Description

An electronic water pump air tightness detection device Technical Field

[0001] The present invention relates to the technical field of airtightness detection, and in particular to an airtightness detection device for an electronic water pump. Background Art

[0002] In order to prevent the three leakage problems of "air leakage, water leakage and oil leakage" of electronic water pumps, air tightness detection is required during the manufacturing process of electronic water pumps. For example, the publication number CN204255586U proposes a utility model patent for a water pump air tightness detection device. A second pressing device for pressing the water outlet of the water pump is provided at the water outlet of the water pump. Under the action of the second pressing device, the water outlet of the water pump is sealed; and an air inlet hole connected to the inner cavity of the water pump is provided on the fixed bottom plate. The inner cavity of the water pump is connected to a pressure gauge, and gas at one end pressure is filled into the inner cavity of the water pump. The pressure gauge value is observed to see whether it changes within a specified time. If the pressure gauge value is stable, it means that the air tightness of the water pump is qualified.

[0003] However, the detection equipment of the above patent can only be used for the detection of two-hole electronic water pumps, and the water inlet pipe and the water outlet pipe are both perpendicular to the impeller box. For electronic water pumps of different models, and the water inlet pipe or the water outlet pipe is tilted on the impeller box, it is necessary to replace the corresponding detection tooling. Otherwise, due to the angle problem, the sealing of the connection between the sealing head and the water inlet pipe or the water outlet pipe cannot be guaranteed, thereby affecting the airtightness detection result. Since the existing detection equipment is not universal, it is necessary to replace the detection work for different models of electronic water pumps, which leads to reduced detection efficiency.

[0055] As shown in Figures 1 to 7, an electronic water pump airtightness detection device includes a workbench 1, a placement table 2 and an annular displacement assembly arranged around the placement table 2 on the top of the workbench. The annular displacement assembly is provided with three posture adjustment assemblies, each of which is provided with a telescopic member 3. One of the telescopic members 3 is provided with an inflation joint 4, and the other telescopic members 3 are provided with a detection joint 5. The annular displacement assembly includes:

[0056] A first mounting ring 6 is mounted on the workbench 1;

[0057] A second mounting ring 7 is mounted inside the first mounting ring 6;

[0058] A third mounting ring 8 is mounted inside the second mounting ring 7;

[0059] A first driving member is mounted on the top of the workbench 1 and is in transmission connection with the first mounting ring 6;

[0060] A linkage assembly is provided at the bottom of the first mounting ring 6, and is used to cooperate with the first mounting ring 6 to respectively drive the second mounting ring 7 and the third mounting ring 8 to rotate;

[0061] Among them, the posture adjustment component corresponding to the inflation joint 4 is installed on the first mounting ring 6, and the posture adjustment components corresponding to the detection joint 5 are installed on the second mounting ring 7 and the third mounting ring 8 respectively.

[0062] For example, by placing the electronic water pump in any state on the placement table 2, the first driving member drives the first mounting ring 6 to rotate, and the linkage component cooperates with the first mounting ring 6 to make the first mounting ring 6 drive the second mounting ring 7 and the third mounting ring 8 to rotate through the linkage component, first drive the posture adjustment component to move to the electronic water pump interface through the third mounting ring 8, and the posture adjustment component works to make the telescopic member 3 drive the detection connector 5 to adjust the height and angle according to the angle of the electronic water pump interface, and drive the detection connector 5 to be put on the electronic water pump interface through the telescopic member 3 to complete the sealing connection. When one is completed, After the detection joint 5 is sealed, the linkage component is adjusted to only drive the second mounting ring 7 to rotate, so that the detection joint 5 on the second mounting ring 7 is sleeved on the other interfaces of the electronic water pump to complete the sealed connection. Finally, the linkage component is reset, and only the first mounting ring 6 is left to rotate, so that the inflation joint 4 on the first mounting ring 6 is sleeved on the last interface of the electronic water pump. The electronic water pump is inflated through the inflation joint 4, and the airtight instrument connected to the detection joint 5 works, thereby completing the airtightness detection of the electronic water pump, solving the problem that the existing electronic water pump airtightness detection equipment has poor versatility and reduces the detection efficiency.

[0063] As an optional embodiment, the placement table 2 is provided with a clamping assembly, and the clamping assembly includes:

[0064] A second driving member is arranged inside the placement table 2;

[0065] Two connecting bars 9 are respectively provided on one side of the second driving member, each of the connecting bars 9 is in driving connection with the second driving member, and each of the connecting bars 9 is provided with a spur rack 10 on the side, and each of the spur racks 10 is in sliding connection with the inner wall of the placement table 2;

[0066] Two splints 11 are respectively arranged on the side of the connecting bar 9 away from the second driving member, and a mounting bar 12 is provided next to each splint 11. One end of each mounting bar 12 is fixedly connected to one side of the placement table 2, and the other end extends downward and is hinged to one end of the splint 11. A first gear 13 is provided on the side of each mounting bar 12 away from the splint 11, and each first gear 13 is fixedly connected to the splint 11, and each first gear 13 is respectively engaged with the spur rack 10.

[0067] As an optional embodiment, the second driving member includes:

[0068] A first motor 14 is mounted inside the placement table 2;

[0069] A disc 15 is provided between the two connecting bars 9 and is fixedly connected to the output shaft of the first motor 14;

[0070] Two slide rails 16 are respectively provided on one side of the connecting bar 9 close to the disc 15, and each of the slide rails 16 is fixedly connected to the connecting bar 9;

[0071] Two sliders 17 are respectively slidably connected to the slide rails 16;

[0072] One end of the two connecting arms 18 is hinged to the slider 17 respectively, and the other end is fixedly connected to the disc 15.

[0073] For example, when the electronic water pump is placed on the placement table 2, the first motor 14 drives the disc 15 to rotate, and the disc 15 drives one end of the connecting arm 18 to move, so that the other end of the connecting arm 18 moves on the slide rail 16 through the slider 17, thereby pushing the connecting bar 9 to move, and the connecting bar 9 drives the spur rack 10 to move, and the spur rack 10 drives the first gear 13 to rotate, and the first gear 13 drives one end of the splint 11 to rotate on the mounting bar 12, so that the splint 11 moves close to the placement table 2, thereby clamping the electronic water pump, thereby achieving the work of fixing the electronic water pump.

[0074] As an optional embodiment, a plurality of clamping blocks 19 are provided on the clamping side of the clamping plate 11, each of the clamping blocks 19 is fixed with a guide rod 20 passing through the clamping plate 11, each of the guide rods 20 is sleeved with a first spring 21, and the two ends of each first spring 21 respectively press against the clamping plate 11 and the clamping block 19.

[0075] For example, since the electronic water pump can be placed on the placement table 2 at will, the clamp 11 is clamped at the irregular parts of the electronic water pump, which is unstable. By arranging a clamping block 19, a guide rod 20 and a first spring 21 on the clamping plate 11, and utilizing the elasticity of the first spring 21, the irregular parts are squeezed by the clamping block 19, and the clamping block 19 squeezes the first spring 21, thereby avoiding the irregular parts and further enabling the clamping plate 11 to cope with electronic water pumps placed in various postures.

Among them, the cylinders corresponding to the first mounting ring 6 and the second mounting ring 7 are parallel to the screw slide 22 during the rotation process to prevent the cylinder from colliding with other screw slides 22.

[0079] As an optional embodiment, the bottoms of the first mounting ring 6, the second mounting ring 7 and the third mounting ring 8 are each provided with an annular groove 24, and the interior of each annular groove 24 is provided with at least four slidingly connected limit blocks 25, and each limit block 25 is provided with a downwardly extending support rod 26, and each support rod 26 is fixedly connected to the workbench 1 so that the first mounting ring 6, the second mounting ring 7 and the third mounting ring 8 can rotate on the workbench 1.

[0080] As an optional embodiment, the first driving member includes:

[0081] a first annular rack 27, sleeved on the first mounting ring 6, and the first annular rack 27 is fixedly connected to the first mounting ring 6;

[0087] A third annular rack 31 is fixed to the bottom of the second mounting ring 7;

[0089] A third gear 33 is provided between the second annular rack 30 and the third annular rack 31 , and a first shaft 34 is fixedly provided downwardly from the center of the third gear 33 ;

[0090] A sleeve 35 is sleeved on the first shaft 34. The sleeve 35 and the first shaft 34 are slidably connected via a key 36. A second spring 37 is provided inside the sleeve 35, and two ends of the second spring 37 respectively abut against the sleeve 35 and the first shaft 34.

[0091] A fourth gear 38 is disposed between the third annular rack 31 and the fourth annular rack 32 , and a second shaft 39 is fixedly provided downwardly extending from the center of the fourth gear 38 ;

[0095] At least one limiting rod 43 is provided on the connecting plate 40, and one end of the limiting rod 43 is fixedly connected to the workbench 1;

[0096] The third gear 33 is driven by the single-axis cylinder 42 and meshes with the second annular rack 30 and the third annular rack 31 . The fourth gear 38 is driven by the single-axis cylinder 42 and meshes with the fourth annular rack 32 .

[0097] For example, when the position of the detection joint 5 and the inflation joint 4 needs to be adjusted, the connecting plate 40 is driven upward by the single-axis cylinder 42, and the sleeve 35 and the second shaft 39 are driven upward by the connecting plate 40. The sleeve 35 drives the first shaft 34 to move upward through the second spring 37, so that the first shaft 34 drives the third gear 33 to engage with the second annular rack 30 and the third annular rack 31 first, and continues to move upward through the connecting plate 40, so that the first shaft 34 squeezes the second spring 37, so that the first shaft 34 is compressed into the sleeve 35. At this time, the second shaft 39 drives the fourth gear 38 to engage with the fourth annular rack 32, drives the second annular rack 30 to rotate through the first mounting ring 6, drives the third gear 33 to rotate through the second annular rack 30, drives the first shaft 34 to rotate through the third gear 33, and the first shaft 34 drives the sleeve 35 to rotate through the key 36.

Afterwards, the single-axis cylinder 42 contracts a part to disengage the fourth gear 38 from the fourth annular rack 32. At this time, only the second mounting ring 7 and the first mounting ring 6 rotate. By determining the electronic water pump interface corresponding to the detection connector 5 on the second mounting ring 7, the sealing work of the second interface on the electronic water pump is completed. Finally, the single-axis cylinder 42 is reset, and only the first mounting ring 6 rotates to determine the position of the last interface on the electronic water pump to complete the sealing work, so that the airtightness detection work can be carried out to know whether the airtightness of the electronic water pump is qualified.
