Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar the content disclosed by this description can understand other advantages of the present utility model and effect easily.
Refer to Fig. 1 to Fig. 4.Notice, structure, ratio, size etc. that this description institute accompanying drawings illustrates, content all only in order to coordinate description to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, still all should drop on technology contents that the utility model discloses and obtain in the scope that can contain.The upside observing paper during Fig. 2 in following examples is upper direction, and the downside of paper is lower direction, and the left side of paper is left direction, and the right side of paper is right direction, to be front to, paper direction be inwards in paper outside direction rear to.
In view of the pressure foot lifting axle of the Sewing machines of prior art or because lack lubrication and cause lift shaft serious wear at work, and produce larger noise in the course of the work; Oily measure is taken to pressure foot lifting axle, but, the oily iron filings corrosion head of sewing machine causing again wearing and tearing, and oily mechanism also makes the casting die sinking of casing complicated.Inventor of the present utility model designs a kind of lubricating oil sealing structure of pressure foot lifting axle, by configuring special oil box for pressure foot lifting axle, and oil sealing is configured between oil box and pressure foot lifting axle, pressure foot lifting axle can be lubricated in the course of the work for a long time reliably, thus light abrasion, noise are little, and make the lubricating oil of pressure foot lifting axle be reliably sealed in oil box, make lubricating oil in oil box can only in oil box and axle sleeve inner loop, thus avoid grease to exosmose carrying the iron filings corrosion head produced in wear process.
Be described in detail by the lubricating oil sealing structure of specific embodiment to pressure foot lifting axle of the present utility model below.
As shown in Figure 1 and Figure 2, a kind of lubricating oil sealing structure of pressure foot lifting axle, comprise the oil box 2 being located at sewing machine case 1 front end, the upper end of described oil box 2 is provided with tank filler sleeve, the lower end of described oil box 2 is provided with outage, plug 3 is installed in described tank filler sleeve, plug 4 is installed in described outage, between described plug 4 and outage, be also provided with seal washer (not shown).
As shown in Figure 2 and Figure 3, described pressure foot lifting axle 5 passes left surface 2a and the right flank 2b of described oil box 2, the left surface 2a of described oil box is provided with the axle sleeve 6 supporting described pressure foot lifting axle 5, and the right flank 2b of described oil box is also provided with the axle sleeve 6 supporting described pressure foot lifting axle 5.The endoporus of described axle sleeve 6 is two stage steps hole, wherein, the hole that in two stage steps hole, diameter is less directly coordinates with pressure foot lifting axle 5, play the effect supporting described pressure foot lifting axle 5, oil sealing 7 is provided with in the hole (i.e. cannelure 6a) that in two stage steps hole, diameter is larger, the endoporus of oil sealing 7 coordinates with described pressure foot lifting axle 5, by the seal oil in oil box 2 in oil box 2, avoids the grease in oil box 2 to exosmose.
As shown in Figure 4, before the presser feet lifting of installing on pressure foot lifting axle 5, crank 10, eccentric ratio regulate crank 11 to rub with described oil sealing in motion process, and cause the wearing and tearing of oil sealing, the depth H of cannelure 6a should be greater than the width W of oil sealing 7.
When pressure foot lifting axle 5 operates, the lubricating oil in oil box 2 of the present utility model plays lubrication to pressure foot lifting axle 5, makes the light abrasion of pressure foot lifting axle 5, running noise little.Along with the long-time use of pressure foot lifting axle 5, the trace wearing and tearing of pressure foot lifting axle 5 still can cause the pollution of the lubricating oil in oil box 2, at this moment, the plug 4 at the outage place of oil box 2 can be opened, contaminated lubricating oil be drained, then the plug 4 at outage place is blocked, the plug 3 at tank filler sleeve place is opened, complete the supply of new lubricating oil, then the plug 3 at tank filler sleeve place is blocked, thus realize the replacing of lubricating oil.The utility model makes the lubricating oil of pressure foot lifting axle be reliably sealed in oil box, makes lubricating oil in oil box can only in oil box and axle sleeve inner loop, thus avoids grease to exosmose carrying the iron filings corrosion head produced in wear process.
Described oil box 2 of the present utility model can be designed as integral structure with sewing machine case 1, at this moment, contour forming is gone out for the ease of mould, the front end of described oil box 2 should be provided with opening, then the front end of described opening is fixed with a cover plate 8 by securing member, be provided with sealing gasket 9 between described cover plate 8 and described opening, by the setting of cover plate 8 and sealing gasket 9, lubricating oil be sealed in oil box.
Described oil box 2 of the present utility model also can be designed as split-type structural with sewing machine case 1, then described oil box 2 is after manufacture is shaped, and is fixedly connected with sewing machine case 1 by securing member.
In sum, the setting of the oil box of the lubricating oil sealing structure of pressure foot lifting axle of the present utility model, the rear lubricating oil that enables once to refuel lubricates pressure foot lifting axle and axle sleeve for a long time, thus makes the lubrication between pressure foot lifting axle and axle sleeve abundant, and light abrasion, noise are little; The setting of oil sealing makes the lubricating oil of pressure foot lifting axle be reliably sealed in oil box, makes lubricating oil in oil box can only in oil box and axle sleeve inner loop, avoids grease and to exosmose the iron filings corrosion head carrying and produce in wear process.So the utility model effectively overcomes various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all without prejudice under spirit of the present utility model and category, can modify above-described embodiment or changes.Therefore, such as have in art and usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that the utility model discloses, must be contained by claim of the present utility model.
