Description

Technical Field

[0001] This invention relates to the field of automotive parts manufacturing technology, and in particular to an oil pan processing production line. Background Technology

[0002] The processing of oil pans typically involves die casting, drilling, and rolling. Manufacturers use laser marking to mark the oil pans. By using the QR code on each oil pan, manufacturers can record and trace the oil pans and calculate the pass rate of a batch of oil pans. A low pass rate will affect production costs.

[0003] In the current technology, the main problems in oil pan machining are in the drilling and rolling steps. These two steps require maintaining the stability of the oil pan. However, due to the irregular shape of the oil pan, it is easy for deviations to occur during these two steps. In the production of oil pans with high precision requirements, such deviations can easily lead to a low pass rate. Summary of the Invention

[0004] To address the problem of machining deviations caused by the irregular shape of oil pans during drilling and grinding processes in the prior art, this application provides an oil pan machining production line, the specific solution of which is as follows.

[0005] An oil pan processing production line includes a marking component and a processing component. The marking component is used to mark the oil pan. The processing component includes a processing table, on which a limiting mold and a processing cutter are provided. The processing cutter is movable in both horizontal and vertical directions. The limiting mold includes a limiting seat, on which multiple support rods are provided. The support rods are shaped to correspond to the oil pan and are used to abut against the oil pan. The limiting seat also includes multiple detection columns, which are shaped to correspond to the oil pan and are used to abut against the oil pan. Each detection column has a detection air passage, which is completely blocked by the oil pan. An airtightness detection element is provided inside the detection air passage, which is used to obtain the airtightness between the detection air passage and the oil pan. A micro-adjustment column is provided inside the support rod corresponding to the oil pan. The micro-adjustment column is slidably connected inside the support rod and can move along the vertical direction of the support rod. The micro-adjustment column can abut against the oil pan.

[0006] By adopting the above technical solutions, the marking component can mark the oil pan, the processing head can move horizontally and vertically to process the oil pan, the support rod and detection column of the limiting mold can abut against the oil pan, and the detection air passage on the detection column cooperates with the airtightness detection component to obtain the airtightness between the detection air passage and the oil pan. When the oil pan is tightly attached to the detection column, the airtightness is good, while when there is a gap between the oil pan and the detection column, the airtightness is poor. This can be used to determine whether the oil pan is placed stably. The micro-adjustment column can move vertically along the support rod and abut against the oil pan, allowing for fine-tuning according to the actual situation of the oil pan, better aligning the oil pan and improving the accuracy of processing.

[0007] Optionally, the airtightness detection device includes a vacuum pump and a flow meter. The vacuum pump is connected to the flow meter, the vacuum pump is used to draw gas into the flow meter, and the flow meter is used to display the gas flow rate.

[0008] By adopting the above technical solution, the air pump can effectively extract gas, and the gas flow rate extracted by the air pump can be detected by the flow meter. The air tightness can be judged by the gas flow rate displayed by the flow meter, which is more intuitive to observe.

[0009] Optionally, the detection column includes a bottom detection column and an edge detection column. The bottom detection column is fixedly mounted on the limiting seat and is located at the bottom of the oil pan. The edge detection column is located at the edge of the oil pan.

[0010] By adopting the above technical solution, the bottom detection column corresponds to the bottom of the oil pan, and the edge detection column corresponds to the edge of the oil pan, which can achieve different clamping and restriction for different positions, further improving the stability of clamping the oil pan.

[0011] Optionally, the limiting seat is provided with a pad, and the pad is provided with a clamping claw, which can cooperate with the detection column to clamp the edge of the oil pan.

[0012] By adopting the above technical solution, since the edge of the oil pan is relatively thin, the clamping method can effectively fix the edge of the oil pan. The pad can raise the clamping jaws, and the height provided by the pad for the clamping jaws can enable the clamping jaws to effectively clamp the edge of the oil pan.

[0013] Optionally, the limiting seat is also provided with a positioning claw, which is used to abut against the side wall of the oil pan.

[0014] By adopting the above technical solution, the positioning gripper clamps the oil pan by squeezing it from multiple directions toward the center, thereby achieving positioning and making the oil pan more stable.

[0015] Optionally, a pressure sensor is also provided on the detection column. The pressure sensor does not interfere with the detection air passage. The pressure sensor can detect the pressure of the clamping jaws pressing against the oil pan.

[0016] By adopting the above technical solutions, the pressure sensor can detect the force pressing the oil pan, reducing the situation where the oil pan is subjected to excessive pressure, and further improving the stability when processing the oil pan.

[0017] Optionally, a driving air pipe is provided inside the support rod corresponding to the micro-adjustment column, and an exhaust hole is provided on the side wall of the support rod. The driving air pipe is used to pass gas to drive the micro-adjustment column to move up and down. When the driving air pipe moves upward, the gas can be discharged from the exhaust hole.

[0018] By adopting the above technical solution, a drive air pipe is installed inside the support rod, which can drive the micro-adjustment column to move up and down, so that the oil pan can move slightly and be more accurately aligned with the limiting mold. When the drive air pipe moves upward, the gas is discharged from the exhaust hole, which can avoid the situation where some gas remains after adjustment and cannot be discharged, causing the micro-adjustment column to be continuously subjected to upward force, thus affecting the stability of the oil pan.

[0019] Optionally, the driving air pipe is connected to the suction pump, and a control valve is provided between the driving air pipe and the suction pump. The control valve can control the opening and closing of the driving air pipe and the suction pump. The control valve is electrically connected to a flow meter. When the detection air passage is connected to the outside, the flow meter causes the control valve to open. When the detection air passage is isolated from the outside, the flow meter causes the control valve to close.

[0020] By adopting the above technical solution, when poor air tightness is detected, the gas can drive the micro-adjustment rod to move up and down, thereby realizing the micro-adjustment of the oil pan. After the air tightness is improved after the adjustment is completed, the adjustment of the oil pan can be stopped. At this time, it is determined that the oil pan is placed accurately, and processing can be carried out, so that the oil pan can be processed more stably and accurately.

[0021] Optionally, the control valve is electrically connected to the clamping jaws; when the control valve is opened, the clamping jaws are released, and when the control valve is closed, the clamping jaws are clamped.

[0022] By adopting the above technical solution, the clamping jaws are released when the adjustment is not completed, avoiding the situation where the oil pan is fixed and cannot be adjusted. After the adjustment is completed, the clamping jaws can immediately clamp the oil pan, thereby further improving the accuracy of processing.

[0023] In summary, this application has at least the following beneficial effects: This application solves the problem in the prior art where the irregular shape of the oil pan easily leads to displacement and machining deviation during drilling and rolling. This application detects and adjusts the placement of the oil pan to make the oil pan more accurately machined, thereby reducing the occurrence of defective products. Attached Figure Description

[0029] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] An oil pan processing production line, such as Figure 1 and Figure 2 As shown, the system includes a marking component 1 and a processing component 2. The marking component 1 is used to mark the oil pan. The processing component 2 includes a processing table 21, on which a limiting mold 3 and a processing cutter head 211 are mounted. The processing cutter head 211 can move in both horizontal and vertical directions. In specific implementation, the marking component 1 uses a laser marking machine to mark the oil pan with a QR code, allowing traceability of the oil pan by scanning the QR code. The processing cutter head 211 can be equipped with various cutting tools to perform various processing operations on the oil pan, such as grinding and drilling. Simultaneously, the processing cutter head 211 is equipped with a corresponding linear mechanism, enabling it to move in either the vertical or horizontal direction.

[0031] like Figure 1 and Figure 2As shown, the limiting mold 3 includes a limiting seat 31, on which multiple support rods 32 are provided. The support rods 32 are shaped to correspond to the oil pan and are used to abut against the oil pan. The limiting seat 31 also includes multiple detection columns 33, which are shaped to correspond to the oil pan and are used to abut against the oil pan. Detection air passages 331 are opened on the detection columns 33. The oil pan can completely cover the detection air passages 331. An airtightness detection element is provided inside the detection air passages 331. The airtightness detection element is used to obtain the airtightness between the detection air passages 331 and the oil pan. The airtightness detection element includes a vacuum pump 34 and a flow meter 35. The vacuum pump 34 is connected to the flow meter 35. The vacuum pump 34 is used to draw gas into the flow meter 35, and the flow meter 35 is used to display the gas flow rate. In practice, the shape and arrangement of the support rod 32 and the detection column 33 can guide the oil pan, and multiple sets of support rods 32 and detection columns 33 are provided. The detection rod is used for both detection and support of the oil pan, so that the oil pan is placed accurately. After the oil pan is placed accurately, the machining head 211 can process the oil pan according to the set data. The accuracy of the placement can be judged by the air tightness test. When the air tightness is good, it proves that the oil pan is tightly attached to the support rod 32 and the detection column 33. At this time, the oil pan can be processed more accurately.

[0032] like Figure 1 and Figure 2 As shown, the detection column 33 includes a bottom detection column 332 and an edge detection column 333. The bottom detection column 332 is fixedly mounted on the limiting seat 31, corresponding to the bottom of the oil pan, while the edge detection column 333 corresponds to the edge of the oil pan. A pad 36 is provided on the limiting seat 31, and a clamping jaw 361 is provided on the pad 36. The clamping jaw 361 can cooperate with the detection column 33 to clamp the edge of the oil pan. In specific implementation, the edge of the oil pan is relatively thin and can be clamped by the clamping jaw 361 and the edge detection column 333. After clamping, the stability during processing can be further improved, reducing the possibility of the processing head 211 moving the oil pan and affecting the processing quality.

[0033] like Figure 1 and Figure 2 As shown, the limiting seat 31 is also equipped with a positioning gripper 37, which is used to abut against the side wall of the oil pan. A pressure sensor is also provided on the detection column 33. The pressure sensor and the detection air passage 331 do not interfere with each other. The pressure sensor can detect the pressure of the gripper 361 pressing against the oil pan. In specific implementation, the positioning gripper 37 moves corresponding to the side wall of the oil pan. The gripping of the positioning gripper 37 relies on simultaneous pushing towards the center of the oil pan from multiple directions. The pressure sensor is electrically connected to the positioning gripper 37 to detect and adjust the gripping force, preventing damage to the oil pan.

[0034] like Figure 3 and Figure 4 As shown, a micro-adjustment column 321 is provided inside the support rod 32 corresponding to the oil pan. The micro-adjustment column 321 is slidably connected inside the support rod 32 and can move along the vertical direction of the support rod 32. The micro-adjustment column 321 can abut against the oil pan. A drive air pipe 322 is provided inside the support rod 32 corresponding to the micro-adjustment column 321. An exhaust hole 323 is provided on the side wall of the support rod 32. The drive air pipe 322 is used to drive the micro-adjustment column 321 to move up and down by passing gas. When the drive air pipe 322 moves upward, the gas can be discharged from the exhaust hole 323. In specific implementation, the movable range of the micro-adjustment column 321 is limited to a small range by a specific shape. By frequently micro-moving the oil pan, the oil pan is slowly adjusted so that the oil pan is adjusted to an accurate position under guidance. The drive air pipe 322 needs to be connected to gas to drive the micro-adjustment column. In other embodiments, the micro-adjustment rod can also be driven by a cam structure, which can reduce the situation where the gas volume is insufficient to drive the rod.

[0035] like Figure 3 and Figure 4 As shown, the drive air pipe 322 is connected to the suction pump 34. A control valve 324 is installed between the drive air pipe 322 and the suction pump 34. The control valve 324 can control the opening and closing of the drive air pipe 322 and the suction pump 34. The control valve 324 is electrically connected to the flow meter 35. When the detection air passage 331 is connected to the outside, the flow meter 35 causes the control valve 324 to open; when the detection air passage 331 is isolated from the outside, the flow meter 35 causes the control valve 324 to close. The control valve 324 is electrically connected to the clamping jaw 361. When the control valve 324 is open, the clamping jaw 361 is released; when the control valve 324 is closed, the clamping jaw 361 is clamped. In specific implementation, when poor air tightness is detected, the gas can drive the micro-adjustment rod to move up and down, thereby realizing micro-adjustment of the oil pan. After the adjustment is completed and the air tightness is improved, the adjustment of the oil pan can be stopped. At this time, it is determined that the oil pan is placed accurately, and processing can be carried out, thereby effectively improving the accuracy of processing.

[0036] Working principle: By detecting the placement of the oil pan and automatically adjusting it, the oil pan can be processed more accurately, thereby reducing the probability of defective products.

[0037] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
