Problems solved by technology

[0006] When fiber-reinforced resin is used in the fuselage or body of an aircraft, automobile, or their constituent elements, it is necessary to perform drilling processing for bolts and the like to pass through the connecting parts of the constituent elements, but when using a drill, etc. In the case of a general-purpose drilling device in which a tool is attached to a shaft and only a drill bit is rotated, when drilling a fiber-reinforced resin (for example, a thermosetting resin containing carbon fiber, glass fiber, etc. There are problems in that significant heat generation due to frictional resistance in the drilling process occurs, the smoothness of the processed surface of the hole drilled with fiber-reinforced resin, etc. is significantly deteriorated, and the life of drilling tools such as drills become extremely short

Embodiment Construction

[0037] Next, a first embodiment of the present invention will be described in detail with reference to the drawings.

[0038] Such as figure 1 As shown, the main structure of the eccentric rotation drive mechanism 16 in the drilling device of this embodiment includes: a cylindrical body (hereinafter referred to as "inner cylinder") 20, which is built in by the first rotating shaft part 3 The air-driven part that air motor 15 (such as turbine etc.) constitutes, makes drilling such as end mill cutter 1 around the axis of rotation shaft part 3 ( Figure 5 C1) rotates on its own axis while around the axis of the eccentric cylinder ( Figure 5 C2) revolution; the first deceleration member 14-1 [such as a harmonic drive (registered trademark)], which is connected with the rotation shaft portion 3 extending from the holder 2 that holds the above-mentioned drilling tool; the eccentric cylindrical body (hereinafter referred to as "outer cylinder") 19, which is connected to the output...

Abstract

An eccentric rotation drive mechanism (16) which is rotatably contained in a first slide container (17-1) is provided with an outer cylinder (19), an internal cylinder (20) which is housed at eccentric position thereof and a first air motor (15) contained therein. One end of a rotation shaft portion (3), that is, a shaft of the first air motor (15) is fastened to a hole making tool (1), the other end of which is coupled to the end surface of the outer cylinder (19) through a first reduction device (14-1). The rotation of the air motor (15) makes the hole making tool (1) rotate and revolve and simultaneously the rotation of a second air motor (24) mounted outside of a casing (7) is transmitted to a ball screw (12a) through a rotation transmission device inside of a second slide container (17-2) to advance and retreat a feed drive mechanism (13) so as to machine a hole in a workpiece (5).

Description

technical field [0001] The present invention relates to a drilling device capable of drilling a workpiece such as a fiber-reinforced resin and a laminate thereof with high precision using a drilling tool such as an end mill. Background technique [0002] Recently, in order to reduce the weight of aircraft fuselages and automobile and other vehicle bodies, fiber-reinforced resin (FRP) has been used to form the fuselage itself, the body itself, or the components of the fuselage and the body. Regarding this kind of fiber-reinforced resin, there are thermosetting resins containing carbon fibers as reinforcing fibers (CFRP), thermosetting resins containing glass fibers as reinforcing fibers (GFRP), or containing aromatic polyamyl, aromatic polysulfone, Various types of such fiber-reinforced resins, such as heat-resistant synthetic resin fibers such as aromatic polyimide as reinforcing fibers, such as thermosetting resins, are generally known to be constructed by laminating a plur...
