Abstract
The invention discloses an engine valve guide pipe processing cutter, which comprises a turning tool body, wherein a slide block is fixedly arranged on the turning tool; a blade is fixedly arranged in the slide block; and one end of the turning tool body is provided with a positioning shaft, and the other end of the turning tool body is connected with a power transmission shaft. The invention further discloses a method for processing the engine valve guide pipe by using the cutter. Compared with the prior art, the invention has the advantages that: the positioning shaft is arranged in the turning tool body, so that the coaxiality between a guide pipe inner hole of the processed valve guide pipe and an oil seal installation outer circle is effectively ensured.
Description
Technical field
The present invention relates to a kind of metal cutting tool and method, relate in particular to a kind of cutter and processing method that is used to process engine valve guide.
Background technology
In the processing process of existing engine cylinder cap valve guide bushing endoporus, the processing of the processing of conduit endoporus and conduit installing hole is not in same one procedure.Because the influence of twice location, twice clamping, the position degree of conduit endoporus and conduit installing hole can have influence on the disalignment of conduit endoporus and conduit oil sealing installation cylindrical.Excessive malalignment can exert an influence to the sealing of valve oil seal, thereby the generation of engine motor oil consumption height and carbon distribution takes place.
Current, what the processing of engine valve guide endoporus was adopted is cylinder head pin-and-hole location.Because the relative cylinder head pin-and-hole of conduit endoporus has a position error, the conduit installing hole also has a position error to pin-and-hole simultaneously, and the overlapping axiality that will cause conduit endoporus and conduit oil sealing that cylindrical is installed of two position errors is bigger than normal.
Summary of the invention
The technical problem that the present invention will solve is to provide a kind of engine valve guide machining tool, to improve conduit endoporus and conduit oil sealing the axiality of cylindrical is installed.
For solving the problems of the technologies described above, valve guide bushing machining tool provided by the invention has following structure:
A kind of engine valve guide process tool comprises the lathe tool body, is installed with a slide block on the said lathe tool body, is installed with blade in the slide block, and an end of said lathe tool body is provided with locating shaft, and the other end is connected with power transmission shaft.
Preferably, said lathe tool body is provided with a groove, and said slide block is installed in this groove and through screw and is fixed.
Preferably, also be provided with on the said lathe tool body and be used for screw that the slide position is finely tuned.
Preferably, said blade is a carbide chip.
Preferably, be provided with a fluting in the said slide block, said blade is set in this fluting, and is able to fix through lock-screw.
Preferably, the other end of said lathe tool body is equipped with universal joint, and said universal joint is connected with the radial drill handle of a knife.
The present invention also provides a kind of method of utilizing above-mentioned cutter processing engine valve guide, comprises the steps:
1, valve guide bushing is pressed fit in the cylinder head;
2, processing valve guide bushing endoporus, and at oil sealing the cylindrical place is installed and retains the surplus of doing further processing;
3, definite diameter that needs to process the valve guide bushing cylindrical that obtains;
4, according to the position of blade in the determined valve guide bushing outside diameter adjustment valve guide bushing machining tool;
5, the locating shaft of valve guide bushing machining tool is inserted in the valve guide bushing endoporus to be processed, and starts machining tool and accomplish and remove oil sealing and the cylindrical surplus is installed and revises conduit endoporus and the processing that outer circles is installed.
Compared with prior art, the present invention is through being provided with locating shaft in the lathe tool body, the conduit endoporus of the valve guide bushing that has guaranteed effectively to be processed and the axiality that oil sealing is installed cylindrical.

The specific embodiment
Below in conjunction with accompanying drawing, specific embodiments of the invention is described in detail, but is to be understood that protection scope of the present invention does not receive the restriction of the specific embodiment.
To shown in Figure 3, engine valve guide machining tool of the present invention comprises lathe tool body 1 like Fig. 1, and said lathe tool body 1 is provided with a groove 5, a slide block 2 is installed in this groove 5 and is fixed through lock-screw.Wherein, also be provided with on the said lathe tool body 1 and be used for micrometer adjusting screw 7 that slide block 2 positions are adjusted.Be provided with a fluting 6 in the said slide block 2, be set with carbide chip 3 in this fluting 6, and be able to fix through lock-screw.One end of said lathe tool body 1 is provided with locating shaft 4, and the other end is equipped with universal joint, and said universal joint is connected with the radial drill handle of a knife.
Use the step of this tool processes engine valve guide to be:
1, valve guide bushing is pressed fit in the cylinder head;
2, processing valve guide bushing endoporus, and at oil sealing the cylindrical place is installed and retains the surplus of doing further processing;
3, definite diameter that needs to process the valve guide bushing cylindrical that obtains;
4, according to the position of blade in the determined valve guide bushing outside diameter adjustment valve guide bushing machining tool;
5, the locating shaft of valve guide bushing machining tool is inserted in the valve guide bushing endoporus to be processed, and starts radial drill and accomplish and remove oil sealing and the cylindrical surplus is installed and revises conduit endoporus and the processing that outer circles is installed.
The present invention has changed the localization method of processing, through locating shaft is set in cutter, has guaranteed the axiality of valve guide bushing endoporus and oil sealing installation cylindrical effectively.
More than disclosedly be merely a specific embodiment of the present invention, still, the present invention is not limited thereto, any those skilled in the art can think variation all should fall into protection scope of the present invention.
