[0007] As preferred, the swing feeding assembly comprises a swing cylinder and a swing piece body, the swing cylinder is mounted on the side surface of the storage frame; the swing piece body is slidably connected to the storage frame, the piston shaft of the swing cylinder is connected to the swing piece body, and the swing cylinder drives the swing piece body to move up and down relative to the storage frame when the swing cylinder works; the swing piece body is provided with a first pushing part and a second pushing part, and the first pushing part is arranged higher than the second pushing part; a transfer placement part is arranged in the storage frame, and the transfer placement part is arranged between the first pushing part and the second pushing part; the first pushing part, the second pushing part and the transfer placement part are all arranged obliquely; a return channel is arranged in communication with the side surface of the storage frame, and a limiting baffle is fixedly connected to the main frame; the limiting baffle is arranged higher than the feeding channel, and the limiting baffle is arranged at the initial end of the return channel; the distance between the limiting baffle and the chain conveying assembly is adapted to the outer diameter of the short pipe.

[0008] As preferred, the pipeline orientation adjusting device comprises a mounting frame, a rotating cylinder, a rotating support and a limiting protrusion, the mounting frame is provided with an adapter channel between the feeding channel; the end of the pipeline orientation adjusting device away from the adapter channel is provided with a pipeline hole position adjusting device, the pipeline hole position adjusting device comprises a storage channel, the upper end surface of the mounting frame is provided with the adapter channel and the storage channel; the rotating support is rotatably connected to the mounting frame, the bottom of the mounting frame is provided with the rotating cylinder, the rotating shaft of the rotating cylinder is connected to the rotating support; the rotating support is provided with a lifting cylinder, the piston shaft of the lifting cylinder is provided with the limiting protrusion, the limiting protrusion moves up and down relative to the mounting frame when the lifting cylinder works.

[0009] As preferred, the top of the rotating support is provided with a material passing groove, the limiting protrusion penetrates through the material passing groove; in the default state, the opening of the material passing groove is connected to the adapter channel and the storage channel, and the limiting protrusion is in the extended state; the mounting frame is respectively provided with a first infrared sensor and a detection camera, the first infrared sensor and the detection camera are respectively arranged above the material passing groove.

[0010] The short pipes to be welded are placed in the storage frame, and a large number of short pipes are accumulated at the bottom of the storage frame; then the chain conveying assembly and the swing feeding assembly work synchronously to transport the short pipes to the end of the feeding channel. The swing cylinder controls the up-and-down movement of the swing body relative to the storage frame, and the swing body includes a first pushing part and a second pushing part; the second pushing part first transfers the short pipes at the bottom of the storage frame to the intermediate transfer placement part, and then the first pushing part transfers the short pipes on the intermediate transfer placement part to the chain conveying assembly; at this time, the short pipes are arranged between the feeding channel and the chain body; since the first pushing part, the second pushing part and the intermediate transfer placement part are all inclined, the short pipes at the bottom of the storage frame will automatically roll onto the first pushing part, the short pipes on the intermediate transfer placement part will automatically roll onto the second pushing part, and the short pipes on the second pushing part will automatically roll onto the chain body. Then the first motor drives the chain body to rotate, so that the short pipes continuously move to the position of the command plate. When the short pipes are stacked on the feeding channel, the upper short pipes will be stopped by the limiting baffle, and then roll along the inclined surface of the limiting baffle into the return channel, and finally roll into the storage frame along the return channel; by arranging the limiting baffle, the short pipes in the feeding channel can be transported side by side, avoiding the accumulation of short pipes, and the short pipe conveying process is more orderly and reliable. When the short pipe contacts the command plate, the chain body is continuously rotating at this time, so that the short pipe presses the command plate, so that the command plate and the contact switch are in contact with each other, and the contact switch sends a work instruction to the feeding cylinder; the feeding cylinder controls the pushing plate to transport the frontmost short pipe to the switching channel, and then the short pipe enters the pipe along the switching channel into the adjusting device; at this time, the feeding cylinder is in the extended state, so that the switching channel and the feeding channel can be separated, and new short pipes cannot enter the switching channel.

[0011] In the default state, the material passing groove on the rotating support is arranged towards the switching channel, and the limiting protrusion is in the extended state; the outer wall of the short pipe is provided with an annular groove, and the annular groove is arranged towards the same direction when the short pipe and the long pipe are welded; when the short pipe is sent into the automatic welding assembly, the annular groove needs to be arranged towards the tension moving feeding device end. The short pipe is moved to the rotating support along the switching channel, and the limiting protrusion is blocked; at this time, the detection camera takes a picture of the short pipe, and then compares the image with the picture set on the control panel; if the direction of the annular groove on the short pipe is correct, the control panel sends a working instruction to the lifting cylinder, so as to control the limiting protrusion to retract; in this way, the short pipe is gathered to the storage channel along the material passing groove, and then the hole direction of the short pipe is adjusted. When it is detected that the direction of the annular groove on the short pipe is opposite, the control panel sends a working instruction to the rotating cylinder, and the rotating cylinder drives the rotating support to rotate by 180 degrees; since the pipe direction adjusting device is arranged to be inclined relative to the horizontal plane, the short pipe will automatically roll along the material passing groove to the storage channel after rotating by 180 degrees; then the control panel drives the rotating support and the limiting protrusion to reset to the initial state, so as to wait for the new short pipe to be adjusted. The first infrared sensor is arranged to detect whether the short pipe exists in the material passing groove of the rotating support; when the short pipe leaves the material passing groove, the first infrared sensor sends an electrical signal to the control panel, and then the control panel sends an instruction to the feeding cylinder at the end of the feeding channel; the control panel is provided with a time delay, and only when the rotating support and the limiting protrusion reset to the initial state, the feeding cylinder works to transport the new short pipe to the rotating support.

[0012] Preferably, the pipe hole adjusting device comprises a storage channel, a supporting base and a mounting platform, one end of the storage channel is connected with the pipe direction adjusting device, the other end of the storage channel is connected with the supporting base, and the supporting base is arranged below the storage channel; the supporting base is provided with a material rotating assembly; the mounting platform is provided with a tension moving feeding device, and the tension moving feeding device drives the short pipe in the supporting base to be transported to the automatic welding assembly when the tension moving feeding device works; the mounting platform is further provided with a positioning cylinder arranged opposite to the supporting base.

[0014] As preferred, the side surface of the support base is provided with the mounting platform arranged side by side therewith, and the mounting platform is provided with the positioning cylinder; the piston shaft of the positioning cylinder is provided with the positioning die, and the outer shape contour of the positioning die is adapted to the hole position contour on the short pipe; the end of the positioning die is provided with the positioning wheel rotationally connected therewith; the positioning cylinder is arranged towards the short pipe between the second friction roller and the third friction roller; the positioning cylinder is provided with the Hall sensor, and the piston in the positioning cylinder is provided with the magnetic ring; the mounting platform is provided with the tension movable feeding device comprising the transmission belt, the second motor and the sliding plate, the mounting platform is provided with the pulley rotationally connected therewith, and the transmission belt is sleeved and installed on the pulley; the second motor is in transmission connection with one of the pulleys; the mounting platform is provided with the first track extending in the axial direction thereof, and the sliding plate is slidingly installed on the first track and fixedly connected with the transmission belt; the sliding plate is fixedly installed with the telescopic rod, and the telescopic rod is arranged towards the short pipe between the second friction roller and the third friction roller; the telescopic rod is hollowly arranged, and the telescopic rod is provided with the tension rod; the end of the sliding plate is installed with the tension cylinder, and the piston rod of the tension cylinder is connected with the tension rod; the telescopic rod is provided with a plurality of uniformly distributed tension pieces, and the tension pieces are close to or apart from each other when the tension rod is pushed to extend or retract by the tension cylinder.

[0015] When the short pipe is adjusted to face backward, it will first gather in the storage channel, the width of the storage channel and the length of the short pipe are matched with each other, so that the short pipes can be arranged side by side in front and back. The end of the storage channel is provided with a supporting base, and the supporting base is provided with a pipe hole position adjusting device. The short pipe is rotated through the pipe hole position adjusting device, so that the hole position on the short pipe is arranged to face the opening of the long pipe. The second plug is in the extended state by default, and the first plug is in the retracted state; when the short pipe in the storage channel rolls to the second plug, it is just stopped by the second plug; the second infrared sensor between the first plug and the second plug can detect the presence of the short pipe; the second infrared sensor is electrically connected with the control panel, so that the control panel sends a working instruction to the first cylinder and the second cylinder; the first plug is first extended, and then the second plug is retracted once and immediately extended, so that the short pipe between the first plug and the second plug rolls to the material rotating assembly; at this time, the third infrared sensor detects that there is a short pipe between the second friction roller and the third friction roller, so that the third cylinder and the positioning cylinder work synchronously; the third cylinder controls the pressing wheel to position the short pipe from above, and the positioning cylinder controls the positioning die and the positioning wheel to extend; here, the extension position of the positioning die is detected by the Hall sensor and the magnetic ring. When the hole position on the short pipe faces the positioning die, the positioning die can be inserted into the hole position of the short pipe; at this time, the piston of the positioning cylinder is in the maximum extension state, and the magnetic ring on the piston can be close to the Hall sensor setting, so that the Hall sensor setting can send an electrical signal to the control panel, and the control panel sends a motion instruction to the material rotating assembly, so that the material rotating assembly does not work at this time; when the hole position on the short pipe is misaligned with the positioning die, the positioning wheel on the positioning die abuts against the outer wall of the short pipe at this time; because the positioning wheel abuts against the outer wall of the short pipe, the position of the piston in the positioning cylinder does not reach the maximum extension state, but the chamber in the positioning cylinder is still in the inflation state; here, the material rotating assembly needs to determine the position by the Hall sensor and the magnetic ring before rotating; when the positioning cylinder does not completely extend to the maximum stroke, the control panel sends a rotating instruction to the material rotating assembly; when the material rotating assembly works, the driving motor drives the first friction roller to rotate, and the first friction roller, the second friction roller and the third friction roller are all provided with gears, so that the first friction roller, the second friction roller and the third friction roller rotate synchronously; here, the first friction roller is arranged between the second friction roller and the third friction roller, so that the rotation directions of the second friction roller and the third friction roller are opposite; the second friction roller, the third friction roller and the pressing wheel multi-point position the short pipe, so as to drive the short pipe to rotate; when the hole position on the short pipe rotates to align with the positioning die, the end of the positioning die loses the limit, and the positioning die completely extends under the action of the gas pressure, so that the material rotating assembly stops rotating; at this time, the driving motor still has inertia, but the short pipe is stuck by the positioning die, so that the short pipe does not continue to rotate.

[0016] Then the telescopic rod on the tension moving feeding device is axially inserted into the open end of the short pipe to transport the short pipe to the automatic welding assembly; after the telescopic rod is axially inserted into the short pipe, the pressing wheel and the positioning mold are away from the short pipe and reset to the initial state; at this time, the third infrared sensor detects the disappearance of the short pipe on the material rotating assembly, so that the third infrared sensor sends an electrical signal to the control panel, and the control panel makes the first plug-in board retract, so that the new short pipe will appear between the first plug-in board and the second plug-in board; then the above steps are repeated, so that the new short pipe will be continuously transported to the material rotating assembly in turn; when the hole position of the short pipe is oriented, at this time the second motor drives the transmission belt to rotate, which will drive the sliding plate to move; the sliding plate moves to insert the end of the telescopic rod into the open end of the short pipe; by default, the tension cylinder controls the tension rod to be in the extended state, so that the tensioning pieces at the end of the telescopic rod are in close proximity to each other; when the end of the telescopic rod is inside the short pipe, the stroke of the telescopic rod can be adjusted by the rotating state of the second motor, and the telescopic rod will not interfere with the positioning mold; then the tension cylinder controls the tension rod to retract, and the protrusions at the end of the tension rod will push the tensioning pieces apart, so that the telescopic rod can be firmly clamped inside the short pipe; after the tension cylinder retracts, the positioning cylinder and the third cylinder automatically reset, so that the pressing wheel and the positioning mold are away from the short pipe; then the control assembly sends a working instruction to the second motor, so that the telescopic rod with the short pipe moves close to the automatic welding assembly.

[0017] As preferred, the automatic welding assembly comprises a long pipe placing platform, a first pressing member above the long pipe placing platform can move up and down relative to it, the first pressing member and the long pipe placing platform are both metal members; both sides of the long pipe placing platform are provided with short pipe fixing platforms that can move relative to them, both ends of the long pipe placing platform are provided with second rails, and the short pipe fixing platforms are slidingly installed on the second rails; the short pipe fixing platforms are provided with fourth cylinders, the pistons of the fourth cylinders are provided with second pressing members, and the second pressing members and the short pipe fixing platforms are both metal members; a feeding and discharging synchronization assembly is arranged above the long pipe placing platform, and the two short pipe fixing platforms are arranged on the left and right sides of the long pipe placing platform; a discharging frame is arranged on the side of the welding platform, and the discharging frame and the long pipe feeding assembly are arranged on the front and rear sides of the long pipe placing platform.

[0018] When the short pipe is placed on the short pipe fixing platform, the fourth cylinder operates to control the second clamping component to fix the short pipe; at this time, the tensioning cylinder controls the tensioning rod to extend, thereby bringing the tensioning plates closer together; then the second motor operates, controlling the telescopic rod to retract from the short pipe and return to its initial position. Here, the short pipe fixing platform is set on the second track, and the welding platform is equipped with a cylinder that connects to the short pipe fixing platform, thereby driving the short pipe fixing platform to move along the second track. The cylinder is not shown in the attached drawings of the instruction manual. Here, the long pipe is transported from the long pipe loading assembly to the long pipe placement platform via a loading and unloading synchronization component. The welding platform is equipped with a cylinder that drives the first clamping component to move up and down; after the long pipe is placed in position, it is fixed by the first clamping component. Then, the two short pipe fixing platforms are brought close to the long pipe placement platform, thereby assembling the short and long pipes together. Then, the first clamping component is energized, allowing the short and long pipes to be welded together. After welding, the finished product is transported to the unloading frame via the loading and unloading synchronization component. This loading and unloading synchronization component ensures that the loading of the long pipe and the unloading of the finished product are synchronized, resulting in higher overall welding efficiency.

[0019] Compared with the prior art, the present invention has the following beneficial effects: 1. By cooperating with the short pipe continuous feeding device, the pipe orientation adjustment device, and the pipe hole position adjustment device, the position of the short pipe can be continuously adjusted, thereby facilitating the automatic assembly of short pipes and long pipes and subsequent automatic welding; 2. The chain conveyor assembly and the swing feeding assembly can arrange and feed the short pipes, and the limit baffle can block disordered short pipes; 3. By cooperating with the pipe orientation adjustment device and the feeding cylinder, the orientation of the short pipes can be adjusted, so that each short pipe enters the storage channel of the pipe hole position adjustment device in the correct orientation; 4. The pipe hole position adjustment device, through the cooperation of the first and second insert plates, allows the short pipes to enter the material rotation assembly in a sequential manner; 5. The material rotation component works in conjunction with the positioning cylinder. After the orientation of the short pipe hole is adjusted, the material rotation component automatically stops rotating, thus aligning the short pipe hole with the long pipe. 6. The material rotation component and the tensioning and moving feeding device work together to automatically transport the short pipe to the automatic welding component after the hole orientation is adjusted. The tensioning and moving feeding device has a tensioning rod inside, which facilitates the adjustment of the opening and closing state of the telescopic rod. When the telescopic rod needs to be reset, it is easy for the telescopic rod to disengage from the inside of the short pipe. 7. The automatic welding component facilitates the assembly and positioning of the long and short pipes. After welding, the material is unloaded through the loading and unloading synchronization component. The loading and unloading synchronization component has two sets of grippers, which can move the long pipe and the welded product synchronously, resulting in higher overall welding efficiency.

A unloading frame 14 is provided on the side of the welding platform 1, and the unloading frame 14 and the long pipe loading assembly 7 are arranged on the front and rear sides of the long pipe placement platform 51.

[0026] The specific operation process of the embodiment is as follows: the short pipes to be welded are placed in the storage frame 23, at this time a large number of short pipes are stacked at the bottom of the storage frame 23; then the chain conveying assembly 9 and the swing feeding assembly 10 work synchronously to transport the short pipes to the end of the feeding channel 22. The swing cylinder 101 works to control the up-down movement of the swing body 102 relative to the storage frame 23, and the swing body 102 includes a first pushing part 103 and a second pushing part 104; the second pushing part 104 first transfers the short pipes at the bottom of the storage frame 23 to the intermediate transfer placement part 28, and then the first pushing part 103 transfers the short pipes on the intermediate transfer placement part 28 to the chain conveying assembly 9; at this time, the short pipes are arranged between the feeding channel 22 and the chain body 92; since the first pushing part 103, the second pushing part 104 and the intermediate transfer placement part 28 are all inclined, the short pipes at the bottom of the storage frame 23 will automatically roll onto the first pushing part 103, the short pipes on the intermediate transfer placement part 28 will automatically roll onto the second pushing part 104, and the short pipes on the second pushing part 104 will automatically roll onto the chain body 92. Then the first motor 91 works to drive the chain body 92 to rotate, so that the short pipes continuously move to the position where the command plate 27 is located. When the short pipes are stacked on the feeding channel 22, the upper short pipes will be stopped by the limiting baffle 210, and then roll along the inclined surface of the limiting baffle 210 into the return channel 29, and finally roll into the storage frame 23 along the return channel 29; by arranging the limiting baffle 210, the short pipes in the feeding channel 22 can be transported side by side, avoiding the short pipes from being stacked on each other, and the short pipe conveying process is more orderly and reliable. When the short pipes contact the command plate 27, at this time the chain body 92 is continuously rotating, so that the short pipes press the command plate 27, so that the command plate 27 contacts the contact switch 25, and the contact switch 25 sends a work instruction to the feeding cylinder 24; the feeding cylinder 24 controls the pushing plate 26 to transport the frontmost short pipe to the transfer channel 11, and then the short pipe enters the pipe orientation adjusting device 3 along the transfer channel 11; at this time, the feeding cylinder 24 is in the extended state, so as to separate the transfer channel 11 and the feeding channel 22, avoiding new short pipes from entering the transfer channel 11.

[0027] In the default state, the overpassing groove 36 on the rotating support 33 is set towards the switching channel 11, and the limiting protrusion 34 is in the extended state; the outer wall of the short pipe is provided with an annular groove, and the annular groove is set towards the direction that needs to be kept consistent when the short pipe and the long pipe are welded; when the short pipe is sent into the automatic welding assembly 5, the annular groove needs to be set towards the side of the tension moving feeding device 6. When the short pipe moves along the switching channel 11 to the rotating support 33, the limiting protrusion 34 will be blocked; at this time, the detection camera 38 will take a picture of the short pipe, and then compare the image with the picture set on the control panel; if the direction of the annular groove on the short pipe is correct, the control panel will send a working instruction to the lifting cylinder 35, so as to control the limiting protrusion 34 to retract; in this way, the short pipe will gather along the overpassing groove 36 to the storage channel 41, and then the hole direction of the short pipe is adjusted. When it is detected that the direction of the annular groove on the short pipe is opposite, the control panel will send a working instruction to the rotating cylinder 32, and the rotating cylinder 32 drives the rotating support 33 to rotate by 180 degrees; since the pipe direction adjusting equipment 3 is set to be inclined relative to the horizontal plane, after the short pipe rotates by 180 degrees, it will automatically roll along the overpassing groove 36 to the storage channel 41; then the control panel drives the rotating support 33 and the limiting protrusion 34 to reset to the initial state, so as to wait for the new short pipe to be adjusted. The first infrared sensor 37 is set here to detect whether there is a short pipe in the overpassing groove 36 of the rotating support 33; when the short pipe leaves the overpassing groove 36, the first infrared sensor 37 sends an electrical signal to the control panel, and then the control panel sends an instruction to the feeding cylinder 24 at the end of the feeding channel 22; the control panel is provided with a time delay here, and only when the rotating support 33 and the limiting protrusion 34 reset to the initial state, the feeding cylinder 24 will work to send the new short pipe to the rotating support 33.

[0028] When the short pipe is adjusted to face backward, it will first gather in the storage channel 41, the width of the storage channel 41 and the length of the short pipe are matched with each other, so that the short pipes can be arranged side by side in front and back. The end of the storage channel 41 is provided with a supporting base 42, and the supporting base 42 is provided with a pipe hole adjusting device 4. The short pipe is rotated through the pipe hole adjusting device 4, so that the hole position of the short pipe is arranged to face the opening of the long pipe. By default, the second plug plate 48 is in the extended state, and the first plug plate 47 is in the retracted state. When the short pipe in the storage channel 41 rolls to the second plug plate 48, it is just stopped by the second plug plate 48. The second infrared sensor 411 is arranged between the first plug plate 47 and the second plug plate 48, so that the second infrared sensor 411 can detect the presence of the short pipe. The second infrared sensor 411 is electrically connected with the control panel, so that the control panel sends a working instruction to the first cylinder 44 and the second cylinder 45. The first plug plate 47 is first extended, and then the second plug plate 48 is retracted once and immediately extended, so that the short pipe between the first plug plate 47 and the second plug plate 48 rolls to the material rotating assembly 12. At this time, the third infrared sensor 412 detects the presence of the short pipe between the second friction roller 123 and the third friction roller 124, so that the third cylinder 46 and the positioning cylinder 13 work synchronously. The third cylinder 46 controls the pressing wheel 410 to position the short pipe from above, and the positioning cylinder 13 controls the positioning mold 131 and the positioning wheel 132 to extend. Here, the extension position of the positioning mold 131 is detected by the Hall sensor 133 and the magnetic ring.When the hole position of the short pipe is oriented towards the positioning mold 131, the positioning mold 131 can be inserted into the hole position of the short pipe; at this time, the piston of the positioning cylinder 13 is in the maximum extension state, and the magnetic ring on the piston can be close to the Hall sensor 133 setting, and the Hall sensor 133 setting can send an electrical signal to the control panel, and the control panel sends an action instruction to the material rotating assembly 12, at this time the material rotating assembly 12 will not work; when the hole position of the short pipe is misaligned with the positioning mold 131, at this time the positioning wheel 132 on the positioning mold 131 abuts against the outer wall of the short pipe; because the positioning wheel 132 abuts against the outer wall of the short pipe, so that the position of the piston in the positioning cylinder 13 does not reach the maximum extension state, but the chamber in the positioning cylinder 13 is still in the inflation state; here the material rotating assembly 12 needs to be position judged by the Hall sensor 133 and the magnetic ring before rotating; when the positioning cylinder 13 is not completely extended to the maximum stroke, the control panel will send a rotating instruction to the material rotating assembly 12; when the material rotating assembly 12 works, the driving motor 121 drives the first friction roller 122 to rotate, the first friction roller 122, the second friction roller 123 and the third friction roller 124 are all installed with gears 125, so that the first friction roller 122, the second friction roller 123 and the third friction roller 124 will rotate synchronously; here the first friction roller 122 is arranged between the second friction roller 123 and the third friction roller 124, so that the rotating directions of the second friction roller 123 and the third friction roller 124 are opposite; the second friction roller 123, the third friction roller 124 and the pressing wheel 410 multi-point position the short pipe, so as to drive the short pipe to rotate; when the hole position of the short pipe rotates to align with the positioning mold 131, the end of the positioning mold 131 loses the limit, the positioning mold 131 completely extends under the action of the gas pressure, the Hall sensor 133 can generate an electrical signal, and the control panel will make the material rotating assembly 12 stop rotating; at this time the driving motor 121 still has inertia, but the short pipe is clamped by the positioning mold 131, at this time the short pipe will not continue to rotate.

[0029] Then the telescopic rod 66 on the tensioning moving feeding device 6 is axially inserted into the open end of the short pipe, and the short pipe is transported to the automatic welding assembly 5; after the telescopic rod 66 is axially inserted into the short pipe, the pressing wheel 410 and the positioning mold 131 are away from the short pipe and reset to the initial state; at this time, the third infrared sensor 412 detects the disappearance of the short pipe on the material rotating assembly 12, so that the third infrared sensor 412 sends an electrical signal to the control panel, and the control panel makes the first plug-in board 47 contract, so that the new short pipe will appear between the first plug-in board 47 and the second plug-in board 48; then the above steps are repeated, so that the new short pipe will be continuously transported to the material rotating assembly 12 in turn; when the hole position of the short pipe is oriented, at this time the second motor 62 drives the transmission belt 61 to rotate, and the transmission belt 61 drives the sliding plate 63 to move; when the sliding plate 63 moves, the end of the telescopic rod 66 is inserted into the open end of the short pipe; by default, the tensioning cylinder 68 controls the tensioning rod 67 to be in the extended state, so that the tensioning pieces 69 at the end of the telescopic rod 66 are in the state of approaching each other; when the end of the telescopic rod 66 is inside the short pipe, the stroke of the telescopic rod 66 can be adjusted by the rotating state of the second motor 62, and the telescopic rod 66 will not interfere with the positioning mold 131; then the tensioning cylinder 68 controls the tensioning rod 67 to contract, and the protrusions at the end of the tensioning rod 67 will push the tensioning pieces 69 to open to each other, so that the telescopic rod 66 can be firmly clamped inside the short pipe; after the tensioning cylinder 68 contracts, the positioning cylinder 13 and the third cylinder 46 are automatically reset, so that the pressing wheel 410 and the positioning mold 131 are away from the short pipe; then the control assembly sends a working instruction to the second motor 62, so that the telescopic rod 66 moves with the short pipe to the automatic welding assembly 5.

[0030] When the short pipe is placed on the short pipe fixing platform 53, the fourth cylinder 55 works to control the second pressing member 56 to fix the short pipe; at this time, the tensioning cylinder 68 controls the tensioning rod 67 to extend, so that the tensioning pieces 69 are close to each other; then the second motor 62 works to control the telescopic rod 66 to withdraw from the short pipe and reset to the initial position. Here, the short pipe fixing platform 53 is arranged on the second track 54, and the welding platform 1 is provided with a cylinder connected with the short pipe fixing platform 53, so as to drive the short pipe fixing platform 53 to move along the second track 54, which is not shown in the drawings. Here, the long pipe is transported to the long pipe placing platform 51 from the long pipe feeding assembly 7 through the feeding and discharging synchronization assembly 8; here, the welding platform 1 is provided with a cylinder driving the first pressing member 52 to move up and down, and the long pipe is fixed by the first pressing member 52 after being placed in position; then the two short pipe fixing platforms 53 are close to the long pipe placing platform 51, so that the short pipe and the long pipe are assembled together; then the first pressing member 52 is powered on, so that the short pipe and the long pipe can be welded with each other; after the welding is completed, the finished product is transported to the discharging frame 14 through the feeding and discharging synchronization assembly 8; here, the feeding and discharging synchronization assembly 8 is arranged, so that the long pipe feeding and the finished product discharging are carried out synchronously, and the overall welding efficiency is higher.
