Abstract

The invention relates to a processing method of a weakly rigid I-shaped component, and belongs to the technical field of machining, in particular to a processing method of a long and thin thin-walledhigh-strength component; and the goal of performing anti-deformation efficient processing on the weakly rigid I-shaped component is achieved by employing a combined processing measure of component rigidity-gradient steady-state processing and minimum control over cutting stress. The employed technical solution is that the processing method of the weakly rigid I-shaped component comprises the following steps of a clamping step: clamping with a double-parallel jaw vice; and a processing step: processing the weakly rigid I-shaped component in sequence of processing from two ends to the center byemploying a processing way of high-speed milling; moreover, when a groove in an I-shaped structure is processed, two technology grooves are firstly milled at a high speed; and the technology grooves are the two end parts of the groove in the I-shaped structure. The processing method disclosed by the invention is used for processing the weakly rigid I-shaped component.

Description

technical field [0001] The invention relates to a processing method of a weakly rigid I-shaped member, which belongs to the technical field of mechanical processing, and in particular relates to a processing method of a slender, thin-walled and high-strength member. Background technique [0002] like Figure 1-Figure 3 As shown, a weakly rigid I-shaped member is elongated as a whole, with flat lugs at both ends. There are steps on the lugs, and arc-shaped lug grooves on the steps. The two lugs are connected to the middle body of the member. Each part is provided with a lug reinforcing rib, and the cross-section of the body part between the two lug reinforcing ribs is I-shaped, and there are multiple lightening holes on the web. The specific structural parameters are shown in the table below. [0003] Table 1 Structural parameters of a weakly rigid I-shaped member [0004] [0005] It can be seen from Table 1 that the characteristics of this component are: [0006] 1. T...
