[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] Example 1: Please refer to Figure 1-3 , Figure 5As shown, this utility model is a vertical water testing machine, including an upper frame profile 10. The upper frame profile 10 is made of 60×60 square tubing welded together, and the internal structural components are fixed with welded square tubing. A platform 24 is fixedly installed at the bottom of the upper frame profile 10, and a through hole is opened in the middle of the platform 24. A lifting cylinder 7 is installed at the top of the upper frame profile 10. Four slide rails are added around the lifting cylinder 7 to assist sliding. The design of a cylinder plus linear guide rail floating mechanism ensures that the product 21 will not get stuck after being lifted and lowered to the water tank 28. Considering safety during high-pressure airtightness testing, the equipment is equipped with an induction check valve. During testing, the lifting cylinder 7 is locked to prevent accidental injury to the operator if the lifting cylinder 7 descends suddenly due to power failure. The lower end of the lifting cylinder 7... A lifting assembly 25 is fixedly connected and is movably engaged in a through hole in the middle of the platform panel 24. The lifting assembly 25 is used to drive multiple products 21 to reciprocate vertically to achieve water testing. Multiple through holes 27 are provided on the lower end face of the lifting assembly 25. The through holes 27 facilitate the rapid immersion of water in the products 21 during the downward movement to complete the test. The lifting assembly 25 is a rectangular frame to ensure the consistency of the displacement of the products 21 under the drive of the lifting cylinder 7. A water tank 28 is provided below the lifting assembly 25. The size of the lifting assembly 25 is smaller than the size of the water tank 28 below. The lifting assembly 25 moves downward and is movably fitted into the water tank 28 below. The water in the water tank 28 quickly immerses the products 21 to be tested through the through holes 27.
[0026] A detection base plate 26 is fixedly connected to the upper end of the lower end face of the lifting assembly 25. The lower end of the detection base plate 26 has multiple holes corresponding to the through holes 27 at the lower end of the lifting assembly 25. Multiple push cylinders 18 are arranged in an array on one end of the upper surface of the detection base plate 26. The push cylinders 18 are arranged at equal intervals on the detection base plate 26. A product clamping mechanism 14 is installed at the end of the multiple push cylinders 18. The product clamping mechanism 14 is used for horizontal reciprocating movement to quickly change the clamping of different models of detection products 21 for air tightness testing. A push clamp 17 is provided between the push cylinders 18 and the product clamping mechanism 14. The push clamp 17 is used to press and block the product 21 to prevent the product 21 from rebounding after being pushed forward. An aluminum alloy linear guide rail 20 is provided on one side of the product clamping mechanism 14 at the upper end of the detection base plate 26. The aluminum alloy linear guide rail 20 is slidably connected to the product clamping mechanism 14. Handles 23 are symmetrically fixed at both ends of the detection base plate 26.
[0027] In summary, this vertical water testing machine allows the operator to move the push cylinder 18 backward to place the product 21 into the product clamping mechanism 14 for clamping and fixing. The lifting cylinder 7 is then activated to move the lifting assembly 25 downward, lowering the product 21 into the water tank 28 for airtightness testing. Based on the feedback data from the pressure sensor, the machine employs both direct pressure testing and manual observation of the product 21's expansion and deformation, as well as micro-pore leakage detection in the water, thus achieving multiple testing methods and improving testing accuracy.
[0028] Example 2: Based on Example 1, please refer to... Figure 4 As shown, the product clamping mechanism 14 includes a rear product fixing seat 19 mounted on multiple aluminum alloy linear guide rails 20. One end of the detection base plate 26 is arrayed with multiple front product fixing seats 22 that match the rear product fixing seats 19. The replacement of the clamps of the front product fixing seats 22 and the rear product fixing seats 19 only requires disassembling and assembling the screws of the corresponding clamps and positioning pins to achieve quick mold change, realize the switching of products 21 of similar shape but different specifications, and improve the versatility of the equipment. Both the front product fixing seats 22 and the rear product fixing seats 19 are made of metal-coated nylon material to protect the electrophoretic paint from scratching the product 21. The product 21 is clamped between the rear product fixing seats 19 and the front product fixing seats 22. The push cylinder 18 drives the aluminum alloy linear guide rails 20 to move horizontally back and forth, thereby driving the rear product fixing seats 19 to move back and forth. The rear push cylinder 18 of the clamp adopts an adjustable design to adapt to products 21 of different specifications.
[0029] In summary, this utility model equipment is a general-purpose model. The push cylinder 18 drives the aluminum alloy linear guide rail 20 to move horizontally and reciprocally, which can adapt to the detection of products 21 of different specifications. It is equipped with detachable and replaceable fixtures for quick mold changing, so as to realize the switching of products 21 of similar shape but different specifications, thereby improving the versatility of the equipment.
[0030] Example 3: Based on Examples 1 and 2, please refer to... Figure 1-2 As shown, a tank chain 12 is provided on one side of the lifting cylinder 7 at the upper end of the upper frame profile 10. The tank chain 12 is a mechanical device for protecting flexible pipelines such as cables, air pipes, and hydraulic pipes, and is used to prevent the pipelines from being damaged by friction, stretching or twisting during movement.
[0031] Multiple pressure gauges 8 are fixedly arranged in an array on one side of the upper frame profile 10. One end of each pressure gauge 8 is connected to a pressure sensor, which is connected to the air pipe on the product 21. The pressure sensor determines the airtightness of the product 21 by monitoring the pressure changes during the pressure holding period. Each pressure gauge 8 corresponds one-to-one with a product 21 clamped on the product clamping mechanism 14, facilitating quick identification of the test results of the product 21. An alarm light 9 is provided below each of the multiple pressure gauges 8. The alarm light 9 is used to alert the operator when the equipment malfunctions or the pressure sensor detects an abnormality.
[0032] A tri-color light 1 is provided on one side of the upper end of the upper frame profile 10. The tri-color light 1 is used to display the operating status of the equipment (such as running, standby, fault, etc.). An industrial computer 2 is provided on one side of the upper frame profile 10. The industrial computer 2 is used to store test results. It has a large storage capacity and fast program retrieval. A touch screen 3 is provided below the industrial computer 2. The touch screen 3 is used to input the test results as qualified or unqualified (NG) to facilitate subsequent airtightness analysis of product 21. A control button 13 is provided below the touch screen 3.
[0033] Safety light curtains 15 are symmetrically arranged on both sides of the through hole on one side of the upper frame profile 10. The safety light curtains 15 are used to monitor and detect dangerous areas to prevent personnel from contacting dangerous parts, thereby ensuring the safety of operators.
[0034] The lower end of the upper frame profile 10 is fixedly connected to the lower frame sheet metal 11. A triplet 16 is provided on one side of the lower frame sheet metal 11. The triplet 16 is used to process compressed air to ensure stable operation and detection accuracy of the equipment. A button box 4 and an NG box 5 are provided on the upper end of the other side of the lower frame sheet metal 11. Multiple feet 6 are symmetrically provided at the bottom end of the lower frame sheet metal 11.
[0035] Both ends of the rear product mounting base 19 and the front product mounting base 22 are designed with enlarged chamfers to ensure that the eccentric product 21 can be properly placed into the fixture.
[0036] In summary, during operation, operators can monitor the pressure changes of each product 21 during the pressure holding period using pressure gauge 8 and alarm light 9. Products 21 with poor airtightness will trigger alarm light 9 to alert the operator. The industrial computer 2 and touch screen 3 can quickly retrieve programs, which have storage functions, display inflation time, test time, input air pressure and pressure drop values, and input test results, facilitating subsequent system analysis. Safety light curtain 15 is used to detect dangerous operating areas to ensure operator safety.
[0037] The working principle of this utility model is as follows: A vertical water testing machine is used. The operator places six products 21 in the product clamping mechanism 14, inserts an air pipe, presses the button box 4, and pushes the cylinder 18 forward to push the products 21. The lifting cylinder 7 drives multiple products 21 down into the water tank 28 for air tightness testing. The equipment's air pressure sensor monitors the process and completes the direct pressure test. The operator observes whether bubbles are generated in the water. If so, the information is manually entered into the touch screen 3. After the test is completed, the lifting cylinder 7 rises, and the operator uses an air gun to blow away the water droplets on the products 21. The products are then collected and stored for later use.
