The specific embodiment
Below in conjunction with accompanying drawing, a specific embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of the specific embodiment.
As shown in Figure 1 to Figure 3, cylinder head valve guide bushing press mounting tool of the present utility model, be used for the valve guide bushing (not shown) is pressed into the corresponding bottom outlet of cylinder head (not shown), comprise pressing plate 1, pressure head 7, guide post 2 and be used for support cylinder head base 12, guide post 2 is installed on the base 12 by guide post trip bolt 13, pressing plate 1 is sleeved on the guide post 2 and can slides up and down along guide post, pressure head 7 is installed in the bottom of pressing plate 1 by pressure head trip bolt 5, can make things convenient for the replacing of pressure head 7.Pressure head 7 is established steel wire strainer 6 with the junction of valve guide bushing, this strainer is to establish groove (as shown in Figure 2) in pressure head 7 relative both sides, this groove is used for a ccontaining U type elastic wire (not shown), after pressure head 7 inserted valve guide bushings, elastic wire was outwards oppressed the frictional force that valve guide bushing forms a vertical direction and is come off under the gravity effect to avoid valve guide bushing.Cause damaging cylinder head for avoiding pressing plate 1 excessively to press down, press-mounting stroke limited block 3 is established in pressing plate 1 bottom.
As shown in Figure 1, 2, press-fit the accurate location that process realizes pressure head and cylinder head for making, this press mounting tool also comprises the cylinder head detent mechanism, and the cylinder head detent mechanism comprises guide pad 11, pre-determined bit seat 15, pre-determined bit block 16 and pre-determined bit round pin 14; Also comprise locating piece 10, alignment pin and alignment pin elevating mechanism.Guide pad 11 is used for the guiding that cylinder head is gone into a process along base 12 horizontal expansion settings.Pre-determined bit seat 15 is arranged at cylinder head goes into a starting point one side and is fastenedly connected with base 12, and pre-determined bit block 16 is connected with pre-determined bit seat 15 pivots by pre-determined bit round pin 14, and the pivot tie point is positioned at close base 12 1 sides on the pre-determined bit block.Locating piece 10 is positioned on the base and goes into a direction along cylinder head and extend and be provided with, cylinder head go in the process locating piece upper surface all the time with the cylinder head lower face applying of sliding mutually.Alignment pin is installed on the base 12, comprises location round pin 17 and location water chestnut pin 18, and its position, spacing are suitable with position, the spacing of the corresponding bottom outlet of cylinder head respectively, so that realize inserting the location.The alignment pin elevating mechanism specifically comprises the bolt rod 9 of horizontally set and is located at handle 8 on the bolt rod 9, location round pin 17 is sold with the location water chestnut and is offered inclined-plane (being round pin inclined-plane, location 171 and the water chestnut pin inclined-plane 181, location among Fig. 1) on 18 respectively, inclined-plane (being the bolt rod inclined-plane 91 among Fig. 1) is also offered in corresponding position on the bolt rod 9, the bolt rod inclined-plane 91 of two alignment pin inclined-planes and relevant position fits adaptive, after cylinder head is gone into the position, horizontal pushing handle moves horizontally bolt rod, because the effect on inclined-plane is risen alignment pin and is inserted the accurate location of realizing cylinder head in the corresponding cylinder head bottom outlet.
The detailed process of introducing the cylinder head location below and press-fiting:
Valve guide bushing that at first will be to be press-fited is inserted in two pressure heads 7 among Fig. 2, because the effect of steel wire strainer 6, valve guide bushing can not come off; Cylinder head is placed on into a starting point side, i.e. the top of pre-determined bit seat 15 in left side among Fig. 1, this moment, the cylinder head bottom surface was pushed down the projection of the right-hand member of pre-determined bit block 16, the 16 left side perks of pre-determined bit block; Then along the direction horizontal sliding cylinder head of guide pad, fit and slide in the upper surface of cylinder head bottom surface and locating piece 10, go into the position fully to base 12 until cylinder head, pre-determined bit block 16 left side fallings under gravity effect this moment, right-hand end is upspring again, and cylinder head is pulled back props up pre-determined bit block 16 right-hand end projectioies; Right direction horizontal sliding handle 8 to Fig. 1, under the interaction on alignment pin inclined-plane and bolt rod inclined-plane 91, make two alignment pins rise, just insert in the corresponding bottom outlet of cylinder head, realize the accurate location of cylinder head, the valve guide bushing on this moment pressure head 7 just be positioned at valve guide hole on the cylinder head directly over; At last, under the vertical depression effect of the forcing press above the pressing plate 1, valve guide bushing vertically is pressed in the guide hole of cylinder head, press-mounting stroke limited block 3 can effectively be controlled and press-fit height, after being press-fit into place, and pressure-raising plate on the forcing press, this moment since the frictional force between pressure head 7 and the valve guide bushing less than the frictional force between valve guide bushing and the guide hole, last pressure-raising plate can not taken valve guide bushing out of, so far, press-fits end-of-job.
Press mounting tool of the present utility model location is more accurate, and greatly reduces operator's labour intensity.
More than disclosed only be a specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
