Description

Technical Field

[0001] This utility model relates to the field of oil rail detection, and in particular to an oil rail continuity detection mechanism. Background Technology

[0002] During the production of fuel rails, after sub-parts (such as injector housings) are assembled and brazed, the fuel lines need to be tested for continuity to ensure that each line is unobstructed and to guarantee the quality of subsequent assembly. The original testing method involved workers sensing the airflow at each outlet after the air intake was input to check for blockages. This method is inefficient, and human perception is subjective and lacks objectivity. In particular, it cannot quantify the airflow volume; there are no specific test values.

[0003] Therefore, there is an urgent need for an oil circuit continuity detection mechanism that can achieve fast, accurate, and consistent results to meet the demands of efficient and high-quality production. Utility Model Content

[0004] The purpose of this utility model is to provide an oil rail continuity detection mechanism, which mainly solves the technical problems of low efficiency and subjective detection results of the existing detection method based on human perception. It has the advantages of being able to quickly, accurately and simultaneously detect whether multiple oil circuits of the oil rail under test are unobstructed, thereby improving detection efficiency and product qualification rate.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A hydraulic rail continuity detection mechanism is characterized in that: it includes a base, a positioning block installed on the base for supporting the hydraulic rail, an anti-misalignment block set at one end of the base, and a quick clamp support set on the base; a quick clamp is installed on the quick clamp support, and a plurality of air outlet connectors are also installed on the base, each air outlet connector is equipped with an air inlet plug, and each air outlet connector is connected to a float flow meter through a pipeline.

[0007] The oil rail continuity detection mechanism is characterized in that: the number and position of the air inlet plug and the air outlet connector correspond to the number and position of the oil circuit interfaces on the oil rail.

[0008] The oil rail continuity detection mechanism is characterized in that: the air inlet plug is provided with a sealing ring, which is made of oil-resistant rubber or silicone material to prevent leakage and affect the accuracy of the test.

[0009] The oil rail continuity detection mechanism is characterized in that: the quick clamp adopts a lever structure, which is used for quick pressing and releasing, and the operation time is less than one second.

[0010] The oil rail continuity detection mechanism is characterized in that it is further provided with a float flow meter mounting bracket for accommodating and installing a number of float flow meters.

[0011] In view of the above technical features, the present invention has the following beneficial effects:

[0012] 1. Compared with detection methods based on human perception, the device of this utility model has higher detection efficiency and more objective detection results.

[0013] 2. In this utility model, the positioning block, quick clamp support and quick clamp can realize the quick clamping and positioning of the oil rail to be tested.

[0014] 3. In this utility model, a sealing ring is provided on the air intake plug. The sealing ring can further seal the fuel injector seat along with the air intake plug to avoid air leakage during the testing process, which would cause inaccurate test results.

[0015] 4. In this utility model, the operator only needs to press once to complete the inspection of all oil circuits, reducing labor intensity and operation difficulty.

[0016] 5. This utility model has a simple structure and low maintenance cost, making it easy to promote and use in production lines. Attached Figure Description

As shown in the figure: it includes a base 8, a positioning block 5 mounted on the base 8 to support the oil rail 9, an anti-misalignment block 4 set on one end of the base 8, and a quick clamp support 6 set on the base 8; a quick clamp 7 is installed on the quick clamp support 6, and several air outlet connectors 3 are also installed on the base 8. Each air outlet connector 3 is equipped with an air inlet plug 2, and each air outlet connector 3 is connected to a float flow meter 11 through a pipeline.

[0022] In use, this invention first places the fuel rail 9 on the positioning block 5, ensuring that the injector seats on the fuel rail 9 are aligned with each air intake plug 2. Then, the quick clamp 7 is pressed down, ensuring that the fuel rail 9 is clamped and positioned under the combined action of the positioning block 5 and the quick clamp 7. Simultaneously, the air intake plugs 2 are further pressed into the injector seats to ensure a seal. During testing, test gas is introduced through the air inlet 1 of the fuel rail 9, and the testing status of each float flowmeter 11 is observed.

[0023] In this utility model, the function of the anti-misalignment block 4 is to prevent the oil rail 9 to be tested from being placed backwards or to prevent the placement of unsuitable oil rail products of different specifications.

Figure 3 As shown, multiple buoy flow meters 11 can be installed together on the buoy flow meter mounting bracket 12. Each buoy flow meter 11 is placed vertically and parallel, and the buoy display surface faces the same direction, which is convenient for observation.
