Description

Technical Field

[0001] This utility model relates to the field of pneumatic component testing technology, specifically a testing device for pneumatic components. Background Technology

[0002] Pneumatic components are devices that perform work by using the force generated by the pressure or expansion of gas. They are machine parts that convert the elastic energy of compressed air into kinetic energy, such as cylinders and pneumatic motors. Pneumatic components are a form of power transmission and also an energy conversion device that uses gas pressure to transmit energy. After production, pneumatic components need to undergo leakage testing. This is done by spraying soapy water onto the pneumatic components to observe whether they leak. A testing device for pneumatic components is needed.

[0003] Existing testing devices have several shortcomings. They typically lack the function of automatically preparing soapy water, making it impractical to stir and prepare the necessary soapy water for testing. Furthermore, they cannot perform rotational testing, compromising the accuracy and comprehensiveness of test results and hindering the effective detection of potential leaks. Additionally, they cannot rinse the surfaces of pneumatic components with water, leaving residual alkaline soapy water that can corrode the components. This residue can also dry and leave behind inconspicuous residue in the internal channels or orifices of the pneumatic components, affecting their normal operation. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are: the testing device for pneumatic components not only enables the preparation of soapy water required for testing by stirring during use, making the testing device more practical, ensuring the accuracy and comprehensiveness of test results, and more effectively identifying potential leaks, but also prevents residual alkaline soapy water from corroding the surface of the pneumatic components and avoids residues left in the internal channels or small holes of the pneumatic components after the soapy water dries, thus affecting the normal use of the pneumatic components;

[0015] 1. By setting up an automatic preparation mechanism, the drive motor inside the motor box is controlled to work. Under the action of the drive motor, the shaft rotates, and the shaft drives the stirrer to rotate inside the soap water tank. Under the action of the stirrer, the stirring rod rotates inside the soap water tank. Under the combined action of the stirrer and the stirring rod, the water and soap solution inside the soap water tank can be fully stirred and mixed to prepare soap water, which is used to prepare for the testing of pneumatic components. This realizes the function of automatically preparing soap water in the testing device, so that the testing device can stir and prepare the soap water required for the test, making the testing device more practical in use.

The rotating shaft drives the driving pulley to rotate on the inner wall of the container. The driving pulley drives the belt body to rotate. Under the action of the belt body, the driven pulley drives the driven pulley to rotate inside the container. The driven pulley drives the rotating column to rotate on the inner wall of the container. When the rotating column rotates, it can drive the turntable and the test box to rotate on the surface of the test platform, thereby rotating the angle of the pneumatic components clamped on the surface of the test platform. This realizes the function of rotating testing of the testing device, so that the testing device can ensure the accuracy and comprehensiveness of the test results when used, and can more effectively find potential leaks.

[0017] 3. By incorporating a clean water rinsing mechanism, clean water is added to the clean water tank through the inlet pipe. Under the action of the second liquid level sensor, the water level inside the clean water tank is monitored in real time to prevent excessive water overflow. Under the action of the second water pump, the clean water inside the clean water tank is sucked out and introduced into the drain pipe. The clean water enters the inlet pipe through the drain pipe, and then enters the lead pipe through the inlet pipe. It is then sprayed out through the nozzle to rinse the soap solution on the surface of the pneumatic components clamped on the platform. This realizes the clean water rinsing function of the testing device, thereby preventing residual alkaline soap solution from corroding the surface of the pneumatic components during use, and preventing residues left in the internal channels or small holes of the pneumatic components after the soap solution dries, which would affect the normal use of the pneumatic components.

[0026] During implementation, the rotating motor 25 inside the holding box 21 is controlled to work. Under the action of the rotating motor 25, the rotating shaft 24 is driven to rotate. When the rotating shaft 24 rotates, the rotating shaft 24 drives the driving pulley 23 to rotate on the inner wall of the holding box 21.

[0027] Furthermore, such as Figure 2 and Figure 3As shown, the soap water tank 14 is equipped with an automatic preparation mechanism 3. The automatic preparation mechanism 3 includes a drive motor 31, a motor housing 32, a shaft 33, stirring rods 34, and a stirrer 35. The soap water tank 14 is equipped with a stirrer 35 for mixing and stirring water and soap solution. The stirrer 35 rotates and engages with the inner wall of the soap water tank 14. Multiple sets of stirring rods 34 are arranged on the surface of the stirrer 35 in a circumferential array. The motor housing 32 is installed on the surface of the top center position of the soap water tank 14. The drive motor 31 is installed inside the motor housing 32. The model of the drive motor 31 can be selected from the JO series. The input end of the drive motor 31 is electrically connected to the output end of the controller 11.

[0028] During implementation, the drive motor 31 inside the control motor box 32 operates, driving the shaft 33 to rotate.

[0029] Furthermore, such as Figure 2 and Figure 3 As shown, a clean water rinsing mechanism 4 is provided on the surface of the test bench 1 and the water inlet pipe 18. The clean water rinsing mechanism 4 includes a drain pipe 41, a second water pump 42, a water inlet pipe 43, a water inlet cylinder 44, a clean water tank 45, and a second liquid level sensor 46. A clean water tank 45 is installed on the surface at the top of the test bench 1, and a water inlet cylinder 44 is installed on the surface at the top of the clean water tank 45. The water inlet cylinder 44 is connected to the interior of the clean water tank 45. The inner wall of the soap water tank 14 is equipped with a second liquid level sensor 46. The model of the second liquid level sensor 46 can be selected from the HS series. The output end of the second liquid level sensor 46... The water inlet pipe 43 is installed on the surface of the water inlet pipe 18, which is electrically connected to the input terminal of the controller 11. The water inlet pipe 43 is connected to the interior of the water inlet pipe 18. A second water pump 42 is installed on the surface at the top of the test bench 1. The model of the second water pump 42 can be SLG series. The input terminal of the second water pump 42 is electrically connected to the output terminal of the controller 11. The input terminal of the second water pump 42 extends into the interior of the clean water tank 45. A drain pipe 41 is installed on the output terminal of the second water pump 42. The drain pipe 41 is connected to the water inlet pipe 43 by bolts. The drain pipe 41 is connected to the interior of the water inlet pipe 43.

[0030] During implementation, clean water is added to the clean water tank 45 through the water inlet cylinder 44. Under the action of the second liquid level sensor 46, the water level inside the clean water tank 45 is monitored in real time to avoid excessive water overflow. After the electric component test is completed, the user operates the controller 11 to control the second water pump 42 to work. Under the action of the second water pump 42, the clean water inside the clean water tank 45 is sucked out and introduced into the drain pipe 41. The clean water enters the water inlet pipe 43 through the drain pipe 41, and then enters the water inlet pipe 18 through the water inlet pipe 43. It is then sprayed out through the nozzle 17 to rinse the soap solution on the surface of the pneumatic component clamped on the surface of the placement platform 114, so as to realize the function of clean water rinsing of the test device.

[0031] Working Principle: In use, the test platform 1 is first placed in the designated position. Water and soap solution are added to the soap water tank 14 through the inlet cylinder 19. After the water and soap solution enter the soap water tank 14, the liquid level inside the soap water tank 14 is monitored in real time by the first liquid level sensor 115 on the inner wall of the soap water tank 14. Subsequently, the controller 11 controls the drive motor 31 inside the motor housing 32 to work. Under the action of the drive motor 31, the shaft 33 rotates. When the shaft 33 rotates, it drives the stirrer 35 to rotate inside the soap water tank 14. Under the action of the stirrer 35, the stirring rod 34 rotates inside the soap water tank 14. Under the combined action of the stirrer 35 and the stirring rod 34, the water and soap solution inside the soap water tank 14 are thoroughly stirred and mixed to prepare soap water, preparing for the testing of pneumatic components. This realizes the function of automatically preparing soap water for the testing device, enabling the testing device to prepare the soap water required for testing, making the testing device more practical in use.

[0032] Subsequently, the user places the pneumatic component to be tested on the surface of the placement platform 114 inside the test chamber 13. Under the elastic force of the spring device 112 on the surface of the fixed seat 16, the clamping plate 113 moves. Under the combined action of the spring device 112 and the clamping plate 113, the pneumatic component is clamped on the surface of the placement platform 114. During the test, it is necessary to ensure that the air source is turned on and the pressure is stable. Then, the controller 11 controls the first water pump 110 inside the pump box 111 to work. Under the action of the first water pump 110, soapy water is pumped out. The soapy water inside the chamber 14 is drawn into the water inlet pipe 18 and sprayed into the test chamber 13 through the nozzle 17. The pneumatic components clamped on the surface of the platform 114 are sprayed for testing. The soapy water is sprayed onto the air pipe joint of the pneumatic component, and the presence of bubbles is carefully observed. If bubbles are present, it indicates a leak. The soapy water is also sprayed around the cylinder wall of the pneumatic component, and the presence of bubbles is observed. If bubbles are present, it indicates a leak. After the test is completed, the soapy water inside the test chamber 13 is discharged through the drain assembly 15.

[0033] Subsequently, to ensure the soapy water reaches all parts of the pneumatic components more evenly, including hard-to-observe gaps or interfaces, the user operates the controller 11. This controller 11 then controls the rotating motor 25 inside the container 21. The rotating motor 25 drives the rotating shaft 24 to rotate. When the rotating shaft 24 rotates, it drives the drive pulley 23 to rotate on the inner wall of the container 21. The drive pulley 23, in turn, drives the belt body 28 to rotate, which in turn drives... Driven pulley 22 rotates inside container 21. When driven pulley 22 rotates, it drives rotating column 27 to rotate on the inner wall of container 21. When rotating column 27 rotates, it drives turntable 12 and test box 13 to rotate on the surface of test platform 1, thereby rotating the angle of pneumatic components clamped on the surface of placement platform 114 to realize the function of rotational testing of the testing device. This ensures the accuracy and comprehensiveness of test results when the testing device is used, and can more effectively detect potential leaks.

[0034] Subsequently, clean water is added to the clean water tank 45 through the water inlet tube 44. Under the action of the second liquid level sensor 46, the water level inside the clean water tank 45 is monitored in real time to prevent excessive water overflow. After the electric component test is completed, the user operates the controller 11 to control the second water pump 42 to work. Under the action of the second water pump 42, the clean water inside the clean water tank 45 is sucked out and introduced into the drain pipe 41. The clean water enters the inlet pipe 43 through the drain pipe 41, and then enters the water inlet pipe 18 through the inlet pipe 43. It is sprayed out through the nozzle 17 to rinse the soap solution on the surface of the pneumatic component clamped on the surface of the platform 114, so as to realize the function of clean water rinsing of the test device. This prevents the residual alkaline soap solution from corroding the surface of the pneumatic component during the use of the test device, and prevents the soap solution from drying and leaving residue in the internal channels or small holes of the pneumatic component, which would affect the normal use of the pneumatic component. The rinsed water is discharged into the test chamber 13 through the drain assembly 15, and the use of the test device is finally completed.
