Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of welding equipment, and particularly relates to a welding equipment with a spatter protection function. BACKGROUND

[0002] In various industrial manufacturing and processing scenes, welding as a key connection process is widely used in the manufacturing, maintenance and assembly of metal structural parts. Whether it is traditional arc welding, gas shielded welding, or emerging laser welding, plasma welding and other welding technologies, high-temperature molten metal spatter and welding slag will inevitably be produced during the welding process. These spatters and slag not only seriously affect the welding quality, but also pose a threat to the safety of operators, and pollute the working environment, increasing the subsequent cleaning cost.

[0003] During the welding process, molten metal will spatter out from the weld area in the form of small particles under the action of high temperature and arc force. If these spatters adhere to the surface or surrounding base material of the weld, they will form hard particles after cooling. In the subsequent welding process, these particles may cause unstable arc, causing porosity, slag inclusion and other welding defects, reducing the strength and density of the weld, and seriously affecting the mechanical properties and service life of the welded structure.

[0004] Welding spatter is extremely high in temperature, usually reaching hundreds of degrees or even thousands of degrees. In some production workshops with high requirements for environmental cleanliness, such as electronic manufacturing workshops, the pollution problem of welding spatter and slag is more prominent, and may even affect the normal progress of the entire production process. SUMMARY

[0005] The present application aims to provide a welding equipment with a spatter protection function to solve the problems in the prior art.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical scheme:

[0007] The welding equipment with a spatter protection function comprises a mounting box, an adjusting unit, a welding unit, a protection unit and a cleaning unit. The mounting box is placed on a horizontal ground. The mounting box is fixedly connected with the adjusting unit. The welding unit is fixedly connected with the mounting box. The protection unit is fixedly connected with the welding unit. The protection unit is fixedly connected with the cleaning unit. The protection unit has a function of preventing spatter from spattering outwards.

[0008] The mounting box is used to install and fix the adjustment unit, welding unit, and protective unit. The adjustment unit is used to adjust the placement position of the workpiece, the welding unit is used to weld the workpiece, the protective unit is used to prevent spatter from splashing, and the cleaning unit is used to clean the welding slag. After the workpiece is placed on the adjustment unit and positioned in the predetermined position by the adjustment unit, the welding unit performs welding while the protective unit intercepts the welding spatter generated during welding, preventing the welding slag from sticking to the unwelded workpiece and affecting the welding quality, while also preventing the spatter from causing injury to the workers. Subsequently, the cleaning unit cleans the welding slag.

[0009] Furthermore, the adjustment unit includes a mounting frame, a fixing plate, a conveying motor, a screw, and a welding table. The mounting frame is fixedly installed inside the mounting box, the fixing plate is fixedly installed on the mounting frame, the fixed end of the conveying motor is fixedly installed on the fixing plate, the output end of the conveying motor is fixedly connected to the screw, and the screw is threadedly connected to the welding table.

[0010] After the workpiece is placed on the welding table, the controller starts the conveyor motor, which drives the screw to rotate, so that the welding table slides back and forth on the mounting frame. The welding table is then moved to the designated position to complete the preparation work before welding.

[0011] Furthermore, the welding unit includes a mounting plate, an electric telescopic rod, a connecting block, a long plate, and an output motor. The mounting plate is fixedly installed on the inner surface of the mounting box at the end away from the horizontal ground. The fixed end of the electric telescopic rod is fixedly installed on the mounting plate. The telescopic end of the electric telescopic rod is fixedly connected to the connecting block. The long plate is fixedly installed on the mounting plate. The fixed end of the output motor is fixedly installed on the long plate.

[0012] Furthermore, the welding unit also includes an electric telescopic rod II, a connecting plate, an electric push rod, a straight rod, and a welding torch. The output end of the output motor is fixedly connected to the fixed end of the electric telescopic rod II. The fixed end of the electric telescopic rod II is slidably mounted on the long plate. The output end of the electric telescopic rod II is fixedly connected to the connecting plate. The fixed end of the electric push rod is fixedly mounted on the connecting plate. The output end of the electric push rod is fixedly connected to the straight rod. The welding torch is fixedly mounted on the end of the straight rod. The connecting plate away from the horizontal ground is rotatably connected to the connecting block. The connecting plate near the horizontal ground is fixedly connected to the protective unit.

[0013] After the workpiece is placed, the controller controls the electric telescopic rod one on the mounting plate and the electric telescopic rod two on the long plate to extend, driving the connecting block to move downwards to the approximate welding position for coarse adjustment. This causes the connecting plate and the electric push rod to move downwards. At this time, the controller controls the electric push rod to extend, driving the welding torch on the straight rod to continue moving downwards to the designated welding position for fine adjustment. The welding torch then operates to weld the workpiece. During the continued welding process, the controller controls the output motor to start, thereby driving the electric telescopic rod two to move left and right, changing the position of the welding torch and achieving continuous welding of the workpiece.

[0014] Furthermore, the protective unit includes a protective cover, a spiral plate, a rotating drum, a turntable, a guide rod, a return spring, and a conductive ring. The protective cover is fixedly connected to a connecting plate near the horizontal ground. The spiral plate is fixedly installed inside the protective cover. The rotating drum is threadedly connected to the straight rod and fixedly connected to the turntable. One end of the guide rod is rotatably connected to the rotating drum, and the other end is fixedly connected to one end of the return spring. The other end of the return spring is fixedly connected to the conductive ring. The conductive ring is slidably connected to the guide rod. An induction coil is evenly wound on the guide rod. The protective cover is fixedly connected to the cleaning unit. The rotating drum is made of magnet.

[0015] Furthermore, the protective unit also includes a pull rope, a sliding block, a fixed disc, a flexible cylinder, a telescopic spring, a memory spring rod, and a ring cylinder. One end of the pull rope is fixedly connected to a conductive ring, and the other end of the pull rope is fixedly connected to a sliding block. The fixed disc is fixedly mounted on a straight rod and has a nozzle. An electric valve is installed at the nozzle, and the conductive ring is electrically connected to the electric valve. One end of the flexible cylinder is fixedly connected to a turntable, and the other end is slidably connected to the fixed disc. One end of the telescopic spring is fixedly connected to the turntable, and the other end is rotatably connected to the fixed disc. One end of the memory spring rod is fixedly connected to the end of the protective cover near the horizontal ground, and the other end is fixedly connected to the ring cylinder.

[0016] After adjusting the welding torch to the designated welding position, the ring cylinder is now parallel to the welding table. Due to the large amount of heat generated during welding, the memory spring rod expands and elongates. This causes the memory spring rod to increase the clamping force between the ring cylinder and the welding table, ensuring a tight seal and preventing splashes from rolling out of the gaps. As the controller controls the guide fan blades to rotate forward, the magnetic force drives the rotating cylinder to rotate synchronously and move downwards. Simultaneously, centrifugal force causes the sliding block to rotate along the spiral plate. Since the diameter of the spiral plate increases as it descends, the sliding block pulls the pull rope, causing the conductive ring to slide along the smooth rod while simultaneously pulling the reset spring. As the spring extends, the effective number of turns in the induction coil decreases, and the current gradually increases. This increases the current supplied to the electric valve at the nozzle. When the current reaches the set value, the electric valve opens. Meanwhile, as the rotating drum descends, it drives the turntable to rotate and slide downwards, squeezing the flexible cylinder and the telescopic spring. Under the pressure of the turntable, the water inside the flexible cylinder is atomized and sprayed out through the nozzle. When the guide fan blades rotate in the forward direction, the controller controls the electric valve of the water supply tank to close, generating air jets that quickly spray the mist towards the welding area. This rapidly cools the welding area inside the protective cover under the sealed condition, while reducing the generation of spatter such as welding slag.

[0017] Furthermore, the cleaning unit includes a guide fan blade, a drive gear, a driven gear, an internal gear ring, a round rod, a scraper, a bent rod, a sleeve, and a water tank. The guide fan blade is fixedly mounted on the straight rod, the drive gear is fixedly mounted on the straight rod, the driven gear meshes with the drive gear, the driven gear is fixedly connected to the internal gear ring, the internal gear ring is fixedly mounted inside the protective cover, one end of the round rod is fixedly connected to the scraper, and the other end is fixedly connected to the driven gear, one end of the bent rod is fixedly connected to the driven gear, and the other end is fixedly connected to the sleeve, the sleeve is fitted onto the straight rod, one end of the water tank is fixedly connected to the end of the protective cover away from the horizontal ground, and the other end of the water tank is fixedly connected to the connecting plate, the end of the guide fan blade near the rotating cylinder is made of magnet, the water tank is equipped with an electric valve, and the water tank extends into the flexible cylinder through a pipe.

[0018] When the controller controls the guide fan blades to rotate in the reverse direction, on the one hand, the controller controls the electric valve of the water tank to open, and the water inside the water tank is transported to the flexible cylinder through the conduit. At the same time, under the action of centrifugal force, the sliding block is driven to slide upward along the spiral plate. At this time, under the action of the return spring's own restoring force, the conductive ring is pulled to the left. At this time, the current supplied to the electric valve at the nozzle decreases, and the nozzle closes and stops spraying. On the other hand, the guide fan blades drive the rotating cylinder to rotate in the reverse direction. At this time, the rotating cylinder drives the turntable to rotate upward. With the action of the extension spring's own restoring force, the turntable rotates upward, increasing the volume of the flexible cylinder for water storage. During the rotation of the guide fan blades, the driving gear rotates, causing the driven gear to revolve on the internal gear ring. Under the transmission action of the bent rod, the sleeve rotates on the straight rod. At the same time, under the transmission action of the round rod, the scraper cleans and removes the welding slag on the welding table, thus cleaning the welding table and ensuring the welding environment.

[0019] Furthermore, the end of the induction coil on the optical rod near the sliding block is the current input terminal.

[0020] In order to increase the current to the electric valve at the nozzle as the sliding block rotates downward on the spiral plate, the pressure applied by the downward movement of the rotating plate in conjunction with the nozzle conduction will cause the water to be atomized and sprayed out from the nozzle, thereby reducing the temperature inside the protective cover and reducing the generation of spatter such as welding slag.

[0021] Furthermore, a blocking ring with a groove is provided on the side of the spiral plate near the straight rod, and the pull rope is slidably connected to the blocking ring.

[0022] To prevent the slider from detaching from the spiral plate while sliding, thus preventing subsequent actions from being executed.

[0023] Furthermore, the mounting box is equipped with a controller.

[0024] To facilitate staff control of the device while responding to emergencies, and to automate the device.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. This invention, after adjusting the welding torch to the designated welding position, ensures that the ring cylinder is parallel to the welding table. Due to the large amount of heat generated during welding, the memory spring rod expands and elongates. This expansion causes the memory spring rod to increase the clamping force between the ring cylinder and the welding table, ensuring a tight seal and preventing splashes from rolling out of the gaps. During the forward rotation of the guide fan blades controlled by the controller, the rotating cylinder moves downwards synchronously under magnetic force. Simultaneously, centrifugal force causes the sliding block to rotate along the spiral plate. Since the diameter of the spiral plate increases as it descends, the sliding block pulls the pull rope, thereby causing the conductive ring to slide along the smooth rod while simultaneously pulling... As the dynamic reset spring extends, the effective number of turns of the induction coil decreases, and the current gradually increases. This increases the current supplied to the electric valve at the nozzle. When the current reaches the set value, the electric valve opens. Meanwhile, as the rotating drum descends, it drives the turntable to rotate and slide downwards, squeezing the flexible cylinder and the telescopic spring. Under the pressure of the turntable, the water inside the flexible cylinder is atomized and sprayed out through the nozzle. When the guide fan blades rotate in the forward direction, the controller controls the electric valve of the water supply tank to close, generating air jets that quickly spray the mist towards the welding area. This rapidly cools the welding area inside the protective cover under the sealed condition, while reducing the generation of welding slag and other spatter.

[0027] 2. When the guide fan blades of this invention are controlled to rotate in the reverse direction by the controller, on the one hand, the controller controls the electric valve of the water tank to open, and the water inside the water tank is transported to the flexible cylinder through the conduit. At the same time, under the action of centrifugal force, the sliding block is driven to gradually slide upward along the spiral plate. At this time, under the action of the return spring's own restoring force, the conductive ring is pulled to the left. At this time, the current supplied to the electric valve at the nozzle decreases, and the nozzle closes and stops spraying. On the other hand, the guide fan blades drive the rotating cylinder to rotate in the reverse direction. At this time, the rotating cylinder drives the turntable to rotate upward. With the action of the extension spring's own restoring force, the turntable rotates upward, increasing the volume of the flexible cylinder for water storage. During the rotation of the guide fan blades, the driving gear rotates, so that the driven gear revolves on the internal gear ring. Under the transmission action of the bent rod, the sleeve rotates on the straight rod. At the same time, under the transmission action of the round rod, the scraper cleans and removes the welding slag on the welding table, thus cleaning the welding table and ensuring the welding environment.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example:Figures 1-9 As shown, the present invention provides a technical solution:

[0040] like Figure 1 , Figure 8 As shown, a welding device with splash protection function includes a mounting box 1, an adjustment unit 2, a welding unit 3, a protection unit 4, and a cleaning unit 5. The mounting box 1 is placed on a horizontal ground. The mounting box 1 is fixedly connected to the adjustment unit 2, the welding unit 3 is fixedly connected to the mounting box 1, the protection unit 4 is fixedly connected to the welding unit 3, and the protection unit 4 is fixedly connected to the cleaning unit 5. The protection unit 4 has the function of preventing splashes from spreading outward.

[0041] Mounting box 1 is used to install and fix adjustment unit 2, welding unit 3, and protection unit 4. Adjustment unit 2 is used to adjust the placement position of the workpiece, welding unit 3 is used to weld the workpiece, protection unit 4 is used to prevent spatter from splashing, and cleaning unit 5 is used to clean the welding slag. After the workpiece is placed on adjustment unit 2 and positioned in the predetermined position by adjustment unit 2, welding is carried out by welding unit 3 while protection unit 4 intercepts the spatter generated during welding to prevent welding slag from sticking to the unwelded workpiece, affecting the welding quality, and preventing spatter from causing injury to workers. Then, the welding slag is cleaned by cleaning unit 5.

[0042] like Figure 2 As shown, the adjustment unit 2 includes a mounting frame 21, a fixing plate 22, a conveying motor 23, a screw 24, and a welding table 25. The mounting frame 21 is fixedly installed inside the mounting box 1, the fixing plate 22 is fixedly installed on the mounting frame 21, the fixed end of the conveying motor 23 is fixedly installed on the fixing plate 22, the output end of the conveying motor 23 is fixedly connected to the screw 24, and the screw 24 is threadedly connected to the welding table 25.

[0043] After the workpiece is placed on the welding table 25, the controller starts the conveyor motor 23, which drives the screw 24 to rotate, so that the welding table 25 slides back and forth on the mounting frame 21. The welding table 25 is adjusted to move to the designated position to complete the preparation work before welding.

[0044] like Figure 3 As shown, the welding unit 3 includes a mounting plate 31, an electric telescopic rod 32, a connecting block 33, a long plate 34, and an output motor 35. The mounting plate 31 is fixedly installed on the inner surface of the mounting box 1 at the end away from the horizontal ground. The fixed end of the electric telescopic rod 32 is fixedly installed on the mounting plate 31. The telescopic end of the electric telescopic rod 32 is fixedly connected to the connecting block 33. The long plate 34 is fixedly installed on the mounting plate 31. The fixed end of the output motor 35 is fixedly installed on the long plate 34.

[0045] like Figure 4 , Figure 5 , Figure 7As shown, welding unit 3 also includes an electric telescopic rod 36, a connecting plate 37, an electric push rod 38, a straight rod 39, and a welding torch 310. The output end of the output motor 35 is fixedly connected to the fixed end of the electric telescopic rod 36. The fixed end of the electric telescopic rod 36 is slidably mounted on the long plate 34. The output end of the electric telescopic rod 36 is fixedly connected to the connecting plate 37. The fixed end of the electric push rod 38 is fixedly mounted on the connecting plate 37. The output end of the electric push rod 38 is fixedly connected to the straight rod 39. The welding torch 310 is fixedly mounted on the end of the straight rod 39. The connecting plate 37, which is away from the horizontal ground, is rotatably connected to the connecting block 33. The connecting plate 37, which is close to the horizontal ground, is fixedly connected to the protective unit 4.

[0046] After the workpiece is placed, the controller controls the electric telescopic rod 32 on the mounting plate 31 and the electric telescopic rod 36 on the long plate 34 to extend, driving the connecting block 33 to move downwards to the approximate welding position for coarse adjustment. This causes the connecting plate 37 and the electric push rod 38 to move downwards. At this time, the controller controls the electric push rod 38 to extend, driving the welding torch 310 on the straight rod 39 to continue moving downwards to the designated welding position for fine adjustment. The welding torch 310 then operates to weld the workpiece. During the continued welding process, the controller controls the output motor 35 to start, thereby driving the electric telescopic rod 36 to move left and right, changing the position of the welding torch 310, and achieving continuous welding of the workpiece.

[0047] like Figures 7-9 As shown, the protective unit 4 includes a protective cover 41, a spiral plate 42, a rotating drum 43, a turntable 44, a smooth rod 45, a return spring 46, and a conductive ring 47. The protective cover 41 is fixedly connected to the connecting plate 37 at the end near the horizontal ground. The spiral plate 42 is fixedly installed inside the protective cover 41. The rotating drum 43 is threadedly connected to the straight rod 39 and fixedly connected to the turntable 44. One end of the smooth rod 45 is rotatably connected to the rotating drum 43, and the other end is fixedly connected to one end of the return spring 46. The other end of the return spring 46 is fixedly connected to the conductive ring 47. The conductive ring 47 is slidably connected to the smooth rod 45. An induction coil is evenly wound on the smooth rod 45. The protective cover 41 is fixedly connected to the cleaning unit 5. The rotating drum 43 is made of magnet.

[0048] like Figures 5-9As shown, the protective unit 4 also includes a pull rope 48, a sliding block 49, a fixed plate 410, a flexible cylinder 411, a telescopic spring 412, a memory spring rod 413, and a ring cylinder 414. One end of the pull rope 48 is fixedly connected to the conductive ring 47, and the other end of the pull rope 48 is fixedly connected to the sliding block 49. The fixed plate 410 is fixedly installed on the straight rod 39. A nozzle is provided on the fixed plate 410, and an electric valve is provided at the nozzle. The conductive ring 47 is electrically connected to the electric valve. One end of the flexible cylinder 411 is fixedly connected to the turntable 44, and the other end is slidably connected to the fixed plate 410. One end of the telescopic spring 412 is fixedly connected to the turntable 43, and the other end is rotatably connected to the fixed plate 410. One end of the memory spring rod 413 is fixedly connected to the end of the protective cover 41 near the horizontal ground, and the other end is fixedly connected to the ring cylinder 414.

[0049] After adjusting the welding torch 310 to the designated welding position, the ring cylinder 414 is parallel to the welding table 25. Due to the large amount of heat generated during welding, the memory spring rod 413 expands and elongates. At this time, the memory spring rod 413 drives the ring cylinder 414 to increase the clamping force between it and the welding table 25, ensuring sealing and preventing splashes from rolling out of the gaps. During the forward rotation of the guide fan blade 51 controlled by the controller, the rotating cylinder 43 rotates synchronously and moves downward under the action of magnetic force. On the one hand, under the action of centrifugal force, the sliding block 49 rotates along the spiral plate 42. Since the diameter of the spiral plate 42 increases as it goes downward, the sliding block 49 pulls the pull rope 48, thereby causing the conductive ring 47 to slide along the smooth rod 45. Simultaneously, the return spring 46 is pulled to extend. As the effective number of turns of the induction coil decreases, the current gradually increases. At this time, the current supplied to the electric valve at the nozzle increases. When the current reaches the set value, the electric valve opens. On the other hand, as the rotating drum 43 rotates and descends, it drives the turntable 44 to rotate and slide downwards synchronously, squeezing the flexible cylinder 411 and the telescopic spring 412. Under the pressure of the turntable 44, the water inside the flexible cylinder 411 is atomized and sprayed out through the nozzle. When the guide fan blade 51 rotates in the forward direction, the controller controls the electric valve of the water supply tank 59 to close and generate air jets, which quickly spray the spray towards the welding point, rapidly cooling the welding point inside the protective cover 41 under the sealed state, and reducing the generation of welding slag and other spatter.

[0050] like Figures 4-8As shown, the cleaning unit 5 includes a guide fan blade 51, a drive gear 52, a driven gear 53, an internal gear ring 54, a round rod 55, a scraper 56, a bent rod 57, a sleeve 58, and a water tank 59. The guide fan blade 51 is fixedly mounted on the straight rod 39, the drive gear 52 is fixedly mounted on the straight rod 39, the driven gear 53 is meshed with the drive gear 52, the driven gear 53 is fixedly connected to the internal gear ring 54, the internal gear ring 54 is fixedly mounted inside the protective cover 41, and one end of the round rod 55 is fixedly connected to the scraper 56. One end of the rod is fixedly connected to the driven gear 53, and the other end of the bent rod 57 is fixedly connected to the driven gear 53. The other end is fixedly connected to the sleeve 58. The sleeve 58 is fitted onto the straight rod 39. One end of the water tank 59 is fixedly connected to the end of the protective cover 41 away from the horizontal ground. The other end of the water tank 59 is fixedly connected to the connecting plate 37. The guide fan blade 51 is made of magnet at the end near the rotating drum 43. The water tank 59 is equipped with an electric valve. The water tank 59 extends into the flexible cylinder 411 through a pipe.

[0051] When the controller controls the guide fan blade 51 to rotate in the reverse direction, on the one hand, the controller controls the electric valve of the water tank 59 to open, and the water inside the water tank 59 is transported to the flexible cylinder 411 through the conduit. At the same time, under the action of centrifugal force, the sliding block 49 is driven to gradually slide upward along the spiral plate 42. At this time, under the action of the self-restoring force of the return spring 46, the conductive ring 47 is pulled to the left. At this time, the current supplied to the electric valve at the nozzle decreases, and the nozzle closes and stops spraying. On the other hand, the guide fan blade 51 drives the rotating drum 43 to rotate in the reverse direction. At this time, the rotating drum... 43 drives the turntable 44 to rotate upwards. With the self-restoring force of the telescopic spring 412, the turntable 44 rotates upwards, increasing the volume of the flexible cylinder 411 for water storage. During the rotation of the guide fan blade 51, the drive gear 52 rotates, causing the driven gear 53 to revolve on the internal gear ring 54. Under the transmission action of the bent rod 57, the sleeve 58 rotates on the straight rod 39. At the same time, under the transmission action of the round rod 55, the scraper 56 cleans and removes the welding slag on the welding table 25, thus cleaning the welding table 25 and ensuring the welding environment.

[0052] like Figure 9 As shown, the end of the induction coil on the light rod 45 near the sliding block 49 is the current input terminal.

[0053] In order to increase the current to the electric valve at the nozzle during the downward rotation of the sliding block 49 on the spiral plate 42, the pressure applied by the downward movement of the rotating disc 44 in conjunction with the nozzle conduction is used to atomize and spray water from the nozzle, thereby reducing the temperature inside the protective cover 41 and reducing the generation of spatter such as welding slag.

[0054] like Figure 8 As shown, a blocking ring with a groove is provided on the spiral plate 42 near the straight rod 39, and the pull rope 48 is slidably connected to the blocking ring.

[0055] To prevent the slider 49 from detaching from the spiral plate 42 when sliding on the spiral plate 42, which would prevent subsequent actions from being performed.

[0056] like Figure 1 As shown, the mounting box 1 is equipped with a controller.

[0057] To facilitate staff control of the device while responding to emergencies, and to automate the device.

[0058] Working principle of the invention:

[0059] After the workpiece is placed on the welding table 25, the controller starts the conveyor motor 23, which drives the screw 24 to rotate, so that the welding table 25 slides back and forth on the mounting frame 21. The welding table 25 is adjusted to move to the designated position to complete the preparation work before welding.

[0060] After the workpiece is placed, the controller controls the electric telescopic rod 32 on the mounting plate 31 and the electric telescopic rod 36 on the long plate 34 to extend, driving the connecting block 33 to move downwards to the approximate welding position for coarse adjustment. This causes the connecting plate 37 and the electric push rod 38 to move downwards. At this time, the controller controls the electric push rod 38 to extend, driving the welding torch 310 on the straight rod 39 to continue moving downwards to the designated welding position for fine adjustment. The welding torch 310 then operates to weld the workpiece. During the continued welding process, the controller controls the output motor 35 to start, thereby driving the electric telescopic rod 36 to move left and right, changing the position of the welding torch 310, and achieving continuous welding of the workpiece.

[0061] After adjusting the welding torch 310 to the designated welding position, the ring cylinder 414 is parallel to the welding table 25. Due to the large amount of heat generated during welding, the memory spring rod 413 expands and elongates. At this time, the memory spring rod 413 drives the ring cylinder 414 to increase the clamping force between it and the welding table 25, ensuring sealing and preventing splashes from rolling out of the gaps. During the forward rotation of the guide fan blade 51 controlled by the controller, the rotating cylinder 43 rotates synchronously and moves downward under the action of magnetic force. On the one hand, under the action of centrifugal force, the sliding block 49 rotates along the spiral plate 42. Since the diameter of the spiral plate 42 increases as it goes downward, the sliding block 49 pulls the pull rope 48, thereby causing the conductive ring 47 to slide along the smooth rod 45. Simultaneously, the return spring 46 is pulled to extend. As the effective number of turns of the induction coil decreases, the current gradually increases. At this time, the current supplied to the electric valve at the nozzle increases. When the current reaches the set value, the electric valve opens. On the other hand, as the rotating drum 43 rotates and descends, it drives the turntable 44 to rotate and slide downwards synchronously, squeezing the flexible cylinder 411 and the telescopic spring 412. Under the pressure of the turntable 44, the water inside the flexible cylinder 411 is atomized and sprayed out through the nozzle. When the guide fan blade 51 rotates in the forward direction, the controller controls the electric valve of the water supply tank 59 to close and generate air jets, which quickly spray the spray towards the welding point, rapidly cooling the welding point inside the protective cover 41 under the sealed state, and reducing the generation of welding slag and other spatter.

[0062] When the controller controls the guide fan blade 51 to rotate in the reverse direction, on the one hand, the controller controls the electric valve of the water tank 59 to open, and the water inside the water tank 59 is transported to the flexible cylinder 411 through the conduit. At the same time, under the action of centrifugal force, the sliding block 49 is driven to gradually slide upward along the spiral plate 42. At this time, under the action of the self-restoring force of the return spring 46, the conductive ring 47 is pulled to the left. At this time, the current supplied to the electric valve at the nozzle decreases, and the nozzle closes and stops spraying. On the other hand, the guide fan blade 51 drives the rotating drum 43 to rotate in the reverse direction. At this time, the rotating drum... 43 drives the turntable 44 to rotate upwards. With the self-restoring force of the telescopic spring 412, the turntable 44 rotates upwards, increasing the volume of the flexible cylinder 411 for water storage. During the rotation of the guide fan blade 51, the drive gear 52 rotates, causing the driven gear 53 to revolve on the internal gear ring 54. Under the transmission action of the bent rod 57, the sleeve 58 rotates on the straight rod 39. At the same time, under the transmission action of the round rod 55, the scraper 56 cleans and removes the welding slag on the welding table 25, thus cleaning the welding table 25 and ensuring the welding environment.
