AI Technical Summary
In the existing technology, the processing efficiency of the oil slinger holes on the oil slinger plate is low, and the consistency of the angle is difficult to guarantee. In particular, when different tilt angle holes are required, the adjustment is cumbersome and the accuracy depends on the operator, which affects the performance and service life of the combustion chamber.
An improved oil-throwing hole processing device with a baffled combustion chamber is used. Multiple drilling modules are arranged in a circumferential array on the core ring. Combined with the adjustment unit and clamping module, multiple holes can be processed simultaneously and the angle can be adjusted in a consistent manner. The clamping process is simple. During the drilling process, the impact force of the drill bit is buffered by the compensation spring, and the adjustment screw drives the angle adjustment accurately.
It significantly improves the processing efficiency and precision of the oil slinger, ensures that all hole angles are consistent, reduces angle errors, enhances fuel atomization and combustion chamber performance, and reduces costs and time consumption.
