Background technology
The sideshake of piston ring refers to after being packed into piston that the gap between piston ring end face and piston ring groove, sideshake can prevent
Piston ring expanded by heating and it is stuck in cylinder.If the sideshake of piston ring does not meet technology requirement, it be easy to cause engine and alters
Gas alters oil, and stuck scuffing of cylinder bore, movement parts are easy to wear, and lubrication oil consumption is abnormal, seriously affects engine power performance, reliability.
Stringent engine development experiment process is required for arranging whether the sideshake of test piston ring meets design requirement, right
In the detection method of straight-flanked ring sideshake, horizontal positioned piston, tested piston ring is freely fallen into annular groove, with the clearance gauge of suitable thickness
Directly detect sideshake size.
For cambridge ring, piston ring groove is taper-face contact, and the measurement of current cambridge ring sideshake now is generally using dismounting
Piston crank mechanism is to related components detection relative dimensions (piston ring thickness, the annular groove of piston are wide), then data measured is led to
It crosses and is calculated.But the angle of cambridge ring and void need dedicated equipment and instrument like the relative dimensions such as central diameter parameter
Device measures, heavy workload, and very time-consuming, and often one-shot measurement and calculating just needs several days, complete to the node of R＆D work
Into very unfavorable.
The information for being disclosed in the background section is merely intended to increase the understanding to the general background of the utility model, and
It is not construed as recognizing or implies that the information structure has been existing well known to persons skilled in the art in any form
Technology.

Description of the drawings
Fig. 1 is the front view of the detection device of piston ring side clearance according to the present utility model；
Fig. 2 is the left view of the detection device of piston ring side clearance according to the present utility model；
Fig. 3 is the detects schematic diagram of the detection device of piston ring side clearance according to the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality
New protection domain is not restricted by specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " comprising " or its change
It changes such as "comprising" or " including " etc. and will be understood to comprise stated element or component, and do not exclude other members
Part or other components.
It as shown in Figure 1 to Figure 3, can be with according to the detection device of the piston ring side clearance of specific embodiment of the present invention
The piston ring side clearance under the true assembled state of piston ring is detected with clearance gauge, detection device includes sleeve 1 and two clearance gauges 4, sleeve 1
Internal diameter 3 it is consistent with the internal diameter for the cylinder jacket that piston ring to be detected is installed, actually the simulation cylinder jacket of real engine, best
It is identical with structure, the material of actual installation cylinder jacket, (same to material, with just is made according to the cylinder jacket size of actual use
Degree).Equally spaced setting is there are four detection window 2 in the circumferential wall of sleeve 1, and detection window 2 is used for stretching into clearance gauge 4, the detection
Device is by judging it is whether qualified whether clearance gauge 4 and piston ring side clearance match to detect piston ring side clearance.Detection window 2 is designing
When, length be slightly larger than common clearance gauge width, the width of detection window 2 be slightly larger than or equal to surveyed piston ring groove width i.e.
It can.Preferably, detection window 2 is elongated hole or rectangular opening.When detection window 2 is rectangular opening, detection window length for 20~
30mm, width are suitable for 4~8mm.The detection device is by judging whether clearance gauge 4 and piston ring side clearance match to detect piston ring
Whether sideshake is qualified, realizes the actual environment of simulation piston ring, piston and cylinder jacket assembling, measurement is simple, as a result accurately.
It is the application method of the detection device of the present embodiment below：
Assemble and disassemble step：Piston ring is attached in corresponding piston ring groove, is then fitted into them in detection device together, and
Entire piston ring excircle side face is made to be in 4 detection windows 2, surveyed piston ring side clearance can be observed in detection window 2
Position.Usually, piston ring include a ring 5, two rings 6, oil ring 7, be fitted into auxiliary detection device, and make piston it is forward and backward,
Into, ranking put in 4 detection windows 2, the position of surveyed piston ring (ring 5) sideshake can be observed in detection window 2
It puts.
Characterization processes (measurement) step：It is inserted respectively from the detection window of relative position with suitable, same thickness clearance gauge
Among entering piston ring side clearance, pull with hand clearance gauge slightly exert oneself subject to.Specifically, two clearance gauges can be adjusted to piston ring side
The technology claimed range thickness of gap is inserted into respectively among piston ring side clearance position, anterior-posterior or into-row relative position can fill in
Subject to clearance gauge.
Judgment step：By measurement clearance gauge thickness value compared with the piston ring side clearance that technology requires, if clearance gauge thickness
Not in the technology claimed range of piston ring side clearance, then the piston ring side clearance is overproof (unqualified).Specifically, two clearance gauges can be distinguished
It is inserted among sideshake position, it is firmly slightly qualification to pull with hand clearance gauge.If one cannot be inserted into (or two) in sideshake position,
Or can be inserted into but it is very loose be all judged as overproof, this method can quickly judge whether piston ring side clearance overproof, accuracy and efficiency
It is high.
To sum up, the detection device of the piston ring side clearance of the present embodiment, design is reasonable, easily manufactured, can correctly simulate
The actual environment of piston ring assembling, particularly solve as the detection method of cambridge ring sideshake is complicated, it is necessary to dedicated equipment and
The problem of apparatus measures could measure, and measuring principle meets actual requirement, and operating process is simple, and work efficiency is high, measurement
As a result correct feedback research and development need.
The description of the foregoing specific exemplary embodiment to the utility model is in order to illustrate and illustration purpose.These
Description is not wishing to for the utility model to be defined to disclosed precise forms, and it will be apparent that according to the above instruction, can carry out
Many change and variations.The purpose of selecting and describing the exemplary embodiment is that explain the certain principles of the utility model
And its practical application, so that those skilled in the art can realize and utilize a variety of examples of the utility model
Property embodiment and various chooses and changes.The scope of the utility model is intended to by claims and its waits similar shapes
Formula is limited.
