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 for processing cutter and the processing method of engine valve guide.
Background technology
In the processing process of existing engine cylinder cap valve guide bushing endoporus, the processing of the processing of guide pipe inner hole and conduit installing hole is not at same procedure.Due to the impact of twice location, twice clamping, the position degree of guide pipe inner hole and conduit installing hole can have influence on the disalignment of guide pipe inner hole and conduit oil sealing installation cylindrical.Excessive malalignment can exert an influence to the sealing of valve oil seal, thereby generation Oil Consumption of Engine is high and the generation of carbon distribution.
Current, what the processing of engine valve guide endoporus adopted is cylinder head pin-and-hole location.Because the relative cylinder head pin-and-hole of guide pipe inner hole has a position error, conduit installing hole also has a position error to pin-and-hole simultaneously, and the overlapping of two position errors will cause the axiality of guide pipe inner hole and conduit oil sealing installation cylindrical bigger than normal.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of engine valve guide machining tool, and the axiality of cylindrical is installed to improve guide pipe inner hole and conduit oil sealing.
For solving the problems of the technologies described above, valve guide bushing machining tool provided by the invention has following structure:
, comprise lathe tool body, on described lathe tool body, be installed with a slide block, in slide block, be installed with blade, one end of described lathe tool body is provided with locating shaft, and the other end is connected with power transmission shaft.
Preferably, on described lathe tool body, be provided with a groove, described slide block is installed in this groove and by screw and is fixed.
Preferably, on described lathe tool body, be also provided with the screw for slide position is finely tuned.
Preferably, described blade is carbide chip.
Preferably, be provided with a fluting in described slide block, described blade sleeve is loaded in this fluting, and is fixed by lock-screw.
Preferably, the other end of described lathe tool body is provided with universal joint, and described universal joint is connected with radial drill handle of a knife.
The present invention also provides a kind of method of utilizing above-mentioned tool sharpening engine valve guide, comprises the steps:
1, pressing of valve guide pipe is entered in cylinder head;
2, processing valve guide bushing endoporus, and at oil sealing, cylindrical place is installed and retains the surplus of doing further processing;
3, determine the outer diameter of a circle of the valve guide bushing that needs processing to obtain;
4, according to the position of blade in 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 valve guide bushing endoporus to be processed, and starts the processing that machining tool completes removal oil sealing installation cylindrical surplus and revises guide pipe inner hole and outer circles is installed.
Compared with prior art, the present invention, by locating shaft being set in lathe tool body, has guaranteed the guide pipe inner hole of valve guide bushing and the axiality of oil sealing installation cylindrical of processing effectively.

The mark using in above accompanying drawing is respectively:
1-lathe tool body, 2-slide block, 3-blade, 4-locating shaft, 5-groove, 6-fluting, 7-micrometer adjusting screw.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention is not subject to the restriction of the specific embodiment.
As shown in Figure 1 to Figure 3, engine valve guide machining tool of the present invention comprises lathe tool body 1, is provided with a groove 5 on described lathe tool body 1, a slide block 2 is installed in this groove 5 and is fixed by lock-screw.Wherein, on described lathe tool body 1, be also provided with the micrometer adjusting screw 7 for slide block 2 positions are adjusted.In described slide block 2, be provided with a fluting 6, in this fluting 6, be set with carbide chip 3, and fixed by lock-screw.One end of described lathe tool body 1 is provided with locating shaft 4, and the other end is provided with universal joint, and described universal joint is connected with radial drill handle of a knife.
Use the step of this tool processes engine valve guide to be:
1, pressing of valve guide pipe is entered in cylinder head;
2, processing valve guide bushing endoporus, and at oil sealing, cylindrical place is installed and retains the surplus of doing further processing;
3, determine the outer diameter of a circle of the valve guide bushing that needs processing to obtain;
4, according to the position of blade in 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 valve guide bushing endoporus to be processed, and starts the processing that radial drill completes removal oil sealing installation cylindrical surplus and revises guide pipe inner hole and outer circles is installed.
The present invention has changed the localization method of processing, by locating shaft is set in cutter, has effectively guaranteed the axiality of valve guide bushing endoporus and oil sealing installation cylindrical.
Disclosed is above only a specific embodiment of the present invention, and still, the present invention is not limited thereto, and the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
