Description

Technical Field

[0001] This invention relates to the field of leak testing machine technology, specifically to a leak testing machine that integrates shell reduction and water testing based on intelligent sensors. Background Technology

[0002] In the integrated water-based leak testing process for reducer housings, the intelligent air pressure sensor is the core detection component. This sensor is equipped with an intelligent data acquisition and transmission module, integrated into the air circuit detection end of the airtight tooling. During leak testing, a set pressure of detection gas is injected into the housing, and the sensor can accurately capture the dynamic changes in air pressure inside the housing. Combined with the water detection method, the air pressure attenuation data is used to determine whether the housing is leaking, and the specific leak location is determined by the location of air bubbles in the water. The accuracy of the air pressure data collected by the sensor is the core foundation for achieving sealing determination and leak location, while the stable state of the water in the tank directly affects the accuracy of air pressure signal feedback and leak location identification.

[0003] During water leak testing of the reducer housing, as the water tank rises, the test base and airtight fixture gradually submerge into the water along with the workpiece. The water, compressed by the workpiece, surges upwards along the gap between the base and the inner wall of the water tank. Once the workpiece is completely submerged, the compressed water flow rapidly converges towards the center, colliding with the inner wall and creating ripples. The direction of the water flow changes from upward surge to diffusion from the center outwards, significantly increasing the impact intensity. Existing leak testing machines lack a drainage structure inside the water tank to adapt to the dynamic changes in water flow. During the surging and ripples of the water... This can easily lead to irregular turbulence within the water tank, resulting in a large number of random, scattered bubbles. These bubbles can cover the detection surface and leakage holes of the reducer housing, interfering with the generation and observation of actual bubbles during leakage and making it difficult to accurately determine the leak location. If a fixed-structure guide component is used, it is impossible to flexibly adjust the flow effect according to changes in water flow impact intensity, and it is impossible to effectively guide water flow in different states. As a result, the problems of water flow disturbance and scattered bubbles within the water tank are difficult to improve, ultimately affecting the leak testing process's judgment of the housing's sealing performance and the location of the leak.

[0004] To address the aforementioned issues, innovative design based on existing methods is urgently needed. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated leak testing machine based on intelligent sensors and a water-cooled casing, in order to solve the problems mentioned in the background. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a leak tester based on intelligent sensors, comprising a leak tester body, a lifting water tank provided on one side of the leak tester body, a test base provided on the leak tester body corresponding to the lifting water tank, an airtight fixture provided on the upper end of the test base, an intelligent air pressure sensor integrated at the air path detection end of the airtight fixture, and a floating drainage component provided inside the lifting water tank;

[0007] The floating drainage component includes two baffle chambers symmetrically arranged in the water tank. A guide rail is installed near the upper end of each baffle chamber. A slider is slidably connected to the outer wall of the guide rail. A float plate is installed at the upper end of the slider. A support bracket is installed on one side of the slider. A round shaft is rotatably connected to the support bracket. First drainage plates are installed on both sides of the round shaft.

[0008] A diversion and flipping assembly is provided between the two flow-blocking chambers to flip the angle of the first diversion plate;

[0009] The support bracket is provided with pore adjustment components on both sides for adjusting the pores of the first guide plate.

[0010] Preferably, the diversion and overturning assembly includes a first rotating shaft rotatably connected to the lower ends of the two flow-blocking chambers, a force-bearing plate is installed in the middle of the first rotating shaft, and an arc-shaped spring is installed between the force-bearing plate and the water tank.

[0011] Preferably, a drive wheel is installed at both ends of the first rotating shaft, and a second rotating shaft is rotatably connected to one side of the slider, with a driven wheel installed on the second rotating shaft corresponding to the drive wheel.

[0012] Preferably, the drive wheel and the driven wheel are both fitted with a belt on their outer walls, and the flow-blocking chamber is rotatably connected to a symmetrically arranged tensioning swing arm corresponding to the belt. A tensioning spring is installed between the tensioning swing arm and the flow-blocking chamber.

[0013] Preferably, a first helical gear is installed on the side of the second rotating shaft near the driven wheel, and a second helical gear is installed in the middle of the circular shaft, with the first helical gear meshing with the second helical gear.

[0014] Preferably, the aperture adjustment assembly includes a second guide plate sleeved on the lower end of the first guide plate, the apertures of the first guide plate and the second guide plate correspond, and a drive bracket is installed on one side of the second guide plate.

[0015] Preferably, each of the drive brackets is equipped with a drive shaft at its upper end, and the two ends of the round shaft are provided with curved grooves corresponding to the drive shafts, and the drive shafts are movably embedded in the curved grooves.

[0016] Preferably, the end of the tensioning swing arm that contacts the belt is roller-shaped, the tensioning spring is arc-shaped, and the center of the arc is consistent with the swing axis of the tensioning swing arm.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention, by setting a floating guide component inside the lifting water tank, utilizes the characteristic of the float plate rising and falling synchronously with the liquid level in the tank to keep the first guide plate in an effective position for water flow guidance. This disperses the upward surging water flow impact during the workpiece immersion stage, reducing water flow disturbance at the source and preventing water flow disturbance from affecting the leakage hole. This ensures the normal generation and clear observation of bubbles when the shell leaks, facilitating accurate location of the leak and providing reliable data for the sealing judgment of the leak testing system. Furthermore, the tensioning structure composed of the tensioning swing arm and tensioning spring ensures stable transmission during the lifting and lowering of the floating guide component, matching the guiding action with the process rhythm of the water tank lifting and lowering, without affecting the normal progress of leak testing.

[0019] 2. This invention, through the cooperation of the guiding and flipping component and the pore adjustment component, triggers the guiding and flipping action by the pressure of the test base when the workpiece is fully submerged and the water flow direction and impact intensity change. This causes the first guiding plate to slowly flip 90°, aligning the plate surface with the direction of the water flow diffusing from the center, thus diverting the strong impact water flow. Simultaneously, the second guiding plate slides, reducing the flow area of ​​the guiding pores, throttling and stabilizing the strong impact water flow, effectively suppressing turbulence, and quickly maintaining a stable state of the water in the tank. This ensures clear capture of air bubbles generated during shell leakage, reduces interference from water sloshing on the internal pressure of the workpiece, guarantees the stability of the data detected by the intelligent air pressure sensor, and enables the location of the leak. Furthermore, the entire guiding and pore adjustment action is naturally triggered by the workpiece immersion process in the water during the leak test, eliminating the need for additional drive and detection structures. While improving the leak test detection accuracy and leak location accuracy, this invention simplifies the equipment structure and enhances the operational stability and process adaptability of the leak tester.

Detailed Implementation

[0029] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0030] Please see Figures 1-8 The present invention provides a technical solution: a leak tester based on intelligent sensors with a reduced shell and integrated water test, including a leak tester body 1, a lifting water tank 2 is provided on one side of the leak tester body 1, a test base 3 is provided on the leak tester body 1 corresponding to the lifting water tank 2, an airtight fixture 4 is provided on the upper end of the test base 3, an intelligent air pressure sensor is integrated at the air path detection end of the airtight fixture 4, and a floating drainage component is provided inside the lifting water tank 2.

[0031] In one embodiment of the present invention, the floating diversion assembly includes two flow-dividing chambers 501 symmetrically arranged inside a water tank. A guide rail 502 is installed near the upper end of each flow-dividing chamber 501. A slider 503 is slidably connected to the outer wall of the guide rail 502. A float plate 504 is installed at the upper end of the slider 503. A support bracket 505 is installed on one side of the slider 503. A circular shaft 506 is rotatably connected to the support bracket 505. First diversion plates 507 are installed on both sides of the circular shaft 506. A diversion tilting assembly is provided between the two flow-dividing chambers 501 for tilting the first diversion plates 507. The diversion tilting assembly includes a first rotating shaft 601 rotatably connected to the lower ends of the two flow-dividing chambers 501. A force-bearing plate 602 is installed in the middle of the first rotating shaft 601. An arc-shaped spring 603 is installed between the force-bearing plate 602 and the water tank. The first rotating shaft 601 has two ends... Each component is equipped with a drive wheel 604. A second rotating shaft 605 is rotatably connected to one side of the slider 503. A driven wheel 606 is installed on the second rotating shaft 605 corresponding to the drive wheel 604. A belt 607 is fitted on the outer wall of both the drive wheel 604 and the driven wheel 606. A tensioning swing arm 608 is symmetrically arranged and rotatably connected to the flow-blocking chamber 501 corresponding to the belt 607. A tensioning spring 609 is installed between the tensioning swing arm 608 and the flow-blocking chamber 501. A first helical gear 610 is installed on the side of the second rotating shaft 605 near the driven wheel 606. A second helical gear 611 is installed in the middle of the round shaft 506. The first helical gear 610 and the second helical gear 611 mesh. The end of the tensioning swing arm 608 that contacts the belt 607 is roller-shaped. The tensioning spring 609 is arc-shaped, and the center of the arc is consistent with the swing axis of the tensioning swing arm 608.

[0032] Before entering the water, the airtight fixture 4 clamps and installs the reducer housing. The air circuit detection end of the airtight fixture 4 is connected to the inner cavity of the housing. The intelligent air pressure sensor integrated in the airtight fixture 4 completes the initial calibration and completes the preliminary airtightness test. The lifting water tank 2 is in the initial low position, and the floating guide component, guide flip component, and orifice adjustment component are all in the initial reset state.

[0033] When the water is submerged, the lifting drive mechanism of the lifting water tank 2 is activated, and the lifting water tank 2 rises upward. The test base 3 and the airtight fixture 4 on the leak test machine body 1 are gradually submerged in the water in the tank as the lifting water tank 2 rises. The intelligent air pressure sensor is submerged in the water synchronously with the airtight fixture 4. The water is squeezed by the test base 3 and the airtight fixture 4 and surges upward along the gap between the test base 3 and the inner wall of the lifting water tank 2. As the test base 3 and the airtight fixture 4 are gradually submerged, the water level in the lifting water tank 2 rises synchronously.

[0034] During the water level rise, the float 504 moves upward under buoyancy, causing the slider 503 to slide upward along the guide rail 502. Simultaneously, the slider 503 drives the support bracket 505, the round shaft 506, and the first guide plate 507 to rise. During this process, the support bracket 505 drives the second rotating shaft 605 to move upward, which in turn drives the driven wheel 606 to pull the belt 607 upward. When the belt 607 is stretched, the tension of the belt 607 overcomes the elasticity of the tension spring 609. Forcefully push the tensioning swing arm 608 to swing around the hinge point, providing sufficient upward space for the belt 607 to be stretched upward. The elastic force of the tensioning spring 609 always acts on the belt 607 through the tensioning swing arm 608, keeping the belt 607 in a taut state. At the same time, the first guide plate 507 moves upward to comb and guide the upward surging water flow around, disperse the surging impact force of the water flow, reduce the disturbance of the water flow in the lifting water tank 2, and avoid the water flow impact to generate a large number of air bubbles that affect the leak test accuracy.

[0035] The tensioning swing arm 608 has a roller-like structure at its end, which converts the sliding friction with the belt 607 into rolling friction, greatly reducing frictional loss during transmission, reducing wear on the belt 607, and extending its service life. At the same time, the arc-shaped tensioning spring 609 keeps the arc center aligned with the swing axis of the tensioning swing arm 608, so that the elastic force of the tensioning spring 609 is always applied radially along the swing arm, ensuring that the tension force on the belt 607 is uniform and stable, and avoiding belt 607 deviation and tooth skipping caused by excessive local force.

[0036] In one embodiment of the present invention, the bearing bracket 505 is provided with a gap adjustment component on both sides for adjusting the gap of the first guide plate 507. The gap adjustment component includes a second guide plate 701 sleeved on the lower end of the first guide plate 507. The gaps of the first guide plate 507 and the second guide plate 701 correspond. A drive bracket 702 is installed on one side of the second guide plate 701. A drive shaft 703 is installed on the upper end of the drive bracket 702. Curved grooves 704 are opened at both ends of the round shaft 506 corresponding to the drive shaft 703. The drive shaft 703 is movably embedded in the curved groove 704.

[0037] Once the water is fully submerged, the lifting water tank 2 rises to the preset height, and the test base 3 sinks to the bottom of the lifting water tank 2. The entire reducer housing workpiece is completely submerged in the water. The intelligent air pressure sensor monitors the pressure change of the detection gas filling the housing in real time. At this time, the water flow in the lifting water tank 2 is squeezed by the complete submersion of the workpiece and quickly converges towards the middle area of ​​the water tank. The converged water flow collides with the inner wall of the lifting water tank 2 to form an echo. The direction of the water flow changes from the original upward surge to a diffusion and surge from the center to the surrounding areas, and the water flow impact intensity is greatly increased.

[0038] As the water flow reverberates and impacts, the test base 3 exerts a downward squeezing force on the force plate 602. The squeezed force plate 602 overcomes the elastic resistance of the arc spring 603, causing the first rotating shaft 601 to rotate around the hinge point of the flow-dividing chamber 501. Simultaneously, the first rotating shaft 601 drives the drive wheels 604 at both ends to rotate. The rotating drive wheels 604, through a tensioned belt 607, drive the driven wheel 606 to rotate. The driven wheel 606 then drives the second rotating shaft 605 to rotate synchronously. The second rotating shaft 605 drives the first helical gear 610 to rotate. Because the first helical gear 610 and the second helical gear 611 mesh, the rotating first helical gear 610 drives the second helical gear 611 to rotate. The second helical gear 611 drives the round shaft 506 to rotate around the hinge point of the support bracket 505. The round shaft 506 further drives the first guide plates 507 on both sides to rotate 90°, so that the surface of the first guide plates 507 is aligned with the water flow spreading from the center outwards. The system adapts to the high-impact diffusion water flow, diverting and guiding it to further disperse the water flow impact. Simultaneously, during the rotation of the circular shaft 506, the curved groove 704 at its end exerts a squeezing and pushing force on the drive shaft 703 embedded in the groove. After being squeezed, the drive shaft 703 drives the drive bracket 702 to move laterally along the first guide plate 507. The drive bracket 702 simultaneously drives the second guide plate 701 to slide laterally along the first guide plate 507, causing the pores of the first guide plate 507 and the second guide plate 701 to be misaligned, reducing the flow area of ​​the guide pores and adjusting the pore size. By reducing the pore size, the high-impact diffusion water flow is throttled and stabilized, reducing the water flow diffusion speed and preventing turbulence and bubbles from being generated due to excessive impact. This ensures the stability of the water flow in the tank during the leak test and ensures that the intelligent air pressure sensor accurately captures the air pressure attenuation data inside the shell. Combined with the location of bubble generation in the water, the system completes the shell sealing determination and leak location location.

[0039] The first guide plate 507 and the second guide plate 701 are nested and sliding together. The flow area is adjusted by misaligning the pores to meet the guidance needs of different water flow impact intensities. At the same time, the sliding engagement between the curved groove 704 and the drive shaft 703 converts the rotational motion of the circular shaft 506 into the linear sliding motion of the second guide plate 701, realizing the control of flipping the guide plate and adjusting the pores. No additional drive structure is required, which simplifies the mechanical structure of the overall device and reduces the failure rate and maintenance cost of the equipment.

[0040] Working principle:

[0041] Before entering the water, the airtight fixture 4 clamps and installs the reducer housing. The air circuit detection end of the airtight fixture 4 is connected to the inner cavity of the housing. The intelligent air pressure sensor integrated in the airtight fixture 4 completes the initial calibration and completes the preliminary airtightness test. The lifting water tank 2 is in the initial low position, and the floating guide component, guide flip component, and orifice adjustment component are all in the initial reset state.

[0042] When the water is submerged, the lifting drive mechanism of the lifting water tank 2 is activated, and the lifting water tank 2 rises upward. The test base 3 and the airtight fixture 4 on the leak test machine body 1 are gradually submerged in the water in the tank as the lifting water tank 2 rises. The intelligent air pressure sensor is submerged in the water synchronously with the airtight fixture 4. The water is squeezed by the test base 3 and the airtight fixture 4 and surges upward along the gap between the test base 3 and the inner wall of the lifting water tank 2. As the test base 3 and the airtight fixture 4 are gradually submerged, the water level in the lifting water tank 2 rises synchronously.

[0043] During the water level rise, the float 504 moves upward under buoyancy, causing the slider 503 to slide upward along the guide rail 502. Simultaneously, the slider 503 drives the support bracket 505, the round shaft 506, and the first guide plate 507 to rise. During this process, the support bracket 505 drives the second rotating shaft 605 to move upward, which in turn drives the driven wheel 606 to pull the belt 607 upward. When the belt 607 is stretched, the tension of the belt 607 overcomes the elasticity of the tension spring 609. Forcefully push the tensioning swing arm 608 to swing around the hinge point, providing sufficient upward space for the belt 607 to be stretched upward. The elastic force of the tensioning spring 609 always acts on the belt 607 through the tensioning swing arm 608, keeping the belt 607 in a taut state. At the same time, the first guide plate 507 moves upward to comb and guide the upward surging water flow around, disperse the surging impact force of the water flow, reduce the disturbance of the water flow in the lifting water tank 2, and avoid the water flow impact to generate a large number of air bubbles that affect the leak test accuracy.

[0044] Once the water is fully submerged, the lifting water tank 2 rises to the preset height, and the test base 3 sinks to the bottom of the lifting water tank 2. The entire reducer housing workpiece is completely submerged in the water. The intelligent air pressure sensor monitors the pressure change of the detection gas filling the housing in real time. At this time, the water flow in the lifting water tank 2 is squeezed by the complete submersion of the workpiece and quickly converges towards the middle area of ​​the water tank. The converged water flow collides with the inner wall of the lifting water tank 2 to form an echo. The direction of the water flow changes from the original upward surge to a diffusion and surge from the center to the surrounding areas, and the water flow impact intensity is greatly increased.

[0045] As the water flow reverberates and impacts, the test base 3 exerts a downward squeezing force on the force plate 602. The squeezed force plate 602 overcomes the elastic resistance of the arc spring 603, causing the first rotating shaft 601 to rotate around the hinge point of the flow-dividing chamber 501. Simultaneously, the first rotating shaft 601 drives the drive wheels 604 at both ends to rotate. The rotating drive wheels 604, through a tensioned belt 607, drive the driven wheel 606 to rotate. The driven wheel 606 then drives the second rotating shaft 605 to rotate synchronously. The second rotating shaft 605 drives the first helical gear 610 to rotate. Because the first helical gear 610 and the second helical gear 611 mesh, the rotating first helical gear 610 drives the second helical gear 611 to rotate. The second helical gear 611 drives the round shaft 506 to rotate around the hinge point of the support bracket 505. The round shaft 506 further drives the first guide plates 507 on both sides to rotate 90°, so that the surface of the first guide plates 507 is aligned with the water flow spreading from the center outwards. The system adapts to the high-impact diffusion water flow, diverting and guiding it to further disperse the water flow impact. Simultaneously, during the rotation of the circular shaft 506, the curved groove 704 at its end exerts a squeezing and pushing force on the drive shaft 703 embedded in the groove. After being squeezed, the drive shaft 703 drives the drive bracket 702 to move laterally along the first guide plate 507. The drive bracket 702 simultaneously drives the second guide plate 701 to slide laterally along the first guide plate 507, causing the pores of the first guide plate 507 and the second guide plate 701 to be misaligned, reducing the flow area of ​​the guide pores and adjusting the pore size. By reducing the pore size, the high-impact diffusion water flow is throttled and stabilized, reducing the water flow diffusion speed and preventing turbulence and bubbles from being generated due to excessive impact. This ensures the stability of the water flow in the tank during the leak test and ensures that the intelligent air pressure sensor accurately captures the air pressure attenuation data inside the shell. Combined with the location of bubble generation in the water, the system completes the shell sealing determination and leak location location.
