Description

Technical Field

[0001] The invention relates to the technical field of identification plate processing of aircraft engine casing parts, and in particular to a processing device and a processing method for special-shaped circular holes of aluminum identification plates. Background Art

[0002] Aluminum signage (such as Figure 1 As shown in the figure, they are very common in aircraft engine casing parts. They are often used for product identification of accessory casing parts. Such products are often randomly assembled, with large quantities and many types. Usually, the length of the aluminum identification plate is 90mm, the width is 50mm, and the thickness is 3mm.

[0003] When the identification plate is assembled on the accessory receiver, special-shaped circular holes need to be processed at the four corners of the identification plate. Since the material of the identification plate is thin, traditional processing uses three-axis CNC processing, which is performed by drilling and milling, which is neither economical nor efficient. In addition, alignment is required during processing, and a flat-mouth vise is required for alignment and clamping, which takes a long time and results in low processing efficiency. Summary of the invention

[0010] Preferably, the punch head, guide column, and angular positioning handle are integrally manufactured to form the punch head; the anti-mistake positioning block is milled and integrally formed with the cover plate. The punch head is integrally formed to ensure the coaxiality of the punch head, guide column, and angular positioning handle. The anti-mistake positioning block is integrally formed with the cover plate, and the anti-mistake positioning block and the cover plate are milled from the same plate, which is convenient for processing and manufacturing.

[0011] Preferably, the diameter of the angular positioning handle is larger than the diameter of the guide column, and an axial limiting surface is formed between the angular positioning handle and the guide column. When punching is performed, the axial limiting surface is used to limit the position of the punch descending in the vertical direction.
