The copper sheathing aperture copper scale of different depth, reamer 2 are plugged in the cylinder head bore 5 of cylinder head and contacted with copper sheathing 6, the aperture of its copper sheathing
The distance between cylinder cap aperture of cylinder head distance that as reamer 2 is stretched out outside handle 1, the depth that reamer 2 is inserted in handle 1
Spend smaller, then the distance stretched out in outside handle 1 is bigger, is provided with the joining place of handle 1 and reamer 2 and is sheathed on the periphery of reamer 2
And the elastic clip 3 in handle 1 is plugged in simultaneously, the elastic clip 3 is flexible, when being extruded by external force, is drawn close to centre
Shrink, clamp reamer 2, when external force removes, resilience to the periphery automatically, unclamp reamer 2, be provided with and handle 1 in the periphery of elastic clip 3
It is movably connected so that elastic clip 3 shrinks or the friction top of resilience 4, friction top 4 can be along the axial movement of handle 1, when friction top 4 is past
The direction of handle 1 close to when, realize and deformation retract brought it about to the force of elastic clip 3, so as to clamp reamer 2, when friction top 4 is toward hand
The direction of handle 1 away from when, that is, removed the pressure to elastic clip 3, made its automatic rebounding, so as to unclamp reamer 2, to change difference
The reamer 2 of diameter, escapement a being provided between friction top 4 and elastic clip 3, escapement a can prevent elastic clip 3 from coming off,
When changing reamer 2, due to having frictional force between handle 1, elastic clip 3 and reamer 2 when starting, reamer 2 can be by one
Outside pulling force, elastic clip 3 can then slide in and out, and escapement a can then prevent elastic clip 3 as reamer 2 moves, and avoid
It departs from friction top 4.The utility model is simple in construction, easy to operate, and the copper scale in copper sheathing aperture is removed using reamer 2,
The copper scale in copper sheathing aperture can be thoroughly removed, and the wall of scratch cylinder head bore 5 and copper sheathing 6 can be avoided, greatly reduces labor intensity,
Provide operating efficiency and product quality.
Specifically, being provided with the first tapering 31 of outer narrow inner width in one end of elastic clip 3, accordingly, set in the end of handle 1
The first tapering 31 can be accommodated and bore groove 11 by the first of its crimp by having；The of outer narrow inner width is provided with the other end of elastic clip 3
Two taperings 32, accordingly, the second tapering 32 can be accommodated and bore groove 41 by the second of its crimp by being provided with the one end of friction top 4,
Wherein, the first tapering 31 and the taper of the first cone groove 11 are adapted, and the second tapering 32 and the taper of the second cone groove 41 are adapted, it
Between assembling when be interference fit, assembling when, the second tapering 32 with second bore groove 41 cooperate, make friction top 4
One axial compressive force and a radial pressure are produced to elastic clip 3, so that direction of the elastic clip 3 along handle 1 is moved and along hinge
The direction of knife 2 is shunk to clamp reamer 2, and while elastic clip 3 moves, the first tapering 31 and the first cone phase interworking of groove 11
Close, handle 1 produces a radial pressure to elastic clip 3 shrinks its direction along reamer 2, so as to clamp reamer 2, clamps twice
Mode, substantially increase reamer 2 connection reliability.The utility model is novel in design, and the elasticity of taper is provided with by both ends
Folder 3 is equipped with end bores handle 1, the friction tops 4 of groove and is engaged, and is clamped in reamer 2 is adjustable on handle 1, can basis
The extension elongation of the depth adjustment reamer 2 in copper sheathing aperture, to meet the removal to different depth copper sheathing aperture copper scale, the scope of application
Extensively, it is practical.
Preferably, screwed hole 42 and hand are provided with the other end of friction top 4 to be threadedly coupled between friction top 4 and handle 1
Handle 1 is connected, easy to operation, and maximum of the diameter more than the screwed hole 42 is additionally provided with positioned at the inner side of screwed hole 42 in friction top 4
The resigning chamber 43 of diameter, the resigning chamber 43 are located between the cone groove 41 of screwed hole 42 and second, are an annular chamber, it is therefore an objective to be easy to
The installation of elastic clip 3, to avoid the second tapering 32 of elastic clip 3 and the inner chamber of friction top 4 from interfering, wherein, the present embodiment
In escapement a include clamping boss 44 on the resigning chamber 43 and on elastic clip 3 and can accommodate clamping boss 44
To form the annular slot 33 of engaging, clamping boss 44 is located on the resigning chamber 43 of the second cone groove 41 side, is a horizontal stroke
To be arranged in resigning chamber 43 it is cylindrical on fixture block, its to friction top 4 radial protrusion height by second cone groove 41 it is maximum cylindrical
Track is blocked, and when installing elastic clip 3, one end of the second tapering 32 on elastic clip 3 is directed to the screwed hole 42 of friction top 4, so
Elastic clip 3 is pushed into the inner chamber of friction top 4 along the axis direction of friction top 4 afterwards, because elastic clip 3 carries elasticity, when the second cone
Portion 32 it is maximum it is cylindrical elastic clip 3 shrinks when being contacted with clamping boss 44, the second tapering 32 may pass through clamping boss 44 and with
Second cone groove 41 coordinates, now, the position correspondence of clamping boss 44 and the annular slot 33 of elastic clip 3, due to the elasticity of elastic clip 3
Recover, so that clamping boss 44 enters in annular slot 33 structure for forming engaging, reach the purpose of anticreep, be easy to reamer
The regulation of 2 extension elongations.
Preferably, in above-described embodiment, its handle 1 includes force application rod 12 and the connecting rod 13 perpendicular to the force application rod 12,
Its one end of elastic clip 3 and friction top 4 with connecting rod 13 is connected, and the spiral shell being connected with friction top 4 is provided with the one end of connecting rod 13
Line post 14, the mounting hole 15 of the interior knife bar diameter for being more than reamer 2 provided with diameter of connecting rod 13 on handle 1, accordingly, in bullet
Property folder 3 in be more than provided with diameter reamer 2 knife bar diameters holes for clamping 34, the reamers 2 of different-diameter can be changed, met different
Copper scale requirement is gone in the copper sheathing aperture of diameter cylinder head bore 5, expands the use range of the device.
A kind of method for removing copper bush of fuel injector aperture copper scale, this method is that the copper scale in copper sheathing aperture is entered using reamer 2
Row removes, by designing a kind of device combined by handle 1, elastic clip 3, reamer 2 and friction top 4, first according to copper sheathing
The extension elongation of the depth adjustment reamer 2 in aperture is to be assembled on handle 1；Then reamer 2 is inserted in cylinder head bore 5, made
Its end contacts with copper sheathing aperture；Last rotary handle 1 makes the copper scale in copper sheathing aperture come off, and realizes quick removal copper bush of fuel injector
Aperture copper scale.
Wherein.Reamer 2 is adapted with cylinder head bore 5, the extension elongation of reamer 2 be equal to copper sheathing aperture and cylinder cap aperture away from
From, i.e., coordinate between reamer 2 and cylinder head bore 5 for gap, in order to avoid scratch cylinder head bore 5, during practical application, reamer 2
Diameter should be slightly less than the diameter of cylinder head bore 5, when the end face for screwing lid 4 is bonded with the end face of cylinder head bore 5, then rotary reamer 2, in order to avoid
Scratch copper sheathing 6.
Above-described is only preferred embodiment of the present utility model, it should be pointed out that is come for those skilled in the art
Say, on the premise of the utility model structure is not departed from, several modifications and improvements can also be made, these are all without this reality of influence
With the effect and practical applicability of new implementation.
