Abstract
The utility model relates to a transition sleeve for feeding a piston with a ring set. The transition sleeve for feeding the piston with the ring set is applied to cylinder feeding of the piston with the ring set. The transition sleeve for feeding the piston with the ring set is a cylinder, wherein the inner wall of one end of the cylinder is opened outwards to form a horn mouth, and a tenon which is provided with an opening for being inserted into a cylinder body, and is connected with the position of a chamfer is arranged at the other end of the cylinder. The tenon is formed by the inner wall of the cylinder by extending outwards towards an end opening, and the length of the tenon is no less than the distance of the axial depth of the chamfer of the cylinder body and the thickness of a piston ring. The transition sleeve for feeding the piston with the ring set has the advantages that the piston with the ring set can be successively fed into the cylinder body, operation of the whole cylinder feeding process is easy, and the transition sleeve for feeding the piston with the ring set is time-saving and labor-saving.
Description
Technical field
The utility model relates to cylinder spacer shell under the band group piston, is applied to band group piston and enters cylinder.
Background technology
All piston rings use the piston ring groove of must packing into first, after whole piston rod is assembled in the cylinder body.People directly advance band group piston in the cylinder body with hand, but run into the difficulty that the piston ring difficulty enters cylinder port in progradation.
Along with the requirement of gasoline engine development discharging aspect is more and more higher, be low friction loss to the requirement of piston ring group, low oil consumption.The development of piston ring is lightweight, low-tension, and also by the trend development of original 3mm toward 2mm, the thickness of doctor blade ring is also developed toward 0.3mm by original 0.4mm like this for piston ring slimming, particularly 3 Combined-type sheet-type oil rings.The problem of the bad lower cylinder of piston ring also is on the rise.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point of the prior art, provides a kind of band group piston is pushed cylinder spacer shell under the band group piston in the cylinder body swimmingly.
The purpose of this utility model can realize by following technical proposals: cylinder spacer shell under the band group piston, it is characterized in that a cylinder, and cylinder one end inwall externally opens horn mouth, and other end band inserts cylinder port and the tenon matched with the chamfering place; Tenon is formed to the port extension by cylinder inner wall, and length is not less than the poor of cylinder body chamfering axial depth and piston ring thickness.
The utlity model has following advantage: the utility model cooperates with cylinder port by tenon, in the gap at cylinder body chamfering place less than the gauge of doctor blade ring, thereby band group piston also just avoided doctor blade ring to be stuck in the cylinder body chamfering after pushing from horn mouth, and then in the cylinder body of being packed into smoothly.Whole process operation is simple, and is time saving and energy saving.
Description of drawings
Accompanying drawing 1 is the utility model structure cutaway view.
1 is horn mouth among the figure, the 3rd, and tenon.
Fig. 2 is that the left side of Fig. 1 is looked.
Fig. 3 is the right view of Fig. 1.
It is combined and band group piston pushed decomposing schematic representation in the cylinder body with cylinder body when Fig. 4 the utility model uses.
5 is cylinder bodies among the figure, the 7th, and the utility model, the 9th, piston, the 11st, piston ring.A is cylinder body chamfering axial depth, and b is tenon length, and c is piston ring thickness.
The specific embodiment
The utility model is further described below in conjunction with accompanying drawing.Cylinder spacer shell under the band group piston, it is a cylinder, and cylinder one end inwall externally opens horn mouth (1), and other end band inserts cylinder port and the tenon (3) matched with the chamfering place; Tenon (1) is formed to the port extension by cylinder inner wall, and length b is not less than the poor of cylinder body chamfering axial depth a and piston ring (doctor blade ring) thickness c.
During use, the utility model tenon (3) is inserted into cylinder body (5) mouth, piston (9) pushes from horn mouth (1), be pushed into when relevant, piston ring (11) is compressed in the plug ring groove and makes piston ring face concordant with the outer surface of piston, when entering cylinder body (5) mouth, the end play (a-b) at tenon (3) port and cylinder body chamfering place is less than the gauge c of piston ring, piston (9) just can successfully push connecting rod first in the cylinder body, the back piston skirt section enters, last piston crown comprises that piston ring pushes in the cylinder body by spacer shell with hand, finishes cylinder under the piston rod group.So just solved cylinder hard problem under the piston ring group, whole process operation is simple, and is time saving and energy saving.
Claims (1)
1. cylinder spacer shell under the band group piston is characterized in that a cylinder, and cylinder one end inwall externally opens horn mouth (1), and other end band inserts cylinder port and the tenon (3) matched with the chamfering place; Tenon (1) is formed to the port extension by cylinder inner wall, and length is not less than the poor of cylinder body chamfering axial depth and doctor blade ring thickness.
