Abstract
Description
Technical Field
[0001] The utility model relates to a detection tool, in particular to an air filter assembly foolproof tool. Background Art
[0002] The overall structure of the air filter consists of three parts: the shell, the filter element and the top cover. The inner side of the intake pipe opening on the top cover is also equipped with a steel lining. The filter element is assembled inside the shell, and the top cover is connected to the top of the shell by screws. During the assembly process of the three, the shell is usually fixed by positioning, and then the filter element and the top cover are installed in turn, and the screws are screwed in. The whole process is assembled and inspected manually, which is prone to missing installation. Utility Model Content
[0003] In view of the above problems, the utility model aims to provide an air filter assembly fool-proof tooling, which has a novel structure and can detect each connecting screw between the top cover and the shell to prevent missing installation.
[0004] The technical solution of the utility model is an anti-fool tooling for an air filter assembly, comprising a base, on which a supporting positioning frame corresponding to the number of screws is arranged, the supporting positioning frame is supported on the lower surface of the screw connection on the outer side of the top of the shell, an inductive proximity switch for sensing the screws is arranged in the supporting positioning frame, and a display screen with an integrated control system is also arranged on the base, and a signal detected by each inductive proximity switch is displayed through the display screen.
[0005] Preferably, a diffuse reflection sensor for detecting whether the filter element inside the housing is assembled in place is also provided in the support and positioning frame.
[0006] Preferably, a steel lining detection support seat is also provided on the base, and the steel lining detection support seat is located below the air inlet pipe of the top cover, and a steel lining detection proximity switch is provided on the top of the steel lining detection support seat.
[0007] Preferably, the number of the supporting positioning frames is 7, which are arranged separately around the outer side of the shell, and the locking order of the corresponding screws along the counterclockwise direction is the first positioning frame, the sixth positioning frame, the fourth positioning frame, the second positioning frame, the seventh positioning frame, the fifth positioning frame, and the third positioning frame.
[0008] The utility model can detect each screw. If the screw is not connected in place, the inductive proximity switch will transmit the signal to the display screen for display. In addition, it can also detect whether the filter element and the steel lining are installed in place. The whole detection process is accurate and reliable, and can effectively prevent the situation of missing or not being assembled in place. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0014] like Figures 1 to 3 As shown, the utility model provides an air filter assembly foolproof tooling, including a base 1, on which a support and positioning frame 2 corresponding to the number of screws is arranged, the support and positioning frame 2 is supported on the lower surface of the screw connection outside the top of the housing, an inductive proximity switch 3 for sensing the screws is arranged in the support and positioning frame 2, and a display screen 4 with an integrated control system is also arranged on the base 1, and a signal detected by each inductive proximity switch 3 is displayed through the display screen 4. It can detect whether the screws are missing or not assembled in place.
[0015] On the basis of the above solution, a diffuse reflection sensor 5 for detecting whether the filter element inside the housing is properly assembled is also arranged in the support and positioning frame 2. It can detect whether the filter element is properly assembled.
[0016] In addition, a steel lining detection support seat 6 is also provided on the base 1, and the steel lining detection support seat 6 is located below the air intake pipe of the top cover, and a steel lining detection proximity switch 7 is provided on the top of the steel lining detection support seat 6. It can effectively detect whether the steel lining is assembled in place.
[0017] Furthermore, the number of the support and positioning frames 2 is 7, which are arranged separately around the outer side of the housing, and the locking order of the corresponding screws in the counterclockwise direction is the first positioning frame, the sixth positioning frame, the fourth positioning frame, the second positioning frame, the seventh positioning frame, the fifth positioning frame, and the third positioning frame. The 7 screws on the housing are tightened in sequence according to the above order to ensure that the filter element is sealed flat and in place, and to prevent the phenomenon that the filter element is not installed in place and causes the filtering function to fail.
[0018] When screws, filter elements, and steel linings are missing or not properly assembled, the corresponding inductive proximity switches 3, diffuse reflection sensors 5, and steel lining detection proximity switches 7 will transmit corresponding signals to the integrated control system and issue an alarm through the display screen 4, which can effectively ensure that the screws, filter elements, and steel linings are properly assembled.
[0019] The above description is only a preferred implementation mode of the utility model, and does not impose any form of limitation on the utility model. Any simple modification, equivalent change or modification made to the above embodiments based on the technical principle of the utility model still falls within the scope of the technical solution of the utility model.
