The specific embodiment
Below in conjunction with accompanying drawing, a specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention is not subject to the restriction of the specific embodiment.It will be appreciated that, mentioned in following embodiment of the present invention " on ", D score, " left side ", " right side ", " front " and " reverse side " all take the direction shown in each figure as benchmark, these words that are used for limiting direction are only used to be convenient to explanation, do not represent the restriction to the concrete technical scheme of the present invention.
As shown in Figure 1, the assembling device of dry liner of diesel engine of the present invention comprises: pressing machine 1, cylinder sleeve pressure head 2, cylinder sleeve fairlead 3 and little raceway assembly 4.Wherein, pressing machine 1 is cylinder jacket press-fits to provide and press-fits power.The base Shang，Qie two ends that little raceway assembly 4 is arranged on pressing machine 1 are connected with the large raceway 6 that transports cylinder block 51 to be assembled respectively, for accepting cylinder block 51 to be assembled and it being slided into the pressing machine 1 moderate position of base along raceway, prepare to press-fit cylinder jacket.
As shown in Figure 4, cylinder sleeve pressure head 2 comprises: the hemisphere top 23 at the stop lug 22He top at lower end and the adaptive plug 21 inserting of cylinder jacket 52, middle part, while press-fiting, the lower press-assembling surface of the hydraulic seat 11 of pressing machine 1 compresses hemisphere top 23 and press-fits downwards, hemisphere top 23 can allow pressure head central point vertically stressed, makes cylinder jacket 52 synchronous toward lower slider.
As shown in Figure 5 and Figure 6, cylinder sleeve fairlead 3 is tubulose, outer circumference is stepped, top small end 31 inserts with cylinder jacket 52 is adaptive, and excircle has O type ring groove, load onto after O type circle, play fine setting interference fit sleeve port, eliminate the effect in cylinder sleeve fairlead and cylinder trepanning fit tolerance gap.The large end 32 in bottom inserts with cylinder block 51Gang to be assembled hole is adaptive, forms and is accurately slidably matched.
As shown in Figure 2, little raceway assembly 4 comprises: base plate 41, raceway truss 42, roll assembly 43 and body positioning component.Wherein, base plate 41 is arranged on base 12, and raceway truss 42 is as shown in Figure 7 and Figure 8 arranged on base plate 41 by bolt, and cylinder block 51 is parallel to be supported on the rolling drum surface of little raceway assembly 4, and adjustment level, guarantees cylinder hole and the same axial line of hydraulic seat 11.As shown in Figure 9, roll assembly 43 comprises: roll shaft 431 and be located in the cylinder 432 on this roll shaft 431.Body positioning component comprises: locating piece 44(is as shown in Figure 10 and Figure 11), alignment pin 45(as shown in Figure 12 and Figure 13) and altitude location plate 46(as shown in Figure 14 and Figure 15).Cylinder block 51 advances behind pressing machine bottom along raceway, and alignment pin 45 is tightened cylinder block 51 from the side, and centering hydraulic seat 11 bottoms, location are accurately slidably matched cylinder sleeve fairlead 3 and cylinder block 51Gang hole.
As shown in figure 16, during assembling, first propulsive gas cylinder body 51 slides into the moderate position of pressing machine base 12 along raceway, cylinder sleeve fairlead 3 one end import in cylinder jacket 52 endoporus, the top in cylinder hole is placed in one end, cylinder sleeve pressure head 2 is placed on the top of cylinder jacket 52, manually pull gauge tap, Driven by Hydraulic Cylinder hydraulic seat 11 is pressing cylinder sleeve pressure head 2 down vertically, cylinder sleeve pressure head 2 promotes cylinder jacket 52 and moves in cylinder-bore, cylinder jacket 52 glides and is incorporated into the suitable position degree in cylinder hole in the guide effect of cylinder guidance cover 3, has completed the assembling of cylinder jacket.Hydraulic seat pressing cylinder sleeve pressure head down moves, the effect of cylinder sleeve pressure head 2 limited location assemblings, and while pressing to certain size, the stop lug 22 of cylinder sleeve pressure head 2 props up Gang Kong upper surface and plays restriction, thereby guarantees the accuracy of assembly technology.The dynamic pressure of next cylinder sleeve is closed, as long as unclamp, adjusts alignment pin 442, guarantees cylinder sleeve fairlead 3 same axle center, Yu Gang hole, just can assemble, the like.While dismantling cylinder sleeve if necessary, cylinder block is stood upside down and come, use special nylon block, be placed on cylinder sleeve end face, after adjustment cylinder block, nylon block is aimed at hydraulic seat, and hydraulic seat is under the effect of gauge tap, vertical extruding nylon block, cylinder sleeve down move, and cylinder sleeve is slippage immediately.Cylinder sleeve Yu Gang hole, cylinder sleeve fairlead are more accurate moving cooperation, and hydraulic seat is more loose moving cooperation with cylinder sleeve pressure head.
The assembling device of this dry liner of diesel engine is rational in infrastructure, by adopting pressing machine and raceway to transport to have improved, press-fits efficiency.In addition, adopt cylinder sleeve fairlead and positioner, effectively prevent cylinder jacket in assembling process by scratch and scored cylinder hole, guarantee assembly quality.
Disclosed is above only several specific embodiment of the present invention, and still, the present invention is not limited thereto, and the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
