Specific embodiment
In view of this, core of the invention is to provide a kind of processing technology of loaded cylinder, used with reducing engine
Security risk present in journey.Another core of the invention is providing a kind of loaded cylinder using above-mentioned processing technology.
In order to enable those skilled in the art to better understand the solution of the present invention, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.
As shown in Figure 3 and Figure 4, the invention discloses a kind of loaded cylinders in processing, and dress is first processed on the end face of inner cylinder 1
The construction section 3 of distribution, then inner cylinder 1 and runner outer wall 2 are welded, the construction section 3 of the pilot hole is then sealed, pilot hole is reprocessed
Load segment 4.
Specific procedure of processing is as follows：
Step S1：The construction section in process and assemble hole on the predeterminated position of the end face of inner cylinder.
The construction section 3 of the pilot hole is directly processed when inner cylinder 1 is processed, specifically, can pass through several Milling Machinings.This Shen
Please in predeterminated position be former loaded cylinder pilot hole Position Approximate, due to the construction section 3 of pilot hole be not intended to and other
The part of component assembling, therefore, the status requirement of the construction section 3 are lower, do not need to be accurately positioned.
Step S2：The inner cylinder for processing construction section and runner outer wall are welded, and formed between inner cylinder and runner outer wall
Inner cavity, and above-mentioned construction section is connected to inner cavity.
Inner cylinder 1 and runner outer wall 2 are welded again after processing construction section 3, which is connected to inner cavity, on the one hand needs
It completes pipeline with inner cavity connection, on the other hand can also reduce the requirement to assembly hole site.
Step S3：Seal the construction section of pilot hole.
The construction section 3 of pilot hole is sealed, inner cavity and extraneous connection can be prevented in this way, is prevented in extraneous impurity entrance
Chamber avoids the pollution of inner cavity.
Step S4：The end face positioning of inner cylinder and runner outer wall after welding, and the load segment in process and assemble hole, open peace
Section is filled, and the construction section is connected to corresponding load segment.
It since construction section 3 is connected to inner cavity, is not used to assemble, therefore, low to the positioning requirements of construction section 3, Er Qie
When process and assemble section 4, construction section 3 can be sealed, obstruct the connection of load segment 3 Yu inner cavity, it is therefore prevented that iron filings and other
Impurity is fallen into inner cavity, to fundamentally prevent the pollution of inner cavity, greatly reduces and exists in engine use process
Security risk.
The construction section 3 of pilot hole in the application is stepped hole, and one section of the diameter far from inner cavity is greater than close to interior
One section of diameter of chamber.Furthermore the purpose for stepped hole being arranged is sealed for the ease of the construction section 3 to pilot hole.In reality
In, the size of stepped hole can be set as needed, specifically, one section of the diameter that can will be close to inner cavity is set as 9.5mm, it will
One section of the diameter far from inner cavity is set as 10.25mm.
There is provided herein the sealing means of construction section 3, specifically, installing the protective plug of elasticity in construction section 3 to realize
Sealing to construction section 3.One section of diameter of the stepped hole close to inner cavity in the application is smaller, blocks protective plug to facilitate.It adopts
With the mode not only good airproof performance, but also easy disassembly of spring protective plug.
In order to avoid influencing the processing to the load segment 4 of pilot hole, it is preferred that protective plug is arranged close in construction section 3
One section of inner cavity.It is lower than the depth of the load segment 4 of pilot hole after mounting for protective plug.
In another embodiment, also threaded hole can be set by the construction section 3 of pilot hole, and is pacified by screw element sealing cover
Fill section 3.As long as it will be appreciated by persons skilled in the art that can be realized it is being connected to inner cavity and can dismountable mode it is equal
In protection scope.
Based on the above technical solution, the diameter of the construction section of pilot hole 3 is set smaller than to the assembly of pilot hole
The diameter of section 4.It, can be directly on the basis of construction section 3 when the load segment 4 to pilot hole is processed in conjunction with above-mentioned setting
Expand a hole to come out.
The processing of load segment 4 can be completed by way of several Milling Machinings.
In addition, including the inner cylinder 1 and runner outer wall 2 welded together, the two exists disclosed herein as well is a kind of loaded cylinder
Gap is formed between after welding, and end face has pilot hole, the core of the application is that the pilot hole includes for assembly
The construction section 3 of load segment 4 and removable seal, wherein construction section 3 is connected to inner cavity, and load segment 4 can connect with construction section 3
It is logical.
It since construction section 3 is connected to inner cavity, is not used to assemble, therefore, the positioning requirements of construction section 3 is reduced, and
In process and assemble section 4, construction section 3 can be sealed, obstruct the connection of load segment 4 Yu inner cavity, it is therefore prevented that iron filings and its
He falls into inner cavity impurity, to fundamentally prevent the pollution of inner cavity, greatly reduces and deposits in engine use process
Security risk.
The structure in the structure of construction section 3 and load segment 4 and the processing technology of loaded cylinder for the pilot hole of loaded cylinder
It is identical, not described in detail herein.
Each embodiment in this specification is described in a progressive manner, the highlights of each of the examples are with other
The difference of embodiment, the same or similar parts in each embodiment may refer to each other.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
Various modifications to these embodiments will be readily apparent to those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, of the invention
It is not intended to be limited to the embodiments shown herein, and is to fit to and the principles and novel features disclosed herein phase one
The widest scope of cause.
