Abstract
The utility model discloses a valve oil seal press-fitting tool, and belongs to the field of automobiles. The valve oil seal press-fitting tool comprises a sleeve, a pressing rod and a handle, the handle is vertically fixed to one end of the pressing rod, the sleeve is fixed to the other end of the pressing rod, a blind hole is formed in the sleeve in the axial direction, a through hole is formed in one end of the blind hole, the pressing rod penetrates through the through hole to be fixed, the diameter of the top end of the pressing rod is matched with a valve guide pipe, and the depth of a cavity between the blind hole and the pressing rod is matched with the height between the valve guide pipe and an oil seal mounting position. Through the structure, the valve oil seal press-fitting tool is simple in structure, low in cost and convenient to operate, an oil seal can be mounted in place well and cannot be deformed or abraded, the pressure is proper, and compressional deformation cannot happen to the oil seal.
Description
Technical field
The utility model relates to a kind of press mounting tool, particularly a kind of valve oil seal press mounting tool, and it belongs to automotive field.
Background technology
The assembling of valve oil seal is important by all means to engine, valve oil seal volume is little, and assembly space is can operating space narrow and small, very difficult assembling, iff installing by manual auxiliary conventional instrument, very trouble like this operates, meanwhile, oil tight skeleton is out of shape in the process of installing and easily, thereby produces wearing and tearing and trimming, so just reduce the sealing of valve oil seal, thereby can not realize in good condition the water-oil separating of engine.Therefore need a kind of special valve oil seal erecting tools, can guarantee that oil sealing can make valve oil seal and valve guide rod coaxial in installation process, and can guarantee that the pressure press-fiting is suitable, do not make framework deformation wearing and tearing.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple in structure, easy to operate and can guarantee the coaxial mounted valve oil seal press mounting tool of valve oil seal.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: this one valve oil seal press mounting tool, comprise sleeve, depression bar and handle, and it is characterized in that:
Described handle is vertically fixed on one end of depression bar, and sleeve is fixed on the other end of depression bar;
One end of described sleeve has blind hole along axis direction, and described sleeve has the through hole mating with depression bar in the middle of closed one end of blind hole, and one end of described depression bar is through through hole and fixing; Between described blind hole and depression bar, leave cavity, and the degree of depth of cavity and valve guide bushing are to the matched of oil sealing installation site; Described depression bar mates through the diameter of one end and the internal diameter of vent pipe of through hole.
Further, in described through hole, have gathering sill, depression bar is provided with through hole connecting portion the raised line mating with gathering sill.
Further, the connected mode between described sleeve and depression bar is that interference is connected.
The utility model compared with prior art, has the following advantages and effect: valve oil seal press mounting tool is simple in structure, and cost of manufacture is cheap; Use easy to operately, and can guarantee that valve oil seal keeps coaxial with valve guide rod when installing, and has avoided like this oil sealing unbalance stress distortion and has worn and torn; The degree of depth of cavity and valve guide bushing be to the matched of oil sealing installation site, and oil sealing needs the position of installing being just pressed onto when press-fiting like this, avoided pressure too small closely or pressure excessive and by oil sealing crimp.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is cutaway view of the present utility model.
Fig. 3 is side view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and by embodiment, the utility model is described in further detail, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
As shown in Figure 1, valve oil seal press mounting tool of the present utility model comprises sleeve 1, depression bar 2 and handle 3, and handle 3 is vertically fixed on one end of depression bar 2, and sleeve 1 is fixed on the other end of depression bar 2.One end of sleeve 1 has blind hole 4 along axis direction, and sleeve 1 has the through hole 5 mating with depression bar in the middle of closed one end of blind hole 4, and one end of depression bar 2 is through through hole 5 and fixing.Between blind hole 4 and depression bar 2, leave cavity 6, and the degree of depth of cavity 6 and valve guide bushing are to the matched of oil sealing installation site.Depression bar 2 mates through the diameter of one end and the internal diameter of vent pipe of through hole 5.
As shown in Figure 3, have gathering sill 7 in through hole 5, depression bar 2 is provided with through hole 5 connecting portions the raised line 8 mating with gathering sill.Connected mode between sleeve 1 and depression bar 2 is that interference is connected, and heating muff 1 makes through hole 5 be subject to thermal change large, then by gathering sill 7, is mated sleeve 1 is arranged on depression bar 2 with raised line 8, and cooling rear through hole 5 shrinks, and sleeve 1 is fixed on depression bar 2 like this.
Adopt such technical scheme, the valve oil seal press mounting tool of the present embodiment when in use, valve oil seal is placed in the cavity 6 of valve oil seal press mounting tool, then valve guide bushing being aimed in depression bar 2 tops inserts, like this by the guiding on depression bar 2 tops, the valve oil seal that makes to be positioned at cavity 6 is coaxial with valve guide rod all the time, install like this and needn't worry that oil sealing produces deformation and wearing and tearing because of discontinuity, simultaneously because the degree of depth of cavity 6 and valve guide bushing are to the matched of oil sealing installation site, like this when valve oil seal is installed in place, valve guide rod coordinates spacing with cavity 6 bottoms, guaranteed can not continue extruding, place senior general's oil sealing crimp of exerting oneself.
The utility model is simple in structure, and cost of manufacture is cheap; Use easy to operately, and can guarantee that valve oil seal keeps coaxial with valve guide rod when installing, and has avoided like this oil sealing unbalance stress distortion and has worn and torn; The degree of depth of cavity and valve guide bushing be to the matched of oil sealing installation site, and oil sealing needs the position of installing being just pressed onto when press-fiting like this, avoided pressure too small closely or pressure excessive and by oil sealing crimp.
Above content described in this description is only to the explanation of the utility model example.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment; only otherwise depart from the content of the utility model description or surmount this scope as defined in the claims, all should belong to protection domain of the present utility model.
