Description

Technical Field

[0001] The invention relates to the technical field of automobile parts manufacturing, and in particular to a forming and welding device for automobile parts. Background Art

[0002] Traditional automobile parts forming welding equipment has many shortcomings in tooling and unloading structure. On the one hand, the positioning efficiency and accuracy of parts are low during loading, and manual repeated measurement and adjustment are often required, which wastes time and is prone to errors, affecting welding quality and production efficiency. On the other hand, the unloading process usually relies on manual operation, with low automation and high labor intensity. In addition, during the manual unloading process, secondary damage may be caused to the welded parts due to improper operation, and there are also certain safety risks, such as burns and smashing. In addition, the connection of the entire welding and unloading process is not smooth, resulting in discontinuous production processes and reducing overall production efficiency. At the same time, traditional automobile parts forming welding equipment often has problems such as easy damage to parts, poor adaptability to parts of different shapes, and unstable fixation leading to poor welding quality in terms of parts fixing and buffering. For example, some equipment adopts a rigid fixing method. When clamping parts, due to the lack of buffering measures, it is easy to cause deformation, cracks and other damage to the surface of the parts due to excessive instantaneous pressure, affecting the performance of the parts. Moreover, the clamping device of traditional equipment usually has a fixed structure, which is difficult to flexibly adjust according to parts of different shapes, limiting the application range of the equipment. In addition, due to inaccurate fixation, parts may undergo slight displacement during the welding process, resulting in weld deviation and reduced welding quality. Summary of the invention

[0003] The present invention relates to a welding device for forming automobile parts. In terms of positioning and fixing parts, the cylinder drives the welding head to move vertically accurately, and cooperates with the "冂"-shaped vertical moving rail frame to provide a precise sliding track for the slide seat, thereby ensuring the accuracy of the welding position and shortening the welding cycle. At the same time, the design of the buffer seat and the clamping seat is very clever. The buffer spring can absorb the impact force during clamping to avoid damage to the parts, ensure uniform clamping force, and make the parts stable during welding; the clamping seat can adjust the deflection angle according to the shape of the parts, and combined with the height-adjustable pad column, it improves the adaptability to parts of different shapes, ensures that the parts do not move during welding, and further improves the welding quality.

[0004] The present invention provides a welding device for forming automobile parts, specifically comprising: a welding table; a frame is vertically upwardly provided on the back of the welding table, a welding machine and a controller are provided on the upper end of the frame, an inverted cylinder is also provided on the frame, and the end of the piston rod of the cylinder carries a welding head connected to the welding machine; a "冂"-shaped vertical moving rail frame is provided on the frame below the cylinder, and a slide seat connected to the end of the piston rod of the cylinder is vertically slidably installed on the vertical moving rail frame; a smoking box for sucking welding smoke is provided on the outer wall of the slide seat; the lower end of the slide seat is vertically fixedly connected with a horizontal "匚"-shaped connecting plate through a downwardly extending hanging plate; a buffer connecting seat is provided at a lower position in the middle of the connecting plate, and a clamping seat for squeezing and fixing parts is provided at the lower end of the buffer connecting seat;

[0005] The upper end of the welding table is provided with a tooling tray for placing automobile parts, the end of the tooling tray away from the frame is rotatably connected to the welding table, and the end of the welding table away from the frame is provided with a unloading cooling table connected to the tooling tray, and the tooling tray can be rotated upward to unload the automobile parts thereon to the unloading cooling table.

[0006] Optionally, a limit switch is provided at the bottom of the top frame of the vertical rail frame. When the slide seat moves up to the extreme position, the limit switch is triggered by extrusion, and the welding machine, cylinder and smoking box are interlocked and stop working.

[0007] Optionally, the back of the hanging plate is always tangent to the vertical rail of the vertical rail frame.

[0008] Optionally, two hook arms are provided vertically downward at the positions of the cantilevers at the left and right ends of the connecting plate near the ends, the hook arms at the endmost are longer than the hook arms on the inner side, the ends of the hook arms are provided with barbs, the size of the barbs of the hook arms at the endmost are larger than the barbs on the inner hook arms, and the hook arms slide downward along the side walls of the tooling disk.

[0009] Optionally, a smoke exhaust pipe for exhausting purified smoke is provided on one side of the smoking box, a smoke exhaust fan is built in the smoke exhaust pipe, and an external thread for connecting an external smoke removal pipe is also provided on the outer wall of the smoke exhaust pipe.

[0010] Optionally, the buffer seat is an inverted "L" shaped structure, and two buffer rods are vertically symmetrically provided at the upper end of the buffer seat, the buffer rods are vertically slidingly connected to the connecting plate, and the buffer rods are provided with buffer springs that always push the buffer seat downward. At least two lifting holes are vertically arranged at the middle lower end of the buffer seat, and the lifting holes are used to install the clamping seat. Under the natural action of the buffer spring, the lower end of the clamping seat is lower than the lower end of the welding head.

[0011] Optionally, an inner card slot for accommodating the lower end of the buffer connecting seat is opened upward at the upper end of the clamping seat. The middle part of the upper end of the clamping seat is installed in the hoisting hole through a hoisting bolt. The clamping seat can deflect slightly with the hoisting bolt as the rotation axis and use the two ends and corners at the bottom of the buffer connecting seat as the deflection limit stops. The hoisting bolts are installed in hoisting holes with different heights, and the deflectable angle of the clamping seat changes accordingly to clamp parts with different shapes. A smoking head is provided at the bottom of the clamping seat and penetrates through to the side where the welding head is located. The other end of the smoking head is fixedly connected to a pretreatment box through a metal connecting pipe. The pretreatment box is filled with flue gas filtering materials. A lifting hose is provided at the upper end of the pretreatment box and is connected to the smoking box for exhausting flue gas. Pad columns with adjustable height up and down are symmetrically screwed on the left and right sides of the bottom of the clamping seat. The pad columns clamp and fix the automotive parts on the tooling plate. The air cylinder pushes the sliding seat downward, and the welding head moves downward for welding. The connecting plate, buffer connecting seat, and clamping seat parts move downward accordingly. The clamping seat first contacts the metal part and squeezes and clamps it, and then the welding head performs welding.

[0012] Optionally, positioning columns are provided on the top plane of the tooling plate according to the shape of the automotive parts. A "π"-shaped ejecting member is also provided in the top plane of the tooling plate. One end of the ejecting member close to the unloading and cooling table is connected by a rotating shaft. The other end long side of the ejecting member extends to the outer side wall at the other end of the tooling plate. A reset elastic cord is connected between the long side of the ejecting member and the tooling plate. The reset elastic cord is used to limit the opening and closing angle between the ejecting member and the tooling plate and provide the reset ability for the ejecting member. Hanging lock members are provided at the positions corresponding to the short hook arms on the left and right side walls of the tooling plate. Hanging lock members are also provided at both ends of the long side of the ejecting member. The hanging lock members here are vertically corresponding to the long hook arms. A hanging lock column is horizontally slidably installed in each of the hanging lock members toward the side of the machine frame. The end of the hanging lock column is a semi-cylindrical head structure. A hanging lock spring that always pushes the head structure toward the side of the machine frame is sleeved on the hanging lock column. The lengths of the hanging lock columns and hanging lock springs on the ejecting member are greater than those of the hanging lock columns and hanging lock springs on the tooling plate. When the connecting plate moves downward, the hook arm moves downward, and the barb squeezes the hanging lock column and continues to move downward until the welding head welds the automotive parts. After welding and resetting, the connecting plate moves upward. The barb of the short hook arm first contacts the head of the hanging lock column on the tooling plate and drives the tooling plate to turn up. Then the barb of the long hook arm contacts the head of the hanging lock column on the ejecting member and drives the ejecting member to turn out from the tooling plate, pushing the automotive parts on the tooling plate out of the positioning columns and sliding down to the unloading and cooling table by their own gravity. The connecting plate continues to move upward, the barb disengages from the head of the hanging lock column, and both the tooling plate and the ejecting member are reset.

[0013] The present invention provides a forming and welding device for automotive parts, which has the following beneficial effects:

[0014] 1. In terms of welding power and control structure, the welding machine and controller installed on the top of the frame are the core. The welding machine can output stable current, voltage and other parameters that are suitable for different welding process requirements. This feature ensures the reliability of welding quality when facing the welding needs of various automotive parts. The controller accurately controls the action sequence and operating status of each component of the equipment based on preset programs and real-time feedback signals. Unlike traditional equipment that relies on manual experience, this equipment realizes automated operation, greatly improves production efficiency and stability, and effectively reduces errors that may be caused by manual intervention.

[0015] 2. In terms of welding execution and positioning structure, the inverted cylinder works in conjunction with the "冂"-shaped vertical rail frame. The piston rod of the cylinder drives the vertical displacement of the welding head. The power output is stable and the response is fast. Compared with other driving methods, it can complete the positioning of the welding head in a short time, effectively shortening the welding cycle. The vertical rail frame provides a precise vertical sliding track for the slide. The slide is connected to the end of the cylinder piston rod, which enhances the structural stability, makes the slide move more smoothly, and further ensures the positioning accuracy of the welding head. The design that the back of the hanging plate is always tangent to the vertical rail of the vertical rail frame optimizes the movement trajectory of the slide, reduces running shaking and deviation, and ensures accurate welding operations.

[0016] 3. In the component fixing and buffering structure, the "匚"-shaped connecting plate connected to the lower end of the slide seat through the hanging plate provides an installation foundation for the buffer connecting seat and the clamping seat. The buffer connecting seat adopts an inverted "L"-shaped structure, and the buffer rod at the upper end is vertically slidably connected to the connecting plate, and a buffer spring is installed on the buffer rod. When the clamping seat contacts the component to be welded, the buffer spring absorbs part of the impact force to avoid damage to the component due to excessive instantaneous pressure, while ensuring uniform clamping force, making the component more stable during the welding process. The clamping seat is installed in the lifting holes of different heights of the buffer connecting seat through lifting bolts. The deflection angle can be adjusted according to the shape of the component, which greatly improves the adaptability of the equipment to components of different shapes and expands the application range of the equipment. The upper and lower height-adjustable pads that are symmetrically screwed at the bottom of the clamping seat can accurately clamp and fix the automotive parts on the tooling plate to ensure that the parts will not be displaced during welding and ensure the welding quality.

[0017] 4. In terms of the welding smoke treatment structure, the smoke box and the matching smoke exhaust pipe on the outer wall of the slide are cleverly designed. The smoke exhaust pipe has a built-in smoke exhaust fan, and the strong suction force quickly sucks the welding smoke into the smoke box. The external thread on the outer wall of the smoke exhaust pipe is convenient for connection with the external professional smoke removal pipeline, further enhancing the welding smoke treatment capacity. At the same time, the smoke head at the bottom of the clamping seat is connected to the pretreatment box filled with smoke filter material through a metal connecting pipe. After preliminary filtration, it is sent to the smoke box through a lifting hose for further purification. This series of structures effectively improves the working environment, protects the health of operators, meets environmental protection requirements, reduces pollution to the surrounding environment, and is a major improvement on the traditional welding equipment that ignores the hazards of welding smoke.

[0018] 5. In terms of the tooling and unloading structure, the tooling plate at the upper end of the welding table has positioning columns on its top plane according to the shape of the parts, which can quickly and accurately position the parts, improving the feeding efficiency and positioning accuracy. One end of the tooling plate away from the machine frame is rotatably connected to the welding table, and in cooperation with the unloading and cooling table, it realizes the automatic unloading and cooling of the parts after welding. Especially in the second embodiment, the hanging lock parts, hanging lock columns, and hanging lock springs provided on the tooling plate and the ejecting parts cooperate with the hook pulling arms on the connecting plate to achieve the automatic connection during the welding and unloading processes. After welding is completed, the connecting plate moves upward. The barb of the short hook pulling arm first drives the tooling plate to turn up, and then the barb of the long hook pulling arm drives the ejecting part to turn up, pushing the part out of the positioning column and sliding it onto the unloading and cooling table. The whole process requires no manual intervention, improving the production efficiency, reducing the safety risks that may be brought by manual operations, and optimizing the working process of automotive part forming and welding.

All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0046] Embodiment 1: Please refer to Figures 1 to 9 :

[0047] The present invention proposes a welding device for forming automobile parts, comprising: a welding table 1; a frame 2 is vertically upwardly provided on the back of the welding table 1, a welding machine 3 and a controller 4 are provided on the upper end of the frame 2, an inverted cylinder 5 is also provided on the frame 2, and the end of the piston rod of the cylinder 5 carries a welding head 301 connected to the welding machine 3, and the welding machine 3 and the controller 4 on the upper end of the frame 2 are respectively responsible for providing energy required for welding and intelligently controlling the operation of the entire equipment. The welding machine 3 can output stable current, voltage and other parameters that are suitable for different welding process requirements to ensure the reliability of welding quality; the controller 4 accurately adjusts the action sequence and operation status of each component of the equipment according to the preset program and real-time feedback signal to realize automated operation, greatly improve production efficiency and stability, and reduce the errors that may be caused by manual intervention; the frame 2 below the cylinder 5 is provided with a "冂"-shaped vertical moving rail frame 6, and a slide 7 connected to the end of the piston rod of the cylinder 5 is vertically slidably installed on the vertical moving rail frame 6; a smoking box 9 for sucking welding smoke is provided on the outer wall of the slide 7; the lower end of the slide 7 is vertically fixedly connected with a horizontal "匚"-shaped connecting plate 8 through a downwardly extending hanging plate 701; a buffer connecting seat 10 is provided at the lower position of the middle part of the connecting plate 8, and a clamping seat 11 for squeezing and fixing parts is provided at the lower end of the buffer connecting seat 10. The inverted cylinder 5 on the frame 2 drives the welding head 301 connected to the welding machine 3 to achieve vertical displacement through the extension and contraction of its piston rod. This design enables the welding head 301 to accurately approach or move away from the parts to be welded, ensuring the accuracy of the welding position. The power output of the cylinder 5 is stable and responsive. Compared with other driving methods, it can complete the positioning of the welding head 301 in a short time, effectively shortening the welding cycle. At the same time, the "冂"-shaped vertical sliding rail frame 6 provides a precise vertical sliding track for the slide 7. The slide 7 is connected to the end of the piston rod of the cylinder 5, which not only enhances the stability of the structure, but also makes the slide 7 more stable during movement, further ensuring the positioning accuracy of the welding head 301. The design that the back of the hanging plate 701 is always tangent to the vertical rail of the vertical moving rail frame 6 optimizes the moving trajectory of the slide 7, reduces shaking and deviation during operation, and ensures the accuracy of the welding operation;

[0048] A tooling tray 12 for placing automobile parts is provided at the upper end of the welding table 1. The end of the tooling tray 12 away from the frame 2 is rotatably connected to the welding table 1, and an end of the welding table 1 away from the frame 2 is provided with a unloading cooling table 13 connected to the tooling tray 12. The tooling tray 12 can be rotated upward to unload the automobile parts thereon into the unloading cooling table 13.

[0049] Among them, a limit switch 601 is provided at the bottom of the top frame of the vertical rail frame 6. When the slide 7 moves up to the extreme position, the limit switch 601 is squeezed and triggered, and the welding machine 3, the cylinder 5 and the smoking box 9 are interlocked and stop working.

[0050] The back of the hanging plate 701 is always tangent to the vertical rail of the vertical rail frame 6 .

[0051] Wherein, at positions near the ends of the left and right cantilevers of the connecting plate 8, two hook-pulling arms 801 are respectively arranged vertically downward. The hook-pulling arm 801 at the outermost end is longer than the inner hook-pulling arm 801. Barbs 8011 are provided at the ends of the hook-pulling arms 801. The size of the barb 8011 of the hook-pulling arm 801 at the outermost end is larger than that of the barb 8011 on the inner hook-pulling arm 801. The hook-pulling arms 801 slide downward along the side wall of the tooling plate 12.

[0052] Wherein, a smoke exhaust pipe 901 for discharging the purified flue gas is provided on one side of the smoking box 9. A smoke exhaust fan 9011 is built in the smoke exhaust pipe 901. An external thread 9012 for connecting an external smoke removal pipe is further provided on the outer wall of the smoke exhaust pipe 901. The smoking box 9 arranged on the outer wall of the sliding seat 7 is specifically used for sucking the harmful welding fumes generated during the welding process. The smoke exhaust pipe 901 on one side of the smoking box 9 is internally provided with the smoke exhaust fan 9011. The strong suction force can quickly suck the welding fumes into the interior of the smoking box 9. The external thread 9012 on the outer wall of the smoke exhaust pipe 901 facilitates the connection with an external professional smoke removal pipe, further enhancing the welding fume treatment capacity. The purified air can be safely discharged, effectively improving the working environment, protecting the physical health of the operators, meeting the environmental protection requirements, and reducing the pollution to the surrounding environment.

[0053] Wherein, the buffer connecting seat 10 is in an inverted "L" shape. Two buffer rods 1001 are symmetrically and vertically arranged at the upper end of the buffer connecting seat 10. The buffer rods 1001 are vertically and slidably connected to the connecting plate 8. Buffer springs 1002 that always push the buffer connecting seat 10 downward are sleeved on the buffer rods 1001. At least two lifting holes 1003 are vertically arranged at the lower end of the middle part of the buffer connecting seat 10. The lifting holes 1003 are used for installing the clamping seat 11. Under the natural action of the buffer springs 1002, the lower end of the clamping seat 11 is lower than the lower end of the welding head 301.

[0054] Among them, an inner card slot 1101 for accommodating the lower end of the buffer connecting seat 10 is opened upward at the upper end of the clamping seat 11. The middle part of the upper end of the clamping seat 11 is installed in the hoisting hole 1003 through a hoisting bolt 1102. The clamping seat 11 can make a small deflection with the hoisting bolt 1102 as the rotation axis and use the two ends and corners at the bottom of the buffer connecting seat 10 as deflection limit stops. The hoisting bolt 1102 is installed in hoisting holes 1003 with different heights, and the deflectable angle of the clamping seat 11 changes accordingly to clamp parts with different shapes. A smoking head 1103 is provided on the bottom of the clamping seat 11 and penetrates toward the side where the welding head 301 is located. The other end of the smoking head 1103 is fixedly connected to a pretreatment box 1104 through a metal connecting pipe. The pretreatment box 1104 is filled with flue gas filtering materials. A lifting hose 1105 is provided at the upper end of the pretreatment box 1104 and is connected to the smoking box 9 for discharging flue gas. Pad columns 1106 with adjustable upper and lower heights are symmetrically screwed on the left and right sides of the bottom of the clamping seat 11. The pad columns 1106 clamp and fix the automotive parts on the tooling plate 12. The air cylinder 5 pushes the sliding seat 7 downward, and the welding head 301 moves downward for welding. The connecting plate 8, the buffer connecting seat 10, and part of the clamping seat 11 move downward accordingly. The clamping seat 11 first contacts the metal part and squeezes and clamps it, and then the welding head 301 performs welding. The "C"-shaped connecting plate 8 connected to the lower end of the sliding seat 7 through a hanging plate 701 provides an installation basis for the buffer connecting seat 10 and the clamping seat 11. The buffer connecting seat 10 adopts an inverted "L" shape structure. The buffer rod 1001 at its upper end is vertically slidably connected to the connecting plate 8. The buffer spring 1002 sleeved on the buffer rod 1001 plays a key buffer role during the operation of the equipment. When the clamping seat 11 contacts the part to be welded, the buffer spring 1002 can absorb part of the impact force, avoid damaging the part due to excessive instantaneous pressure, and at the same time ensure the uniformity of the clamping force, making the part more stable during the welding process. The clamping seat 11 is installed in the hoisting hole 1003 of the buffer connecting seat 10 through the hoisting bolt 1102, and the deflectable angle can be adjusted according to the shape of the part. This design greatly improves the adaptability of the equipment to parts with different shapes and expands the application range of the equipment. The height of the pad columns 1106 at the bottom of the clamping seat 11 is adjustable, and can accurately clamp and fix the automotive parts on the tooling plate 12, ensuring that the parts do not displace during the welding process and guaranteeing the welding quality.

[0055] Example 2. On the basis of Example 1, positioning posts are provided on the top plane of the tooling plate 12 according to the shape of the automotive parts. A "π"-shaped ejecting member 1201 is also provided in the top plane of the tooling plate 12. One end of the ejecting member 1201 close to the unloading and cooling table 13 is connected by a rotating shaft. The other long side of the ejecting member 1201 extends to the outer side wall at the other end of the tooling plate 12. A reset elastic cord 1205 is connected between the long side of the ejecting member 1201 and the tooling plate 12. The reset elastic cord 1205 is used to limit the opening and closing angle between the ejecting member 1201 and the tooling plate 12 and provide the reset ability for the ejecting member 1201. Locking members 1202 are provided at the positions corresponding to the short hook arms 801 on the left and right side walls of the tooling plate 12. Locking members 1202 are also provided at both ends of the long side of the ejecting member 1201. The locking members 1202 here are vertically corresponding to the long hook arms 801. A locking post 1203 is horizontally slidably installed in each of the locking members 1202 toward the side of the frame 2. The end of the locking post 1203 is a semi-cylindrical head structure. A locking spring 1204 that always pushes the head structure toward the side of the frame 2 is sleeved on the locking post 1203. The lengths of the locking post 1203 and the locking spring 1204 on the ejecting member 1201 are both greater than the lengths of the locking post 1203 and the locking spring 1204 on the tooling plate 12. When the connecting plate 8 moves downward, the hook arm 801 moves downward, and the barb 8011 presses the locking post 1203 to continue moving downward until the welding head 301 welds the automotive parts. After welding and resetting, the connecting plate 8 moves upward. The barb 8011 of the short hook arm 801 first contacts the head of the locking post 1203 on the tooling plate 12 and drives the tooling plate 12 to turn up. Then the barb 8011 of the long hook arm 801 contacts the head of the locking post 1203 on the ejecting member 1201, driving the ejecting member 1201 to turn out from the tooling plate 12, pushing the automotive parts on the tooling plate 12 out of the positioning posts and sliding them into the unloading and cooling table 13 by their own gravity. The connecting plate 8 continues to move upward, and the barb 8011 is disengaged from the head of the locking post 1203. Both the tooling plate 12 and the ejecting member 1201 are reset. The tooling plate 12 at the upper end of the welding table 1 is used to place the automotive parts to be welded. The positioning posts provided on the top plane of the tooling plate 12 according to the shape of the parts can quickly and accurately position the parts, improving the feeding efficiency and positioning accuracy. One end of the tooling plate 12 far from the frame 2 is rotatably connected to the welding table 1. Cooperating with the unloading and cooling table 13, it realizes the automatic unloading and cooling of the parts after welding. In Example 2, the "π"-shaped ejecting member 1201 on the top plane of the tooling plate 12 is connected to the tooling plate 12 by a reset elastic cord 1205, which plays an important role in the unloading process. The locking members 1202, the locking posts 1203, and the locking springs 1204 provided on the tooling plate 12 and the ejecting member 1201 cooperate with the hook arms 801 on the connecting plate 8 to realize the automatic connection of the welding and unloading processes.After welding is completed, the connecting plate 8 moves upward. The barb 8011 of the short hook pulling arm 801 first drives the tooling plate 12 to turn up, and then the barb 8011 of the long hook pulling arm 801 drives the ejecting member 1201 to turn up, pushing the component out of the positioning post and sliding it onto the unloading and cooling table 13. The whole process requires no manual intervention, improving production efficiency and reducing the safety risks that may be brought by manual operation.

[0056] The working principle of this embodiment:

[0057] During the forming and welding operation of automotive components, the automotive components to be welded are placed on the tooling plate 12 of the welding table 1. The positioning posts on the top plane of the tooling plate 12 accurately position the components according to their shapes. At this time, the welding machine 3 and the controller 4 at the upper end of the frame 2 are ready, and the inverted cylinder 5 on the frame 2 starts to work under the control of the controller 4. The piston rod of the cylinder 5 drives the sliding seat 7 to move vertically along the vertical moving rail frame 6. A smoking box 9 for sucking welding fumes is installed on the outer wall of the sliding seat 7. A smoke exhaust fan 9011 is built into the smoke exhaust pipe 901 on one side of it, which can discharge the purified fumes. The external thread 9012 on the outer wall of the smoke exhaust pipe 901 facilitates the connection of an external smoke removal pipe.

[0058] As the cylinder 5 pushes the sliding seat 7 downward, the connecting plate 8, the buffer connecting seat 10, and the clamping seat 11 also descend. The clamping seat 11 first contacts the automotive component on the tooling plate 12 through the cushion post 1106. Since the buffer connecting seat 10 is in an inverted "L" shape, the buffer rod 1001 at its upper end is vertically slidably connected to the connecting plate 8, and the buffer spring 1002 sleeved on the buffer rod 1001 always pushes the buffer connecting seat 10 downward, enabling the clamping seat 11 to stably squeeze and clamp the component first. The clamping seat 11 can be installed in the lifting holes 1003 at different heights of the buffer connecting seat 10 through the lifting bolts 1102, thereby changing its deflectable angle to adapt to the clamping requirements of components with different shapes. At the same time, the smoking head 1103 at the bottom of the clamping seat 11 conveys the welding fumes generated during welding to the pretreatment box 1104 filled with fume filtering materials through a metal connecting pipe. After preliminary filtration, it is then sent to the smoking box 9 through the lifting hose 1105 for further purification treatment.

[0059] When the sliding seat 7 moves downward to a certain position, the welding head 301 starts to perform welding operations on the fixed automotive components. During the welding process, the smoking box 9 keeps working, sucking the welding fumes generated in time to keep the working environment clean. When the sliding seat 7 moves upward to the limit position, the limit switch 601 at the bottom of the top frame of the vertical moving rail frame 6 is triggered by being squeezed. At this time, the welding machine 3, the cylinder 5, and the smoking box 9 all stop working in an interlocked manner to ensure the safe operation of the equipment.

[0060] After welding is completed, the connecting plate 8 moves upward along with the sliding seat 7. The hook pulling arms 801 at both the left and right ends of the connecting plate 8 also rise accordingly. The barb 8011 of the short hook pulling arm 801 first comes into contact with the head body of the locking column 1203 on the tooling plate 12. Since the locking spring 1204 is sleeved on the locking column 1203, under the action of the barb 8011, the locking column 1203 is squeezed. As the connecting plate 8 continues to move upward, it drives the tooling plate 12 to rotate upward with the rotation connection point between it and the welding table 1 as the axis. Then, the barb 8011 of the long hook pulling arm 801 comes into contact with the head body of the locking column 1203 on the ejecting member 1201. By the same principle, it drives the ejecting member 1201 to flip up from the tooling plate 12, and pushes out the automotive parts in the positioning columns on the tooling plate 12. The parts slide down to the unloading and cooling table 13 by their own gravity for cooling. The connecting plate 8 continues to rise, and the barb 8011 is disengaged from the head body of the locking column 1203. The tooling plate 12 and the ejecting member 1201 are reset under the action of the reset elastic cord 1205, and are ready for the next welding operation.
