Abstract
Cylinder cover of automobile engine water blocking bottom hole portion's preprocessing structure, it is characterized by comprising cylinder head body, oil-in chamber is formed with cylinder head body, the lower part of oil-in chamber is formed with cooling water chamber, the lower part of cooling water chamber be formed with cooling water recycle water hole and circulation inlet opening, there is demarcation strip between oil-in chamber and cooling water chamber, water blocking hole is provided with demarcation strip, the bottom in water blocking hole is formed with the preprocessing inclined-plane of annular.It is mainly characterized by casting cylinder cover body, the preprocessing inclined-plane of annular is just formed with the bottom in water blocking hole in advance, when to water blocking hole secondary operation internal thread, it is machined to water blocking hole bottom position, as preprocessing inclined-plane is gradually outward-dipping, annular waste material also can be fewer and fewer caused by processing, when being machined to the preprocessing incline position in water blocking bottom hole portion, just only surplus one less waste material is enclosed, even without waste material, it can easily be drawn off at this time, so as to ensure the cleannes of product cooling water chamber, avoid waste material from staying in and abnormal sound occurs in cooling water chamber.
Description
Technical field
The present invention relates to cylinder cover of automobile engine, more particularly to cylinder cover of automobile engine water blocking bottom hole portion's preprocessing
Structure.
Background technology
Engine cylinder cap is for closed cylinder and forms combustion chamber.Oil-in chamber can be all formed with engine cylinder cap
And cooling water chamber, oil-in chamber and cooling water chamber are separated through demarcation strip, water blocking hole is provided with demarcation strip, and blocked by screw plug
In casting typically the circular hole consistent with lower internal diameter suitable for reading is made in water blocking hole by water blocking hole, existing engine cylinder cap,
To water blocking hole secondary operation internal thread, the waste material of annular can be produced, when being machined to the bottom in water blocking hole, water blocking bottom hole portion is most
The larger annulus of latter circle will be fallen into cooling water chamber downwards, and it is larger to only have the aperture in a water blocking hole due to cooling water chamber,
The annulus can only take out from water blocking hole site, and the outside diameter of annulus is consistent with the water blocking hole internal diameter after processing, therefore take out ten
Divide trouble, or even can not take out, stay in cooling water chamber, influence product cleannes, and the flow of cooling water, and in cooling water
Drive the annulus to collide cooling water chamber inner wall during flowing, abnormal sound occurs.
The content of the invention
The purpose of the invention is to overcome prior art there are the shortcomings that, there is provided it is a kind of easy to process, ensure that product is cold
But cylinder cover of automobile engine water blocking bottom hole portion's preprocessing structure of the cleannes of hydroecium.
The technical solution of cylinder cover of automobile engine water blocking bottom hole portion's preprocessing structure of the present invention is：It is characterized by comprising
Cylinder head body, is formed with oil-in chamber in cylinder head body, the lower part of oil-in chamber is formed with cooling water chamber, and the lower part of cooling water chamber is formed with
Cooling water recycles water hole and circulation inlet opening, has demarcation strip between oil-in chamber and cooling water chamber, water is provided with demarcation strip
Plug-hole, the bottom in water blocking hole are formed with the preprocessing inclined-plane of annular.
The invention discloses a kind of cylinder cover of automobile engine water blocking bottom hole portion's preprocessing structure, it is mainly characterized by casting
During cylinder head body, the preprocessing inclined-plane of annular is just formed with the bottom in water blocking hole in advance, the spiral shell in water blocking hole secondary operation
During line, water blocking hole bottom position is machined to, as preprocessing inclined-plane is gradually outward-dipping, annular waste material also can caused by processing
It is fewer and fewer, when being machined to the preprocessing incline position in water blocking bottom hole portion, just only surplus one less waste material is enclosed, even without useless
Material, can easily be drawn off, so as to ensure the cleannes of product cooling water chamber, avoid waste material from staying in cooling water chamber and occur at this time
Abnormal sound.
Cylinder cover of automobile engine water blocking bottom hole portion's preprocessing structure of the present invention, the angle of inclination on the preprocessing inclined-plane
For 45 ° -60 °.
Brief description of the drawings
Fig. 1 is the structure diagram of cylinder cover of automobile engine water blocking bottom hole portion's preprocessing structure；
Fig. 2 is close-up schematic view at the A of Fig. 1.
Embodiment
The present invention relates to a kind of cylinder cover of automobile engine water blocking bottom hole portion's preprocessing structure, as shown in Fig. 1-Fig. 2, its
It is characterized in that：Including cylinder head body 1, oil-in chamber 2 is formed with cylinder head body, the lower part of oil-in chamber is formed with cooling water chamber 3, cold
But the lower part of hydroecium be formed with cooling water recycle water hole 4 and circulation inlet opening 5, have separation between oil-in chamber and cooling water chamber
Plate 6, water blocking hole 7 is provided with demarcation strip, and the bottom in water blocking hole is formed with the preprocessing inclined-plane 8 of annular.It is mainly characterized by casting gas
During cylinder cap body 1, the preprocessing inclined-plane 8 of annular is just formed with the bottom in water blocking hole 7 in advance, in 7 secondary operation of water blocking hole
During screw thread, water blocking hole bottom position is machined to, as preprocessing inclined-plane is gradually outward-dipping, annular waste material caused by processing
Can be fewer and fewer, when being machined to water blocking bottom hole portion 8 position of preprocessing inclined-plane, just only surplus one less waste material is enclosed, even without
Waste material, can be drawn off easily at this time, so as to ensure the cleannes of product cooling water chamber 3, avoid waste material from staying in cooling water chamber
Generation abnormal sound.The angle of inclination on the preprocessing inclined-plane 8 is 45 ° -60 °.
