Description

Technical Field

[0001] This invention relates to the technical field of automotive parts processing equipment, specifically to an automated welding and forming equipment and process for automotive parts. Background Technology

[0002] In the automotive manufacturing industry, the welding and forming of tubular and block-shaped automotive parts is one of the core production processes, and its welding quality directly affects the assembly accuracy and operational safety of automobiles. With the automotive industry's ever-increasing demands for parts production efficiency, consistency, and environmental protection, traditional welding equipment and processes are no longer sufficient to meet the needs of large-scale, high-quality production.

[0003] Currently, most automotive parts welding relies on manual positioning. Before welding, operators need to manually adjust the part's mating position and angle. This not only results in high labor intensity and low production efficiency, but also easily leads to uneven part gaps and welding angle deviations due to human error. This can cause defects such as poor weld formation, slag inclusions, and incomplete penetration, seriously affecting the welding quality and service life of the parts.

[0004] Meanwhile, welding slag can easily accumulate around the weld or scratch the surface of the parts, affecting the welding quality and the precision of the parts; the fumes can directly diffuse into the environment, polluting the workshop air and endangering the health of the operators, which does not meet the requirements of green production. Summary of the Invention

[0008] According to one embodiment of the present invention, the clamping assembly further includes a guide rod and a limiting sleeve. The guide rod is horizontally fixedly connected to the movable clamping plate. The side of the placement groove is provided with a guide hole that slides with the guide rod. The outer side of the guide rod is provided with an external thread, and the inner side of the limiting sleeve is provided with an internal thread that mates with the guide rod.

[0009] According to one embodiment of the present invention, the clamping assembly further includes a first push rod, and two guide rods are provided and symmetrically arranged on the side of the movable clamping plate. The first push rod is fixedly connected to the movable slide and is located between the two guide rods. The telescopic end of the first push rod is fixedly connected to the movable clamping plate. The first push rod is an electric push rod.

[0010] According to one embodiment of the present invention, the clamping mechanism further includes a mating gear, which is fixedly connected to the rotating frame. The mating gears of the two sets of clamping mechanisms mesh with each other. An adjusting motor is fixedly installed at the bottom of the welding table, and the output end of the adjusting motor is fixedly connected to the rotating frame of any set of clamping mechanisms.

[0011] According to one embodiment of the present invention, the welding assembly includes a first frame, a second frame, and a welding head. The first frame is fixedly disposed on the inner side of the rotating ring, the second frame is slidably connected to the first frame along the radial direction of the rotating ring, and the welding head is fixedly connected to the second frame.

[0012] According to one embodiment of the present invention, the welding assembly further includes a second push rod, the second push rod being fixedly connected to the first frame, the telescopic end of the second push rod being fixedly connected to the second frame, and the second push rod being an electric push rod.

[0013] According to one embodiment of the present invention, the cleaning mechanism further includes a filter screen. A negative pressure chamber and a dust collection chamber are provided on the inner side of the collection box. A through groove is provided between the negative pressure chamber and the dust collection chamber. The fan and the filter screen are both fixedly arranged in the through groove. The filter screen is located at one end of the through groove near the dust collection chamber, and the fan is located at one end of the through groove near the negative pressure chamber. A through hole is provided on the side of the turntable. An air outlet and an air inlet are provided on the side of the collection box, which are respectively connected to the negative pressure chamber and the dust collection chamber. The air outlet and the air inlet are respectively connected to the corresponding through hole.

[0014] According to one embodiment of the present invention, the cleaning mechanism further includes a slag collection frame, and the side of the collection box is provided with a slot communicating with the dust collection chamber. The slag collection frame is fitted into the slot, and a sealing strip is embedded at the opening of the slot.

[0015] An automated welding and forming process for automotive parts includes the following steps: Step 1: The operator places the two parts to be welded on the top clamping components of the movable slide of the two sets of symmetrical clamping mechanisms, and starts the clamping components to firmly fix the parts; then, the operator controls the movable slide to slide horizontally along the rotating frame, and adjusts the docking distance of the two parts according to the preset weld gap requirements, so that the welding surfaces of the parts are initially aligned. Step 2: Drive the rotating frame to rotate relative to the welding table, causing the parts to be welded on the clamping assembly to rotate synchronously. Adjust the welding angle of the parts according to the welding requirements until the weld seam of the parts is inside the rotating ring. Then, the movable slide on the support frame slides horizontally so that the weld seam is located at the center of the rotating ring. Step 3: Drive the rotating ring to rotate, so that the welding components rotate around the weld seam to achieve multi-angle and all-round welding; at the same time, the cleaning mechanism is started simultaneously, and the fan in the collection box generates negative pressure. Through the two symmetrical turntables that cooperate with the rotating ring, a directional airflow is formed to quickly absorb the welding slag and dust generated during the welding process and guide them into the collection box for centralized collection, so as to avoid welding slag splashing or dust diffusion. Step 4: After the welding operation is completed, the welding assembly stops working and returns to its original position along with the movable slide; the clamping assembly releases its fixation on the finished part, the rotating frame and the movable slide return to their initial positions, and the cleaning mechanism continues to run for a preset time to thoroughly clean the welding slag and fumes remaining in the welding area; Step 5: After cleaning is completed, the operator removes the finished part, completing the single welding process. The equipment then awaits the welding of the next batch of parts.

[0016] The advantages of this invention compared to the prior art are: 1. Through the symmetrical design of two sets of clamping mechanisms, combined with the rotation function of the rotating frame and the horizontal adjustment function of the movable slide, it can not only ensure the precise docking of the two parts to be welded, but also flexibly adapt to the welding requirements of parts with different angles and specifications. It effectively avoids the deviation caused by manual positioning. The sliding adjustment of the movable slide and the rotation function of the rotating ring in the welding mechanism enable the welding assembly to cover the weld in all directions, ensuring that the weld is uniform and firm, and reducing the incidence of welding defects.

[0017] 2. From clamping and positioning the parts and adjusting the welding position, to the all-round welding of the weld seam and the synchronous collection of welding slag and dust, the entire process is automated and coordinated, which greatly reduces the number of manual operation steps. This not only improves production efficiency, but also avoids quality fluctuations caused by fatigue and improper operation during manual welding, thus ensuring the stability of the production process.

[0018] 3. The cleaning mechanism, through the cooperation of the fan and the turntable, forms a directional negative pressure airflow, which can collect welding slag and fumes generated during welding in real time. This not only avoids the accumulation of welding slag around the weld, which may affect subsequent welding or cause scratches on the surface of parts, but also prevents the spread of fumes and dust, which pollutes the workshop environment, protects the health of operators, and meets the requirements of green production.

[0027] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0028] like Figures 1 to 6 As shown, an automated welding and forming equipment for automotive parts includes a welding table 1, a clamping mechanism 2, a welding mechanism 3, and a cleaning mechanism 4. Two sets of clamping mechanisms 2 are symmetrically arranged on top of the welding table 1. Each clamping mechanism 2 includes a rotating frame 5, a movable slide 6, and a clamping assembly 7. The rotating frame 5 is rotatably connected to the welding table 1, and the movable slide 6 is slidably connected to the rotating frame 5 in a horizontal direction. The clamping assembly 7 is located on top of the movable slide 6. The welding mechanism 3 includes a support frame 8, a movable slide 9, and a rotating frame 1. The ring 10 and welding assembly 11 are fixedly connected to the support frame 8 and the welding table 1, and are located between the two sets of clamping mechanisms 2. The movable slide 9 is slidably connected to the support frame 8. The rotating ring 10 is rotatably connected to the movable slide 9. The welding assembly 11 is set inside the rotating ring 10. The cleaning mechanism 4 includes a collection box 12, a fan 13 and a turntable 14. There are two turntables 14 arranged symmetrically and rotatably connected to the rotating ring 10. The side of the turntable 14 is connected to the collection box 12. The fan 13 is set inside the collection box 12.

[0029] Before welding, two sets of symmetrically arranged clamping mechanisms 2 first complete the positioning and fixing of the parts. The operator places the automotive parts to be welded (such as tubular or block parts) on the clamping assembly 7 on the top of the movable carriage 6. The clamping assembly 7 quickly clamps the parts to prevent displacement during welding.

[0030] Subsequently, the movable slide 6 slides horizontally along the rotating frame 5, which can precisely adjust the docking distance of the parts to ensure that the weld gap meets the welding requirements; while the rotation of the rotating frame 5 and the welding table 1 can drive the clamped parts to rotate synchronously, flexibly adjust the welding angle of the parts, and adapt to different welding needs such as joint welding and circumferential welding.

[0031] Once the parts are positioned, the rotating frame 5 is driven to rotate relative to the welding table 1, causing the parts to be welded on the clamping assembly 7 to rotate synchronously. The welding angle of the parts is adjusted according to the welding requirements until the weld seam of the parts is within the rotating ring 10. Then, the movable slide 9 on the support frame 8 slides horizontally so that the weld seam is located at the center of the rotating ring 10. The rotation of the rotating ring 10 and the movable slide 9 can drive the welding assembly 11 to rotate around the weld seam, realizing multi-angle and all-round welding and ensuring that the weld seam is uniform and complete.

[0032] During the welding process, the cleaning mechanism 4 operates synchronously, and the fan 13 in the collection box 12 starts to generate negative pressure. Through the two symmetrical turntables 14 that rotate with the rotating ring 10, a directional airflow is formed, which quickly adsorbs the welding slag and dust generated during welding to the side of the turntable 14 and guides it into the collection box 12 for centralized collection, so as to avoid welding slag splashing affecting the welding quality or polluting the environment.

[0033] After welding is completed, the clamping assembly 7 is released, and the rotating frame 5 and the movable slide 6 are reset, making it easy to remove the finished parts. At the same time, the cleaning mechanism 4 continues to work for a period of time to ensure that the welding slag and fumes remaining in the welding area are thoroughly cleaned.

[0034] The symmetrical design of the two clamping mechanisms 2, combined with the rotation function of the rotating frame 5 and the horizontal adjustment function of the movable slide 6, ensures the precise docking of the two parts to be welded and flexibly adapts to the welding requirements of parts with different angles and specifications. This effectively avoids deviations caused by manual positioning. The sliding adjustment of the movable slide 9 and the rotation function of the rotating ring 10 in the welding mechanism 3 enable the welding assembly 11 to cover the weld in all directions, ensuring that the weld is uniform and firm, and reducing the incidence of welding defects.

[0035] From clamping and positioning of parts and adjusting welding positions to all-round welding of weld seams and synchronous collection of welding slag and fumes, the entire process is automated and coordinated, greatly reducing manual operation steps. This not only improves production efficiency but also avoids quality fluctuations caused by fatigue and improper operation during manual welding, ensuring the stability of the production process.

[0036] The cleaning mechanism 4, through the cooperation of the fan 13 and the turntable 14, forms a directional negative pressure airflow, which can collect welding slag and fumes generated during welding in real time. This not only avoids the accumulation of welding slag around the weld, which may affect subsequent welding or cause scratches on the surface of parts, but also prevents the spread of fumes and dust, which pollutes the workshop environment, protects the health of operators, and meets the requirements of green production.

[0037] According to one embodiment of the present invention, the clamping assembly 7 includes a movable clamping plate 15 and an elastic pad 16. A placement groove is provided on the top of the movable slide 6. The movable clamping plate 15 is slidably connected to the side wall of the placement groove. Two movable clamping plates 15 are provided and arranged symmetrically. An arc-shaped clamping groove is provided on the side of each movable clamping plate 15. The arc-shaped clamping groove can conform to the outer surface of tubular, block-shaped, or other parts, increasing the contact area. The elastic pad 16 is fixedly disposed within the arc-shaped clamping groove. When the movable clamping plates 15 clamp towards each other, the elastic pad 16 is compressed and deformed, completely conforming to the surface contour of the part. Through the sliding clamping action of the movable clamping plates 15, combined with the deformation compensation of the elastic pad 16, a wrap-around clamping of parts of different shapes and sizes is achieved, avoiding localized pressure concentration.

[0038] According to one embodiment of the present invention, the clamping assembly 7 further includes a guide rod 17 and a limiting sleeve 18. The guide rod 17 is horizontally fixedly connected to the movable clamping plate 15. A guide hole is provided on the side of the placement groove to slide with the guide rod 17. The outer side of the guide rod 17 is provided with an external thread, and the inner side of the limiting sleeve 18 is provided with an internal thread to cooperate with the guide rod 17. When the movable clamping plate 15 is adjusted to a suitable clamping position, the external thread on the outer side of the guide rod 17 cooperates with the internal thread of the limiting sleeve 18, and the limiting sleeve 18 is rotated to press against the side wall of the placement groove, thereby limiting the sliding stroke with the movable clamping plate 15 and preventing the clamping assembly 7 from crushing the automotive parts.

[0039] According to one embodiment of the present invention, the clamping assembly 7 further includes a first push rod 19. Two guide rods 17 are provided and symmetrically arranged on the side of the movable clamping plate 15. The first push rod 19 is fixedly connected to the movable slide 6 and located between the two guide rods 17. The telescopic end of the first push rod 19 is fixedly connected to the movable clamping plate 15. The first push rod 19 is an electric push rod. By controlling the telescopic stroke of the first push rod 19, the two movable clamping plates 15 can be driven to move in opposite directions, realizing automatic clamping and loosening of parts. The telescopic stroke of the electric push rod can be precisely preset to adapt to the clamping gap requirements of parts of different sizes, further reducing the risk of part deformation during clamping, and simultaneously adapting to the collaborative operation requirements of automated production lines, improving the overall automation level of the equipment.

[0040] According to one embodiment of the present invention, the clamping mechanism 2 further includes a mating gear 20, which is fixedly connected to the rotating frame 5. The mating gears 20 of the two sets of clamping mechanisms 2 mesh with each other. An adjusting motor is fixedly installed at the bottom of the welding table 1, and the output end of the adjusting motor is fixedly connected to the rotating frame 5 of any set of clamping mechanisms 2. When the adjusting motor is started, the rotating frame 5 drives the corresponding mating gear 20 to rotate. Through gear meshing transmission, the mating gears 20 of the other set of rotating frames 5 are driven to rotate synchronously in the opposite direction, thereby realizing synchronous and reverse rotation of the rotating frames 5 of the two sets of clamping mechanisms 2, which drives the clamped parts to adjust their angle synchronously.

[0041] The gear meshing transmission ensures that the rotation angles of the two sets of rotating frames 5 are completely synchronized, avoiding weld misalignment caused by asynchronous adjustment of the angles of the two sets of parts, and greatly improving the welding and butt joint accuracy; the adjustable motor provides stable driving force, and the rotation angle can be preset to adapt to different welding angle requirements such as butt joint welding and circumferential welding, making operation convenient and highly accurate.

[0042] According to one embodiment of the present invention, the welding assembly 11 includes a first frame 21, a second frame 22 and a welding head 23. The first frame 21 is fixedly disposed on the inner side of the rotating ring 10, the second frame 22 is slidably connected to the first frame 21 along the radial direction of the rotating ring 10, and the welding head 23 is fixedly connected to the second frame 22.

[0043] By adjusting the radial sliding position of the second frame 22, the distance between the welding head 23 and the weld center can be changed to adapt to the weld position requirements of parts with different diameters and specifications. When the rotating ring 10 rotates, it drives the first frame 21, the second frame 22, and the welding head 23 to rotate synchronously around the weld, achieving all-round welding.

[0044] According to one embodiment of the present invention, the welding assembly 11 further includes a second push rod 24, which is fixedly connected to the first frame 21, and the telescopic end of the second push rod 24 is fixedly connected to the second frame 22. The second push rod 24 is an electric push rod.

[0045] By controlling the extension and retraction stroke of the second push rod 24, the second frame 22 can be driven to slide precisely along the radial direction of the rotating ring 10, thereby driving the welding head 23 to move synchronously and adjusting the distance between the welding head 23 and the weld. The extension and retraction stroke of the electric push rod can be preset according to the part specifications to achieve automated and precise positioning of the welding position.

[0046] According to one embodiment of the present invention, the cleaning mechanism 4 further includes a filter screen 25. A negative pressure chamber 26 and a dust collection chamber 27 are provided on the inner side of the collection box 12. A through groove 28 is provided between the negative pressure chamber 26 and the dust collection chamber 27. The fan 13 and the filter screen 25 are both fixedly arranged in the through groove 28. The filter screen 25 is located at one end of the through groove 28 near the dust collection chamber 27, and the fan 13 is located at one end of the through groove 28 near the negative pressure chamber 26. A through hole 29 is provided on the side of the turntable 14. An air outlet and an air inlet are provided on the side of the collection box 12, which are respectively connected to the negative pressure chamber 26 and the dust collection chamber 27. The air outlet and the air inlet are respectively connected to the corresponding through hole 29. After the fan 13 is started, the negative pressure chamber 26 generates negative pressure, which forms an airflow channel through the air outlet and the through hole 29 of the turntable 14. The welding slag generated during welding is sucked into the turntable 14, enters the dust collection chamber 27 through the air inlet, and is filtered by the filter screen 25. The air enters the negative pressure chamber 26 and is discharged through the air outlet, and then enters the rotating ring 10 again. The welding slag settles in the dust collection chamber 27.

[0047] The partitioned design of the negative pressure chamber 26 and the dust collection chamber 27 inside the collection box 12 enables directional guidance of airflow. Combined with the symmetrical arrangement of the turntable 14, it forms an all-round negative pressure adsorption area, improving the collection efficiency of welding slag. The filter screen 25 separates air from welding slag, preventing welding slag from entering the fan 13 and causing equipment damage. This not only ensures the cleanliness of the workshop environment but also protects the health of the operators, meeting the requirements of green production.

[0048] According to one embodiment of the present invention, the cleaning mechanism 4 further includes a dust collection frame 30. The side of the collection box 12 is provided with a slot that communicates with the dust collection chamber 27. The dust collection frame 30 is fitted into the slot, and a sealing strip is embedded at the opening of the slot.

[0049] Welding slag is adsorbed by airflow and settles in the slag collection frame 30. The sealing strip at the slot opening enhances the sealing of the dust collection chamber 27, preventing airflow leakage from affecting the adsorption effect. When the welding slag in the slag collection frame 30 accumulates to a certain amount, the operator can directly pull out the slag collection frame 30 for cleaning. After cleaning, it is inserted back into the slot, and the sealing strip re-seals.

[0050] An automated welding and forming process for automotive parts includes the following steps: Step 1: The operator places the two parts to be welded on the top clamping components 7 of the movable slide 6 of the two sets of symmetrical clamping mechanisms 2, and starts the clamping components 7 to fix the parts firmly; then, the operator controls the movable slide 6 to slide horizontally along the rotating frame 5, and adjusts the docking distance of the two parts according to the preset weld gap requirements, so that the welding surfaces of the parts are initially aligned. Step 2: Drive the rotating frame 5 to rotate relative to the welding table 1, causing the parts to be welded on the clamping assembly 7 to rotate synchronously. Adjust the welding angle of the parts according to the welding requirements until the weld seam of the parts is within the rotating ring 10. Then, the movable slide table 9 on the support frame 8 slides horizontally so that the weld seam is located at the center of the rotating ring 10. Step 3: Drive the rotating ring 10 to rotate, so that the welding assembly 11 rotates around the weld seam to achieve multi-angle and all-round welding; at the same time, the cleaning mechanism 4 is started synchronously, and the fan 13 in the collection box 12 generates negative pressure, which forms a directional airflow through the two symmetrical rotating disks 14 that cooperate with the rotating ring 10 to quickly absorb the welding slag and dust generated during the welding process and guide them into the collection box 12 for centralized collection, so as to avoid welding slag splashing or dust diffusion. Step 4: After the welding operation is completed, the welding assembly 11 stops working and returns to its original position along with the movable slide 9; the clamping assembly 7 releases its fixation on the finished part, the rotating frame 5 and the movable slide 6 return to their initial positions, and the cleaning mechanism 4 continues to run for a preset time to thoroughly clean the welding slag and fumes remaining in the welding area. Step 5: After cleaning is completed, the operator removes the finished part, completing the single welding process. The equipment then awaits the welding of the next batch of parts.

[0051] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.

10. An automated welding and forming process for automotive parts, wherein the welding and forming process employs an automated welding and forming equipment for automotive parts as described in any one of claims 1 to 9, characterized in that, Includes the following steps: Step 1: The operator places the two parts to be welded on the top clamping assembly (7) of the movable slide (6) of the two sets of symmetrical clamping mechanisms (2), and starts the clamping assembly (7) to fix the parts firmly; then, the operator controls the movable slide (6) to slide horizontally along the rotating frame (5), and adjusts the docking distance of the two parts according to the preset weld gap requirements, so that the welding surfaces of the parts are initially aligned. Step 2: By driving the rotating frame (5) to rotate relative to the welding table (1), the parts to be welded on the clamping assembly (7) rotate synchronously. Adjust the welding angle of the parts according to the welding requirements until the weld seam of the parts is inside the rotating ring (10). Then, the movable slide (9) on the support frame (8) slides horizontally so that the weld seam is located at the center of the rotating ring (10). Step 3: Drive the rotating ring (10) to rotate, so that the welding assembly (11) rotates around the weld seam to achieve multi-angle and all-round welding; at the same time, the cleaning mechanism (4) is started synchronously, and the fan (13) in the collection box (12) generates negative pressure. Through the two symmetrical turntables (14) that cooperate with the rotating ring (10) to form a directional airflow, the welding slag and dust generated during the welding process are quickly adsorbed and introduced into the collection box (12) for centralized collection, so as to avoid welding slag splashing or dust diffusion; Step 4: After the welding operation is completed, the welding assembly (11) stops working and resets with the movable slide (9); the clamping assembly (7) releases its fixation on the finished part, the rotating frame (5) and the movable slide (6) return to their initial positions, and the cleaning mechanism (4) runs continuously for a preset time to thoroughly clean the welding slag and fumes remaining in the welding area. Step 5: After cleaning is completed, the operator removes the finished part, completing the single welding process. The equipment then awaits the welding of the next batch of parts.
