Abstract
The utility model discloses an installation guiding device of an engine piston connecting rod, which is provided with a port; the port is in a horn shape, the diameter of the upper end of which is large and the diameter of the lower end is small; the diameter of the lower end is the same with the size of the cylinder diameter of an engine; the engine is provided with a gas ring and an oil ring, and the gas ring and the oil ring under a free state are larger than the cylinder diameter of the engine; through the installation guiding device of an engine piston connecting rod, the piston presses the upper end of the port to the lower end thereof and then enters a cylinder sleeve, thus realizing the fast installation of the piston. The utility model can be widely applied to the installation processes of various kinds of engines.
Description
Technical field
The utility model relates to a kind of installation and guide device, relates in particular to a kind of installation and guide device of engine piston connecting rod.
Background technology
At present, from the structure of engine as can be known, engine piston all can have compression ring and oil ring.Compression ring and oil ring all are bigger than piston diameter (cylinder sleeve diameter) in free state, and piston is before assembling, and compression ring and oil ring all are to be in free state.When not having guider, because compression ring and oil ring, piston is difficult to put into cylinder sleeve of engine, has had a strong impact on productive temp, has increased operative employee's labour intensity.Therefore, made a kind of engine piston connecting rod installation and guide device.Solved a great problem in the engine assembling process.
The utility model content
The purpose of this utility model is, at the difficult problem of available engine piston rod assembling, provides a kind of and can guarantee the quality, protect beat, the installation and guide device of engine piston connecting rod easy to use.Installation and guide device has a port, and port is up big and down small diameter, and lower end diameter and engine bore size is consistent, and piston is depressed into the lower end from the upper end of port and enters cylinder sleeve, and Fast Installation is simple in structure, easy to manufacture, easy to install.
The utility model provides: a kind of installation and guide device of engine piston connecting rod comprises: the guider body, described guider has a port, described port is that upper end diameter is big, lower end diameter is little, form a horn shape, described lower end diameter is consistent with the engine bore size, and the outer wall of described installation and guide device has reticulate pattern.
The top and bottom ring of installation and guide device has boss, non-end face of described boss and outer wall arc transition in one week of outer wall.
The inner and outer wall upper surface of installation and guide device all is provided with chamfering.The outer wall lower surface of described installation and guide device is provided with chamfering.
There are one section and engine bore transition annulus of the same size in the lower end of installation and guide device.
The lower surface of installation and guide device and inwall are connected with the lower surface of an outer chamfering or described installation and guide device and do a recessed circular groove, and described outer chamfering is consistent with chamfer angle in the cylinder sleeve of engine inside wall of cylinder upper end, and size is consistent.Described recessed circular groove is consistent with cylinder sleeve of engine upper surface boss size.
The advantage of guider of the present utility model is, by described piston rod installation and guide device, piston is depressed into the lower end from the upper end of described port, thereby enters in the cylinder sleeve, realizes the piston Fast Installation.And this guider is simple in structure, easy to process and with low cost and light and handy, the operation simple and convenient.

Mark the following drawings mark thereon in conjunction with the accompanying drawings:
Chamfering (3), the recessed circular groove in guider lower surface (4), cylinder jacket upper surface (5), Piston and rod assembly (6), the installation and guide device (7) of engine piston connecting rod, cylinder jacket (8) outside guider upper end (1), transition annulus (2), the guider lower surface.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
Be guider as shown in Figures 1 to 4, Fig. 5 is to Figure 7 shows that air cylinder sleeve of engine, wherein Fig. 1 and Fig. 2 are a kind engine piston connecting rod installation and guide device, be fit to the engine of guiding cylinder liner construction for chamfering in cylinder jacket upper end inwall has, as Fig. 6, the location of described guider and cylinder jacket is the engagement by inside and outside chamfering.Fig. 3 and Fig. 4 are another kind engine piston connecting rod installation and guide device, be fit to the engine of guiding cylinder liner construction for chamfering in cylinder jacket upper end inwall does not have, as Fig. 7, the location of described guider and cylinder jacket is the engagement by the recessed circular groove of described guider and cylinder jacket upper end boss.
In the piston rod assembling process, the installation and guide device of engine piston connecting rod (7) is put on the cylinder jacket (8), Piston and rod assembly (6) is put into the installation and guide device (7) of engine piston connecting rod, top land with hand propelled Piston and rod assembly (6), piston will prolong the inwall of the installation and guide device (7) of engine piston connecting rod, progress into transition annulus (2), this moment, compression ring and oil ring became contraction state by original free state, through transition annulus (2), piston just can enter cylinder jacket smoothly, and the guiding work of the installation and guide device of engine piston connecting rod (7) is finished.
It should be noted that: above embodiment is only unrestricted in order to explanation the utility model, the utility model also is not limited in above-mentioned giving an example, all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
