Two sets of plunger pumps are composed of a main shaft, oil suction and supply shaft sleeves, plungers, etc., and the main shaft eccentricity and plungers are used for oil suction and supply. An oil piping system is composed of an oil inlet nozzle and an oil outlet nozzle, an oil line, an oil delivery pipe, an oil feeder, an oil filter, etc. The oil outlet nozzle and the oil line are utilized to carry out sufficient lubrication, the oil quantity can be adjusted, and the oil pipes are directly connected. The utility model has the advantages of simple structure, small size, large oil quantity, high oil pressure (the high speed oil pressure is in accordance with the low speed oil pressure), fast oil returning, high efficiency, and little possibility of oil seepage, and special gears are not needed.
Description
The utility model belongs to the sewing machine technique field, further relates to a kind of lubricated suction fueller of Sewing machines that is used for.
The suction fueller of existing Sewing machines adopts vane pump, gear pump etc. mostly, and oil piping system is more loaded down with trivial details, connects undesirable etc.With existing GK11-2 type tube formula crosspointer flat seaming machine is example, and its major defect has: because oil pump is installed on the food tray, because of factor affecting such as manufacturing, assembling and sealings, inevitably produced leakage of oil.Food tray connects with head, employing be movable rubber connector, very easily cause poorly sealedly, produce pressure and descend, cause oil pump oil transportation efficient to reduce, cause and inhale the fuel feeding deficiency.Oil pump is a gear pump, this pump configuration complexity, and accuracy of manufacture height, so cost is higher, pressure is too little during low-speed running in addition, has also caused suction fuel feeding deficiency.The fuel feeding deficiency makes the lubricated inadequate component wear aggravation of part, shortens machine service life, can make machine " kill " and can't use when serious.The oil suction deficiency makes the lubricating oil in the head can't normally be expelled back into oil container again, and goes down from the gap seepage of mechanisms such as shank, severe contamination sewing.
The purpose of this utility model mainly provides a kind of suction fueller simple in structure, and it makes, and oil return is unimpeded, the suction charge oil pressure increases, charge oil pressure when especially having improved low speed.
The utility model comprises main shaft, axle sleeve, plunger and oil circuit, plunger assembly itself is exactly two functions, oil suction (oil-feed) and fuel feeding (fuel-displaced), inhale fuel feeding axle sleeve or axle support holes, be loaded on the main shaft or other rotating shaft of Sewing machines, inhaling on the fuel feeding axle sleeve has several through holes, at least one oil outlet, at least one inlet nozzle, at least one plunger are housed respectively on the through hole, plunger is supported by spring and baffle plate, several eccentric breach is arranged, the position alignment plunger of eccentric breach on the machine spindle.Be associated with flexible pipe on the inlet nozzle of suction fuel feeding axle sleeve, oil filter is equipped with in the other end of flexible pipe, and the petroleum pipeline of inhaling the fuel feeding axle sleeve connects oil feeder through oily window below, goes up petroleum pipeline before oil feeder connects.The inlet nozzle of inhaling the fuel feeding axle sleeve is connected with head oil strain felt through oil return pipe, the oil outlet of suction fuel feeding axle sleeve by oil pipe to the moving parts fuel feeding.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model main shaft, axle sleeve structure schematic diagram.
Fig. 2 is the utility model oil channel structures schematic diagram.
Suction fuel feeding axle sleeve of the present utility model or axle support holes 10, it is loaded on the main shaft or other rotating shaft 1 of Sewing machines.Have 6 through holes on the suction fuel feeding axle sleeve 10, two oil outlets, two inlet nozzles, two plungers are set respectively.The through hole C that inhales fuel feeding axle sleeve 10 is connecting inlet nozzle (oil-Absorbing nozzle) 24, and inlet nozzle 24 is equipped with oil suction flexible pipe 9 and is connected with oil filter 8, and oil filter 8 is placed in the store oil of head and carries out oil strain.The B through hole of inhaling fuel feeding axle sleeve 10 is equipped with plunger 22, refills upper plug spring 20 and plunger baffle plate 16, by screw 14 plunger baffle plate 16 is fixed on and inhales on the fuel feeding axle sleeve 10.Inhale be equipped with on the A through hole of fuel feeding axle sleeve 10 the little oilhole 3 of oil outlet 18 by plastic flexible pipe and petroleum pipeline 5 upwards oil spout show that oil feeder 6 connects with preceding upward petroleum pipeline 7, the front end of petroleum pipeline 7 is drawn one section oily line and is lubricated portion mechanism before the head on preceding.Above-mentioned is that a cover is inhaled fueller.Connecting inlet nozzle (oil-Absorbing nozzle) 23 at the through hole C1 that inhales fuel feeding axle sleeve 10, inlet nozzle 23 is equipped with plastic flexible pipe 11 and head oil strain felt 12 excess oil of head front portion is all sucked back.The B1 through hole of inhaling fuel feeding axle sleeve 10 is adorning that plunger 21 refills upper plug spring 19 and plunger baffle plate 15 is fixed on plunger baffle plate 15 on the suction fuel feeding axle sleeve 10 by screw 13.Inhale on the A1 through hole of fuel feeding axle sleeve 10, oil outlet 17 is housed, constitute another set of suction fueller to the moving parts fuel feeding by plastic flexible pipe.Through hole A, A
1With B, B
1With C, C
1Angle be 65 °.
The utility model is inhaled the fuel feeding process: when main shaft 1 rotates by direction shown in Figure 1, lubricating oil is by oil filter 8, oil hose 9, inlet nozzle 24, oil is filtered the back inspiration and inhales fuel feeding axle sleeve 10, chew 18 from fuel-displaced again, oil hose and petroleum pipeline 5 oil feeders 6 and the preceding petroleum pipeline 7 of going up, aperture 3 to oily window 4 on the oil spout of lubricating oil from petroleum pipeline 5, not only can observe the size that the fuel feeding situation also shows the oil spout oil mass, upwards the oil of spray is scattered on the parts downwards from oily window 4 again, because each position parts is in motion, each parts can obtain sufficient lubrication like this, and oil feeder 6 is regulated the oil mass size of its axle and needle bar mechanism on the head front portion.
The anterior oil return process of head: inhale fuel feeding axle sleeve 10 and press in the rotary course of direction shown in the figure at main shaft 1, the oil of head front portion is connected on the oil-Absorbing nozzle 23 of inhaling fuel feeding axle sleeve 10 by head oil strain felt 12 plastic flexible pipes (oil return pipe), the rotation of machine shaft makes it produce suction, the excess oil of head front portion is directly sucked back by oil strain felt and oil return pipe, oil outlet by the A1 hole is sprayed onto oil on the parts that moved through plastic flexible pipe 2 again, has eliminated the oil leakage phenomenon of head front portion simultaneously.
This apparatus structure is very simple, and maximum characteristics are " dual-use materials ", namely utilizes suction fuel feeding axle sleeve to do bearing holder (housing, cover), utilizes main shaft to make the oil jacket core, neither reduces original properties, has increased again new function. The connection of oil circuit each several part all adopts flexible pipe directly to communicate, and does not have the first-class link of any indirect. Suction fuel feeding of the present utility model is rapid, lubricated fully, oil return is unimpeded, reduced component wear, reduced the fault generation, prolonged machine service life; The suction fuel feeding is quick, and oil leakage phenomenon is eliminated. The associated mode pipeline has reduced intermediate link, has improved oil transportation efficient and charge oil pressure, has increased oil mass; It is simple to inhale the fuel feeding axle sleeve structure, Both saved a large amount of parts, taken down former store oil dish, alleviated again machine weight, and reduced greatly cost and also simplified assembly technology.
