Problems solved by technology

[0002] In the aviation assembly process, various types of riveting are often used to connect the skin and the skeleton. In the riveting process, it is often necessary to use the socket head for the top riveting work. According to the different spatial positions of the riveting, the straight socket head and the curved socket head are selected for auxiliary processing. The two kinds of cornbreads are all one-piece structure. For the angle and length of the bent cornbread in places with large skin curvature and narrow space, the expected use effect cannot be achieved, which affects the production progress and the surface quality of skin processing.
[0003] For the riveting of the new snake-shaped large-curvature skin, the existing straight and curved sockets are used. Due to the long connecting rods of the sockets, the transmission of working force is poor, and it is easy to cause bumps on the skin surface around the installation of the rivets. At the same time, it cannot be realized. The narrow space and the skin connection work with large curvature make the assembly work a bottleneck and the production cannot be carried out

Embodiment Construction

[0020] A universal detachable nest head, the structure of which is as follows figure 1 As shown, it adopts a split structure, which is composed of the working part 1 and the connecting rod part 2 of the steamer;

[0021] The outer surface of the working part 1 is stepped, such as Figure 2-5 As shown, the size of the large end of the step table is φ24mm, the size of the small end is φ22mm, and the total length is 20mm. Its left end face is a working surface 11; the inside of the working part is a hollow structure, and the inner end face of the hollow structure is in the form of an inner boss 12, which is used to limit the extraction of the socket connecting part from the working part of the socket; the outer surface of the working part An inclined plane 13 is milled out on the surface, the angle of the inclined plane 13 is 19°, and the distance from the small end is 15mm, so that the connecting rod part of the cornbread can be easily installed into the working part of the cor...

Abstract

The invention relates to a universal detachable head and a using method thereof. The detachable head which is in a split structure is composed of a working part and a connecting rod part; the outer surface of the working part is step-shaped, and the left end face of the working part is a working surface; the inner part of the working part is a hollow structure, the inner end face of which is in a form of an inner boss for limiting a head connecting part which is pulled out from the working part of the head; a tapered plane is milled on the outer surface of the working part for mounting the connecting rod part of the head; the connecting rod part is composed of a head part, a boss part and a tail part; the head part end face of the connecting rod part is an arc-shaped face, the arc-shaped face is in contact with the bottom face of the head working part, the boss part is positioned in the middle of the connecting rod part for limitation when a riveter is fixed, and the tail part of the connecting rod part is connected to the riveter. By using the universal detachable head, riveting work which is great in degree of curve and narrow in space in any positions can be performed, so that the problem that a conventional head cannot satisfy the production needs is solved.

Description

technical field [0001] The invention relates to a novel universal detachable nest head and a using method thereof, which are suitable for skin curvature and riveting processing in narrow spaces. Background technique [0002] In the aviation assembly process, various types of riveting are often used to connect the skin and the skeleton. In the riveting process, it is often necessary to use the socket head for the top riveting work. According to the different spatial positions of the riveting, the straight socket head and the curved socket head are selected for auxiliary processing. The two kinds of cornbreads are of one-piece structure. For the angle and length of the bent cornbread in places with large skin curvature and narrow space, the expected use effect cannot be achieved, which affects the production progress and the surface quality of skin processing. [0003] For the riveting of the new snake-shaped large-curvature skin, the existing straight and curved sockets are u...
