Abstract
The invention provides a V-shaped cylinder cover blank, which comprises a cylinder cover blank body and two groups of clamping blocks arranged on two end surfaces of the cylinder cover blank body; and the clamping surfaces of the clamping blocks are parallel to the combustion chamber surface of the V-shaped cylinder cover blank. Such structure realizes that the locating surface of a fixture clings to the clamping surface of the clamping block in the process of clamping the whole V-shaped cylinder cover, and the combustion chamber blank surface can be very easily adjusted to be vertical to a main shaft, so that the processing difficulty of the V-shaped cylinder cover on the combustion chamber surface and the holes on the combustion chamber surface is lowered; and the whole clamping surface is formed in a casting manner by a metal mould, so that the surface quality and the spatial location are better, and the processing accuracy of the combustion chamber surface and the holes on the combustion chamber surface can be effectively improved. The invention also provides a combustion chamber processing method for the V-shaped cylinder cover.
Description
Technical field
The present invention relates to cylinder manufacturing technology field, more particularly, relate to the combustion chamber processing method of a kind of cylinder in V-arrangement lid blank and cylinder in V-arrangement lid.
Background technology
In automobile industry, any product is when machining, and choosing of coarse positioning unreasonablely will directly have influence on difficulty of processing, efficiency and the quality etc. of product.Due to cylinder in V-arrangement cover frame face and combustion chamber face not parallel, and the clamping face of fixture parallels with the combustion chamber face of cylinder head, so the retaining part of its frame face contacts limited with the clamping face of fixture, and when being rough milled, combustion chamber face there is no a datum level, so can affect stable position and crudy to the combustion chamber face of cylinder head, therefore when rough milling combustion chamber face, there is no reasonably thick datum level, this has increased difficulty of processing and the time of cylinder in V-arrangement lid, and then causes the combustion chamber face at every turn processing to have larger difference.
Therefore, how providing a kind of cylinder in V-arrangement lid blank, to guarantee that cylinder in V-arrangement covers the crudy to combustion chamber face in process, is current those skilled in the art's problem demanding prompt solution.
Summary of the invention
In view of this, the invention provides a kind of cylinder in V-arrangement lid blank, to realize cylinder in V-arrangement, cover the crudy to combustion chamber face in process.
In order to achieve the above object, the invention provides following technical scheme:
A cylinder in V-arrangement lid blank, comprises cylinder head blank body and is arranged on two groups of its both ends of the surface clamping piece, described in clamp piece the face that clamps parallel with the combustion chamber face that described cylinder in V-arrangement covers on blank;
Every group clamps piece is that two bar shapeds that are parallel to each other clamp piece;
Describedly clamp piece and described cylinder head blank body is integral type structure.
Based on the above-mentioned cylinder in V-arrangement lid blank providing, the present invention also provides a kind of combustion chamber processing method of cylinder in V-arrangement lid, and the cylinder in V-arrangement lid blank as above-mentioned any one is processed, and comprises the following steps:
1) adopt fixture to clamp the described piece that clamps;
2) the combustion chamber face of cylinder in V-arrangement lid is carried out to rough milling;
3) the combustion chamber face of cylinder in V-arrangement lid is carried out to finish-milling processing;
4) described in removal, clamp piece.
Preferably, in the combustion chamber processing method of above-mentioned cylinder in V-arrangement lid, after step 4), also comprise and polishing to clamping the position of piece described in removal on cylinder in V-arrangement lid blank.
In cylinder in V-arrangement lid blank provided by the invention, two groups of faces that clamp that clamp piece that arrange on cylinder head blank body parallel with the combustion chamber face of described cylinder in V-arrangement lid blank, this kind of structure covered in the process clamping whole cylinder in V-arrangement, the locating surface that clamps of fixture fits with the face that clamps that clamps piece, can very easily combustion chamber black skin be adjusted into perpendicular to main shaft, having reduced cylinder in V-arrangement lid, to be difficult to process Mian Shang hole, Mian Ji combustion chamber, combustion chamber be difficulty, because the whole face that clamps is metal die casting and forms, surface quality and locus are better, can effectively improve the machining accuracy of Mian Shang hole, Mian Ji combustion chamber, combustion chamber system.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The cylinder in V-arrangement that Fig. 1 provides for the embodiment of the present invention covers the structural representation of blank;
