Description

Linear guide rail lubrication oiling mechanism

Technical Field

The application relates to the field of sewing machines, in particular to a linear guide rail lubrication oiling mechanism.

Background

The sewing machine structure is provided with a mechanism which can realize the designated displacement work by the linear reciprocating motion of a sliding block on a guide rail. Generally, two rows of U-shaped roller bearings are mounted on the bottom surface of the slider in parallel and spaced relation, and the roller bearings may be mounted on the slider by means of a shaft screw and an eccentric threaded sleeve, or may be mounted on the slider by means of a shaft screw and a washer, and then fixed by means of a first screw and a second screw, respectively, having two axes perpendicular to each other. When the sliding block sliding table is installed on the guide rail, the two rows of roller bearings are respectively contacted with the two sides of the guide rail. When the device works, the roller bearing rolls on the guide rail to drive the sliding block to do linear reciprocating motion on the guide rail, so that the designated displacement work is completed.

Because the roller bearing of the sliding block and the guide rail are in a mutual movement relationship, a lubricating structure is arranged to ensure the normal operation of the equipment in order to avoid excessive mechanical abrasion between the components of the guide rail. In the prior art, a guide rail is lubricated by completely open grease, and the rolling part of a roller on a track is lubricated by grease.

China patent application "lubricating structure and sewing machine of sewing machine slider slip table", application (patent) no: CN201810039363.4; the lubricating structure comprises a guide rail and a slider sliding table, wherein the slider sliding table is slidably supported on the guide rail through a plurality of roller bearings, two ends of the slider sliding table are respectively provided with an oil immersion part immersed with lubricating oil, the oil immersion part is provided with a first groove with an opening facing the guide rail, and the inner circumferential surface of the first groove is in contact with the outer circumferential surface of the guide rail. Through the contact of the oil immersion part and the guide rail and the sliding of the oil immersion part along with the sliding table of the sliding block on the guide rail, lubricating oil immersed in the oil immersion part can be coated on the outer peripheral surface of the guide rail, so that the lubrication between the guide rail and the roller bearing is realized, impurities can be effectively prevented from entering a working space between the sliding table of the sliding block and the guide rail, the adhesion and winding of the impurities on the roller bearing are greatly reduced, and the working performance and the service life of the roller bearing are ensured.

The above-mentioned patent application adopts the immersion oil spare of installing on the slider slip table to realize lubricating. Lubricating oil impregnated in the oil impregnated member can be applied to the outer peripheral surface of the guide rail, thereby achieving lubrication between the guide rail and the roller bearing. But the oil on the oil immersion part is provided by the oil supply part which is made of felt or non-woven fabric. This means that the oil-immersed member cannot be lubricated once the amount of oil on the oil supply member is insufficient, and it is inconvenient to detach the pressing plate if oil needs to be replenished. If the oil supply part made of the felt or the non-woven fabric is adopted, the oil can be caused to drip through the oil immersion part if the stored oil is too much, and the pressing plate needs to be frequently disassembled by a user to supplement the oil if the stored oil is too little.
