Description

Technical Field

[0001] This utility model belongs to the field of pneumatic component testing technology, specifically relating to a pneumatic component airtightness testing device. 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, pneumatic motors, and steam engines. Pneumatic components must have good airtightness, and during maintenance, it is necessary to test the airtightness of pneumatic components.

[0003] A search revealed that CN218211793U discloses an airtightness testing device for pneumatic components, comprising an upper housing and a lower housing. Both the top two sides of the upper and lower housings have arc-shaped grooves, and air bladders are glued into each groove. An air inlet pipe is provided at one end of each air bladder. Internally threaded tubes are provided on both sides of the bottom of the lower housing. Screws are installed on both top two sides of the upper housing through pre-drilled threaded holes. This utility model discloses an airtightness testing device for pneumatic components, comprising an upper housing and a lower housing. The two systems work together to house the pneumatic component to be tested within the two chambers. The pipes connected to the pneumatic component pass through the two arc-shaped grooves. When the airbag is inflated, it seals the arc-shaped grooves. Therefore, if air bubbles appear in the water inside the upper and lower chambers, it proves that the pneumatic component has poor airtightness and is suitable for widespread promotion and use. However, each time a pneumatic component is tested, the upper and lower chambers need to be opened frequently and then resealed, which is cumbersome and slow, affecting the testing efficiency. Utility Model Content

[0004] (1) Technical problems to be solved To address the shortcomings of existing technologies, the purpose of this utility model is to provide a pneumatic component airtightness testing device. This testing device solves the problem that, under existing technologies, it is necessary to frequently open the upper and lower housings and then reseal them for each pneumatic component being tested, which is a cumbersome and slow operation. Technical solution

[0005] To solve the above-mentioned technical problems, this utility model provides a pneumatic component airtightness testing device. The testing device includes a reaction tank, a support fixedly connected to the middle of the top of the reaction tank, a baffle fixedly connected to the top of the support, a first electric telescopic rod fixedly connected to the outside of the baffle, a support plate fixedly connected to the output end of the first electric telescopic rod, a fixed seat fixedly connected to the top of the support plate, a disc fixedly connected inside the fixed seat, a fixed plate fixedly connected outside the disc, an insertion groove opened in the middle of the fixed plate, a limit groove opened on the surface of the fixed plate, the limit groove and the insertion groove are interconnected, and a pneumatic component is slidably connected inside the insertion groove.

[0006] When using the detection device of this technical solution, the second gear meshes with the first gear, and then the limiting strip rotates. Since the limiting strip is spirally designed, after reacting with the fixed block, the fixed block and the moving block slide. The moving block enters the interior of the insertion slot. After the bottom end of the clamping block contacts the pneumatic component, the extension block at its top end will be directly mounted on the bolt outside the pneumatic component to maintain the clamping force and complete the fixation of the pneumatic component.

[0007] Preferably, a movable block is slidably connected inside the limiting groove, a receiving groove is opened inside the movable block, a clamping block is rotatably connected inside the receiving groove, and an extension block is fixedly connected to the top and bottom of the clamping block.

[0008] Furthermore, a fixed block is fixedly connected to the bottom of the movable block, a first gear is rotatably connected inside the disc, and a receiving plate is fixedly connected to the top of the first gear.

[0009] Furthermore, the receiving plate is fixedly connected to a limiting strip, which has a ring-shaped spiral structure. Multiple sets of limiting strips form a groove, and the fixing block is slidably connected inside the groove.

[0010] Furthermore, a motor is fixedly connected to the outside of the mounting base, and a second gear is fixedly connected to the output end of the motor, which meshes with the first gear.

[0011] Furthermore, a connecting plate is fixedly connected to the inner wall of the reaction tank, and a second electric telescopic rod is fixedly connected inside the connecting plate, extending to the outside of the connecting plate.

[0012] Furthermore, a connector is fixedly connected to the output end of the second electric telescopic rod, and a hose is fixedly connected to the top of the connector. An air pump is fixedly connected to one end of the top of the reaction tank, and the hose extends into the interior of the air pump and is fixedly connected to the air pump.

[0013] Furthermore, a drain pipe is fixedly connected to the bottom of the reaction tank, and the bottom of the inner side of the reaction tank is inclined, with the inclination direction facing the drain pipe.

[0014] (3) Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The detection device of this utility model, through the design of the moving block, causes the second gear to mesh with the first gear, and then the limiting strip rotates. Since the limiting strip is spirally designed, after reacting with the fixed block, the fixed block and the moving block slide together. The moving block enters the interior of the insertion slot. After the bottom end of the clamping block contacts the pneumatic component, the extension block at its top end will be directly mounted on the bolt outside the pneumatic component to maintain the clamping force and complete the fixation of the pneumatic component.

[0015] 2. The detection device of this utility model uses a connector design. The connector is inserted into the pneumatic component. Then, clean water is injected into the reaction tank to submerge the pneumatic component. The air pump outputs gas through a hose to the inside of the connector. By observing whether bubbles are generated in the liquid inside the reaction tank, it can be determined whether there is a problem with the airtightness of the pneumatic component.

[0018] This specific embodiment is a pneumatic component airtightness testing device, the structural schematic diagram of which is shown below. Figure 1-7As shown, the detection device includes a reaction tank 1. A support 2 is fixedly connected to the middle of the top of the reaction tank 1. A baffle 3 is fixedly connected to the top of the support 2. A first electric telescopic rod 4 is fixedly connected to the outside of the baffle 3. A support plate 5 is fixedly connected to the output end of the first electric telescopic rod 4. A fixed seat 6 is fixedly connected to the top of the support plate 5. A disc 7 is fixedly connected inside the fixed seat 6. A fixed plate 8 is fixedly connected to the outside of the disc 7. An insertion groove 9 is opened in the middle of the fixed plate 8. A limiting groove 10 is opened on the surface of the fixed plate 8. The limiting groove 10 and the insertion groove 9 are interconnected. A pneumatic component 901 is slidably connected inside the insertion groove 9. By placing the reaction tank 1 in a designated position, the pneumatic component 901 is inserted into the insertion groove 9 to fix it. Then, the first electric telescopic rod 4 is driven, and the support plate 5 will descend into the inside of the reaction tank 1. At this time, the fixed seat 6 drives the pneumatic component 901 to descend synchronously. In this embodiment, a movable block 11 is slidably connected inside the limiting groove 10. The movable block 11 has a receiving groove inside, and a clamping block 12 is rotatably connected inside the receiving groove. An extension block is fixedly connected to the top and bottom of the clamping block 12. By sliding the movable block 11, the limiting groove 10 will limit the movable block 11, allowing it to move along a predetermined path. The movable block 11 enters the insertion groove 9 and fixes the pneumatic component 901. Then, after the bottom of the clamping block 12 contacts the pneumatic component 901, the clamping block 12 rotates inside the receiving groove. The extension block at its top is directly mounted on the bolt outside the pneumatic component 901 to maintain the clamping force and complete the fixation of the pneumatic component 901. Furthermore, in this embodiment, a fixed block 13 is fixedly connected to the bottom of the moving block 11, a first gear 14 is rotatably connected inside the disc 7, a receiving plate 15 is fixedly connected to the top of the first gear 14, a limiting strip 16 is fixedly connected to the receiving plate 15, the limiting strip 16 has a ring-shaped spiral structure, and a slot is formed between multiple sets of limiting strips 16. The fixed block 13 is slidably connected inside the slot, and a motor 17 is fixedly connected to the outside of the fixed base 6. A second gear 18 is fixedly connected to the output end of the motor 17. The second gear 18 meshes with the first gear 14. By driving the motor 17, its output end generates a motion force on the second gear 18. Then, the second gear 18 meshes with the first gear 14, so that the first gear 14 drives the receiving plate 15 to rotate. Then, the limiting strip 16 rotates. Since the limiting strip 16 has a spiral design, after reacting with the fixed block 13, the fixed block 13 slides. Furthermore, in this embodiment, a connecting plate is fixedly connected to the inner wall of the reaction tank 1. A second electric telescopic rod 19 is fixedly connected inside the connecting plate. The second electric telescopic rod 19 extends to the outside of the connecting plate. A connector 20 is fixedly connected to the output end of the second electric telescopic rod 19. A hose 21 is fixedly connected to the top of the connector 20. An air pump 22 is fixedly connected to one end of the top of the reaction tank 1. The hose 21 extends into the air pump 22 and is fixedly connected to the air pump 22. When the support plate 5 is located inside the reaction tank 1, it is driven by the second electric telescopic rod 19, and its output end extends to allow the connector 20 to be inserted into the pneumatic component 901. Then, clean water is injected into the reaction tank 1 to submerge the pneumatic component 901. At the same time, the air pump 22 is driven, and the air pump 22 outputs gas through the hose 21 to the inside of the connector 20. Whether bubbles are generated in the liquid inside the reaction tank 1 can determine whether there is a problem with the airtightness of the pneumatic component 901. Furthermore, in this embodiment, a drain pipe 23 is fixedly connected to the bottom of the reaction tank 1. The bottom of the inner side of the reaction tank 1 is inclined, and the inclined direction is towards the drain pipe 23. When the detection work is finished, the drain pipe 23 is opened, and the inside of the reaction tank 1 is inclined, so that the liquid always flows towards the drain pipe 23 and is finally discharged to the outside. When using the device of this technical solution, the reaction tank 1 is placed in a designated position, and then the pneumatic component 901 is inserted into the insertion slot 9. The motor 17 is driven, and its output end generates a moving force on the second gear 18. The second gear 18 then meshes with the first gear 14, causing the first gear 14 to drive the receiving plate 15 to rotate. Subsequently, the limiting strip 16 rotates. Because the limiting strip 16 has a spiral design, after reacting with the fixed block 13, the fixed block 13 and the moving block 11 slide. The limiting groove 10 then limits the moving block 11, causing it to move along a predetermined path. The moving block 11 enters the insertion slot 9, fixing the pneumatic component 901. Then, the bottom end of the clamping block 12 contacts the pneumatic component 901, allowing the clamping block 12 to rotate inside the receiving slot. Its top extension block is directly mounted on the bolts outside the pneumatic component 901, maintaining clamping force and completing the pneumatic... After fixing the pneumatic component 901, the first electric telescopic rod 4 is driven, and then the support plate 5 descends into the interior of the reaction tank 1. At this time, the fixed seat 6 drives the pneumatic component 901 to descend synchronously, driven by the second electric telescopic rod 19, whose output end extends so that the connector 20 can be inserted into the interior of the pneumatic component 901. Then, clean water is injected into the interior of the reaction tank 1 to submerge the pneumatic component 901. At the same time, the air pump 22 is driven, and the air pump 22 outputs gas through the hose 21 to the interior of the connector 20. By observing whether bubbles are generated in the liquid inside the reaction tank 1, it can be determined whether there is a problem with the airtightness of the pneumatic component 901. After the test is completed, the drain pipe 23 is opened, and the interior of the reaction tank 1 is tilted so that the liquid always flows towards the drain pipe 23 and is finally discharged to the outside. Compared with the existing pneumatic component airtightness testing device, this utility model can improve the overall practicality of the testing device through design.

[0019] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
