[0016] (3) Beneficial effects

[0017] The present invention provides a sports equipment processing and welding device. It has the following beneficial effects:

[0018] (1) The welding device starts the second motor through the driving device when in use, and its output end drives the driving gear to rotate. The driving gear on one side of the base transmits power through the connected square rod, and the driving gear on the other side of the base is slidably connected to the square rod through the square hole, thereby realizing the synchronous rotation of the driving gears on both sides, and then driving the fixing device to operate, thereby achieving the clamping and positioning of the steel pipe.

[0019] (2) The welding device, through the fixing device, when in use, the second motor drives the active gear to rotate, and the active gear engages the transmission gear ring to rotate; when the transmission gear ring rotates, the arc-shaped hole on its side wall drives the slider to slide along the track in the groove, and the slider links the clamping plate to move radially in the limiting opening of the limiting ring, so that the clamping plate can move centripetally or centrifugally to achieve the clamping or loosening of the steel pipe. After the steel pipe is fixed by the clamping plate, when it is necessary to weld other parts of the steel pipe, the transmission gear ring is rotated clockwise, and the clamping plate has fixed the steel pipe, thereby driving the limiting ring to overcome the limiting device and rotate, which in turn drives the steel pipe to rotate at a uniform speed, so that the laser welding device can weld other parts of the steel pipe uniformly.

[0020] (3) The welding device uses a clamping device. When the clamping plate moves radially along the limit opening under the drive of the transmission gear ring, the first hinged rod hinged at the end of the clamping plate swings synchronously with the clamping plate, driving the elastic clamping pad to approach the surface of the steel pipe; after the elastic clamping pad contacts the steel pipe, it conforms to the pipe wall through its own deformation. As the clamping plate moves further, the first hinged rod rotates around the hinge point, causing the elastic clamping pad to press the steel pipe at an adaptive angle, completing flexible clamping and reducing the local stress concentration problem of traditional rigid clamps.

[0021] (IV) The welding device, through the pressing device and the docking device, is used when the driving device is started to drive the fixing device on the bracket to operate, and the multiple clamps perform centrifugal motion in the limit opening. The second hinged rod rotates around the clamps, and the limit shaft slides in the slide groove of the side plate, pushing the lower pressing plate to move in the direction close to the steel pipe. When the lower pressing plate pushes the docking device to fix the steel pipe, it pushes the U-shaped frame to overcome the resistance of the abutment device to drive the roller to perform centripetal motion, so that the multiple rollers fit the surface of the steel pipe, and the rollers are elastic, forming an elastic fixation. Start the third motor to push the steel pipe, and the anti-deviation device is used to limit the deviation of the steel pipe during the pushing process, so that the two steel pipes are docked more accurately. Subsequently, the laser welding device on the top wall of the base is driven to slide to the welding position for subsequent fixed welding; after the welding is completed, start the third motor to convey and remove the welded steel pipe, which solves the problem of inaccurate docking of the two steel pipes and easy deviation during the welding process.

[0022] (V) The welding device, through the anti-deviation device, drives the anti-deviation device to move centripetally when the U-shaped frame moves centripetally. Multiple anti-deviation rollers first contact and abut against the steel pipe, forming an elastic fixation to prevent the steel pipe from being damaged or stuck in position due to mechanical hard contact. When the U-shaped frame is moved, the anti-deviation roller is forced to move backward, and the torque spring is deformed by the force until the rotating roller abuts against the side wall of the steel pipe. The connecting rod abuts against the side wall of the first limit block, so that the anti-deviation roller will not be forced to move backward during the subsequent pushing process of the steel pipe, forming a rigid fixation. The front and rear sides around the side wall of the steel pipe are respectively abutted against the anti-deviation roller and the rotating roller, limiting the displacement of the steel pipe during the pushing process, making the docking position of the two steel pipes more stable.

The side wall of the side plate 53 is provided with a slide groove 54, and the limit shaft 52 is slidably connected to the inner wall of the slide groove 54. The end of the second hinged rod 51 away from the splint 43 is hingedly connected to the lower pressure plate 55; the docking device 60 includes a fixed frame 61, the inner wall of the fixed frame 61 is fixedly connected to the side wall of the limit ring 41, and the inner wall of the fixed frame 61 is symmetrically slidably connected to the abutment device 62, the side wall of the abutment device 62 is fixedly connected to the U-shaped frame 63, the inner wall of the U-shaped frame 63 is fixedly connected to the roller 64, the side wall of the U-shaped frame 63 is rotatably connected to the anti-deflection device 65, and the side wall of the U-shaped frame 63 is fixedly connected to the third motor 66, and the output end of the third motor 66 is fixedly connected to the side wall of the roller 64.

[0034] When in use, first place the two welding steel pipes in the limiting rings 41 on both sides of the base 10 respectively, the driving device 30 is started, driving the fixing device 40 on the bracket 11 to operate, the six clamping plates 43 slide in the limiting opening 42 in the direction away from the steel pipe, the second hinge rod 51 rotates around the clamping plate 43, and the limiting shaft 52 slides in the slide groove 54 of the side plate 53, pushing the lower pressure plate 55 to move in the direction close to the steel pipe, pushing the U-shaped frame 63 to overcome the resistance of the abutment device 62 and drive the roller 64 to do centripetal movement, so that the six rollers 64 fit the surface of the steel pipe, and the roller 64 is elastic to form an elastic fixation, start the third motor 66, and push the steel pipe. The anti-deflection device 65 is used to make it difficult for the steel pipe to deviate during the pushing process, making the two steel pipes more accurately connected. Subsequently, the laser welding device 20 on the top wall of the base 10 slides to the welding position under drive for subsequent fixed welding; it solves the problem that the two steel pipes are difficult to achieve accurate docking and it is difficult to deviate during the welding process.

[0035] The abutment device 62 includes an insertion rod 621, an end of the insertion rod 621 close to the fixing frame 61 passes through the side wall of the fixing frame 61 and is fixedly connected to a first mounting plate 622, a side wall of the first mounting plate 622 is fixedly connected to a first abutment block 623, a side wall of the U-shaped frame 63 is fixedly connected to a second mounting plate 624, a side wall of the second mounting plate 624 is fixedly connected to a second abutment block 625, a side wall of the first mounting plate 622 is fixedly connected to a second return spring 626, an end of the second return spring 626 away from the first mounting plate 622 is fixedly connected to the inner wall of the fixing frame 61, wherein the top wall of the first abutment block 623 is inclined, and the first The bottom wall of the abutment block 623 is perpendicular to the sliding direction of the U-shaped frame 63, and the top wall of the second abutment block 625 is perpendicular to the sliding direction of the U-shaped frame 63. The bottom wall of the second abutment block 625 is tilted. When the lower pressing plate 55 makes a centripetal movement and pushes the U-shaped frame 63 to overcome the resistance of the abutment device 62 and make a centripetal movement, the second mounting plate 624 and the second abutment block 625 make a centripetal movement. The tilted top wall of the first abutment block 623 abuts against the tilted bottom wall of the second abutment block 625. The second abutment block 625 pushes the first abutment block 623 to move away from the second abutment block 625, and the second return spring 626 is compressed. Until the roller 64 fits the surface of the steel pipe, the U-shaped frame 63 stops moving, the second return spring 626 releases the elastic potential energy, and moves in the opposite direction through the first mounting plate 622 and the first abutment block 623, so that the first abutment block 623 abuts against the second abutment block 625. When the roller 64 fits the surface of the steel pipe, the third motor 66 is started to rotate the roller 64 to push the steel pipe. The same method is used to push the steel pipe on the other side and complete the subsequent docking. After the docking is completed, the drive device 30 is started to make the splint 43 move centripetally to fix the steel pipe. The second hinged rod 51 is flipped over to drive the lower pressure plate 55 to do centrifugal movement. As a result, the U-shaped frame 63 is no longer subjected to the pressure of the lower pressure plate 55, and the roller 64 is subjected to the resistance of the steel pipe. When it is easy to move backward, the bottom wall of the first abutment block 623 abuts against the top wall of the second abutment block 625, and the bottom wall of the first abutment block 623 and the top wall of the second abutment block 625 are both perpendicular to the sliding direction of the U-shaped frame 63. The roller 64 can only move backward a little, and the roller 64 is elastic, so that when the splint 43 fixes the steel pipe, the roller 64 can always be in contact with the side wall of the steel pipe, and the anti-deflection device 65 forms a limit for the steel pipe, making it difficult for the steel pipe to shake and deviate during the fixation process by the fixing device 40.

[0036] The anti-deflection device 65 includes a rotating shaft 651, which is rotatably connected to a connecting rod 652, and an end of the connecting rod 652 away from the rotating shaft 651 is rotatably connected to an anti-deflection roller 653, and the side wall of the rotating shaft 651 is fixedly connected to a torque spring 654, and the side wall of the torque spring 654 is fixedly connected to the side wall of the U-shaped frame 63, and the side wall of the U-shaped frame 63 is fixedly connected to a first limit block 655 and a second limit block 656; when the U-shaped frame 63 makes a centripetal motion, the U-shaped frame 63 can drive the anti-deflection device 65 to make a centripetal motion, and the six anti-deflection rollers 653 first contact and counteract the steel pipe, forming an elastic fixation, reducing At the beginning, the surface of the steel pipe is damaged or the positioning is stuck due to mechanical hard contact. The U-shaped frame 63 is moved, the anti-deflection roller 653 is forced to move backward, and the torque spring 654 is deformed under the force until the rotating roller 64 is against the side wall of the steel pipe. The connecting rod 652 is against the side wall of the first limit block 655, so that the anti-deflection roller 653 will not be forced to move backward during the subsequent pushing process of the steel pipe, forming a rigid fixation. The front and rear sides around the side wall of the steel pipe are respectively against the anti-deflection roller 653 and the rotating roller 64, making it difficult for the steel pipe to deviate during the pushing process, making the docking position of the two steel pipes more stable.

[0037] The driving device 30 includes a second motor 31, the side wall of the second motor 31 is fixedly connected to the side wall of the bracket 11, and the output end of the second motor 31 is fixedly connected to the driving gear 32, the driving gear 32 on one side of the base 10 is fixedly connected to the square rod 33, and the driving gear 32 on the other side is provided with a square hole 34, and the side wall of the square rod 33 is slidably fitted with the inner wall of the square hole 34; when in use, the second motor 31 is started, and its output end drives the driving gear 32 to rotate, and the driving gear 32 on one side of the base 10 transmits power through the connected square rod 33, and the driving gear 32 on the other side of the base 10 is slidably connected to the square rod 33 through the square hole 34, thereby realizing the synchronous rotation of the driving gears 32 on both sides, and then driving the fixing device 40 to operate, thereby realizing the clamping and positioning of the steel pipe.

[0038] The inner wall of the bracket 11 is rotatably connected with a transmission gear ring 44, which meshes with the active gear 32. The side wall of the transmission gear ring 44 is provided with an arc-shaped hole 45, and the inner wall of the arc-shaped hole 45 is slidably connected with a slider 46. The side wall of the slider 46 is fixedly connected to the side wall of the clamping plate 43; the second motor 31 drives the active gear 32 to rotate, and the active gear 32 meshes with the transmission gear ring 44 to rotate it; when the transmission gear ring 44 rotates, the arc-shaped hole 45 on its side wall drives the slider 46 to slide along the track in the groove, and the slider 46 links the clamping plate 43 to move radially in the limiting opening 42 of the limiting ring 41, first moving the clamping plate 43 in the direction away from the steel pipe, driving the pressing device 50 to push the roller 64 and the anti-deflection roller 653 in the docking device 60 to push the steel pipe fixedly, reversely rotating the active gear 32, and the transmission gear ring 44 rotates in the opposite direction, so that the clamping plate 43 The plate 43 moves centripetally, and the splint 43 also moves centripetally to clamp the steel pipe. The roller 64 and the anti-deviation roller 653 always abut against the side wall of the steel pipe, making it difficult for the steel pipe to deviate during the fixing process. The six splints 43 are linked with the same transmission gear ring 44 through their respective sliders 46 to ensure that all splints 43 open and close synchronously, reducing the skewness of the steel pipe or local stress concentration caused by asynchronous clamping. After fixing the steel pipe, start the laser welding device 20 to weld the steel pipe. When it is necessary to weld other parts of the steel pipe, continue to reverse the driving gear 32, and the transmission gear ring 44 rotates in the opposite direction. The splint 43 has fixed the steel pipe, so that the splint 43 will drive the limit ring 41 to overcome the limit device 48 and rotate, and correspondingly drive the steel pipe to rotate at a uniform speed, so that the laser welding device 20 can weld other positions of the steel pipe evenly.

[0039] The end of the splint 43 away from the limiting ring 41 is hinged with a clamping device 47, and the clamping device 47 includes a first hinged rod 471, one end of the first hinged rod 471 is hinged to the side wall of the splint 43, and the other end is hinged with an elastic clamping pad 472; when the splint 43 moves radially along the limiting opening 42 driven by the transmission gear ring 44, the first hinged rod 471 hinged at the end of the splint 43 swings synchronously with the splint 43, driving the elastic clamping pad 472 to approach the surface of the steel pipe; after the elastic clamping pad 472 contacts the steel pipe, it conforms to the pipe wall through its own deformation. As the splint 43 moves further, the first hinged rod 471 rotates around the hinge point, so that the elastic clamping pad 472 presses the steel pipe at an adaptive angle to complete flexible clamping; it can reduce the local stress concentration problem of traditional rigid clamps.

[0040] The side wall of the limiting ring 41 is fixedly connected to the limiting device 48, which includes a first clamping block 481. The side wall of the first clamping block 481 is fixedly connected to the side wall of the limiting ring 41. The inner wall of the bracket 11 is fixedly connected to a fixing ring 482. The side wall of the fixing ring 482 is fixedly connected to a first return spring 483. The end of the first return spring 483 away from the fixing ring 482 is fixedly connected to a mounting ring 484. The side wall of one side of the mounting ring 484 is fixedly connected to a second clamping block 485, and the side wall of the other side is fixedly connected to a slide rod 486. The side wall of the fixing ring 482 is provided with a sliding hole 48 7; The side wall of the first clamping block 481 close to the counterclockwise direction is perpendicular to the rotation direction of the transmission gear ring 44, and the side wall of the second clamping block 485 close to the clockwise direction is perpendicular to the rotation direction of the transmission gear ring 44; the first clamping block 481 is inclined near the side wall in the clockwise direction, and the second clamping block 485 is inclined near the side wall in the counterclockwise direction. Therefore, when the transmission gear ring 44 rotates clockwise, the vertical side wall of the second clamping block 485 will contact the inclined side wall of the first clamping block 481. Due to the guiding effect of the inclined surface, the mounting ring 484 can compress the first return spring 483 to make the clamping block 481 The connecting blocks are separated, allowing the limiting ring 41 to rotate clockwise; but when rotating counterclockwise, the vertical side wall of the first clamping block 481 is pressed against the inclined side wall of the second clamping block 485, and the inclined surface cannot push the spring to compress, thereby locking the limiting ring 41 to rotate counterclockwise and realizing one-way rotation; when the transmission gear ring 44 rotates counterclockwise, it will drive the splint 43 to do centrifugal movement through the arc hole 45 and the slider 46, thereby pushing the docking device 60 through the pressing device 50 to fixedly transmit and dock the steel pipe, and the limiting ring 41 is difficult to shake under the limit of the limiting device 48, making it difficult for the limiting ring 41 to affect the steel pipe. Transmission and docking of pipes; when the transmission gear ring 44 rotates clockwise, it will drive the splint 43 to move centripetally through the arc hole 45 and the slider 46, so that the chuck device 47 fixes the steel pipe, and continues to rotate the transmission gear ring 44 clockwise. The splint 43 has fixed the steel pipe, so that the splint 43 will drive the limit ring 41 to overcome the limit device 48 and rotate, and correspondingly drive the steel pipe to rotate at a uniform speed, and protect the chuck device 47 to reduce damage between the chuck device 47 and the steel pipe due to excessive resistance, so that the laser welding device 20 can weld other positions of the steel pipe evenly.

The mounting bracket 22 cooperates with the thread of the screw 212 through the thread groove 215 and makes a linear motion along the support plate 211. At the same time, the limiting rod 214 passes through the limiting hole 216 of the mounting bracket 22 to provide guidance for the mounting bracket 22, ensuring that it moves smoothly along the axis of the screw 212 until the laser welding gun 24 reaches the specified position of the steel pipe butt weld. Therefore, the sliding device 21 is used to drive the laser welding gun 24 to align with the butt joint of the two steel pipes for welding.

[0043] Working principle:

[0044] When in use, the welding device consists of a base 10, a laser welding device 20, a driving device 30, a fixing device 40, a pressing device 50 and a docking device 60, wherein the laser welding device 20 is used to weld steel pipes, the driving device 30 is used to first drive the fixing device 40 to move the pressing device 50, and the pressing device 50 then enables the docking device 60 to roll and fix the steel pipe, and starts the docking device 60 to transport and dock the two steel pipes. After the docking is completed, the driving device 30 is started again to drive the fixing device 40 to fix the steel pipe, and the two steel pipes can be synchronously flipped during the fixing process, so that the laser welding device 20 can quickly weld other positions of the steel pipe.

[0045] Among them, the laser welding device 20 includes a sliding device 21, a mounting frame 22, a cylinder 23, and a laser welding gun 24. When in use, the sliding device 21 drives the mounting frame 22 to slide along the top wall of the base 10, and moves the laser welding gun 24 to the top of the steel pipe joint; then the cylinder 23 is started, and its output end pushes the laser welding gun 24 vertically close to the surface of the steel pipe, and at the same time the laser beam is focused for welding to complete the continuous welding operation.

[0046] The sliding device 21 includes a support plate 211, a screw 212, a first motor 213, and a limiting rod 214; when in use, the first motor 213 is started to drive the screw 212 to rotate, and the mounting frame 22 cooperates with the thread of the screw 212 through the thread groove 215 to make a linear motion along the support plate 211; at the same time, the limiting rod 214 passes through the limiting hole 216 of the mounting frame 22 to provide a guide for the mounting frame 22 to ensure that it moves smoothly along the axis of the screw 212 until the laser welding gun 24 reaches the specified position of the steel pipe butt weld. Therefore, the sliding device 21 is used to drive the laser welding gun 24 to align with the butt joint of the two steel pipes for welding.

[0047] The driving device 30 includes a second motor 31, a driving gear 32, and a square rod 33. When in use, the second motor 31 is started, and its output end drives the driving gear 32 to rotate. The driving gear 32 on one side of the base 10 transmits power through the connected square rod 33, and the driving gear 32 on the other side of the base 10 is slidably connected to the square rod 33 through the square hole 34, thereby realizing the synchronous rotation of the driving gears 32 on both sides, and then driving the fixing device 40 to operate, thereby achieving the clamping and positioning of the steel pipe.

[0048] The fixing device 40 includes a limiting ring 41, a splint 43, a transmission gear ring 44, and a slider 46; when in use, the second motor 31 drives the active gear 32 to rotate, and the active gear 32 engages the transmission gear ring 44 to rotate it; when the transmission gear ring 44 rotates, the arc-shaped hole 45 on its side wall drives the slider 46 to slide along the track in the groove, and the slider 46 links the splint 43 to move radially in the limiting opening 42 of the limiting ring 41, so that the splint 43 can perform centripetal or centrifugal movement, so that the splint 43 can clamp or loosen the steel pipe. After the steel pipe is fixed by the splint 43, when it is necessary to weld other parts of the steel pipe, the transmission gear ring 44 is rotated clockwise, and the splint 43 has fixed the steel pipe, so that the splint 43 will drive the limiting ring 41 to overcome the limiting device 48 to rotate, and correspondingly drive the steel pipe to rotate at a uniform speed, so that the laser welding device 20 can weld other positions of the steel pipe evenly.

[0049] The clamping device 47 includes a first hinged rod 471 and an elastic clamping pad 472; one end of the first hinged rod 471 is hinged to the side wall of the clamping plate 43, and the other end is hinged to the elastic clamping pad 472; when the clamping plate 43 moves radially along the limit opening 42 under the drive of the transmission gear ring 44, the first hinged rod 471 hinged at the end of the clamping plate 43 swings synchronously with the clamping plate 43, driving the elastic clamping pad 472 to approach the surface of the steel pipe; after the elastic clamping pad 472 contacts the steel pipe, it conforms to the pipe wall through its own deformation. As the clamping plate 43 moves further, the first hinged rod 471 rotates around the hinge point, so that the elastic clamping pad 472 presses the steel pipe at an adaptive angle to complete flexible clamping; it can reduce the local stress concentration problem of traditional rigid clamps.

[0050] The limiting device 48 includes a first clamping block 481, a fixing ring 482, a first return spring 483, a mounting ring 484, a second clamping block 485, and a slide rod 486; the side wall of the first clamping block 481 close to the counterclockwise direction is perpendicular to the rotation direction of the transmission gear ring 44, and the side wall of the second clamping block 485 close to the clockwise direction is perpendicular to the rotation direction of the transmission gear ring 44; the side wall of the first clamping block 481 close to the clockwise direction is inclined, and the side wall of the second clamping block 485 close to the counterclockwise direction is inclined. The side wall in the clockwise direction is inclined. Therefore, when the transmission gear ring 44 rotates clockwise, the vertical side wall of the second clamping block 485 will contact the inclined side wall of the first clamping block 481. Due to the guiding effect of the inclined surface, the mounting ring 484 can compress the first return spring 483 to separate the clamping blocks, allowing the limit ring 41 to rotate clockwise; but when rotating counterclockwise, the vertical side wall of the first clamping block 481 is pressed against the inclined side wall of the second clamping block 485, and the inclined surface cannot push the spring to compress, thereby The locking limit ring 41 rotates counterclockwise to achieve one-way rotation; when the transmission gear ring 44 rotates counterclockwise, it will drive the clamping plate 43 to do centrifugal motion through the arc hole 45 and the slider 46, so that the steel pipe is fixedly conveyed and docked by the pressing device 50. The limit ring 41 is difficult to shake under the limit of the limit device 48, so that the limit ring 41 is difficult to affect the conveying and docking of the steel pipe; when the transmission gear ring 44 rotates clockwise, it will drive the clamping plate 43 to do centrifugal motion through the arc hole 45 and the slider 46, so that the pressing device 50 can push the docking device 60 to fix the steel pipe. Drive the splint 43 to move centripetally, so that the chuck device 47 fixes the steel pipe, and continue to rotate the transmission gear ring 44 clockwise. The splint 43 has fixed the steel pipe, so that the splint 43 will drive the limit ring 41 to overcome the limit device 48 and rotate, which in turn drives the steel pipe to rotate at a uniform speed and protects the chuck device 47 to reduce damage between the chuck device 47 and the steel pipe due to excessive resistance, so that the laser welding device 20 can weld other positions of the steel pipe evenly.

[0051] The pressing device 50 includes a second hinged rod 51, a limiting shaft 52, a side plate 53, and a lower pressing plate 55; when in use, first place the two welded steel pipes in the limiting rings 41 on both sides of the base 10 respectively, start the driving device 30, and drive the fixing device 40 on the bracket 11 to operate, and the six splints 43 perform centrifugal motion in the limiting mouth 42, and the second hinged rod 51 rotates around the splint 43, and the limiting shaft 52 slides in the slide groove 54 of the side plate 53, pushing the lower pressing plate 55 to move in the direction close to the steel pipe, and the lower pressing plate 55 pushes the docking device 60 to fix the steel pipe, which is convenient for subsequent transmission and docking.

[0052] The docking device 60 includes a fixing frame 61, an abutting device 62, a U-shaped frame 63, a rotating roller 64, an anti-deviation device 65 and a third motor 66. When the lower pressure plate 55 pushes the docking device 60 to fix the steel pipe, the lower pressure plate 55 pushes the U-shaped frame 63 to overcome the resistance of the abutting device 62 and drive the rotating roller 64 to move centripetally, so that the six rotating rollers 64 fit the surface of the steel pipe, and the rotating roller 64 is elastic, forming an elastic fixation, and the third motor 66 is started to push the steel pipe. The anti-deviation device 65 is used to make it difficult for the steel pipe to deviate during the pushing process, so that the two steel pipes are docked more accurately. Subsequently, the laser welding device 20 on the top wall of the base 10 is driven to slide to the welding position for subsequent fixed welding; after welding is completed, the third motor 66 can be started to transport and take out the welded steel pipe, which solves the problem that the two steel pipes are difficult to dock accurately, and it is difficult to deviate during the welding process.

[0053] The abutment device 62 includes an insert rod 621, a first mounting plate 622, a first abutment block 623, a second mounting plate 624, a second abutment block 625, and a second return spring 626; when the lower pressing plate 55 makes a centripetal movement and pushes the U-shaped frame 63 to overcome the resistance of the abutment device 62 and make a centripetal movement, the second mounting plate 624 and the second abutment block 625 make a centripetal movement, the inclined top wall of the first abutment block 623 and the inclined bottom wall of the second abutment block 625 abut against each other, and the first abutment block 623 and the second abutment block 625 are in abutment against each other. The second abutment block 625 pushes the first abutment block 623 to move away from the second abutment block 625, and the second return spring 626 is compressed until the roller 64 contacts the surface of the steel pipe. The U-shaped frame 63 stops moving, and the second return spring 626 releases its elastic potential energy and moves in the opposite direction through the first mounting plate 622 and the first abutment block 623, so that the first abutment block 623 contacts the second abutment block 625. When the roller 64 contacts the surface of the steel pipe, the third motor 66 is started and the roller 64 contacts the surface of the steel pipe. The movable roller 64 pushes the steel pipe, and the same method is used to push the steel pipe on the other side, and completes the subsequent docking. After the docking is completed, the driving device 30 is started, causing the splint 43 to move centripetally to fix the steel pipe, and the second hinged rod 51 is flipped, driving the lower pressure plate 55 to move centrifugally, so that the U-shaped frame 63 is no longer subjected to the pressure of the lower pressure plate 55, and the roller 64 is subjected to the resistance of the steel pipe. When it is easy to move backward, the bottom wall of the first abutment block 623 abuts against the top wall of the second abutment block 625, and the bottom wall of the first abutment block 623 and the top wall of the second abutment block 625 are both perpendicular to the sliding direction of the U-shaped frame 63, and the roller 64 can only move backward a little, and the roller 64 is elastic, so that when the splint 43 fixes the steel pipe, the roller 64 can always contact the side wall of the steel pipe, and the anti-deflection device 65 limits the steel pipe, making it difficult for the steel pipe to shake and deviate during the fixation process by the fixing device 40.

[0054] The anti-deflection device 65 includes a rotating shaft 651, a connecting rod 652, an anti-deflection roller 653, a torque spring 654, a first limit block 655, and a second limit block 656. When the U-shaped frame 63 moves centripetally, the U-shaped frame 63 can drive the anti-deflection device 65 to move centripetally. The six anti-deflection rollers 653 first contact and resist the steel pipe to form an elastic fixation, thereby reducing the surface damage or positioning jamming of the steel pipe caused by mechanical hard contact at the beginning, and then moving the U-shaped frame 63. The anti-deviation roller 653 moves backward under the force, and the torque spring 654 is deformed under the force until the rotating roller 64 abuts against the side wall of the steel pipe. The connecting rod 652 abuts against the side wall of the first limit block 655, so that the anti-deviation roller 653 will not be forced to move backward during the subsequent pushing process of the steel pipe, forming a rigid fixation. The front and rear sides around the side wall of the steel pipe are respectively abutted against the anti-deviation roller 653 and the rotating roller 64, making it difficult for the steel pipe to deviate during the pushing process, making the docking position of the two steel pipes more stable.
