Diesel engine cylinder cover copper bush of fuel injector of the present utility model to press-fit external member simple and reasonable, what the rod that rises that has a guide part by design ensured that the annular groove of O type circle and diesel engine cylinder cover oil injector hole fits completely packs into, when press mounting copper can be avoided, produce the trimming of O type circle, to improve filling rate and the sealing of O type circle in annular groove, so improve diesel engine cylinder cover copper bush of fuel injector press-fit quality and press-fit efficiency diesel engine cylinder cover copper bush of fuel injector press-fit external member.
Detailed description by way of example but unrestriced mode has illustrated the disclosure, should be understood that the realization that can be combined by independent realization or with other aspects in various aspect of the present disclosure below.This description clearly enables those skilled in the art to manufacture and uses us to believe for new and non-obvious improvement, describe some embodiment, alternative, modification, alternative and system applies, comprised the current best mode that is considered to carry out the utility model principle of describing in this description.In the time describing element or feature and/or embodiment, be intended to expression titled with " one " " one " " be somebody's turn to do " and " described " and there are one or more in element or feature.Term " comprises " that " comprising " and " having " is intended to is comprising property, and also has extra element or feature beyond being illustrated in those specifically described elements or feature.
As depicted in figs. 1 and 2, the concrete structure that press-fits external member of this diesel engine cylinder cover copper bush of fuel injector comprises: rise rod 1, manual depression bar 2 and gland 3, and wherein, the rod 1 that rises play the guiding role in O type circle process of press in, and guiding O type circle evenly packs in oil injector hole annular groove.Manual depression bar 2 press-fits copper bush of fuel injector and carries out craft and press-fit in advance for treating.Gland 3 is connected with hydraulic machine piston, treats to press-fit copper bush of fuel injector and carry out machinery and be pressed into, until gland 3 end faces and the laminating of copper sheathing end face, and copper sheathing head is pressed in the correspondence position of cylinder head fuel injector hole simultaneously.What the rod that rises that this diesel engine cylinder cover copper bush of fuel injector has a guide part by design ensured that the annular groove of O type circle and diesel engine cylinder cover oil injector hole fits completely packs into, when press mounting copper can be avoided, produce the trimming of O type circle, to improve filling rate and the sealing of O type circle in annular groove, so improve diesel engine cylinder cover copper bush of fuel injector press-fit quality and press-fit efficiency diesel engine cylinder cover copper bush of fuel injector press-fit external member.
As shown in Figure 1, the rod 1 that rises is for cylindric, and lower end head has taper guide section 11, and taper guide section 11 is back taper, and tip, bottom is also laid with guiding bulb 12; Rod 1 the upper end afterbody that rises has the flange 13 of radial protrusion.Taper guide section 11 play the guiding role in O type circle process of press in, can guide O type circle evenly to pack in oil injector hole annular groove.In the time that the excellent 1 afterbody flange 13 that rises contacts with top surface of cylinder cover, the installation of O type circle, can extract the rod 1 that rises by hand.The rod 1 that rises adopts nylon material, can effectively reduce the scratch of 1 pair of cover of rod O type circle thereon that rises.
As shown in Figure 2, manual depression bar 2 is cylindric, and lower end head has the outer peripheral face 21 with copper bush of fuel injector inner peripheral surface adaptation to be press-fited, and upper end afterbody has the flange 22 of radial protrusion.While press-fiting copper bush of fuel injector, the manual oil injector hole of first copper bush of fuel injector to be press-fited being put into cylinder cap, when contacting with O type circle, copper sheathing cylindrical produces after resistance, make depression bar 2 by hand that copper sheathing is continued down to press-fit, until manual depression bar afterbody flange 22 is while contacting with top surface of cylinder cover, copper sheathing precompressed completes, and can by hand manual depression bar be extracted.
Gland 3 is cylindric, and lower end head has copper sheathing pressure-mounting head, for compressing from copper bush of fuel injector to be press-fited lower end inner face, copper sheathing head is pressed in the oil injector hole correspondence position of cylinder cap.The upper end afterbody of gland 3 has hydraulic press connecting portion, press-fits copper bush of fuel injector and carries out machinery and be pressed into for being connected with hydraulic machine piston, treating.
Fuel injector copper sheathing pressure-mounting process is as follows:
First, by hand O type circle 4 is enclosed within and is risen on rod 1, because excellent 1 material that rises is nylon, can effectively reduce the scratch to O type circle;
As shown in Figure 3, then, by hand the rod 1 that rises is pressed in the oil injector hole of cylinder cap 5 together with O type circle 4, due to the excellent 1 head band taper guide section 11 that rises, can in process of press in, play the guiding role, guiding O type circle 4 evenly packs in oil injector hole annular groove.In the time that the excellent 1 afterbody flange that rises contacts with cylinder cap 5 end faces, 4 installations of O type circle, can extract the rod 1 that rises by hand.
As shown in Figure 4, the manual oil injector hole of copper sheathing 6 being put into cylinder cap 5 again, when contacting with O type circle 4, copper sheathing 6 cylindricals produce after resistance, make depression bar 2 by hand that copper sheathing 6 is continued down to press-fit, until manual depression bar 2 afterbody flanges are while contacting with the end face of cylinder cap 5, copper sheathing 6 precompressed complete, and can by hand manual depression bar 2 be extracted.
As shown in Figure 5, finally gland 3 is connected with hydraulic machine piston, aims at copper sheathing 6 and be at the uniform velocity pressed into, until the lower end inner face laminating of the copper sheathing pressure-mounting head lower surface of gland 3 and copper sheathing 6, and the head of copper sheathing 6 is pressed in cylinder cap 5 oil injector hole correspondence positions simultaneously.After having press-fited, drive gland 3 to depart from cylinder cap 5 by hydraulic machine piston.
This diesel engine cylinder cover copper bush of fuel injector press-fit external member by the use rod 1 and manual depression bar 2 that rises, compress before copper sheathing 6 at the final hydraulic press that uses, O type circle 4 and copper sheathing 6 are installed in the oil injector hole of cylinder cap 5 exactly, and the trimming that has effectively prevented from press-fiting O type circle 4 in process produces.
To sum up, this diesel engine cylinder cover copper bush of fuel injector to press-fit external member simple and reasonable, what the rod that rises that has a guide part by design ensured that the annular groove of O type circle and diesel engine cylinder cover oil injector hole fits completely packs into, when press mounting copper can be avoided, produce the trimming of O type circle, to improve filling rate and the sealing of O type circle in annular groove, so improve diesel engine cylinder cover copper bush of fuel injector press-fit quality and press-fit efficiency diesel engine cylinder cover copper bush of fuel injector press-fit external member.
Finally it should be noted that: above embodiment is only in order to illustrate the utility model and the described technical scheme of unrestricted the utility model; Therefore, although this description has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can modify or be equal to replacement the utility model; And all do not depart from technical scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in claim scope of the present utility model.
