Abstract
The utility model discloses an engine air passage structure with a processing platform, which comprises a cylinder cover, wherein an air passage is arranged in the cylinder cover; the processing platform is arranged on the outer side surface of the air passage in a position where a guide pipe mounting hole of the engine is formed and perpendicular to the guide pipe axis of the engine. The engine air passage structure has the advantages that the machining processes are reduced; the cutting metal is reduced; the machining manufacturability of a cylinder cover product is improved; the arrangement is simple, convenient and practical.
Description
Technical field
The utility model relates to engine art, a kind of air passage structure for engine with processing platform of concrete finger.
Background technique
The engine air flue core profile rounding off of developing both at home and abroad at present, the cylinder-cover blank air flue poured into and cylinder cap form smooth curved surface, for guaranteeing the coaxality requirement of valve seat mounting hole and conduit mounting hole, need to be with a cutter with adding valve seat mounting hole and conduit mounting hole opportunity, so just need to add this hole from the combustion chamber steering wheel, and existing cylinder-cover blank air flue consists of the inclination smooth curved surface, cutter adds in process easily partially sliding at machine, generally needs elder generation machine on the inclination curved surface adds a platform at present, the drilling tool of being convenient to follow-up valve seat guide hole is located on platform, machining valve seat mounting hole and conduit mounting hole, complex procedures like this, the attenuating of cylinder cap mechanical processing technique.
Summary of the invention
The purpose of this utility model is exactly machining valve seat mounting hole and the conduit mounting hole technique that will overcome above-mentioned complexity, provides a kind of manufacture simplification, efficiently with the air passage structure for engine of boss.
For achieving the above object, the air passage structure for engine with processing platform that the utility model is designed, comprise cylinder head, in cylinder head, be provided with air flue, its special way is: described air flue outer side surface is provided with processing platform, and described processing platform is arranged on engine duct mounting hole position place and perpendicular to the engine duct axis.
Further, the diameter of described processing platform is than the little 1 ~ 3mm of the diameter of conduit mounting hole.
Further, described processing platform is pit.
Again further, the degree of depth of described pit is 5 ~ 10mm.
The utility model has the advantage of: pit is set on engine air flue, for subsequent product machining conduit mounting hole provides the technique plane, be convenient to the processing of further conduit mounting hole, reduced machining processes, reduced the cutting metal amount, improve cylinder cap product mechanical processing technique, and arrange simple, simple and practical.
The accompanying drawing explanation
Fig. 1 is the structural representation of the air passage structure for engine of the utility model band processing plane.
Fig. 2 is air flue casting sand core structural representation.
Fig. 3 is the air passage structure for engine schematic diagram of having processed the conduit mounting hole.
In figure: air flue 1, pit 2, cylinder head 3, engine duct mounting hole 4, engine duct axis 5, air flue casting sand core 6, boss 7.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
The air passage structure for engine with processing platform shown in figure, comprise cylinder head 3, in cylinder head 3, be provided with air flue 1, air flue 1 outer side surface is provided with processing platform, in this scheme, processing platform is pit 2, pit 2 is arranged on engine duct mounting hole 4 position places and perpendicular to engine duct axis 5, it is good that the diameter of processing platform is traditionally arranged to be than the little 1 ~ 3mm of the diameter of conduit mounting hole 4, and it is good that the degree of depth of processing platform generally is made as 5 ~ 10mm.The utility model has utilized air flue casting sand core 6, described air flue casting sand core 6 outsides are provided with boss 7, by air flue casting sand core 6 cylinder head 3, after casting complete, forming and making a concession pit 2 with boss 7 contacting points, for processing engine duct mounting hole 4 provides processing platform.So just reduced the operation on mechanical processing technique plane, the plane formed by casting substitutes general mechanical processing technique plane, has reduced the machining order, has reduced the cutting metal amount, improves cylinder cap product mechanical processing technique; And arrange simple, simple and practical.
