Abstract
The utility model discloses an oil seal guiding device with magnetic attraction and positioning pins, which comprises a flat positioning pin(1), a round positioning pin(4), a guide sleeve(5), a handgrip(6) and magnets(8); wherein the diameter of a columnar guide circle of an outer circle at the big end of the guide sleeve(5) is equal to the diameter of a crankshaft oil seal installation circle; an inner chamfer is processed at the orifice of a flat-bottom inner round hole in the big end of the guide sleeve(5); the flat positioning pin(1), the round positioning pin(4) and more than one magnet(8)are arranged at the underside of the guide sleeve(5); the inner chamfer and the front head faces of the magnets are aligned with the back head face of the crankshaft; and the handgrip(6)is installed in a flat-bottom inner round hole in the small end of the guide sleeve(5). Under the positioning of the flat positioning pin(1) and the round positioning pin(4) and the force of the magnets, the oil seal guiding device is steadily attracted and stuck on the back head face of the crankshaft; in this way, a back oil seal of the crankshaft of an engine can be successfully assembled onto the crankshaft. The oil seal guiding device effectively solves the problem that the inner lip of the oil seal can not restore after excessive expansion, which leads to the fault of oil leakage due to poor sealing between the oil seal and the crankshaft.
Description
Technical field
The utility model relates to a kind of gatherer, relates in particular to a kind of by magnet absorption and alignment pin is reliably located, effectively prevent the oil sealing gatherer that oil seal lip excessively swells.
Background technology
In the engine manufacturing, the crankshaft rear end on the engine needs to seal with oil sealing, to prevent that lubricating oil is from engine rear end seepage.The material that is used for making oil sealing is not quite similar, with getting increasing a kind of oil sealing, its parcel property, wearability, sealing all increase, but it is restorative relatively poor after its inner lip swells that a problem is arranged, in assembling and use, do not allow excessively to swell, under the encapsulated prerequisite that satisfies with bent axle, it is the smaller the better that the oil sealing inner lip expands.Because original oil sealing gatherer directly encases the crankshaft oil seal component location guide and positions, between the oil sealing guiding circle of old gatherer and the crankshaft oil seal component location guide certain thickness is arranged all the time, and this thickness is processed difficult control, when particularly making of nonmetallic materials, thickness and circularity all are difficult to satisfy matching requirements, can't reset after causing oil seal lip excessively to swell, because of the problem of the not tight leakage of oil of oil sealing sealing is on the rise.In the case, press for a kind of magnetic alignment pin formula oil sealing gatherer that can satisfy matching requirements of design.
Summary of the invention
The purpose of this utility model be to provide a kind of can overcome prior art circumscribed, reliably adsorb the location by alignment pin and magnet, the guiding circular diameter is suitable, can prevent effectively that the oil sealing that the oil sealing inner lip excessively swells from importing assembling device.
Technical solution of the present utility model, comprise parts such as importing cover, location round pin, location cotter pilotage, magnet, handle, it is characterized in that importing cover and hold the circular hole bottom surface greatly level with both hands at the end in location round pin, location cotter pilotage and magnet are housed, handle is equipped with in the flat interior centre position, circular hole bottom surface of small end that imports cover.
Importing cover adopts nylon material to make, import the big end of cover cylindrical the cylindrical guiding circle that is equal to diameter with crankshaft oil seal installation circle is arranged, importing the big end of cover the inside is flat interior circular hole, the alignment pin and the magnet installing hole that connect before and after interior circular hole bottom surface is processed with, interior circular orifices place is processed with the interior chamfering that matches with outer chamfer shape on the crankshaft rear end face, importing cover small end cylindrical is taper guiding circle, and the inside is flat interior circular hole, the handle installing hole that connects before and after interior circular hole bottom center position has.
Magnet quantity has more than two, and end is spliced in importing cover, and the front end that has magnetic overlaps big end towards importing, plane of the common composition of the front end face of each magnet.
One end of location round pin and location cotter pilotage is spliced in importing cover, and the diameter of the other end and crankshaft rear end face screw thread path adapt, and protrudes outside the big end that imports cover, and location cotter pilotage flat horizontal surface is perpendicular to the line of centres of two alignment pin installing holes.
Handle adopts nylon material to make, and is hollow shoulder hole structure, is installed in the interior circular hole bottom surface that imports the cover small end by bolt and nut.
Owing to adopt above-mentioned technical scheme, the utlity model has following beneficial effect:
1, simple in structure, easy to operate, versatility is good;
2, accurate positioning, reliable;
3, cost of manufacture is cheap.

The specific embodiment
As Fig. 1-shown in Figure 4, the utility model magnetic alignment pin formula oil sealing gatherer, mainly comprise location cotter pilotage (1), location round pin (4), import cover (5), handle (6), magnet parts such as (8), wherein importing cover (5), to hold cylindrical greatly be cylindrical guiding circle (13), the inside has holds end circular hole (12) greatly level with both hands, the alignment pin installing hole (9) and the magnet installing hole (11) that connect before and after circular hole (12) bottom surface is processed with, there is interior chamfering (10) at the place, aperture of circular hole (12), importing cover (5) small end cylindrical is taper guiding circle (14), the inside is the flat circular hole of small end (15), the handle installing hole (16) that connects before and after circular hole (15) bottom center position has; Handle (6) is installed in the bottom surface of the flat circular hole of small end (15) that imports cover (5) with bolt (7) and nut (3); Magnet (8) end is spliced in importing cover (5), and the front end that has magnetic is towards importing the big end of cover (5), and the front end face of each magnet is formed group of magnets front end face (2) jointly; Location cotter pilotage (1), location round pin (4) one ends are spliced in importing cover (5), and the other end protrudes the outer certain-length of the big end that imports cover (5), and the flat horizontal surface of location cotter pilotage (1) is perpendicular to the line of centres of two alignment pin installing holes (9).During use, catch handle (6) with hand, to locate cotter pilotage (1), location round pin (4) aligning crankshaft rear end face two screws insertion location wherein, until group of magnets front end face (2), interior chamfering (10) develop the crankshaft rear end face and outside chamfering, under magneticaction, the oil sealing gatherer is inhaled surely on the crankshaft rear end face, like this, the bent axle Rear oil seal just can successfully be assembled on the bent axle by importing the guiding of the taper guiding circle (14) of cover (5), cylindrical guiding circle (13).Be equal to crankshaft oil seal installation diameter of a circle owing to import the diameter of the cylindrical guiding circle (13) of cover (5), after the oil sealing assembling, it is big that the degree that its inner lip swells just is unlikely to than the oil sealing on the bent axle diameter of a circle to be installed, solved effectively because the oil sealing inner lip does not reset after excessively swelling, caused bad and fault generation leakage of oil with the bent axle environmental sealing.
Fig. 5-shown in Figure 6 is the another kind of version of the utility model magnetic alignment pin formula oil sealing gatherer, promptly locatees the built-up crankshaft Rear oil seal by location cotter pilotage (1) and locating hole (17) with the alignment pin and the corresponding screw of crankshaft rear end face.
