Description
Technical field
The present invention relates to engine art, frock and method are held up in the auxiliary holder that particularly the sliding distribution cylinder sleeve of a kind of diesel engine thin-wall press-fits.
Background technology
Modern diesel engine carries power and easy to maintenance to expand cylinder, and cylinder jacket adopts the sliding distribution cylinder sleeve of thin-walled more and more general.
But press-fiting of the sliding distribution cylinder sleeve of thin-walled, generally adopt at present and directly press-fit or assemble by frock by hand, guide fence is not carried out to thin-walled sliding distribution cylinder sleeve during owing to press-fiting, make the sliding distribution cylinder sleeve of thin-walled and cylinder-bore centering difficulty, and easy scored cylinder cover, even cause cylinder liner deformation, more seriously press-fit process thin-walled sliding distribution cylinder sleeve top bulge loop easily and cylinder-bore seam clash into and easily cause cylinder sleeve top bulge loop band to rupture, then affect the contact between cylinder sleeve and piston ring and sealing, occur the significant trouble such as extraordinary wearing and tearing and gas leakage lubricating oil carry-over.
Summary of the invention
The technical problem that the present invention solves is to provide and a kind ofly can improves the auxiliary holder that the sliding distribution cylinder sleeve of diesel engine thin-wall press-fits and hold up frock and method.
For achieving the above object, according to an aspect of the present invention, provide the auxiliary holder that the sliding distribution cylinder sleeve of a kind of diesel engine thin-wall press-fits and hold up frock, comprising: press-loading device and guiding head; Press-loading device is hydraulic cylinder or cylinder; Guiding head is column, and top has the truncated cone-shaped step head with cylinder jacket adaptation, and bottom is screwed on the cylinder bar of press-loading device.
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:
First, by normal process cleaning engine cylinder block, cylinder block bottom surface is made down, circulate to press-fiting cylinder jacket post by roller-way, now movable rollgang declines, and cylinder block is fallen on the supporting plate of location, makes the end of cylinder block cylinder-bore circle fall on the step head of this press-loading apparatus guiding head;
Then, the rising under the lifting of press-loading device of guiding head, is nested into cylinder body opening stop portion, now cylinder jacket is inserted in step head;
Afterwards, under artificial pressure or press pressure hold up effect with the holder of this press-loading apparatus, cylinder jacket is pressed onto in cylinder-bore slowly;
Finally, when the guide head subordinate of this press-loading apparatus drops to minimum point, cylinder block rollgang rises, and guiding head and cylinder jacket depart from, and complete cylinder jacket and press-fit.
According to technical scheme of the present invention, the guiding head of this press-loading apparatus rises when rising fast, slowly decline during decline, be conducive to improving productive temp and protection cylinder jacket, guider head is round platform, cylinder jacket is made to import cylinder holes efficiency high, process is press-fited in cylinder jacket, cylinder jacket slowly presses down under the holder of guider head is held up, prevent from press-fiting Process Gas cylinder sleeve to be clashed into, guarantee press-fits quality, thus avoid because cylinder jacket press-fits improper and cylinder liner deformation that is that cause, bulge loop fracture and then the significant trouble such as the extraordinary wearing and tearing caused and gas leakage lubricating oil carry-over on cylinder sleeve.

Detailed description of the invention
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 not by the restriction of detailed description of the invention.
See Fig. 2 and Fig. 3, the auxiliary holder that the sliding distribution cylinder sleeve of this diesel engine thin-wall press-fits holds up frock to comprise: 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, top has the step head 21 of truncated cone-shaped, the root (bottom) of step head 21 is provided with O shape circle, when cylinder jacket 3 is sleeved on 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 and the endoporus of cylinder jacket 3 are slightly tight dynamicly to coordinate; In the middle part of the lower surface of guiding head 2, there is the screwed hole 22 upwards extended vertically.
During assembling, press-loading device 1 is vertically arranged, and guiding head 2 is installed on the cylinder bar 11 of press-loading device 1 by screwed hole 22, and is locked by locking nut.When leading head 2 when rising to topmost, the step surface 211 of guiding head 2 is concordant with the lower circle of cylinder-bore seam 4, concordant with justifying bottom of cylinder-bore 5 when guiding head 2 drops to bottom;
When press-loading device 1 is hydraulic cylinder, the oil pipe oil circuit of hydraulic cylinder is equipped with check valve and overflow valve, one-way valve opens when raised, guiding head 2 can be climbed to position as required to support cylinder jacket 3, the closed check valve when press-fiting cylinder jacket 3, overflow valve is opened, and guiding head 2 slowly declines, and at this moment cylinder jacket 3 is slowly depressed simultaneously.
As shown in Figure 5, the concrete steps of the pressing method of the sliding distribution cylinder sleeve of this diesel engine thin-wall comprise:
First, by normal process cleaning engine cylinder block 6, make cylinder block 6 bottom surface down, circulate to press-fiting cylinder jacket post by roller-way 8, now movable rollgang 8 declines, cylinder block 6 is fallen on the supporting plate 7 of location, makes the end of cylinder block cylinder-bore 5 circle fall on the step head 21 of this press-loading apparatus guiding head 2;
Then, the rising under the lifting of press-loading device 1 of guiding head 2, is nested into cylinder body opening seam 4 place, now cylinder jacket 3 is inserted in the O shape circle of step head 21;
Afterwards, under artificial pressure or press pressure hold up effect with the holder of this press-loading apparatus, cylinder jacket 3 is pressed onto in cylinder-bore 5 slowly;
Finally, when the guiding head 2 of this press-loading apparatus drops to minimum point, cylinder block rollgang 8 rises, and guiding head 2 departs from cylinder jacket 3, completes cylinder jacket and press-fits.
The guiding head of this press-loading apparatus rises when rising fast; slowly decline during decline; be conducive to improving productive temp and protection cylinder jacket; guider head is round platform; cylinder jacket is made to import cylinder holes efficiency high; process is press-fited in cylinder jacket; cylinder jacket slowly presses down under the holder of guider head is held up; prevent from press-fiting Process Gas cylinder sleeve to be clashed into; guarantee press-fits quality, thus avoid due to cylinder jacket press-fit improper and cause cylinder liner deformation, bulge loop fracture and then the significant trouble such as the extraordinary wearing and tearing caused and gas leakage lubricating oil carry-over on cylinder sleeve.
Be only a specific embodiment of the present invention above, but the present invention is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
