 to move horizontally, thereby driving the cleaning assembly 5 to operate synchronously. The slag receiving box 521 of the cleaning assembly 5 stably receives the welding slag under the action of the spring member 52 and the limiting rod 53. At the same time, the protective gas system connected by the pipe joint 55 prevents the welding slag from oxidizing; when the sliding frame 37 moves to the designated position, the second gear 512 on the slag receiving box 521 meshes with the second rack 513 of the collection box 518 to achieve a 130-degree flip, pouring the welding slag into the collection box 518, and the final cleaning is completed by the drawer box 519.
