Embodiment Construction

[0031] The following will be combined with Figure 1-8 The technical solution of the present invention is described in detail.

[0032] like Figure 1-6 As shown, this embodiment provides a follow-up adjustable front and back edge reaming tool for carbon fiber composite materials. Follow-up adjustable blade 4, gasket 5, anti-loosening nut 6, installation groove 7, cavity 8, anti-loosening threaded column 9, vent hole 10.

[0033] The structure of the lower part of the neck 3 near the handle 1 is similar to that of an ordinary straight groove six-blade reamer. The neck 3 is designed with a reamer blade 2, and the cutting edge of the reamer blade 2 is designed in the form of a positive edge.

[0034] There are 6 reamer blades 2 in total and are integrated with the knife neck 3 and cannot be disassembled.

[0035] The knife neck 3 is provided with six installation grooves 7 at the rear end, and the structure is in the shape of an inverted "T", which is used to install the foll...

Abstract

The invention relates to a follow-up adjustable positive and negative edge reaming tool for carbon fiber composite materials, comprising a handle (1), a positive-edge reaming blade (2), a knife neck (3), and a follow-up adjustable cutting edge (4). ), washer (5), locking nut (6), mounting groove (7), cavity (8), anti-loosening threaded post (9), air hole (10), set near the lower end of the shank (1) The knife neck (3), a reamer blade (2) is arranged on the knife neck (3), and the cutting edge of the reamer blade (2) is designed in the form of a positive edge; the knife neck (3) is provided with a number of installation grooves (7) at the tail end ) to install the follow-up adjustable blade (4), the follow-up adjustable blade (4) can perform up and down telescopic movement in the installation groove (7) in the form of a sliding pair; the present invention also relates to carbon fiber composite materials According to the processing method, the invention can effectively suppress the damage defects such as tearing and delamination of the fiber layer at the hole outlet of the carbon fiber composite material during the reaming process.

Description

technical field [0001] The invention belongs to the machining technology, and in particular relates to a follow-up adjustable front and back edge reaming tool for carbon fiber composite materials and a processing method. Background technique [0002] Carbon fiber composite materials have been widely used in aviation, aerospace, automobile and other fields because of their excellent thermal properties such as high specific strength, good fatigue resistance, and good wear resistance. Up to now, rivets and bolts are still the main connection methods between carbon fiber composite components, and a large number of assembly holes are required for mechanical connection. For example, the amount of carbon fiber composite materials used in my country's domestic large aircraft C919 accounts for about 13%, and the number of holes in the whole machine is as high as tens of thousands. [0003] At present, the carbon fiber composite material mechanical drilling process requires the repla...
