(2), machining cutting ferrule, make that the outer wall of cutting ferrule has the first annular boss;
(3), oil pipe body is fixed by clamping, now one end of oil pipe body stretches out in the end face of clamping, the length that oil pipe body stretches out in the end face of clamping is consistent with the radial width of blocked part, and the end face of now clamping is provided with the groove matched around oil pipe body and with the shape of cutting ferrule;
(4), cutting ferrule to be nested with on oil pipe body and to make cutting ferrule be contained in the groove of clamping;
(5), by spinning machine, the part radial direction stretching out in the end face of clamping of oil pipe body is expanded formation blocked part, offset to make the end face of blocked part and cutting ferrule, and spinning machine makes the enlarged-diameter of the part of the close blocked part of oil pipe body simultaneously, with the outer wall drive fit of the inwall and oil pipe body that make cutting ferrule.
After adopting above structure and method, the present invention compared with prior art, has following advantage:
In the present invention, the inwall of cutting ferrule and the outer wall drive fit of oil pipe body, and an end face of cutting ferrule and blocked part offset, cutting ferrule is so just made to be fixed on one end of oil pipe body, and do not need to fix cutting ferrule by welding, can avoid the high temperature produced due to welding that the mechanical property of oil pipe body is reduced, also can avoid owing to welding the situation making the tube wall breakage of oil pipe.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein, 1, oil pipe body; 101, blocked part; 2, cutting ferrule; 201, the first annular boss; 3, cutting ferrule nut; 301, the second annular boss.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in more detail.
As shown in Figure 1, engine oil tube assembly of the present invention, it comprises an oil pipe body 1, one end of oil pipe body 1 is equipped with cutting ferrule 2 and a cutting ferrule nut 3, cutting ferrule 2 is fixedly connected with oil pipe body 1, cutting ferrule nut 3 is flexibly connected with oil pipe body 1, the outer wall of cutting ferrule 2 is provided with the first annular boss 201, the inwall of one end of cutting ferrule nut 3 is provided with the second annular boss 301, the end face of the first annular boss 201 offsets with the end face of the second annular boss 301 and coordinates, that is cutting ferrule nut 3 is when connecting, cutting ferrule nut 3 to be nested with on cutting ferrule 2, and the end face of the end face of the second annular boss 301 and the first annular boss 201 offsets, with by cutting ferrule nut 3 axial limiting, then cutting ferrule nut 3 screws on motor interface, with by oil pipe body 1 and motor orifice, the end face being equipped with one end of cutting ferrule 2 and cutting ferrule nut 3 of described oil pipe body 1 extends radially outwardly and forms blocked part 101, blocked part 101 is the radial ring-shaped member extended, one end face and the blocked part 101 of cutting ferrule 2 offset, the inwall of cutting ferrule 2 and the outer wall drive fit of oil pipe body 1, make cutting ferrule 2 fixedly be nested with like this to maintain static on oil pipe body 1.
The processing method of above-mentioned engine oil tube assembly comprises the following steps:
(1), by cutting ferrule nut be inserted in oil pipe body from one end of oil pipe body, when being inserted in, oil pipe body is first inserted in one end that the diameter of cutting ferrule nut is less, and namely oil pipe body is first inserted in one end being provided with the second annular boss of cutting ferrule nut;
