Abstract
The utility model relates to a positioning sleeve of a needle bar and a presser foot of a sewing machine. A plurality of small through holes are uniformly arranged on the wall of the positioning sleeve, and lubricant is fulfilled inside the small through holes, and the lubricant is of graphite or a mixture of graphite and lubrication oil. The graphite is arranged inside the positioning sleeve to be used as lubricant, thereby preventing the lubricant from easily overflowing while ensuring the lubrication effect.
Description
Technical field
The utility model relates to sewing machine technique, specifically is a kind of needle bar of sewing machine positioning sleeve that does not have oil.
Background technology
During Sewing machines work, by shank move up and down and common cooperation of following presser feet and the driving cog on the workbench realizes, in order to guarantee that the work of shank and presser feet the time does not wander off, on the upper and lower of shank and presser feet, all be socketed with positioning sleeve, positioning sleeve with the high-speed friction process of shank and presser feet in, will inevitably produce wearing and tearing and heating, in order effectively to reduce wear and to generate heat, at present common way with regard to the time inject lubricating oil in the positioning sleeve the inside and reduce friction, reduce heating, but can evaporating in the course of work, lubricating oil needs the long-term fuel feeding of oil pump, and lubricating oil also can be dirty along shank, drop onto on the processing clothing, influence processes the quality and the aesthetics of product; And long positioning sleeve endoporus change of time one is big, and leakage of oil is severe more.
The utility model content
The purpose of this utility model is to provide a kind of nothing oil positioning sleeve of needle bar of sewing machine, adopts graphite as lubricant in the positioning sleeve, the worry of having avoided lubricating oil to overflow easily when guaranteeing lubricant effect.
The utility model is this realization,
The positioning sleeve of a kind of needle bar of sewing machine and presser feet is characterized in that: have several small through hole equably on the wall of positioning sleeve, small through hole is filled full lubricant.
Described lubricant is that graphite or graphite and lubricating oil mix.
The utility model is according to the graphite characteristic, adopt this kollag of graphite, and the mixture of graphite or graphite and lubricating oil is filled on the small through hole of positioning sleeve, in shank and presser feet and positioning sleeve high-speed friction process, the mixture of graphite or graphite and lubricating oil can play good lubricating oil effect, need not other apply oil, can guarantee again simultaneously not can liquid spill, can effectively solve the deficiency that present positioning sleeve exists.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the positioning sleeve of a kind of needle bar of sewing machine and presser feet has several small through hole 2 equably on the wall of positioning sleeve 1, and small through hole is filled full lubricant 3.
We can only select graphite as lubricant 3 in the selection of lubricant 3, because graphite good lubricating effect, friction in the time of can effectively guaranteeing shank and positioning sleeve high-speed friction reduces wear and generates heat, and the graphite of solid can excessively not have influence on processing work simultaneously.
In addition in order to reach better effect, we adopt the graphite apply oil to mix in the special small through hole that is filled on the positioning sleeve, the process of filling is as follows: elder generation is squeezed into small through hole with graphite and small through hole is filled up, logical more professional instrument is found time the air in the gap of graphite inside in the small through hole, and the lubricating oil that in the gap of graphite vacuum, reinjects, the mixture of this graphite and lubricating oil has better lubricant effect, and guarantees that lubricating oil is not excessive.
Claims (2)
1, the positioning sleeve of a kind of needle bar of sewing machine and presser feet is characterized in that: have several small through hole equably on the wall of positioning sleeve, small through hole is filled full lubricant.
2, the positioning sleeve of a kind of needle bar of sewing machine as claimed in claim 1 and presser feet is characterized in that: described lubricant is that graphite or graphite and lubricating oil mix.
