Problems solved by technology

[0003] However, the traditional method has the following disadvantages: firstly, different part structures need to order different profile tooling, and it is necessary to ensure a one-to-one correspondence between parts and tooling, which will increase the production preparation cycle and processing costs of parts; secondly, use double-sided tape to hold parts Finally, it needs to be soaked in alcohol to separate the parts from the tooling, which increases the cost of auxiliary materials. At the same time, it is difficult to clean the tape on the tooling surface after processing, and the honeycomb core parts may be deformed after soaking in alcohol, which will affect the quality of the parts, thus affecting the new generation of aviation.

Embodiment 1

[0020] A method for processing honeycomb core parts based on boss holding, such as figure 1 As shown, the process boss 2 is set along the outline of the part 3, and the remaining process material 1 is connected to the part 3 through the process boss 2; the first surface profile 7 of the part 3 is processed, and the process platform is flush with the profile of the part 3; Then, when turning over the second surface profile 8, a pressing plate is set on the process boss 2 to fix the part 3 with the process boss 2 as a reference.

[0021] During the use of the present invention, qualified honeycomb core parts 3 can be processed without ordering special profile tooling, reducing the processing cost of parts 3; there is no need to use double-sided adhesive tape 4 to hold parts 3, which effectively shortens the parts 3 production preparation period during processing; no need to use alcohol to soak part 3, avoid deformation of part 3 after processing, and ensure the processing qualit...

Embodiment 2

[0023] This embodiment is optimized on the basis of Embodiment 1. After the surface processing of the part 3 is completed, the contour of the part 3 is finally processed, and the process boss 2 around the part 3 is removed. When the second surface profile 8 is turned over, a double-sided adhesive tape 4 is pasted on the process boss 2 .

[0024] After turning over, consider the problem of the connection strength of the boss on the thin side of part 3, and stick the adhesive tape on the thinner process boss 2 to enhance the strength of the boss connection.

[0025] Other parts of this embodiment are the same as those of Embodiment 1, so details are not repeated here.

Embodiment 3

[0027] The present embodiment optimizes on the basis of embodiment 1 or 2, mainly comprises the following steps:

[0028] Step S100: First, trim the blank of the part 3 to obtain the first surface processing positioning surface 5 and the turning surface processing positioning surface 6, and process the first surface of the part 3 based on the repaired first surface processing positioning surface 5 Surface 7, while milling the process boss 2 to be flush with the surface of the part 3, and plane milling the remaining process material 1 to the set thickness;

[0029] Step S200: Then, the part 3 is turned over to process the second surface profile 8, and the process surplus material 1 and the process boss 2 of the turned-over processing positioning surface 6 processed on the first surface are used as a benchmark, and the process surplus material 1, the process Double-sided adhesive tape 4 is pasted on the bonding surface of the boss 2 and the tooling, respectively, to complete the...

Abstract

The invention discloses a honeycomb core part machining method based on boss holding. The honeycomb core part machining method based on boss holding comprises the steps of arranging a false boss alongthe contour of a part; connecting a false excess material with the part through the false boss; machining a first surface profile of the part; enabling the false boss to be aligned with the profile of the part; and then machining a second surface profile on a turned-over surface; and with the process boss as reference, arranging a press plate on the process boss to fix the part. According to thehoneycomb core part machining method based on boss holding, a standard honeycomb core part can be machined without customizing a special profile tool so that the part machining cost is reduced; without using a double-face adhesive tape to fixedly hold the part, the production preparation period of the part during machining is effectively shortened; without using ethyl alcohol to soak the part, thedeformation of the part after being machined is avoided, and the part machining quality is guaranteed; and the part tool assembling and disassembling process is eliminated, the part production efficiency is enhanced, and the labor intensity of operation personnel is reduced.

Description

technical field [0001] The invention belongs to the technical field of processing honeycomb core parts, and in particular relates to a processing method for honeycomb core parts based on boss holding. Background technique [0002] With the development of aviation technology, the requirements of the new generation of aviation equipment are getting higher and higher, and honeycomb core parts have been widely used due to their unique properties. As an integral part of the new generation of aviation equipment, honeycomb core parts play a vital role in the development of the entire aviation equipment. At present, most honeycomb core parts are double-sided parts. When processing by traditional methods, the first side is usually positioned and processed by general-purpose flat tooling. After the part is turned over, it is necessary to customize the profile tooling according to the structural characteristics of the part. The profile is compared with the profile and profile of the t...
