Further, the root of step head is provided with O shape circle.
According to another aspect of the present invention, provide the pressing method of the sliding distribution cylinder sleeve of a kind of diesel engine thin-wall, concrete steps comprise:
At first, clean engine cylinder block by normal process, make the cylinder block bottom surface down, circulate to press-fiting the cylinder jacket post by roller-way, this moment, movable rollgang descended, and cylinder block is fallen on the supporting plate of location, made the end circle of cylinder block cylinder-bore fall on the step head of this press-loading apparatus guiding head;
Then, the guiding head rises under the lifting of press-loading device, is nested into cylinder body opening stop portion, and be inserted in the step head to cylinder jacket this moment;
Afterwards, hold up under the effect in the holder of artificial pressure or press pressure and this press-loading apparatus, cylinder jacket is pressed onto in the cylinder-bore slowly;
At last, when the guide head subordinate of this press-loading apparatus dropped to minimum point, the cylinder block rollgang rose, and guiding head and cylinder jacket break away from, and finish cylinder jacket and press-fit.
According to technical scheme of the present invention; fast rise when the guiding head of this press-loading apparatus rises; slowly descend during decline; be conducive to improve productive temp and protection cylinder jacket; the guider head is round platform; make cylinder jacket import cylinder hole efficient height; press-fit process in cylinder jacket; cylinder jacket is held up down in the holder of guider head and is slowly pressed down; preventing from press-fiting the process cylinder jacket is clashed into; assurance press-fits quality, thereby avoids owing to cylinder jacket press-fits significant trouble such as bulge loop fracture and then the extraordinary wearing and tearing that cause and gas leakage lubricating oil carry-over on the improper cylinder liner deformation that causes, the cylinder sleeve.

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 subjected to the restriction of the specific embodiment.
Referring to Fig. 2 and Fig. 3, the press-loading apparatus of the sliding distribution cylinder sleeve of this diesel engine thin-wall comprises: press-loading device 1 and guiding head 2.Wherein, press-loading device 1 is hydraulic cylinder or cylinder, and has cylinder bar 11.As shown in Figure 1, guiding head 2 is column, the top has the step head 21 of truncated cone-shaped, the root of step head 21 (bottom) is provided with O shape circle, when cylinder jacket 3 is sleeved on the step head 21, the lower surface of cylinder jacket 3 is supported on the step surface 211 of this step head 21, and O shape circle is movingly tight slightly with the endoporus of cylinder jacket 3; The middle part, lower surface of guiding head 2 has upwardly extending screwed hole 22 vertically.
During assembling, press-loading device 1 vertically arranges, and guiding head 2 is installed on the cylinder bar 11 of press-loading device 1 by screwed hole 22, and locks by locking nut.When leading head 2 when rising to topmost, the step surface 211 of guiding head 2 is concordant with the following circle of cylinder-bore seam 4, and is concordant with justifying bottom of cylinder-bore 5 when guiding head 2 drops to bottom;
When press-loading device 1 is hydraulic cylinder, on the oil pipe oil circuit of hydraulic cylinder check valve and overflow valve are housed, one-way valve opens when rising, guiding head 2 fast rise as required puts to support cylinder jacket 3 in place, closed check valve when press-fiting cylinder jacket 3, overflow valve is opened, and guiding head 2 slowly descends, and at this moment cylinder jacket 3 is slowly depressed simultaneously.
