Abstract
The invention discloses a diesel engine cylinder cover relating to a diesel engine spare part. The cylinder cover is provided with an oil atomizer mounting hole; seat rings at both ends of the mounting hole and a hole body in the middle are cast together; and the mounting hole has the wall thickness of 5-6mm. The invention changes the sleeving mode of the traditional oil atomizer mounting hole into an integral mode, has enhanced wall thickness and even wall thickness without extrusion pressure, avoids a crack phenomenon due to thermal fatigue damage in work, eliminates hidden accident danger; and because of saving a copper sleeve, the invention can save the material, simplify the processing process and decrease the cost.
Description
Technical field
The present invention relates to a kind of parts and components of diesel engine, particularly cylinder cover for diesel engine.
Background technique
Cylinder cover for diesel engine is loaded on cylinder body top, is used for plane on the sealing cylinder, and forms the firing chamber jointly with cylinder and piston head.Cylinder of diesel engine covers oil sprayer, inlet and outlet door, air inlet and exhaust piper and pitman arm shaft assembly etc. is housed usually, and cylinder head inner inlet and outlet road, cooling jacket and Oil passage etc. in addition are the cast members of a complexity.For the direct injection combustion chamber diesel engine, adopt the direct injection fuel injector device, mounting hole of oil sprayer is the seat ring that processes two ends on cylinder head earlier, again will be as the copper sheathing pressure-mounting of hole body to seat ring, this edge nested structure, the cylinder cap rough-cast is easier to, helps improving the cast member yield rate, the counter race position produces internal stress but copper sheathing is pressed into the back, the heat fatigue destroying infection, easily crack, cause cylinder head gas leakage, leak, cause accident; And be pressed into the structure of copper sheathing, and consumptive material is consuming time, and cost strengthens.
Summary of the invention
The object of the present invention is to provide a kind of mounting hole of oil sprayer of avoiding to ftracture, remove a hidden danger, and the cylinder cover for diesel engine that can cut down finished cost.
Technological scheme of the present invention is: the seat ring at the mounting hole of oil sprayer two ends that cylinder of diesel engine covers and the hole body at middle part are cast as one.
Described mounting hole of oil sprayer wall thickness 5-6mm.
The present invention changes mounting hole of oil sprayer into integrated type by original edge shell type, and wall thickness increases to some extent, and wall thickness is even, and no extrusion stress is subjected to cracking phenomena can not taking place when thermal fatigue is destroyed so at work, eliminates accident potential; Along with the raising of modern foundry engieering, adopt measures such as increasing air outlet hole at external mold, the cast inblock yield rate of mounting hole is improved, this programme is achieved, and the present invention need not inlay copper sheathing, can save material, simplifies manufacturing procedure, reduces cost.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Embodiment
As figure, cylinder cover for diesel engine 1 is provided with mounting hole of oil sprayer 2, and this mounting hole is the cast inblock formula, and promptly the hole body at the seat ring at mounting hole two ends and middle part is cast as one, and the mounting hole wall thickness is 5mm.
Claims (2)
1. cylinder cover for diesel engine, cylinder head is provided with mounting hole of oil sprayer, it is characterized in that the seat ring at described mounting hole of oil sprayer two ends and the hole body at middle part are cast as one.
2. by the described cylinder cover for diesel engine of claim 1, it is characterized in that: described mounting hole of oil sprayer wall thickness 5-6mm.
