Description

Technical Field

[0001] The present invention relates to the technical field of gas meter manufacturing, and in particular to a gas meter housing air tightness detection device manufactured based on the industrial Internet of Things. Background Art

[0002] During the production process of aluminum-shell gas meters, the air tightness of the upper and lower cavities of the meter body needs to be tested to ensure that the air tightness of the product itself meets the production process requirements. Most traditional gas meter shell detection devices use the air pressure difference detection method, which mainly selects standard parts and test parts for fixation, and simultaneously introduces gas into the standard parts and test parts. The change in the gas pressure difference between the standard parts and the test parts is used to determine whether the air tightness of the test parts is qualified. Although this method can detect the air tightness of the gas meter case, it cannot detect the location of the gas leakage in the gas meter case. Summary of the Invention

[0048] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with examples and drawings. The exemplary embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention. Example

[0049] like Figures 1 to 9 As shown, the present invention includes a detection pool body 40 and a pressure medium generating device, wherein the detection pool body 40 is provided with an upper shell detection component 5 and a lower shell detection component 4; the upper shell detection component 5 and the lower shell detection component 4 both include a sealing unit, and the sealing unit is used to seal the upper shell 7 and the lower shell 6; the pressure medium generating device is used to deliver pressurized gas to the sealed upper shell 7 and the lower shell 6.

[0050] When conducting air tightness testing on existing gas meter cases, the traditional method is to select a standard part and a test part, fix them, introduce gas into the standard part and the test part at the same time, and determine whether the air tightness of the test part is qualified by the change in the gas pressure difference between the standard part and the test part. Although the above method can detect the sealing of the gas meter case, once a leak is detected in the gas meter case, it is impossible to quickly observe the leak location of the case, which makes it difficult to determine what caused the gas meter case to leak during the processing process. To this end, the present technical solution is provided with a detection pool body 40, which is filled with water during detection, and an upper shell detection component 5 and a lower shell detection component 4 are provided in the detection pool body 40. The upper shell detection component 5 is used to detect the upper shell 7 of the gas meter case, and the lower shell detection component 4 is used to detect the lower shell 6 of the gas meter case, which can improve the accuracy of the airtightness detection of the gas meter case; when detecting the upper shell 7 and the lower shell 6, the upper shell 7 and the lower shell 6 are first sealed by using the provided sealing unit to ensure that the interior of the upper shell 7 and the lower shell 6 are in a sealed state at this time, and then water is introduced into the detection pool body 40 of the sealed upper shell 7 and the lower shell 6, and it is ensured that the water introduced into the detection pool body 40 submerges the upper shell 7 and the lower shell 6. Finally, a pressure medium generating device is used to deliver gas with a certain pressure into the sealed upper shell 7 and lower shell 6, and observe whether bubbles are generated in the upper shell 7 and lower shell 6 located in the detection pool body 40. If no bubbles are generated, it is judged that the air tightness of the upper shell 7 and lower shell 6 meets the production requirements; if bubbles are generated in the detection pool body 40, it is judged that there is a gas leakage problem in the upper shell 7 or the lower shell 6, and the position where the bubbles emerge from the upper shell 7 or the lower shell 6 is penetrated to find the gas leakage position of the shell, so as to subsequently determine what causes the gas leakage of the shell. Compared with the traditional air tightness detection method, the detection method of this technical solution is quick and convenient, and it is easy to quickly detect the specific leakage position of the gas meter shell, so as to subsequently summarize the cause of the gas meter shell leakage.

[0051] It also includes a bottom box 1, the pressure medium generating device is located in the bottom box 1, and a water tank is also provided in the bottom box 1.

[0052] The pressure medium generating device in the present technical solution is an air pump, which can generate gas of a certain pressure when working. In this way, the pressure medium generating device can not only provide a certain pressure for the sealing unit when working, ensuring that the sealing unit can fit tightly together with the upper shell 7 and the lower shell 6, thereby ensuring that the upper shell 7 and the lower shell 6 have good airtightness during testing, but also the gas generated by the pressure medium generating device can also be transported to the sealed upper shell 7 and the lower shell 6, so as to determine whether there is a gas leakage problem in the upper shell 7 and the lower shell 6.

[0053] The provided water tank is used to transport water for testing into the testing pool body 40 , so as to ensure that the upper shell 7 and the lower shell 6 can be effectively immersed in the testing pool body 40 during the testing process.

[0054] A support rod 2 is provided on the top of the bottom box 1 , and the detection cell body 40 is located on the support rod 2 .

[0055] The support rod 2 is provided to support the detection cell body 40 .

[0056] The detection pool body 40 is provided with a drain pipe 46 and an overflow pipe 42 , both of which are connected to a water tank. The water tank is also provided with a water inlet pipe 41 , the outlet of which is located above the detection pool body 40 .

[0057] The water required for testing is delivered to the detection tank 40 by means of the water inlet pipe 41, ensuring that the water in the detection tank 40 is always at a high level, thereby ensuring that the upper shell 7 and the lower shell 6 placed in the detection tank 40 are effectively submerged. At the same time, to prevent leakage caused by excessive water entering the detection tank 40, an overflow pipe 42 is provided on the side wall of the detection tank 40. This allows the water entering the detection tank 40 from the water inlet pipe 41 to flow back into the water tank through the overflow pipe 42.

[0058] The sealing unit of the upper shell detection assembly 5 includes a first sealing plate 24, a second sealing plate 30 and a third sealing plate 32. The first sealing plate 24, the second sealing plate 30 and the third sealing plate 32 are respectively used to seal the air outlets of the upper shell 7; the third sealing plate 32 is provided with a first air inlet connected to the pressure medium generating device.

[0059] The upper shell 7 of the gas meter shell is as shown in FIG. Figure 10 As shown, its upper surface has two air inlet holes, and the lower surface and one side thereof have openings connected to the interior. Therefore, in order to ensure that the sealing unit can effectively seal the upper shell 7, the sealing unit includes a first sealing plate 24, a second sealing plate 30 and a third sealing plate 32, wherein the first sealing plate 24 is used to seal the two air inlet holes of the upper shell 7, the second sealing plate 30 is used to seal the opening on the side wall of the upper shell 7, and the third sealing plate 32 is used to seal the opening on the lower surface of the upper shell 7. This ensures that the interior of the upper shell 7 has a certain degree of sealing at this time, thereby ensuring that when the gas generated by the pressure medium generating device enters the interior of the upper shell 7 through the third sealing plate 32, the gas will not leak from the air inlet holes or openings of the upper shell 7 itself, so as to ensure the accuracy of the airtightness detection of the upper shell 7 of the gas meter.

[0060] The upper shell detection assembly 5 also includes a first base plate 25 and a first driving mechanism 29. The first base plate 25 is located in the detection pool body 40. The first driving mechanism 29 is fixed on the first base plate 25. The output end of the first driving mechanism 29 is provided with a first clamping plate 31. The second sealing plate 30 is fixed on the clamping surface of the first clamping plate 31; the first sealing plate 24 is located at the top of the first base plate 25, and a limit member is also provided on the first sealing plate 24.

[0061] In order to ensure that the upper shell 7 to be tested can be stably fixed on the first base plate 25, a limiting member is provided on the first sealing plate 24. When in use, the upper shell 7 is placed upside down on the first sealing plate 24, and the two air inlet holes of the upper shell 7 are sealed by the first sealing plate 24, and the upper shell 7 is limited in the horizontal direction by the limiting member. The first driving mechanism 29 is used to drive the second sealing plate 30 on the first clamping plate 31 to move toward the opening on the side wall of the upper shell 7, and the upper shell 7 is finally fixed on the first base plate 25 with the provided limiting member, and the provided second sealing plate 30 realizes the sealing of the opening on the side wall of the upper shell 7. Therefore, under the joint action of the first driving mechanism 29 and the limiting member, the upper shell 7 to be tested can be stably fixed on the first base plate 25.

[0062] The limiting member includes a support plate 36 and a limiting plate 34. The limiting plate 34 is located on the side of the support plate 36 away from the second sealing plate 30. A bolt 33 is provided on the top of the first bottom plate 25, and the bolt 33 passes through the support plate 36. The support plate 36 is provided with a positioning hole 35 that matches the upper shell 7.

[0063] A vertical rod 38 is further provided on the first bottom plate 25 , and the vertical rod 38 passes through the first bottom plate 25 and the first sealing plate 24 in sequence and is connected to the support plate 36 . An elastic member 37 is further provided between the second sealing plate 24 and the support plate 36 , and the elastic member 37 is sleeved on the vertical rod 38 .

[0064] Since there are two raised air inlet holes on the upper shell 7 in the present technical solution, and the upper shell 7 is in an inverted state during the inspection process, that is, the two air inlet holes on the upper shell 7 are placed inverted on the first sealing plate 24, and the contact area between the two air inlet holes and the first sealing plate 24 is small, while the other two openings of the upper shell 7 that need to be sealed are larger. In order to ensure that the second sealing plate 30 and the third sealing plate 32 can accurately seal the other two larger openings of the upper shell 7, two positioning holes 35 with inner diameters matching the outer diameters of the air inlet holes of the upper shell 7 are provided on the support plate 36. During installation, the two air inlet holes on the upper shell 7 are placed in the positioning holes 35 of the support plate 36, thereby realizing pre-positioning of the upper shell 7 and ensuring that the second sealing plate 30 and the third sealing plate 32 can accurately seal the two larger openings of the upper shell 7.

[0065] At the same time, since the lengths of the two air inlet holes on the upper shells 7 of different batches have a certain normal error range during the processing and manufacturing of the upper shell 7, that is, the lengths of the air inlet holes on the upper shells 7 of different batches are different, in order to ensure that the first sealing plate 24 provided can effectively and accurately seal the two air inlet holes of different lengths of the upper shell 7 within the normal error range, the present technical solution further provides a bolt 33, so that the bolt 33 is sleeved on the support plate 36, and the support plate 36 provided in this way can move axially along the bolt 33, ensuring that the support plate 36 has a certain range of movement in the vertical direction. This design allows the actual testing of upper shells 7 of different batches to be carried out by The support plate 36 provided can have a certain range of motion in the vertical direction. Therefore, the movable support plate 36 can automatically adjust the height according to the length of the air inlet hole of the upper shell 7 of different batches, ensuring that the support plate 36 is set when limiting the upper shells 7 of different batches. The air inlet hole of the upper shell 7 inserted in the positioning hole 35 on the support plate 36 can always be in close contact with the first sealing plate 24, thereby realizing the sealing of the air inlet holes on the upper shells 7 of different batches; the elastic member 37 provided is used to ensure that the support plate 36 is always in contact with the upper shell 7, thereby ensuring that the limiting plate 34 on one side of the support plate 36 can constrain the upper shell 7 in the horizontal direction.

[0066] The lower shell detection assembly 4 includes a fourth sealing plate 19 and two fifth sealing plates 17. The fourth sealing plate 19 and the fifth sealing plate 17 are used to seal the air outlet of the lower shell 6. The fourth sealing plate 19 is provided with a second air inlet connected to the pressure medium generating device.

[0067] The lower shell 6 in this technical solution is as follows Figure 11As shown, interconnected openings are provided on its upper surface and two side walls. In order to ensure that when the airtightness of the lower shell 6 is tested, the gas introduced into the lower shell 6 will not leak through the openings and affect the measurement accuracy of the lower shell 6, the fourth sealing plate 19 is used to seal the opening on the upper surface of the lower shell 6, and the openings on both sides of the lower shell 6 are respectively blocked by two fifth sealing plates 17. At the same time, the second air inlet provided on the fourth sealing plate 19 can be used to introduce gas into the lower shell 6 in a sealed state, and observe whether there is gas leakage in other parts of the lower shell 6, so as to detect the airtightness of the lower shell 6.

[0068] The lower shell detection assembly 4 also includes a second base plate 10 and two second drive mechanisms 8. The second drive mechanisms 8 are located on both sides of the top of the second base plate 10. The output end of the second drive mechanism 8 is provided with a second clamping plate 13, and the fifth sealing plate 17 is located on the clamping surface of the second clamping plate 13; the second base plate 10 is also provided with a limit platform 18 for placing the lower shell 6, and the limit platform 18 is located between the two second drive mechanisms 8.

[0069] In order to ensure that the lower shell 6 to be inspected can be stably fixed on the second base plate 10, two second driving mechanisms 8 are provided on the second base plate 10. When the second driving mechanism 8 is working, it drives the second clamping plate 13 to move toward the opening direction on both sides of the lower shell 6, and finally the fifth sealing plate 17 on the second clamping plate 13 blocks the openings on both sides of the lower shell 6; at the same time, in order to ensure that the fourth sealing plate 19 can accurately block the lower shell 6 fixed on the second base plate 10, a limiting platform 18 is also provided on the second base plate 10. The limiting platform 18 is in a "J" structure. The limiting platform 18 can limit the lower shell 6 in the horizontal direction, ensuring that the lower shell 6 fixed on the second base plate 10 can be in the central position of the second base plate 10, thereby ensuring that the fourth sealing plate 19 can accurately block the opening on the upper surface of the lower shell 6.

[0070] It also includes a top box 3, which is fixed on the top of the support rod 2. Two support frames 39 are provided in the top box 3, and each support frame 39 is provided with a suspension rod 43. The bottom of the suspension rod 43 is provided with a horizontal plate 15; each of the two horizontal plates 15 is provided with a third driving mechanism 14, and the output end of the third driving mechanism 14 is provided with a movable plate 16, and the fourth sealing plate 19 and the third sealing plate 32 are respectively connected to the bottom of the two movable plates 16.

[0071] The upper shell detection component 5 and the lower shell detection component 4 set in the present technical solution are both suspended in the detection pool body 40. This design can avoid the contact between the upper shell detection component 5 and the lower shell detection component 4 and the detection pool body 40, thereby avoiding the dead angle area caused by the connection between the detection component and the detection pool body 40, so as to facilitate the subsequent cleaning of the detection pool body 40. If the upper shell detection component 5 and the lower shell detection component 4 are fixedly installed with the detection pool body 40, this will result in a dead angle area between the upper shell detection component 5 and the lower shell detection component 4 and the detection pool body 40, which is inconvenient to clean the detection pool body 40 after the detection is completed.

[0072] In this technical solution, support columns 12 are also provided on the first base plate 25 of the upper shell detection component 5 and the second base plate 10 of the lower shell detection component 4. The top of the support column is connected to the horizontal plate 15, and the horizontal plate 15 is connected by the set suspension rod 43, so that the upper shell detection component 5 and the lower shell detection component 4 are suspended in the detection pool body 40.

[0073] When the third driving mechanism 14 on the upper shell detection assembly 5 is in operation, it can drive the third sealing plate 32 under the movable plate 16 to move downward, thereby sealing the opening on the lower surface of the upper shell 7 in the inverted state.

[0074] When the third driving mechanism 14 on the lower shell detection assembly 4 is in operation, it can drive the fourth sealing plate 19 under the movable plate 16 to move downward, thereby sealing the opening on the upper surface of the lower shell 6 .

[0075] The movable plates 16 are each provided with an air inlet head 11 , and the two air inlet heads 11 are respectively connected to the first air inlet and the second air inlet.

[0076] In order to allow gas of a certain pressure to be passed into the sealed upper shell 7 and the lower shell 6, an air inlet head 11 connected to the first air inlet and the second air inlet is provided on the movable plate 16. The other end of the air inlet head 11 is connected to a pressure medium generating device. The pressure medium generating device is used to pass gas into the air inlet head 11, thereby achieving the purpose of passing detection gas into the upper shell 7 and the lower shell 6, and finally detecting whether there are bubbles generated on the surface of the upper shell 7 and the lower shell 6 immersed in the detection pool 40.

[0077] The pressure medium generating device is connected to the air inlet head 11 , the first driving mechanism 29 , the second driving mechanism 8 , and the third driving mechanism 14 respectively.

[0078] The pressure medium generating device in the present technical solution is not only used to introduce gas into the upper shell 7 and the lower shell 6 in a sealed state to determine whether bubbles are generated on their surface, thereby realizing the detection of the air tightness of the gas meter shell; at the same time, the first drive mechanism 29, the second drive mechanism 8, and the third drive mechanism 14 are all cylinders, and the set pressure medium generating device can also provide the first drive mechanism 29, the second drive mechanism 8, and the third drive mechanism 14 with the pressure medium required for normal operation, ensuring that the first drive mechanism 29, the second drive mechanism 8, and the third drive mechanism 14 can work normally. Therefore, the present technical solution uses the set pressure medium generating device to not only provide the first drive mechanism 29, the second drive mechanism 8, and the third drive mechanism 14 with the pressure medium required for work, but also provide the upper shell 7 and the lower shell 6 with the pressure gas required for detection, effectively reducing the manufacturing cost and the space occupied by components.

[0079] The support frame 39 is also provided with a driving motor, the output end of the driving motor is connected to the suspension rod 43, and when the driving motor is working, it can drive the suspension rod 43 to rotate, thereby driving the upper shell detection component 5 and the lower shell detection component 4 to rotate on the horizontal plane. Therefore, in the actual detection process, the upper shell detection component 5 and the lower shell detection component 4 suspended in the detection pool body 40 are submerged in the water introduced into the detection pool body 40, and a pressure medium generating device is used to fill a certain pressure of gas into the upper shell 7 and the lower shell 6 in a sealed state, and then the driving motor is used to drive the suspension rod 43 to rotate, and the suspension rod 43 drives the upper shell The detection assembly 5 and the lower shell detection assembly 4 rotate in the detection pool body 40, so that the upper shell 7 and the lower shell 6 can stir the water in the detection pool body 40 during the rotation, so that the upper shell 7 and the lower shell 6 and the water flow continuously roll and rub against each other, so as to achieve the purpose of flushing the surfaces of the upper shell 7 and the lower shell 6. On the one hand, this design can clean the surface of the gas meter shell after casting. On the other hand, when the upper shell 7 and the lower shell 6 rotate in the detection pool body 40, the water waves generated can act on the surfaces of the upper shell 7 and the lower shell 6. In this way, when there are cracks on the surfaces of the upper shell 7 and the lower shell 6 (such as Figure 12As shown), the cracks produced can only cause damage radially inward along the upper shell 7 or the lower shell 6, that is, there are certain cracks 44 on the surface of the upper shell 7 and the lower shell 6, and the inner walls of the upper shell 7 and the lower shell 6 are in a sealed state. In this way, when the gas generated by the pressure medium device is passed into the sealed upper shell 7 and the lower shell 6, since the interior of the upper shell 7 and the lower shell 6 are in a sealed state, the gas passed into the upper shell 7 and the lower shell 6 does not leak and produce bubbles, but there are cracks 44 on the outer surface of the upper shell 7 and the lower shell 6, and the cracks 44 can only expand toward the interior of the upper shell 7 and the lower shell 6. Therefore, the present technical solution cannot detect the above situation by passing gas into the upper shell 7 and the lower shell 6 after the sealed upper shell 7 and the lower shell 6 are immersed in water. Therefore, the present technical solution designs a drive motor, which can drive the upper shell 7 and the lower shell 6 to rotate in the detection pool body 40. Thus, when the upper shell 7 and the lower shell 6 are tested for airtightness, water waves are generated during their rotation. These waves continuously wash the outer surfaces of the upper shell 7 and the lower shell 6, ultimately acting on the crack 44 on the outer surface of the upper shell 7 or the lower shell 6, exerting a force on the crack 44 toward the interior of the upper shell 7 or the lower shell 6, causing the crack 44 to tear the interior of the upper shell 7 or the lower shell 6, ultimately resulting in a crack between the outer surface and the interior of the upper shell 7 or the lower shell 6. At this time, the gas introduced into the interior of the upper shell 7 and the lower shell 6 by the pressure medium generating device can be blown out through this crack and generate bubbles, thereby determining that the gas meter housing is an unqualified product.

[0080] like Figure 13 As shown, the airtightness detection device is configured as an object platform of the intelligent manufacturing industrial Internet of Things. The object platform sends production and manufacturing perception information to the user platform through the sensor network platform, management platform, and service platform that interact in sequence, and receives control information issued by the user platform through the service platform, management platform, and sensor network platform.

It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
