Description
Technical field
The present invention relates to cylinder cover of automobile engine, more particularly to the wide arc gap side of cylinder cover of automobile engine tappet bore
Through hole.
Background technology
Tappet bore can be all formed with the cylinder head of engine, the side of tappet bore is formed with oil-in chamber, in tappet bore and oil
There is tappet ring wall to block between chamber, only small―gap suture communicates both, and prior art is typically by the lower end system of tappet ring wall
Transition at a right angle, and air intake duct side wall corresponding with the right angle transition position and exhaust duct side wall are plane, which causes
The gap of the position is very small, and the impurity such as caused drilling cuttings is easily stuck in this so when processing tappet bore and neighbouring structure
Small clearance position, so as to influence the cleannes of product, even results in position blocking, causes whole engine cylinder cap to scrap.
The content of the invention
The purpose of the invention is to overcome prior art there are the shortcomings that, there is provided one kind increase tappet ring wall and air intake duct
The gap of side wall and exhaust duct side wall, and rounding off, are conducive to the impurity such as drilling cuttings and pass through the automobile of raising product cleannes
The wide arc gap side through hole of engine cylinder cap tappet bore.
The technical solution of the wide arc gap side through hole of cylinder cover of automobile engine tappet bore of the present invention is：It is characterized by comprising
Cylinder head body, is formed with air intake duct, exhaust duct, tappet bore and oil-in chamber in cylinder head body, the side wall of air intake duct be formed with into
Airway walls, the side wall of exhaust duct are formed with exhaust duct wall, and the side wall of tappet bore is formed with tappet ring wall, and the lower end of tappet ring wall is formed with circle
Arc transition face, there is a left small―gap suture between the tappet ring wall lower end in left side and air intake duct wall, the tappet bore in left side through left small―gap suture with
The oil-in chamber in left side communicates, and left cancave cambered surface, the arc transition of left cancave cambered surface and left side tappet ring wall are formed with air intake duct wall outer wall
Face is corresponding, has right small―gap suture between the tappet ring wall lower end on right side and air intake duct wall, the tappet bore on right side is through right small―gap suture
Communicated with the oil-in chamber on right side, right cancave cambered surface, the circular arc mistake of right cancave cambered surface and right side tappet ring wall are formed with exhaust duct wall outer wall
It is corresponding to cross face.
The invention discloses a kind of wide arc gap side through hole of cylinder cover of automobile engine tappet bore, it is mainly characterized by tappet
The lower end of ring wall is formed with arc-shaped transitional surface, and left cancave cambered surface, left cancave cambered surface and left side tappet ring wall are formed with the outer wall of air intake duct wall
Arc-shaped transitional surface it is corresponding, be formed with right cancave cambered surface in the outer wall of exhaust duct wall, the circular arc of right cancave cambered surface and right side tappet ring wall
Transition face is corresponding, can so increase the gap between tappet ring wall and air intake duct wall and exhaust duct wall, and make the position
Transition is rounder and more smooth, so as to process tappet bore and will not to be stuck in this left and right for the impurity such as caused drilling cuttings during neighbouring structure
Small clearance position, makes drilling cuttings be easier to be rinsed out, improves the cleannes of product, ensures its service life, reduces rejection rate.

Embodiment
The present invention relates to a kind of wide arc gap side through hole of cylinder cover of automobile engine tappet bore, as shown in Fig. 1-Fig. 4, its
It is characterized in that：Including cylinder head body 1, air intake duct 2, exhaust duct 3, tappet bore 4 and oil-in chamber 5 are formed with cylinder head body,
The side wall of air intake duct is formed with air intake duct wall 6, and the side wall of exhaust duct is formed with exhaust duct wall 7, and the side wall of tappet bore is formed with tappet ring wall
8, the lower end of tappet ring wall is formed with arc-shaped transitional surface 9, has left small―gap suture between 8 lower end of tappet ring wall in left side and air intake duct wall 6
10, the tappet bore 4 in left side is communicated through left small―gap suture with the oil-in chamber 5 in left side, and left cancave cambered surface 11 is formed with 6 outer wall of air intake duct wall,
Left cancave cambered surface is corresponding with the arc-shaped transitional surface 9 of left side tappet ring wall 8,8 lower end of tappet ring wall on right side and air intake duct wall 6 it
Between have right small―gap suture 12, the tappet bore 4 on right side is communicated with the oil-in chamber 5 on right side through right small―gap suture, is formed with 7 outer wall of exhaust duct wall
Right cancave cambered surface 13, right cancave cambered surface are corresponding with the arc-shaped transitional surface 9 of right side tappet ring wall 8.It is mainly characterized by tappet ring wall 8
Lower end is formed with arc-shaped transitional surface 9, and left cancave cambered surface 11, left cancave cambered surface and left side tappet ring wall 8 are formed with the outer wall of air intake duct wall 6
Arc-shaped transitional surface 9 is corresponding, and right cancave cambered surface 13, the circle of right cancave cambered surface and right side tappet ring wall 8 are formed with the outer wall of exhaust duct wall 7
Arc transition face 9 is corresponding, can so increase the gap between tappet ring wall and air intake duct wall 6 and exhaust duct wall 7, and make this
Position transition is rounder and more smooth, so that the impurity such as caused drilling cuttings will not be stuck in this when processing tappet bore 4 and neighbouring structure
Left and right small―gap suture 10,12 positions, make drilling cuttings be easier to be rinsed out, improve the cleannes of product, ensure its service life,
Reduce rejection rate.
