Description

Technical Field

[0001] The invention relates to the technical field of welding machine tool parts, and in particular to a welding forming system suitable for manufacturing machine tool parts. Background Art

[0002] In the process of machine tool parts production, it is often necessary to process machine tool parts by welding. Among them, pipe fittings are widely used in the assembly and production process of machine tools.

[0003] In the process of welding pipe fittings, for some circular pipe fittings, the plate is usually bent to make its cross section circular and then welded at the joint. However, for some rectangular tubes with higher precision, especially large-walled thick rectangular tubes with square cross sections, the thick-walled plate is processed by bending to shape it into a rectangular tube with a square cross section. When the plate is thicker, the plate is bent to ninety degrees, and its corners are usually arc-shaped. At this time, the corners of this rectangular tube have low precision, which makes the rectangular tube formed by bending and welding low in precision, and it is difficult to meet the high-precision requirements during machine tool assembly production. Further cutting processing is usually required, which makes the production process of this large-walled thick rectangular tube with a square cross section more complicated. In addition, flanges or other connectors are usually welded on the outside of the pipe fittings included in the machine tool parts. After the traditional welding device completes the welding of the pipe fittings, it is necessary to transport the pipe fittings to the processing step of welding with the connectors, etc., which makes the processing steps of the entire machine tool parts longer. In this process, the pipe fittings still need to be limited and fixed again, which makes the production efficiency of the entire production line for welding machine tool parts low.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention sets a guide component, and multiple positioning rods are opened outward to contact the inner wall of the pipe fitting. When multiple nozzles in the first laser welding machine weld the connecting seam inside the pipe fitting, the first laser welding machine is always located at the center position inside the pipe fitting, thereby ensuring the distance between the nozzle and the connecting seam of the pipe fitting, and also ensuring the welding quality at the connecting seam of the pipe fitting. In the welding process, two detection plates arranged at the ends of the positioning rods can measure the angle between the pipe walls on both sides of the connecting seam after the first laser welding machine completes the welding of the connecting seam of the pipe fitting. Defective products generated in the welding process can be discovered in time, thereby ensuring the quality of the finished thick-walled rectangular pipe fittings after welding, and preventing the finished rectangular pipe fittings that are deformed due to the stress of the material itself from entering the market.

[0020] The present invention sets a conveying assembly, and through the deformation of the movable plate and two rotating plates in the conveying assembly after being combined, the conveying assembly can be suitable for conveying rectangular tubes of various sizes. In the process of combining four rectangular blocks into rectangular tube fittings, the adjustment base movably connected to the movable plate can adjust the position of the conveying assembly through its existing internal structure, and then adjust the position of the rectangular blocks clamped by the clamping plate, so that the corresponding wall surfaces of the four rectangular blocks are aligned, and then the four rectangular blocks are preliminarily combined into corresponding rectangular tube fittings. The four groups of conveying assemblies after the rotating plate is rotated and deformed are also suitable for clamping and conveying the outer wall of the circular tube fitting, wherein the rotating plate can contact the outer wall of the circular tube fitting after rotation, so that the multiple first rollers arranged on the outer wall of the rotating plate convey the circular tube fitting to the inside of the device after rotation.

[0021] The present invention can tension and fix the inside of the two ends of the pipe fitting after welding by setting the first supporting assembly and the second supporting assembly. Then, by rotating the rotating ring of the pipe fitting, the whole pipe fitting after welding can be driven to rotate synchronously, so that the flange and other connecting parts arranged on the outside of the pipe fitting can be welded to the pipe fitting body after welding. In addition, during the use of the device, when feeding round pipe fittings or square pipe fittings into the inside of the device, the second supporting assembly can provide auxiliary support for the end of the pipe fitting.

[0022] The present invention arranges an auxiliary component. When the rectangular pipe fitting is transported to the inside of the device after welding, the lifted support plate can support the bottom surface of the pipe fitting. At the same time, the base slides toward one end of the base plate where a lifting seat is arranged, so that the pipe fitting can move to the inside of the device in coordination with the conveying speed of the conveying component. Under the action of the base and the support plate, the end of the pipe fitting after welding can be prevented from sinking, thereby affecting the welding in the subsequent process. At the same time, when the first support component and the second support component respectively support the two ends of the pipe fitting after welding, the support plate located under the pipe fitting is rotated and re-stored in the rectangular groove. At this time, the slide groove arranged on the upper surface of the base is docked with the docking groove, and the sliding seat arranged on the upper surface of the base can slide on the upper surface of the base through the slide groove and the support plate. Then, the second laser welding machine arranged inside the sliding seat can weld the flange and other connecting parts arranged on the outside of the pipe fitting to the pipe fitting body.

[0040] The first laser welding machine 6 specifically includes a laser welding machine body 601 slidably connected to the slide rail 4, a laser welding gun neck 602 is fixedly connected to the end of the laser welding machine body 601, a guide assembly 11 is provided on the outer wall of the laser welding gun neck 602, a rotating seat is rotatably installed at the end of the laser welding gun neck 602, and four symmetrically arranged first connecting rods 603 are fixedly connected to the rotating seat, and nozzles 604 are fixedly installed at the ends of the multiple first connecting rods 603;

[0041] The guide assembly 11 includes a cylinder 1101 fixedly connected to the laser welding machine body 601, a fixed ring 1105 is fixedly installed on one end of the cylinder 1101 away from the laser welding machine body 601, and a sliding ring 1102 is slidably installed on the other end close to the laser welding machine body 601, four equally spaced expansion rods 1103 are rotatably installed on the sliding ring 1102, a positioning rod 1104 is rotatably installed on the fixed ring 1105 at a position corresponding to the expansion rod 1103, and the end of the expansion rod 1103 is rotatably connected to the corresponding position on the positioning rod 1104, the ends of the plurality of positioning rods 1104 are rotatably connected to a second connecting rod 1106, the end of the second connecting rod 1106 is rotatably connected to a connecting shaft 1107, both sides of the connecting shaft 1107 are rotatably connected to detection plates 1108, and the ends of the two detection plates 1108 corresponding to the connecting shaft 1107 are fixedly installed with rotating gears 1109, and the two rotating gears 1109 are meshingly connected;

[0042] According to the number of cracks to be welded, the user can also choose one, two or three of the four groups of first connecting rods 603 and nozzles 604 for welding. The specific usage depends on the actual situation. The three groups of fixing components 12 set in the fixing frame 2 can adsorb the large-walled rectangular blocks located on the top and both sides, wherein the large-walled rectangular blocks set at the bottom can be placed on the conveying component 7. Then, the four groups of conveying components 7 can respectively clamp the four large-walled rectangular blocks so that the four large-walled rectangular blocks are combined into a thick-walled rectangular tube. Then, the first laser welding machine 6 set at the end of the slide rail 4 can weld the four connecting seams of the thick-walled rectangular tube. During the welding process, the rotating machine 602 set at the end of the laser welding gun neck When the seat rotates, the first connecting rod 603 fixedly connected to the rotating seat can be rotated to a position corresponding to the thin strip connection seam of the thick-walled rectangular tube. Under the action of the four groups of conveying components 7, the thick-walled rectangular tube after preliminary assembly can be continuously conveyed to the inside of the device. In this process, the nozzle 604 arranged at the end of the first connecting rod 603 can continuously weld the connection seam of the thick-walled rectangular tube until the connection seam of the entire pipe is welded. When the nozzle 604 welds the connection seam of the pipe, the positioning rod 1104 arranged at the corresponding position of the nozzle 604 is opened to contact with the four corners of the pipe under the action of the expansion rod 1103. At this time, the four positioning rods 1104 are opened at the same angle, so that the neck 60 of the laser welding gun can be welded. 2 is always in the center position inside the pipe fitting, thereby ensuring that the four sets of nozzles 604 always maintain accurate welding of the connection seams at the four corners of the rectangular pipe fitting, wherein the second connecting rod 1106 arranged at the end of the positioning rod 1104 can be rotated and adjusted according to the inclination angle of the positioning rod 1104. When the second connecting rod 1106 is rotated, the connecting shaft 1107 arranged at the end of the second connecting rod 1106 also rotates synchronously to coincide with the connection seam of the rectangular pipe fitting. At this time, the detection plates 1108 rotatably connected on both sides of the connecting shaft 1107 can fit with the inner walls of both sides of the rectangular pipe fitting after welding, and the angle between the two detection plates 1108 is ninety degrees. During the relative movement between the rectangular pipe fitting and the first laser welding machine 6, The detection plate 1108 can detect the angles at the four corners of the rectangular pipe fittings after welding. If the angle between the two rectangular blocks becomes smaller, the rotating gears 1109 fixedly connected to the ends of the two detection plates 1108 will squeeze each other. An angle sensor is provided on the tooth surface of the rotating gear 1109. When the rotating gears 1109 squeeze each other, the sensor can transmit the reading to the controller, and finally reflect it on the display panel of the device, thereby ensuring the quality of the finished thick-walled rectangular pipe fittings after welding, and avoiding the finished rectangular pipe fittings that are deformed due to the stress of the material itself from entering the market. In the above process, by adjusting the opening angle of the positioning rod 1104, it can be used in conjunction with thick-walled rectangular pipe fittings with square cross-sections of different sizes.

[0043] As a technical optimization solution of the present invention, the conveying assembly 7 includes an adjustment base slidably connected to the two top guide rods 202 or the side wall guide rods 203, a movable plate 701 is movably installed on the adjustment base, both ends of the movable plate 701 are rotatably installed with rotating plates 702, a plurality of mounting grooves 704 are opened on the rotating plate 702, a first roller 705 is rotatably installed inside the plurality of mounting grooves 704, a clamping plate 703 is rotatably installed at one end of the two rotating plates 702 away from the movable plate 701, the cross section of the clamping plate 703 is L-shaped, and the two clamping plates 703 are arranged opposite to each other;

[0044] According to the size of the rectangular block used for welding the rectangular pipe fittings, the conveying assembly 7 arranged on the side of the pipe fittings can be deformed according to the actual situation of the pipe fittings, wherein, when the height of the rectangular block is greater than the length of the entire conveying assembly 7, the movable plate 701 and the two rotating plates 702 are in the same plane, then the outer walls of the movable plate 701 and the rotating plate 702 are in contact with the outer walls of the rectangular pipe fittings after the preliminary combination, and under the rolling action of the second roller 708 and the first roller 705 respectively arranged on the movable plate 701 and the rotating plate 702, the pipe fittings are continuously conveyed to the inside of the device for welding, and when the height of the rectangular block is less than the length of the entire conveying assembly 7, the rotating plates 702 arranged at both ends of the movable plate 701 rotate, and at the same time, the clamping plates 703 arranged at the ends of the two rotating plates 702 rotate, and the two clamping plates 703 after rotation can limit the upper and lower edges of the rectangular block respectively, at this time, the two clamping plates 703 arranged on the outer wall of the movable plate 701 The block adjustment plate 707 rotates outward, and when the second roller 708 set at the end of the adjustment plate 707 contacts the outer wall of the rectangular block, the combined rectangular pipe fittings can also be transported by rotating multiple second rollers 708. It is worth mentioning that in the process of combining the four rectangular blocks into rectangular pipe fittings, the adjustment base movably connected to the movable plate 701 can adjust the position of the conveying component 7 through its existing internal structure, and then adjust the position of the rectangular block clamped by the clamping plate 703, so that the corresponding wall surfaces of the four rectangular blocks are aligned, and then the four rectangular blocks are preliminarily combined into corresponding rectangular pipe fittings. The four groups of conveying components 7 after the rotating plate 702 is rotated and deformed are also suitable for clamping and conveying the outer wall of the circular pipe fitting, wherein the rotating plate 702 can contact the outer wall of the circular pipe fitting after rotation, so that the multiple first rollers 705 set on the outer wall of the rotating plate 702 convey the circular pipe fittings to the inside of the device after rotation.

[0046] When the rectangular blocks that make up the rectangular tube are clamped and limited by the two clamping plates 703, the multiple first rollers 705 set on the rotating plate 702 cannot contact the rectangular blocks. At this time, by driving the two adjustment plates 707 to rotate outward, the multiple second rollers 708 set at the end of the adjustment plate 707 are in contact with the outer wall of the rectangular blocks. The friction force between the second rollers 708 and the outer wall of the rectangular blocks can drive the rectangular blocks to be continuously transported into the device.

[0048] When the rectangular pipe is transported to the inside of the device after being welded, the two support rods 803 arranged at the upper end of the base 801 can be lifted upward under the action of the first electric telescopic rod 805, and the lifted support plate 804 can support the bottom surface of the pipe. At the same time, the base 801 slides toward the end of the bottom plate 1 where the lifting seat 3 is provided, so that the pipe can move to the inside of the device at the conveying speed of the conveying component 7. Under the action of the base 801 and the support plate 804, the end of the pipe after welding can be prevented from sinking, thereby affecting the welding in the subsequent process.

[0049] As a technical optimization solution of the present invention, a docking groove 806 is provided on the upper end surface of the support plate 804, and slide grooves 807 are provided on both sides of the docking groove 806 on the upper end surface of the base 801, and the slide grooves 807 are arranged flush with the docking groove 806, and a sliding seat 808 is arranged at a position corresponding to the slide groove 807 at one end of the upper surface of the base 801, and an embedding groove 809 is provided on the sliding seat 808, and the second laser welding machine 810 is rotatably connected inside the embedding groove 809, and the sliding seat 808 is slidably connected to the base 801 through the slide groove 807;

[0050] When the first support assembly 5 and the second support assembly 10 respectively support the two ends of the pipe after welding, the support plate 804 located below the pipe is rotated and re-stored in the rectangular groove 802.

The sliding seat 808 arranged on the upper surface of the base 801 can slide on the upper surface of the base 801 through the slide groove 807 and the support plate 804. The second laser welding machine 810 is rotatably installed on the sliding seat 808. When the sliding seat 808 slides parallel to the base 801, and then cooperates with the first support assembly 5 and the second support assembly 10 to drive the rectangular pipe to rotate, the second laser welding machine 810 can be used to weld the connecting piece set at the end of the rectangular pipe with a square cross-section to the pipe body. When the sliding seat 808 is fixed, the second laser welding machine 810 is adjusted so that its end contacts the corresponding position of the outer wall of the circular pipe. Then, the circular pipe body and connecting pieces such as flanges can be welded through the first support assembly 5 and the second support assembly 10.

[0051] As a technical optimization solution of the present invention, a first support assembly 5 is provided on the outer wall of one end of the slide rail 4 close to the lifting seat 3. The first support assembly 5 includes a connecting block 504 fixedly connected to the slide rail 4. The outer wall of the connecting block 504 is rotatably connected to a rotating ring 501.

[0052] When the end of the pipe fitting is transported to the first supporting assembly 5, the tensioning rod 502 arranged on the outer wall of the rotating ring 501 rotates and opens outward. After the multiple tensioning rods 502 are opened outward, for a rectangular pipe fitting with a square cross-section, the ends of the tensioning rod 502 abut against the four corners of the inner wall of the rectangular pipe fitting. For a circular pipe fitting with a circular cross-section, the contact block 503 arranged at the end of the tensioning rod 502 can abut against the inner wall of the circular pipe fitting.

[0054] When the multiple tensioning rods 502 in the first support assembly 5 are opened to tension and support one end of the pipe fitting after welding, the second support assembly 10 arranged at the other end of the pipe fitting can support the other end of the pipe fitting, wherein the ends of the two lifting rods 1001 connected to the extension plate 9 are brought close to each other, and the second electric telescopic rod 1003 equipped with the auxiliary plate 1004 can be lifted upward to be coaxial with the pipe fitting and the first support assembly 5, and then the telescopic end of the second electric telescopic rod 1003 is extended, and the end of the second electric telescopic rod 1003 equipped with the auxiliary plate 1004 can be extended into the end of the pipe fitting. The end of the rod 1003 extends into the interior of the pipe, and the multiple auxiliary plates 1004 can support the interior of the pipe after being opened. Under the cooperation of the multiple tensioning rods 502 and the multiple auxiliary plates 1004, the two ends of the welded pipe can be supported and fixed. At this time, the multiple positioning rods 1104 arranged outside the first laser welding machine 6 are retracted until their ends are not in contact with the inner wall of the pipe. By rotating the pipe rotating ring 501, the welded pipe can be driven to rotate synchronously as a whole. It is worth mentioning that when loading round pipes or square pipes into the interior of the device, the end of the pipe can be auxiliary supported by the second support assembly 10.

[0055] As a technical optimization scheme of the present invention, three groups of fixing components 12 are slidably installed on the fixing frame 2, and the fixing component 12 includes a movable seat 1201 slidably connected to the fixing frame 2, and a third electric telescopic rod 1202 is fixedly installed on the movable seat 1201, and a suction cup 1203 is fixedly connected to the output end of the third electric telescopic rod 1202; the movable seat 1201 can slide on the top guide rod 202 or the side wall guide rod 203, and under the cooperation of the third electric telescopic rod 1202 and the suction cup 1203, the positions of the four rectangular blocks can be preliminarily fixed before the conveying component 7 clamps the rectangular blocks that constitute the rectangular square tube. After the conveying component 7 fixes the rectangular blocks, the suction cup 1203 is separated from the outer wall of the rectangular block, and the third electric telescopic rod 1202 is extended and cooperated with the suction cup 1203 to clamp and fix the flange and other connectors sleeved on the outside of the pipe fitting, and according to the actual situation, the flange and other connectors are clamped and transported to the corresponding position of the outer wall of the pipe fitting and play an auxiliary fixing role for the flange and other connectors.

[0056] As a technical optimization solution of the present invention, the number of tensioning rods 502 is the same as the number of positioning rods 1104, and the ends of multiple tensioning rods 502 are rotatably installed with contact blocks 503; in this technical solution, the number of tensioning rods 502, auxiliary plates 1004 and positioning rods 1104 corresponds, and when the device is applied to the welding of other pipe fittings with regular polygonal cross-sections, the remaining thick-walled pipe fittings with regular polygonal cross-sections can be welded by increasing or decreasing the number of positioning rods 1104, and the contact block 503 arranged at the end of the tensioning rod 502 can adaptively fit the inner wall of the pipe fitting, thereby increasing the contact area between the end of the tensioning rod 502 and the inner wall of the pipe fitting.

[0057] As a technical optimization solution of the present invention, the number of conveying components 7 is four groups, and three groups of conveying components 7 are located on the fixed frame 2, and the fourth group of conveying components 7 is located on the upper end surface of the base plate 1 and corresponds to the other three groups of conveying components 7; the four groups of conveying components 7 correspond to four positions outside the pipe fittings, respectively, and the pipe fittings are conveyed through full contact between the conveying components 7 and the outer wall of the pipe fittings.

[0058] When the present invention is in use, the first laser welding machine 6 located on the slide rail 4 can extend into the interior of the pipe to weld the pipe, wherein the device can be applied to weld pipes of various shapes, wherein the device shown in the technical scheme diagram can weld high-precision rectangular pipes and round pipes with square cross-sections, etc., and in the actual application process, by increasing or decreasing the number of positioning rods 1104, the remaining thick-walled pipes with regular polygonal cross-sections can be welded;

[0059] When the device needs to weld a thick-walled rectangular tube with a square cross-section, the device can simultaneously weld the connection seams of the four rectangular blocks that make up the rectangular tube. At this time, the four groups of first connecting rods 603 and nozzles 604 in the first laser welding machine 6 can all be put into welding working state. According to the number of cracks to be welded, the user can also choose one group, two groups or three groups of the four groups of first connecting rods 603 and nozzles 604 for welding. The specific usage method depends on the actual situation. The three groups of fixing components 12 set in the fixing frame 2 can adsorb the large-walled thick rectangular blocks located on the top and both sides, wherein the large-walled thick rectangular blocks set at the bottom can be placed on the conveying component 7. Then, the four groups of conveying components 7 can respectively clamp the four large-walled thick rectangular blocks so that the four large-walled thick rectangular blocks are combined into a thick-walled rectangular tube. Then, the first laser welding machine 6 set at the end of the slide rail 4 can weld the four connection seams of the thick-walled rectangular tube. During the welding process, the rotating seat set at the end of the laser welding gun neck 602 rotates When the first connecting rod 603 is moved, the first connecting rod 603 fixedly connected on the rotating seat can be rotated to a position corresponding to the thin strip connection seam of the thick-walled rectangular tube. Under the action of the four groups of conveying components 7, the thick-walled rectangular tube after preliminary assembly can be continuously conveyed to the inside of the device. In this process, the nozzle 604 arranged at the end of the first connecting rod 603 can continuously weld the connection seam of the thick-walled rectangular tube until the connection seam of the entire pipe is welded. When the nozzle 604 welds the connection seam of the pipe, the positioning rod 1104 arranged at the corresponding position of the nozzle 604 is opened to contact with the four corners of the pipe under the action of the opening rod 1103. At this time, the four positioning rods 1104 are opened at the same angle, so that the neck 602 of the laser welding gun can always be in the center position inside the pipe, thereby ensuring that the four groups of nozzles 604 always maintain accurate welding of the connection seams at the four corners of the rectangular pipe. The second connecting rod 1106 arranged at the end of the positioning rod 1104 can be rotated and adjusted according to the inclination angle of the positioning rod 1104.Among them, a first motor is provided at the connection between the positioning rod 1104 and the second connecting rod 1106. The first motor can be controlled by the controller to drive the second connecting rod 1106 to rotate. After the second connecting rod 1106 rotates, the connecting shaft 1107 arranged at the end of the second connecting rod 1106 also rotates synchronously to coincide with the connecting seam of the rectangular pipe. Similarly, a second motor is provided at the connection between the second connecting rod 1106 and the connecting shaft 1107. The second motor can be controlled by the controller to drive the connecting shaft 1107 to rotate. At this time, the detection plates 1108 rotatably connected on both sides of the connecting shaft 1107 can fit with the inner walls of the two sides of the rectangular pipe after welding. The outer walls of the two detection plates 1108 are provided with contact sensors. When the outer walls of the detection plates 1108 fit with the inner walls of the rectangular pipe, the signals can be transmitted back to the controller, and then the first motor and the second motor stop, thereby realizing the connection between the two detection plates 1108 and the rectangular pipe. The adaptive adjustment of the inner wall of the rectangular pipe fitting is carried out, and the angle between the two detection plates 1108 is ninety degrees. During the relative movement between the rectangular pipe fitting and the first laser welding machine 6, the detection plate 1108 can detect the angles at the four corners of the rectangular pipe fitting after welding. If the angle between the two rectangular blocks becomes smaller, the rotating gears 1109 fixedly connected to the ends of the two detection plates 1108 squeeze each other. An angle sensor is arranged on the tooth surface of the rotating gear 1109. When the rotating gears 1109 squeeze each other, the sensor can transmit the reading to the controller (Siemens control cabinet), and finally reflect it on the display panel of the device, thereby ensuring the quality of the finished thick-walled rectangular pipe fittings after welding, and avoiding the finished rectangular pipe fittings that are deformed due to the stress of the material itself from entering the market. In the above process, by adjusting the opening angle of the positioning rod 1104, it can be used in conjunction with thick-walled rectangular pipe fittings with square sections of different sizes;,

[0060] In this process, according to the size of the rectangular block used for welding the rectangular pipe fitting, the conveying assembly 7 arranged on the side of the pipe fitting can be deformed according to the actual situation of the pipe fitting, wherein, when the height of the rectangular block is greater than the length of the entire conveying assembly 7, the movable plate 701 and the two rotating plates 702 are in the same plane, then the outer walls of the movable plate 701 and the rotating plate 702 are in contact with the outer walls of the rectangular pipe fitting after the preliminary combination, and under the rolling action of the second roller 708 and the first roller 705 respectively arranged on the movable plate 701 and the rotating plate 702, the pipe fitting is continuously conveyed to the inside of the device for welding, and when the height of the rectangular block is less than the length of the entire conveying assembly 7, the rotating plates 702 arranged at both ends of the movable plate 701 rotate, and at the same time, the clamping plates 703 arranged at the ends of the two rotating plates 702 rotate, and the two clamping plates 703 after rotation can limit the upper and lower edges of the rectangular block respectively, at this time, the clamping plates 703 arranged on the outer wall of the movable plate 701 The two adjusting plates 707 are rotated outwards, and when the second roller 708 arranged at the end of the adjusting plate 707 contacts the outer wall of the rectangular block, the combined rectangular pipe fittings can also be transported by the rotation of the plurality of second rollers 708. It is worth mentioning that in the process of combining the four rectangular blocks into the rectangular pipe fittings, the adjusting base movably connected to the movable plate 701 can adjust the position of the conveying assembly 7 through its existing internal structure, and then adjust the position of the rectangular block clamped by the clamping plate 703, so that the corresponding wall surfaces of the four rectangular blocks are aligned, so that the four rectangular blocks are preliminarily combined into the corresponding rectangular pipe fittings. The four groups of conveying assemblies 7 after the rotating plate 702 is rotated and deformed are also suitable for clamping and conveying the outer wall of the circular pipe fitting, wherein the rotating plate 702 can contact the outer wall of the circular pipe fitting after rotation, so that the plurality of first rollers 705 arranged on the outer wall of the rotating plate 702 convey the circular pipe fittings to the inside of the device after rotation;

[0061] When the rectangular pipe fittings after welding are transported to the inside of the device, the two support rods 803 arranged at the upper end of the base 801 can be lifted upwards under the action of the first electric telescopic rod 805, and the lifted support plate 804 can support the bottom surface of the pipe fittings. At the same time, the base 801 slides toward the end of the bottom plate 1 where the lifting seat 3 is arranged, so that the pipe fittings can move to the inside of the device in accordance with the conveying speed of the conveying assembly 7. Under the action of the base 801 and the support plate 804, the end of the pipe fittings after welding can be prevented from sinking downwards, thereby affecting the welding in the subsequent process.

[0062] When the end of the pipe is transported to the first support assembly 5, the tension rod 502 arranged on the outer wall of the rotating ring 501 rotates and opens outward. After the multiple tension rods 502 are opened outward, for a rectangular pipe with a square cross-section, the ends of the tension rod 502 abut against the four corners of the inner wall of the rectangular pipe. For a circular pipe with a circular cross-section, the contact block 503 arranged at the end of the tension rod 502 can abut against the inner wall of the circular pipe. Then, under the action of the multiple tension rods 502 on the first support assembly 5, the inner wall of the pipe can be supported and fixed, so that the first support assembly 5 and the welded pipe are combined into a whole. When the rotating ring 501 is driven to rotate, the pipe can be driven to rotate synchronously. Then, the user can sleeve the flange and other connectors that need external welding on the outer wall of the pipe after welding. Through the multiple sets of fixing assemblies 12 arranged on the fixing frame 2, the flange and other connectors sleeved on the outside of the pipe can be moved to the end of the pipe after welding.

[0063] When the multiple tensioning rods 502 in the first support assembly 5 are opened to tension and support one end of the pipe after welding, the second support assembly 10 arranged at the other end of the pipe can support the other end of the pipe, wherein the ends of the two lifting rods 1001 connected to the extension plate 9 are brought close to each other, and the second electric telescopic rod 1003 equipped with the auxiliary plate 1004 can be lifted upward to be coaxial with the pipe and the first support assembly 5, and then the telescopic end of the second electric telescopic rod 1003 is extended, and the end of the second electric telescopic rod 1003 equipped with the auxiliary plate 1004 can be extended into the end of the pipe. Fig.10 As shown, when the end of the second electric telescopic rod 1003 extends into the interior of the pipe, the multiple auxiliary plates 1004 can support the interior of the pipe after opening. Then, under the cooperation of the multiple tensioning rods 502 and the multiple auxiliary plates 1004, the two ends of the welded pipe can be supported and fixed. At this time, the multiple positioning rods 1104 arranged outside the first laser welding machine 6 are retracted until their ends do not contact the inner wall of the pipe. Then, by rotating the pipe rotating ring 501, the welded pipe can be driven to rotate synchronously as a whole. It is worth mentioning that, Fig. 9 As shown, when a round pipe or a square pipe is loaded into the device, the second support assembly 10 can be used to provide auxiliary support to the end of the pipe;

[0064] When the first support assembly 5 and the second support assembly 10 respectively support the two ends of the pipe after welding, the support plate 804 located below the pipe is rotated and re-stored in the rectangular groove 802. At this time, the slide groove 807 arranged on the upper surface of the base 801 is docked with the docking groove 806. The sliding seat 808 arranged on the upper surface of the base 801 can slide on the upper surface of the base 801 through the slide groove 807 and the support plate 804. The second laser welding machine 810 is rotatably installed on the sliding seat 808. When the sliding seat 808 is parallel to the base 801, Slide, and then cooperate with the first support component 5 and the second support component 10 to drive the rectangular pipe to rotate. The second laser welding machine 810 can be used to weld the connecting piece set at the end of the rectangular pipe with a square cross-section to the pipe body. When the sliding seat 808 is fixed, adjust the second laser welding machine 810 so that its end contacts the corresponding position of the outer wall of the circular pipe. Then, the first support component 5 and the second support component 10 can be used to weld the circular pipe body to connecting pieces such as flanges. After welding, the pipe can be taken out of the device under the transportation of multiple groups of conveying components 7.
