Technical Field

[0001] This utility model relates to the field of sealing sleeve technology, specifically to a sealing sleeve and housing assembly tooling. Background Technology

[0002] The pump body of an electronic water pump is usually composed of an injection-molded housing and a top cover housing, which are equipped with a rotor and a thrust ring. When the injection-molded housing and the top cover housing are connected, they are usually connected by driving multiple self-tapping screws into the corresponding screw holes. Before connecting the self-tapping screws, a sealing ring needs to be placed at the connection point of the pump body to ensure a tight seal assembly of the pump body. Improving the assembly yield of the pump body is a major problem that the industry wants to solve.

[0003] Prior art 1 (application number: CN202322000575.0) discloses a water pump assembly device, including a workbench. A sealing ring assembly fixture and a nailing fixture are provided on the workbench. The sealing ring assembly fixture is located on one side of the workbench and is used for installing the sealing ring. The nailing fixture is used to fix and assemble the pump body. The sealing ring assembly fixture is used to automatically assemble the sealing ring, allowing it to be smoothly assembled into the sealing ring groove of the injection-molded housing and to fit tightly against the housing, ensuring the sealing performance of the electronic water pump. The nailing fixture is used to fix the housing and drive in self-tapping screws. First, the injection-molded housing with the installed sealing ring and the water pump cover are assembled and pressed together using product assembly components. Then, the screw setting component drives the self-tapping screws into the screw holes to complete the pump housing assembly, thereby improving the assembly yield of the electronic water pump.

[0004] However, during the implementation of the relevant technology, the following problems were found in the above-mentioned water pump assembly equipment: when assembling the sealing sleeve and the housing, misalignment is likely to occur, affecting the tightness of the assembly.

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0030] Please see Figures 1-4 This utility model provides a tooling solution for assembling a sealing sleeve and a housing: including a body 1, a push-button switch 2, a first electric telescopic rod 3, a housing locking block 4, a support plate 5, a bracket 6, a second electric telescopic rod 7, a limiting side plate 8, a limiting front plate 9, an anti-detachment structure 10, a sleeve 1001, an elastic sheet 1002, a protective sheet 1003, a mounting plate 11, a third electric telescopic rod 12, a sealing ring body 13, a housing body 14, a limiting hole 15, and a limiting plate 16.

[0031] The working principle and usage process of this utility model are as follows: First, combined with... Figure 1 , Figure 2 and Figure 4 As shown, the length of the support plate 5 is greater than the diameter of the limiting hole 15, and the diameter of the limiting hole 15 is less than the length of the housing block 4. The front and rear outer surfaces of the housing block 4 are in contact with the inner wall of the limiting plate 9, and the left and right side walls of the housing block 4 are in contact with the inner wall of the limiting side plate 8. The limiting plate 9 and the limiting side plate 8 are arranged adjacently and perpendicularly. The inner wall of the limiting side plate 8 is planar, and the inner wall of the limiting plate 9 has an arc-shaped structure. Both the limiting side plate 8 and the limiting plate 9 form a telescopic structure on the bracket 6 via the second electric telescopic rod 7. The maximum height of the housing block 4 is less than the depth of the housing body 14, and the vertical distance between the upper end face of the housing body 14 and the upper end face of the housing block 4 is equal to the thickness of the lower end face of the sealing ring body 13. (Assembly) When the housing body 14 is engaged with the housing block 4, the control switch of the button switch 2 is turned on, and the housing body 14 is pushed upward by the first electric telescopic rod 3. The upper end face of the support plate 5 contacts the lower end face of the limiting plate 16 on the lower side of the limiting hole 15. The housing body 14 passes through the limiting plate 16. At the same time, the limiting side plate 8 and the limiting front plate 9 are retracted and slid by the second electric telescopic rod 7. The inner walls of the limiting side plate 8 and the limiting front plate 9 are in contact with the outer surface of the housing body 14, which facilitates the stable clamping and fixing of the housing body 14 and avoids skewing. It is also convenient for the sealing ring body 13 to correspond vertically with the housing body 14. The mounting plate 11 is pushed downward by the third electric telescopic rod 12, which facilitates the docking and engagement of the sealing ring body 13 and the housing body 14, and facilitates stable assembly.

[0032] Combination Figure 4As shown, the anti-detachment structure 10 includes a sleeve 1001, an elastic plate 1002, and a protective plate 1003. An mounting plate 11 is fixedly connected to the upper end face of the sleeve 1001. Elastic plates 1002 are provided on both the left and right side walls of the sleeve 1001. The protective plate 1003 is integrally connected to the lower end face of the elastic plate 1002. The elastic plate 1002 is inclined on the side wall of the sleeve 1001, and the elastic plate 1002 and the protective plate 1003 form an "L" shape structure. The elastic plate 1002 is elastically set on the sleeve 1001, which facilitates the use of the elastic tension of the elastic plate 1002 to support the inner wall of the sealing ring body 13, making it easy to install and fix it stably on the anti-detachment structure 10, preventing the sealing ring body 13 from falling off the anti-detachment structure 10, and facilitating installation and fixation.

[0033] Combination Figure 1 and Figure 4 As shown, the limiting hole 15 is opened in the middle of the limiting plate 16, and the limiting plate 16 is fixedly connected to the upper inner wall of the bracket 6. The limiting plate 16 has a "+" shaped structure. The depth dimension of the housing body 14 is equal to the height dimension of the inner wall of the limiting plate 9, and the depth dimension of the housing body 14 is equal to the height dimension of the inner wall of the limiting side plate 8. The outer wall of the housing body 14 fits against the inner walls of the limiting side plate 8 and the limiting plate 9, which facilitates stable clamping of the housing body 14. It also facilitates the sliding adjustment of the limiting side plate 8 and the limiting plate 9 by the second electric telescopic rod 7 using the cross structure of the limiting plate 16, which facilitates control of the sliding distance between the limiting side plate 8 and the limiting plate 9, so as to stably clamp the housing body 14. This is the working process of the sealing sleeve and housing assembly fixture.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
