Abstract
The utility model discloses a fuel injector disassembling device. The fuel injector disassembling device can effectively disassemble a PT fuel injector on an engine and comprises a drawbar, a fastening sleeve, a positioning sleeve and a hammer. The lower end of the drawbar is provided with a pulling head, the upper end of the drawbar is provided with a screw matched with a nut, and the middle of the drawbar is slidingly matched with the hammer; the fastening sleeve is composed of two semi-circular bodies which are in butt joint, the inner wall of the lower end of the fastening sleeve is provided with a ring groove matched with the ring-shaped boss at the upper end of the fuel injector, and the inner side of the upper end of the fastening sleeve is provided with a ring-shaped boss matched with the ring groove formed in the outer wall of the pulling head; the inner hole of the positioning sleeve is matched with the outer circumference of the fastening sleeve. The fuel injector disassembling device can conveniently disassemble the PT fuel injector and has the advantages of being simple in structure, high in practicality, good in usage effects and the like.
Description
Technical field
The utility model relates to a kind of fuel injector detaching device, especially relates to the provision for disengagement of comings N-type and K h type engine h PT fuel injector.
Background technology
When the PT fuel injector of comings N-type and K h type engine h is overhauled, need first fuel injector to be taken apart from engine, because the shell Shang You tri-road O-ring seals of fuel injector and the interior wall pressure in its hole must be tighter, if want, by free-hand, grasp the annular boss that fuel injector is exposed on the outside and pull out outward and cannot pull out, therefore maintenance personal prizes and dials with instruments such as ripping bars, do like this time and effort consuming, careless manipulation can damage fuel injector, when serious, even causes fuel injector to scrap.
Summary of the invention
The purpose of this utility model is just to provide a kind of fuel injector detaching device, and it can effectively dismantle the provision for disengagement of PT fuel injector.
The technical scheme that the utility model adopts is: a kind of fuel injector detaching device, this fuel injector detaching device comprises pull bar, cutting ferrule, positioning sleeve and block stamp, the lower end of described pull bar is provided with pull head, and upper end is provided with and is used in conjunction with nut is screw, and middle part and described block stamp are slidably matched; Described cutting ferrule is two involutory semicircular body, and its lower end inwall is provided with the annular groove that the annular boss with fuel injector upper end is used in conjunction with, inner side, upper end be provided with described pull head outer wall on the annular boss that is used in conjunction with of annular groove; The endoporus of described positioning sleeve and the cylindrical of described cutting ferrule are used in conjunction with.
The utility model can easily be dismantled PT fuel injector, have simple in structure, practical, the feature such as result of use is good.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is that the utility model is used status architecture schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further.
As shown in Figure 1, a kind of fuel injector detaching device of the utility model, this fuel injector detaching device comprises pull bar 10, cutting ferrule 20, positioning sleeve 30 and block stamp 40, the lower end of described pull bar 10 is provided with pull head 11, upper end is provided with and is used in conjunction with nut 12 is screw, and middle part and described block stamp 40 are slidably matched; Described cutting ferrule 20 is two involutory semicircular body, and its lower end inwall is provided with the annular boss 51(of fuel injector 50 upper ends sees Fig. 2) annular groove 21 that is used in conjunction with, inner side, upper end be provided with described pull head 11 outer walls on the annular boss 22 that is used in conjunction with of annular groove; The cylindrical of the endoporus of described positioning sleeve 30 and described cutting ferrule 20 is used in conjunction with.
As shown in Fig. 2, during use, the annular boss 51 and the pull head 11 that first with described two involutory semicircular body cutting ferrules 20, fuel injector 50 are exposed block simultaneously, afterwards positioning sleeve 30 is enclosed within on the cylindrical of cutting ferrule 20 and fixes two semicircular body, then on pull bar 10, be inserted in block stamp 40 nut 12 of screwing on, holding afterwards block stamp 40 moves up and down and impacts nut 12, now impulsive force pulls pull bar 10 by nut 12, and pull bar 10 can be fuel injector 50 from engine stripping out by pull head 11 drive cutting ferrules 20.
