A bearing cylinder and its processing technology

Abstract

The invention discloses a processing technology of a load-bearing cylinder. During processing, an installation section of an assembly hole is processed on an end face of the inner cylinder, the innercylinder is welded with an outer wall of a runner, the installation section of the assembly hole is sealed, and the assembly section of the assembly hole is processed. As that mount section is in communication with the lumen, Therefore, the positioning requirement of the mounting section is reduced, and when the mounting section is processed, the mounting section can be sealed, thereby blocking the communication between the mounting section and the inner cavity, preventing iron chips and other impurities from falling into the inner cavity, thereby fundamentally preventing the pollution of theinner cavity, and greatly reducing the safety hidden danger existing in the use process of the engine. The invention also discloses a load-bearing cylinder with the above-mentioned processing technology.

Description

technical field The invention relates to the technical field of engines, in particular to a processing technology of a load-bearing cylinder and a load-bearing cylinder adopting the processing technology. Background technique As shown in Figure 1, the load-bearing cylinder parts need to be ventilated, so they are welded through an outer wall of the flow channel 02 and an inner cylinder 01 during design, and an inner cavity is left between the two to ensure that the air flow can pass through smoothly . In the actual processing process, the three assembly holes 03 on the large end face connected to the inner cavity need to be positioned with other components during subsequent assembly, so there is a requirement for position accuracy, so the three assembly holes on the end face 03 must be processed after the outer wall of the flow channel 02 and the inner cylinder 01 are welded. However, it can be seen from the sectional view of the assembly hole of the part (Fig. 2) that th...

Problems solved by technology

However, it can be seen from the sectional view of the assembly hole of the part (Fig. 2) that the assembly hole 03 is directly connected to the inner cavity of the part, and the assembly hole 03 is processed by digital milling, so it is inevitable that there will be Iron filings will enter the inner cavity of the part along with the coolant, and it is difficult to remove it later, resulting in excess residue inside the part

This type of part is currently a relatively critical part in the development of new engines. It has previously occurred that this type of part has caused the entire part to be re-disassembled due to the existence of excess material in the inner cavity of the part, which has caused major safety hazards during the use of the engine.
