Abstract
The utility model discloses a fuel injector detaching device, and particularly relates to a fuel injector detaching puller. The fuel injector detaching puller comprises a puller body, a screw stem connected with the puller body, a support frame and a tightening nut, a round hole is arranged at the top end of the support frame, the screw stem is connected with the tightening nut after penetrating out of the round hole, and the puller body is provided with a threaded hole used for being connected with a fuel injector. The fuel injector detaching puller has the advantages that (1), the fuel injector detaching puller mainly consists of the puller body, the screw stem, the support frame and the tightening nut and is simple in structure, and (2), the fuel injector can be detached without detaching parts such as an engine hood, an exhaust pipe, an air filter element assembly, an air inlet pipe elbow and the like, and accordingly is convenient in use.
Description
Technical field
The utility model relates to a kind of fuel injector provision for disengagement, particularly a kind of fuel injector dismounting chest expander.
Background technology
In the correction work of being engaged in high-pressure pump and fuel injector, often run into fuel injector and tear a difficult problem of not getting off open, especially before dismounting oversize vehicle 6135 diesel engines series fuel injector, need to dismantle a lot of engine fittings.As tear open and start the alert lid of power traction, blast pipe, the air filtering core assembly, many parts such as air inlet pipe elbow, generally all adopt conventional approach such as prizing firmly during dismounting with the bobsled rod, run into get rusty motionless just with oil vacuole, tup shake, as easy as rolling off a log damage fuel injector and cylinder cap, manpower, financial resources and the time of waste greatly.
Summary of the invention
Problem to be solved in the utility model is: a kind of fuel injector simple in structure, easy to use dismounting chest expander is provided.
In order to solve the problems of the technologies described above, fuel injector dismounting chest expander of the present utility model, comprise pulling force body, the screw rod, bracing frame and the tightening nut that link to each other with the pulling force body, the top of support frame as described above is provided with a circular hole, described screw rod passes the back and links to each other with tightening nut from circular hole, described pulling force body is provided with the screwed hole that is connected usefulness with fuel injector.
For with pulling force body and firm being fixed together of screw rod, fuel injector dismounting chest expander of the present utility model is provided with the clamp nut of fastening usefulness between described screw rod and the pulling force body.
In order to reduce the wearing and tearing to bracing frame, fuel injector dismounting chest expander of the present utility model is provided with packing ring between the circular hole on described tightening nut and the bracing frame.
For economical with materials, fuel injector dismounting chest expander of the present utility model, support frame as described above is provided with three dead slots.
The beneficial effect that the utility model is obtained is: (1) mainly is made up of pulling force body, screw rod, bracing frame and tightening nut, and is simple in structure; (2) do not need dismounting to start numerous parts such as the alert lid of power traction, blast pipe, air filtering core assembly, air inlet pipe elbow the fuel injector dismounting can be finished, thus easy to use.

Fig. 1 is a front view of the present utility model.
Fig. 2 is a left view of the present utility model.
Among the figure: 1, screwed hole, 2, the pulling force body, 3, clamp nut, 4, dead slot, 5, screw rod, 6, bracing frame, 7, circular hole, 8, packing ring, 9, tightening nut.
The specific embodiment
As depicted in figs. 1 and 2, fuel injector dismounting chest expander of the present utility model, comprise pulling force body 2, the screw rod 5 that links to each other with pulling force body 2, bracing frame 6 and tightening nut 9, the top of support frame as described above 6 is provided with a circular hole 7, described screw rod 5 passes the back and links to each other with tightening nut 9 from circular hole 7, described pulling force body 2 is provided with the screwed hole 1 that is connected usefulness with fuel injector; Be provided with the clamp nut 3 of fastening usefulness between described screw rod 5 and the pulling force body 2; Be provided with packing ring 8 between the circular hole 7 on described tightening nut 9 and the bracing frame 6; Support frame as described above 6 is provided with three dead slots 4.
In the time of concrete the use, bracing frame 6 is put on the cylinder cap, rotary screw 5 and pulling force body 2, make the screwed hole 1 of pulling force body 2 front ends be fixed together with atomizer, then with spanner rotation tightening nut 9, under the effect of tightening nut 9, screw rod 5 rises gradually, thereby drive pulling force body 2 atomizer is disassembled.
Fuel injector dismounting chest expander of the present utility model mainly is made up of pulling force body 2, screw rod 5, bracing frame 6 and tightening nut 9, thereby simple in structure; Simultaneously, owing to do not need dismounting to start numerous parts such as the alert lid of power traction, blast pipe, air filtering core assembly, air inlet pipe elbow the fuel injector dismounting can be finished, thereby easy to use.
