Description

Technical Field

[0001] This invention relates to the field of anti-skid chain welding technology, specifically to an anti-skid chain pressure welding device and method. Background Technology

[0002] Snow chains are strip-shaped metal chains made up of interlocking links. They are essential automotive safety equipment with anti-skid functions, typically used on snowy and muddy roads to protect tires, prevent them from slipping, and ensure normal vehicle operation. As a widely used device for enhancing vehicle tire safety, a key step in the manufacturing process of snow chains is the secure pressing and welding of the chain ends to ensure the chain's stability and durability under extreme conditions. Currently, traditional welding equipment for anti-skid chains typically uses pneumatic or hydraulic locking devices to firmly clamp the chain for welding. However, these devices struggle to guarantee absolute chain stability during the welding process. Because these locking devices often only provide localized or momentary pressure and cannot maintain chain stability over the long term, the tightening effect at the chain ends is unsatisfactory, leading to loosening after welding. This severely impacts the overall performance and reliability of the anti-skid chain. Furthermore, traditional welding equipment often suffers from uneven pressure distribution. This uneven pressure application can not only prevent the materials at the weld joint from fully fusing but also cause stress concentration at the weld interface, increasing the risk of cracks. In some cases, even if no obvious defects are apparent in the short term, long-term use can lead to gradual loosening due to stress accumulation, ultimately affecting the anti-skid chain's effectiveness and lifespan. Patent application CN119260136A discloses a pressure welding device and method for anti-skid chains. Through the cooperation of a clamping assembly and a pressure mechanism, the clamping plate drives the clamping part to fix the anti-skid chain to be welded. Simultaneously, the first locking block and the second locking block achieve a strong pressure fixing effect through the tight adsorption between the electromagnet ring and the locking iron plate, thereby enhancing the locking force on the anti-skid chain. This effectively prevents the anti-skid chain from loosening during the welding process, ensuring the strength of the weld joint and improving the overall quality of the anti-skid chain. Furthermore, by setting multiple sets of pressure mechanisms on the clamping part, symmetrically distributed... The first and second pressurizing components achieve a strong and uniform pressure on the anti-skid chain. This uniform pressure promotes good pressing of the chain ends, thus forming a good weld joint. However, before welding, the position of the connecting ring needs to be adjusted by a rotating clamp. When the rotating clamp rotates the connecting ring, it will relatively pull the subsequent connecting rings, affecting the welding of the subsequent connecting rings. Furthermore, it directly clamps both ends of the connecting ring, and the butt welding ends of the connecting ring are deformed by the pressure, affecting the accuracy of the butt joint and thus the quality of the weld. Therefore, we propose an anti-skid chain pressurized butt welding device and method to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide a pressure welding device and method for anti-skid chains to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a pressure welding device and method for anti-skid chains, comprising a base, a conveyor frame and a guide frame mounted on the top of the base, a mounting seat located between the conveyor frame and the guide frame on the top of the base, and a clamping mechanism for clamping the connecting ring of the anti-skid chain on the top of the mounting seat. The conveyor frame and guide frame are equipped with a defined conveying mechanism that can contact the connecting rings, and the connecting rings are in a continuous perpendicular state. The clamping mechanism can adaptively limit the vertically related connecting rings. The top of the mounting base is provided with an adjustable welding mechanism for limiting the welding of the connecting ring butt joint, and a drive mechanism for driving the clamping mechanism and the adjustable welding mechanism. The adjusting welding mechanism includes a positioning and welding assembly, which is movable and forms a closed loop to perform a wrapping welding on the connecting ring. The positioning and welding assembly includes a pre-defined frame, an air blowing nozzle, and a ring welding assembly. The annular welding assembly is located in the middle of the pre-limiting frame and directly opposite the welding point of the connecting ring. Both ends of the pre-limiting frame can contact the connecting ring and limit the mating end of the connecting ring. The air blowing nozzle is installed on the inner side of both ends of the pre-limiting frame and can blow air onto the welding point of the connecting ring before and after welding. The clamping mechanism clamps the connecting ring when the connecting ring is in a pre-limited state where the connecting ring is in a closed loop, and the annular welding assembly welds the connecting ring when the connecting ring is clamped by the clamping mechanism.

[0005] Preferably, a conveying groove is provided between the conveyor frame and the guide frame to define the vertical state of the connecting ring. The pre-defined frame has a through hole in the middle. The annular welding assembly passes through the through hole and is slidably connected to it. Two fan electrode plates for controlling the airflow of the blower head are installed on the inner side of the through hole. A conductive block that can connect the two fan electrode plates is installed on the part of the annular welding assembly that passes through the through hole. When the annular welding assembly is not in operation, the conductive block is in contact with the two fan electrode plates; when the annular welding assembly is in operation, the conductive block is disconnected from the two fan electrode plates. The end of the annular welding assembly is provided with a welding electrode plate that can contact and connect with the annular welding assembly.

The end of the annular welding assembly that passes through the through hole is mounted on the telescopic frame, and a second spring is connected between the telescopic frame and the pre-limiting frame. The second spring is used to drive the annular welding assembly and the pre-limiting frame to change their relative positions.

[0008] Preferably, the adjusting welding mechanism further includes a welding lifting assembly, which includes a lifting fixing frame, a lifting guide rail, a lifting drive shaft, and a fourth helical gear. The lifting fixing frame is installed on the top of the mounting base, the lifting guide rail is installed on the top of the lifting fixing frame, the lifting drive shaft is vertically rotatably connected to the middle of the lifting guide rail, and the bottom end of the lifting drive shaft passes through the lifting fixing frame and connects to the fourth helical gear. The lifting drive shaft has opposite threads at both ends and is threadedly connected to the positioning frame, which is slidably connected to the lifting guide rail.

[0009] Preferably, the mounting base includes a base plate, a first side plate, and a second side plate. The base plate is installed on the top of the machine base, the first side plate is installed on two opposite sides of the top of the base plate, and the second side plate is installed on the other two opposite sides of the top of the base plate.

[0010] Preferably, the drive mechanism includes a guide slide rod, a first helical gear, a second helical gear, a transmission shaft, a third helical gear, a second motor, and a clamping guide post. Clamping guide posts are respectively installed at both ends of the inner side of the first side plate, and guide slide rods are rotatably connected to the middle of the inner side of the first side plate. A first helical gear is installed at the inner end of each guide slide rod. A second motor is installed in the middle of the outer side of one of the second side plates. The output shaft of the second motor is connected to a transmission shaft rotatably connected to the second side plate. A second helical gear and a third helical gear are respectively installed on the outer sides of both ends of the transmission shaft. The second helical gear meshes with the first helical gear, and the third helical gear meshes with the fourth helical gear.

[0011] Preferably, the clamping mechanism includes a lifting base, a telescopic rod, a first electric push rod, a limiting frame, a slide, a horizontal clamping plate, a limiting guide post, a vertical clamping plate, and a first spring. The slide block is slidably connected to the upper clamping guide post, and the middle of the slide block is threadedly connected to the guide slide rod, allowing the slide block to move relative to the guide rod. The limiting guide posts are respectively installed at both ends of the top of the slide block. The lifting base is slidably connected to the limiting guide posts, and a first electric push rod is installed on the top of the lifting base. The output end of the first electric push rod is connected to the top of the limiting guide posts inside the lifting base. The bottom of the lifting base is slidably connected to a horizontal clamping plate and a vertical clamping plate that can move into the lifting base. The vertical clamping plate is located in the middle of the horizontal clamping plate, and the bottom ends of the horizontal and vertical clamping plates can be inserted into the top of the slide block. The tops of the horizontal and vertical clamping plates extend into the interior of the lifting base and are equipped with a first spring, the top of which is mounted on the lifting base. Both ends of the top of the first side plate are equipped with self-extending telescopic rods. The top of the telescopic rods is installed at the bottom of the limiting frame, and the lifting base is slidably connected to the limiting frame.

[0012] Preferably, the defined conveying mechanism includes a positioning ball, a conveying positioning roller, a first motor, a transmission toothed belt, and a spur gear. Both the conveyor frame and the guide frame are rotatably connected to conveyor positioning rollers on their inner sides. These rollers can contact the top of the transverse connecting ring, and a positioning ball that can rotate freely on the inner end of each roller can contact the outer side of the vertical connecting ring. The outer end of the conveying positioning roller extends into the conveying frame or guide frame and is mounted on a spur gear. The outer side of the spur gear meshes with a transmission toothed belt. A first motor is mounted on the outer side of the conveying frame, and the output shaft of the first motor is connected to one of the spur gears.

[0013] Preferably, the steps include: Step 1: Place the connecting rings on the anti-skid chain vertically on the conveyor frame, with the vertical connection inside the conveyor trough and the anti-skid chain in a stretched state. At this time, the conveyor positioning roller contacts the top of the horizontal connecting ring, and the positioning ball contacts the outer side of the vertical connecting ring. Then, under the conveying of the rotating conveyor positioning roller, the connecting ring can move gradually and stably. Step 2: When the connecting ring moves to the top of the mounting base, the drive mechanism drives the welding lifting assembly to move up and down. The welding telescopic assembly drives the positioning welding assembly, and the pre-limited frames first contact each other and form a ring to contact the connecting ring. At this time, the conductive block connects the fan electrode plate, so that the fan assembly can send air into the ventilation cavity a, and then blow it out from the air blower to clean the welding joint of the connecting ring. Step 3: Driven by the output end of the first electric push rod, the lifting base moves downward, causing the horizontal clamping plate and the vertical clamping plate to move downward. When clamping the horizontal connecting ring, the bottom of the vertical clamping plate abuts against the vertical connecting ring, while the bottom of the horizontal clamping plate inserts into the top of the slide. Then, driven by the movement of the lifting base, the horizontal clamping plate can squeeze and clamp the horizontal connecting ring from the end. When clamping the vertical connecting ring, the bottom of the horizontal clamping plate abuts against the horizontal connecting ring, while the bottom of the vertical clamping plate inserts into the top of the slide. Then, driven by the movement of the lifting base, the vertical clamping plate can squeeze and clamp the vertical connecting ring from the end. Step 4: Then, under the continued drive of the drive mechanism, the ring welding assembly can continue to move down and come into contact with each other. At this time, the welding electrode plates come into contact with each other, and the ring welding assembly is turned on, so that the ring welding assembly can weld the connecting ring. At this time, the conductive block and the fan electrode plate are in a disengaged state, and the blower nozzle stops blowing air on the weld joint. Step 5: After the welding is completed, the annular welding assembly detaches first, then the clamping mechanism releases its grip on the connecting ring, and finally the pre-limiting frame releases its restraint on the connecting ring. When the annular welding assembly detaches and the pre-limiting frame closes, the air blower blows air onto the weld joint of the connecting ring to cool it down and remove debris.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This anti-skid chain pressure welding equipment, driven by a drive mechanism, allows a pre-limiting frame to first limit the welding end of the connecting ring. Then, the clamping mechanism, driven by the drive mechanism, clamps the connecting ring. Due to the limitation by the pre-limiting frame, the clamping mechanism that subsequently clamps the connecting ring can reduce the displacement of the welding end of the connecting ring under the action of force when applying force, thereby making the docking of the connecting ring joint more precise and resulting in a better welding effect.

[0015] 2. This anti-skid chain pressure welding equipment, through a limited conveying mechanism, can limit and convey the connecting rings in a continuous perpendicular state, so that the connecting rings can be welded in this state without having to clamp and change their position again before welding. This effectively avoids the possibility of subsequent positional changes of the connecting rings, which could affect the welding accuracy. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0020] Example: Figure 1-14 As shown, the present invention provides a pressure welding device and method for anti-skid chains, including a base 1. A conveyor frame 201 and a guide frame 202 are mounted on the top of the base 1. A mounting seat 5 is mounted on the top of the base 1 between the conveyor frame 201 and the guide frame 202. The top of the mounting seat 5 is provided with a clamping mechanism 4 for clamping the connecting ring of the anti-skid chain. By clamping the connecting ring with the clamping mechanism 4, the connecting ring can be clamped, thereby enabling the connecting ring to be stably welded. The conveyor frame 201 and guide frame 202 are equipped with a limiting conveying mechanism 3 that can contact the connecting rings. The connecting rings are in a continuous perpendicular state. The clamping mechanism 4 can adaptively limit the vertically related connecting rings. The top of the mounting base 5 is provided with an adjustable welding mechanism 7 for limiting the welding of the connecting ring butt joint, and a drive mechanism 6 for driving the clamping mechanism 4 and the adjustable welding mechanism 7. The adjusting welding mechanism 7 includes a positioning and welding assembly, which is movable and forms a closed loop to perform wrapping welding on the connecting ring. The positioning and welding assembly includes a pre-limiting frame 721, an air blowing nozzle 723, and a ring welding assembly 724. The annular welding assembly 724 is located in the middle of the pre-limiting frame 721 and directly opposite the welding point of the connecting ring. Both ends of the pre-limiting frame 721 can contact the connecting ring and limit the mating end of the connecting ring. The air blowing nozzle 723 is installed on the inner side of both ends of the pre-limiting frame 721 and can blow air onto the welding point of the connecting ring before and after welding. When the clamping mechanism 4 is in the state where the connecting ring is limited by the pre-limiting frame 721 forming a closed loop, it clamps the connecting ring; when the annular welding assembly 724 is in the state where the connecting ring is clamped by the clamping mechanism 4, it welds the connecting ring. It should be noted that adjacent connecting rings are perpendicular to each other and interlocked, with their inner sides abutting each other. This means the connecting rings are in a normal stretched state. The limiting conveying mechanism 3 can limit this state of the connecting rings and convey them accordingly. Connecting rings conveyed and welded in this state do not require further clamping and repositioning before welding, effectively preventing potential positional changes that could affect welding accuracy. Driven by the driving mechanism 6, the pre-limiting frame 721 first limits the welding end of the connecting ring, and then the clamping mechanism 4, driven by the driving mechanism 6, clamps the connecting ring. Because of the limitation by the pre-limiting frame 721, the clamping mechanism 4, when applying force, can reduce the force on the welding end of the connecting ring. The action causes a shift, making the butt joint of the connecting ring more precise, thus improving the welding effect of the connecting ring. After the clamping mechanism 4 clamps the connecting ring, the annular welding assembly 724 can weld the connecting ring at the butt joint in an annular shape. Through the annular welding assembly 724, the welding of the connecting ring at the butt joint can be relatively uniform, thus improving the welding effect. The air blower 723 can clean the connecting ring before welding, avoiding impurities on the connecting ring that may affect the welding precision. The air blower 723 can also clean and cool the connecting ring after welding, allowing the weld to cool down quickly and blow away welding residue. Its wrap-around welding is a multi-point simultaneous welding in an annular shape. The annular welding assembly 724 is equipped with multiple welding heads, which can weld the connecting ring at the same time.

[0021] Furthermore, a conveying groove is provided between the conveyor frame 201 and the guide frame 202 to limit the vertical state of the connecting ring. The pre-limiting frame 721 has a through hole in the middle. The annular welding assembly 724 passes through the through hole and is slidably connected to it. Two fan electrode plates 728 for controlling the air blowing of the air blower head 723 are installed on the inner side of the through hole. The part of the annular welding assembly 724 passing through the through hole is equipped with a conductive block 727 that can connect the two fan electrode plates 728. When the annular welding assembly 724 is not welding, the conductive block 727 is in contact with the two fan electrode plates 728. When the annular welding assembly 724 is welding, the conductive block 727 is disengaged from the two fan electrode plates 728. The end of the annular welding assembly 724 is provided with a welding electrode plate 726 that can contact and connect with the annular welding assembly 724. It should be noted that the limiting of the conveying groove allows the vertical connecting ring to move stably in a vertical position. Through the through hole, the annular welding assembly 724 can move relative to the pre-limiting frame 721. When it contacts the pre-limiting frame 721, the annular welding assembly 724 can continue to move before welding the connecting ring. When the annular welding assembly 724 is not connected, the conductive block 727 contacts the two fan electrode plates 728 to make electrical connection. At this time, the blower nozzle 723 can blow air onto the connecting ring. When the annular welding assembly 724 is connected, the conductive block 727 is disengaged from the two fan electrode plates 728, thus directly realizing the effect of starting and stopping the blower nozzle 723, making it more intelligent. The annular welding assembly 724 is only electrically connected when the welding electrode plates 726 are in contact, effectively avoiding the risk of premature connection of the annular welding assembly 724.

[0022] Specifically, ventilation chambers 721a are provided on the inner sides of both ends of the pre-limited frame 721, and the air blowing head 723 is connected to the ventilation chambers 721a. The pre-limiting frame 721 has air inlets on the outer sides at both ends, and the air inlets are connected to the ventilation cavity 721a. A fan assembly 725 is installed inside the air inlet. When the conductive block 727 is in contact with the two fan electrode plates 728, the fan assembly 725 is electrically connected. It should be noted that the air is delivered through the ventilation cavity 721a, which in turn delivers the air to the blower nozzle 723 and finally discharges it through the blower nozzle 723. The conductive block 727 connects the two fan electrode plates 728, which enables the fan assembly 725 to operate, thereby allowing the fan assembly 725 to deliver air into the ventilation cavity 721a.

[0023] The adjusting welding mechanism 7 also includes a butt welding telescopic assembly, which includes a telescopic frame 711, a positioning frame 712, and a second electric push rod 713. The telescopic frame 711 is slidably connected to one end of the positioning frame 712, and the second electric push rod 713 is installed at the other end of the positioning frame 712. The output end of the second electric push rod 713 is connected to the telescopic frame 711 inside the positioning frame 712. The end of the annular welding assembly 724 passing through the through hole is mounted on the telescopic frame 711, and a second spring 722 is connected between the telescopic frame 711 and the pre-limiting frame 721. The second spring 722 is used to drive the relative position of the annular welding assembly 724 and the pre-limiting frame 721 to change. It should be noted that, driven by the output end of the second electric push rod 713, the telescopic frame 711 can extend and retract relative to the positioning frame 712. Under the action of the positioning frame 712 rising and falling, the telescopic frame 711 can also rise and fall together, thereby driving the annular welding assembly 724 to move, and also driving the pre-limiting frame 721 to move. After the pre-limiting frame 721 comes into contact with the positioning frame 722, the pre-limiting frame 721 is relatively stationary. At this time, the annular welding assembly 724 can move, and the pre-limiting frame 721 moves relative to the annular welding assembly 724.

[0024] The adjusting welding mechanism 7 also includes a welding lifting assembly, which includes a lifting fixing frame 701, a lifting guide rail 702, a lifting drive shaft 703, and a fourth helical gear 704. The lifting fixing frame 701 is mounted on the top of the mounting base 5, the lifting guide rail 702 is mounted on the top of the lifting fixing frame 701, the lifting drive shaft 703 is vertically rotatably connected to the middle of the lifting guide rail 702, and the bottom end of the lifting drive shaft 703 passes through the lifting fixing frame 701 and is connected to the fourth helical gear 704. The lifting drive shaft 703 has opposite threads at both ends, and is threadedly connected to the positioning frame 712 respectively. The positioning frame 712 is slidably connected to the lifting guide rail 702. It should be noted that the lifting drive shaft 703 can rotate stationary relative to the lifting guide rail 702, and under the action of the rotation of the fourth helical gear 704, the lifting drive shaft 703 can rotate, and under the drive of the rotation of the lifting drive shaft 703, the positioning frame 712 can move relative to it.

[0025] The mounting base 5 includes a base plate 501, a first side plate 502, and a second side plate 503. The base plate 501 is installed on the top of the base 1, the first side plate 502 is installed on two opposite sides of the top of the base plate 501, and the second side plate 503 is installed on the other two opposite sides of the top of the base plate 501.

[0026] The drive mechanism 6 includes a guide slide 601, a first helical gear 602, a second helical gear 603, a transmission shaft 604, a third helical gear 605, a second motor 606, and a clamping guide post 607. Clamping guide posts 607 are respectively installed at both ends of the inner side of the first side plate 502, and guide slide rods 601 are rotatably connected to the middle of the inner side of the first side plate 502. A first helical gear 602 is installed at the inner end of each guide slide rod 601. A second motor 606 is installed in the middle of the outer side of one of the second side plates 503. The output shaft of the second motor 606 is connected to a transmission shaft 604 rotatably connected to the second side plate 503. A second helical gear 603 and a third helical gear 605 are respectively installed on the outer sides of both ends of the transmission shaft 604. The second helical gear 603 meshes with the first helical gear 602, and the third helical gear 605 meshes with the fourth helical gear 704. It should be noted that the guide slide 601 can rotate relatively stationary on the first side plate 502. Driven by the output shaft of the second motor 606, the transmission shaft 604 can rotate. Driven by the transmission shaft 604, the first helical gear 602 and the transmission shaft 604 can rotate. Driven by the first helical gear 602, the guide slide 601 can rotate. Driven by the third helical gear 605, the fourth helical gear 704 can rotate.

[0027] The clamping mechanism 4 includes a lifting base 401, a telescopic rod 402, a first electric push rod 403, a limiting frame 404, a slide block 405, a horizontal clamping plate 406, a limiting guide post 407, a vertical clamping plate 408, and a first spring 409. The slide block 405 is slidably connected to the clamping guide post 607, and the middle of the slide block 405 is threadedly connected to the guide slide rod 601, allowing the slide block 405 to move relative to it. The limiting guide posts 407 are respectively installed at both ends of the top of the slide block 405. The lifting base 401 is slidably connected to the limiting guide posts 407, and a first electric push rod 403 is installed on the top of the lifting base 401. The output end of the first electric push rod 403 is connected to the top end of the limiting guide posts 407 inside the lifting base 401. The bottom of the lifting base 401 is slidably connected to a horizontal clamping plate 406 and a vertical clamping plate 408 that can move into the lifting base 401. The vertical clamping plate 408 is located in the middle of the horizontal clamping plate 406, and the bottom ends of the horizontal clamping plate 406 and the vertical clamping plate 408 can be inserted into the top of the slide block 405. The tops of the horizontal clamping plate 406 and the vertical clamping plate 408 extend into the interior of the lifting base 401 and are equipped with a first spring 409, the top of which is mounted on the lifting base 401. Both ends of the top of the first side plate 502 are equipped with self-extending telescopic rods 402. The top ends of the telescopic rods 402 are installed at the bottom of the limiting frame 404, and the lifting base 401 is slidably connected to the limiting frame 404. It should be noted that, driven by the guide slide rod 601, the slide block 405 can move relative to the connecting ring, achieving the effect of clamping it. Driven by the slide block 405, the limiting guide post 407 can move laterally. Driven by the output end of the first electric push rod 403, the lifting base 401 can move relative to the limiting guide post 407, thus achieving the lifting effect of the lifting base 401. The bottom ends of the horizontal clamping plate 406 and the vertical clamping plate 408 can be inserted into the slide block 405, making the horizontal clamping plate 406 and the vertical clamping plate 408 more stable when contacting and clamping the connecting ring. It should also be noted that when clamping the horizontal connecting ring, the bottom of the vertical clamping plate 408 abuts against the vertical connecting ring, while the bottom of the horizontal clamping plate 406 is inserted into the top of the slide 405. Then, driven by the movement of the lifting base 401, the horizontal clamping plate 406 can squeeze and clamp the horizontal connecting ring from the end. When clamping the vertical connecting ring, the bottom of the horizontal clamping plate 406 abuts against the horizontal connecting ring, while the bottom of the vertical clamping plate 408 is inserted into the top of the slide 405. Then, driven by the movement of the lifting base 401, the vertical clamping plate 408 can squeeze and clamp the vertical connecting ring from the end. Under the action of the first spring 409, the adaptive clamping effect of the horizontal clamping plate 406 and the vertical clamping plate 408 is achieved.

[0028] The defined conveying mechanism 3 includes a positioning ball 301, a conveying positioning roller 302, a first motor 303, a transmission toothed belt 304, and a spur gear 305. Both the conveyor frame 201 and the guide frame 202 are rotatably connected to conveying positioning rollers 302. The conveying positioning rollers 302 can contact the top of the transverse connecting ring, and a positioning ball 301 that can rotate freely on the conveying positioning roller 302 is provided at the inner end of the conveying positioning roller 302. The positioning ball 301 can contact the outer side of the vertical connecting ring. The outer end of the conveying positioning roller 302 extends into the conveying frame 201 or guide frame 202 and is mounted on the spur gear 305. The outer side of the spur gear 305 meshes with the transmission toothed belt 304. A first motor 303 is mounted on the outer side of the conveying frame 201. The output shaft of the first motor 303 is connected to one of the spur gears 305. It should be noted that the conveying positioning roller 302 can rotate relatively stationary, and under the action of the rotation of the conveying positioning roller 302, the connecting ring can be conveyed. More than half of the positioning ball 301 is inside the conveying positioning roller 302, that is, at this time the positioning ball 301 can rotate freely on the conveying positioning roller 302, and through the rotation of the positioning ball 301, the vertical connecting ring is conveyed and constrained. Driven by the rotation of the first motor 303, the spur gear 305 can rotate, and under the transmission of the transmission belt 304, the spur gear 305 can rotate, thereby driving the conveying positioning roller 302 to rotate.

[0029] Includes the following steps: Step 1: Place the connecting rings on the anti-skid chain vertically on the conveyor frame 201. The vertical connection is in the conveying groove and the anti-skid chain is in a stretched state. At this time, the conveying positioning roller 302 contacts the top of the horizontal connecting ring and the positioning ball 301 contacts the outer side of the vertical connecting ring. Then, under the conveying of the rotating conveying positioning roller 302, the connecting ring can move gradually and stably. Step 2: When the connecting ring moves to the top of the mounting base 5, the drive mechanism 6 drives the welding lifting assembly to rise and fall. Its welding telescopic assembly drives the positioning welding assembly, and its pre-limiting frame 721 first contacts each other and forms a ring to contact the connecting ring. At this time, the conductive block 727 connects the fan electrode plate 728, so that the fan assembly 725 can send air into the ventilation cavity 721a, and then blow it out from the air blower 723 to clean the welding joint of the connecting ring. Step 3: Driven by the output end of the first electric push rod 403, the lifting base 401 moves downward, causing the horizontal clamping plate 406 and the vertical clamping plate 408 to move downward. When clamping the horizontal connecting ring, the bottom of the vertical clamping plate 408 abuts against the vertical connecting ring, while the bottom of the horizontal clamping plate 406 inserts into the top of the slide block 405. Then, driven by the movement of the lifting base 401, the horizontal clamping plate 406 can squeeze and clamp the horizontal connecting ring from the end of the horizontal connecting ring. When clamping the vertical connecting ring, the bottom of the horizontal clamping plate 406 abuts against the horizontal connecting ring, while the bottom of the vertical clamping plate 408 inserts into the top of the slide block 405. Then, driven by the movement of the lifting base 401, the vertical clamping plate 408 can squeeze and clamp the vertical connecting ring from the end of the vertical connecting ring. Step 4: Then, under the continued drive of the drive mechanism 6, the annular welding assembly 724 can continue to move down and come into contact with each other. At this time, the welding electrode 726 comes into contact with each other, and the annular welding assembly 724 is turned on, so that the annular welding assembly 724 can weld the connecting ring. At this time, the conductive block 727 and the fan electrode 728 are in a disengaged state, and the air blower 723 stops blowing air on the weld joint. Step 5: After the welding is completed, the annular welding assembly 724 is released first, then the clamping mechanism 4 releases its clamp on the connecting ring, and finally the pre-limiting frame 721 releases its limit on the connecting ring. When the annular welding assembly 724 is released and the pre-limiting frame 721 is closed, the air blower 723 blows air onto the weld joint of the connecting ring to cool it down and remove debris.
