Abstract
The utility model relates to an oil pump for a sewing machine. An oil supply hole, an impeller mounting hole and a plunger hole are formed on an oil pump body; an oil supply nozzle is connected with the oil supply hole; an impeller mounting shaft is rotatably connected inside the impeller mounting hole; an oil return plunger is plugged inside the plunger hole; a plunger bolt is screwedly connected inside the plunger hole at the outer end of the oil return plunger; a plunger spring is arranged between the opposite end surfaces of the plunger bolt and the oil return plunger; an impeller supporting plate is fixed on the oil pump body; a mounting shaft hole is formed on the impeller supporting plate; the impeller mounting shaft is plugged inside the mounting shaft hole; an impeller body on an impeller is positioned inside the oil pump body on the other side of the impeller supporting plate; a filtering net is arranged inside the oil pump body; and a filtering net snap ring for fixing the filtering net is arranged on the oil pump body. When the oil pump operates, the torque force of the impeller is only 0.2 kg*cm, so as to avoid damage to the impeller of the pump body and prolong the service life of the pump body; and the oil return amount of the oil pump is up to 30 ml/min. The oil pump also has simple structure and low manufacturing cost.
Description
Technical field
The utility model relates to a kind of oil pump, especially a kind of use in sewing machine oil pump.
Background technology
At present, general use in sewing machine oil pump comprises that oil pump body, oil return plunger, impeller, fuel feeding connect mouth, plunger spring and plunger screw etc.Its structure is comparatively complicated, and manufacturing cost is higher, and fuel delivery is 30ml/min, therefore recirculating oil quantity only is 15ml/min, has the recirculating oil quantity smaller defect, but during its oil pump work impeller torsion up to 0.4kgcm, the impeller of the pump housing is damaged easily, shorten the service life of the whole pump housing.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of use in sewing machine oil pump that service life, recirculating oil quantity are bigger, simple in structure, manufacturing cost is lower that prolongs the whole pump housing is provided.
The technical scheme that provides according to the utility model, described use in sewing machine oil pump, be included in the oil-feed port of offering on the oil pump body, impeller installing hole and plunger hole, on oil-feed port, be connected with fuel feeding and connect mouth, in the impeller installing hole, be rotatably connected to the installation shaft of impeller, in plunger hole, be plugged with the oil return plunger, in the plunger hole of oil return plunger outer end, be bolted with plunger screw, between plunger screw and the opposed facing end face of oil return plunger, be provided with the plunger spring, on oil pump body, be fixed with the impeller supporting plate, offer installation axle hole on the impeller supporting plate, the installation shaft of described impeller promptly is plugged in this installation axle hole, and the impeller body on the impeller is in the oil pump body of impeller supporting plate opposite side.
Be provided with screen pack in the described oil pump body, on oil pump body, be provided with the screen pack trim ring that is used for fixing screen pack.
In the utility model when work,, impeller torsion is 0.2kgcm only, avoids the damage of the impeller of the pump housing, shortens the service life of the whole pump housing, and its recirculating oil quantity but can reach 30ml/min, and the utility model is simple in structure, manufacturing cost is lower.
Description of drawings
Fig. 1 is the utility model STRUCTURE DECOMPOSITION figure.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in Figure 1: comprise oil pump body 1, oil return plunger 2, plunger spring 3, plunger screw 4, impeller 5, impeller supporting plate 6, fixedly screen pack 7, screen pack trim ring 8, fuel feeding connect mouth 9, oil-feed port 10, impeller installing hole 11, plunger hole 12, installation shaft 13, installation axle hole 14 and impeller body 15 etc.
The utility model offers oil-feed port 10 on oil pump body 1, impeller installing hole 11 and plunger hole 12, on oil-feed port 10, be connected with fuel feeding and connect mouth 9, in impeller installing hole 11, be rotatably connected to the installation shaft 13 of impeller 5, in plunger hole 12, be plugged with oil return plunger 2, be bolted with plunger screw 4 in the plunger hole 12 of described oil return plunger 2 outer ends, between plunger screw 4 and oil return plunger 2 opposed facing end faces, be provided with plunger spring 3, on oil pump body 1, be fixed with impeller supporting plate 6, offer installation axle hole 14 on the impeller supporting plate 6, the installation shaft 13 of described impeller 5 promptly is plugged in this installation axle hole 14, impeller body 15 on the impeller 5 is in the oil pump body 1 of impeller supporting plate 6 opposite sides, in oil pump body 1, be provided with screen pack 7, on oil pump body 1, be provided with the screen pack trim ring 8 that is used for fixing screen pack 7.
During work,, continuing under the rotation by the installation shaft 13 of Sewing machines power transmission shaft transmission impeller 5, the fuel feeding task is finished in impeller body 15 rotations of impeller 5, under the effect of the groove of installation shaft 13 and plunger spring 3, force oil return plunger 2 to pump, thereby finish the oil return task of Sewing machines.
The pump oil course of work can be divided into following two stages
1, the oil return stage
When the groove part of installation shaft 13 turns round, under the effect of plunger spring 3, oil return plunger 2 moves downward, the grease chamber produces vacuum, when axle rotates 300 °, be filled in the sewing machine oil grease chamber in outside oil outlet is discharged oil pump body 1, during 360 ° of axle rotations, oil return plunger 2 is got back to previous status, and oil return finishes.
2, fuel feeding process
When the installation shaft 13 of Sewing machines power transmission shaft transmission impeller 5, impeller body 15 is continuing under the state that rotates, and finishes fuel feeding and enters each position that need lubricate of Sewing machines along oil duct, thereby finish fuel feeding.
