Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described:
As shown in Figures 1 to 6, a kind of cylinder sleeve movable type optical engine piston ring rapid dismounting apparatus, it is made up of device body, including guide ring 13, thrust washer 11, fastening bolt 12 and nut 10, the outside diameter d of guide ring 131With height h1Identical with the quartz glass window 3 being fixed on cylinder sleeve 6, ensure that guide ring 13 can replace the quartz glass window 3 of annular, the middle part of guide ring 13 is provided with conical through-hole, utilizes the positioning relation between former quartz glass window 3 and cylinder sleeve 6 annular groove to make conical through-hole keep coaxial with cylinder sleeve 6；Aperture d bottom conical through-hole3Identical with the internal diameter of cylinder sleeve 6, it is ensured that the mode that in the Piston volume tube 5 in cylinder sleeve 6, each piston ring can be transferred through sliding enters in conical through-hole；The aperture d at conical through-hole top2More than piston ring external diameter in a free state, to ensure that piston ring in a free state can from turnover conical through-hole in the hole at conical through-hole top, the inside surface roughness of conical through-hole is suitable with cylinder sleeve 6 inside surface roughness, and the in use grease of uniform application suitable thickness, to reduce piston ring abrasion of sealing surface when passing in and out conical through-hole.Thrust washer 11 is fixed on cylinder sleeve 6 by fastening bolt 12 and nut 10, and the middle part of thrust washer 11 is provided with circular hole, the internal diameter d of circular hole4It is greater than d2And less than d1, in order to avoid producing to interfere to piston ring, the thickness of thrust washer 11 wants suitable, and while strictly fitting with cylinder sleeve 6 in the bottom surface ensureing guide ring 13, thickness is unlikely to excessive, to obtain sufficiently large guide ring 13 installing space；Manually dish turns engine crankshaft, makes lengthened piston 7 to pump, and coordinates the position of portable cylinder sleeve 6 to realize the fast assembling-disassembling of piston ring.
The specifically used method of this utility model device is as follows:
In optical engine course of normal operation, as it is shown in figure 1, portable cylinder sleeve 6 is fastened on cylinder cap 1 under the effect of bolt 2, the compacted formation sealing surface of upper and lower surface of the quartz glass window 3 between cylinder sleeve 6 and cylinder cap 1.In the process of removing of piston ring, first dish dynamic crankshaft makes lengthened piston 7 move down lower dead center, demounting bolt 2, cylinder sleeve 6 is moved to bottom in cylinder sleeve base 8, quartz glass window 3 is taken out, after quartz glass window 3 and piston top quartz window 4 are cleaned process, load guide ring 13, guide ring 13 uniform application moderate lubrication oils and fats in conical through-hole in advance before loading, it loads thrust washer 11 up subsequently, fix with fastening bolt 12 and nut 10, then dish dynamic crankshaft makes lengthened piston 7 move up, Piston volume tube 5 from top to bottom passes sequentially through the conical through-hole of guide ring 13, until lengthened piston 7 is positioned at top dead centre, Piston volume tube 5 is completely in free state, piston ring can be cleaned and lubricated subsequently, as shown in Figure 2.
Load in portable cylinder sleeve 6 process at Piston volume tube 5; first keep basic and cylinder sleeve the centrage of piston ring position substantially aligned; guarantee that piston ring is unlikely to encounter the upper surface of guide ring 13 in folding process; then dish dynamic crankshaft makes lengthened piston 7 descending; entering in cylinder sleeve 6 until the piston ring on Piston volume tube 5 passes sequentially through guide ring 13 from bottom to top, piston ring installs.Dismounting tight fixed bolt 12 and nut 10, take out thrust washer 11 and guide ring 13.Finally load quartz glass window 3, and cylinder sleeve 6 is moved to cylinder cap 1 coordinate place, utilize bolt 2 to be tightened by cylinder sleeve 6 by the pretightning force specified.
