Embodiment Construction

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. It should be noted that, in the case of no conflict, the embodiments and the features in the embodiments of the present invention can be combined with each other, and the described embodiments are only some of the embodiments of the present invention, but not all of the embodiments.

[0031] 1. Specific implementation mode 1, see Figure 1-7 To illustrate this embodiment, the sunken stepped coaxial assembly tool includes stepped positioning bolts 3 and pins 2 , and the pins 2 are coaxially positioned by the stepped positioning bolts 3 after sinking into the installation position. The positioning of the column pin 2 sinking into the rear axial hole is corrected by screwing the stepped positioning bolt 3 into the threaded hole of the column pin 2 .

[0032] The stepped positioning ...

Abstract

The invention provides a sinking step type coaxial assembly tool and a using method thereof, and belongs to the field of fiber composite material processing. The coaxial problem of the axial hole of the submerged pin and a matched part is solved. The sinking step type coaxial assembly tool is used for guaranteeing the radial sinking perpendicularity and the centripetal degree of the pin in a fiber composite material launching device product, the parallelism of an axial threaded hole and the axis of the fiber composite material launching device product after the pin is sunk, and the axial threaded hole and a transition hole of the fiber composite material launching device product are coaxial; and finally, the assembly precision of the matching surface is realized, and the secondary installation matching precision of the metal blanking cap and the fiber composite material launching device product is completed. The product formed through the assembling method is stable in precision, the one-time installation rate of the matching face is high, the problems that a traditional machining method is not easy to position, difficult to operate, poor in coaxiality and low in efficiency are solved, and the coaxial problem of the axial hole of the submerged pin and the matching part is effectively solved.

Description

technical field [0001] The invention belongs to the field of fiber composite material processing, and in particular relates to a submerged stepped coaxial assembly tool and a method for using the same. Background technique [0002] Due to its excellent characteristics of high strength, high modulus and light weight, fiber composite materials are used more and more in cutting-edge fields such as aerospace. During the use of fiber composite products, they are often used in conjunction with metal parts to meet dimensional accuracy and stability, which puts forward requirements on how to ensure the assembly accuracy between metal parts and composite parts. [0003] At present, most of the launch protection devices are made of fiber composite materials, which has largely realized the lightweight of the launch protection devices. However, the assemblability of fiber composite products is not as good as that of metal materials, especially for parts that require threaded connections...
