Abstract

The utility model discloses a cylinder head, it includes: the body, it includes a plurality of pipe portions that form with the integrative casting of this body, and with the pipe hole that pipe portion quantity is the same, the pipe hole sets up in the pipe portion. The utility model discloses directly cast pipe and body as an organic wholely, only can process out the pipe hole through once fixing a position, avoid the position degree of the pipe hole that the multiple bearing leads to not to be conform to the requirement, such structure is simpler, has also reduced the quantity of part, has reduced the step of machine tooling, has reduced the processing cost.

Description

Cylinder head

Technical field

The utility model relates to a kind of engine art, particularly a kind of cylinder head.

Background technology

In prior art, as Figure 1-3, the guide pipe inner hole in the cylinder head of Diesel engine is by as followsMethod is manufactured:

First the body 10 of casting cylinder cover, is then clamped in body 10 on lathe, on body 10Processing conduit installing hole 110. Then, conduit 2 is press-fited in conduit installing hole 110. Then by body10 are clamped to the endoporus 21 that processes conduit 2 on lathe again.

Although processing conduit installing hole 110 and endoporus 21 all, with the location, bottom surface of body 10, pass throughTwice repeatedly after positioning and clamping, machine tool cannot ensure the position degree of endoporus 21 and conduit installing hole 110.

The information that is disclosed in this background technology part is only intended to increase to general background of the present utility modelUnderstand, and should not be regarded as admitting or imply that in any form this information structure has been the general skill in this areaThe prior art that art personnel are known.

Utility model content

The purpose of this utility model is to provide a kind of cylinder head, thereby overcomes the conduit of existing cylinder headThe processing method of endoporus cannot ensure the defect of the position degree of the conduit installing hole of guide pipe inner hole and cylinder head.

For achieving the above object, the utility model provides a kind of cylinder head, comprising: body, it comprisesThe multiple conduit part that form with this body integrally casting; And the guide pipe inner hole identical with conduit part quantity,Guide pipe inner hole is arranged in conduit part.

Preferably, in technique scheme, guide pipe inner hole forms by machining.

Compared with prior art, the utlity model has following beneficial effect:

The utility model is directly cast as one conduit and body, only can be processed and be led by one-time positioningPipe orifice, avoids the position degree of the guide pipe inner hole that multiple bearing causes undesirable; Such structure moreSimply, also reduce the quantity of part, reduced mach step, reduced processing cost.

Detailed description of the invention

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail, but should managesSeparate protection domain of the present utility model and be not subject to the restriction of detailed description of the invention.

Unless separately have other clearly to represent, otherwise in whole description and claims, term " comprised "Or its conversion element or the part of stating being understood to include as " comprising " or " including " etc.,And do not get rid of other element or other part.

As follows according to the manufacture method of the guide pipe inner hole of the cylinder head of the utility model detailed description of the invention:

First the body 1 that casts out cylinder head, this body is provided with multiple conduit part, that is to say direct generalBody and conduit are cast as one, and without process conduit installing hole on body, have reduced by a secondary body by fixedThe chance of position on lathe.

Then, body 1 is clamped on lathe, processes guide pipe inner hole 11 in conduit part.

As shown in Figure 4, on the body 1 of the cylinder head of manufacture place, be only provided with guide pipe inner hole according to the method described above11, there is not conduit installing hole of the prior art.

The aforementioned description to concrete exemplary of the present utility model is in order to illustrate and the order of illustration. These descriptions not want the utility model to be defined as disclosed precise forms, and obviously,According to above-mentioned instruction, can much change and change. Exemplary embodiment is selected and describedObject be to explain certain principles of the present utility model and practical application thereof, thereby make the skill of this areaArt personnel can realize and utilize various exemplary of the present utility model and variousSame selection and change. Scope of the present utility model is intended to be limited by claims and equivalents thereof.
