Description

Technical Field

[0001] This utility model relates to the field of motorcycle crankcase manufacturing technology, and in particular to a dual-station pressure plugging and leak detection device and processing system. Background Technology

[0002] The crankcase of a motorcycle engine is one of its core components. Some crankcases consist of two parts: a left crankcase and a right crankcase, connected by bolts to form a closed space that supports the crankshaft and holds the engine oil. The closed space formed by the interconnected left and right crankcases needs sufficient sealing performance to prevent oil leakage, withstand high-pressure gases within the crankcase, and prevent the ingress of external debris. Therefore, during crankcase production, after the plugging and pressing process of the left and right crankcases, leak testing is required for both to detect leaks promptly and improve product quality. Currently, leak testing of the left and right crankcases in motorcycles mostly uses water-based sealing methods, requiring separate testing for each crankcase, which is inefficient.

[0041] Reference Figures 1 to 4This utility model provides a dual-station pressure plugging leak detection device, including a machine base 100, a first sealing mechanism, and a second sealing mechanism. The machine base 100 includes a platform body 120. The first sealing mechanism includes a first worktable 200 and a first sealing component 300. The first worktable 200 is disposed on the machine base 100, and the first sealing component 300 is disposed above the first worktable 200. The first worktable 200 is provided with a first vent hole 210. The second sealing mechanism includes a second worktable 400 and a second sealing component 500. The second worktable 400 is disposed on the machine base 100, and the second sealing component 500 is disposed above the second worktable 400. The second worktable 400 is provided with a second vent hole 410. Specifically, both the first worktable 200 and the second worktable 400 are disposed on the platform body 120. The first worktable 200 can accommodate the left crankshaft housing 700, and the second worktable 400... The system can accommodate a right crankshaft housing 800. A first sealing assembly 300 seals the left crankshaft housing 700 for leak testing, and a second sealing assembly 500 seals the right crankshaft housing 800 for leak testing. Specifically, a first testing station is formed between the first worktable 200 and the first sealing assembly 300 for leak testing of the left crankshaft housing 700, and a second testing station is formed between the second worktable 400 and the second sealing assembly 500 for leak testing of the right crankshaft housing 800. The testing mechanism 600 connects a first vent 210 and a second vent 410 via a pipe. Specifically, the testing mechanism 600 is connected to an external high-pressure air source. The testing mechanism 600 can control the connection or disconnection between the external high-pressure air source and the first vent 210 and the second vent 410. The testing mechanism 600 can also detect the gas pressure of the first vent 210 and the second vent 410.

[0042] The left crankshaft housing 700 is placed on the first worktable 200, and the right crankshaft housing 800 is placed on the second worktable 400. The first sealing assembly 300 and the second sealing assembly 500 are then used to seal the left crankshaft housing 700 and the right crankshaft housing 800 respectively. Air is then vented through the detection mechanism 600, the first vent 210, and the second vent 410 to detect leaks in both housings. This system can perform leak detection on either the left crankshaft housing 700 or the right crankshaft housing 800 individually or simultaneously, improving leak detection efficiency. Furthermore, the same leak detection device can be used to detect leaks in both crankshaft housings, allowing a single operator to work simultaneously, saving labor costs and reducing floor space requirements. Using high-pressure gas to perform leak detection on the left crankshaft housing 700 and the right crankshaft housing 800 is faster than water-based leak testing. It also prevents the left crankshaft housing 700 or the right crankshaft housing 800 from getting wet, improving product cleanliness and eliminating the need for wiping or drying after water-based leak testing, thus further improving work efficiency.

[0043] According to some embodiments of this application, refer to Figure 1 , Figure 2 , Figure 4 The first sealing assembly 300 includes a first sealing ring 310 and a first sealing block 320. The first sealing ring 310 is mounted on the top surface of the first worktable 200, and the first sealing block 320 is movably disposed above the first sealing ring 310. Specifically, the structure of the first sealing ring 310 matches the lower inner edge of the left crankshaft housing 700 to achieve positioning and sealing of the left crankshaft housing 700. Specifically, the lower structure of the first sealing block 320 matches the upper side of the left crankshaft housing 700. The first sealing block 320 can move up and down. When the first worktable 200 is placed on the left crankshaft housing 700, the first sealing block 320 can move downwards to seal the holes on the upper side of the left crankshaft housing 700. By using the first sealing ring 310 and the first sealing block 320 to seal the lower and upper sides of the left crankshaft housing 700 respectively, the sealing effect of the left crankshaft housing 700 is improved.

[0044] Further, the machine tool 100 includes a frame 110, and the first sealing assembly 300 includes a first drive module 330 and a first connecting plate 340. The first drive module 330 is mounted on the frame 110, the first connecting plate 340 is fixedly connected to the output end of the first drive module 330, and the first sealing block 320 is fixedly connected to the lower side of the first connecting plate 340. Specifically, the first drive module 330 includes a first drive cylinder 331 and a first solenoid valve 332. The first solenoid valve 332 is mounted on the air inlet end of the first drive cylinder 331 and is used to control the connection or disconnection between the first drive cylinder 331 and the external air source. Specifically, the first drive cylinder 331 can drive its output end to move up and down, thereby driving the first connecting plate 340 and the first sealing block 320 to move up and down, so as to move the first sealing block 320 downward and seal the hole on the upper side of the left crankshaft housing 700.

[0045] Furthermore, the first sealing assembly 300 also includes a plurality of first guide posts 350, which are fixedly connected to the lower side of the first connecting plate 340. A plurality of first guide cylinders 220 are provided on the first worktable 200, and the plurality of first guide posts 350 and the plurality of first guide cylinders 220 are compatiblely connected. Specifically, refer to... Figure 1 , Figure 2 , Figure 4 The lower ends of the multiple first guide posts 350 are provided with conical guide structures. When the first drive cylinder 331 drives the first connecting plate 340 and the first sealing block 320 to move downward, the multiple first guide posts 350 move downward together. The conical guide structures provided at the lower ends of the first guide posts 350 guide and adjust the position of the first guide posts 350 as they enter the first guide cylinder 220, thereby achieving the horizontal adjustment of the position of the first connecting plate 340 and the first sealing block 320 connected to the first guide posts 350.

[0046] According to some embodiments of this application, refer to Figure 1 , Figure 2 , Figure 4The second sealing assembly 500 includes a second sealing ring 510 and a second sealing block 520. The second sealing ring 510 is mounted on the top surface of the second worktable 400, and the second sealing block 520 is movably disposed above the second sealing ring 510. Specifically, the structure of the second sealing ring 510 matches the lower inner edge of the right crankshaft housing 800 to achieve positioning and sealing of the right crankshaft housing 800. Specifically, the lower structure of the second sealing block 520 matches the upper side of the right crankshaft housing 800. The second sealing block 520 can move up and down. When the second worktable 400 is placed on the right crankshaft housing 800, the second sealing block 520 can move downwards to seal the holes on the upper side of the right crankshaft housing 800. By using the second sealing ring 510 and the second sealing block 520 to seal the lower and upper sides of the right crankshaft housing 800 respectively, the sealing effect of the right crankshaft housing 800 is improved.

[0047] Furthermore, referring to Figure 3 A third vent 521 is provided on the lower side of the second sealing block 520, and the third vent 521 is connected to the detection mechanism 600 through a pipe. Specifically, the third vent 521 is used to fill the oil passage cavity on the upper side of the right crankshaft housing 800 with high-pressure gas, and the detection mechanism 600 detects the gas pressure of the third vent 521, thereby realizing the leak detection of the oil passage cavity on the upper side of the right crankshaft housing 800.

[0048] As a preferred option, refer to Figure 3 A third sealing ring 522 and a sealing strip 523 are also provided on the lower side of the second sealing block 520, and a third vent hole 521 is provided through the sealing strip 523. The third sealing ring 522 is used to seal the upper circular hole of the right crankshaft housing 800, and the sealing strip 523 is used to seal the oil passage cavity on the upper side of the right crankshaft housing 800.

[0049] It is understood that in some other embodiments, a sealing ring is also provided on the lower side of the first sealing block 320, and the sealing ring is used to seal the upper circular hole of the left crankshaft housing 700.

[0050] Furthermore, referring to Figure 1 , Figure 2 , Figure 4The machine tool 100 includes a frame 110. The second sealing assembly 500 includes a second drive module 530 and a second connecting plate 540. The second drive module 530 is mounted on the frame 110, and the second connecting plate 540 is fixedly connected to the output end of the second drive module 530. The second sealing block 520 is fixedly connected to the lower side of the second connecting plate 540. Specifically, the second drive module 530 includes a second drive cylinder 531 and a second solenoid valve 532. The second solenoid valve 532 is mounted on the air inlet end of the second drive cylinder 531 and is used to control the connection or disconnection between the second drive cylinder 531 and an external air source. Specifically, the second drive cylinder 531 can drive its output end to move up and down, thereby driving the second connecting plate 540 and the second sealing block 520 to move up and down, so as to move the second sealing block 520 downward and seal the hole on the upper side of the right crankshaft housing 800.

[0051] Furthermore, the second sealing assembly 500 also includes a plurality of second guide posts 550, which are fixedly connected to the lower side of the second connecting plate 540. A plurality of second guide cylinders 420 are provided on the second worktable 400, and the plurality of second guide posts 550 are compatible with the plurality of second guide cylinders 420. Specifically, the lower ends of the plurality of second guide posts 550 are provided with conical guide structures. When the second drive cylinder 531 drives the second connecting plate 540 and the second sealing block 520 to move downwards, the plurality of second guide posts 550 move downwards simultaneously. During the process of entering the second guide cylinders 420, the conical guide structures at the lower ends of the second guide posts 550 guide and adjust the position of the second guide posts 550, thereby achieving horizontal positional adjustment of the second connecting plate 540 and the second sealing block 520 connected to the second guide posts 550.

[0052] According to some embodiments of this application, refer to Figure 1 , Figure 2 , Figure 4The testing mechanism 600 includes two airtightness leak detection modules 620, which are respectively connected to a first vent 210 and a second vent 410 via pipes. Specifically, both airtightness leak detection modules 620 are connected to an external high-pressure air source; one airtightness leak detection module 620 is connected to the first vent 210 via a pipe, and the other airtightness leak detection module 620 is connected to the second vent 410 via a pipe. Specifically, the airtightness leak detection module 620 includes an airtightness leak detector and a solenoid valve. The airtightness leak detector and the solenoid valve are connected. The solenoid valve of the airtightness leak detection module 620 can control the connection or disconnection between the external high-pressure air source and the first vent 210 or the second vent 410. The airtightness leak detector of the airtightness leak detection module 620 can detect the air pressure when the solenoid valve of the airtightness leak detection module 620 is turned on, thereby realizing the detection of the gas pressure of the first vent 210 or the second vent 410, and comparing it with the test data of the standard part to obtain the pressure difference data.

[0053] It is understood that, in some other embodiments, reference is made to... Figure 1 , Figure 2 , Figure 4 The testing mechanism 600 also includes an industrial control touchscreen 610 and multiple indicator lights 630. The multiple indicator lights 630 are electrically connected to the industrial control touchscreen 610, which can control the opening and closing of the multiple indicator lights 630 to more intuitively convey leak detection information to the operator. Specifically, the industrial control touchscreen 610 is also electrically connected to the first solenoid valve 332, the second solenoid valve 532, and the airtightness leak detection module 620. By controlling the operation of the first solenoid valve 332 and the second solenoid valve 532 using the industrial control touchscreen 610, the operation of the first drive cylinder 331 and the second drive cylinder 531 can be controlled, thereby controlling the rise or fall of the first sealing block 320 and the second sealing block 520. The airtightness leak detection module 620 can transmit leak detection data to the industrial control touchscreen 610. The industrial control touchscreen 610 can preset leak judgment parameters and compare the leak detection data with the preset leak judgment parameters to determine whether the leak detection result is qualified.

[0054] It is understood that, in some other embodiments, reference is made to... Figure 1 , Figure 2 , Figure 4The first worktable 200 is equipped with a first positioning cylinder 230 and a second positioning cylinder 240, while the second worktable 400 is equipped with a third positioning cylinder 430 and a fourth positioning cylinder 440. The first positioning cylinder 230 and the second positioning cylinder 240 are positioned opposite each other on both sides of the first sealing ring 310. When the left crankshaft housing 700 is fitted onto the first sealing ring 310, the first positioning cylinder 230 and the second positioning cylinder 240 simultaneously press against the first sealing ring 310 to clamp the left crankshaft housing 700. The third positioning cylinder 430 and the fourth positioning cylinder 440 can clamp the right crankshaft housing 800 using the same principle.

[0055] It is understood that in some other embodiments, the first positioning cylinder 230, the second positioning cylinder 240, the third positioning cylinder 430, and the fourth positioning cylinder 440 are controlled by solenoid valves, and the industrial control touch screen 610 is electrically connected to these solenoid valves to control the operation of the first positioning cylinder 230, the second positioning cylinder 240, the third positioning cylinder 430, and the fourth positioning cylinder 440.

[0056] Working principle: Before performing leak testing on the left crankshaft housing 700 and the right crankshaft housing 800, the air tightness leak testing module 620 is used to test the standard parts of the left crankshaft housing 700 (a device used for comparison with the standard for air leakage degree) and the right crankshaft housing 800 (a device used for comparison with the standard for air leakage degree) to obtain the air leakage test data of the standard parts, which is then used for the subsequent testing of the left crankshaft housing 700 and the right crankshaft housing 800.

[0057] The right crankshaft housing 800 is placed on the first worktable 200 and fitted onto the outside of the second sealing ring 510. The second solenoid valve 532 is opened by the industrial control touch screen 610, and the second drive cylinder 531 drives the second sealing block 520 downward. During the downward movement of the second sealing block 520, the second guide post 550 and the second guide cylinder 420 cooperate to guide and adjust the second sealing block 520 in the horizontal direction. The second sealing block 520 is finally pressed down to the top surface of the right crankshaft housing 800. The third sealing ring 522 and the sealing strip 523 seal the hole on the top surface of the right crankshaft housing 800, and the second sealing ring 510 seals the lower side of the right crankshaft housing 800. The solenoid valve of the airtightness leak detection module 620 controls the connection between the second vent 410 and an external high-pressure air source to inflate the cavity of the right crankshaft housing 800 for 15 seconds and hold the pressure for 5 seconds. Finally, the air pressure is measured. The airtightness leak detection module 620 then measures the air pressure data at the first vent 210 and compares this data with the test data of the corresponding standard part to obtain the pressure difference data, i.e., the leak detection data. Using the same principle, the third vent 521 is connected to an external high-pressure air source to inflate the oil passage cavity of the right crankshaft housing 800 for 5 seconds and hold the pressure for 3 seconds. The airtightness leak detection module 620 then measures the air pressure data at the third vent 521 and compares this data with the test data of the corresponding standard part. The airtightness leak detection module 620 transmits the leak detection data to the industrial control touch screen 610, which compares the leak detection data with preset leak judgment parameters to determine whether the leak detection result is qualified. The second solenoid valve 532 is controlled by the industrial control touch screen 610, which operates the second drive cylinder 531 to move upward, so that the second sealing block 520 is disengaged from the top surface of the right crankshaft housing 800, thus completing one test.

[0058] Using the same principle, the first sealing mechanism and the detection mechanism 600 can perform air leakage detection on the cavity of the left crankshaft housing 700. The solenoid valve of the corresponding air tightness test module 620 controls the connection between the first vent 210 and the external high-pressure air source, inflating the cavity of the left crankshaft housing 700 for 25 seconds and holding the pressure for 12 seconds. Finally, the air tightness test module 620 detects the air pressure data of the second vent 410, and then compares the air pressure data with the test data of the corresponding standard part to obtain the pressure difference data, i.e., the air leakage detection data.

[0059] This application also provides a processing system for a dual-station pressure plugging and leak detection device, which includes a right crankcase pressure fitting processing device, a left crankcase pressure fitting processing device, and a transmission device. The right crankcase pressure fitting processing device is used to press-fit plugs and other components onto the right crankcase 800, the left crankcase pressure fitting processing device is used to press-fit plugs and other components onto the left crankcase 700, and the transmission device is used to transfer the left crankcase 700 and the right crankcase 800 from the left crankcase pressure fitting processing device and the right crankcase pressure fitting processing device to the side of the dual-station pressure plugging and leak detection device, respectively.

[0060] The left crankshaft housing 700 is placed on the first worktable 200, and the right crankshaft housing 800 is placed on the second worktable 400. The first sealing assembly 300 and the second sealing assembly 500 are then used to seal the left crankshaft housing 700 and the right crankshaft housing 800 respectively. Air is then vented through the detection mechanism 600, the first vent 210, and the second vent 410 to detect leaks in both housings. This system can perform leak detection on either the left crankshaft housing 700 or the right crankshaft housing 800 individually or simultaneously, improving leak detection efficiency. Furthermore, the same leak detection device can be used to detect leaks in both crankshaft housings, allowing a single operator to work simultaneously, saving labor costs and reducing floor space requirements. Using high-pressure gas to perform leak detection on the left crankcase 700 and right crankcase 800 is faster than water-based leak testing and avoids wetting the crankcases, improving product cleanliness and eliminating the need for wiping or drying after water-based leak testing, thus further improving work efficiency. It also improves the processing efficiency of processes such as plug installation and leak testing on the left crankcase 700 and right crankcase 800, thereby enhancing the overall processing efficiency of motorcycle crankcases.
