Description

Technical Field

[0001] The present invention relates to the technical field of automotive parts manufacturing, and particularly to a forming and welding device for automotive parts. Background Art

[0002] Traditional forming and welding devices for automotive parts have many deficiencies in tooling and unloading structures. On the one hand, during loading, the positioning efficiency of parts is low and the accuracy is poor. Often, manual repeated measurement and adjustment are 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, high labor intensity. Moreover, during manual unloading, the already welded parts may be damaged secondarily due to improper operation, and there are also certain safety risks, such as scalding and smashing. In addition, the connection between the entire welding and unloading processes is not smooth, resulting in discontinuous production processes and reduced overall production efficiency. At the same time, traditional forming and welding devices for automotive parts often have 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 part fixation and buffering. For example, some devices use rigid fixation methods. When clamping parts, due to the lack of buffering measures, the surface of the parts is easily deformed and cracked due to excessive instantaneous pressure, affecting the performance of the parts. Moreover, the clamping devices of traditional devices usually have fixed structures and are difficult to be flexibly adjusted according to parts of different shapes, limiting the application range of the devices. In addition, due to inaccurate fixation, the parts may have small displacements during the welding process, resulting in weld deviations and reduced welding quality. Summary of the Invention

[0003] The present invention relates to a forming and welding device for automotive parts. In terms of part positioning and fixation, the cylinder drives the welding head to move vertically precisely, and the "冂"-shaped vertical moving rail frame provides an accurate sliding track for the sliding seat, ensuring the accuracy of the welding position and shortening the welding cycle. At the same time, the design of the buffer connecting seat and the clamping seat is very ingenious. The buffer spring can absorb the impact force during clamping, 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, combined with the height-adjustable cushion column, improving the adaptability to parts of different shapes, ensuring that the parts do not displace during welding, and further improving the welding quality.

The tooling plate can be rotated upward to unload the automotive parts thereon into the discharging and cooling table.

[0005] Optionally, a limit switch is provided at the bottom of the top frame of the vertical moving rail frame. When the sliding seat moves up to the limit position, the limit switch is triggered by extrusion, and the welding machine, the cylinder and the smoking box are all interlocked to stop working.

[0006] Optionally, the back of the hanging plate is always tangent to the vertical rail of the vertical moving rail frame.

[0007] Optionally, two hook pulling arms are respectively vertically downward provided at positions near the ends of the cantilevers at the left and right ends of the connecting plate. The hook pulling arm at the outermost end is longer than the inner hook pulling arm. The ends of the hook pulling arms are all provided with barbs. The barb of the hook pulling arm at the outermost end is larger in size than the barb on the inner hook pulling arm, and the hook pulling arms slide downward along the side wall of the tooling plate.

[0008] Optionally, a smoke exhaust pipe for discharging the purified smoke is provided on one side of the smoking box. A smoke exhaust fan is内置 in the smoke exhaust pipe, and an external thread for externally connecting a smoke removal pipe is further provided on the outer wall of the smoke exhaust pipe.

[0009] Optionally, the buffer connecting seat is an inverted "L"-shaped structure. Two buffer rods are symmetrically vertically provided at the upper end of the buffer connecting seat. The buffer rods are vertically slidably connected with the connecting plate. Buffer springs that always push the buffer connecting seat downward are套装 on the buffer rods. At least two lifting holes are vertically arranged at the lower end position in the middle of the buffer connecting seat. The lifting holes are used for installing the clamping seat. Under the natural action of the buffer springs, the lower end of the clamping seat is lower than the lower end of the welding head.

[0010] Optionally, the upper end of the clamping seat is upwardly provided with an inner groove for accommodating the lower end of the buffer connecting seat, and the middle part of the upper end of the clamping seat is installed in the lifting hole through a lifting bolt. The clamping seat can be slightly deflected by the lifting bolt as the rotation axis, and the two end corners of the bottom of the buffer connecting seat are used as deflection limit stops. The lifting bolts are installed in lifting holes of different heights, and the deflection angle of the clamping seat changes accordingly to clamp parts of different shapes. The bottom of the clamping seat is penetrated by a side facing the welding head and a smoking head is provided. The other end is fixedly connected to a pretreatment box through a metal connecting pipe. The pretreatment box is filled with smoke filtering materials. A lifting hose is provided on the upper end of the pretreatment box, which is connected to the smoking box for smoke exhaust. The bottom of the clamping seat is symmetrically screwed with up and down height-adjustable pads. The pads clamp and fix the automobile parts on the tooling plate. The cylinder pushes the slide seat downward, and the welding head moves downward for welding. The connecting plate, buffer seat and clamping seat part follow and move downward. The clamping seat first contacts the metal parts, squeezes and clamps them, and then the welding head is welded.

[0011] Optionally, a positioning column is provided on the top plane of the tooling disk according to the shape of automobile parts, and a "π"-shaped pop-up piece is also provided in the top plane of the tooling disk. The end of the pop-up piece close to the unloading cooling table is connected by a rotating shaft, and the long side of the other end of the pop-up piece extends to the outer wall of the other end of the tooling disk. A reset elastic rope is connected between the long side of the pop-up piece and the tooling disk, and the reset elastic rope is used to limit the opening and closing angle between the pop-up piece and the tooling disk and provide a reset ability for the pop-up piece. Padlock pieces are provided at the positions corresponding to the short hook pull arms on the left and right side walls of the tooling disk, and padlock pieces are also provided at the two ends of the long side of the pop-up piece, and the padlock pieces thereat correspond vertically to the long hook pull arms. A padlock column is installed in the padlock piece for horizontal sliding toward one side of the frame, and the end of the padlock column is a semi-cylindrical head body structure. The lock column is equipped with a padlock spring that always pushes the head body structure to one side of the frame. The length of the padlock column and the padlock spring on the pop-up piece are both greater than the length of the padlock column and the padlock spring on the tooling disk. When the connecting plate moves downward, the hook arm moves downward, and the barb squeezes the padlock column and continues to move downward until the welding head welds the automotive parts. After welding, it resets, and the connecting plate moves upward. The barb of the short hook arm first contacts the padlock column head body on the tooling disk, and drives the tooling disk to flip up. The barb of the long hook arm contacts the padlock column head body on the pop-up piece again, driving the pop-up piece to flip from the tooling disk, pushing the automotive parts on the tooling disk out of the positioning column and sliding them to the unloading cooling table by their own gravity. The connecting plate continues to move upward, the barb is decoupled from the padlock column head body, and the tooling disk and the pop-up piece are reset.

[0012] The present invention provides a welding device for automobile parts forming, which has the following beneficial effects: 1. In terms of the welding power and control structure, the welding machine and controller installed at the upper end of the frame are the core. The welding machine can output parameters such as stable current and voltage that are adapted to different welding process requirements. This characteristic ensures the reliability of welding quality when facing the welding requirements of various automotive parts. The controller precisely regulates the action sequence and operating state of each component of the equipment according to the preset program and real-time feedback signals. Different from traditional equipment that relies on manual experience for operation, this equipment realizes automated operation, greatly improving production efficiency and stability, and effectively reducing the errors that may be brought by manual intervention.

[0013] 2. In terms of the welding execution and positioning structure, the inverted cylinder and the "冂"-shaped vertical moving rail frame work together. The piston rod of the cylinder drives the welding head to move vertically, with stable power output and rapid response. 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 moving rail frame provides an accurate vertical sliding track for the sliding seat, and the sliding seat is connected to the end of the piston rod of the cylinder, enhancing the structural stability and making the movement of the sliding seat smoother, further ensuring 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 moving rail frame optimizes the movement track of the sliding seat, reduces running晃动 and deviation, and ensures the accuracy of welding operation.

[0014] 3. In terms of the component fixing and buffering structure, the "匚"-shaped connecting plate connected to the lower end of the sliding seat through the hanging plate provides an installation basis for the buffer connecting seat and the clamping seat. The buffer connecting seat adopts an inverted "L" shape, and the buffer rod at the upper end is vertically slidably connected to the connecting plate, and a buffer spring is sleeved on the buffer rod. When the clamping seat contacts the component to be welded, the buffer spring absorbs part of the impact force, avoiding damage to the component caused by excessive instantaneous pressure, and at the same time ensuring uniform clamping force, making the component more stable during the welding process. The clamping seat is installed in the lifting holes at different heights of the buffer connecting seat through lifting bolts, and the deflection angle can be adjusted according to the shape of the component, greatly improving the adaptability of the equipment to components of different shapes and expanding the application range of the equipment. The upper and lower height-adjustable cushion columns symmetrically screwed at the bottom of the clamping seat can accurately clamp and fix the automotive components on the tooling plate, ensuring that the components do not displace during the welding process and guaranteeing the welding quality.

[0015] 4. In terms of the welding fume treatment structure, the smoking box on the outer wall of the sliding seat and the supporting exhaust pipe are ingeniously designed. An exhaust fan is built into the exhaust pipe, and the strong suction quickly sucks the welding fume into the smoking box. The external thread on the outer wall of the exhaust pipe is convenient for connecting to the external professional fume removal pipeline, further enhancing the welding fume treatment ability. At the same time, the smoking head at the bottom of the clamping seat is connected to the pretreatment box filled with fume filtering materials through a metal connecting pipe. After preliminary filtration, it is sent to the smoking box through a lifting hose for further purification treatment. This series of structures effectively improves the working environment, protects the physical health of operators, also meets the environmental protection requirements, reduces pollution to the surrounding environment, and is a major improvement over traditional welding equipment that ignores the harm of welding fume.

[0016] 5. In the tooling and unloading structure, the tooling tray at the upper end of the welding table has positioning columns on the top plane according to the shape of the parts, which can quickly and accurately position the parts and improve the loading efficiency and positioning accuracy. The end of the tooling tray away from the frame is rotatably connected to the welding table, and cooperates with the unloading cooling table to realize the automatic unloading and cooling of the parts after welding. In particular, in the second embodiment, the padlock, padlock column, and padlock spring provided on the tooling tray and the pop-up part cooperate with the hook arm on the connecting plate to realize the automatic connection of the welding and unloading processes. After the welding is completed, the connecting plate is moved up, the barb of the short hook arm first drives the tooling tray to turn up, and the barb of the long hook arm drives the pop-up part to turn up, and the parts are pushed out of the positioning column and slide to the unloading cooling table. The whole process does not require manual intervention, which improves production efficiency, reduces the safety risks that may be caused by manual operation, and optimizes the workflow of automobile parts forming welding.

The welding machine 3 can output parameters such as stable current and voltage that are adapted to different welding process requirements, ensuring the reliability of welding quality; the controller 4 precisely regulates the action sequence and operating state of each component of the device according to the preset program and real-time feedback signals, realizing automated operation, greatly improving production efficiency and stability, and reducing the errors that may be brought by manual intervention; a "冂"-shaped vertical movement rail frame 6 is provided on the frame 2 below the cylinder 5, and a sliding seat 7 connected to the end of the piston rod of the cylinder 5 is vertically slidably installed on the vertical movement rail frame 6; a smoking box 9 for sucking welding fumes is provided on the outer wall of the sliding seat 7; the lower end of the sliding seat 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 middle position 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 telescopic movement 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 the response is rapid. 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 movement rail frame 6 provides an accurate vertical sliding track for the sliding seat 7. The sliding seat 7 is connected to the end of the piston rod of the cylinder 5, which not only enhances the structural stability, but also makes the sliding seat 7 move more smoothly during the 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 movement rail frame 6 optimizes the movement track of the sliding seat 7, reduces the shaking and deviation during the operation, and ensures the accuracy of the welding operation; A tooling plate 12 for placing automotive parts is provided at the upper end of the welding table 1. One end of the tooling plate 12 away from the frame 2 is rotatably connected to the welding table 1, and a discharging and cooling table 13对接 with the tooling plate 12 is provided at the end of the welding table 1 away from the frame 2. The tooling plate 12 can be rotated upward to unload the automotive parts thereon into the discharging and cooling table 13.

One end of the tooling plate 12 away from the frame 2 is rotatably connected to the welding table 1, and a discharging and cooling table 13对接 with the tooling plate 12 is provided at the end of the welding table 1 away from the frame 2. The tooling plate 12 can be rotated upward to unload the automotive parts thereon into the discharging and cooling table 13. ", there seems to be an incorrect expression "对接" which should be something like "connected in a butt-joint manner" or other more appropriate words. Please check and correct the original text if possible for a more accurate translation.

[0025] Among them, two hook arms 801 are respectively provided vertically downward at the positions of the cantilevers at the left and right ends of the connecting plate 8 near the ends. The hook arm 801 at the very end is longer than the hook arm 801 on the inner side. The ends of the hook arms 801 are provided with hooks 8011. The size of the hook 8011 of the hook arm 801 at the very end is larger than the hook 8011 on the inner side of the hook arm 801.

The smoke exhaust pipe 901 on one side of the smoke exhaust box 9 has a built-in smoke exhaust fan 9011, and the strong suction force can quickly suck the welding smoke into the smoke exhaust box 9. The external thread 9012 on the outer wall of the smoke exhaust pipe 901 is convenient for connection with an external professional smoke removal pipe, further enhancing the welding smoke processing capacity, and the purified air can be safely discharged, effectively improving the working environment, protecting the health of the operators, and also meeting environmental protection requirements and reducing pollution to the surrounding environment.

[0027] Among them, the buffer seat 10 is an inverted "L"-shaped structure, and two buffer rods 1001 are vertically symmetrically arranged at the upper end of the buffer seat 10. The buffer rods 1001 are vertically slidably connected to the connecting plate 8. The buffer rods 1001 are provided with buffer springs 1002 that always push the buffer seat 10 downward. At least two lifting holes 1003 are vertically arranged at the lower end of the middle part of the buffer seat 10. The lifting holes 1003 are used to install the clamping seat 11. Under the natural action of the buffer spring 1002, the lower end of the clamping seat 11 is lower than the lower end of the welding head 301.

[0028] 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 the two end corners at the bottom of the buffer connecting seat 10 are used 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 smoke suction 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 smoke suction head 1103 is fixedly connected to a pretreatment box 1104 through a metal connecting pipe. The pretreatment box 1104 is filled with a flue gas filtering material. A lifting hose 1105 is provided at the upper end of the pretreatment box 1104 and is connected to the smoke suction 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 will not displace during the welding process and guaranteeing the welding quality.

[0029] Embodiment 2, on the basis of embodiment 1, a positioning column is provided on the top plane of the tooling tray 12 according to the shape of the automobile parts, and a "π"-shaped pop-up member 1201 is also provided in the top plane of the tooling tray 12. One end of the pop-up member 1201 close to the unloading cooling table 13 is connected by a rotating shaft, and the other end of the long side of the pop-up member 1201 extends to the outer side wall of the other end of the tooling tray 12. A reset elastic rope 1205 is connected between the long side of the pop-up member 1201 and the tooling tray 12, and the reset elastic rope 1205 is used to limit the pop-up member 1201 and the tooling tray 1 2, and provides reset capability for the pop-up member 1201. Padlock members 1202 are provided at positions corresponding to the short hook and pull arms 801 on the left and right side walls of the tooling tray 12. Padlock members 1202 are also provided at both ends of the long sides of the pop-up member 1201. The padlock members 1202 therein correspond vertically to the long hook and pull arms 801. Padlock columns 1203 are installed in the padlock members 1202 to slide horizontally toward one side of the frame 2. The end of the padlock column 1203 is a semi-cylindrical head structure. The padlock column 1203 is always mounted to keep the head structure toward the frame. 2 The padlock spring 1204 is pushed on one side, and the lengths of the padlock column 1203 and the padlock spring 1204 on the pop-up member 1201 are greater than the lengths of the padlock column 1203 and the padlock spring 1204 on the tooling plate 12. When the connecting plate 8 moves downward, the hook arm 801 moves downward, and the barb 8011 squeezes the padlock column 1203 and continues to move downward until the welding head 301 welds the automobile parts. After welding, it is reset, and the connecting plate 8 moves upward, and the barb 8011 of the short hook arm 801 first connects with the head of the padlock column 1203 on the tooling plate 12. The tooling tray 12 is touched and driven to flip up. The barb 8011 of the long hook arm 801 contacts the head of the padlock column 1203 on the pop-up member 1201, driving the pop-up member 1201 to flip over from the tooling tray 12, pushing the auto parts on the tooling tray 12 out of the positioning column and sliding them to the unloading cooling table 13 by their own gravity. The connecting plate 8 continues to move up, and the barb 8011 is unhooked from the head of the padlock column 1203. The tooling tray 12 and the pop-up member 1201 are both reset. The tooling tray 12 at the upper end of the welding table 1 is used to place the auto parts to be welded. The positioning column set on the top plane of the tooling tray 12 according to the shape of the parts can quickly and accurately position the parts, thereby improving the feeding efficiency and positioning accuracy. The end of the tooling tray 12 away from the frame 2 is rotatably connected to the welding table 1, and cooperates with the unloading cooling table 13 to realize the automatic unloading and cooling of the parts after welding. In the second embodiment, the "π"-shaped ejection piece 1201 on the top plane of the tooling tray 12 is connected to the tooling tray 12 through a reset elastic rope 1205, and plays an important role in the unloading process. The padlock 1202, padlock column 1203, and padlock spring 1204 provided on the tooling tray 12 and the ejection piece 1201 cooperate with the hook arm 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 up, and the hook 8011 of the short hook pulling arm 801 first drives the tooling plate 12 to flip up, and the hook 8011 of the long hook pulling arm 801 then drives the pop-up piece 1201 to flip up, pushing the parts out of the positioning column and sliding them to the unloading cooling table 13. The whole process does not require manual intervention, which improves production efficiency and reduces the safety risks that may be caused by manual operation.

[0030] The working principle of this embodiment: During the forming welding operation of automobile parts, the automobile parts to be welded are placed on the tooling plate 12 of the welding table 1, and the positioning columns on the top plane of the tooling plate 12 accurately position them according to the shape of the parts. At this time, the welding machine 3 and the controller 4 on the upper end of the frame 2 are ready, and the inverted cylinder 5 on the frame 2 starts working under the control of the controller 4. The piston rod of the cylinder 5 drives the slide 7 to move vertically along the vertical rail frame 6. A smoking box 9 for extracting welding smoke is installed on the outer wall of the slide 7. The exhaust pipe 901 on one side thereof has a built-in exhaust fan 9011, which can discharge the purified smoke. The external thread 9012 on the outer wall of the exhaust pipe 901 is convenient for external smoke removal pipe.

[0031] As the cylinder 5 pushes the slide 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 automobile parts on the tooling plate 12 through the pad column 1106. Since the buffer connecting seat 10 is an inverted "L"-shaped structure, the buffer rod 1001 at its upper end is vertically slidably connected with the connecting plate 8, and the buffer spring 1002 set on the buffer rod 1001 always pushes the buffer connecting seat 10 downward, so that the clamping seat 11 can first stably squeeze and clamp the fixed parts. The clamping seat 11 can be installed in the lifting holes 1003 of different heights of the buffer connecting seat 10 through the lifting bolts 1102, so as to change its deflection angle to meet the clamping requirements of parts of different shapes. At the same time, the smoking head 1103 at the bottom of the clamping seat 11 transports the welding smoke generated by welding to the pretreatment box 1104 filled with smoke filter material through the metal connecting pipe. After preliminary filtration, it is sent to the smoking box 9 through the lifting hose 1105 for further purification.

[0032] When the slide 7 moves down to a certain position, the welding head 301 starts welding the fixed automobile parts. During the welding process, the smoke box 9 continues to work and timely sucks the welding smoke generated by welding to keep the working environment clean. When the slide 7 moves up to the extreme position, the limit switch 601 at the bottom of the top frame of the vertical rail frame 6 is squeezed and triggered. At this time, the welding machine 3, the cylinder 5 and the smoke box 9 are interlocked and stop working to ensure the safe operation of the equipment.

[0033] After welding is completed, the connecting plate 8 moves up along with the slide 7. The hook-pull arms 801 of the cantilever arms at the left and right ends of the connecting plate 8 also rise accordingly, and the short hook-pull arms 801 first contact the head of the padlock column 1203 on the tooling tray 12. Since the padlock spring 1204 is mounted on the padlock column 1203, the padlock column 1203 is squeezed under the action of the hook 8011. As the connecting plate 8 continues to move up, the tooling tray 12 is driven to flip upward with its rotation connection point with the welding table 1 as the axis. Then, the long hook-pull arms 801 contact the head of the padlock column 1203 on the ejection member 1201. By the same principle, the ejection member 1201 is driven to flip up from the tooling tray 12, and the auto parts in the positioning column on the tooling tray 12 are pushed out. The parts slide down to the unloading cooling table 13 by their own gravity for cooling. The connecting plate 8 continues to rise, the barb 8011 is unhooked from the head of the padlock column 1203, and the tooling plate 12 and the ejection member 1201 are both reset under the action of the reset elastic rope 1205, ready for the next welding operation.
