The filter element structure generally comprises a cylindrical body, wherein two ends of the body are respectively provided with an end cover plate, and an oil pumping joint is further arranged on one end cover plate and communicated with the interior of the body. Secondly, the surface of the body is provided with a plurality of filter holes and a filter screen, and the oil pumping joint is connected with an oil pipe for oil to flow. When the oil pressure equipment is actuated, the oil in the oil pipe oil tank can enter the body through the plurality of filter holes and the filter screen and then flows out of the oil pipe connected with the oil pumping joint.
The oil pumping joint and the end cover plate are both made of metal, and the combination mode of the oil pumping joint and the end cover plate comprises adhesive combination and compression joint combination. In which the adhesive bonding easily results in poor bonding, and the adhesive used for bonding metal generally does not have good environmental characteristics. Although the most common method of crimping is crimping, in order to make the crimping process easier, a metal material with lower hardness is usually selected to make the oil well joint. The processing method is that after one end of the oil pumping joint passes through the end cover plate, one end of the oil pumping joint is extruded and deformed by a proper jig and an extruding machine and is tightly attached to the surface of the end cover plate.
Because the hardness of the material of the oil pumping joint is low, and the oil pumping joint and the end cover plate are not in surface-to-surface contact without any clamping or combination, the deformed part of the oil pumping joint is not tightly attached to the end cover plate to form a loose state, once the oil pumping joint and the end cover plate are in the loose state, the filter element is unusable and needs to be scrapped completely, so that the production cost is wasted.

Wherein the oil pumping joint (20) is provided with a threaded lock hole (22) in the axial direction, and the threaded lock hole (22) is communicated with the inside of the body (12).
Referring to fig. 2, the end cover plate (14) has a first surface (140) and a second surface (142), and the first surface (140) is opposite to the second surface (142). The end cover plate (14) has a through hole (144) and penetrates through the first surface (140) and the second surface (142), and a plurality of embedding holes (146) penetrate through the first surface (140) and the second surface (142) of the end cover plate (14) and are adjacent to the through hole (144).
The oil pumping joint (20) comprises a head part (24) connected with a neck part (26), the outer diameter of the head part (24) is larger than that of the neck part (26), the threaded locking hole (22) is positioned in the axial inner parts of the head part (24) and the neck part (26), and two ends of the threaded locking hole (22) penetrate through the head part (24) and the neck part (26), so that the threaded locking hole (22) forms a through structure.

Subsequently, the neck portion (26) is pressed by a suitable jig (30) and tool (32) to deform a portion thereof and expand the portion, which is deformed, of the neck portion (26) to form an abutment portion (28). In the process of forming the abutting portion (28), the abutting portion (28) gradually abuts against the second surface (142) of the end cover plate (14), the abutting portion (28) and the second surface (142) of the end cover plate (14) are in a close abutting state, in addition, the outer diameter of the abutting portion (28) is larger than that of the neck portion (26), and the outer diameter of the abutting portion (28) is larger than that of the structure surrounded by the plurality of embedding holes (146).
Furthermore, because the metal hardness of the material body of the oil pumping joint (20) is small, after the abutting part (28) is extruded by the tool (32), the part of the abutting part (28) corresponding to each embedding hole (146) can form the embedding hole (146) corresponding to the convex embedding salient point (29) due to the deformation and the flowing of the material. In other words, in the process of press-bonding the abutting portion (28) and the end cover plate (14), the end cover plate (14) has the structure form of the embedding hole (146), so that the abutting portion (28) automatically forms the embedding convex points (29), and each embedding convex point (29) is correspondingly embedded into the embedding hole (146).
Referring to fig. 5, according to the above description, the method for assembling the fuel tank filter element structure disclosed in the present embodiment may include an inserting step (40), a pressing step (42), an attaching step (44), and a locking step (46).
Referring to fig. 3 and 5, in the step (40), the pumping sub (20) and the end cover plate (14) are placed on the jig (30). Wherein the neck (26) with a smaller outer diameter at one end of the oil well connector (20) passes through the through hole (144) of the end cover plate (14) so that the end cover plate (14) is abutted against the oil well connector (20).
Referring to fig. 4 and 5, in the compressing step (42), the implement (32) compresses one end of the neck (26) to expand and deform the neck (26), and the deformed neck (26) is close to the end cover plate (14).
Further, the fitting step (44) is to fit the deformed neck portion (26) to the surface of the end cover plate (14).
The clamping step (46) is to enable the neck (26) which is attached to the surface of the end cover plate (14) to form a plurality of embedding convex points (29) along with the pressing of the machine tool (32) so as to extend into the embedding holes (146) of a plurality of penetrating structures of the end cover plate (14), and the end cover plate (14) and the oil pumping joint (20) form a clamping and combining state through the combination of the embedding convex points (29) and the embedding holes (146).
Therefore, the combination of the oil pumping joint (20) and the end cover plate (14) comprises a combination form of a plurality of embedding convex points (29) embedded into a plurality of embedding holes (146) in addition to a combination form of tightly leaning the leaning part (28) and the second surface (142) of the end cover plate (14), so that the oil pumping joint (20) and the end cover plate (14) can have a firmer combination effect in the embodiment.
The above are the preferred embodiments and design drawings of the present invention, which are merely illustrative and not intended to limit the scope of the present invention, which is defined by the appended claims and their equivalents, without departing from the scope of the present invention.
