Abstract
The utility model discloses an assembling mould for a rear oil seal of an engine crankshaft. According to the technical scheme, the assembling mould is composed of two parts, namely a support sleeve and a propelling sleeve; the outer diameter of the support sleeve is varied, and the front end face of the support sleeve is a bevel with a varied inner diameter, wherein the bevel is the same as a chamfering bevel arranged at the rear end of the engine crankshaft; the support sleeve is provided with two positioning holes used for fixing the crankshaft, wherein the two positioning holes are spaced at 180 degrees; a guide sleeve is arranged at the center of the rear end of the support sleeve; the foremost end of the propelling sleeve is provided with a propelling surface, wherein a guide column is arranged at the center of the propelling sleeve, and a press-in propelling end is arranged at the center of the outer end of the propelling sleeve. Before assembly, the rear oil seal is preassembled on the support sleeve, the size of the outer diameter of the support sleeve is slightly larger than the size of a lip of the oil seal and the size of the rear end of the crankshaft, the support sleeve is opened on the condition that the lip of the oil seal is not damaged, and finally the oil seal is pressed in the engine through the press-in propelling end of the propelling sleeve. The assembling mould for the rear oil seal of the engine crankshaft has the advantages of being capable of greatly shortening working time of assembling the oil seal of the engine crankshaft and protecting surrounding parts at the same time.
Description
Technical field
The utility model belongs to the engine assembly instrument, is specifically related to a kind of mold of engine crankshaft rear oil seal assembling.
Background technology
As everyone knows, lubricating oil system is the important component part that guarantees the normal operation of engine, and in the course of the work, crankshaft rear oil seal must guarantee the seal oil of engine flywheel end to engine, is also one of topmost seal of engine.Because engine components are various, position is quite compact, while assembling such as the engine Rear oil seal, due to the complexity of the impact that is subject to space scale and operation, is easy to the lip of oil sealing is squeezed to wound, causes thus oil seal failure.If this situation finds not in time, will make engine occur the flywheel end leakage of oil gently needing to change oil sealing when operation, heavy cause the bad damage engine of engine lubrication.The generation of the problems referred to above, suffer from the instrument that is not exclusively used in the oil sealing assembling exactly, and proposition of the present utility model can make the difficult problem of this oil sealing assembling be satisfactorily resolved.
Summary of the invention
The purpose of this utility model is that a kind of Special mould of engine crankshaft rear oil seal convenient for assembly is provided.
The engine crankshaft rear oil seal assembly mould, its technical scheme is: mold is by support set and advance two parts of cover to form, the external diameter of support set is reducing, and the internal diameter of support set front end face is also that the ，Gai inclined-plane, inclined-plane of reducing is consistent with the chamfering inclined-plane of engine crankshaft rear end.Support set is provided with two locating holes for fixed crankshaft, two 180 °, locating hole intervals.Center, support set rear end is provided with guide thimble.What advance cover is pressure surface foremost, advances the cover center to be provided with lead, advances the center of cover outer end to advance end for being pressed into.
Its principle is: before assembling, oil sealing is contained on support set in advance, the outside dimension of support set is more slightly bigger than the rear end size of the lip of oil sealing and bent axle, in the situation that the oil sealing lip is destroyed, does not strut, and finally with advancing cover to be pressed into end, oil sealing is pressed into to engine.
The beneficial effect of characteristics of the present utility model and generation is, can shorten dramatically the working time of assembling oil seal for crankshaft of engine, can protect the intact of peripheral part simultaneously.
The accompanying drawing explanation
Fig. 1 is the utility model support set principle and structural profile schematic diagram.
Fig. 2 is that the utility model advances cover principle and structural profile schematic diagram.
Fig. 3 is the utility model embodiment assembly structure schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing and by specific embodiment, principle of the present utility model and structure are further described.
The engine crankshaft rear oil seal assembly mould, its structure is: mold is by support set 1 and advance 5 two parts of cover to form, the end face external diameter of support set is gradual change, and the internal diameter of support set front end face is also the inclined-plane 2 of reducing, and this inclined-plane is consistent with the chamfering inclined-plane of engine crankshaft rear end.Support set is provided with two locating holes 3 for 180 °, fixed crankshaft 10, two locating hole interval, and center, support set rear end is provided with guide thimble 4.What advance cover 5 is the pressure surface 6 of oil sealing 9 foremost, advances the cover center to be provided with lead 7, advances cover center, outer end to advance end 8 for being pressed into.The internal diameter of guide thimble is greater than lead external diameter 0.5mm.
Two locating holes of support set are that also there is bolt hole the rear end of bent axle for connecting bent axle.The inclined-plane of support set is the chamfering that coordinates crankshaft rear end, so that better fixed support cover.Because advance the internal diameter of sleeve pipe to be a bit larger tham the lead external diameter, so can guarantee support set and advance the cover cohesive position accurate.The support end of mold is the prepackage oil sealing.After first support set and crankshaft rear end is fixing, by coordinating of guide thimble and lead, oil sealing 9 is put into and advanced cover and gradually be pushed into the maximum outside diameter end from support set external diameter smallest end, and then with the propelling sleeve pipe, being pressed into the pressure surface of end can be by oil sealing parallel being pressed in engine gently.Support set and propelling cover have position limitation, can guarantee the accurate location of oil sealing.
