The oil quantity is adjustable, and the oil pipes are connected directly. The utility model has the advantages of simple structure, small size, large oil quantity, high oil pressure, fast oil returning, and high efficiency, a special suction and supply pump is not needed, and the phenomenon of oil seepage is eliminated.
Description
The utility model belongs to the stitching process field.
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 GK10-3 type three pin flat seaming machines 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 flow back to food tray 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 and oil circuit, and axle sleeve has oil suction axle sleeve and fuel feeding axle sleeve, and the oil circuit part is made up of atomizer, oil feeder, oil filter and various connecting tube.Its concrete structure is, main shaft is contained on oil suction axle sleeve and the fuel feeding axle sleeve, on oil suction axle sleeve and the fuel feeding axle sleeve housing three through holes are arranged all, through hole A and through hole C are equipped with oil outlet and inlet nozzle respectively, through hole B is equipped with plunger, plunger is supported by spring and baffle plate, two eccentric breach is arranged, the position alignment plunger of eccentric breach on main shaft.Flexible pipe one end of drawing from fuel feeding axle sleeve inlet nozzle is equipped with oil filter, flexible pipe one end of drawing from fuel feeding axle sleeve oil outlet is associated with the threeway oil nozzle, the threeway oil nozzle connects down petroleum pipeline forward, connect petroleum pipeline backward, last petroleum pipeline connects oil feeder through oily window below, go up oil pipe before oil feeder connects again, lead to oily line in this oil pipe termination.The inlet nozzle of oil suction axle sleeve is connected with the oil return pipe malthoid through oil return pipe, and the oil return pipe malthoid is positioned at the head front portion, and the oil outlet of oil suction axle sleeve links to each other with down preceding oil nozzle by oil pipe.The angle of through hole A and B and B and C is 65 °.
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.
The utility model has fuel feeding axle sleeve (11) and oil suction axle sleeve (1), the through hole A of fuel feeding axle sleeve (11) is connecting oil outlet (2), through hole C is connecting inlet nozzle (10), through hole B is adorning plunger (8) and is refilling upper plug bullet plug (7) and plunger baffle plate (6), uses screw (5) to be fixed on the fuel feeding axle sleeve (11) at last.The structure of oil suction axle sleeve (1) and fuel feeding axle sleeve (11) are basic identical, its oil outlet (3) and inlet nozzle (9) are loaded on the turnover oilhole of axle sleeve equally, when assembling main shaft (4), the eccentric breach on the axle should be aimed at the plunger (8) of inhaling the fuel feeding axle sleeve respectively.The utility model oil channel structures is, flexible pipe (23) one ends of drawing from fuel feeding axle sleeve (11) inlet nozzle (10) are equipped with oil filter (24), make the lubricating oil that enters obtain filtering, flexible pipe (21) one ends of drawing from the oil outlet (2) of fuel feeding axle sleeve (11) are connected with threeway oil nozzle (16), the threeway oil nozzle connects down petroleum pipeline (25) forward, connects petroleum pipeline (20) backward.Lubricating oil is from shunt here, and one the tunnel gives anterior down lubricating, and another road is lubricated to head top.Last petroleum pipeline (20) has a nozzle opening (18) at the position facing to loam cake oil window (19), and the oil of ejection is just reached on the oily window (19).Be connected to oil feeder (17) forward from last petroleum pipeline, be used for regulating anterior fuel delivery size.Petroleum pipeline tube connector (15) before drawing after the oil feeder, go up oil pipe (14) before being connected to, before the pipe end that oils draw one section oily line (13), this oily line (13) will be lubricated to the anterior motion of head, be connected to oil return pipe (22) from oil suction axle sleeve (1) inlet nozzle (9), oil return pipe (22) other end is with oil return pipe malthoid (12), work procephalic long-pending oil on opportunity will pass through malthoid (12) and the sucked back axle sleeve of oil return pipe (22) (1), and the following preceding oil pipe (26) that passes through oil outlet (3) connection then sprays to the support front portion to down preceding oil nozzle (27).
The utility model fuel feeding process: when main shaft (4) rotates by direction shown in Figure 1, lubricating oil is by oil filter (24), oil hose (23), inlet nozzle (10) is sucked into fuel feeding axle sleeve (11), again from oil outlet (2), fuel feed pump (21) to threeway oil nozzle (16) along separate routes, one the road to petroleum pipeline (25) ejection down, portion mechanism is lubricated before giving down, another road upwards is sprayed onto on the oily window (19) from oilhole (18) earlier through last petroleum pipeline (20), not only can observe the fuel feeding situation, lubricating oil is fallen equably carried out on each parts in the head lubricating fully, remaining lubricating oil to the preceding petroleum pipeline (14) of going up, is lubricated for last axle and needle bar mechanism by oilhole and oily line (13) through oil feeder (17).So just finished the lubricated of each main position.Oil return process: the suction that oil return axle sleeve (1) is produced under the continuous rotation of main shaft (4), the lubricating oil of being finished using in the head front portion directly sucks back by oil return pipe malthoid (12) and oil return pipe (22), oil nozzle (27) sprays to the support front portion before reaching down through down preceding oil pipe (26) then, lubricate for portion mechanism before the support, eliminated the oil leakage phenomenon of head 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. So the utility model has the advantages that very significantly, be mainly manifested in: it is very rapid to inhale fuel feeding, lubricated fully, oil return is unimpeded, reduced component wear, reduced the fault generation, prolonged machine service life; The change of oil pump position and oil return are 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; Oil jacket is simple in structure, has both saved a large amount of parts, has reduced cost and also simplified assembly technology.
