Description

Technical Field

[0001] The utility model relates to the technical field of aviation drill bit processing, in particular to a fixture for fine processing of an alloy drill bit. Background Art

[0002] In the current field of high-precision machining, especially in important industrial fields such as aviation, automobiles, and precision manufacturing, alloy drills are widely used to process various types of high-hardness, high-strength metal materials and alloy materials due to their excellent hardness and wear resistance, such as titanium alloys, nickel-based superalloys, etc. These materials usually occupy key positions in aerospace vehicles, high-performance engines, and other high-demand industrial products. Especially in the aviation field, the application of alloy drills is particularly critical because they are often used for the processing of high-strength materials such as titanium alloys and high-temperature alloys. These materials are widely used in aircraft engines and structural components, requiring the drills to not only have extremely high durability, but also maintain extremely high processing accuracy. The processing accuracy of aircraft components is directly related to flight safety and performance.

[0003] However, traditional drill processing fixtures face multiple challenges in the processing of aviation materials. First, the high hardness and toughness of aviation alloys require that the fixtures must have a high degree of stability and deformation resistance. Second, the complex shapes and strict tolerances of aviation components require the fixtures to provide precise positioning and repeatability. Conventional fixtures currently on the market often cannot meet these fine processing requirements, resulting in low processing efficiency and easy processing errors, which affects the quality and reliability of the final product.

[0004] Developing a fixture specifically for the finishing of aviation alloy drills to address the shortcomings of traditional fixtures in aviation material processing is a key technical innovation to improve the level of aircraft material processing and ensure aircraft performance and safety. This new fixture needs to be targeted at the special needs of the aviation field and has ultra-high stability, precise fine-tuning mechanism, and fast and accurate positioning function to ensure that the alloy drill can maintain the optimal processing state under harsh working conditions. Therefore, it is very necessary to use a fixture for finishing alloy drills in the existing field of aviation drill processing technology. Utility Model Content
