Detailed description of the invention
With specific embodiment, the present invention is illustrated by reference to the accompanying drawings.
As shown in Figure 1, 2, the combination dismantling device of a kind of engine piston and flame rings, mainly comprises: supporter, piston swelling device, flame rings provision for disengagement etc.Described supporter is made up of supporting disk 1, handle 4 and nut 11.Described supporting disk 1 is in the form of annular discs, uniform 3 fan-shaped lightening holes 14 on it, and there is a boss at center, upper surface, and boss center is screwed hole, and supporting disk 1 lower surface is uniform 3 T-shaped guide grooves 8 and a pair shoulder hole along the circumferential direction; Described handle 4 takes the shape of the letter U, and cross section is circular, the external screw thread that the handle 4 two ends section of having is thinner, and handle 4 is fixed on supporting disk 1 with nut 11 through after a pair shoulder hole on supporting disk 1 end face by two ends.Described piston swelling device is made up of tightening piece 9, spring 10, push rod 7, boosting-rod 5 and bolt II 6.Described tightening piece about 9 points two parts, upper T shape part is arranged in the T-shaped guide groove 8 on supporting disk 1, and with guide groove 8 matched in clearance, sector structure one end cylindrical of bottom has half slot, the other end is driven bulb 13; Described spring 10 is arranged in the half slot of tightening piece 9; Described push rod 7 top is column structure, and cylindrical is screw thread, is screwed in the screwed hole at supporting disk 1 boss center, have a screwed hole apart from upper end certain distance, push rod 7 bottom is active bulb 12, and push rod 7 center is unthreaded hole, described bolt II 6, through unthreaded hole, is screwed in the screwed hole in the middle of piston crown; Described boosting-rod 5 is 2, is screwed into respectively in the screwed hole of push rod 7 upper end.Described flame rings provision for disengagement, by locating piece 3 and bolt I, is 3, and described locating piece 3 is cuboid, side has 1 screwed hole, locating piece 3 bottom surface circumferentially uniform welding in the upper surface of supporting disk 1; Described bolt I 2 is screwed in the screwed hole of locating piece 3, and locating piece 3 certain distance is exposed in bolt I 2 termination.
Piston and flame rings unloading process simultaneously in the utility model: as Fig. 3, first supporting disk 1 is attached on piston 18 end face, observes from the fan-shaped lightening hole supporting disk 1, guarantees that initiatively bulb 12 has entered with driven bulb 13 and engages; Rotating boosting-rod 5 makes push rod 7 descending, the active bulb 12 promoting lower end extrudes driven bulb 13, tightening piece is radially slided in T-shaped guide groove 8, makes the cylindrical of tightening piece 9 be pressed on combustion chamber throat 17, until the rotation of complete limited piston 18, stop operating boosting-rod 5; By the unthreaded hole of bolt II 6 through push rod 7, be connected with the screwed hole in the middle of the combustion chamber of piston 18, guarantee that the seal face of bolt II is close to push rod 7 end face.Now, piston and engine is first made to depart from tightening state, slowly the dynamic engine of dish makes piston 18 up afterwards, when bolt I 2 moves to the removal hole position on flame rings 16 cylindrical, and rotating bolt I 2, bolt head is made to stretch into flame rings removal hole certain depth, continuation dish moves engine, and piston 18 drives flame rings 16 up together, when piston 18 arrives top dead centre, manually to hold with a firm grip handle 4, piston 18 and flame rings 16 are proposed in cylinder jacket 15.
Piston Process is dismantled separately: repeat said process in the present invention, first complete the installation of instrument and piston 18, then piston 18 and engine is made to depart from stationary state, and slowly the dynamic engine of dish makes piston 18 go upward to top dead centre, manually to hold with a firm grip handle 4, piston 18 is proposed in cylinder jacket 15, and whole unloading process, does not make bolt I 2 be connected with the removal hole in flame rings 16.
Flame rings process is dismantled separately: repeat said process in the present invention, first complete the installation of instrument and piston 18, piston 18 and engine is made still to keep installment state, then slowly the dynamic engine of dish makes piston 18 up, when bolt I 2 moves to the removal hole position on flame rings 16 cylindrical, and rotating bolt I 2, bolt head is made to stretch into flame rings removal hole certain depth, continuation dish moves engine, and piston 18 drives flame rings 16 up together, and flame rings 16 is ejected cylinder jacket 15.
Installation process of the present invention: install flame rings 16 and need manual directly loading in cylinder jacket 15, when piston 18 is installed, first the supporting disk 1 of dismantling device is attached on piston 18 end face, observe from the fan-shaped lightening hole supporting disk 1, guarantee that initiatively bulb 12 has just entered with driven bulb 13 to engage, now rotating boosting-rod 5 makes push rod 7 descending, the active bulb 12 promoting lower end extrudes driven bulb 13, tightening piece 9 is radially slided in T-shaped guide groove 8, the cylindrical of tightening piece 9 is made to be pressed on the combustion chamber throat 17 of piston 18, until the rotation of complete limited piston 18, stop operating boosting-rod 5, again bolt II 6 is passed the unthreaded hole on push rod 7, be connected with the screwed hole in the middle of the combustion chamber of piston 18, guarantee that the seal face of bolt II 6 is close to push rod 7 end face, then carrying handle 4, the piston pin hole axis of piston 18 is turned to and engine crankshaft axis being parallel, in slowly installing piston into cylinder being overlapped, complete piston and engine fastening after unclamp bolt II 6, bolt II 6 is made to depart from the connection with piston 18, rotating backward boosting-rod 5 makes push rod 7 up, active bulb 12 on push rod 7 is thrown off with driven bulb 13, tightening piece 9 radially inwardly slides and throws off with the combustion chamber throat 17 of piston 18 under the effect of spring 10 in T-shaped guide groove 8, dismantling device is separated with piston 18, now hold handle 4 and propose instrument, complete the installation of piston.
