Abstract
The utility model discloses a steyr engine fuel injector remover, which aims to overcome the defects when maintaining a fuel injector of an existing steyr engine that because the fuel injector is adhered with a water jacket inner hole, the fuel injector and the water jacket inner hole can be dismounted through dismounting a cylinder cover, thereby wasting time, labor and cylinder pads, and the efficiency is low. The lower end of a vertical pull rod is fixed with a nut which can be screwed on a lead screw on the top portion of the fuel injection, a casing support is arranged above the nut, is arranged on the top surface of the cylinder cover of the engine and is sleeved on the outer portion of the circumference of the fuel injector, the support pad is arranged on the casing support, and a nut is closely close to the support pad to be screwed on a screw rod on the upper end of the pull rod. Because the steyr engine fuel injector remover can be directly connected with the fuel injector, and can press a water jacket on the outer portion of the fuel injector through the casing support, the fuel injector can be pulled out from the water jacket just needing one person to screw the nut, thereby not damaging the cylinder pad and the water jacket, saving time and labor, saving manpower source, and having high dismounting efficiency. Compared with the prior art, the steyr engine fuel injector remover greatly increases the work efficiency, and saves materials.
Description
Technical field
The utility model belongs to instrument, specifically a kind of specific purpose tool of dismantling the steyr engine fuel injector.
Background technology
The engine that large-scale truck is used, generally use 8000-10000 hour after, problem in various degree will appear, arrived certain service time, to safeguard and adjust according to the rules.Steyr engine for example after being installed in fuel injector on the cylinder head and using certain time limit, situations such as atomization badness can occur, directly has influence on the operate as normal of engine, therefore fuel injector must be disassembled from cylinder cap to repair or replace.
Because transport task fuel injector heavy and that engine is worked together is busy with one's work, shell forms carbon deposit easily, and frequent and water jacket endoporus bonds very tightly, can't directly pull out above cylinder cap with general method at all.Will connect water jacket and take out of together if extract by force, engine cooling water will enter cylinder like this, fragile again water jacket of while.Result of the above problems can only be that water is bled off at present, pulls down cylinder cap, strikes throwing from the negative, and this way is time-consuming, effort, and cylinder cap pulls down back cylinder pad and just be done for, and dismounting once will be changed a cylinder pad and cause waste; Simultaneously, with 6 fuel injectors of said method dismounting, need 2 people just can finish in 4 hours, operating efficiency is low.
The utility model content
Technical problem to be solved in the utility model is, overcome the fuel injector of existing maintenance steyr engine, because of fuel injector and the adhesion of water jacket endoporus, pulling down cylinder cap could dismantle, time-consuming, effort, and the shortcoming of wasting cylinder pad, inefficiency, a kind of steyr engine fuel injector extracting tool is provided.
In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: in the lower end of erectting pull bar, be fixed with the screw that can be screwed on the screw mandrel of steyr engine fuel injector top, more than the screw of the pull bar body of rod, be positioned at the end face of engine cylinder cover, lay and can be enclosed within the outer bush support of fuel injector circumference, supporting pad is sitting on the bush support, and nut is screwed on the screw rod of pull bar upper end near supporting pad.
The utility model also has following technical characterictic:
Described bush support can be stacked together a plurality of.
During use, the nut of pull bar lower end is screwed on the engine fuel injector screw mandrel, pull bar and fuel injector are linked together; Then bush support is enclosed within outside the body of rod of pull bar, its lower end is sitting in above the cylinder cap of steyr engine, is positioned on the water jacket of fuel injector outside, supporting pad is overlayed on the bush support again, at last nut is screwed on the screw rod of pull bar upper end, turning nut can pull out fuel injector.
Advantage of the present utility model and good effect are, because above-mentioned instrument can directly be connected with fuel injector, and can utilize bush support to push down the water jacket of fuel injector outside, only need 1 people to turn nut then, the cylinder cap of fuel injector from engine can be pulled out, half an hour, can be finished the dismounting of 6 fuel injectors, need not dismantle cylinder cap, just do not damage cylinder pad and water jacket yet, compared with prior art, improved work efficiency greatly, save time, laborsaving, saved human resources, the removal efficiency height has been saved parts and material.Above-mentioned tool construction is simple, makes easily, and is with low cost, easy to use, is easy to apply.
Description of drawings
Fig. 1 is a cutaway view of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Among Fig. 1, the lower end erectting pull bar 3 is fixed with the screw 6 that can be screwed on the steyr engine fuel injector top screw mandrel 7, and the body of rod of pull bar 3 is at screw more than 6; Be positioned at the end face of engine cylinder cover 8, lay and to be enclosed within the outer bush support 4 of fuel injector circumference.If too short because of a bush support 4, can not once fuel injector be extracted, can also back out nut 1, take out supporting pad 2, in described bush support 4 bottoms, stack another bush support 5 again, also can upwards stack many continuously.Supporting pad 2 is sitting on the bush support 4, and nut 1 is screwed on the screw rod 3.1 of pull bar 4 upper ends near supporting pad 2.
During use, the nut 6 that pull bar 3 lower ends are fixing is screwed on the engine fuel injector screw mandrel 7, and pull bar 3 and fuel injector are linked together; Then bush support 4 or bush support 4 and 5 are stacked outside the body of rod that is enclosed within pull bar 3, its lower end is sitting in above the cylinder cap 8 of steyr engine, is positioned on the water jacket of fuel injector outside, push down the water jacket of fuel injector outside with bush support 4 or 5, again supporting pad 2 is placed on the bush support 4, at last nut 1 is screwed on the screw rod 3.1 of pull bar 3 upper ends, turn nut 1 pull bar 3 by on carry, pull bar 3 can be pulled out fuel injector by the fixing nut 6 in its lower end.
Claims (2)
1. steyr engine fuel injector extracting tool, it is characterized in that: in the lower end of erectting pull bar, be fixed with the screw that can be screwed on the screw mandrel of steyr engine fuel injector top, more than the screw of the pull bar body of rod, be positioned at the end face of engine cylinder cover, lay and can be enclosed within the outer bush support of fuel injector circumference, supporting pad is sitting on the bush support, and nut is screwed on the screw rod of pull bar upper end near supporting pad.
