Description

Technical Field

[0001] This utility model relates to the field of airtightness testing technology, specifically to an airtightness testing device for industrial parts. Background Technology

[0002] As people's living standards improve, their consumption increases, leading to a rise in demand for various products and equipment, and consequently, a growing market for industrial components. In recent years, industrial component manufacturers have also developed rapidly. Industrial components are generally composed of two or more parts working together. For some industrial components requiring airtightness, gaps may exist between the parts after assembly due to insufficient fit, necessitating airtightness testing.

[0003] In existing technologies, the airtightness testing of industrial components typically involves sealing one end of the component with an air pump, adjusting the input air pressure and duration, and then submerging the other end of the component in water. The presence of air bubbles in the water is then used to determine whether the airtightness meets the standards. This method is inefficient, cannot test multiple components simultaneously, and submerging the components directly in water can cause secondary contamination, requiring drying. To address these issues, an airtightness testing device for industrial components is proposed. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing an industrial component airtightness testing device that can test multiple industrial components at once, improving testing efficiency and preventing secondary pollution to the industrial components.

During testing, one end of the testing accessory is sealed to the first positioning slot, and the other end is sealed to the second positioning slot. The first air inlet and the first air outlet are sealed together. If the test fails, the gas can pass through the testing accessory, enter the transparent detection tube through the second pipe, and form bubbles. By placing industrial parts in the testing fixture for testing, there is no need to immerse the industrial parts in water for testing. Multiple industrial parts can be tested simultaneously, solving the problems of low testing efficiency and secondary pollution of industrial parts.

[0030] like Figure 1-5As shown, this utility model discloses an industrial component airtightness testing device, including a frame 10. The frame 10 is equipped with a testing fixture 20, an air pump 30, several transparent testing tubes 43 containing testing liquid, and a control mechanism for controlling the cooperation of the testing fixture 20 and the air pump 30. The testing fixture 20 includes a first module 21, a second module 23, and a driving component 24 for driving the first module 21 and / or the second module 23 to move closer or further apart. The first module 21 is provided with several first positioning grooves 211 for placing the component to be tested. The first module 21 is provided with an air chamber 212. The first positioning grooves 211 are all connected to the air chamber 212. The first module 21 is also provided with a first air inlet 22 connected to the air chamber 212. The second module 23 is provided with several second positioning grooves 231 corresponding one-to-one with the first positioning grooves 211. The second module 23 is also provided with a second air inlet 232 connected to the second air inlet 232. The device includes a first air outlet 233 and several second air outlets 234 that correspond one-to-one with the second positioning grooves 231. The second air inlet 232 is connected to the air pump 30 through a first pipe (not shown in the figure), and the second air outlets 234 are connected to the transparent detection tubes 43 through second pipes (not shown in the figure). During testing, one end of the testing accessory is sealed to the first positioning groove 211, and the other end is sealed to the second positioning groove 231. The first air inlet 22 is sealed to the first air outlet 233. If the test fails, the gas can pass through the testing accessory, enter the transparent detection tube 43 through the second pipe, and form bubbles. The diameter of the second pipe is smaller than the diameter of the transparent detection tube 43. By placing the industrial accessory 12 in the testing fixture 20 for testing, it is not necessary to put the industrial accessory 12 into water for testing. Multiple industrial accessories 12 can be tested simultaneously, solving the problems of low testing efficiency and secondary pollution to the industrial accessories 12.

[0031] In this utility model, the air pump 30 is a mature product that can be purchased directly on the market. Its structure and technical principles are existing technologies and will not be described in detail here.

[0032] The frame 10 is also provided with a drive mounting bracket 13. The drive component 24 is mounted on the drive mounting bracket 13. The drive end of the drive component 24 is fixedly connected to the second module 23. A slide rod 235 is fixedly connected to the second module 23. The drive mounting bracket 13 is provided with a corresponding sliding sleeve 131 for the slide rod 235. The slide rod 235 is slidably connected to the drive mounting bracket 13 through the sliding sleeve 131. The cooperation between the slide rod 235 and the sliding sleeve 131 makes the movement of the second module 23 more stable.

[0033] In this invention, there are two slide rods 235 arranged in parallel. The number of sliding sleeves 131 corresponds to the number of slide rods 235. By arranging the two slide rods 235 in parallel, the movement stability of the second module 23 can be further improved.

[0034] In this utility model, the driving component 24 is a cylinder, the number of the second module 23 is two, and the number of the driving component 24 is two. By setting two second modules 23, during testing, the driving component 24 can apply force to the second module 23 more evenly, thereby improving the sealing performance when the industrial part 12 is sealed to the first positioning groove 211 and the second positioning groove 231.

[0035] The frame 10 is also provided with a third positioning slot 141, and the first module 21 is detachably installed in the third positioning slot 141. The frame 10 is detachably provided with a mounting plate 14, and the third positioning slot 141 is set on the mounting plate 14. The drive mounting bracket 13 is detachably installed on the mounting plate 14. By setting the third positioning slot 141, at least two first modules 21 can be prepared in actual use, so as to realize the quick replacement of the first module 21. During the test, after the industrial parts 12 on the previous first module 21 are tested, the entire first module 21 can be directly removed, and another first module 21 filled with industrial parts 12 to be tested can be directly placed in the third positioning slot 141 for testing, thereby improving the testing efficiency.

[0036] The frame 10 is also provided with a placement platform 15 for placing the first module 21. By setting the placement platform 15, at least two first modules 21 can be set in actual use. When the first module 21 is being tested in the third positioning slot 141, another first module 21 filled with industrial parts 12 can be placed on the placement platform 15 for easy retrieval.

[0037] The frame 10 is also equipped with a water tank 40, which has several water outlets (not shown in the figure) corresponding one-to-one with the transparent detection tubes 43. The transparent detection tubes 43 are connected to the water tank 40 through the water outlets. The frame 10 is also equipped with a water tank mounting bracket 41, on which both the water tank 40 and the transparent detection tubes 43 are mounted. The transparent detection tubes 43 are located below the water tank 40. A transparent detection tube mounting bracket 42 is mounted on the water tank mounting bracket 41, and several transparent detection tubes 43 are mounted at intervals on the transparent detection tube mounting bracket 42. By setting up the water tank 40, the detection liquid in the transparent detection tubes 43 can be prevented from flowing out of the transparent detection tubes 43 due to the impact of gas.

[0038] In this invention, the transparent detection tube 43 is connected to the water outlet through a third pipe (not shown in the figure).

[0039] In this invention, the water outlet is located at the bottom of the water tank 40.

[0040] In this invention, the highest point of the second pipe is higher than the highest water level in the water tank 40, so that the detection liquid in the transparent detection tube 43 will not flow into the second module 23 through the second pipe.

[0041] The frame 10 is also equipped with several detectors that correspond one-to-one with the transparent detection tube 43. The detectors are used to detect whether air bubbles are generated inside the transparent detection tube 43. By setting the detectors, the detection results can be detected, which facilitates the judgment of the detection results and improves the detection efficiency.

[0042] In this invention, the detector includes a sensor 44 and an alarm light 17, both of which are communicatively connected to the control mechanism.

[0043] It should be understood that the sensor 44 and the alarm light 17 are both mature products that can be purchased directly on the market, and their structure and technical principles are existing technologies, which will not be described in detail here.

[0044] In this invention, the control mechanism includes a control box 18 and two control switches 19. During testing, both control switches 19 must be pressed simultaneously to start the device for testing.

[0045] In this invention, the control mechanism is a mature product that can be purchased directly from the market, and its structure and technical principles are existing technologies, which will not be described in detail here.

[0046] The frame 10 is also provided with a safety light curtain 16 arranged opposite to it, and the safety light curtain 16 is located in front of the detection fixture 20; by setting the safety light curtain 16, the detection safety can be improved and the operator can be prevented from being injured.

[0047] The method of using this utility model is as follows: After filling the first module 21 with the industrial parts 12 to be tested, place it into the third positioning groove 141. Press the control switch 19, and the drive component 24 drives the second module 23 to move towards the first module 21 to clamp the industrial parts 12. The first air inlet 22 and the first air outlet 233 are sealed together. Then, the control mechanism controls the air pump 30 to output gas into the second module 23 through the first pipe and the second air inlet 232, and then into the air chamber 212 through the first air outlet 233 and the first air inlet 22 in sequence. When the industrial parts 12 are unqualified, the gas will enter the second module 23 through the gaps between the industrial parts 12, and then enter the transparent detection tube 43 through the second air outlet 234 and the second pipe, thus producing bubbles. At the same time, the sensor... The sensor 44 will detect bubbles. The control mechanism receives the signal generated by the sensor 44 and controls the alarm light 17 to sound an alarm. The control mechanism sets the detection time and air pressure. After continuously outputting the predetermined air pressure and reaching the preset detection time, the control mechanism controls the air pump 30 to stop outputting gas to the air chamber 212. The drive component 24 drives the second module 23 away from the first module 21. Then, the entire first module 21 is removed or the industrial parts 12 that have been tested are removed, completing the entire testing process. During the testing process, multiple first modules 21 can be prepared. After another first module 21 is filled with the industrial parts 12 to be tested, it is placed on the placement table 15. When the industrial parts 12 of the previous first module 21 have been tested, the previous first module 21 can be removed directly.

[0048] In summary, this utility model places the industrial parts 12 in the testing fixture 20 for testing, eliminating the need to immerse the industrial parts 12 in water for testing. It can test multiple industrial parts 12 simultaneously. Compared with existing testing methods, this application has higher testing efficiency and will not cause contamination to the industrial parts 12 during the testing process. In addition, there is no need to dry the industrial parts 12 after testing, saving process steps.

[0049] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technical aspects of the present utility model shall still fall within the scope of the technical solution of the present utility model.
