Problems solved by technology

[0003] However, the traditional method has the following disadvantages: first, the honeycomb core-carbon tube assembly is a new type of part, due to the different properties of different materials, the traditional method has been unable to meet the processing requirements of the assembly; The parts need to be clamped and aligned, and the clamping and alignment need to be adjusted many times, which not only affects the processing efficiency of the parts, but also increases the labor intensity of the operators

Embodiment 1

[0039] A kind of processing method of honeycomb core-carbon tube assembly, such as figure 1 , figure 2 , Figure 4 As shown, it mainly includes the following steps:

[0040] Step S2: select the tool and parameters for rough machining of the carbon tube material, and then roughly machine the profile of the carbon tube area;

[0041] Step S3: Select the cutting tool and parameters for processing the honeycomb core material, and based on the rough-processed carbon tube area profile, rough-process the honeycomb core profile, and the margin of the rough-processed honeycomb core profile is higher than the rough-processed Carbon tube area profile.

[0042]The honeycomb core-carbon tube assembly of the present invention is embedded in the honeycomb core 1 by a plurality of carbon tubes 2. When the honeycomb core-carbon tube assembly is processed, the carbon tube material is initially processed to obtain a rough carbon tube area. profile; then based on the rough machining profile,...

Embodiment 2

[0045] This embodiment is further optimized on the basis of Embodiment 1, adopts the helical milling cutting method, uses the bottom teeth of the cutter for milling, and avoids the center position of the cutter from participating in the cutting. The present invention selects the part to be milled by the tool when rough machining the profile of the carbon tube area, and adopts the spiral milling cutting method at the same time, so that the processing of the honeycomb core-carbon tube assembly has higher precision, improves the processing quality and ensures the rough machining of carbon The normal progress of the pipe area profile.

[0046] Other parts of this embodiment are the same as those of Embodiment 1, so details are not repeated here.

Embodiment 3

[0048] This embodiment is further optimized on the basis of Embodiment 1. In step S3, based on the rough-processed carbon tube area profile, a honeycomb core is constructed along the 2 mm above the highest point of the carbon tube area profile in the normal direction of the honeycomb core profile. Rough machining datum plane; in the step S3, the honeycomb core profile is roughly machined by means of fixed axis and equal cutting width.

[0049] The present invention roughs the honeycomb core profile by rough machining the carbon tube area profile, and improves the processing quality of the rough process honeycomb core profile by controlling the processing direction and reference plane; It can be processed in a wide way to ensure the processing quality of the rough processed honeycomb core surface.

[0050] Other parts of this embodiment are the same as those of Embodiment 1, so details are not repeated here.

Abstract

The invention discloses a method for processing a honeycomb core-carbon tube assembly, which mainly includes the following steps: step S2: select the tool and parameters for rough machining of carbon tube materials, and then roughly process the profile of the carbon tube area; step S3: select the honeycomb core The cutting tool and parameters of material processing, and based on the rough-machined carbon tube area profile, rough-machine the honeycomb core profile, and the margin of the rough-machined honeycomb core profile is higher than the rough-machined carbon tube area profile. The present invention performs processing step by step according to different regions of materials, which makes up for the limitation of the adaptability of the tool itself to the cutting material in the processing process, and avoids the sudden change in the cutting process caused by the transition between different materials during the processing process, thereby Avoid the quality problems of honeycomb core-carbon tube assembly processing, shorten the preparation time for part processing, reduce the labor intensity of workers, and improve the processing quality and efficiency of parts.
