Description

Technical Field

[0001] The present application relates to the technical field of welding sealing testing, and in particular to an ultrasonic welding sealing testing tool. Background Art

[0002] The main function of the welding sealing test tool is to verify whether the sealing performance of the welding joint meets the design requirements. By applying a certain pressure and monitoring relevant parameters, the sealing performance of the welding joint can be evaluated and it can be ensured that there will be no leakage or other problems in actual use. This is especially important for some critical welding joints, such as pipes, containers or sealing structures. During the test, the products to be tested usually include sealing heads and vents. Ventilation is conducted through the vent to determine whether there is gas flow at the sealing head and the sealing performance of the vent.

[0003] Regarding the above-mentioned related technologies, the sealing head is formed by ultrasonic welding, which has extremely high sealing performance. If there is a leakage, the human body cannot sense the gas flow, which can easily affect the product qualification rate and thus affect the production efficiency. Utility Model Content

[0004] In order to improve the phenomenon of low production efficiency caused by the inability of the human body to accurately judge the sealing of products with high sealing properties, the present application provides an ultrasonic welding sealing test tool.

[0005] The present application provides an ultrasonic welding sealing test tool, which adopts the following technical solution:

[0006] An ultrasonic welding sealing test tool comprises a water tank, wherein a test plate for detecting the sealing of a product is provided in the water tank, an air supply cylinder is provided on the test plate, a copper plug is connected to the end of the piston rod of the air supply cylinder away from the air supply cylinder, a fixture for fixing the product is provided at the end of the copper plug away from the air supply cylinder, an air supply device for air supply is provided at the top of the water tank, the air supply device is respectively connected to the copper plug and the air supply cylinder through an air pipe, and a push rod for controlling the switch of the air supply device is provided on the air supply device.

[0007] By adopting the above technical solution, when it is necessary to test the sealing of the product, the staff first fills the water tank with water, then fixes the product on the fixture, and then pushes the push rod to start the air supply cylinder. The piston rod of the air supply cylinder drives the copper plug to move, thereby blocking the product's ventilation pipe. Since there is continuous gas output in the copper plug, if bubbles are generated at the sealing head, it means that the product is leaking. Otherwise, the product is qualified. The test results are easy to observe, which is conducive to improving the accuracy of the sealing test.

[0008] Optionally, the number of air pipes connecting the air supply device and the air supply cylinder is two.

[0009] By adopting the above technical solution, two air pipes are used for gas intake and exhaust respectively. One air pipe transports gas from the air supplier to the air supply cylinder, and the air supply cylinder works; the other air pipe discharges the exhaust gas in the air supply cylinder to maintain the pressure balance in the air supply cylinder, which is conducive to the normal operation and circulation of the cylinder.

[0010] Optionally, a control valve is provided between the air supply cylinder and the copper plug and the air supply device, and the control valve is arranged at one end of the air pipe close to the air supply device.

[0011] By adopting the above technical solution, when the air supply cylinder pushes the copper plug to the specified position, the staff starts the control valve to close the air pipe between the air supply cylinder and the air supplier, avoiding damage to the product caused by continuous operation of the cylinder. Reasonable control of gas flow is conducive to improving the accuracy of the test results.

[0012] Optionally, the fixture includes a handle and a clamping portion for clamping and fixing the product, a support seat is provided on the test board, the handle is arranged on the support seat, and the handle is hinged to the clamping portion.

[0013] By adopting the above technical solution, when the product needs to be fixed, the staff operates the clamping part through the handle to fix the product on the support seat, so that the ventilation pipe of the product is facing the copper plug, ensuring the normal operation of the equipment and helping to improve the stability of the tooling.

[0014] Optionally, a handle cover is provided on the outer side of the handle.

[0015] By adopting the above technical solution and providing a handle cover, it is convenient for workers to operate the handle, providing the workers with a better operating experience, and helping to improve the comfort of the workers.

[0016] Optionally, the water level in the water tank should be higher than the plane where the handle is located.

[0017] By adopting the above technical solution, if the water level in the water tank is lower than the plane where the handle is located, the test result fed back by the test tooling, that is, whether bubbles are generated or not, cannot be clearly known, which seriously affects the test result of the product sealing test. On the contrary, if the water level is higher than the plane where the handle is located, the test result is relatively clear, which is conducive to improving the accuracy of the test result.

[0018] Optionally, an L-shaped connecting pipe is provided on one side of the air pipe close to the air supplier, one end of the L-shaped connecting pipe is connected to the air supplier, and the other end is connected to the air pipe.

[0019] By adopting the above technical solution, the direction of gas flow can be changed by setting an L-shaped connecting pipe. When the pipeline needs to change the flow direction, the L-shaped connecting pipe can guide the gas to the required direction to meet the process requirements.

[0020] Optionally, a protrusion is provided at one end of the copper plug away from the air supply cylinder, and the protrusion is aligned with the part of the product to be sealed and matches the shape and size.

[0021] By adopting the above technical solution, when the ventilation pipe of the product needs to be sealed, the staff starts the air supply cylinder, and the piston rod of the air supply cylinder drives the copper plug to move, thereby driving the protrusion to move to the ventilation pipe of the product, which is beneficial to improve the sealing of the structure and thus improve the accuracy of the test results.

[0022] In summary, the present application includes at least one of the following beneficial technical effects of ultrasonic welding sealing test tooling:

[0023] 1. By setting up a water tank, a test plate, an air supply cylinder, a copper plug, a fixture, an air supply device and a push rod, when the product's sealing performance needs to be tested, the staff first fills the water tank with water, then fixes the product on the fixture, and then pushes the push rod to start the air supply cylinder. The piston rod of the air supply cylinder drives the copper plug to move, thereby blocking the product's ventilation pipe. Since there is continuous gas output in the copper plug, if bubbles are generated at the sealing head, it means that the product is leaking. Otherwise, the product is qualified. The test results are easy to observe, which is conducive to improving the accuracy of the sealing test;

[0024] 2. By setting up the gas supply cylinder, copper plug, gas supply device and control valve, when the gas supply cylinder pushes the copper plug to the specified position, the staff starts the control valve to close the air pipe between the gas supply cylinder and the gas supply device to avoid damage to the product caused by continuous operation of the cylinder. Reasonable control of gas flow is conducive to improving the accuracy of test results. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0030] The embodiment of the present application discloses an ultrasonic welding sealing test tool.

[0031] Reference Figure 1 An ultrasonic welding sealing test tool comprises a water tank 1, an air supply part 2 and a test part 3. The water tank 1 is arranged vertically, the air supply part 2 is arranged at the top of the water tank 1, and the test part 3 is arranged at the bottom of the water tank 1. The water tank 1 contains water for observing the test results, the air supply part 2 provides gas for the test part 3, and the test part 3 tests the sealing of the product.

[0032] Reference Figure 1 and Figure 2 The water level in the water tank 1 is higher than the plane where the test piece 3 is located. If the water level in the water tank 1 is lower than the plane where the handle 341 is located, the test result fed back by the test tooling, that is, whether bubbles are generated or not, cannot be clearly known, which seriously affects the test result of the product sealing test. On the contrary, if the water level is higher than the plane where the handle 341 is located, the test result is relatively clear, which is conducive to improving the accuracy of the test result.

[0033] Reference Figure 1 and Figure 3 The air supply component 2 includes an air supply device 21, three air pipes 22 and a push rod 23. The air supply device 21 is arranged on the upper end surface of the water tank 1, and the push rod 23 is arranged on the upper end surface of the air supply device 21. The air supply device 21 is connected to the test piece 3 through the three air pipes 22. The air pipes 22 are each provided with an L-shaped connecting pipe 25 on one side close to the air supply device 21. One end of the L-shaped connecting pipe 25 is connected to the air supply device 21, and the other end is connected to the air pipe 22.

[0034] Reference Figure 1 and Figure 3 The gas supply device 21 is started by setting a push rod 23, so that the gas flows in the three gas pipes 22. The direction of the gas flow can be changed by setting an L-shaped connecting pipe 25. When the pipeline needs to change the flow direction, the L-shaped connecting pipe 25 can guide the gas to the required direction to meet the process requirements.

[0035] Reference Figure 2 and Figure 3 The test piece 3 includes a test plate 31, an air supply cylinder 32, a copper plug 33 and a fixer 34. The test plate 31 is arranged inside the water tank 1, and the air supply cylinder 32 is arranged on the upper end surface of the test plate. The piston rod of the air supply cylinder 32 is coaxially fixedly connected with the copper plug 33. A protrusion 331 is provided at the end of the copper plug 33 away from the air supply cylinder 32. The protrusion 331 is aligned with the sealing position of the product and the shape and size match. There are two air pipes 22 connecting the air supply device 21 and the air supply cylinder 32, and there is one air pipe 22 connecting the air supply device 21 and the copper plug 33. Control valves 24 are provided between the air supply cylinder 32 and the copper plug 33 and the air supply device 21. The control valves 24 are all arranged at one end of the air pipe 22 close to the air supply device 21.

[0036] Reference Figure 2 and Figure 3 The two air pipes 22 are used for gas intake and exhaust respectively. One air pipe 22 transports gas from the air supply device 21 to the air supply cylinder 32, and the air supply cylinder 32 works. The other air pipe 22 discharges the exhaust gas in the air supply cylinder 32 to maintain the pressure balance in the air supply cylinder 32, which is conducive to the normal operation and circulation of the cylinder. When the ventilation pipe 22 of the product needs to be sealed, the staff starts the air supply cylinder 32, and the piston rod of the air supply cylinder 32 drives the copper plug 33 to move, thereby driving the protrusion 331 to move to the ventilation pipe 22 of the product. When the air supply cylinder 32 pushes the copper plug 33 to the specified position, the staff starts the control valve 24 to close the air pipe 22 between the air supply cylinder 32 and the air supply device 21 to avoid damage to the product due to continuous operation of the cylinder. Reasonable control of gas flow is conducive to improving the accuracy of the test results.

[0037] Reference Figure 2 and Figure 3 The fixture 34 includes a handle 341, a support seat 342 and a clamping portion 343. The support seat 342 is arranged on the test board 31, and the handle 341 is arranged on the support seat 342. The handle 341 is hinged to the clamp, and a handle 341 sleeve is arranged on the outer side of the handle 341. The handle 341 sleeve is arranged to facilitate the staff to operate the handle 341 and provide the staff with a better operating experience. When the product needs to be fixed, the staff controls the clamp through the handle 341 to fix the product on the support seat 342, so that the ventilation pipe 22 of the product is facing the copper plug 33, ensuring the normal operation of the equipment and helping to improve the stability of the tooling.

[0038] The implementation principle of an ultrasonic welding sealing test tool in an embodiment of the present application is as follows: when the sealing of a product needs to be tested, the staff first fills the water tank 1 with water, then fixes the product on the fixture 34, and then pushes the push rod 23 to start the air supply cylinder 32. The piston rod of the air supply cylinder 32 drives the copper plug 33 to move, thereby blocking the ventilation pipe 22 of the product. Since there is continuous gas output in the copper plug 33, if bubbles are generated at the sealing head, it indicates that the product is leaking. Otherwise, the product is qualified. The test results are easy to observe, which is conducive to improving the accuracy of the sealing test.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
