Description

Technical Field

[0001] The invention relates to the technical field of welding positioning, in particular to a welding positioning device for a sliding guide shoe of an elevator. Background Art

[0002] With the development of society, elevators are used more and more widely. Elevators are vertical lifts powered by electric motors. Elevators are mainly used in multi-story buildings to carry people or goods. The widespread use of elevators has brought great convenience to people. At the same time, elevator sliding guide shoes are important components for the safe operation of elevators.

[0003] Patent announcement number CN217942378U discloses an elevator sliding guide shoe welding positioning device, including a base plate, a positioning plate and a positioning shaft. The positioning plate is vertically installed on the base plate. The positioning plate is provided with a vertically arranged limiting surface. The base plate is provided with a horizontally arranged supporting surface. The limiting surface and the supporting surface form an L-shaped structure. The positioning shaft is detachably installed on the limiting surface, and the axial direction of the positioning shaft is perpendicular to the limiting surface of the positioning plate. The axial direction of the positioning shaft is parallel to the supporting surface of the base plate. This solves the problem that when welding the elevator sliding guide shoe, the positioning is based on marking and manual placement before welding, resulting in large errors, low yield rate, and low welding efficiency.

[0004] However, the device still has some shortcomings: the device can reduce errors and improve the yield rate, but the positioning of the workpiece is mainly concentrated on the upper half, and it is difficult to effectively limit and stabilize the lower half of the workpiece, resulting in vibrations during the operation of the equipment, which can easily cause a tiny gap between two side-by-side workpieces to be welded, and easily reduce the welding strength of the weld. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an elevator sliding guide shoe welding positioning device, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above purpose, the present invention is implemented by the following technical solutions: an elevator sliding guide shoe welding positioning device, comprising a base, a plurality of positioning holes are symmetrically and equidistantly opened on the top of the base, a driving assembly is arranged on the left side of the base, an electric slide rail is arranged on the top of one end of the back of the base, a control assembly is arranged inside the electric slide rail, a transmission assembly is arranged above the control assembly, and a welding assembly is arranged on the top of the transmission assembly; The top of the base is provided with an anti-gap device, the periphery of the anti-gap device is provided with an anti-dislocation device, and the inner side of the anti-dislocation device is provided with an auxiliary device; The lock is then locked and the lock is locked. The lock is locked and the lock is locked. The lock is locked in place. The lock is locked and the lock is locked. The lock is locked. The lock is locked and the lock is locked. The electric rotating rod drives the U-shaped plate connected by the thread through positive and negative rotation to slide up and down along its outer wall. When the U-shaped plate slides downward along the right side of the driving component, it drives the L-shaped straight plate to move synchronously. The L-shaped straight plate drives the telescopic positioning column to move downward. The outer wall of the telescopic positioning column passes through the spiral hole of the workpiece and enters the interior of the positioning hole of the base. When the bottom of the telescopic end of the telescopic positioning column contacts the bottom of the inner wall of the positioning hole, a resistance force is generated. As the L-shaped straight plate continues to move downward, the telescopic end of the telescopic positioning column is caused to retract toward the inside of the fixed end. Subsequently, the control component and the transmission component are driven horizontally by the electric slide rail. The transmission component drives the welding component to move synchronously, and the workpiece is welded through the welding component; when the L-shaped straight plate moves downward, it drives the H-shaped plate to move synchronously, and the H-shaped plate drives the soft-surface rubber roller to move synchronously. When the soft-surface rubber roller moves downward, its own arc surface contacts the outer wall of the workpiece to generate a resistance force. At this time, the soft-surface rubber roller prompts the hinge shaft of the H-shaped plate to generate a rotational force, and drives the H-shaped plate to flip in the direction away from the base, and with the help of the torsion spring limit, the outer wall of the soft-surface rubber roller is always in contact with the outer wall of the workpiece.

[0007] According to the above technical solution, the electric rotating rod is designed for forward and reverse rotation, the two outer walls of the L-shaped straight plate are slidably installed inside the limiting groove of the L-shaped limiting plate, and several of the telescopic positioning columns are located directly above the positioning hole of the base, and a torsion spring is arranged between the bottom of the H-shaped plate and the bottom of the inner wall of the L-shaped straight plate.

[0008] According to the above technical solution, the anti-misalignment device includes an L-shaped square groove plate, an L-shaped telescopic plate, a U-shaped frame and an arc block. The top of the L-shaped square groove plate is fixedly installed on the outer wall of the L-shaped straight plate near the axis of the base. The bottom of the L-shaped telescopic plate is slidably installed on the top of the base through a spring. The bottom of the U-shaped frame is fixedly installed on the bottom of the inner wall of the L-shaped telescopic plate. An arc block is fixedly installed inside one end of the U-shaped frame near the axis of the base. When the L-shaped straight plate moves downward, it drives the L-shaped square groove plate to move synchronously. During the downward movement of the L-shaped square groove plate The arc surface at its bottom will contact the arc surface of the outer wall of the arc surface block to generate a resistance force. At this time, the arc surface block generates a force to move toward the axis of the base with the help of its own arc surface and the arc surface guide of the L-shaped square groove plate. The arc surface block pulls the U-shaped frame to move synchronously, and the U-shaped frame pulls the L-shaped telescopic plate to slide toward the axis of the base. The soft surface of the telescopic end of the L-shaped telescopic plate contacts the middle position of the outer wall of the workpiece and generates a resistance force. At this time, the telescopic end of the L-shaped telescopic plate shrinks toward the inside of its own fixed end, and the soft surface of the telescopic end of the L-shaped telescopic plate can better fit the irregular outer wall surface of the workpiece.

[0009] According to the above technical solution, the arc surface of the telescopic end of the L-shaped telescopic plate is aligned with the side of the L-shaped straight plate close to the axis of the base, and a circular groove is opened inside the fixed end of the L-shaped telescopic plate, and the arc surface of the arc surface block is located on the arc surface motion trajectory at the bottom of the L-shaped square groove plate.

[0010] According to the above technical solution, the anti-misalignment device also includes a transmission plate and a heating assembly. The top of the transmission plate is hinged to the side of the L-shaped straight plate away from the axis of the base through a torsion spring, and the bottom of the heating assembly is slidably installed on the top of the base. The top of the heating assembly is hinged to the bottom of the transmission plate. When the L-shaped straight plate moves downward, it drives the transmission plate to move synchronously. The bottom of the transmission plate is restricted by the heating assembly, causing its own hinge axis to start rotating. At this time, the transmission plate pushes the heating assembly along the top of the base away from its center with the hinge axis as the axis, and the heating assembly starts to preheat the working area before the workpiece welding begins, and uses the transmission plate to heat the workpiece away from the center during positioning.

[0011] According to the above technical scheme, the auxiliary device includes a sliding plate, a hollow plate and a tough plate. The sliding plate is fixedly installed on the outer wall of the heating component away from the axis of the base, the back of the hollow plate is fixedly installed on the front of the fixed end of the L-shaped telescopic plate, and the top of the tough plate is fixedly installed on the bottom of the hollow plate. The arc surface of the bottom of the tough plate is located on the movement trajectory of the hollow plate. When the heating component moves away from the axis of the base, it drives the sliding plate to move synchronously. At the same time, the L-shaped telescopic plate drives the hollow plate to move toward the axis of the base, and the hollow plate drives the tough plate to move synchronously. During the movement of the tough plate and the sliding plate in opposite directions, the arc surfaces of the two conflict with each other and cause the tough plate to bend and deform. When the tough plate bends to a certain amplitude, the sliding plate will pass over the tough plate, and the tough plate will swing back and forth to generate vibration during the process of resetting its own toughness.

[0012] According to the above technical solution, the auxiliary device also includes an L-shaped mesh plate, a friction wheel, a transmission rod, a spoiler plate, a scraper plate and a circular plate. The front of the L-shaped mesh plate is fixedly installed on the back edge of the sliding plate, and a sliding groove is provided inside the L-shaped mesh plate. The friction wheel is rotatably installed on the outer wall of the L-shaped mesh plate near the heating component. The transmission rod passes through and is fixedly installed on the side of the friction wheel near the L-shaped mesh plate at one end away from the axis of the base. A reciprocating spiral groove is provided at one end of the transmission rod near the friction wheel. Several spoilers are equidistant and fixedly installed on the outer wall of the transmission rod. The outer wall of the scraper plate is connected by a transverse spring. The sliding plate is installed on the outer wall of the spoiler, and the circular plate passes through and is movably installed on the outer wall of the reciprocating spiral groove of the transmission rod. The sliding plate drives the L-shaped mesh plate to move away from the axis of the base, and the L-shaped mesh plate drives the friction wheel to slide and rub along the top of the base and start to rotate. The friction wheel drives the transmission rod to rotate, and the transmission rod drives the spoiler to rotate. The spoiler disturbs the hot air outlet of the heating component. At the same time, the transmission rod limits the built-in block of the circular plate through the reciprocating spiral groove on its own outer wall, and drives the circular plate through the reciprocating spiral groove to push the scraper plate to slide along the outer wall of the spoiler. After that, the scraper plate is reset by the spring force and reciprocates.

[0013] According to the above technical solution, the bottom of the L-shaped mesh plate contacts the top of the base, the outer wall of the friction wheel contacts the top of the base, the outer wall of the circular plate is slidably connected to the inner wall of the L-shaped mesh plate sliding groove, and the scraper plate contacts the outer wall of the circular plate near one end of the friction wheel.

[0014] The present invention provides an elevator sliding guide shoe welding positioning device, which has the following beneficial effects:

[0015] (1) The present invention realizes the fixed-point positioning welding of the workpiece by setting up the anti-gap device through the cooperation of L-shaped limiting plate, wire plate, electric rotating rod, U-shaped plate, L-shaped straight plate, telescopic positioning column, H-shaped plate and soft-surface rubber roller. The L-shaped straight plate is used to horizontally limit the two sides of the outer wall of the workpiece to ensure that the workpieces are horizontally side by side and combined for welding. At the same time, the outer wall of the telescopic positioning column is used to fit the bolt hole of the workpiece to limit and stabilize, so as to avoid the vibration generated during the operation of the equipment, which may cause a small gap between the two workpieces to be welded, thereby reducing the welding firmness; and the soft-surface rubber roller is used to always fit the outer wall of the workpiece to generate a clamping force, and the H-shaped plate is used to limit and support the soft-surface rubber roller, so as to expand the positioning stability range of the workpiece, so as to avoid the gap between the workpiece due to external force interference, thereby causing poor weld quality.

[0016] (2) The present invention adopts the arrangement of an anti-misalignment device, and cooperates with an L-shaped straight plate, an L-shaped square groove plate, an L-shaped telescopic plate, a U-shaped frame, a curved surface block, a transmission plate and a heating component. The L-shaped telescopic plate effectively resists the workpieces to ensure the static fit between the workpieces. At the same time, the spring built into the telescopic end of the L-shaped telescopic plate is used to buffer and neutralize the vibration generated when the equipment moves, thereby preventing the irregular welding surfaces of the two workpieces from being slightly misaligned under the interference of vibration, resulting in convexity or concave phenomenon in some parts of the weld, thereby increasing the risk of weld cracking. At the same time, the heating component is used to preheat the welding area to prevent the workpiece from being directly welded. The internal stress of the workpiece increases suddenly due to the temperature difference, thereby increasing the probability of slight deformation at the welding point of the workpiece and reducing the yield rate.

[0017] (3) The present invention, through the setting of auxiliary devices, cooperates with the heating component, sliding plate, hollow plate, tough plate, L-shaped mesh plate, friction wheel, transmission rod, spoiler, scraper plate and circular plate, and relies on the transmission of force to cause the soft surface of the telescopic end of the L-shaped telescopic plate and the soft surface of the soft rubber roller to vibrate synchronously, so that the two can fit more closely when contacting the irregular outer wall of the workpiece, further enhancing the original positioning stabilization effect and ensuring the stability of the workpiece; at the same time, the heat outlet of the heating component is shielded by the L-shaped mesh plate to prevent sparks or hot debris from splashing into the interior of the heating component during welding and causing damage; at the same time, during the movement of the heating component, the spoiler rotates to accelerate the diffusion speed of the surrounding heat, thereby avoiding excessive local temperature difference; and during the sliding of the scraper plate, the smoothness of the outer wall of the spoiler is ensured to prevent the hot debris from adhering to the outer wall of the spoiler and causing solidification erosion.

The L-shaped straight plate 45 is used to limit the horizontal position of the two sides of the outer wall of the workpiece to ensure that the workpieces are horizontally side by side and combined for welding. At the same time, the outer wall of the telescopic positioning column 46 is used to fit the bolt hole of the workpiece for limiting stability, so as to avoid the vibration generated during the operation of the equipment, resulting in a small gap between the two workpieces to be welded, thereby reducing the firmness of the welding; through the above cooperation, the soft-surface rubber roller 48 is always in contact with the outer wall of the workpiece to generate a clamping force, and the H-shaped plate 47 limits the soft-surface rubber roller 48 to support it, so as to expand the positioning and stability range of the workpiece, and avoid the gap between the workpiece due to external interference, thereby causing poor weld quality.

[0022] The electric rotating rod 43 is designed for forward and reverse rotation. The outer walls of the two L-shaped straight plates 45 are slidably installed inside the limiting groove of the L-shaped limiting plate 41. Several telescopic positioning columns 46 are located directly above the positioning hole of the base 1. A torsion spring is arranged between the bottom of the H-shaped plate 47 and the bottom of the inner wall of the L-shaped straight plate 45.

[0023] When in use, when welding the elevator sliding guide shoe, the two workpieces that need to be spliced ​​and welded are horizontally slid along the inner wall of the guide plate 42, and the bottom of the workpiece contacts the top of the base 1. When the left side of the workpiece contacts the right side of the L-shaped limit plate 41, the sliding stops. At this time, the spiral hole of the workpiece is facing the positioning hole on the top of the base 1. When the workpiece is placed, the electric rotating rod 43 is started. The electric rotating rod 43 drives the U-shaped plate 44 connected by the thread to slide up and down along its outer wall through forward and reverse rotation. When the U-shaped plate 44 slides downward along the right side of the driving component 2, it brings The L-shaped straight plate 45 moves synchronously, and the L-shaped straight plate 45 drives the telescopic positioning column 46 to move downward. The outer wall of the telescopic positioning column 46 passes through the spiral hole of the workpiece and enters the interior of the positioning hole of the base 1. When the bottom of the telescopic end of the telescopic positioning column 46 contacts the bottom of the inner wall of the positioning hole, a resistance force is generated. As the L-shaped straight plate 45 continues to move downward, the telescopic end of the telescopic positioning column 46 is caused to retract toward the interior of the fixed end. Subsequently, the control component 22 and the transmission component 3 are driven horizontally by the electric slide rail 21. The transmission component 3 drives the welding component 31 to move synchronously, and through the welding component 31 The workpiece is welded, and the fixed-point positioning welding of the workpiece is realized through the above cooperation. The L-shaped straight plate 45 is used to horizontally limit the two sides of the outer wall of the workpiece to ensure that the workpieces are horizontally side by side and combined for welding. At the same time, the outer wall of the telescopic positioning column 46 is used to fit the bolt hole of the workpiece to limit and stabilize, so as to avoid the vibration generated during the operation of the equipment, resulting in a small gap between the two workpieces to be welded, thereby reducing the firmness of the welding; when the L-shaped straight plate 45 moves downward, it drives the H-shaped plate 47 to move synchronously, and the H-shaped plate 47 drives the soft-surface rubber roller 48 to move synchronously. When 48 moves downward, its own arc surface contacts the outer wall of the workpiece to generate a resistance force. At this time, the soft-surface rubber roller 48 prompts the hinge axis of the H-shaped plate 47 to generate a rotational force, and drives the H-shaped plate 47 to flip in the direction away from the base 1, and with the help of the torsion spring limit, the outer wall of the soft-surface rubber roller 48 is always in contact with the outer wall of the workpiece. Through the above cooperation, the soft-surface rubber roller 48 is always in contact with the outer wall of the workpiece to generate a clamping force, and the H-shaped plate 47 limits the support of the soft-surface rubber roller 48, thereby expanding the stable positioning range of the workpiece and avoiding the workpiece from generating gaps due to external interference, thereby causing poor weld quality.

[0024] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes an anti-misalignment device 5; The anti-dislocation device 5 includes an L-shaped square groove plate 51, an L-shaped telescopic plate 52, a U-shaped frame 53 and a curved surface block 54. The top of the L-shaped square groove plate 51 is fixedly installed on the outer wall of the L-shaped straight plate 45 near the axis of the base 1. The bottom of the L-shaped telescopic plate 52 is slidably installed on the top of the base 1 through a spring. The bottom of the U-shaped frame 53 is fixedly installed on the bottom of the inner wall of the circular groove of the L-shaped telescopic plate 52. The U-shaped frame 53 is fixedly installed with a curved surface block 54 at one end near the axis of the base 1. Through the above cooperation, the L-shaped telescopic plate 52 is relied on to effectively resist the workpiece to ensure the static fit between the workpieces. At the same time, the spring built into the telescopic end of the L-shaped telescopic plate 52 is used to buffer and neutralize the vibration generated during the movement of the equipment, so as to prevent the irregular welding surfaces of the two workpieces from being slightly dislocated under the interference of vibration, resulting in convexity or concave phenomenon in part of the weld, thereby increasing the risk of weld cracking.

[0025] The arc surface of the telescopic end of the L-shaped telescopic plate 52 is aligned with the side of the L-shaped straight plate 45 close to the axis of the base 1, and a circular groove is opened inside the fixed end of the L-shaped telescopic plate 52. The arc surface of the arc surface block 54 is located on the arc surface motion trajectory at the bottom of the L-shaped square groove plate 51.

[0026] The anti-misalignment device 5 also includes a transmission plate 55 and a heating component 56. The top of the transmission plate 55 is hinged to the side of the L-shaped straight plate 45 away from the axis of the base 1 through a torsion spring. The bottom of the heating component 56 is slidably installed on the top of the base 1. The top of the heating component 56 is hinged to the bottom of the transmission plate 55. Through the above cooperation, the welding area is preheated with the help of the heating component 56 to prevent the workpiece from being directly welded. The internal stress of the workpiece suddenly increases due to the temperature difference, which increases the probability of slight deformation at the welding point of the workpiece and reduces the yield rate.

[0027] When in use, the L-shaped straight plate 45 drives the L-shaped square groove plate 51 to move synchronously when moving downward. During the downward movement of the L-shaped square groove plate 51, the bottom arc surface of itself will contact the arc surface of the outer wall of the arc surface block 54 to generate a resistance force. At this time, the arc surface block 54 generates a force moving toward the axial direction of the base 1 with the help of its own arc surface and the arc surface guide of the L-shaped square groove plate 51. The arc surface block 54 pulls the U-shaped frame 53 to move synchronously, and the U-shaped frame 53 pulls the L-shaped telescopic plate 52 to slide toward the axial direction of the base 1. The soft surface of the telescopic end of the L-shaped telescopic plate 52 contacts the middle position of the outer wall of the workpiece and generates a resistance force. At this time, the telescopic end of the L-shaped telescopic plate 52 contracts toward the inside of its own fixed end, and the soft surface of the telescopic end of the L-shaped telescopic plate 52 can better fit the irregular outer wall surface of the workpiece. Through the above cooperation, the L-shaped telescopic plate 52 is effectively resisted to the workpiece to ensure the static fit between the workpieces. At the same time, with the help of the built-in The spring buffers and neutralizes the vibration generated when the equipment moves, preventing the irregular welding surfaces of the two workpieces from being slightly misaligned under the interference of vibration, resulting in convexity or concave phenomenon in the weld part, increasing the risk of weld cracking; when the L-shaped straight plate 45 moves downward, it drives the transmission plate 55 to move synchronously, and the bottom of the transmission plate 55 is restricted by the heating component 56, prompting its own hinge axis to start rotating. At this time, the transmission plate 55 pushes the heating component 56 along the top of the base 1 away from its center with the hinge axis as the axis, and the heating component 56 starts to preheat the working area before the workpiece welding starts. During the workpiece positioning process, the transmission plate 55 is used to heat the workpiece away from the transmission plate 55. Through the above cooperation, the welding area is preheated and heated with the help of the heating component 56, preventing the workpiece from directly welding. The internal stress of the workpiece increases due to the temperature difference, resulting in an increased probability of slight deformation at the welding point of the workpiece, thereby reducing the yield rate.

[0028] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes an auxiliary device 6; The auxiliary device 6 includes a sliding plate 61, a hollow plate 62 and a tough plate 63. The sliding plate 61 is fixedly installed on the outer wall of the heating component 56 away from the axis of the base 1. The back of the hollow plate 62 is fixedly installed on the front of the fixed end of the L-shaped telescopic plate 52. The top of the tough plate 63 is fixedly installed on the bottom of the hollow plate 62. The arc surface of the bottom of the tough plate 63 is located on the movement trajectory of the hollow plate 62. Through the above cooperation, the soft surface of the telescopic end of the L-shaped telescopic plate 52 and the soft surface of the soft rubber roller 48 are caused to vibrate synchronously by the transmission of force, so that the two can fit more closely when they contact the irregular outer wall of the workpiece, further enhancing the original positioning stabilization effect and ensuring the stability of the workpiece.

[0029] The auxiliary device 6 also includes an L-shaped mesh plate 64, a friction wheel 65, a transmission rod 66, a flow disturbance plate 67, a scraper plate 68 and a circular plate 69. The front of the L-shaped mesh plate 64 is fixedly mounted on the back edge of the sliding plate 61, and a sliding groove is provided inside the L-shaped mesh plate 64. The friction wheel 65 is rotatably mounted on the outer wall of the L-shaped mesh plate 64 near the heating component 56. The end of the transmission rod 66 away from the axis of the base 1 penetrates and is fixedly mounted on the side of the friction wheel 65 near the L-shaped mesh plate 64. A reciprocating spiral groove is provided at one end of the transmission rod 66 near the friction wheel 65. The flow disturbance plates 67 are equidistant and fixedly mounted on the outer wall of the transmission rod 66. The scraper plate 68 The outer wall is slidably installed on the outer wall of the spoiler 67 through a transverse spring, and the circular plate 69 penetrates inside and is movably installed on the outer wall of the reciprocating spiral groove of the transmission rod 66. Through the above cooperation, the heat outlet of the heating component 56 is blocked with the help of the L-shaped mesh plate 64 to prevent sparks or hot debris during welding from splashing into the interior of the heating component 56 and causing damage. At the same time, during the movement of the heating component 56, the spoiler 67 rotates to accelerate the diffusion speed of the surrounding heat to avoid excessive local temperature differences. In addition, the smoothness of the outer wall of the spoiler 67 is ensured during the sliding of the scraper plate 68 to prevent hot debris from adhering to the outer wall of the spoiler 67 and causing solidification erosion.

[0030] The bottom of the L-shaped mesh plate 64 contacts the top of the base 1 , the outer wall of the friction wheel 65 contacts the top of the base 1 , the outer wall of the circular plate 69 is slidably connected to the inner wall of the sliding groove of the L-shaped mesh plate 64 , and the scraper plate 68 contacts the outer wall of the circular plate 69 near one end of the friction wheel 65 .

[0031] When in use, when the heating component 56 moves away from the axial direction of the base 1, it drives the sliding plate 61 to move synchronously, and at the same time, the L-shaped telescopic plate 52 drives the hollow plate 62 to move toward the axial direction of the base 1, and the hollow plate 62 drives the tough plate 63 to move synchronously. During the opposite movement of the tough plate 63 and the sliding plate 61, the arc surfaces of the two conflict with each other and cause the tough plate 63 to bend and deform. When the tough plate 63 bends to a certain extent, the sliding plate 61 will pass over the tough plate 63, and the tough plate 63 will swing back and forth and vibrate during the process of resetting its own toughness. Through the above cooperation and relying on the transmission of force, the soft surface of the telescopic end of the L-shaped telescopic plate 52 and the soft surface of the soft rubber roller 48 vibrate synchronously, so that the two can fit more closely when contacting the irregular outer wall of the workpiece, further enhancing the original positioning stabilization effect and ensuring the stability of the workpiece; the sliding plate 61 drives the L-shaped mesh plate 64 to move away from the axial direction of the base 1, and the L-shaped mesh plate 64 drives the friction wheel 65 along The top of the base 1 slides and rubs and starts to rotate, the friction wheel 65 drives the transmission rod 66 to rotate, and the transmission rod 66 drives the spoiler 67 to rotate, and the spoiler 67 disturbs the hot air outlet of the heating component 56. At the same time, the transmission rod 66 limits the built-in block of the circular plate 69 through the reciprocating spiral groove on its outer wall, and drives the circular plate 69 through the reciprocating spiral groove to push the scraper plate 68 to slide along the outer wall of the spoiler plate 67. Then the scraper plate 68 is reset by the spring force and reciprocates in this way. Through the above cooperation, the heat outlet of the heating component 56 is blocked with the help of the L-shaped mesh plate 64 to prevent sparks or hot debris from splashing into the interior of the heating component 56 during the welding process and causing damage. At the same time, during the movement of the heating component 56, the rotation of the spoiler plate 67 accelerates the diffusion speed of the surrounding heat, thereby avoiding excessive local temperature difference, and ensuring the smoothness of the outer wall of the spoiler plate 67 during the sliding of the scraper plate 68 to prevent hot debris from adhering to the outer wall of the spoiler plate 67 and causing solidification erosion.
