Abstract
The utility model discloses a kind of integrated cylinder header structure, the rocker arm support comprising cylinder head matrix and be positioned on cylinder head matrix, cylinder head matrix and rocker arm support integrally casting shaping, be provided with the camshaft hole having cast aft-loaded airfoil between cylinder head matrix and rocker arm support.This integrated cylinder header structure by cylinder head matrix and rocker arm support by after casting integrated completing, carry out the assembling of the parts such as processing and camshaft of the positions, hole such as camshaft hole, this all-in-one-piece air cylinder head structure can better ensure the assembly precision of the assemblies such as the machining accuracy of air cylinder head structure and cam, and this model utility is used for engine art.
Description
Technical field
The utility model relates to engine art, particularly relates to a kind of integrated cylinder header structure.
Background technique
The cylinder head of existing chain motor, all makes split-type structural, i.e. cylinder head body and rocker arm support separate machined, and such way meets the Economy of Product processing, but is difficult to the coaxality and the circularity that ensure camshaft hole, and homogeneity of product is poor.
Model utility content
For solving the problem, the utility model provides a kind of monolithic cylinder header structure that better can ensure assembly precision.
The utility model solves the technological scheme that its technical problem adopts:
A kind of integrated cylinder header structure, the rocker arm support comprising cylinder head matrix and be positioned on cylinder head matrix, cylinder head matrix and rocker arm support integrally casting shaping, be provided with the camshaft hole having cast aft-loaded airfoil between cylinder head matrix and rocker arm support.
Be further used as the improvement of technical solutions of the utility model, rocker arm support is provided with the rocker shaft hole having cast aft-loaded airfoil at rocker arm support.
Be further used as the improvement of technical solutions of the utility model, the side of cylinder head matrix is also provided with suspension bracket hole.
Be further used as the improvement of technical solutions of the utility model, the side of cylinder head matrix is provided with hanger arm, and the top of hanger arm is provided with two symmetrically arranged suspension bracket holes.
The beneficial effects of the utility model: this integrated cylinder header structure by cylinder head matrix and rocker arm support by after casting integrated completing, carry out the assembling of the parts such as processing and camshaft of the positions, hole such as camshaft hole, this all-in-one-piece air cylinder head structure can better ensure the assembly precision of the assembly such as machining accuracy and cam of air cylinder head structure.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model embodiment overall structure schematic diagram;
Fig. 2 is the utility model embodiment overall structure plan view.
Embodiment
With reference to Fig. 1, Fig. 2, the utility model is a kind of integrated cylinder header structure, comprise cylinder head matrix 1 and be positioned at the rocker arm support 2 on cylinder head matrix 1, cylinder head matrix 1 and rocker arm support 2 integrally casting shaping, be provided with the camshaft hole 3 having cast aft-loaded airfoil between cylinder head matrix 1 and rocker arm support 2.
This integrated cylinder header structure by cylinder head matrix 1 and rocker arm support 2 by after casting integrated completing, carry out the assembling of the parts such as processing and camshaft of the positions, hole such as camshaft hole 3, this all-in-one-piece air cylinder head structure can better ensure the assembly precision of the assembly such as machining accuracy and cam of air cylinder head structure.
As the utility model preferred embodiment, rocker arm support 2 is provided with the rocker shaft hole 21 having cast aft-loaded airfoil at rocker arm support 2.
As the utility model preferred embodiment, the side of cylinder head matrix 1 is also provided with suspension bracket hole 4.
As the utility model preferred embodiment, the side of cylinder head matrix 1 is provided with hanger arm 41, and the top of hanger arm 41 is provided with two symmetrically arranged suspension bracket holes 4.
Air cylinder head structure in the past, due to the limitation of casting technique, cannot carry out cast inblock, after improvement casting technique, the cylinder head matrix 1 of composition cylinder head and rocker arm support 2 is carried out cast inblock, can save production technology and the cost of production of cylinder head.
Integrally manufactured air cylinder head structure, relatively in the past modular air cylinder head structure, can better ensure the assembly precision between cylinder head matrix 1 and rocker arm support 2, better ensures the installation precision of camshaft simultaneously.
Hanger arm 41 is arranged on the side of cylinder head matrix 1, and two the symmetrical suspension bracket holes 4 arranged on hanger arm 41, Integral cylinder head that can be conveniently larger to weight carries out lifting transhipment.
Certainly, the invention is not limited to above-mentioned mode of execution, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
