Detailed description of the invention
In order to know more about technology contents of the present utility model, especially exemplified by specific embodiment and coordinate above-mentioned institute accompanying drawings to be described as follows.
Tail core of the present utility model, as the key components and parts in adapter component as shown in Figure 1, the adaptor accessory shown in Fig. 1 can be different from other coordinate separately as a parts so that tail core is able to design in the structure of more products applied as independent type part.Structure and its application in adapter component as shown in Figure 1 below in conjunction with tail core illustrate that it implements.
As depicted in figs. 1 and 2, according to preferred embodiment of the present utility model, a kind of adapter component, including flange ring 1, seamless steel pipe 2 and a tail core 3, described seamless steel pipe 2 is connected between flange ring 1 and tail core 3, together with one end 2a of tail core 3 and seamless steel pipe 2 is welded and fixed by friction welding (FW), together with the other end 2b of seamless steel pipe 2 and flange ring 1 are welded and fixed by friction welding (FW), together with one end 3a of described tail core 3 and one end 2a of seamless steel pipe 2 is welded and fixed by friction welding (FW).
The adapter component of the present embodiment, when follow-up application, the body of this tail core 3 will assemble from the position of 3b a sebific duct, and be enclosed within the outside of tail core 3, and also will overlap a sleeve on tail core 3, be used for fixing sebific duct.
As Fig. 3 combines shown in Fig. 4, the through hole being internally formed two sections of connections of tail core 3, wherein, the first through hole 3-1 of one end 2a closing on described seamless steel pipe 2 has less first size φ1(through-hole diameter), the second through hole 3-2 away from described seamless steel pipe 2 one end 2a has the second bigger size φ2(through-hole diameter), wherein φ1<φ2。
As an exemplary explanation, such as Fig. 4, the first size φ in the present embodiment1Value is 13mm, first size φ2Value is 15mm.
As shown in Figure 3,4, in tail core 3, first through hole 3-1, the second through hole 3-2 are without intersecting or nest relation, first through hole 3-1, the second through hole 3-2 are connection inside tail core 3, and at link position, the angle being formed the slope 3-3 of a transition, this slope 3-3 and the second through hole 3-2 edge line by the body part of tail core 3 is 45 °.So, when oil passes through from tube core 3 inside, stop is not had.
Preferably, the junction point position such as Fig. 4, transitional slope face 3-3 and the first through hole 3-1, the second through hole 3-2 forms circular sliding slopes respectively, and arc radius is 0.5mm, and such more convenient oil by without forming stop, rounding off in junction point position.
I.e. close on one end of seamless steel pipe 2 at one end 3a of tail core 3, it is externally formed with an arc edge 3a-1, for together with one end 2a friction welding of described seamless steel pipe 2.
Such as Fig. 3, shown in 4, what the part formation one being connected with described arc edge 3a-1 was protruded withholds groove 3a-2, this is withheld groove 3-2a and is formed by a base and two sides being attached thereto, its insole binding and two side link positions i.e. withhold the interior interruption-forming circular sliding slopes of groove 3a-2, preferably, internal orifice arc radius is as 0.2mm, two sides i.e. withhold the opening formation arc-shaped of groove 3a-2 at the edge away from base, opening arc radius is 0.3mm, so, after sleeve set comes up, withhold that can to ensure that sleeve is withheld when this withholds groove 3a-2 saturated as far as possible, do not wear and tear.
As shown in Figure 5, it is preferable that described in withhold in the dual-side of groove 3a-2, form the inclination angle of one 10 ° away from the arc-shaped edges of described arc edge 3a-1, to meet the requirement that sleeve closes up so that close up to fill up and withhold groove 3a-2 saturatedly.
At the other end 3b of tail core 3, its outer front end forms pyramidal structure, and cone angle is 8-20 °.So, follow-up during this tail core 3 overlaps sebific duct, conveniently it is inserted in.In the present embodiment, as shown in Figure 4, cone angle preferably 17 °.
As shown in Figure 3,4, outside the body part of tail core 3 between described pyramidal structure and arc edge, it is externally formed with multiple being arranged side by side and pawl that direction is consistent, and the profile of tooth of pawl is towards the direction of described seamless steel pipe 2, and profile of tooth angle is 45 °.So, after sebific duct is on tube core, it is to avoid drain the oil occurs.
Described flange ring 1 include a flange ring body 1a and with this integral part of slope transitions 1b of flange ring body, the inclination angle scope of described slope transitions between 30-80 degree, preferably 62 degree, thus convenient welding with seamless steel pipe.
Flange ring body 1a, the interior bone of slope transitions 1b are of the same size with the pore of described seamless steel pipe 2.Together with the other end 2b of slope transitions 1b and seamless steel pipe 2 is welded and fixed by friction welding (FW).
Preferably, described flange ring body 1a is additionally provided with at least one cannelure, is conveniently extended application, utilize and withhold nameplate or nameplate etc., and without carrying out OEM or processing on seamless steel pipe or tube core.
Shown in Fig. 3, Fig. 4, tail core 3 described by embodiment the most of the present utility model, can be separately as parts, it is different from the adaptor shown in Fig. 1 to turn part coordinate with other, such as tail core 3, flange ring 1 and seamless steel pipe 2 are all applied as modular assembly/parts so that tail core 3 is able to design in the structure of more products applied as independent type part.
Although this utility model is disclosed above with preferred embodiment, so it is not limited to this utility model.This utility model art has usually intellectual, without departing from spirit and scope of the present utility model, when being used for a variety of modifications and variations.Therefore, protection domain of the present utility model is when being as the criterion depending on those as defined in claim.
