Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0038] refer to figure 1 with image 3 , a boring machine fixture with oblique openings in a composite compartment, including a positioning plate 1. One end of the positioning disc 1 is in interference fit with the steel sleeve 4 . The inside of the upper end surface of the positioning disc 1 is interference fit with two cylindrical positioning pins 3 . Two pressing plates 5 are installed on the upper end surface of the positioning disc 1 . Two lifting bolts 2 are installed on both sides of the clip body 1 .

[0039]Open the oblique opening of 40 ° in composite cabin section 6, its process is as follows:

[0040] (1) Calculate the offset distance L value of the boring machine tool: curve equation Y=300(X / 1800)^0.55(930≤X≤1800), opening position b=100, opening angle 2θ=40°, chord length at the opening 2a=120±0.1, find: tool offset distanc...

Abstract

The invention discloses a boring mill clamp for forming an inner oblique opening in a composite cabin section and a method for forming the inner oblique opening in the composite cabin section, and belongs to the technical field of machinery processing. The boring mill clamp comprises a positioning disc, one end of he positioning disc is provided with a steel cover; a positioning pin is mounted in the upper end face of the positioning disc and a press plate is mounted on the upper end face of the positioning disc. The boring mill clamp for forming the inner oblique opening in the composite cabin section and the method for forming the inner oblique opening in the composite cabin section can improve the precision of the inner oblique opening in the composite cabin section.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a method for opening oblique openings in composite cabin sections. Background technique [0002] The composite compartment is generally composed of various compartments with different functions. During the flight, it will rub against the atmosphere, and the outer surface will generate a lot of heat. In order to ensure the stability of the performance of the product during the flight, the surface is heat-resistant Heat insulation becomes more important, so the general cabin section is made of metal parts (such as aluminum alloy) as the structural part shell, and various non-metallic composite materials have low density, light weight, and good heat resistance and heat insulation performance. , suits and other methods are covered on the metal shell to form a composite structural cabin section in which multiple materials are superimposed. In order to instal...
