[0002] A flow meter is an instrument used to measure the flow of fluid in a pipe or open channel. To ensure the accuracy of the flow meter's measurement data, a sealing performance test is required after the flow meter is manufactured.

[0003] In order to perform sealing tests on flow meters in batches, after searching, a patent publication number "CN213956672U" proposed a vortex flowmeter sealing test device, which mainly sets an annular support platform, an upper pressure seat and a lower pressure seat, and places the flow meter to be tested in the cylindrical mounting groove of the lower pressure seat, and then transports the lower pressure seat with the flow meter to the bottom of the upper pressure seat through the annular support platform, and then fixes the flanges at both ends of the flow meter with the upper and lower pressure seats to seal, and finally ventilates for sealing test.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Reference Figure 1-Figure 8A flow meter sealing detection device includes a workbench 2, a feeding mechanism for conveying the flow meter to be detected is installed on the side wall of the workbench 2, and a discharging mechanism for conveying the flow meter after detection is also installed on the side wall of the workbench 2. The feeding mechanism includes two feeding belt rollers 4, and a feeding conveyor belt 17 is connected between the two feeding belt rollers 4. The two feeding belt rollers 4 are rotatably connected to the side wall of the workbench 2, and a plurality of electromagnetic sheets 35 are installed on the discharging conveyor belt 16. It should be noted that by setting the electromagnetic sheet 35, since the upper and lower flanges of the flow meter 18 are made of iron material, the flow meter falling on the discharging conveyor belt 16 can be adsorbed or released by controlling the power on and off of the electromagnetic sheet 35.

[0033] The discharging mechanism includes two discharging belt rollers 3 , a discharging conveyor belt 16 is connected between the two discharging belt rollers 3 , and the two discharging belt rollers 3 are rotatably connected to the side wall of the workbench 2 .

[0034] A suspension arm 5 is fixedly connected to the side wall of the workbench 2, a servo motor 1 is fixedly installed on the upper end of the suspension arm 5, a rotating shaft 6 is fixedly connected to the output shaft of the servo motor 1, the rotating shaft 6 is rotatably connected to the lower end of the suspension arm 5, an extraction mechanism for extracting the flow meter to be tested is installed at the lower end of the rotating shaft 6, and a detection component for detecting the flow meter is installed at the upper end of the workbench 2.

[0035] Reference Figure 2 The extraction mechanism includes a turntable 7 fixedly connected to the lower end of the rotating shaft 6, a plurality of first cylinders 19 are fixedly connected to the lower end of the turntable 7, a pressing plate 20 is fixedly connected to the telescopic end of each first cylinder 19, a first spring 26 is fixedly connected to the lower end of the pressing plate 20, a bottom plate 24 is fixedly connected to the lower end of the first spring 26, two brackets 23 are fixedly connected to the side wall of the bottom plate 24, and the two brackets 23 are symmetrically arranged along the center of the bottom plate 24, a rotating rod 27 is rotatably connected to the bracket 23, an L-shaped hook plate 28 is fixedly connected to the side wall of the rotating rod 27, a rotating mechanism for rotating the rotating rod 27 is installed on the bracket 23, and an air supply pipe 30 is installed on the side wall of the bottom plate 24; a guide column 25 is fixedly connected to the upper end of the bottom plate 24, and the guide column 25 slides through the pressing plate 20. It should be noted that by setting the guide column 25, the bottom plate 24 can be vertically limited so that the bottom plate 24 can move stably in the vertical direction. The first spring 26 can facilitate the reset of the bottom plate 24 .

[0036] Reference Figure 3 The detection assembly includes a support platform 8 fixedly connected to the upper end surface of the workbench 2, a baffle 9 fixedly connected to the upper end of the support platform 8, a second cylinder 15 fixedly installed on the side wall of the baffle 9, a Z-shaped plate 10 fixedly connected to the telescopic end of the second cylinder 15, an air intake pipe 14 passing through the Z-shaped plate 10, and the air intake pipe 14 and the Z-shaped plate 10 are fixedly connected together, and a bottom cylinder 31 fixedly connected to the upper end of the workbench 2. Specifically, as Figure 8As shown, a vertical groove is provided on the side wall of the bottom cylinder 31. When the flow meter 18 is placed in the bottom cylinder 31, the pressure gauge part of the flow meter 18 can extend through the vertical groove, so that the lower flange of the flow meter 18 can be conveniently fitted with the inner bottom of the bottom cylinder 31.

[0037] Reference Figure 4 The rotating mechanism includes a rack 22 and a gear 29 meshing with each other, wherein the rack 22 slides through the upper end of the bracket 23, the gear 29 is fixedly connected to the rotating rod 27, and the lifting plate 21 is fixedly connected to the side wall of the telescopic rod of the first cylinder 19, and the upper end of the rack 22 is fixedly connected to the lower end of the lifting plate 21. The lifting plate 21 can be driven up and down by the extension and contraction of the first cylinder 19, thereby driving the rack 22 to move. When the positions of the bottom plate 24 and the bracket 23 are fixed, the rack 22 can move relative to the bracket 23, thereby driving the gear 29 to rotate, and finally driving the rotating rod 27 and the L-shaped hook plate 28 to rotate.

[0038] Reference Figure 6 A hollow sealing ring 34 is fixedly connected to the inner wall of the air inlet pipe 14, and a gas cylinder 11 is fixedly connected to the side wall of the boom 5. The gas cylinder 11 is connected to the hollow sealing ring 34 through a gas transmission mechanism. The gas transmission mechanism includes a sealing plug 32, a push rod 12, a second spring 33 and an air guide pipe 13, wherein the sealing plug 32 is sealingly and slidably connected in the gas cylinder 11, one end of the second spring 33 is fixedly connected to the side wall of the sealing plug 32, and the other end of the second spring 33 is fixedly connected to the inner wall of the gas cylinder 11, one end of the gas guide pipe 13 is connected to the gas cylinder 11, and the other end of the gas guide pipe 13 is connected to the hollow sealing ring 34. For details, refer to Figure 6 and Figure 7 As shown, the hollow sealing ring 34 is essentially a circular sealing ring, and is embedded and fixed inside the air intake pipe 14. The interior of the hollow sealing ring 34 is an annular hollow interlayer. The air input by the air guide pipe 13 will be injected into the hollow interlayer and force the hollow sealing ring 34 to bulge. In this way, when the air supply pipe 30 is inserted into the air intake pipe 14 and located in the hollow sealing ring 34, the bulged hollow sealing ring 34 can fit tightly with the air supply pipe 30, which can avoid air leakage from the air intake pipe 14 to the air supply pipe 30, thereby ensuring accurate detection results.

[0039] The push rod 12 is fixedly connected to the side wall of the sealing plug 32, the air inlet end of the air pipe 30 is arranged outside the circumferential side wall of the bottom plate 24, and the air outlet end of the air pipe 30 passes through the side wall of the bottom plate 24 to its lower end surface, and when the bottom plate 24 contacts and seals with the upper end surface of the upper flange of the flow meter 18, the air pipe 30 is just sealed and connected with the inside of the flow meter 18. It should be noted that the air guide pipe 13 adopts a relatively long hose, and when the Z-shaped plate 10 drives the air intake pipe 14 to move left and right, the air guide pipe 13 is relatively long and is a hose, so it can cooperate with the movement of the air intake pipe 14 without being restricted by the air guide pipe 13.

[0040] Reference Figure 6 The push rod 12 and the second spring 33 are respectively arranged on both sides of the sealing plug 32, and the push rod 12 slides through the gas cylinder 11. It should be noted that since the push rod 12 passes through the left side of the gas cylinder 11, the left side of the gas cylinder 11 is connected to the outside, so the sealing plug 32 will not be hindered by the air pressure on the left side when moving.

[0041] In the present invention, Figure 1 As shown, the flow meter to be tested is transported to the right side of the turntable 7 by the feeding conveyor belt 17 on the feeding mechanism. At this time, the first cylinder 19 on the right side of the turntable 7 extends downward. Figure 2 , the telescopic end of the first cylinder 19 will drive the pressing plate 20, the first spring 26 and the bottom plate 24 to move downward. When the bottom plate 24 moves downward to the upper end surface of the upper flange of the flow meter 18, the bottom plate 24 and the upper end surface of the flow meter 18 are attached together. Then the first cylinder 19 continues to push the pressing plate 20 to move downward. Since the bottom plate 24 has been attached to the upper side of the upper flange of the flow meter 18, the bottom plate 24 will no longer move downward, and the bracket 23 fixed on the side wall of the bottom plate 24 will no longer move. When the telescopic rod part of the first cylinder 19 continues to move downward, it will drive the lifting plate 21 to move downward together. At this time, the lifting plate 21 can push the rack 22 to move downward. Figure 4 , the gear 29 in the figure can rotate counterclockwise, thereby driving the rotating rod 27 and the L-shaped hook plate 28 to rotate counterclockwise synchronously. After the L-shaped hook plate 28 rotates, the lower side of the L-shaped hook plate 28 can be hooked on the bottom of the upper flange of the flow meter 18, as shown in FIG. Figure 4 As shown, at this time, the L-shaped hook plate 28 can be clamped and fixed to the upper flange of the flow meter 18 with the bottom plate 24.

[0042] Then the servo motor 1 starts and drives the rotating shaft 6 and the rotating disk 7 to rotate a certain angle, and the clamped flow meter 18 is rotated to the workbench 2, and the flow meter 18 is placed directly above the bottom cylinder 31. Then the first cylinder 19 is moved downward to send the clamped flow meter 18 into the bottom cylinder 31. Figure 5 As shown. (At this time, after the turntable 7 rotates a certain angle, the first cylinder 19 will drive the flowmeter 18 away from the feeding conveyor belt 17, so the bottom of the flowmeter 18 loses support, and at this time, the L-shaped hook plate 28 and the bottom plate 24 have fixed the upper flange of the flowmeter 18, and at this time, the lifting plate 21, the rack 22 and the bracket 23 can move downward synchronously, so the rack 22 and the bracket 23 no longer have relative displacement, and the gear 29, the rotating rod 27 and the L-shaped hook plate 28 will not rotate, so the first cylinder 19 can drive the flowmeter 18 to move downward). When the first cylinder 19 sends the flowmeter 18 into the bottom cylinder 31, the bottom of the bottom cylinder 31 can seal the lower flange of the flowmeter 18, and the pressure applied by the first cylinder 19 can press and fix the flowmeter 18 in the bottom cylinder 31 through the bottom plate 24, and seal the upper and lower ends of the flowmeter 18.

[0043] Reference Figure 5 At this time, the second cylinder 15 is controlled to drive the Z-shaped plate 10 to move to the right, and the Z-shaped plate 10 will drive the air intake pipe 14 to move right together, so that the air delivery pipe 30 on the bottom plate 24 can enter the air intake pipe 14 and make the air delivery pipe 30 located in the hollow sealing ring 34. Then the second cylinder 15 continues to drive the Z-shaped plate 10 to move right, and the Z-shaped plate 10 will gradually release from the push rod 12 and push the push rod 12 to move right together. Figure 6 When the push rod 12 moves to the right, it will also drive the sealing plug 32 in the gas delivery cylinder 11 to move to the right, and the sealing plug 32 can let the air on its right side enter the hollow interlayer of the hollow sealing ring 34 along the air guide pipe 13 (combined with the attached Figure 7 ), the hollow sealing ring 34 will be inflated and bulged, and the inner wall of the hollow sealing ring 34 will be tightly fitted with the outer wall of the air pipe 30, which can avoid air leakage during the air transmission process. Finally, air is input into the air intake pipe 14 through an air injection device with an air pressure display function, such as a digital air pump. The air can enter the air pipe 30 along the air intake pipe 14 and be input to the flow meter 18 through the air pipe 30. At this time, observe and compare the air pressure value input by the air injection device such as the digital air pump and the pressure gauge value of the flow meter 18 to see whether the difference between the two values ​​is within the error range. This can determine whether the flow meter 18 is leaking, and then judge its sealing performance. The entire detection process is automatic and efficient.

[0044] After the detection is completed, the second cylinder 15 is first operated to drive the intake pipe 14 to move left, so that the Z-shaped plate 10 is separated from the push rod 12, and the second spring 33 also pushes the sealing plug 32 to move left and reset, so that the air in the interlayer of the hollow sealing ring 34 can be sucked back, and the hollow sealing ring 34 will shrink accordingly, and no longer tightly adhere to the air supply pipe 30. When the second cylinder 15 continues to drive the intake pipe 14 to move left, the intake pipe 14 can be separated from the air supply pipe 30.

[0045] Subsequently, the first cylinder 19 drives the clamped flow meter 18 to move upward and detach from the bottom cylinder 31, and the servo motor 1 is started again and drives the turntable 7 to rotate a certain angle, so that the first cylinder 19 with the flow meter 18 after the detection can be rotated to the top of the discharge conveyor belt 16 on the left side, and then the first cylinder 19 moves downward again to place the flow meter 18 on the discharge conveyor belt 16, and the flow meter 18 is located on an electromagnetic sheet 35, and then the electromagnetic sheet 35 is energized to generate magnetic attraction and attract the flow meter 18. At this time, the telescopic part of the first cylinder 19 is unable to drive the flow meter 18 to move upward when it contracts, and the lifting plate 21 is at this time. As the first cylinder 19 contracts, it will drive the rack 22 to move upward. At this time, the rack 22 will move relative to the bracket 23, so that the gear 29 rotates in the opposite direction, and simultaneously drives the rotating rod 27 and the L-shaped hook plate 28 to rotate in the opposite direction, so that the L-shaped hook plate 28 is separated from the upper flange of the flow meter 18, thereby automatically releasing the fixation of the flow meter 18. The first cylinder 19 continues to contract and move upward, which can drive the pressure plate 20, the bottom plate 24 and the L-shaped hook plate 28 to separate from the flow meter 18. Then the electromagnetic sheet 35 is powered off and no longer adsorbs the flow meter 18. The flow meter 18 can be transported to the specified position through the discharge conveyor belt 16.

[0046] In summary, the present invention provides a feeding mechanism, a discharging mechanism and a detection component, and the flow meter 18 to be detected is transported by the feeding mechanism to the detection component position for detection. During this process, the extraction mechanism can automatically take the flow meter 18 on the feeding mechanism, and automatically put the flow meter 18 into the bottom cylinder 31 for compression, sealing and fixing. There is no need for operators to take and put the flow meters one by one, which saves manpower and improves efficiency. In addition, the extraction mechanism always fixes the flow meter 18 during the process of taking the flow meter 18, which can effectively avoid the disadvantage of the flow meter 18 falling during the taking process.

[0047] The flow meter 18 is firmly fixed by the bottom plate 24 and the L-shaped hook plate 28. At the same time, the bottom plate 24 and the L-shaped hook plate 28 can be tightly sealed on the upper flange of the flow meter 18, thereby improving the accuracy of the detection; gas can be injected into the gas pipe 30 through the air inlet pipe 14, so that the gas can enter the flow meter 18. By observing the difference between the measured value and the input value of the pressure gauge of the flow meter 18, it can be determined whether the flow meter is leaking, and then its sealing performance can be evaluated. The entire detection process is automatic and efficient; the hollow sealing ring 34 is inflated, thereby improving the sealing effect of the connection between the air inlet pipe 14 and the gas pipe 30, avoiding leakage of the detection component, and ensuring the accuracy of the detection effect.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
