Description
Technical Field
[0001] This invention relates to the field of welding positioning technology, specifically to a welding positioning device for elevator sliding guide shoes. Background Technology
[0002] With the development of society, elevators are being used more and more widely. An elevator is a vertical lifting machine powered by an electric motor. In daily life, 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, the elevator sliding guide shoes are an important component for the safe operation of elevators.
[0003] Patent publication number CN217942378U discloses a welding and positioning device for elevator sliding guide shoes, including a base plate, a positioning plate, and a positioning shaft. The positioning plate is vertically installed on the base plate and has a vertically set limiting surface. The base plate has a horizontally set receiving surface. The limiting surface and the receiving 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 receiving surface of the base plate. This device solves the problem that welding elevator sliding guide shoes relies on marking and positioning by hand before welding, which results in large errors, low yield, and low welding efficiency.
[0004] However, the device still has shortcomings: while it can reduce errors and improve yield, its positioning of the workpiece is mainly concentrated on the upper part, and it is difficult to effectively limit and stabilize the lower part of the workpiece. This can cause vibrations during operation, which can easily create tiny gaps between two workpieces placed side by side for welding, thus reducing the welding strength at the weld joint. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides an elevator sliding guide shoe welding and positioning device, which solves the problems mentioned in the background section.
[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: an elevator sliding guide shoe welding and positioning device, including a base, a plurality of positioning holes symmetrically and equidistantly opened on the top of the base, a driving component is provided on the left side of the base, an electric slide rail is provided on the top of one end of the back of the base, a control component is provided inside the electric slide rail, a transmission component is provided above the control component, and a welding component is provided on the top of the transmission component.
[0007] The base is provided with a gap-preventing device at the top, a misalignment prevention device is provided around the gap-preventing device, and an auxiliary device is provided inside the misalignment prevention device.
[0008] The anti-gap device includes an L-shaped limiting plate. The bottom of the L-shaped limiting plate is fixedly installed on the top left side of the base. A limiting groove is formed inside the L-shaped limiting plate. A guide plate is fixedly installed on the top of the base. The left side of the guide plate is fixedly installed on the right side of the L-shaped limiting plate. An electric rotating rod is rotatably installed on the top of the inner wall of the L-shaped limiting plate. A U-shaped plate is spirally connected through the outer wall of the electric rotating rod. The left side of the U-shaped plate is slidably installed on the right side of the drive assembly. Two L-shaped straight plates are symmetrically and fixedly installed on the top of the inner wall of the U-shaped plate. Several telescopic positioning columns are symmetrically and fixedly installed on the bottom of the L-shaped straight plates. An H-shaped plate is hinged to the bottom of the inner wall of the L-shaped straight plates. A soft rubber roller is rotatably installed on the top inner wall of the H-shaped plate. When welding the elevator sliding guide shoe, the sliding grooves of the two workpieces to be spliced and welded are slid horizontally along the inner wall of the guide plate, and the bottom of the workpiece contacts the top of the base. When the left side of the workpiece contacts the right side of the L-shaped limiting plate, the sliding stops. At this time, the spiral hole of the workpiece is aligned with the positioning hole on the top of the base. After the workpiece is placed, the electric... The moving rod, driven by an electric rotating rod, drives a threaded U-shaped plate to slide up and down along its outer wall via forward and reverse rotation. When the U-shaped plate slides down along the right side of the drive assembly, it drives the L-shaped straight plate to move synchronously. The L-shaped straight plate drives the telescopic positioning column to move downward. After the outer wall of the telescopic positioning column passes through the spiral hole of the workpiece, it enters 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, it causes the telescopic end of the telescopic positioning column to retract towards the fixed end. Subsequently, the electric slide rail drives the control assembly and the transmission assembly to move horizontally. The transmission assembly drives the welding assembly to move synchronously, and the welding assembly welds the workpiece. When the L-shaped straight plate moves downward, it drives the H-shaped plate to move synchronously. The H-shaped plate drives the soft rubber roller to move synchronously. When the soft rubber roller moves downward, its own arc surface contacts the outer wall of the workpiece, generating a resistance force. At this time, the soft rubber roller causes the hinge shaft of the H-shaped plate to generate a rotation force, and drives the H-shaped plate to flip away from the base. With the help of the torsion spring, the outer wall of the soft rubber roller is kept in contact with the outer wall of the workpiece.
[0009] According to the above technical solution, the electric rotating rod is designed for forward and reverse rotation, the outer walls of the two L-shaped straight plates are slidably installed inside the limiting groove of the L-shaped limiting plate, and several telescopic positioning columns are located directly above the positioning holes of the base. A torsion spring is provided between the bottom of the H-shaped plate and the bottom of the inner wall of the L-shaped straight plate.
[0010] According to the above technical solution, the anti-misalignment device includes an L-shaped square channel plate, an L-shaped telescopic plate, a U-shaped frame, and an arc-shaped block. The top of the L-shaped square channel plate is fixedly installed on the outer wall of the L-shaped straight plate near the base axis. The bottom of the L-shaped telescopic plate is slidably installed on the top of the base via 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's groove. An arc-shaped block is fixedly installed inside the U-shaped frame near the base axis. When the L-shaped straight plate moves downward, it drives the L-shaped square channel plate to move synchronously. During the downward movement of the L-shaped square channel plate... The bottom arc surface of the arc block will come into contact with the outer arc surface of the arc block and generate a resistance force. At this time, the arc block generates a force towards the center of the base by means of its own arc surface and the arc surface of the L-shaped square channel plate. The arc block pulls the U-shaped frame to move synchronously. The U-shaped frame pulls the L-shaped telescopic plate to slide closer to the center of the base. After the soft surface of the telescopic end of the L-shaped telescopic plate comes into contact with the middle of the outer wall of the workpiece, a resistance force is generated. At this time, the telescopic end of the L-shaped telescopic plate retracts into 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.
[0011] 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 near the center of the base, and a loop groove is opened inside the fixed end of the L-shaped telescopic plate. The arc surface of the arc block is located on the movement trajectory of the bottom arc surface of the L-shaped square groove plate.
[0012] According to the above technical solution, the anti-misalignment device also includes a transmission plate and a heating component. The top of the transmission plate is hinged to the side of the L-shaped straight plate away from the center of the base by a torsion spring. The bottom of the heating component is slidably mounted on the top of the base. The top of the heating component 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 component, causing its own hinge shaft to start rotating. At this time, the transmission plate pushes the heating component to move along the top of the base away from its center with the hinge shaft as the axis. The heating component starts to preheat the working area before the workpiece welding begins, and heats the workpiece away from its center with the help of the transmission plate during the workpiece positioning process.
[0013] According to the above technical solution, the auxiliary device includes a sliding plate, a hollow plate, and a flexible plate. The sliding plate is fixedly installed on the outer wall of the heating component on the side away from the base axis. The back of the hollow plate is fixedly installed on the front of the fixed end of the L-shaped telescopic plate. The top of the flexible plate is fixedly installed on the bottom of the hollow plate. The bottom arc surface of the flexible plate is located on the movement trajectory of the hollow plate. When the heating component moves away from the base axis, it drives the sliding plate to move synchronously. At the same time, the L-shaped telescopic plate drives the hollow plate to move closer to the base axis. The hollow plate drives the flexible plate to move synchronously. During the opposite movement of the flexible plate and the sliding plate, their arc surfaces abut against each other and cause the flexible plate to bend and deform. When the flexible plate bends to a certain extent, the sliding plate will pass over the flexible plate. During the process of the flexible plate restoring itself through its own toughness, it will swing back and forth to generate vibration.
[0014] According to the above technical solution, the auxiliary device further includes an L-shaped mesh plate, a friction wheel, a transmission rod, a few turbulence plates, 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 formed 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 base axis. A reciprocating spiral groove is formed at the end of the transmission rod near the friction wheel. Several of the turbulence plates are equidistantly 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 disc is slidably mounted on the outer wall of the spoiler. The disc is internally penetrated and movably mounted 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. 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 restricts the internal locking block of the disc through the reciprocating spiral groove on its outer wall. The reciprocating spiral groove drives the disc to push the scraper plate to slide along the outer wall of the spoiler. Then the scraper plate is reset by the spring force and repeats this process.
[0015] According to the above technical solution, the bottom of the L-shaped mesh plate is in contact with the top of the base, the outer wall of the friction wheel is in contact with the top of the base, the outer wall of the circular plate is slidably connected to the inner wall of the sliding groove of the L-shaped mesh plate, and the scraping plate is in contact with the outer wall of the circular plate at one end near the friction wheel.
[0016] This invention provides a welding and positioning device for elevator sliding guide shoes. It has the following advantages:
[0017] (1) The present invention achieves fixed-point positioning welding of workpieces by setting up an anti-gap device, using an L-shaped limiting plate, a guide plate, an electric rotating rod, a U-shaped plate, an L-shaped straight plate, a telescopic positioning column, an H-shaped plate and a soft rubber roller. The L-shaped straight plate horizontally limits the two sides of the outer wall of the workpiece, ensuring that the workpieces are horizontally side by side and welded together. At the same time, the bolt holes of the telescopic positioning column fit into the outer wall of the workpiece for limiting and stabilizing, avoiding the vibration generated during equipment operation, which would cause a small gap between the two workpieces to be welded, thereby reducing the weld strength. The soft rubber roller always adheres to the outer wall of the workpiece to generate a clamping force, and the H-shaped plate limits and supports the soft rubber roller, expanding the positioning and stabilizing range of the workpiece, avoiding gaps caused by external force interference, which would lead to poor weld quality.
[0018] (2) The present invention uses an anti-misalignment device, which combines an L-shaped straight plate, an L-shaped square groove plate, an L-shaped telescopic plate, a U-shaped frame, an arc block, a transmission plate and a heating component. The L-shaped telescopic plate effectively resists the workpiece, ensuring the static fit between the workpieces. At the same time, the spring built into the telescopic end of the L-shaped telescopic plate buffers and neutralizes the vibration generated during the movement of the equipment, preventing the irregular welding surfaces of the two workpieces from being slightly misaligned under the interference of vibration, which would cause the weld to bulge or sink in the weld area and increase the risk of weld cracking. At the same time, the heating component preheats the welding area, preventing the workpiece from being directly welded due to the temperature difference, which would cause a sudden increase in internal stress and increase the probability of slight deformation at the weld, thus reducing the yield.
[0019] (3) The present invention, through the setting of auxiliary devices, uses heating components, sliding plates, hollow plates, tough plates, L-shaped mesh plates, friction wheels, transmission rods, baffles, scrapers and circular plates to cooperate. By relying on the transmission of force, the soft surface of the L-shaped telescopic plate at the telescopic end and the soft surface of the soft rubber roller vibrate synchronously, so that the two can fit more closely when they come into contact with the irregular outer wall of the workpiece, further enhancing the original positioning stability effect and ensuring the stability of the workpiece. At the same time, the L-shaped mesh plate blocks the heat outlet of the heating component to prevent sparks or hot debris from splashing into the heating component during the welding process and causing damage. During the movement of the heating component, the rotation of the baffle plate accelerates the diffusion speed of the heat around it, thereby avoiding excessive local temperature difference. During the sliding of the scraper plate, the smoothness of the outer wall of the baffle plate is ensured, preventing hot debris from adhering to the outer wall of the baffle plate and causing solidification and erosion.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0030] Please see Figures 1-8 An embodiment of the present invention is: an elevator sliding guide shoe welding and positioning device, including a base 1, a plurality of positioning holes symmetrically and equidistantly opened on the top of the base 1, a drive component 2 is provided on the left side of the base 1, an electric slide rail 21 is provided on the top of one end of the back of the base 1, a control component 22 is provided inside the electric slide rail 21, a transmission component 3 is provided above the control component 22, and a welding component 31 is provided on the top of the transmission component 3.
[0031] The base 1 is provided with a gap-preventing device 4 at the top, a misalignment prevention device 5 is provided around the gap-preventing device 4, and an auxiliary device 6 is provided inside the misalignment prevention device 5.
[0032] The anti-gap device 4 includes an L-shaped limiting plate 41, the bottom of which is fixedly installed on the top left side of the base 1. A limiting groove is formed inside the L-shaped limiting plate 41. A guide plate 42 is fixedly installed on the top of the base 1. The left side of the guide plate 42 is fixedly installed on the right side of the L-shaped limiting plate 41. An electric rotating rod 43 is rotatably installed on the top of the inner wall of the L-shaped limiting plate 41. A U-shaped plate 44 is spirally connected through the outer wall of the electric rotating rod 43. The left side of the U-shaped plate 44 is slidably installed on the right side of the drive assembly 2. Two L-shaped straight plates 45 are symmetrically and fixedly installed on the top of the inner wall of the U-shaped plate 44. Several telescopic positioning posts 46 are symmetrically and fixedly installed on the bottom of the L-shaped straight plates 45. An H-shaped plate 47 is hinged to the bottom of the inner wall of the L-shaped straight plates 45. 7. A soft rubber roller 48 is rotatably mounted on the top inner wall. Through the above cooperation, the workpiece is positioned and welded at a fixed point. The L-shaped straight plate 45 is used to horizontally limit the two sides of the outer wall of the workpiece, ensuring that the workpieces are horizontally side by side and welded together. At the same time, the bolt holes of the telescopic positioning column 46 on the outer wall of the workpiece are matched with the bolt holes of the workpiece for limiting and stabilizing, avoiding 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 weld strength. Through the above cooperation, the soft rubber roller 48 always adheres to the outer wall of the workpiece to generate a clamping force, and the H-shaped plate 47 limits and supports the soft rubber roller 48, expanding the positioning and stabilizing range of the workpiece, and avoiding gaps caused by external force interference, which may lead to poor weld quality.
[0033] 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 holes of the base 1. A torsion spring is provided between the bottom of the H-shaped plate 47 and the bottom of the inner wall of the L-shaped straight plate 45.
[0034] During use, when welding the elevator sliding guide shoe, the two workpieces to be welded slide horizontally along the inner wall of the guide plate 42, with the bottom of the workpiece contacting the top of the base 1. Sliding stops when the left side of the workpiece contacts the right side of the L-shaped limiting plate 41. At this point, the spiral hole of the workpiece aligns with the positioning hole at the top of the base 1. After the workpiece is placed, the electric rotating rod 43 is activated. The electric rotating rod 43 drives the threaded U-shaped plate 44 to slide up and down along its outer wall via forward and reverse rotation. When the U-shaped plate 44 slides downwards along the right side of the drive assembly 2, it... The L-shaped straight plate 45 moves synchronously, driving the telescopic positioning column 46 downward. The outer wall of the telescopic positioning column 46 passes through the spiral hole of the workpiece and enters 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 resisting force is generated. As the L-shaped straight plate 45 continues to move downward, it causes the telescopic end of the telescopic positioning column 46 to retract towards the fixed end. Subsequently, the electric slide rail 21 drives the control component 22 and the transmission component 3 to move horizontally. The transmission component 3 drives the welding component 31 to move synchronously, and through the welding component 31... Welding is performed on the workpieces. The above-mentioned coordination achieves precise positioning and welding of the workpieces. The L-shaped straight plate 45 horizontally limits the two sides of the workpiece's outer wall, ensuring the workpieces are horizontally aligned and welded side-by-side. Simultaneously, the bolt holes on the outer wall of the telescopic positioning column 46, which fits into the workpiece, provide stability and prevent vibrations during equipment operation from creating tiny gaps between the two workpieces to be welded, thus reducing weld strength. When the L-shaped straight plate 45 moves downwards, it drives the H-shaped plate 47 to move synchronously, which in turn drives the soft rubber roller 48 to move synchronously. When the soft rubber roller 48 moves downward, its own curved surface comes into contact with the outer wall of the workpiece, generating a resistance force. At this time, the soft rubber roller 48 causes the hinge shaft of the H-shaped plate 47 to generate a rotational force, and drives the H-shaped plate 47 to flip away from the base 1. With the help of the torsion spring, the outer wall of the soft rubber roller 48 is always in contact with the outer wall of the workpiece. Through the above cooperation, the soft rubber roller 48 always in contact with the outer wall of the workpiece generates a clamping force, and the H-shaped plate 47 provides limiting support for the soft rubber roller 48, expanding the positioning stability range of the workpiece and avoiding gaps caused by external force interference, which would lead to poor weld quality.
[0035] Please see Figures 1-8 Based on the above embodiments, another embodiment of the present invention further includes an anti-misalignment device 5;
[0036] The anti-misalignment device 5 includes an L-shaped square channel plate 51, an L-shaped telescopic plate 52, a U-shaped frame 53, and an arc-shaped block 54. The top of the L-shaped square channel 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 via a spring. The bottom of the U-shaped frame 53 is fixedly installed on the bottom of the inner wall of the loop groove of the L-shaped telescopic plate 52. An arc-shaped block 54 is fixedly installed inside the U-shaped frame 53 near the axis of the base 1. Through the above cooperation, the L-shaped telescopic plate 52 effectively resists the workpiece, ensuring the static fit between the workpieces. At the same time, the spring built into the telescopic end of the L-shaped telescopic plate 52 buffers and neutralizes the vibration generated during the movement of the equipment, preventing the irregular welding surfaces of the two workpieces from being slightly misaligned under the interference of vibration, which could cause the weld to bulge or sink, increasing the risk of weld cracking.
[0037] 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 near the axis of the base 1, and a groove is provided inside the fixed end of the L-shaped telescopic plate 52. The arc surface of the arc block 54 is located on the movement trajectory of the bottom arc surface of the L-shaped square groove plate 51.
[0038] 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 by a torsion spring. The bottom of the heating component 56 is slidably mounted 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 by the heating component 56 to prevent the workpiece from being directly welded. The internal stress of the workpiece is increased due to the temperature difference, which increases the probability of slight deformation at the weld joint and thus reduces the yield.
[0039] In use, when the L-shaped straight plate 45 moves downward, it drives the L-shaped square channel plate 51 to move synchronously. During the downward movement of the L-shaped square channel plate 51, its bottom arc surface will contact the outer arc surface of the arc block 54, generating a resisting force. At this time, the arc block 54, guided by its own arc surface and the arc surface of the L-shaped square channel plate 51, generates a force to move towards the axis of the base 1. The arc block 54 pulls the U-shaped frame 53 to move synchronously. The U-shaped frame 53 pulls the L-shaped telescopic plate 52 to slide closer to the axis of the base 1. After the soft surface of the telescopic end of the L-shaped telescopic plate 52 contacts the middle of the outer wall of the workpiece, it generates a resisting force. At this time, the telescopic end of the L-shaped telescopic plate 52 retracts inward towards its 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 effectively resists the workpiece, ensuring the static fit between the workpieces. At the same time, the built-in telescopic end of the L-shaped telescopic plate 52... The springs buffer and neutralize the vibrations generated during the movement of the equipment, preventing slight misalignment of the irregular welding surfaces of the two workpieces under the interference of vibration, which could lead to bulging or depression in the weld area and increase the risk of weld cracking. When the L-shaped straight plate 45 moves downward, it drives the transmission plate 55 to move synchronously. The bottom of the transmission plate 55 is restricted by the heating component 56, causing its hinge shaft 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 shaft as the axis. The heating component 56 starts to preheat the working area before the workpiece welding begins, and heats it away from the workpiece during the workpiece positioning process with the help of the transmission plate 55. Through the above cooperation, the heating component 56 preheats the welding area, preventing the workpiece from directly welding and causing a sudden increase in internal stress due to temperature difference, which would increase the probability of slight deformation at the workpiece weld and reduce the yield.
[0040] Please see Figures 1-8 Based on the above embodiments, another embodiment of the present invention further includes an auxiliary device 6;
[0041] The auxiliary device 6 includes a sliding plate 61, a perforated plate 62, and a flexible plate 63. The sliding plate 61 is fixedly installed on the outer wall of the heating assembly 56 on the side away from the axis of the base 1. The back of the perforated plate 62 is fixedly installed on the front of the fixed end of the L-shaped telescopic plate 52. The top of the flexible plate 63 is fixedly installed on the bottom of the perforated plate 62. The bottom arc surface of the flexible plate 63 is located on the movement trajectory of the perforated 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 vibrate synchronously, so that the two can fit more tightly when they come into contact with the irregular outer wall of the workpiece, further enhancing the original positioning stability effect and ensuring the stability of the workpiece.
[0042] 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 L-shaped mesh plate 64 is fixedly installed 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 installed on the outer wall of the L-shaped mesh plate 64 near the heating component 56. The transmission rod 66 passes through and is fixedly installed on the side of the friction wheel 65 near the L-shaped mesh plate 64, away from the axis of the base 1. A reciprocating spiral groove is provided on the end of the transmission rod 66 near the friction wheel 65. The flow disturbance plates 67 are equidistantly installed on the outer wall of the transmission rod 66. The scraper plate 68... The outer wall is slidably mounted on the outer wall of the spoiler 67 by a transverse spring. The circular plate 69 is internally penetrated and movably mounted 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 by the L-shaped mesh plate 64 to prevent sparks or hot debris from splashing into 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 67 accelerates the diffusion speed of the heat around it, thereby avoiding excessive local temperature difference. During the sliding of the scraper plate 68, the smoothness of the outer wall of the spoiler 67 is maintained, preventing hot debris from adhering to the outer wall of the spoiler 67 and causing solidification and erosion.
[0043] 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 scraping plate 68 is in contact with the outer wall of the circular plate 69 at one end near the friction wheel 65.
[0044] In use, when the heating component 56 moves away from the axis of the base 1, it drives the sliding plate 61 to move synchronously. At the same time, the L-shaped telescopic plate 52 drives the hollow plate 62 to move closer to the axis of the base 1. The hollow plate 62 drives the flexible plate 63 to move synchronously. During the opposite movement of the flexible plate 63 and the sliding plate 61, their curved surfaces abut against each other, causing the flexible plate 63 to bend and deform. When the flexible plate 63 bends to a certain extent, the sliding plate 61 will pass over the flexible plate 63. During the process of the flexible plate 63 restoring itself through its own flexibility, it will swing back and forth to generate vibration. Through the above cooperation and 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 when they come into contact with the irregular outer wall of the workpiece, they can fit more tightly, further enhancing the original positioning stability effect and ensuring the stability of the workpiece. The sliding plate 61 drives the L-shaped mesh plate 64 to move away from the axis of the base 1. The L-shaped mesh plate 64 drives the friction wheel 65 along the direction of the base 1. The base 1 slides and rubs against the top and begins to rotate. The friction wheel 65 drives the transmission rod 66 to rotate, and the transmission rod 66 drives the baffle 67 to rotate. The baffle 67 disturbs the hot air outlet of the heating component 56. At the same time, the transmission rod 66 restricts the internal block of the circular plate 69 through the reciprocating spiral groove on its outer wall. The reciprocating spiral groove drives the circular plate 69 to push the scraper 68 to slide along the outer wall of the baffle 67. Then the scraper 68 is reset by the spring force and repeats. Through the above cooperation, the heat outlet of the heating component 56 is blocked by the L-shaped mesh plate 64 to prevent sparks or hot debris from the welding process 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 rotation of the baffle 67 accelerates the diffusion speed of the heat around it, thereby avoiding excessive local temperature difference. During the sliding of the scraper 68, the smoothness of the outer wall of the baffle 67 is maintained to prevent hot debris from adhering to the outer wall of the baffle 67 and causing solidification and erosion.
