Description
Technical field
The utility model relates to the dismantling device of a kind of engine fuel injector water proof cover.
Background technology
The Main Function of engine fuel injector water proof cover prevents the cooling fluid in engine cylinder cap from entering in cylinder, if drainage appears in fuel injector, this cover must be taken out during upkeep operation, changes water proof cover assembly.
When the dismounting operation of water proof cover, overlap the impact of multiple valve spring of circumferential distribution by working space and water proof, general drawbench cannot use; Owing to not having water proof to overlap special dismantling device, cylinder head assembly need be pulled down from engine, then adopt from cylinder head bottom surface the mode of knocking pounded out by water proof cover and knock in cylinder head, thus complete the dismounting of water proof cover.Due to the restriction by working space, the disassemble and assemble work amount of cylinder head is comparatively large, improves cycle and the labour intensity of upkeep operation, reduces operating efficiency.
Summary of the invention
Technical problem to be solved in the utility model is to provide the dismantling device of a kind of engine fuel injector water proof cover, this dismantling device overcomes the defect of traditional water proof cover dismounting, avoid the dismounting of cylinder head assembly, fast, conveniently can implement the dismounting that water proof overlaps, reduce the labour intensity of water proof cover dismounting, improve dismounting operating efficiency.
For solving the problems of the technologies described above, the dismantling device of the utility model engine fuel injector water proof cover comprises dismounting post, ratchet support set, screw rod, top cover, locking nut and dismounting nut, described dismounting capital end is provided with screw, bottom is provided with external screw thread, described screw rod twists the screw in described dismounting capital end, described locking nut is twisted in described screw rod and fastening screw and dismounting post, described ratchet support set is inserted in described screw rod, described top cap central is provided with through hole and is inserted in described screw rod and is positioned at described ratchet support set top, described dismounting nut is twisted in described screw rod and is positioned at the end face of described top cover.
Further, this dismantling device also comprises pad, and described pad is inserted in described screw rod and between described top cover and dismounting nut.
Further, described ratchet support set bottom four ratchets uniformly at intervals.
Because the dismantling device of the utility model engine fuel injector water proof cover have employed technique scheme, namely this dismantling device comprises dismounting post, ratchet support set, screw rod, top cover, locking nut and dismounting nut, described dismounting capital end is provided with screw, bottom is provided with external screw thread, described screw rod twists the screw in described dismounting capital end, described locking nut is twisted in described screw rod and fastening screw and dismounting post, described ratchet support set is inserted in described screw rod, described top cap central is provided with through hole and is inserted in described screw rod and is positioned at described ratchet support set top, described dismounting nut is twisted in described screw rod and is positioned at the end face of described top cover.This dismantling device overcomes the defect of traditional water proof cover dismounting, avoids the dismounting of cylinder head assembly, fast, conveniently can implement the dismounting that water proof overlaps, reduce the labour intensity of water proof cover dismounting, improve dismounting operating efficiency.

Below in conjunction with drawings and embodiments, the utility model is described in further detail:
Fig. 1 is the dismantling device schematic diagram of the utility model engine fuel injector water proof cover;
Fig. 2 is ratchet support set schematic diagram in this dismantling device;
Fig. 3 is the upward view of Fig. 2;
Fig. 4 is the schematic diagram adopting this tool ejector water proof cover.
Detailed description of the invention
As shown in Figure 1, the dismantling device of the utility model engine fuel injector water proof cover comprises dismounting post 7, ratchet support set 1, screw rod 5, top cover 2, locking nut 6 and dismounting nut 4, described dismounting post 7 top is provided with screw, bottom is provided with external screw thread 71, described screw rod 5 twists the screw in described dismounting post 7 top, described locking nut 6 is twisted in described screw rod 5 and fastening screw 5 and dismounting post 7, described ratchet support set 1 is inserted in described screw rod 5, described top cover 2 center is provided with through hole and is inserted in described screw rod 5 and is positioned at described ratchet support set 1 top, described dismounting nut 4 is twisted in described screw rod 5 and is positioned at the end face of described top cover 2.
Further, this dismantling device also comprises pad 3, and described pad 3 is inserted in described screw rod 5 and between described top cover 2 and dismounting nut 4.Pad plays the effect of evenly exerting pressure to top cover, avoids top cover local pressure, guarantees that screw rod turns process vertically movement at dismounting nut, makes dismounting post can extract water proof cover smoothly.
As shown in Figures 2 and 3, further, described ratchet support set 1 bottom four ratchets 12 uniformly at intervals.The top of ratchet support set 1 is annulus 11, bottom jacket wall hollow out forms ratchet 12 spaced apart, when the dismounting operation of water proof cover, space between adjacent ratchet just in time embeds the valve spring of water proof cover periphery, avoids water proof to overlap the interference of dismounting operation process dismantling device and valve spring.
As shown in Figure 4, during the field-strip of water proof cover, the external screw thread of dismounting post 7 bottom is screwed in the screw of water proof cover 8, ratchet support set 1 be inserted in screw rod 5 and bottom against cylinder head 9 plane, the adjacent ratchet gap of ratchet support set 1 embeds the valve spring 10 that water proof overlaps 8 peripheries, thus make this instrument can avoid the interference of valve spring 10, top cover 2 and dismounting nut 4 are installed, now buttress ratchet support set 1 on the other hand, another hand getting spanner turns dismounting nut 4, screw rod 5 under the effect of dismounting nut 4 on move, until dismounting nut 4 turns feel disheartened suddenly, water proof cover 8 is extracted from cylinder head 9 by dismounting post 7 by screw rod 5, complete the dismounting of water proof cover 8.When water proof cover installation exercise, water proof cover 8 twisted the external screw thread in dismounting post 7 bottom and aimed at the installing hole of cylinder head 9, dismounting nut 4 is backed out from screw rod 5, then adopting mallet to knock the top of screw rod 5, until strike motionless, the installation of water proof cover 8 can be completed.
This tool construction is simple, easy to make, it utilizes the gap between the adjacent ratchet of ratchet support set to embed the valve spring of water proof cover periphery, thus solve adopt general drawbench cannot be in place problem, can water proof cover small space in implement dismounting operation, in conjunction with the acting in conjunction of dismounting post, screw rod and dismounting nut, complete the dismounting of water proof cover, thus the dismounting of water proof cover just can be completed without the need to dismantling cylinder head, reduce labour intensity, improve dismounting operating efficiency.
