Description

Simple and easy fluid pressure type cylinder sleeve is changing device more

Technical field

The utility model relates to a kind of locomotive engine repairing and uses hand-operated tools, and specifically a kind of simple and easy fluid pressure type cylinder sleeve is changing device more.

Technical background

In the engine overhaul process of vehicle, the replacing of cylinder sleeve be an extremely take a lot of work, time-consuming, the effort work.Cylinder sleeve dismounting used tool mainly is a pull bar, and the pull bar bottom has pallet, the pull bar top socket support member and the nut that spins.By constantly pulling nut with spanner, make on the pull bar and carry, could drive pallet the old cylinder sleeve in the body is extracted gradually.And being pressed into of new cylinder sleeve then is to place a block plate thereon, by continuous hammering, cylinder sleeve little by little could be pressed in the body.

The utility model content

The purpose of this utility model just provides and a kind ofly saves labor, simple and easy fluid pressure type cylinder sleeve easy to operate and use changing device more.

The purpose of this utility model be achieved in that this cylinder sleeve of engine more changing device be that the basal disc on locating ring dish and top is fixedlyed connected by vertical rod, movable disk under the vertical rod upper sleeve through, last movable disk is fixedly connected with following movable disk by interting the connecting rod of basal disc; Be hung with pull bar in following movable disk bottom surface, the pull bar lower end connects pallet.The locating ring dish is fixed on the cylinder sleeve upper brim of body, and the lower tray that extend into the pull bar in the cylinder sleeve is stuck in the end opening of cylinder sleeve, and the pull bar upper end is hung with following movable disk and joined.Put into a hydraulic jack then between basal disc and last movable disk, by pushing the handle of jack, will go up movable disk jack-up upwards gradually, the vertical rod by joining with it, movable disk, pull bar and pallet down can progressively be extracted body with cylinder sleeve.Move old cylinder sleeve, take pull bar, put new cylinder sleeve again, with the jack transposition, put between basal disc and the following movable disk again.Push jack handle,, can will descend the new cylinder sleeve of movable disk and its underpart progressively to be pressed in the body, thereby finish the replacing operation of cylinder sleeve because basal disc is motionless.

The utility model cooperates by the cross-under of the adjustable shelf that a pedestal that is composed of a fixed connection by locating ring dish, basal disc and vertical rod and one are set are composed of a fixed connection by upper and lower movable disk and connecting rod, be equipped with the roof pressure effect that hydraulic jack withstands on diverse location, can finish extracting and push operation of cylinder sleeve.This twisting than past dependence manpower is extracted the mode of operation that is pressed into hammering and is wanted much laborsaving, much quick, but also can avoid being pressed at paddle type mill the damage of the new cylinder sleeve that may occur in the cylinder sleeve mode, has guaranteed the maintain and replace quality of cylinder sleeve of engine.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the working state schematic representation of the utility model on body.

The specific embodiment

As shown in Figure 1, upper and lower movable disk in the

utility model

1,3 and basal disc 2 are three steel disc; Locating ring dish 4 is the steel circular disk, and its diameter of bore is slightly larger than the cylinder sleeve external diameter that needs replacing on the body.At the different-diameter of the cylinder sleeve that uses on the various engines, can make the locating ring dish and the associated components of series, with the cylinder sleeve that forms various models changing device more, the use needs when satisfying different cylinder sleeve of engine and changing.The circumference of four vertical rods 11 along disk evenly distributed, and its two ends are fixedly connected basal disc 2 and locating ring dish 4 respectively, has constituted the pedestal that can fix on engine body 14.On locating ring dish 4, have and the concentric isometrical screw of the screw of engine body cylinder sleeve upper brim,, locating ring dish 4 can be fixed on the engine body by spinning of screw 5.Vertical rod 11 upper sleeve throughs between basal disc 2 and locating ring dish 4 have the connecting rod 10 that 3, two lower ends of following movable disk and following movable disk are joined to pass basal disc 2, and fixedlying connected with the last movable disk 1 on top in its upper end, has constituted an adjustable shelf that can slide up and down on pedestal.

Among Fig. 2, be shaped on a lower convex platform 12 in the bottom surface of following movable disk 4, the lower convex platform bottom surface is shaped on brace.The upper end of pull bar 8 also is shaped on brace.After the brace of pull bar 8 upper ends inserts between two braces on the movable disk 3 bottom surface lower convex platforms down, insert with pin 13 again, pull bar 8 is hung in the bottom center of movable disk 3 down.Be connected with pallet 9 in pull bar 8 lower ends with above-mentioned same way as.Pallet 9 is the disk (shown in Figure 1) that two relative string limits is arranged and have lower convex platform, and the diameter of its lower convex platform is greater than the cylinder sleeve internal diameter.The pallet of this circumference form can successfully be pulled, so that insert the below of cylinder sleeve 15, and is fastened on the mouth of going to the bottom of cylinder sleeve, realizes the operation of pulling out cylinder sleeve on follow-up.The lower convex platform 12 of following movable disk 3 bottom surfaces still presses down the pressing plate of cylinder sleeve, and the diameter of lower convex platform 12 is greater than the external diameter of cylinder sleeve 15 in the body 14 but less than the diameter of bore of locating ring dish 4, so that pass the endoporus of locating ring dish 4, cylinder sleeve is pressed in the body 14 fully.

Among Fig. 1, be provided with the holding screw 16 of stationary links 10 on basal disc 2 sides edge, its effect is when initially installing and fixing this device, utilize this holding screw can carry out the adjustment location of adjustable shelf, the one, be convenient to hanging of pull bar 8 and following movable disk 3, the 2nd, can tentatively adjust the distance between movable disk 1 or following movable disk 3 and the substrate 2, so that place hydraulic jack, be convenient to follow-up cylinder sleeve and extract or push operation at the two.

More on the architecture basics of changing device, as shown in Figure 1, pull bar 8 epimeres are preferably screw rod, and are connected with nut 7 at above-mentioned cylinder sleeve, are welded with in nut 7 outsides to intert the upright ring 17 of pin rod 6.The effect of these parts is set, be to put into before cylinder sleeve and following movable disk 3 hang at pull bar 8, because deal is heavier, will be in the in advance location suitable for reading of cylinder sleeve 15: when nut 7 after pull bar 8 tops are threaded to suitable height, can on the upright ring 17 of nut 7 both sides, insert pin rod 6 respectively, and frame is on locating ring dish 4, can carry out easily then carrying a tray under the pull bar 9 with operation such as hanging of the fastening of cylinder sleeve end opening and pull bar upper end.
