Description
Technical field
The utility model relates to Sewing machines accessory technical field, is specifically the lubrication system of the outer shuttle of a kind of sewing-machine rotating shuttle.
Background technology
Sewing-machine rotating shuttle is one of them parts of Sewing machines, and it comprises interior shuttle, outer shuttle, interior shuttle pressing plate and wire guide plate.Wherein, interior shuttle is fixed on the base plate of casing by positioning handle, and outer shuttle makes high speed rotary motion under the drive of lower shaft, therefore, has lubrication system between Nei Suo and outer shuttle.The lubrication system of the outer shuttle of sewing-machine rotating shuttle of prior art; as shown in Figure 1; usually the thin-walled of shuttle 05 is provided with oilhole 02 outside; communicate with the inner side raceway groove 06 of outer shuttle 05 thin-walled on the one hand at the bottom of the hole of this oilhole 02; communicate with the axis hole of outer shuttle 05 on the other hand; and in oilhole 02, usually can place a wool malthoid 04; cover in the outer shuttle 05 thin-walled lateral ends metal oil capping 03 of oilhole 02, to prevent the lubricating oil in oilhole 02 from the outside going to outer shuttle 05 again.
But there is following shortcoming in the outer shuttle of above-mentioned this structure: because sewing-machine rotating shuttle accessory is a parts that volume is little, complex structure, precision are high, it requires that the machining accuracy of each part is very high, and especially the requirement of surface smoothness is stricter.Usually the surfaces externally and internally of outer shuttle all needs milled processed, and metal oil capping is that shuttle will be assembled on the oilhole of outer shuttle by the punching press of punch press before grinding outside, and wool malthoid will put into oilhole in advance simultaneously.This is because punch press is when carrying out punching press to metal oil capping, need the impetus relying on outer shuttle itself as punching press, but, externally will certainly cause breakage or distortion by shuttle like this, thus cause scrapping of part.But, wool malthoid and metallic oil sealing are mounted cover when carrying out outer shuttle surface grinding after preparing, especially when on external shuttle inwall, raceway groove grinds, the impurity such as the iron end that grinding produces and abrasive pastes can from entering oilhole, thus not out, like this, one side can have a strong impact on the use of outer shuttle to be adsorbed on row on wool malthoid, also greatly reduce lubricity on the other hand, shorten the service life of product.
In prior art: 01, wire guide plate; 02, oilhole; 03, metal oil capping; 04, wool malthoid; 05, outer shuttle; 06, inner side raceway groove;
The utility model: 1, wire guide plate; 2, oil seal cover; 3, counterbore; 4, oilhole; 5, wool malthoid; 6, raceway groove in annular; 7, outer shuttle; 8, groove.
Utility model content
Technical problem to be solved in the utility model is, provide a kind of processing and assembling simple, avoid the impurity such as iron end and abrasive pastes to enter oilhole, thus ensure lubricity and the lubrication system of shuttle outside the sewing-machine rotating shuttle improving product service life.
For solving the problems of the technologies described above, the lubrication system of the outer shuttle of the sewing-machine rotating shuttle that the utility model provides, comprise wire guide plate, outer shuttle and wool malthoid, the sidewall of described outer shuttle is provided with radial oilhole, the madial wall of outer shuttle is provided with raceway groove in the circumferential annular be communicated with oilhole, wool malthoid is embedded in oilhole, and the sidewall of wire guide plate and outer shuttle is close to; It also comprises the oil seal cover that nonmetallic materials are made, described oil seal cover extrusion and rabbet at oilhole near outer shuttle wall outer surface one end place, and is compressed by wire guide plate.
The oil seal cover that described nonmetallic materials are made is rubber oil capping, and its outside dimension is greater than the aperture size of oilhole.
Described oil seal cover has towards one end of wool malthoid the counterbore concaved, and one end of wool malthoid is connected in counterbore.
One end that described lubricious oilhole is positioned at outer shuttle side-wall outer side is provided with the groove for rabbeting oil seal cover, and the cell wall of this groove is the cell wall tilted, and the notch diameter dimension of groove is less than groover rot diameter size.
After adopting above structure, the utility model compared with prior art, has the following advantages:
1) oil seal cover made due to nonmetallic materials has elasticity, it can extrusion in a groove, therefore, when processing and assemble the outer shuttle of sewing-machine rotating shuttle, individually can process outer shuttle and each oil duct and hole accordingly, and carry out independent grinding, and when assembly lube capping, only oil seal cover need be pressed into oilhole place and be compressed by wire guide plate, just can play the effect of sealing; Therefore, easy to process, outer shuttle can not be destroyed or outer shuttle is out of shape; Also make assembling more simple in addition, enhance productivity; In addition, due to part grind separately after assemble again, the iron end produced when avoiding grinding occurs enters oilhole and is adsorbed on wool malthoid, thus ensures the normal use of outer shuttle, also extends the service life of product;
2) counterbore be provided with inside oil seal cover, makes wool malthoid more stably rabbet not occur in lubricious oilhole the phenomenon offset, make sealing and lubricant effect better;
3) groove of oilhole port, its cell wall is designed to the structure tilted, and makes nonmetallic oil seal cover be squeezed better and to fill in groove on the one hand, also serves spacing effect on the other hand, makes oil seal cover be not easy to drop out from groove.
