Description
Technical field
The utility model belongs to and is specially adapted for distortion or without assembling or separated hand-operated tools or the bench device field of distortion part or article, is specifically related to a kind of assembler for valve.
Background technology
Valve is a kind of vitals of engine, valve comprises inlet valve and exhaust valve, inlet valve is responsible for to input air in engine, exhaust valve is responsible for discharging the waste gas after burning, valve all needs to coordinate valve oil seal to use, and valve oil seal is a kind of of oil sealing, generally by outer skeleton and the common sulfuration of fluorubber, is formed, oil sealing footpath oral area is provided with self-tightening spring or steel wire, for the sealing of engine valve guide rod.Valve oil seal can prevent that machine oil from entering air inlet-outlet pipe, causes machine oil to run off, and prevents mist and the discharging waste gas leakage of gasoline and air, prevents that engine motor oil from entering combustion chamber.
Because valve oil seal mainly consists of rubber bodies, spring and skeleton three parts, rubber bodies bottom flared end and conduit interference fit, realize the static seal with conduit.In prior art, during assembling valve oil seal, be all to adopt press extruding valve oil seal, realize the assembling of valve oil seal, this mode that directly applies power on valve oil seal can cause valve oil seal to be easily out of shape.
Utility model content
The defect existing for above-mentioned prior art, the on-deformable assembler for valve of valve oil seal when the purpose of this utility model is to provide a kind of valve oil seal at assembling valve.
For achieving the above object, the technical solution of the utility model is: for the assembler of valve, comprise support, wherein, also be provided with the positioning seat of valve oil seal, the fairlead of valve guide bushing, actuator and with the cylinder of piston rod, described positioning seat is fixed on support, and described fairlead is located on positioning seat; Described cylinder is located on support, and actuator is fixedly connected on piston rod, and described fairlead and positioning seat are all on piston rod mobile route.
While adopting technique scheme, valve oil seal to be assembled is positioned on positioning seat, fairlead is connected with positioning seat, then valve guide bushing is inserted in fairlead, control cylinder air inlet, the piston rod of cylinder stretches out, because fairlead and positioning seat are all on piston rod mobile route, and piston rod is provided with actuator, so when piston rod stretches out, actuator on piston rod contacts with valve guide bushing and promotes in the opening of valve guide bushing insertion valve oil seal flared end, thereby completes assembling.The utility model is when assembling valve oil seal, directly stressed is valve guide bushing, valve oil seal is located by positioning seat and is fixed, when valve guide bushing inserts valve oil seal, the main stressed frictional force that derives from valve guide bushing and valve oil seal inwall of valve oil seal, and if while assembling by extruding valve oil seal, valve oil seal is not only subject to the frictional force of valve guide bushing and valve oil seal inwall, the machinery that is also stressed directly acts on the active force on valve oil seal, thus relatively stressed less, so not yielding.
Further, described positioning seat is provided with the positioning table that coordinates a plurality of size valve oil seals, and a plurality of positioning tables form ring ladder shape, and a plurality of positioning tables of stairstepping can be for the location of different size valve oil seal ringwise.
Further, described fairlead is shaped as the cylinder of both ends open, and the one end being connected with positioning seat is provided with flange, described positioning seat link is provided with the cannelure coordinating with this flange, during assembling valve oil seal, only need, by the cannelure socket of the flange of fairlead one end and positioning seat link, just can carry out assembly work, so convenient to operation.
Further, described flange outer sides is provided with vertical positive stop strip, and described positioning seat is provided with the bar hole coordinating with positive stop strip, after fairlead is connected with positioning seat, positive stop strip coordinates with bar hole, has limited the rotation of fairlead, in assembling valve oil seal process, assembling is stable.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is that the utility model is for the structural representation of the assembler embodiment of valve;
Fig. 2 is that the utility model is for the structural representation of the assembler embodiment positioning seat of valve;
Fig. 3 is that the utility model is for the structural representation of the assembler embodiment fairlead of valve.
The specific embodiment
As shown in Figure 1, a kind of assembler for valve, comprises support 1, wherein, be also provided with the positioning seat 2 of valve oil seal, the fairlead 3 of valve guide bushing, actuator and with the cylinder 6 of piston rod 5, actuator is rubber blanket, positioning seat 2 is fixed on support 1, and fairlead 3 is located on positioning seat 2; Cylinder 6 is located on support 1, and rubber blanket 4 is fixedly connected on piston rod 5, and fairlead 3 and positioning seat 2 are all on piston rod 5 mobile routes.
In the present embodiment, as shown in Figure 2, positioning seat 2 is provided with the positioning table 11 that coordinates a plurality of size valve oil seals, and a plurality of positioning tables 11 form ring ladder shape, and a plurality of positioning tables 11 of stairstepping can be for the location of different size valve oil seal ringwise.
As shown in Figure 3, fairlead 3 is shaped as the cylinder of both ends open, and the one end being connected with positioning seat 2 is provided with flange 31, positioning seat 2 links are provided with the cannelure coordinating with this flange 31, during assembling valve oil seal, only the flange of fairlead 3 one end 31 and the cannelure of positioning seat 2 links need be socketed, just can carry out assembly work, so convenient to operation.
Flange 31 outsides are provided with vertical positive stop strip 32, positioning seat 2 is provided with the bar hole 12 coordinating with positive stop strip 32, after fairlead 3 is connected with positioning seat 2, positive stop strip 32 coordinates with bar hole 12, limited the rotation of fairlead 3, in assembling valve oil seal process, assembly precision is high and assembling process stable.
Specific works flow process:
As shown in Figure 1, valve oil seal to be assembled is positioned on the positioning table 11 of positioning seat 2 corresponding sizes, by fairlead 3 and positioning seat 2 sockets, the positive stop strip 32 now arranging in fairlead 3 lower flange 31 coordinates with the bar hole 12 on positioning seat 2, then valve guide bushing is inserted in fairlead 3, control cylinder 6 top air inlets, the piston rod 5 of cylinder 6 stretches out downwards, because fairlead 3 and positioning seat 2 are all on piston rod 5 mobile routes, and piston rod 5 is provided with rubber blanket 4, when so piston rod 5 stretches out, rubber blanket 4 on piston rod 5 contacts with valve guide bushing and promotes in the opening of valve guide bushing insertion valve oil seal flared end, thereby complete assembling.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
