Abstract
The utility model discloses a fuel injector disassembly tool, which comprises a pull rod, a movable piece, a double-headed stud and a connecting piece, wherein the movable piece is provided with a through hole; the movable piece is sheathed on and slides along the pull rod; the pull rod, the double-headed stud and the connecting piece are connected in sequence; a thread slot matched with the external threads of the fuel injector is arranged at the end of the connecting piece. The fuel injector disassembly tool has the advantages of convenient disassembly, prevention of damage to parts, low cost and wide application range.
Description
Technical field
The utility model relates to a kind of dismounting frock, relates in particular to a kind of oil sprayer dismounting frock.
Background technique
At present, it is to adopt pressing plate to be pressed on the cylinder head upper type that many diesel injectors are connected with motor, when product development and maintenance service owing to reason such as length, carbon distribution service time, oil sprayer is connected with cylinder cap closely, often by using conventional means to dismantle, and dismantle even have the hidden danger of part of damage by force.Therefore, need to occur a kind of oil sprayer that can solve and dismantle the difficult technologies problem, and safe and efficient, save time oil sprayer dismounting frock with low cost.
Summary of the invention
Technical problem to be solved in the utility model is the defective that overcomes prior art, a kind of convenient disassembly is provided, avoids damage parts and oil sprayer dismounting frock with low cost.
For solving the problems of the technologies described above, the utility model provides a kind of oil sprayer dismounting frock, comprise pull bar, movable part, stud and coupling, described movable part is provided with through hole, described movable part is sleeved on the described pull bar, and along described pull bar slip, described pull bar, stud and coupling are linked in sequence, and the end of described coupling is provided with the thread groove that is complementary with the oil sprayer outside thread.
The end of described pull bar is provided with outstanding spacing flange.
Connecting end at described pull bar and described stud is provided with the scyewed joint groove that is complementary with described stud, and described pull bar is threaded with described stud one side; Described stud opposite side is threaded with described coupling.
Owing to adopt above-mentioned technological scheme, the utlity model has following beneficial effect:
1, simple in structure, material and processing cost are low;
2, be easy to move, can be used for different workplaces;
3, easy to use, safe and effective, can prevent to damage component and motor;
4, save time.

Fig. 2 is the sectional view of pull bar of the present utility model and movable part;
Fig. 3 is the structural representation of I part among Fig. 2;
Fig. 4 is the sectional view of coupling of the present utility model.
Wherein: the 1-pull bar; The 2-movable part; The 3-stud; The 4-coupling; The spacing flange of 5-; The 6-connection slot; The 7-thread groove.
Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figures 1 to 4, the utility model oil sprayer dismounting frock, comprise movable part 1, pull bar 2, stud 3 and coupling 4, the central authorities of movable part 1 are provided with through hole, movable part 1 is sleeved on the pull bar 2, and along pull bar 2 slips, the end of pull bar 2 is provided with outstanding spacing flange 5, plays the effect of restraint spare 1 activity.Pull bar 2, stud 3 and coupling 4 are linked in sequence, and the end of coupling 4 is provided with the thread groove 7 that is complementary with the oil sprayer outside thread.
Connecting end at pull bar 2 and stud 3 is provided with the scyewed joint groove 6 that is complementary with stud 3, and pull bar 2 is threaded by this scyewed joint groove 6 with stud 3 one sides.The opposite side of stud 3 is threaded with coupling 4.
During use, the thread groove of pull bar 2 links to each other with standard dual head double-screw bolt 3.According on the oil sprayer with coupling that is complementary with it 4 of specification manufacturing of high-pressure oil pipe connecting thread, coupling 4 is provided with the double thread screw groove, the one head links to each other with standard dual head double-screw bolt 3, the other end links to each other with the oil sprayer outside thread.When the dismounting oil sprayer, turn on the high-pressure oil pipe on the oil sprayer earlier, the oil sprayer outside thread is screwed into coupling 4, re-use the thread groove that the standard dual head double-screw bolt is screwed into the coupling the other end, then the pull bar that puts movable part is connected with the standard dual head double-screw bolt, firmly movable part is moved toward spacing flange 5 directions of pull bar, movable block in the extremely short time will produce very big impact force according to momentum and theorem of impulse, thereby oil sprayer is drawn back from motor.
As Fig. 1, movable part 2 of the present utility model is enclosed within on the pull bar 1, and coupling 4 links to each other with oil sprayer, movable part 2 is fast moving in pull bar 1, the spacing flange 5 of bump pull bar 1 produces impact force, transmits pulling force to coupling 4 by pull bar 1, thereby oil sprayer is pulled from motor.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technological scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technological scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
