[0038] For the realization of the purpose, functional features and advantages of this application, it will be further described in conjunction with the embodiments and with reference to the attached drawings. Specific embodiments

[0039] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below in conjunction with the attached drawings.

[0040] Please refer to Figures 1 - 8 , the water pump testing tooling proposed by the present invention includes a testing component, a moving device, a sealing component, a machine body 1 and a transmission device 2, wherein:

[0041] The testing component includes a control cabinet 7 and a detector 8. The control cabinet 7 is electrically connected to the detector 8. The detector 8 is used to detect the airtightness of the pump cover, and the control cabinet 7 is used to display the detection result;

[0042] The testing component further includes a diaphragm 14, a fixed seat 13, a side cover 19 and a fixing member 15. The diaphragm 14 is fixed on the top of the fixed seat 13. The fixing member 15 fixes the diaphragm 14 on the top of the base. An air chamber is provided inside the fixed seat 13, and the air chamber is connected to the detector 8 through a pipeline. The side cover 19 is located on one side of the machine body 1 and is movably connected to the machine body 1. One side of the side cover 19 is connected to the detector 8 through a pipeline;

[0043] Inside the diaphragm 14, there are also a coil 22, a sensing member 21 and a spacer 20. The sensing member 21 is located on both sides of the spacer 20 and is attached to the spacer 20. The coil 22 is located outside the sensing member 21 and is attached to the diaphragm 14;

[0044] The transmission device 2 is used to transmit the pump cover;

[0045] The sealing component is located on the top of the fixing frame 6, and the sealing component is used to seal the top of the pump cover.

[0046] In this embodiment, the spacer 20 is made of a soft material, and the sensing member 21 is a flexible thin metal sheet connecting multiple circular magnetic disks. When the sensing member 21 is subjected to the pressure of air pressure, it will bend, and a current will be induced between the magnetic disks and the coil 22. Subsequently, the induced current is received by the control cabinet 7. By sensing through the spacer 20, the sensing member 21, and the coil 22, the stability of the internal air pressure can be monitored. On the one hand, it can detect whether there is a malfunction in the equipment. Secondly, it can cooperate with the control cabinet 7 to jointly monitor the airtightness, with a better detection effect. The detector 8 is a relatively common airtightness detector in the art. The detector 8 can apply air pressure to the sealed space inside the pump cover and the air chamber inside the fixed seat 13 and feed back the air pressure value to the control cabinet 7. The control cabinet 7 can display the air pressure value of the detector 8. The detector 8 can pressurize the bottom of the pump cover and the fixed seat 13. The side cover 19 can seal the pump cover from the side. The detector 8 can apply air pressure to the gas from one side of the fixed seat 13 and the sealed space inside the water pump through a pipeline, and then compare it with the air pressure value displayed by the control cabinet 7. If the air pressure values inside the air chamber of the fixed seat 13 and inside the pump cover are the same or have not changed, it means that the airtightness of the pump cover is qualified. If the air pressure value inside the pump cover changes, it indicates that the airtightness of the pump cover is unqualified. The sealing component can be pressed down to seal the top of the pump cover. At the same time, it can also press down the pump cover and press the pump cover tightly onto the fixed seat 13 of the test component. By simultaneously pressurizing the air chamber inside the fixed seat 13 and the space inside the sealed pump cover, it is possible to test the airtightness inside the pump cover without applying a large pressure.

[0047] In this embodiment, the sealing component includes an elastic member 10, an upper cover 9, a first cylinder 12, and fixing columns 11. There are multiple fixing columns 11. The fixing columns 11 are movably connected to the upper cover 9. One end of the elastic member 10 is fixedly connected to the fixing columns 11, and the other end of the elastic member 10 is fixedly connected to the upper cover 9. The output end of the first cylinder 12 is fixedly connected to the upper cover 9. The first cylinder 12 is fixed to the top of the machine body 1. The first cylinder 12 is used to drive the upper cover 9 to move longitudinally. A rubber ring 16 is provided at the bottom of the fixing column 11. The rubber ring 16 is fixedly connected to the fixing column 11. The rubber ring 16 is used to buffer the pressure of the fixing column 11 on the pump cover.

[0048] During specific implementation: The rubber ring 16 at the bottom of the fixing column 11 can reduce the friction between the fixing column 11 and the top of the pump cover and prevent damage to the pump cover when the fixing column 11 is pressed down. When the first cylinder 12 drives the upper cover 9 to move downward, the rubber ring 16 at the bottom of the fixing column 11 first contacts the top of the pump cover, and then the elastic member 10 buffers the excess pressure. The upper cover 9 drives the fixing column 11 to fit the top of the pump cover, thereby completing the sealing of the top of the pump cover.

[0049] In this embodiment, the test assembly further includes a second cylinder 17 located on one side of the machine body 1 , and the second cylinder 17 is used to push the side cover 19 to seal the side of the pump cover.

[0050] During specific implementation: the second cylinder 17 can push the side cover 19 to move and fit the side air inlet of the pump cover. After fitting, the detector 8 can ventilate the inside of the side cover 19 to apply air pressure to the enclosed space inside the pump cover, thereby testing the air tightness of the pump cover.

[0051] In this embodiment, the moving device includes a fixing frame 6 and a driving assembly. The fixing frame 6 is provided with a plurality of protrusions, and the protrusions are used to lift and drive the pump cover to move.

[0052] The pump cover is moved to the conveying device 2 on the right side. Through the reciprocating movement of the fixed frame 6 to the right, the pump cover can be transported to the right, thereby completing the automatic fixation and removal of the pump cover.

[0053] In this embodiment, the drive assembly is used to drive the fixed frame 6 to move. The drive assembly includes a transverse mechanism 4 and a longitudinal mechanism 3. The transverse mechanism 4 is used to move the fixed frame 6 laterally, and the longitudinal mechanism 3 is used to move the fixed frame 6 longitudinally. The drive assembly also includes a sliding ring 5. The output ends of the transverse mechanism 4 and the longitudinal mechanism 3 are fixedly connected to the sliding ring 5, and the sliding ring 5 is movably connected to the fixed frame 6.

[0054] In the specific implementation: the transverse mechanism 4 and the longitudinal mechanism 3 can push the fixed frame 6 to move longitudinally and transversely through the sliding ring 5, and the sliding ring 5 and the fixed frame 6 can jointly complete the moving fixed frame 6 of the square trajectory. The longitudinal mechanism 3 and the transverse mechanism 4 can be cylinders or other mechanisms that can move linearly, such as motor screws.

[0055] In this embodiment, the transmission device 2 is used to transport the inspected and uninspected pump covers, and the transmission device 2 is located on both sides of the machine body 1 .

[0056] In specific implementation: The transmission device 2 can be a conveyor belt or other devices capable of transporting the pump cover. At the end of the transmission device 2, there is a monitor that can detect the position of the water pump cover. The water pump can just fall on the top of the fixing frame 6 through the transmission device 2. The transmission device 2 can transport the untested pump cover to the top of the fixing frame 6, or transport the tested pump cover to the top of the conveyor belt.

[0057] In this embodiment, the water pump testing system includes an acquisition module 50, a data recognition module 60, an induction module 70, and a control module 40. Among them: The acquisition module 50 is used to acquire the detected air pressure value. The induction module 70 includes a vision camera 18 arranged at the bottom of the upper cover 9. The induction module 70 is used to sense whether the water pump is located on the fixing seat 13. The control module 40 is used to drive the lateral mechanism 4, the longitudinal mechanism 3, the first cylinder 12, the transmission device 2, and the second cylinder 17 to move. The data recognition module 60 is used to compare and identify the air pressure value.

[0058] In specific implementation: The acquisition module 50 can be used to acquire the input air pressure value. The vision camera 18 of the induction module 70 can sense whether the water pump is located on the fixing seat 13. The control module 40 can control the lateral mechanism 4 and the longitudinal mechanism 3 to move the pump cover, control the normal operation and transportation of the detection tooling. The induction module 70 senses whether the water pump cover has moved to the top of the fixing seat 13. When it moves to the top of the fixing seat 13, the control module 40 drives the second cylinder 17 and the first cylinder 12 to seal the pump cover. Then, the detector 8 injects gas. At the same time, the acquisition module 50 acquires the air pressure of the pump cover, and the data recognition module 60 of the control cabinet 7 displays the air pressure value.

[0059] In this embodiment, the water pump testing method includes the following steps:

[0060] S1. Place the water pump on the transmission device 2, and the lateral mechanism 3 and the longitudinal mechanism 4 drive the fixing frame to move the pump cover to the fixing seat.

[0061] S2. The first cylinder 12 and the second cylinder 17 drive the upper cover and the side cover to seal the pump cover and fix the pump cover to the fixing seat at the same time.

[0062] S3. The detector 8 simultaneously applies air pressure to the sealed space and the air chamber inside the water pump cover, and the control cabinet displays the air pressure value.

[0063] S4. Compare the air pressure in the air chamber and the sealed space. If the air pressure values are the same and do not change, it indicates that the pump cover has qualified sealing performance.

[0064] In specific implementation: By comparing the air pressure values in the air chamber and the sealed space, the test result can be made more accurate. At the same time, without applying a large air pressure, the sealing performance of the pump cover can be detected.

[0065] In summary, during specific implementation, sealing rings are provided inside the part of the upper cover 9 close to the top of the pump cover and the part of the seal close to the side of the pump cover. The water pump is placed on the transmission device 2 on the left side and conveyed to the top of the first position of the fixing bracket 6. The fixing bracket 6 moves upward, rightward, and downward to the top of the fixing seat 13 through the longitudinal mechanism 3 and the transverse mechanism 4, and then moves leftward again. After moving leftward, the second position of the fixing bracket 6 is aligned with the bottom of the pump cover. Subsequently, the first cylinder 12 drives the upper cover 9 to seal the top of the pump cover, the second cylinder 17 drives the side cover 19 to move and seals the pump cover, and the detector 8 simultaneously applies air pressure to the air chamber inside the fixing seat 13 and the inside of the sealed pump cover. After applying the air pressure, the air pressure result is displayed on the control cabinet 7 to display the detection result.

[0066] Certainly, the present invention may also have many other implementation manners. Based on this implementation manner, other implementation manners obtained by those of ordinary skill in the art without any creative work belong to the scope protected by the present invention.
