Detailed description of the invention
In order to there be understanding clearly to technical characteristic of the present utility model, object and effect, now contrast accompanying drawing and describe detailed description of the invention of the present utility model in detail.
As shown in Figures 1 and 2, trip fixed axle sleeve withdrawing device in the utility model preferred embodiment comprises two snap fits 20 for the inner hole with the axle sleeve to be removed 10 on stand 10 ', and correspondingly with snap fit 20 connects and provide one along the driving mechanism 30 of the power of axle sleeve 10 axis.The present embodiment is fastened by the endoporus of snap fit 20 with axle sleeve 10, under the power effect of the axis provided at driving mechanism 30, drive axle sleeve 10 to move axially, thus taken out by axle sleeve 10, its structure is simple, ensure that the integrality of axle sleeve, facilitate maintainer to analyze problem, meanwhile, save man-hour, reduce labour intensity, improve operating efficiency.
In certain embodiments, snap fit 20 comprises and the body 21 of the circular arc of the internal face form fit of axle sleeve 10 and the chuck 22 of axially two opposite ends and the boss 23 that are separately positioned on body 21.Chuck 22 is arranged on the extrados of body 21, and boss 23 is arranged on the intrados of body 21, and preferably, boss 23 is arranged along the intrados circumference of body 21.
Further, the radian of body 21 is less than 180 degree, makes two snap fits 20 be spliced into incomplete tubular, forms gap between the two and is convenient to put into together in axle sleeve 10.In other embodiments, the quantity of snap fit 20 also can be more than two.
In certain embodiments, driving mechanism 30 comprises plunger tip 31, shaft coupling 32, guide rod 33, force application apparatus 34 and block 35.Plunger tip 31 is folded between two snap fits 20, and to keep in the annular groove 11 of chuck 22 inlay card on axle sleeve 10 internal face, plunger tip 31 also offsets with boss 23 and coordinates, with in axial location.Plunger tip 31 comprises and the column body segment 311 of the intrados form fit of snap fit 20 and the thread segment 312 of one end being arranged on column body segment 311.The external diameter of column body segment 311 and the intrados internal diameter of snap fit 20 match, to ensure the compactness coordinated between body 21 and column body segment 311.Meanwhile, the height of column body segment 311 is suitable with the height of body 21, and stress deformation when preventing snap fit 20 from working, promotes the intensity of snap fit 20 entirety.
Further, one end end face that column body segment 311 is connected with thread segment 312 offsets with boss 23 and coordinates, and thread segment 312 is corresponding with guide rod 33 to be connected.One end that guide rod 33 is corresponding with thread segment 312 is provided with external screw thread, shaft coupling 32 matches with the external screw thread of thread segment 312 and guide rod 33 respectively, both can ensure that plunger tip 31 was connected with guide rod 33, plunger tip 31 and shaft coupling 32 pairs of boss 23 also can be made to lock, holding position between plunger tip 31, snap fit 20, axle sleeve 10 is allowed to locate, mutual constraint, forms an entirety, facilitates the stressed pull-out of pull bar.In other embodiments, also screwed hole can be set on column body segment 311, allow the external screw thread on guide rod 33 directly be connected with column body segment 311.
Further, thread segment 312, column body segment 311 and guide rod 33 are coaxially arranged, and the axes coincide of the extrados of axis and body 21, when guide rod 33 is stressed, can ensure that the power be applied on axle sleeve 10 can not produce skew in the axial direction, improves the efficiency of taking-up.
Force application apparatus 34 matches with guide rod 33, to provide axial power to guide rod 33.Force application apparatus 34 comprises gravity drop hammer 341, and the middle part of gravity drop hammer 341 is provided with through hole 342, and can be set on guide rod 33 with moving around by through hole 342, block 35 be arranged on the other end of guide rod 33.Preferably, block 35 is dismountable to be arranged on guide rod 33, to be convenient for changing the gravity drop hammer 341 of Different Weight.Meanwhile, also convenient to its replacing when block 35 is damaged.In other embodiments, also gravity drop hammer 341 can be cancelled, allow hydraulic means directly draw guide rod 33, guide rod 33 is exerted a force.
When taking out axle sleeve 10, first snap fit 20 being put in axle sleeve 10, allowing chuck 22 be engaged to annular groove 11 on axle sleeve 10 inwall.Put between two snap fits 20 by plunger tip 31 from chuck 22 one end again, thread segment 312 through boss 23 institute at one end, is connected with guide rod 33 by shaft coupling 32.Now, fixedly form a whole between snap fit 20, plunger tip 31 and axle sleeve 10, radial direction can not be produced between three and rock, ensure that the direction of axial power is not departed from.
Gravity drop hammer 341 cover is set on guide rod 33, then block 35 is installed on the other end of guide rod 33.Allow guide rod 33 vertically place, and block 35 is positioned at lower end.Gravity drop hammer 341 is upwards lifted, then is discharged whereabouts, impact block 35, under the Action of Gravity Field of gravity drop hammer 341, by guide rod 33, plunger tip 31, snap fit 20, power is passed to axle sleeve 10, drive axle sleeve 10 to move down.If it is too tight that axle sleeve 10 is set, then the gravity drop hammer 341 that replaceable weight is larger.
In other embodiments, also can draw-in groove or other connecting portion be set in snap fit 20, drive snap fit 20 to move by connecting rod or other fluid pressure drive devices, axle sleeve 10 is taken out.
Understandably, above-mentioned each technical characteristic can be combined use and unrestricted.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
