Description

Technical Field

[0001] This invention relates to the field of welding technology, and more specifically, to a welding device for a snow sweeper roller bracket. Background Technology

[0002] As a key load-bearing component of snow removal machinery, the welding quality of the snow sweeper roller brush bracket directly affects the reliability and service life of the roller brush under extremely cold conditions; please refer to [link / reference needed]. Figure 1 Existing roller brush brackets are usually made of arc-shaped cover and side plates at both ends welded together. The welding of the inner folded edge of the side plate and the splice seam of the end edge of the cover is the core link of the overall structural strength.

[0003] However, due to the fact that the cover is a thin-walled arc-shaped component and the side plates are irregularly shaped structures with inner and outer folds, existing welding equipment is unable to achieve stable clamping, which easily leads to misalignment or uneven gaps between the ends of the cover and the side plates during splicing. Secondly, the splice seam extends in an arc shape, and existing welding equipment cannot ensure that the welding torch moves at a uniform and stable speed along the weld seam path. Fluctuations in welding speed and trajectory deviations result in inconsistent distribution of penetration depth, penetration width, and heat input, leading to poor weld quality repeatability. Furthermore, during the welding process, the side plates are prone to deflection due to their own weight or vibration, causing the inner folds to detach from the edge of the cover, ultimately affecting the welding strength and the overall dimensional accuracy of the bracket.

A connecting seat is hinged between the first hinge rod and the second hinge rod on the same side. A threaded rod is rotatably installed on one side of the connecting seat, and the threaded rod is threadedly connected to the connecting seat on the other side.

[0019] As a further embodiment of the present invention: an air blowing component is provided below the V-shaped placement platform. The air blowing component includes a mounting plate fixed to the V-shaped placement platform. A blower hood is installed on the mounting plate. A fan and an air inlet are respectively provided on both sides of the blower hood. An air outlet connected to the V-shaped placement platform is provided on the top of the blower hood. A through hole communicating with the air outlet is opened on the bottom surface of the V-shaped placement platform.

[0020] The beneficial effects of this invention are:

[0021] This invention is specifically designed for welding the inner folded edge of the side plate and the edge of the cover in the snow sweeper roller brush bracket. By using a V-shaped placement platform to adapt to the arc-shaped bottom surface of the cover, and side plate clamping parts and side plate positioning parts to adapt to the outer and inner folded edge structures of the side plate, stable clamping and welding of irregular thin-walled components are achieved, thereby effectively improving the consistency of weld quality.

[0022] Through the coordinated action of the liftable V-shaped placement platform and the side plate positioning component, when the V-shaped placement platform lifts the cover upward, it can automatically make the inner edge of the cover end fit with the inner folded edge of the side plate. At the same time, the side plate positioning component limits the cover and the side plate, ensuring that the ends of the two are aligned and spliced, effectively eliminating positional deviation and providing a high-precision reference for subsequent welding.

[0023] The drive motor drives the rotating shaft to rotate at a constant speed, which in turn drives the side plate positioning component to rotate synchronously in the circumferential direction. The welding gun, which is clamped on the side plate positioning component, is passively guided to move at a constant speed along the splice path, which effectively eliminates welding speed fluctuations and trajectory deviations. This makes the weld penetration, weld width and heat input distribution of the entire splice uniform and consistent, which greatly improves the repeatability and reliability of welding quality.

[0024] The side plate clamping component is rotatably connected to the rotating shaft. During the rotation of the rotating shaft and the side plate positioning component, the side plate clamping component and the side plate on it always maintain a constant vertical angle to prevent the side plate from deflecting or falling off due to the rotation shaft, and to ensure that the fit between the inner folded edge and the edge of the cover end is not damaged during the entire welding process.

[0046] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0047] Please see Figure 2 and Figure 3 This invention discloses a snow sweeper roller brush bracket welding equipment, which is used for welding the cover 110 and side plate 120 of the roller brush bracket 100; it includes a frame 200, a welding unit 300, a cover tooling unit 400 and a side plate tooling unit 500.

[0048] Please see Figure 4 The welding unit 300 is disposed on one side of the frame 200 and includes a mounting frame 310 and a welding torch 320 mounted on the mounting frame 310;

[0049] Please see Figure 5 The cover tooling unit 400 includes a V-shaped placement platform 430 that is vertically mounted on the frame 200, and the V-shaped placement platform 430 is used to assemble the cover 110.

[0050] Please see Figure 3 and Figure 6 The side plate tooling unit 500 is disposed on one side of the cover tooling unit 400, including a drive motor 510 fixed on the frame 200. The output end of the drive motor 510 is connected to a rotating shaft 520. A side plate clamping part 530 for assembling the side plate 120 is rotatably disposed at the end of the rotating shaft 520 away from the drive motor 510. A welding guide 540 adapted to the welding torch 320 is also coaxially fixed on the rotating shaft 520. A side plate positioning part 550 adapted to the cover 110 and the side plate 120 is disposed below the side plate clamping part 530.

[0051] Specifically, the cover 110 is assembled onto the V-shaped placement platform 430, and then a set of side plates 120 is assembled onto the side plate clamping component 530. The V-shaped placement platform 430 is lifted upwards until the inner edge of the end of the cover 110 is in contact with the inner folded edge 123 of the side plate 120. At this time, the side plate positioning component 550 also positions the cover 110 and the side plate 120 to ensure that the side plate 120 is aligned and spliced ​​with the end of the cover 110. Next, the welding torch 320 is clamped onto the side plate positioning component 550 so that the welding torch 320 is directly facing the starting position of one end of the splice seam, and then the welding torch 320 is turned on. Simultaneously, the drive motor 510 drives the rotating shaft 520 to rotate at a constant speed, thereby causing the side plate positioning component 550 to rotate synchronously in the circumferential direction. The side plate positioning component 550 can be used to guide the welding gun 320, so that it moves and welds at a constant speed along the splice seam path, ensuring the consistency of the splice seam welding effect. Since the side plate clamping component 530 is rotatably connected to the rotating shaft 520, during the rotation of the rotating shaft 520 and the side plate positioning component 550, the side plate clamping component 530 and the welding guide component 540 always maintain a constant vertical angle, thereby achieving precise positioning of the side plate 120 and the cover 110.

[0052] It should be noted that the present invention is specifically designed for welding the inner folded edge 123 of the side plate 120 and the end edge splice of the cover 110 in the snow sweeper roller brush bracket 100. By adapting the V-shaped placement platform 430 to the arc-shaped bottom surface of the cover 110, and the side plate clamping part 530 and the side plate positioning part 550 to the outer folded edge 121 and inner folded edge 123 of the side plate 120, stable clamping and welding of the irregular thin-walled component is achieved, thereby effectively improving the consistency of weld quality.

[0053] Through the coordinated action of the liftable V-shaped placement platform 430 and the side plate positioning component 550, when the V-shaped placement platform 430 lifts the cover 110 upward, it can automatically make the inner edge of the end of the cover 110 fit with the inner folded edge 123 of the side plate 120. At the same time, the side plate positioning component 550 limits the cover 110 and the side plate 120 to ensure that the ends of the two are aligned and spliced, effectively eliminating positional deviation and providing a high-precision reference for subsequent welding.

[0054] The drive motor 510 drives the rotating shaft 520 to rotate at a constant speed, which in turn drives the side plate positioning component 550 to rotate synchronously in the circumferential direction. The welding torch 320, which is clamped on the side plate positioning component 550, is passively guided to move at a constant speed along the splice path, which effectively eliminates welding speed fluctuations and trajectory deviations, making the weld penetration, weld width and heat input distribution of the entire splice uniform and consistent, and greatly improving the repeatability and reliability of welding quality.

[0055] The side plate clamping component 530 is rotatably connected to the rotating shaft 520. During the rotation of the rotating shaft 520 and the side plate positioning component 550, the side plate clamping component 530 and the side plate 120 on it always maintain a constant vertical angle to prevent the side plate 120 from deflecting or falling off due to the rotation of the rotating shaft 520, and to ensure that the fit between the inner folded edge 123 and the end edge of the cover 110 is not damaged during the entire welding process.

[0056] In one embodiment, please refer to Figure 4 The welding unit 300 further includes a mounting platform 330 fixed to one side of the frame 200. A guide rod 340 is horizontally fixed on the mounting platform 330. A slide table 350 is slidably mounted on the guide rod 340. A roller 360 adapted to the guide rod 340 is rotatably mounted on the slide table 350. A support frame 370 is vertically fixed at the upper end of the slide table 350. A lifting cylinder 380 is mounted on the top of the support frame 370. The mounting frame 310 is located at the extended end of the lifting cylinder 380.

[0057] Specifically, the lifting cylinder 380 drives the mounting frame 310 and welding torch 320 to descend to a suitable position, and then the welding torch 320 is clamped onto the side plate positioning component 550. A corrugated hose is connected between the torch head of the welding torch 320 and the mounting frame 310. When the rotating shaft 520 drives the side plate positioning component 550 to rotate circumferentially, the welding torch 320 can move freely relative to the mounting frame 310, so that there will be no interference between the welding torch 320 and the mounting frame 310. In addition, during the process of the side plate positioning component 550 pulling the welding torch 320, the entire slide table 350 and support frame 370 can passively move adaptively along the guide rod 340 under the traction action, thereby further avoiding interference between the welding torch 320 and the mounting frame 310.

[0058] It is worth noting that the lifting cylinder 380 drives the mounting bracket 310 and the welding torch 320 to descend vertically to the preset position, so that the welding torch 320 can be accurately clamped onto the side plate positioning component 550, and the torch head is directly facing the starting point of the splice, ensuring that the initial height and angle of the welding torch 320 are consistent each time welding, providing a stable premise for the arc starting quality of the weld.

[0059] The nozzle of the welding torch 320 is connected to the mounting bracket 310 via a corrugated hose, which allows the welding torch 320 to bend freely relative to the mounting bracket 310 when the side plate positioning component 550 drives the welding torch 320 to rotate circumferentially. This avoids motion interference or jamming between the welding torch 320 and the mounting bracket 310 under rigid connection, while allowing the welding torch 320 to accurately follow the splice seam trajectory.

[0060] The slide table 350 is slidably mounted on the horizontally fixed guide rod 340 via rollers 360, and the support frame 370 and lifting cylinder 380 move together with the slide table 350. When the side plate positioning component 550 pulls the welding torch 320 to move in the circumferential direction, the entire slide table 350 and the upper assembly can passively and adaptively move horizontally along the guide rod 340, thereby compensating for the horizontal component displacement of the welding torch 320 during its movement and avoiding positional interference between the welding torch 320 and the mounting frame 310 caused by changes in relative position.

[0061] Further, please refer to Figure 5 The cover tooling unit 400 also includes a sleeve 410 fixed on the frame 200. The bottom of the V-shaped placement platform 430 is provided with a lifting guide rod 420 that is slidably adapted to the sleeve 410. A lifting component 440 is also provided between the frame 200 and the V-shaped placement platform 430.

[0062] Specifically, the V-shaped placement platform 430 is driven to move up and down by the lifting component 440, while the lifting guide rod 420 slides relative to the sleeve 410, thereby realizing the height adjustment of the V-shaped placement platform 430 and the cover 110, so as to facilitate the assembly of the cover 110 and the splicing of the cover 110 and the side plate 120.

[0063] It should be noted that the lifting component 440 drives the V-shaped placement platform 430 to move up and down. At the same time, the lifting guide rod 420 slides and adapts to the sleeve 410 fixed on the frame 200, forming a double guide constraint, which effectively limits the lateral offset and rotation of the V-shaped placement platform 430 during the lifting process, ensuring that it only moves in a straight line in the vertical direction, thereby providing the cover 110 with a stable and precise height adjustment capability.

[0064] The V-shaped placement platform 430 is actively lifted by the lifting component 440, which allows the inner edge of the end of the cover 110 to automatically fit with the inner folded edge 123 of the side plate 120. At the same time, it works with the side plate positioning component 550 to complete the splicing and positioning, which improves the docking efficiency and consistency and avoids the defects of fitting gap or misalignment caused by height deviation.

[0065] The lifting component 440 can drive the V-shaped placement platform 430 to descend to a low position, providing ample operating space for the insertion or removal of the cover 110; when it rises to a high position, it completes the splicing with the side plate 120; at the same time, by controlling the end position of the stroke of the lifting component 440, it can be adapted to cover 110 with different diameters or arc radii.

[0066] In yet another embodiment, please refer to Figure 6 and Figure 7 The side plate clamping component 530 includes a rotating ring 531 rotatably sleeved on the rotating shaft 520, and a clamping plate 532 is fixedly connected below the rotating ring 531. The clamping plate 532 is provided with a first positioning pin 533 that is adapted to the second pin hole 122 of the side plate 120.

[0067] Specifically, please refer to Figure 10 The clamping plate 532 is attached to the upper surface of the outer folded edge 121 of the side plate 120, and the first positioning pin 533 is inserted into the corresponding second pin hole 122, thereby realizing the assembly of the side plate 120 and the side plate clamping part 530. At this time, the side plate 120 is kept in a vertical state. The cover 110 is driven to rise vertically by the V-shaped placement table 430, so that the end edge of the cover 110 can be aligned and spliced ​​with the inner folded edge 123 of the side plate 120.

[0068] It should be noted that the rotating ring 531 is rotatably sleeved on the rotating shaft 520, so that the side plate clamping part 530 can rotate freely relative to the rotating shaft 520. When the rotating shaft 520 and the welding guide 540 drive the welding torch 320 to rotate circumferentially, the clamping plate 532 and the side plate 120 on it maintain a constant vertical angle by gravity or counterweight, which prevents the side plate 120 from flipping synchronously with the rotating shaft 520. This ensures that the inner folded edge 123 and the end edge of the cover 110 are always tightly fitted during the entire welding process and will not be misaligned or separated due to rotation.

[0069] The first positioning pin 533 on the clamping plate 532 and the second pin hole 122 on the side plate 120 form a positioning pair. The side plate 120 can be assembled simply by fitting the clamping plate 532 against the upper surface of the outer folded edge 121 of the side plate 120 and inserting the first positioning pin 533. The clamping plate 532 and the upper surface of the outer folded edge 121 of the side plate 120 not only restrict the horizontal movement and rotation of the side plate 120 through the first positioning pin 533, but also determine the installation reference height of the side plate 120 in the vertical direction through surface contact. When the V-shaped placement platform 430 lifts the cover 110, the end edge of the cover 110 can accurately reach the height position that aligns with the inner folded edge 123 without additional adjustment of the vertical position of the side plate 120.

[0070] Since the side plate 120 is fixed in a vertical position by the clamping plate 532 and the height reference is known, when the V-shaped placement platform 430 drives the cover 110 to rise vertically, the inner edge of the end of the cover 110 can automatically fit with the inner folded edge 123 of the side plate 120, thereby improving the docking efficiency and consistency.

[0071] Further, please refer to Figure 6 and Figure 8The welding guide 540 includes a flipping rod 541 fixed to a rotating shaft 520. A flipping table 542 is fixed to one end of the flipping rod 541 away from the rotating shaft 520. A telescopic guide rod 543 is slidably passed through the flipping table 542. A clamping table 544 is fixedly connected to one end of the telescopic guide rod 543 away from the flipping table 542. A clamping hole 547 adapted to the welding torch 320 is opened on the clamping table 544. A pressure roller 548 adapted to the inner folded edge 123 is rotatably installed at the bottom of the clamping table 544. A limit plate 545 is provided at one end of the telescopic guide rod 543 away from the clamping table 544. A first spring 546 is provided between the flipping table 542 and the clamping table 544. The first spring 546 is movably sleeved on the telescopic guide rod 543.

[0072] Specifically, please refer to Figure 11 After the side plate 120 is assembled onto the side plate clamping component 530, under the elastic force of the first spring 546, the clamping table 544 is pushed away from the flipping table 542, so that the pressure roller 548 at the lower end of the clamping table 544 presses against the inner folded edge 123 of the side plate 120. The welding torch 320 is clamped into the clamping hole 547, so that the welding torch 320 is directly facing the splice seam between the inner folded edge 123 and the cover 110. When the rotating shaft 520 rotates, the entire welding guide component 540 can rotate circumferentially relative to the side plate 120 with the rotating shaft 520, so that the welding torch 320 can be fed along the arc-shaped splice seam path. At the same time, the pressure roller 548 always rolls and fixes the inner folded edge 123, so that the side plate 120 and the cover 110 always keep in close contact, ensuring that the welding part of the welding torch 320 will not be misaligned or slipped, thus improving the stability of the welding effect.

[0073] It is worth noting that the first spring 546 is sleeved on the telescopic guide rod 543, which always pushes the clamping table 544 away from the flipping table 542, so that the pressure roller 548 at the lower end of the clamping table 544 always presses against the inner folded edge 123 of the side plate 120. During the circumferential rotation of the welding guide 540 driven by the rotating shaft 520, the pressure roller 548 rolls along the inner folded edge 123 and continuously applies pressure, thereby fixing the splicing surface of the side plate 120 and the cover 110, effectively preventing relative misalignment and slippage caused by welding thermal stress or vibration, and ensuring that the splicing gap is always consistent.

[0074] The telescopic guide rod 543 slides through the tilting table 542. With the elastic extension and contraction of the first spring 546, the clamping table 544 and the pressure roller 548 can automatically adjust the extension length according to the actual height of the inner folded edge 123 or local unevenness. This eliminates the phenomenon of excessive tightness or separation between the pressure roller 548 and the inner folded edge 123 caused by workpiece manufacturing tolerances or assembly cumulative errors, ensuring stable and reliable clamping force, while avoiding damage to the thin-walled side plate caused by rigid clamping.

[0075] When the pressure roller 548 abuts against the inner folded edge 123, the welding torch 320, which is clamped in the clamping hole 547, automatically aligns with the starting position of the splice seam between the inner folded edge 123 and the cover 110; when the rotating shaft 520 rotates, the welding torch 320 moves synchronously with the clamping table 544 along the arc splice seam path.

[0076] The pressure roller 548 adopts a rotating mounting structure and makes rolling contact as it moves circumferentially along the inner folded edge 123, which reduces the frictional resistance with the surface of the side plate 120 and allows the welding guide 540 to be smoothly driven by the rotating shaft 520, avoiding the influence of resistance fluctuations on the uniform movement of the welding torch 320. At the same time, the rolling contact will not scratch the anti-corrosion or coating on the surface of the inner folded edge 123, maintaining the corrosion resistance of the snow sweeper roller bracket.

[0077] Furthermore, please refer to Figure 6 and Figure 9 The side plate positioning component 550 includes a T-shaped bracket 551 fixed below the clamping plate 532. The T-shaped bracket 551 is provided with a vertical slide groove 552 and a horizontal slide groove 553. A vertical slider 554 is slidably installed in the vertical slide groove 552, and a horizontal slider 555 is slidably installed in the horizontal slide groove 553. A connecting rod 556 is hinged between the vertical slider 554 and the horizontal slider 555. A pressure plate 558 is fixedly connected to the lower end of the vertical slider 554 through a connecting plate 557. A positioning plate 559 adapted to the outer wall of the side plate 120 is fixedly connected to the horizontal slider 555. A sliding rod 5510 is provided in the horizontal slide groove 553. A second spring 5511 is sleeved on the end of the sliding rod 5510 away from the vertical slide groove 552.

[0078] Specifically, please refer to Figure 10 In the initial state, due to the elastic force of the second spring 5511, the horizontal slider 555 is always located on the side of the horizontal slide groove 553 close to the T-shaped bracket 551, and the vertical slider 554 is located at the lower end of the vertical slide groove 552. When the V-shaped placement platform 430 is lifted, causing the cover 110 to rise, the V-shaped placement platform 430 gradually approaches the pressure plate 558 until the pressure plate 558 contacts the bottom surface inside the V-shaped placement platform 430. As the V-shaped placement platform 430 continues to rise, the connecting plate 557 gradually retracts into the vertical slide groove 552, thereby driving the vertical slider 554. 4. The vertical slide 552 slides upward, and then, under the push of the connecting rod 556, the horizontal slider 555 slides horizontally along the horizontal slide 553, so as to drive the positioning plate 559 to gradually approach the outer wall of the side plate 120 until the positioning plate 559 is in contact with the outer wall of the side plate 120. At this time, the cover 110 is also just spliced ​​with the side plate 120. Thus, the positioning plate 559 is used to provide horizontal support and positioning for the side plate 120, ensuring the accuracy of the splicing position of the side plate 120 and the cover 110, while keeping the vertical posture of the side plate 120 unchanged, providing a stable foundation for subsequent welding.

[0079] It should be noted that the side plate positioning component 550 is triggered by contact between the V-shaped placement platform 430 and the pressure plate 558 during the upward movement. When the V-shaped placement platform 430 lifts the cover 110, the pressure plate 558 is pushed upward. Through the transmission of the vertical slider 554, the connecting rod 556 and the horizontal slider 555, the positioning plate 559 is automatically driven to move horizontally and fit against the outer wall of the side plate 120.

[0080] The vertical slider 554 and the horizontal slider 555 are hinged together by the connecting rod 556. When the vertical slider 554 slides upward due to the pressure plate 558 being lifted, the connecting rod 556 pushes the horizontal slider 555 to move horizontally outward along the horizontal slide groove 553, thereby driving the positioning plate 559 to clamp the side plate 120 from the side, ensuring that the positioning plate 559 is just close to the outer wall of the side plate 120 at the moment of splicing.

[0081] The slide bar 5510 and the second spring 5511 installed in the transverse slide groove 553 keep the transverse slider 555 close to the side of the T-shaped bracket 551 (i.e., the position where the positioning plate 559 is away from the side plate 120) in the initial state. When the V-shaped placement platform 430 descends, the second spring 5511 pushes the transverse slider 555 to reset, and at the same time, the connecting rod 556 drives the vertical slider 554 and the pressure plate 558 to extend downward, so that the positioning plate 559 automatically disengages from the outer wall of the side plate 120.

[0082] By designing the length of the connecting plate 557, the vertical slide 552, and the geometric dimensions of the connecting rod 556, it is possible to precisely control that when the pressure plate 558 is pushed by the inner bottom surface of the V-shaped placement platform 430 and the vertical slider 554 slides up to a certain position, the positioning plate 559 is just in contact with the outer wall of the side plate 120, and at this time the cover 110 is also just in contact with the inner folded edge 123 of the side plate 120.

[0083] The positioning plate 559 is in surface contact with the outer wall of the side plate 120. During the welding heat input and cooling shrinkage process, it can provide stable lateral support for the side plate 120, preventing the side plate 120 from bending and deforming outward or inward due to thermal stress. This ensures that the splice seam between the inner folded edge 123 and the end edge of the cover 110 maintains the set butt gap and perpendicularity throughout the welding process, thus improving the weld formation quality.

[0084] In further embodiments, please refer to Figure 12 The bottom of the V-shaped placement platform 430 is provided with a base 431, and the base 431 is provided with a second positioning pin 432 that is adapted to the first pin hole 111 of the cover 110.

[0085] Specifically, the cover 110 is placed inside the V-shaped placement platform 430, so that the second positioning pin 432 is inserted into the corresponding first pin hole 111, thereby realizing the assembly and positioning of the cover 110 and the V-shaped placement platform 430.

[0086] Further, please refer to Figure 13 The lifting member 440 includes a first hinge seat 441 fixed on the frame 200 and a second hinge seat 442 disposed at the bottom of the V-shaped placement platform 430. The first hinge seat 441 is symmetrically hinged with a first hinge rod 443 on both sides, and the second hinge seat 442 is symmetrically hinged with a second hinge rod 444 on both sides. A connecting seat 445 is hinged between the first hinge rod 443 and the second hinge rod 444 on the same side. A threaded rod 446 is rotatably mounted on one side of the connecting seat 445, and the threaded rod 446 is threadedly connected to the connecting seat 445 on the other side.

[0087] Specifically, by rotating the threaded rod 446, the connecting seats 445 on both sides gradually move closer together, which causes the first hinge rod 443 and the second hinge rod 444 on both sides to swing towards the middle, thereby driving the second hinge seat 442 to rise upward, so as to realize the lifting action of the V-shaped placement platform 430.

[0088] It is worth noting that a second positioning pin 432 is provided on the base 431 at the bottom of the V-shaped placement platform 430, which forms a positioning pair with the first pin hole 111 preset on the cover 110. When the cover 110 is placed into the V-shaped placement platform 430, the second positioning pin 432 automatically inserts into the first pin hole 111, which restricts the axial movement and circumferential rotation of the cover 110 in the V-groove, ensuring that the end edge of the cover 110 and the inner folded edge 123 of the side plate 120 are at the same height after each clamping.

[0089] The lifting component 440 adopts a scissor-type linkage structure formed by the first hinge rod 443 and the second hinge rod 444 hinged through the connecting seat 445. It works with the threaded rod 446 to drive the connecting seats 445 on both sides to move closer or further apart. When the threaded rod 446 is rotated, the connecting seats 445 on both sides move along the thread axis, pushing the hinge rod to swing and make the second hinge seat 442 rise and fall vertically. Since the threaded drive has a self-locking characteristic, the V-shaped placement platform 430 can be held at any height position after the rotation stops, without the need for continuous power supply or additional locking device, thus avoiding the cover 110 from falling accidentally due to external force or vibration during the welding process.

[0090] The first hinge rod 443 and the second hinge rod 444 are symmetrically arranged on both sides of the first hinge seat 441 and the second hinge seat 442, forming a double parallelogram mechanism. When the V-shaped placement platform 430 carries the cover 110 and is subjected to the reaction force of the side plate positioning member 550, the symmetrical linkage structure can automatically balance the load difference between the left and right sides, ensuring that the V-shaped placement platform 430 always maintains a horizontal posture during the lifting process, and avoiding misalignment of the cover 110 and the side plate 120 due to tilting.

[0091] Furthermore, please refer to Figure 14Below the V-shaped placement platform 430, an air blowing component 450 is also provided. The air blowing component 450 includes a mounting plate 451 fixed on the V-shaped placement platform 430. A blower hood 452 is installed on the mounting plate 451. A fan 453 and an air inlet 454 are respectively provided on both sides of the blower hood 452. An air outlet 455 that connects to the V-shaped placement platform 430 is provided on the top of the blower hood 452. A through hole 433 communicating with the air outlet 455 is opened on the bottom surface of the V-shaped placement platform 430.

[0092] Specifically, the air outlet 455 and the through hole 433 are directly opposite the joint between the cover 110 and the side plate 120. During the welding process, the fan 453 draws air from the air inlet 454 into the blower hood 452, and then blows the airflow through the air outlet 455 and the through hole 433 into the V-shaped placement platform 430, thereby blowing air at the joint, reducing the temperature of the welding area and blowing away the welding slag.

[0093] The specific embodiments of the present invention have been described above. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention, all of which are within the protection scope of the present invention.
