Description

Technical Field

[0001] This invention relates to the field of oil pan stamping equipment, and particularly to a stamping equipment for producing automotive oil pans. Background Technology

[0002] Stamping equipment for producing automotive oil pans refers to a complete set of equipment that uses a press as its core, along with specialized stamping dies and an automated system, to form metal sheets into oil pans through processes such as stretching, punching, and shaping.

[0003] In the stamping production of automotive oil pans, traditional manual loading and unloading methods have many shortcomings: the edges of the oil pan sheet are sharp and can easily cut the operator's hands; the workpiece temperature is high after stamping, which can easily cause burns when unloading, posing a significant safety hazard; manual loading is difficult to position quickly and accurately, requiring repeated adjustments, resulting in high labor intensity and low production efficiency; at the same time, residual oil on the workpiece surface can easily drip onto the workshop floor, causing oil waste and increasing the risk of slipping and contaminating the production environment; although existing automated robotic arms can replace manual labor, their complex structure, large space occupation, and high procurement and maintenance costs make them unsuitable for widespread application in small and medium-sized production lines. Therefore, this application provides a stamping equipment for the production of automotive oil pans to meet the needs. Summary of the Invention

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above solution, by setting up auxiliary loading and unloading mechanisms, the auxiliary loading mechanism allows workers to quickly and smoothly transfer the automotive oil pan material plate between the lower and upper dies without direct contact. After transfer, it achieves precise alignment and reliably places the plate on top of the lower die. Compared to the traditional method of manually loading the plate by hand, this structure fundamentally avoids the risk of workers' hands being scratched or cut by the sharp edges and high hardness of the automotive oil pan material plate, significantly improving the safety of the loading process. It also eliminates the tedious operation of repeatedly adjusting, aligning, and correcting the position of the plate manually, greatly reducing the difficulty of alignment and labor intensity. After stamping, the auxiliary unloading mechanism allows the pressed oil pan workpiece to be smoothly removed. The entire process of picking up and transferring the workpiece also does not require direct contact between the worker's hands and the workpiece. On the one hand, this effectively avoids burns caused by the high temperature of the workpiece after stamping, eliminating the safety hazard caused by high temperatures. On the other hand, workers do not need to wear heavy, cumbersome protective gloves throughout the operation, reducing hand strain.

[0018] By incorporating a first connecting frame, connecting bracket, connecting piece, first supporting frame, and first fixing frame within the auxiliary feeding mechanism, not only can non-contact material picking and smooth transfer of oil pan material plates be achieved, preventing the edges of the plates from scratching operators, but also reliable separation and precise alignment of individual plates can be realized, improving feeding efficiency and positioning accuracy.

[0019] By incorporating a connecting block, a second mounting block, and a first clamping plate within the auxiliary feeding mechanism, it is possible to achieve non-contact clamping and removal of the stamped oil pan workpiece, preventing burns to operators from high-temperature workpieces. It also eliminates the need for heavy protective gloves, improving operational flexibility and work comfort.

[0020] By incorporating a second support frame, a second clamping plate, a limiting frame, a baffle, a protrusion, and a recess within the auxiliary feeding mechanism, not only can the oil pan be automatically flipped and residual oil collected in a concentrated manner, preventing oil spills from contaminating the ground and causing personnel to slip, but cutting oil and lubricating oil can also be recycled and reused, reducing production costs and improving the cleanliness and environmental friendliness of the production line.

[0021] In summary, this device can achieve contactless loading and unloading throughout the entire oil pan stamping production process through the cooperation of the auxiliary loading and unloading mechanisms, greatly improving operational safety, production efficiency and positioning accuracy. It can also effectively reduce labor intensity, reduce oil waste, and improve the working environment. In addition, it has the advantages of simple structure, low cost and small space occupation.

[0045] like Figures 1 to 3As shown, an embodiment of the present invention provides a stamping equipment for producing automotive oil pans, including a stamping equipment body 1, a lower die 2 mounted on the stamping equipment body 1, an upper die 3 mounted on the stamping equipment body 1, a first support frame 4 mounted on one side of the stamping equipment body 1, and a second support frame 13 mounted on the other side of the stamping equipment body 1. An automotive oil pan material plate is placed on the top of the first support frame 4; an auxiliary feeding mechanism is used to assist in conveying the automotive oil pan material plate on the top of the first support frame 4 between the lower die 2 and the upper die 3, and the auxiliary feeding mechanism is connected to the first support frame 4; and an auxiliary unloading mechanism is used to press the oil pan material plate between the lower die 2 and the upper die 3. The formed oil pan is removed, and the auxiliary feeding mechanism is connected to the second support frame 13. The main body 1, lower die 2, and upper die 3 of the above-mentioned stamping equipment are all existing mature technologies, and their working principles and specific structures will not be described in detail here. When the device is in use, cutting oil and lubricating oil are required to lubricate and protect the oil pan. In the stamping production process of automotive oil pan material plates, multiple automotive oil pan material plates are first neatly stacked. The top of the first support frame 4 is equipped with a limiting column, which can limit the automotive oil pan material plates to ensure that the plates are stable and neatly arranged in the waiting state, and avoid the subsequent feeding accuracy being affected by the plate offset or skew. Through the auxiliary feeding mechanism, the operator does not need to directly contact the automotive oil pan material. The material plate can be quickly and smoothly transferred between the lower die 2 and the upper die 3, and can be precisely aligned and reliably placed on top of the lower die 2 after transfer. Compared with the traditional method of manually loading the material plate by hand, this structure fundamentally avoids the risk of workers' hands being scratched or cut by the sharp edges and high hardness of the automotive oil pan material plate, significantly improving the safety of the loading process. At the same time, it eliminates the tedious operation of repeatedly adjusting, aligning, and correcting the position by hand, greatly reducing the difficulty of alignment and labor intensity, making the loading action more continuous and efficient, and significantly improving the loading efficiency and alignment accuracy of stamping production. After stamping is completed, with the help of the auxiliary unloading mechanism, the oil pan workpiece formed by compression molding can be smoothly removed. The picking and transferring process also eliminates the need for workers to directly contact the workpieces with their hands. On the one hand, this effectively avoids burns to workers due to the high temperature of the workpieces after stamping, eliminating the safety hazards caused by high temperatures. On the other hand, workers can complete the operation without wearing heavy and cumbersome protective gloves throughout the process, reducing hand burden, improving operational flexibility and comfort, and improving the overall working environment. In summary, this structure, through the cooperation of the auxiliary feeding mechanism and the auxiliary unloading mechanism, achieves continuous and stable stamping production while also possessing advantages such as high safety, simple operation, improved efficiency, low labor intensity, and good working comfort. The specific structure and working principle of the aforementioned auxiliary feeding mechanism and auxiliary unloading mechanism will be described in detail below.

[0046] like Figures 2 to 7As shown, the auxiliary feeding mechanism includes two first guide rails 5 installed on the main body 1 of the stamping equipment. These first guide rails 5 extend along the length of the first support frame 4 and are respectively installed on opposite sides of the top of the first support frame 4 along its width. The two first guide rails 5 are parallel to each other and arranged opposite each other. A first mounting block 6 is installed on the first guide rail 5. A first connecting frame 7 is fixedly connected to the top of the first mounting block 6. A connecting frame 8 is fixedly connected to the side of the first connecting frame 7 away from the first mounting block 6. A connecting piece 9 is fixedly connected to the side of the connecting frame 8 away from the first connecting frame 7. A first support frame 10 is fixedly connected to the side of the connecting piece 9 away from the connecting frame 8. First fixing frames 12 are fixedly connected to the top of both sides of the first guide rail 5. The bottom of the first support frame 4 is connected to the main body 1 of the stamping equipment via a lifting mechanism. The lifting mechanism can adjust the height of the first support frame 4. The lifting mechanism is an existing mature technology, and its working principle and specific structure will not be elaborated here. The top of the first support frame 4 forms the placement surface for the oil pan material plate. The two first guide rails 5 are arranged in parallel, and the first support frame 4 is subjected to lifting... When the lowering mechanism generates movement, the first guide rail 5 and its components remain stationary and do not interfere with each other. The first mounting block 6 and the first connecting frame 7 adopt an integrated structure, resulting in better overall structural stability. Both the first mounting block 6 and the first connecting frame 7 are made of rubber, possessing good elastic deformation capability. The top of the first fixing frame 12 is an inclined structure, and the end of the connecting frame 8 near the first connecting frame 7 is located at the top of the first fixing frame 12 and in contact with it. During operation, the operator holds the two connecting frames 8 with both hands and presses down on the connecting frames 8 and the first connecting frame 7. Under the guidance of the first fixing frame 12, the first connecting frame 7 bends towards the side closer to the first mounting block 6, and the connecting frame 8 undergoes slight deformation under external force, causing it to move towards the first mounting block 6. At the same time, the connecting frame 8 drives the connecting piece 9 to move towards the first mounting block 6. Since the two connecting pieces 9 are respectively located at both ends of the first support frame 10, when the two connecting pieces 9 move away from each other, the first support frame 10 is stretched open by force and tends to move downward.In its extended state, the first support frame 10 first avoids the oil pan material plate closest to it. Upon contacting the top edge of the second oil pan material plate, the operator releases the connecting frame 8. The connecting frame 8 deforms and springs back, clamping the first support frame 10 towards the center of the oil pan material plate. Simultaneously, the connecting frame 8 and the first support frame 10 spring upwards. During this process, the inner contour edge of the first support frame 10 is inserted through the gap between the first and second oil pan material plates, thus smoothly lifting one oil pan material plate. During loading, the lifting mechanism is adjusted to ensure the height of the oil pan material plate closest to the first support frame 10 on the first support frame 4 is just within the first support frame 10. During the downward pressing of the frame 10, it is clamped and lifted. Optionally, a limiting post is set on the first fixing frame 12 to limit the deformation of the first connecting frame 7, further accurately controlling the descent height of the first supporting frame 10, thereby accurately clamping the oil pan material plate closest to the first supporting frame 10. The first connecting frame 7 resets under its own elasticity, thereby driving the connecting frame 8, connecting piece 9 and the first supporting frame 10 to return to their initial state. Thus, during the reset process, the first supporting frame 10 smoothly lifts the single oil pan material plate and limits it to the top of the first supporting frame 10. A positioning protrusion is set on the top of the first supporting frame 10 to limit the oil pan material plate, and during the reset process of each structure, the first supporting frame 10 gradually... The oil pan material plate is clamped to ensure stability. Then, the operator pushes the connecting frame 8, causing the first mounting block 6 to move along the first guide rail 5. This, in turn, allows the first support frame 10 to transport the oil pan material plate towards the lower mold 2. Once the plate reaches the designated position, the operator presses the connecting frame 8 again. Guided and limited by the first fixing frame 12 on that side, the first support frame 10 opens, allowing the oil pan material plate to fall onto the lower mold 2. With the assistance of the positioning pins on the lower mold 2, the oil pan material plate is precisely positioned and placed. After loading one oil pan material plate, the first mounting block 6 and its components are moved back to their initial positions to prepare for the next loading. The coordinated use of these various structures not only enables contactless picking, transferring, and precise loading of oil pan material plates, avoiding safety hazards such as scratches and cuts caused by direct hand contact with the plate edges, but also achieves reliable separation and stable conveying of individual plates through guiding, deformation, resetting, and positioning. Furthermore, the entire loading process is simple and fluid, eliminating the need for repeated plate adjustments by workers, significantly reducing labor intensity and operational difficulty, greatly improving loading efficiency and alignment accuracy. This ensures that the oil pan material plates can be quickly, stably, and accurately placed on the lower die 2, providing a stable and reliable loading foundation for subsequent stamping processes, and further enhancing the safety, continuity, and production efficiency of the overall stamping production line.

[0047] Furthermore, a first weakening part 11 is provided on the side of the first support frame 10 away from the connecting piece 9, making the first support frame 10 more prone to deformation under external force. The shape of the first support frame 10 is adapted to the shape of the automotive oil pan material plate, enabling the first support frame 10 to stably lift and transport the oil pan material plate. The outer edge of the first support frame 10 is arc-shaped to prevent it from scratching the surface of the oil pan material plate. The connecting piece 9 and the first support frame 10 are integrally formed, which provides good stability and facilitates production and use. The connecting piece 9 is an arc-shaped structure that protrudes upwards, making it convenient for workers to operate the connecting frame 8. The first connecting frame 7 has a third weakening part 44 at its top, which prevents the first connecting frame 7 from accidentally scratching the staff. This allows the first connecting frame 7 to deform preferentially from the third weakening part 44 when subjected to external force, and improves the deformation capacity of the first connecting frame 7. The top and bottom of the first mounting block 6 are fixedly connected to the third slider 42. The top and bottom of the first guide rail 5 are provided with the third groove 43 that matches the shape of the third slider 42. The cross-section of the first mounting block 6 is C-shaped. The third slider 42 is stably installed in the third groove 43, so that the first mounting block 6 can move along the first guide rail 5 and remain stable, and will not fall off accidentally.

[0048] like Figure 2 , Figure 3 and Figures 8 to 14As shown, the auxiliary feeding mechanism includes two second guide rails 14 mounted on the second support frame 13, extending along the length of the second support frame 13 and respectively mounted on opposite sides of the top of the second support frame 13 along the width direction. The two second guide rails 14 are parallel to each other and arranged opposite each other. A connecting block 16 is fixedly connected to the side of the second guide rail 14 away from the second support frame 13, and a movable block 17 is slidably connected to the side of the connecting block 16 away from the second guide rail 14. A second mounting block 19 is mounted on the movable block 17, and a second connecting frame 21 is fixedly connected to the top of the second mounting block 19. A third connecting frame 22 is rotatably connected to the side of the frame 21 away from the second mounting block 19. A first clamping piece 25 is fixedly connected to the side of the third connecting frame 22 away from the second connecting frame 21. A connecting rod 41 is installed between the two third connecting frames 22. The bottom of the second support frame 13 is fixedly connected to the main body 1 of the stamping equipment. Two second guide rails 14 are arranged in parallel. The connecting block 16 is perpendicular to the second guide rails 14. The second guide rails 14 and the connecting block 16 are an integral structure. The movable block 17 is adapted to the shape of the second guide rail 14. The shape of the second mounting block 19 is the same as that of the first mounting block 6. The second mounting block 19 and the second connecting frame 21 are... The system is a single unit, with the third connecting frame 22 and the first clamping piece 25 forming a single unit. The shape of the first clamping piece 25 is adapted to the shape of the oil pan material plate. The connecting rod 41 is used to connect the two third connecting frames 22 together. The connecting rod 41 is made of plastic and has a bent part in the middle, making it easy to deform and bend under stress. After the oil pan material plate is stamped into an oil pan by the stamping equipment body 1, lower die 2, and upper die 3, the second mounting block 19 is first moved along the guide rail 14, so that the second mounting block 19 moves closer to the lower die 2. When the second mounting block 19 moves to the top of the movable block 17, the movable block 17 is then moved closer to the lower die 2. Block 17 and the second mounting block 19 move downwards together along the guide of the connecting block 16. Then, the worker pulls the connecting rod 41 to deform and unfold, so that the two first clamping plates 25 move away from each other to avoid the oil pan. After the first clamping plates 25 are aligned with the oil pan, the oil pan is clamped by the first clamping plates 25. Then, the second mounting block 19 moves in the opposite direction, so that the oil pan can be smoothly moved out between the lower mold 2 and the upper mold 3. The entire process does not require the worker to directly contact the oil pan. This can not only effectively prevent the worker from being burned by the oil pan with a high temperature after stamping, but also eliminate the safety hazards caused by high temperature workpieces. At the same time, the unloading operation can be completed without wearing heavy protective gloves.

[0049] Furthermore, the second guide rail 14 and the movable block 17 are both provided with first grooves 15 at their top and bottom. The second mounting block 19 is fixedly connected to the top and bottom with first sliders 20 that are adapted to the shape of the first grooves 15. When the second mounting block 19 moves, the first sliders 20 move within the first grooves 15, ensuring the stability of the second mounting block 19. The connecting block 16 is provided with a second groove 27 on the side near the movable block 17. The movable block 17 is fixedly connected to the side near the connecting block 16 with a second slider 28 that is adapted to the shape of the second groove 27. When the second mounting block 19 and the movable block 17 move along the connecting block 16, the second slider 28 moves within the second groove 27, further ensuring the movement of the second mounting block 19. To ensure stability, buffer cavities 29 are provided on both sides of the second slider 28. The second slider 28 is made of rubber, allowing it to deform under pressure, facilitating smoother movement. Furthermore, the elastic deformation of the second slider 28 under no external force allows its outer wall to fit tightly against the inner wall of the second groove 27, thus maintaining the stability of the movable block 17. A limiting piece 30 is fixedly connected to the top of the connecting block 16. An obstacle groove 18, matching the shape of the limiting piece 30, is provided on the top of the movable block 17. The bottom of the second groove 27 is closed, while the top is open. The cooperation of the obstacle groove 18 and the limiting piece 30 limits the maximum position of the movable block 17's movement towards its top, thereby... The holes on the movable block 17 and the second guide rail 14 can be quickly aligned, allowing the second mounting block 19 to move from the movable block 17 to the second guide rail 14. A rotating shaft 23 is installed on the side of the second connecting frame 21 and the third connecting frame 22 that are close to each other. The second connecting frame 21 and the third connecting frame 22 are rotatably connected by the rotating shaft 23. A limiting block 24 is installed on the rotating shaft 23. Specifically, one limiting block 24 should be installed on the rotating shaft 23, and two limiting blocks 24 should be installed on the other rotating shaft 23. The mutual limiting effect of the three limiting blocks 24 limits the maximum rotation angle of the rotating shaft 23, thereby preventing the first clamping piece 25 and the oil pan clamped on it from rotating too far. The top of the second connecting frame 21... A second weakening part 32 is provided, so that the second connecting frame 21 deforms first from the second weakening part 32 under the action of external force, and the deformation capacity of the second connecting frame 21 is better. The top of the second guide rail 14 is fixedly connected to the second fixing frame 31. The top of the two second fixing frames 31 is V-shaped, and the side closer to the lower mold 2 is wider. The second fixing frame 31 plays a limiting role for the second connecting frame 21. As the second connecting frame 21 moves further away from the lower mold 2, the first clamping piece 25 clamps the oil pan more tightly, thereby ensuring stable transportation. The side of the first clamping piece 25 away from the second guide rail 14 is provided with a guide part 26. The guide part 26 is used to guide the first clamping piece 25 to quickly clamp the edge of the oil pan.

[0050] like Figure 8 , Figures 10 to 13As shown, a collection box 33 is installed at the bottom of the second support frame 13 to collect oil spills during the oil pan extraction process. A second support frame 34 is fixedly connected to the top of the collection box 33 on the side away from the second support frame 13. A second clamping piece 35 is fixedly connected to the side of the second support frame 34 away from the collection box 33. The second support frame 34 is made of plastic and the second clamping piece 35 is an integral part of it. As the first clamping piece 25 moves the oil pan closer to the second clamping piece 35, the second clamping piece 35 gradually approaches the oil pan and moves one edge of it closer to the oil pan. Clamping; as the first clamping piece 25 continues to move the oil pan, the second support frame 34 deforms accordingly until the second clamping piece 35 is nearly rotated more than 90°, at which point the second clamping piece 35 disengages from the edge of the oil pan; at this point, the oil pan achieves a rotation of slightly more than 90° under the combined action of the second support frame 34 and the second clamping piece 35. During this process, residual oil on both the inner and outer surfaces of the oil pan can drip smoothly into the collection box 33 without splashing or falling to the ground, thus achieving centralized collection and recycling of residual oil on the oil pan. To avoid oil pollution of the working environment and safety hazards such as slippery ground, this system can effectively recover cutting oil or lubricating oil, reduce oil waste, lower production costs, and further improve the cleanliness and environmental friendliness of the production line. A limiting frame 36 is fixedly connected to the top of the second support frame 13. A baffle 37 is provided on the top of the limiting frame 36. A protrusion 38 is provided on the side of the limiting frame 36 near the second support frame 34, and a recess 39 is provided on the side of the limiting frame 36 near the baffle 37. Lightweight grooves 40 are equidistantly opened on the limiting frame 36, which can provide support for the second support frame 13. The skeleton 34 provides clearance and reduces its own weight, while facilitating the oil droplets to fall into the collection box 33. The limiting skeleton 36 and the baffle 37 are integrally formed. When the oil pan moves with the mechanism to the point where it is about to detach from the first clamping plate 25, the oil pan first contacts the protrusion 38. Under the guiding and limiting action of the protrusion 38, the movement trajectory of the oil pan changes abruptly and generates a slight oscillation. This oscillation can further shake off the residual oil inside the oil pan. During the process of the oil pan passing through the protrusion 38, the clamping structure undergoes slight deformation, and the oil pan maintains a stable clamping state throughout the entire movement.When one side of the oil pan moves to the recess 39, the rotation angle of the oil pan is greater than 90 degrees, and its top surface is in close contact with the side of the baffle 37 near the protrusion 38. At this time, the second clamping piece 35 disengages from the oil pan, releasing the clamping effect of the first clamping piece 25 on the oil pan. Finally, the operator can remove the oil pan placed on the limiting frame 36 and the baffle 37 using a special clamping tool or wearing gloves. The combined use of the above structures can not only achieve effective cleaning of residual oil stains inside the oil pan while completing the automatic unloading of the oil pan, improving the cleanliness of the oil pan output, but also reliably limit and stably support the oil pan during the transfer, flipping and unloading process, ensuring that the workpiece posture is regular and the unloading is smooth, further improving the automation level and operational safety of the entire stamping production line.

[0051] Furthermore, optionally, in this technical solution, some of the deformable and bendable parts are easily damaged and replaceable components. Since the service life of the components is related to the selected materials, the environment in which they are used, and the number of times they are used, any component has a certain service life, which has been set during the design. Therefore, if the deformable and bendable parts are damaged during use, they need to be replaced periodically. The installation, disassembly, and replacement of the deformable and bendable parts are existing mature technologies, and will not be elaborated on here.

[0052] The working principle of the technical solution provided by this invention is as follows:

[0053] In use, the material is first loaded. The operator holds the two connecting frames 8 with both hands and presses them down onto the first connecting frame 7. Under the guidance of the first fixing frame 12, the first connecting frame 7 bends and deforms towards the side closer to the first mounting block 6, causing the connecting frame 8 and the connecting piece 9 to move together toward the first mounting block 6. The two connecting pieces 9 are respectively located at both ends of the first support frame 10. When the two connecting pieces 9 move away from each other, the first support frame 10 is stretched open and tends to move downward, thus avoiding the oil pan material plate. After the first support frame 10 contacts the oil pan material plate, the operator releases the connecting frame 8. The first connecting frame 7 returns to its original position under its own elasticity, causing the connecting frame 8, the connecting piece 9, and the first support frame 10 to move together. The system restores to its initial state. During the reset process, the first support frame 10 smoothly lifts and limits the single oil pan material plate to its top. The top of the first support frame 10 is equipped with a positioning protrusion. Subsequently, the operator pushes the connecting frame 8, causing the first mounting block 6 to move along the first guide rail 5. The first support frame 10 then drives the oil pan material plate to be conveyed to the lower mold 2. After moving to the designated position, the connecting frame 8 is pressed again. Under the guidance of the first fixing frame 12 on this side, the first support frame 10 opens, and the oil pan material plate falls onto the lower mold 2. Under the guidance of the positioning pin on the lower mold 2, it is accurately positioned and placed. After completing a single loading, the first mounting block 6 and its components are reset to prepare for the next loading. The bottom of the first support frame 4 passes through... The lifting mechanism is connected to the main body 1 of the stamping equipment. The lifting mechanism can adjust the height of the first support frame 4 to adapt to different working conditions. After the oil pan material plate is placed stably and accurately on the top of the lower die 2, it is stamped between the lower die 2 and the upper die 3. After stamping, the stamped oil pan workpiece is smoothly removed with the help of the auxiliary unloading mechanism. First, the second mounting block 19 is moved to the top of the movable block 17, and then the movable block 17 and the second mounting block 19 are moved downward along the guide of the connecting block 16, so that the two first clamping pieces 25 are separated from each other to avoid the oil pan. After the first clamping pieces 25 are aligned with the oil pan, the oil pan is clamped by the first clamping pieces 25, and then the second mounting block 19 is driven to move in the opposite direction, so that the oil pan is smoothly removed from between the lower die 2 and the upper die 3. Picking up the part; as the first clamping piece 25 moves the oil pan closer to the second clamping piece 35, the second clamping piece 35 gradually approaches the oil pan and clamps one edge of it; as the first clamping piece 25 continues to move, the second support frame 34 deforms accordingly until the second support frame 34 deforms to the point where the second clamping piece 35 is close to a position where it has rotated more than 90°, and the second clamping piece 35 disengages from the edge of the oil pan; at this time, the oil pan achieves a flip of slightly more than 90° under the combined action of the second support frame 34 and the second clamping piece 35, and the residual oil on both the inner and outer surfaces of the oil pan drips smoothly into the collection box 33, realizing the centralized collection and recycling of oil, avoiding pollution of the working environment and causing the ground to become slippery, while reducing oil waste, lowering production costs, and improving the cleanliness and environmental friendliness of the production line;As the oil pan moves with the mechanism and is about to disengage from the first clamp 25, it first contacts the protrusion 38. Under the guiding and limiting action of the protrusion 38, the oil pan's movement trajectory changes abruptly and produces slight oscillations, further shaking off residual oil. As the oil pan passes the protrusion 38, the clamping structure undergoes slight deformation and maintains a stable clamping state throughout. When one side of the oil pan moves to the recess 39, its rotation angle is greater than 90 degrees, and its top surface adheres tightly to the side of the baffle 37 closest to the protrusion 38. At this point, the second clamp 35 disengages from the oil pan, releasing the clamping effect of the first clamp 25. Finally, the oil pan, placed on the limiting frame 36 and the baffle 37, is removed by the operator using a special clamping tool or while wearing gloves.
