Accompanying drawing explanation
Fig. 1 is the mounting arrangements schematic diagram of a kind of visual motor stand alone type cylinder sleeve of the present invention;
Schematic diagram is arranged in the dismounting that Fig. 2 is the cylinder sleeve shown in Fig. 1 of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, technological scheme of the present invention is clearly and completely described.
One of the present invention as shown in drawings visual motor stand alone type cylinder sleeve, it comprises cylinder body 14, and described cylinder body 14 is fixed with cylinder sleeve seat 12 by bolt 13, and cylinder sleeve seat 12 provides guiding and supporting effect at vertical direction for independent cylinder sleeve 3.In described cylinder sleeve seat 12, vertically have mounting hole of cylinder sleeve, in described mounting hole of cylinder sleeve, be inserted with the independent cylinder sleeve 3 with mounting hole of cylinder sleeve inwall Spielpassung.Have an annular pass as integral type water jacket 4 in described independent cylinder sleeve 3 inside, described independent cylinder sleeve 3 outer wall is provided with the water-cooling tube joint be communicated with water jacket.Vertically shoulder hole is had in described independent cylinder sleeve 3, the diameter of the upper hole in described shoulder hole is greater than the diameter of lower hole, piston 8 is installed in described shoulder hole, plane silica glass 15 passes through annular pressing plate 16 by multiple uniform bolton at piston 8 top, bolt can adopt 6, for providing visualization window along piston shaft direction.Multiple tracks piston ring 9,10,11 is circumferentially arranged at intervals with, preferably three roads at described piston outer wall.The external diameter of described multiple piston rings (namely not by External Force Acting) is in its natural state greater than the hole internal diameter of the lower hole of shoulder hole, the step wall of described shoulder hole is disposed with lower teflon gasket 6 from bottom to up, annular silica glass 5 and upper teflon gasket 7, for ease of the dismounting of annular silica glass 5, the micro-external diameter being greater than silica glass 5 of internal diameter of the radical-thrust anchor ring of the upper hole of the shoulder hole of independent cylinder sleeve 3, therefore the upper hole of the shoulder hole of annular silica glass 5 and independent cylinder sleeve 3 is Spielpassung, during work, faced by the radical-thrust of upper hole, annular silica glass 5 only plays the effect of contraction of position, annular silica glass 5 does not bear the radial forces applied by independent cylinder sleeve 3, annular silica glass 5 is only clamped by the axial force between independent cylinder sleeve 3 and cylinder cap 1.For the ease of the introducing of laser, symmetrically on the wall surface of the hole of the upper hole in described shoulder hole have two through holes (can be rectangle), laser just can enter firing chamber through through hole and annular silica glass.Firing chamber is the space that annular silica glass inwall and the upper surface of piston and the lower surface of cylinder cap surround.When piston 8 is in top dead center position, in multiple piston ring, the upper-end surface of uppermost piston ring 9 is positioned under the lower end surface of annular silica glass 5, and during to ensure that motor runs, piston ring 9 moves up and down with piston can not scrape annular silica glass 5.The gyration center conllinear of the work anchor ring of described piston 8, independent cylinder sleeve 3, annular silica glass 5, cylinder sleeve 12.Independent cylinder sleeve 3 is fastened on the lower end surface of cylinder cap 1 by cylinder sleeve bolt 2.Preferably around independent cylinder sleeve 3, be provided with shelf (not representing in schematic diagram), the top of described shelf and bottom respectively by bolton on cylinder cap 1 and cylinder body 14, support cylinder cap 1 thus.Described lower teflon gasket, annular silica glass and upper teflon gasket are compressed by the axial force between independent cylinder sleeve 3 and cylinder cap 1 and are arranged in the upper hole of independent cylinder sleeve.
The water jacket 4 of independent cylinder sleeve 3 is casting, has volume large, the feature that thermal conduction effect is excellent.The internal face roughness of preferred independent cylinder sleeve 3 is 1.6, and cylindricity is 0.01.
Working procedure and the principle of apparatus of the present invention are as follows: what the present invention was optical engine provides optic visualization platform, and optical diagnostics research carries out efficiently smoothly based on this platform.That can save that dismounting cylinder cap brings is loaded down with trivial details, thus realizes the dismounting of cylinder sleeve directly, efficiently and simply, for clean cylinder sleeve side visualization window-annular silica glass with that piston head visualization window-plane quartz glass tape comes is convenient.When testing, can at the lateral leadin laser of independent cylinder sleeve, window in the side of laser successively through independent cylinder sleeve, annular silica glass 5 enters in firing chamber, excite the mixed gas in firing chamber, thus produce specific fluorescence, fluorescence is through plane silica glass 15, and the 45 degree of reflecting mirrors be arranged under piston outside this device enter the camera be arranged on outside this device, thus obtain mixed gas image in cylinder.After experiment, cylinder sleeve can be dismantled efficiently so that clean annular silica glass 5 and plane silica glass 15.For adapting to the difference of the in-cylinder pressure that different fuel burning produces, the present invention's cylinder sleeve bolt replaces cylinder bolt to realize the adjustment of pretightening force flexibly.For reaching better heat-transfer effect, temperature control effect and sealing effect, the present invention adopts the large positive displacement water jacket of integral type, replaces traditional cylinder sleeve with the internal face of independent cylinder sleeve.
The step dismantling independent cylinder sleeve is: when taking a seat for avoiding independent cylinder sleeve 3, piston ring shifts out inboard wall of cylinder liner face, scrapes annular silica glass 5, not only damage silica glass 5, and internal face piston ring being reinstalled independent cylinder sleeve is also very loaded down with trivial details.Therefore first the piston plate 8 of motor is arrived lower dead center, four cylinder sleeve bolts 2 of fastening independent cylinder sleeve 3 and cylinder cap 1 are disassembled, rotate slightly independent cylinder sleeve 3, the middle end face of independent cylinder sleeve 3 is made to be seated at the upper end surface of cylinder sleeve seat 12, take out teflon gasket 7 again, take out annular silica glass 5, take out lower teflon gasket 6, complete unloading process, thoroughly clean annular silica glass 5 and plane silica glass 15 afterwards, the step of installing independent cylinder sleeve is: first the piston 8 of motor is coiled to lower dead center, teflon lower levelling plate 6 on pad, load onto the annular silica glass 5 after cleaning, be padded with teflon Upper gasket 7, independent cylinder sleeve 3 is rotated gently the upper-end surface also upwards carried to independent cylinder sleeve 3 to contact with the lower end surface of cylinder cap 1, tension force due to piston ring makes independent cylinder sleeve 3 keep equilibrium position, with torque spanner according to 20 of regulation, 30 and the moment of 40N.m, successively four cylinder sleeve bolts 2 are anchored on cylinder cap 1 symmetrically, the Tightening moment of four cylinder bolts 2 is divided and is increased to 40N.m three times, prevent annular silica glass 5 from concentrating due to stress and cause damage.
Although be described the preferred embodiments of the present invention by reference to the accompanying drawings above; but the present invention is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present invention; do not departing under the ambit that present inventive concept and claim protect, can also make a lot of form, these all belong within protection scope of the present invention.
