Description

Technical Field

[0001] This utility model relates to the field of airtightness testing technology, and in particular to a horizontal rotating water test airtightness testing device. Background Technology

[0002] Welded pipe fittings are sealing connection devices used at the junction of two sections of water pipe. The connection of water pipes needs to ensure its overall airtightness, so the sealing performance of the pipe fittings used for the connection after welding will affect the overall airtightness of the water pipe, and in severe cases, may even cause leakage of the transported fluid. Therefore, it is necessary to conduct airtightness tests on the pipe fittings.

[0003] Water-based air tightness testing involves filling the test piece (product) with compressed air at a specified pressure and determining whether there is a leak by observing the presence or absence of air bubbles in the test water, thus judging the tightness of the test piece.

[0004] Chinese patent document CN216695438U discloses a "rotary water-based airtightness testing device." It includes a frame and a mounting assembly mounted on the frame for placing and installing a wheel rim. Below the mounting assembly, a storage assembly fixed to the frame and used to store the test liquid is located. Below the storage assembly, a lifting unit fixed to the frame and used to control its raising and lowering is located. The mounting assembly consists of a lower base plate, a middle pressure plate, and an upper top plate. A guide unit connects the upper top plate and the lower base plate, allowing the middle pressure plate to move axially back and forth. A testing unit connected to the frame and used to test the airtightness of the wheel rim is mounted on the frame. The above technical solution has limited testing size and limited operational accuracy during the testing process. Summary of the Invention

[0005] This utility model mainly solves the technical problems of limited detection size and limited motion accuracy in the original technical solution. It provides a horizontal rotary water-based air tightness testing device. The device uses a quick clamping mechanism to meet the rapid clamping movement between products of different lengths, and a lifting mechanism to complete the raising and lowering of the water tank, i.e., the product entering and exiting the liquid. At the same time, a rotating air intake mechanism is used to allow the test gas to enter after the product is clamped and to rotate the product during the testing process, which is convenient for the tester to observe. It also includes a clamping pressurization mechanism to meet the different clamping forces required for different products. The device is designed to increase the clamping force adjustment and ensure accurate water immersion testing for products of various specifications.

[0006] The aforementioned technical problems of this utility model are mainly solved by the following technical solution: This utility model includes a frame and a top mounting plate disposed on the top of the frame. It includes a quick-clamping mechanism for quickly clamping different products and a lifting mechanism for raising and lowering the water tank to allow products to enter and exit. It also includes a rotating air intake mechanism for inputting test gas after clamping the product and for rotating the product during the test. The quick-clamping mechanism is mounted on the top mounting plate. The quick-clamping mechanism allows for rapid clamping between products of different lengths. The lifting mechanism raises and lowers the water tank, allowing products to enter and exit the liquid. Simultaneously, the rotating air intake mechanism allows for the input of test gas after clamping and for rotating the product during the test, facilitating observation by the testing personnel. It also includes a clamping pressurization mechanism to adjust and ensure the clamping force for different products, enabling accurate submersion tests for various product specifications.

[0007] Preferably, the quick-clamping mechanism includes a guide rail arranged parallel to each other in the left-right direction, a rack and gear structure facing each other inside the guide rail mounting strip, and a box-type guide rail slider on the guide rail. The guide rail, arranged parallel to each other in the left-right direction, facilitates the left-right movement of the boxes on both sides connected to the box-type guide rail slider, satisfying the quick-clamping movement between products of different lengths. Furthermore, by utilizing the racks facing each other inside the guide rail mounting strip and the gear structure engaging with the racks, only a force is needed to move one side of the rack; the gear structure engaging with the rack will simultaneously rotate, driving the other side of the rack to move in the opposite direction.

[0008] Preferably, the quick clamping mechanism further includes a top cylinder parallel to the guide rail, with a top cylinder connecting plate rigidly connected to the output end of the top cylinder. The top cylinder generates a force parallel to the guide rail on the cylinder connecting plate.

[0009] Preferably, the top cylinder connecting plate is connected to the housing connecting member on one side, and the housing connecting members on both sides are respectively connected to the housing guide rail slider and the housing connecting plate. The housing connecting members on both sides are respectively connected to the housing guide rail sliders on both sides, and the housing connecting members on both sides are respectively fixedly connected to the racks on both sides. The output end of the top cylinder is rigidly connected to the top cylinder connecting plate. When the top cylinder generates a force parallel to the guide rail and outward on the cylinder connecting plate, the cylinder connecting plate drives the housing connecting member on one side, as well as the housing guide rail slider, rack, and housing connecting plate on one side, to move outward. At this time, the gear structure engaged with the rack will rotate simultaneously and drive the rack on the other side to move in the opposite direction. The rack on the other side drives the housing connecting member, housing guide rail slider, and housing connecting plate connected to it to move in the opposite direction synchronously. At this time, the quick clamping mechanism is in the open state.

[0010] When the top cylinder exerts a force parallel to the guide rail towards the center on the cylinder connecting plate, the cylinder connecting plate drives the box connecting piece on one side, as well as the box guide rail slider, rack, and box connecting plate on the other side to move towards the center of the guide rail. At this time, the gear structure engaged with the rack will rotate simultaneously and drive the rack on the other side to move towards the opposite side. The rack on the other side drives the box connecting piece, box guide rail slider, and box connecting plate connected to it to move towards the opposite side synchronously. At this time, the quick clamping mechanism is in the clamping state.

[0011] Preferably, the connecting plates of the housings are connected to the two housings of the rotating air intake mechanism, with a motor and gearbox mounted on one housing. When the connecting plates open or clamp under the action of the top cylinder, the left and right housings achieve rapid clamping of products of different lengths. When the sensor switch detects that the two housings have entered the water tank, and the first electronic pressure gauge 33 detects that the top cylinder pulls back to the set value (initially 0.5MPa-0.8MPa), indicating the product has been clamped, the water tank begins to rise. The left and right housings inflate the product, ensuring the inflation pressure is 0.6MPa. Once inflation is complete, the motor 15 starts, driving the gearbox 17 to rotate the product in the water. Simultaneously, the pressure switch continuously monitors the pressure drop during the test; if it exceeds 0.2MPa, an alarm is triggered. The total reduction ratio of the reducer and gearbox is 317.6, the required rotation speed for the detection area is 2rad / min, and the detection time is 40s. After the test time is reached, the motor stops, the second electronic pressure gauge 34 stops pressure stabilization detection, and the gas inside the product begins to be released. Gas source filters are installed at the gas inlet ends of the left and right chambers to filter the compressed gas entering the product, preventing impurities in the gas from affecting the test results.

[0012] Preferably, the gear structure is provided with rack limiting blocks on both sides to restrict the range of movement of the rack. The rack limiting blocks on both sides of the gear structure restrict the vertical displacement of the gear structure, preventing the gear structure from disengaging during rack movement and affecting the rapid clamping motion between the left and right housings for products of different lengths.

[0013] Preferably, the lifting mechanism includes a vertically upward-mounted water tank cylinder, with the output end of the water tank cylinder rigidly connected to the bottom of the water tank via a water tank cylinder connector. The water tank cylinder connector between the output end of the water tank cylinder and the bottom of the water tank increases the contact area between them, thereby increasing the load-bearing area of ​​the bottom of the water tank. This makes the lifting process more stable and prevents water spillage caused by shaking during the lifting process.

[0014] Preferably, the water tank has a vertical water tank guide rail on its side, and a left and right water tank bracket at its bottom. The water tank guide rail has sliders rigidly connected to the left and right water tank brackets, respectively. The left and right water tank brackets at the bottom also have lifting supports. The limiting action of the left and right water tank brackets and the lifting supports ensures stability during the water tank's lifting process, preventing displacement that could affect product entry. The vertical water tank guide rail on the side, with sliders rigidly connected to the left and right water tank brackets, assists in the movement of the water tank's limiting structure, stabilizing the lifting process driven by the water tank cylinder and preventing displacement that could affect product entry. A water pipe bracket is installed on the side for auxiliary clamping of the water injection pipe.

[0015] Preferably, a clamping and pressurizing mechanism is also included to meet the clamping force requirements of different products. This mechanism includes hydraulic cylinders that move in opposite directions on both sides of the water tank, with a cylinder ejection connecting plate at the cylinder output end. Through holes are provided on both sides of the water tank, allowing the hydraulic cylinder output ends to pass through and apply pressure to the product in the tank. The cylinder ejection connecting plate at the cylinder output end increases the contact area between the cylinder output end and the product, thus achieving sufficient pressure while avoiding localized damage to the product.

[0016] Preferably, the water tank is equipped with a first sensor switch at its working height, a second sensor switch at the bottom of the tank when it descends, a third sensor switch at the maximum opening of the two side panels, and a fourth sensor switch at the point where the two side panels are inside the water tank. In the initial state, when the water tank descends to its bottom, the second sensor switch identifies whether the water tank has reached the designated descent position; when the two side panels are fully open, the third sensor switch identifies whether the two side panels have reached the designated opening position; the hydraulic cylinder retracts to its bottom to prevent collision damage during the water tank's ascent and descent. During testing: when the water tank rises, the hydraulic cylinder retracts, and the two side panels enter the water tank's interior; the fourth sensor switch identifies whether the two side panels have reached the designated opening position. When descending, the hydraulic cylinder retracts, and the two side panels enter the water tank's interior; the fourth sensor switch identifies whether the two side panels have reached the designated opening position. When the hydraulic cylinders clamp and release, when the water tank descends to the bottom, the second sensor switch identifies whether the water tank has reached the designated descent position; when the water tank rises to the working height, the first sensor switch identifies whether the water tank has reached the designated working height, and operation can proceed. When the water tank rises to the working height, the first sensor switch identifies whether the water tank has reached the designated working height, and after reaching the designated position, the two hydraulic cylinders begin to clamp synchronously.

[0017] Induction extension blocks can also be installed on the enclosure connectors to increase the sensing area of ​​the enclosure connectors, making it suitable for testing products of more sizes.

[0018] The beneficial effects of this utility model are: the quick clamping mechanism satisfies the rapid clamping movement between products of different lengths; the lifting mechanism completes the raising and lowering of the water tank, i.e., the product enters and exits the liquid; at the same time, the rotating air intake mechanism enables the entry of test gas after the product is clamped and the rotational movement during the testing process, which is convenient for testers to observe; it also includes a clamping pressurization mechanism to meet the different clamping force of different products, and an added clamping force adjustment and guarantee mechanism to achieve accurate immersion tests for products of various specifications.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this application will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only one preferred embodiment of this application and are only used to explain this application. They do not limit the scope of protection of this application. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0027] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0028] Example: A horizontal rotary water-based air tightness testing device according to this example, such as... Figure 1 , Figure 2 As shown, the system includes a frame 14 and a top mounting plate 9 mounted on top of the frame 14. It also includes a quick-clamping mechanism for quickly clamping different products, a lifting mechanism for raising and lowering the water tank 11 to allow products to enter and exit the tank, and a rotating air intake mechanism for inputting test gas after clamping the product and for rotational movement during testing. The quick-clamping mechanism is mounted on the top mounting plate 9. The quick-clamping mechanism allows for rapid clamping of products of different lengths. The lifting mechanism raises and lowers the water tank, allowing products to enter and exit the liquid. Simultaneously, the rotating air intake mechanism allows for the input of test gas after clamping and for rotational movement during the testing process, facilitating observation by testing personnel. It also includes a clamping pressurization mechanism to adjust and ensure the clamping force varies for different products, enabling accurate submersion testing of various product specifications.

[0029] like Figure 4 , Figure 5As shown, the quick-clamping mechanism includes a guide rail 25 arranged parallel to each other in the left-right direction, a rack 21 and a gear structure 24 arranged facing each other inside the guide rail mounting strip 25, and a box-type guide rail slider 22 on the guide rail 25. The quick-clamping mechanism also includes a top cylinder 1 parallel to the guide rail 25, and a top cylinder connecting plate 8 rigidly connected to the output end of the top cylinder 1. The top cylinder 1 generates a force parallel to the guide rail 25 on the cylinder connecting plate 8. The guide rail 25, which is arranged parallel to each other in the left-right direction, facilitates the left-right movement of the boxes on both sides of the quick-clamping mechanism connected to the box-type guide rail slider 22, satisfying the quick-clamping movement between products of different lengths. Furthermore, by means of the rack 21 arranged facing each other inside the guide rail mounting strip 25 and the gear structure 24 engaging with the rack 21, only one force needs to be provided to move one side of the rack 21, and the gear structure 24 engaging with the rack 21 will rotate simultaneously and drive the other side of the rack 21 to move in the opposite direction. The gear structure 24 is provided with rack limiting blocks 23 on both sides to restrict the range of movement of the rack. The rack limiting blocks 23 on both sides of the gear structure 24 restrict the vertical displacement distance of the gear structure 24, and prevent the gear structure 24 from disengaging during the movement of the rack 21, which would affect the rapid clamping movement between the left and right housings for products of different lengths.

[0030] The top cylinder connecting plate 8 connects to the box body connecting piece 2 on one side. The box body connecting pieces 2 on both sides connect to the box body guide rail slider 22 and the box body connecting plate 7, respectively. The box body connecting pieces 2 on both sides connect to the box body guide rail slider 22 on both sides, and the box body connecting pieces 2 on both sides are fixedly connected to the racks 21 on both sides. The output end of the top cylinder 1 is rigidly connected to the top cylinder connecting plate 8. When the top cylinder 1 generates a force parallel to the guide rail 25 and outward on the cylinder connecting plate 8, the cylinder connecting plate 8 drives the box body connecting piece 2 on one side, as well as the box body guide rail slider 22, rack 21, and box body connecting plate 7 on one side, to move outward. At this time, the gear structure 24 engaged with the rack 21 will rotate simultaneously and drive the rack 21 on the other side to move in the opposite direction. The rack 21 on the other side drives the box body connecting piece 2, box body guide rail slider 22, and box body connecting plate 7 connected to it to move in the opposite direction synchronously. At this time, the quick clamping mechanism is in the open state.

[0031] When the top cylinder 1 exerts a force parallel to the guide rail 25 towards the center on the cylinder connecting plate 8, the cylinder connecting plate 8 drives the box connecting piece 2 on one side, as well as the box guide rail slider 22, rack 21 and box connecting plate 7 on one side to move towards the center of the guide rail. At this time, the gear structure 24 engaged with the rack 21 will rotate simultaneously and drive the rack 21 on the other side to move towards the opposite side. The rack 21 on the other side drives the box connecting piece 2, box guide rail slider 22 and box connecting plate 7 connected to it to move towards the opposite side synchronously. At this time, the quick clamping mechanism is in the clamping state.

[0032] like Figure 6 As shown, the connecting plate 7 connects to the two sides of the rotating air intake mechanism. One side of the housing is equipped with a motor 15 and a gearbox 17. When the connecting plate 7 opens or clamps under the action of the top cylinder 1, the left and right housings 10 quickly clamp products of different lengths. When the sensor detects that both housings have entered the water tank and the first electronic pressure gauge 33 detects that the top cylinder pulls back to the set value (initially 0.5MPa-0.8MPa), indicating the product has been clamped, the water tank begins to rise. The left and right housings inflate the product, ensuring the inflation pressure reaches 0.6MPa. Once inflation is complete, the motor 15 starts, driving the gearbox 17 to rotate the product in the water. Simultaneously, the pressure switch continuously monitors the pressure drop during the test; if it exceeds 0.2MPa, an alarm is triggered. The total reduction ratio of the reducer and gearbox is 317.6. The required speed in the testing area is 2 rad / min, and the testing time is 40 seconds. After the testing time is reached, the motor stops, the second electronic pressure gauge 34 stops stabilizing the pressure, and the gas inside the product begins to be released. The gas inlet terminals of the left chamber 10 and the right chamber are equipped with gas source filters 27 to filter the compressed gas entering the product, preventing impurities in the gas from affecting the test results.

[0033] like Figure 3 As shown, the lifting mechanism includes a vertically upward-mounted water tank cylinder 5. The output end of the water tank cylinder 5 is rigidly connected to the bottom of the water tank 11 via a water tank cylinder connector 6. The water tank cylinder connector 6 is provided between the output end of the water tank cylinder 5 and the bottom of the water tank 11 to increase the contact area between the output end of the water tank cylinder 5 and the bottom of the water tank 11, thereby increasing the force-bearing area at the bottom of the water tank 11, making the lifting process more stable, and preventing water from spilling due to shaking of the water tank 11 during the lifting process.

[0034] The water tank 11 has a vertical water tank guide rail on its side, and a left water tank bracket 13 and a right water tank bracket 20 at its bottom. The water tank guide rail has a slider 4 that is rigidly connected to the left water tank bracket 13 and the right water tank bracket 20 respectively. The left water tank bracket 13 and the right water tank bracket 20 at the bottom of the water tank 11 are also equipped with a water tank lifting bracket 19. The limiting action of the left water tank bracket 13, the right water tank bracket 20, and the water tank lifting bracket 19 ensures the stability of the water tank 11 during lifting and lowering, preventing displacement during lifting and lowering that could affect product entry. The water tank 11 has a vertical water tank guide rail on its side, and a water tank guide rail slider 4 is mounted on the guide rail. The water tank guide rail slider 4 is rigidly connected to the left water tank bracket 13 and the right water tank bracket 20, respectively, to assist in the movement of the water tank limiting structure and to ensure stability during the lifting and lowering process of the water tank 11 driven by the water tank cylinder 5, thus preventing displacement of the water tank 11 during lifting and lowering that could affect the entry of the product. The water pipe bracket 26 is installed on the side for auxiliary clamping of the water injection pipe.

[0035] It also includes a clamping and pressurizing mechanism to meet the clamping force requirements of different products. The clamping and pressurizing mechanism includes hydraulic cylinders 12 that move in opposite directions on both sides of the water tank 11. The output end of the hydraulic cylinder 12 is provided with a hydraulic cylinder ejection connecting plate 18. Through holes are provided on both sides of the water tank 11 to facilitate the output ends of the hydraulic cylinders 12 on both sides of the water tank 11 to apply pressure to the product in the water tank 11 through the through holes. The hydraulic cylinder ejection connecting plate 18 provided on the output end of the hydraulic cylinder 12 can increase the contact area between the output end of the hydraulic cylinder 12 and the product, thereby achieving sufficient pressure while avoiding local damage to the product.

[0036] The water tank has a first sensor switch 28 at its working height, a second sensor switch 29 at the bottom of the tank when it is lowered, a third sensor switch 30 at the maximum opening of the two side panels, and a fourth sensor switch 31 when the two side panels are inside the water tank. In the initial state, when the water tank is lowered to its bottom, the second sensor switch 29 identifies whether the water tank has reached the designated lowering position; when the two side panels are fully open, the third sensor switch 30 identifies whether the two side panels have reached the designated opening position; the hydraulic cylinder retracts to its bottom to prevent collision damage during the water tank's raising and lowering process. During testing: when the water tank rises, the hydraulic cylinder retracts, and the two side panels enter the water tank's interior; the fourth sensor switch 31 identifies whether the two side panels have reached the designated opening position. When the water tank descends, the hydraulic cylinder retracts, and the two side panels enter the water tank's interior; the fourth sensor switch 31 identifies whether the two side panels have reached the designated opening position. When the hydraulic cylinders clamp and release, when the water tank descends to the bottom, the second sensor switch 29 identifies whether the water tank has reached the designated descent position. When the water tank rises to the working height, the first sensor switch 28 identifies whether the water tank has reached the designated working height, at which point operation can proceed. When the water tank rises to the working height, the first sensor switch 28 identifies whether the water tank has reached the designated working height, and after reaching the designated position, the two hydraulic cylinders begin to clamp synchronously. A sensor extension block can also be installed on the housing connector 2 to increase the sensing area of ​​the housing connector 2, enabling testing of products of more sizes.

[0037] At work,

[0038] 1. Initial equipment status:

[0039] a. When the water tank descends to the bottom, the second sensor switch 29 is activated.

[0040] b. When both boxes are opened to their maximum size, the third sensor switch 30 is activated.

[0041] c. The hydraulic cylinder retracts to its lowest point.

[0042] 2. Equipment reset action:

[0043] a. The top cylinder is pushed out to its maximum position, and the third sensor switch 30 is activated.

[0046] 3. Manual operation of the equipment:

[0047] a. The two tanks are clamped and released, with the water tank at the bottom and the oil cylinder retracted.

[0048] b. Water tank rising and falling. When rising, the hydraulic cylinder retracts, and both tanks enter the water tank's interior area, triggering the fourth sensor switch 31. When falling, the hydraulic cylinder retracts, and both tanks remain within the water tank's interior area.

[0049] c. When the hydraulic cylinder clamps and releases, the water tank is at the top, the first sensor switch 28 is at the bottom, and the second sensor switch 29 is at the top, it can be operated.

[0050] d. Rotation can be performed in manual mode.

[0051] 4. One automatic operation process of the equipment:

[0052] a. Start the test to check if the device status is in the initial position.

[0053] b. To check if the water tank is at the bottom, the second sensor switch 29 and the fourth sensor switch 31 simultaneously detect the safe position of the tank. That is, if the fourth sensor switch 31 detects that the two tanks are outside the water tank area, the water tank is prohibited from rising.

[0054] c. When the water tank is detected at the bottom, the second sensor switch 29 pulls the cylinder back, and the two tanks begin to clamp together.

[0055] d. When the fourth sensor switch 31 detects that the two boxes have entered the water tank's interior range, and the first electronic pressure gauge 33 detects that the top cylinder pulls back the pressure to the set value, initially set at 0.5MPa-0.8MPa, meaning the product has been clamped, the water tank begins to rise.

[0056] e. To check if the water tank has risen to the correct position, the first sensor switch 28 is activated. Once the position is reached, the two hydraulic cylinders begin to clamp synchronously.

[0057] f. Check if the clamping pressure of the two hydraulic cylinders has reached the set value. Once it has, start inflating the product.

[0058] g. Check the product inflation pressure. Verify that the second electronic pressure gauge 34 is in the correct position (0.6 MPa). Once inflation is complete, the motor will start. Simultaneously, the pressure switch continuously monitors the pressure drop during the test. If the pressure drop exceeds 0.2 MPa, an alarm will sound.

[0059] h. The motor rotates, the total reduction ratio of the reducer and gearbox is 317.6, the required speed of the detection area is 2 rad / min, and the detection time is 40s.

[0060] i. After the test time is reached, the motor stops, the second electronic pressure gauge 34 stops the pressure stabilization test, and begins to release air from the inside of the product.

[0061] j. Detect the internal air pressure of the product. When the second electronic pressure gauge 34 drops to 0MPa, the oil cylinder begins to retract.

[0062] k. The water tank begins to descend after the hydraulic cylinder retracts into its position; the water tank must not descend if the hydraulic cylinder has not retracted.

[0063] 1. After the water tank is detected to have descended to the correct position, the top cylinder of the second sensor switch 29 begins to extend.

[0064] m. When the two boxes are opened to their initial positions, the third sensor switch 30 completes one detection action.

[0065] The quick-clamping mechanism enables rapid clamping between products of different lengths. The lifting mechanism raises and lowers the water tank, allowing the product to enter and exit the liquid. Simultaneously, the rotating air intake mechanism allows the test gas to enter after the product is clamped and facilitates rotational movement during the testing process, making it easy for testers to observe. It also includes a clamping pressurization mechanism to meet the varying clamping forces required for different products, and an added clamping force adjustment mechanism to ensure accurate immersion testing for products of various specifications.
