Abstract
The utility model discloses a valve oil seal tool comprising a guide rod and a pressing tool, wherein the guide rod is a cylindrical long rod and divided into a fixing part and a guiding part, the outside diameter of the fixing part is greater than that of the guiding part, and the pressing tool is a device provided with two layers of hole steps. The tool has simple design, and is convenient for production and manual assembly and automatic assembly of equipment, thus leading the installation of a valve oil seal to be fast and convenient and avoiding the problems of improper and deflected installation, smash, and the like of the valve oil seal.
Description
Technical field
The utility model belongs to the engine design field, specifically, relates to the design that a kind of valve oil seal is installed frock.
Background technology
Because automotive performance constantly promotes, cylinder pressure requires more and more higher, and the temperature of valve stem and linear velocity all have big lifting, in this case, require the sealing of valve oil seal, wearability, and high temperature resistance needs big raising before.Valve oil seal is current to have a large amount in variety, as simple mouthful, and the lips mouth structure, the latter is more harsh in matching requirements.At present during the assembling valve oil seal, the operator is positioned over valve oil seal on the valve guide bushing, manual then be pressed into by or be positioned on the install machinery and press-fit, in assembling process, be prone to valve oil seal and install not in placely, dress situation such as smashes partially.
The utility model content
The technical problems to be solved in the utility model is to realize a kind of frock that can convenient reliable assembling valve oil seal.
To achieve these goals, the technical solution adopted in the utility model is: a kind of valve oil seal frock comprises guide post and is pressed into frock, described guide post is the cylinder stock and is divided into fixed part and guide portion, wherein the external diameter of fixed part is greater than guide portion, and the described frock that is pressed into is the device that is provided with rank, two-layer hole.
Described guide portion is made up of the multilayer coaxial clyinder that stretches out from fixed part and its external diameter reduces gradually.
Described guide portion is the cone from fixed part stretches out and external diameter reduces gradually.
The described frock that is pressed into is the cylinder stock.
Described guide post fixed part external diameter is identical with the valve guide bushing internal diameter, and the described outer internal diameter that is pressed into rank, the two-layer hole of frock is slightly larger than the maximum outside diameter of valve oil seal, and the internal layer internal diameter on its rank, two-layer hole is slightly larger than the lip external diameter of valve oil seal.
Advantage of the present utility model is this frock simplicity of design, and is easy to make, and the automatic assembling function of the hand assembled/equipment of being convenient to makes the quick for installation of valve oil seal, and stopped valve oil seal and installed not in placely, and dress situation such as smashes partially.
Description of drawings
Below the content of each width of cloth accompanying drawing expression of the utility model specification and the mark among the figure are briefly explained:
Fig. 1 is the scheme of installation of valve oil seal on cylinder cap;
Fig. 2 is a guide post structural representation shown in Figure 1;
Fig. 3 is the frock partial structurtes schematic diagram that is pressed into shown in Figure 1;
Fig. 4 is a valve oil seal frock operating process schematic diagram;
Mark among the above-mentioned figure is: 1, be pressed into frock; 2, guide post; 3, valve oil seal; 4, valve guide bushing; 5, spring shim; 6, cylinder head; 7, fixed part; 8, guide portion.
The specific embodiment
Valve oil seal tool structure schematic diagram as Figure 1-3 as can be known, this frock comprises guide post 2 and is pressed into frock 1, wherein guide post 2 is the cylinder stock and is divided into fixed part 7 and guide portion 8, and the external diameter of fixed part 7 needs greater than guide portion 8, valve oil seal 3 just can be inserted in guide post 2 very easily and be placed on the valve guide bushing 4 like this, can be designed to multilayer coaxial clyinder for guide portion 8 from fixed part 7 stretches out and its external diameter reduces gradually, perhaps from the cone that fixed part 7 stretches out and external diameter reduces gradually, every design that can conveniently import valve oil seal 3 is all passable; The frock 1 that is pressed in the valve oil seal frock is the cylinder stock that an end is provided with rank, two-layer hole.
Because the dimensions of valve oil seal 3 is a lot, but the oil sealing of various different sizes, its frock need design according to structure of the present utility model.In view of the special construction of valve oil seal 3, when being pressed into valve oil seal 3, need guarantee the positional accuracy that valve oil seal 3 is installed, need the requirement on some structures, the size.
The size of guide post 2 need be decided according to valve guide bushing 4 diameter of bores and valve oil seal 3 lip sizes, guide post 2 fixed parts 7 external diameters and valve guide bushing 4 internal diameters identical (matched in clearance) that need to install valve oil seal 3, the surface accuracy of guide post 2 needs to guarantee, guide post 2 surfaces must not jagged overlap, the processing roughness is below Rz6.3, if press-fit by hand purely, when assembling, can not use this guide post 2, if employing equipment press-fits, this guide post 2 must use so, and the initial position of valve oil seal 3 is guaranteed.
The outer internal diameter that is pressed into the rank, two-layer hole of frock 1 is slightly larger than the maximum outside diameter of valve oil seal 3, and the internal layer internal diameter on its rank, two-layer hole is slightly larger than the lip external diameter of valve oil seal 3.The rigging position that concrete valve oil seal 3 requires is after having assembled, need valve oil seal 3 and valve guide bushing 4 that the gap of 0.5mm is arranged, need be pressed into the outer height dimension h=H+0.5+2.4+0.2 in rank, hole of frock 1, if being pressed into frock 15 of spring pads direct and on the cylinder cover 6 contacts, make that spacer thickness is t, then h=H+0.5+2.4+0.2-t.(wherein: H is the extension elongation of valve guide bushing upper surface to cylinder cap, and 0.5 is the minimum clearance value of oil sealing and conduit, and 2.4 is oil tight skeleton height cited herein, and 0.2 is the cumulative limit value).So being pressed into the size of frock 1 also is to formulate according to the specification of valve oil seal.The assurance of the accurate position of valve oil seal 3 is to guarantee by this press-fitting tool 1 size own fully, so when doing this frock, size h must control well.
Valve oil seal frock operating process schematic diagram as shown in Figure 4 as can be known, this frock at first is coated with a little lubricating oil on the surface of guide post 2 in use, then guide post 2 is inserted in the valve guide bushing 4, should be noted that its direction places guide portion 8 outside the valve guide bushing 4 when inserting guide post 2; Again with valve oil seal 3 on guide post 2 is packed valve guide bushing 4 into, place to rectify; Take out guide post 2 afterwards, will be pressed into frock 1 and be sleeved on the valve oil seal 3, knock gently and be pressed into frock 1 and get final product; To be pressed into frock 1 at last and withdraw from, check with the naked eye whether valve oil seal 3 smashes or do not pound the phenomenon that puts in place.
