Description
Technical field
The utility model relates to a kind of machining tool, particularly a kind of cutter of falling the spiracle line that is exclusively used in the processing of engine cylinder cover spiracle line.
Background technology
In the engine manufacturing of automobile, motorcycle, the processing of the spiracle line of engine cylinder cover is the operation of one key.Engine cylinder covers on the valve seating that is bumped into, has the valve-seat bore that cooperates the formation sealing with valve, the structure of valve-seat bore is special, endless belt face with three different angles, usually the sealed working face that contacts with valve is a spiracle line, angle between sealing working face and the valve-seat bore axis is generally 45 °, the inner horn ring zone face and the angle between the valve-seat bore axis of sealed working face top are generally 30 °, and the exterior angle endless belt face of sealed working face below and the angle between the valve-seat bore axis are generally 60 °.The sealed working face width of valve seating is made as 1～1.8mm because of the specification difference of engine, as the seal operation face width, be easy to generate carbon black, influence valve sealing; Narrow as sealed working face, cooling effect descends, and can quicken the wearing and tearing of valve face, influences valve sealing equally.Therefore the sealed working face that contacts with valve is the requirement on machining accuracy height of spiracle line, could guarantee good sealing property, and valve-seat bore processing to keep with cylinder cover on valve guide hole processing concentric, so the cutter of processing spiracle line normally is separately installed with ream inner horn ring zone face blade on the handle of a knife of the reamer that cuts with scissors valve guide hole at present, ream sealed working face blade, ream exterior angle endless belt face blade.The cutter of this structure, because of the hinge valve guide hole reamer and handle of a knife be to be rigidly connected, and being cantilever, stretches out by reamer, the extension elongation of reamer is long, reamer also need continue feeding after having cut with scissors valve guide hole, the ream inner horn ring zone face blade of installing on the handle of a knife, ream sealed working face blade, ream exterior angle endless belt face blade ream successively go out inner horn ring zone face, sealed working face, exterior angle endless belt face and form spiracle line; But,, be to be rigidly connected with handle of a knife because the reamer extension elongation is long, a bit swing of reamer in continuing the feeding process all can influence the crudy of spiracle line, and the circularity of spiracle line can not get guaranteeing, roughness can not get guaranteeing that the axiality of spiracle line and valve guide hole can not get guaranteeing; So this one-time continuous feeding hinge air outlet valve guide hole that adopts usually and the cutter of ream air outlet valve line, because the defective that self structure exists, be difficult to guarantee the precision and the quality of spiracle line processing, make cylinder cover when the ream spiracle line, produce substandard products, the requirement that does not reach valve sealing easily.For overcoming the shortcoming that above-mentioned tradition processing spiracle line cutter exists, instrument Co., Ltd of Dalian Fuji has produced a kind of cutter, and this cutter is provided with the reamer that slides and release in the handle of a knife of reamer, relies on the cutter tooth guiding, the sliding sleeve of reamer is long, and reamer is by a drive power source; The cutter that is used for ream valve seating interior angle, exterior angle is installed respectively at reamer handle of a knife front end, with the cutter that is used for the boring spiracle line, and the boring cutter that is used for the cutter of boring spiracle line adopts custom-designed sharp knife, wherein the cutter at ream valve seating interior angle, exterior angle is by another drive power source, the cutter of boring spiracle line is again by an other drive power source, reamer guide tube hole like this, the inside and outside angle of ream, three work steps of boring spiracle line cause using the lathe of this structure cutter that three power sources need be set driving fraising respectively, the inside and outside angle of ream, the boring spiracle line.This cutter uses on the special purpose machine tool at this Tool Design, and the machining accuracy of spiracle line is improved, and is more outstanding than the cutter of traditional processing spiracle line.But, this cutter fraising, exterior angle in the ream, three part-structures of three work steps of boring spiracle line need be used three drive power source respectively, its complex structure, and the bodily form is huge, cost of manufacture is big, and the selling price costliness can increase the cost of user's processing vapor head valve line thus; The cutter of this structure can not be general simultaneously, processes the spiracle line of the cylinder cover of different size model, needs to change the cutter of different specifications, causes the further increasing of user cost thus.And this cutter also need be equipped with the special machine tool that uses this cutter, and the price of the machine tool that this is special is also expensive, buys a set of equipment and cutter usually and needs 60～900,000 yuan, has increased the burden of enterprise.
