Description, but the utility model is not limited to these embodiments.
As shown in Figure 1 and Figure 2, the press-fitting tool of this crankshaft rear oil seal includes pressing sleeve 1 and for being positioned with crankshaft flange 7
Core 2, pressing sleeve 1 is sheathed on the periphery of core 2 and can slide axially, the bottom surface outer rim of core 2 have extend downwardly it is convex
Along 21, convex edge 21 leans in a ring and with the outer rim fillet surface of crankshaft flange 7.By oil seal pressing to crankshaft flange 7
During between cylinder body, the Outside Dimensions of core 2 are set with crankshaft flange 7 quite, are then positioned and fixed core 2
In the surface of crankshaft flange 7, after oil sealing is set in the periphery of core 2, be finally set with pressing sleeve 1 and pressing sleeve 1 driven to push oil
Envelope completes downwards press fitting.As shown in Figure 2 and Figure 3, the surface periphery of existing crankshaft flange 7 is through chamfered, by core
2 bottom surface outer rim sets the convex edge 21 of annular and convex edge 21 and the fillet surface on 7 surface of crankshaft flange is enable to contact against, so
After the positioning of core 2, convex edge 21 can fill the gap between core 2 at 7 surface chamfering of crankshaft flange, so as to reduce oil
The escape space after extrusion is sealed, alleviates oil sealing and is being pressed the phenomenon that generating flange in the process.For further, convex edge 21
Lateral surface extend straight down along the outer rim of core 2.Prolonged straight down along 2 edge of core by the lateral surface for setting convex edge 21
It stretches, so when the joint of core 2 and crankshaft flange 7 is almost without gap, further oil sealing of alleviating produces during press fitting
The phenomenon that raw flange.The medial surface of convex edge 21 and the outer rim fillet surface of crankshaft flange 7 fit.By setting in convex edge 21
Side and the fillet surface of crankshaft flange 7 fit, and such core 2 medial surface of convex edge 21 in assembling can determine core 2
Position carries out forced guiding, so as to improve the setting accuracy of core 2, avoids the oil sealing flange phenomenon caused by core 2 is not coaxial.
Preferably, the bottom of convex edge 21 is handled through round-corner transition.Avoid sharp portion strong by the top fillet processing for setting convex edge 21
Spend it is low cause wear-out failure, so as to extend the service life of frock.
As shown in Fig. 2, the periphery of core 2 is equipped with the guide sleeve 3 of tubular, the periphery of pressing sleeve 1 and the madial wall phase of guide sleeve 3
Fitting, the inner dimensions of pressing sleeve 1 are engaged with the physical dimension of core 2.Guide sleeve 3 is set by the periphery in core 2, and is made
Pressing sleeve 1 is inserted between guide sleeve 3 and core 2, and oil sealing can so be avoided to be squeezed during press fitting from the both sides of pressing sleeve 1
Deformation is escaped to form flange.
As shown in Fig. 2, be provided in the axial direction with through hole 22 in core 2, the inner edge of through hole 22 has the gear of annular along 23, through hole
22 are inserted with screw rod 4, and the upper end of screw rod 4 is connected with pressing sleeve 1, and the lower end of screw rod 4 is bolted with nut 5, and nut 5 is with keeping off along 23
Downside leans.By opening up through hole 22 in core 2 and setting gear along 23, the upper end of setting screw rod 4 and pressure in through hole 22
1 connection of set, lower end is connected with nut 5, and nut 5 is made to be resisted against gear along 23 downside, so can drive spiral shell when starting and be pressed
Mother 5, which tightens, drives screw rod 4 to move downward, due to screw rod 4 with pressing sleeve 1 be connected to drive together pressing sleeve 1 slowly downwards, thus
Realize press fitting operation.Preferably, nut 5 and gear are equipped with plane bearing 6 along between 23.Nut 5 and gear turn relatively along between 23
Kinetic frictional resistances are big, inconvenient, by setting plane bearing 6 along between 23 in nut 5 and gear, so substantially reduce rotation spiral shell
Resistance during mother 5, operation are more convenient laborsaving.
