[0040] Embodiment 1

[0041] As shown in the figure, a fuel filter filtering detection device, including filtering detection fixture, the filtering detection fixture includes a regular hexagon structure of the regular hexagon feeding outer cylinder 23, the regular hexagon feeding outer cylinder 23 inside starts to have regular hexagonal cavity. Figures 1-7 A plurality of limiting through holes 231 for feeding and limiting the fuel filter are arranged on each outer side wall of the regular hexagon feeding outer cylinder 23. Correspondingly, a regular hexagonal cavity is arranged at the center position of the regular hexagonal cavity, and the bottom of the fuel filter is supported on the regular hexagonal inner support seat 25.

[0042]

[0043] ​The filter detection fixture further comprises an end seat 22 fixedly connected to the front and rear end positions of the regular hexahedron upper feeding outer cylinder 23, and the regular hexahedron inner supporting seat 25 is fixedly connected to the end seat 22.

[0044] During operation, the fuel filter to be detected is fed along the limiting through hole 231 and supported on the regular hexahedron inner supporting seat 25. Since the regular hexahedron upper feeding outer cylinder 23 has six side walls, multiple fuel filters can be fed on each side wall, so that one tooling can detect a certain number of fuel filters.

[0045] In order to fix the fuel filters after feeding, the filter detection fixture further comprises a plurality of cover plates 24 hingedly connected to the rear end seat 22, and the cover plates 24 are used to lock the fed fuel filters.

[0046] Specifically, six hinge interfaces 221 are formed in the rear end position end seat 22, and the rear end of the cover plate 24 is hingedly connected to the hinge interface 221 through a hinge rod 242; the front end of the cover plate 24 is locked to the front end position end seat 22 through a locking structure.

[0047] Specifically, six notches are formed in the front end position end seat 22, the front end of the cover plate 24 is integrally formed with a protruding end 243, a screw rod 2431 is fixedly connected in the notch, a through hole (the size of the through hole is larger than the size of the screw rod) is formed in the protruding end 243, and a nut is threadedly connected to the screw rod 2431.

[0048] A spring 2432 is sleeved on the screw rod 2431, one end of the spring 2432 is fixedly connected to the notch, and the other end of the spring 2432 is movably supported on the protruding end 243.

[0049] After feeding is completed, the operator flips the cover plate 24 to abut against the top position of the fuel filter, and then flips to the horizontal state, at this time, the screw rod 2431 penetrates the through hole position and presses on the spring, and then the operator locks the nut.

[0050] In the abutting and pressing state of the cover plate 24, all the fed fuel filters are locked (in actual operation, in order to buffer and protect the fuel filter, a base spring 251 for supporting and placing the filter is welded on each side wall of the regular hexahedron inner supporting seat 25, and the base spring 251 is compressed to the shortest length during the cover plate 24 cover pressing, and the filter is pressed between the cover plate 24 and the base spring).

[0051] After locking, the oil inlet and outlet pipes of the fuel filter are located between the cover plate 24 and the regular hexagonal loading outer cylinder 23 (the oil inlet and outlet pipes are located at the upper end of the fuel filter). During the test, in accordance with the existing fuel filter test method, the hose on the test equipment (test oil pump) is connected to the oil inlet pipe on the filter (not shown in the figure), and the drain pipe is connected to the oil outlet pipe on the fuel filter. After the test oil is pumped in, a row of fuel filters can be tested at one time.

[0052] During the testing process, because the filter is in a limited position, the filter will not be violently shaken by the impact of the oil when the test oil is pumped in, thus preventing the test hose from falling off.

[0053] Example 2

[0054] like Figures 1-7 As shown, this embodiment, based on the structure of embodiment 1, aims to achieve one-time material loading during the testing process and to switch to testing the filter on another side wall after testing the filter on each side wall of the hexagonal feeding cylinder 23, thereby increasing testing efficiency. Rotary shafts are fixedly connected to the aforementioned end seats 22, and these shafts are rotatably connected to shaft brackets 11. Simultaneously, the fuel filter testing device also includes a drive motor 21, the output shaft of which is fixedly mounted on the rear rotating shaft.

[0055] During operation, after feeding one side, the drive motor 21 is turned on to switch to feeding the other side. Similarly, after inspecting one side, the process is switched to inspect the other side.

[0056] Meanwhile, the aforementioned fuel filter testing device also includes an oil reservoir 1 installed at the bottom of the rotating shaft bracket 11. In the event of a filter leak during testing, the oil will fall into the oil reservoir 1 to prevent contamination.

[0057] Example 3

[0058] like Figures 1-7 As shown, in this embodiment, based on the structure of embodiment 2, the cover plate 24 is provided with a plurality of through hole structures corresponding to the positions of the limiting through holes 231; rubber baffles 241 are fixedly connected to the through hole structures respectively.

[0059] Specifically, the transverse cross-sectional shape of the rubber baffle 241 is hemispherical, and the concave surface of the rubber baffle 241 faces the limiting through hole 231.

[0060] During operation, after the cover plate 24 is closed, the rubber baffle 241 (whose shape matches the top shape of the filter) covers the top of the filter, further increasing the stability of the filter under the cover of the rubber baffle 241. When the detection oil of unstable hydraulic pressure is pumped in, the rubber baffle 241 further prevents the filter from shaking.

[0061] In actual work, according to the position of the inlet and outlet oil pipes on the filter (i.e. different types of filters), a through hole is formed in the rubber baffle 241 to pass through the inlet and outlet oil pipes, i.e. when the oil pipe of the filter is vertically connected to the top of the filter housing, a through hole is formed in the rubber baffle 241 to facilitate the penetration of the oil pipe. When the oil pipe is horizontally connected to the filter housing (at this time, the inlet and outlet oil pipes of the fuel filter are located between the cover plate 24 and the regular hexagonal outer cylinder 23), the soft tube for detecting the oil of the pump is directly connected horizontally.

[0062] Of course, the above description is not a limitation of the present application, and the present application is not limited to the above examples. Changes, modifications, additions or replacements made by those skilled in the art within the scope of the present application should also be within the scope of the present application.
