Problems solved by technology

This method has the following problems: 1. Repeated setback repairs must be made during skin assembly
2. After the skin is assembled, there may be inaccurate positioning between the clamps, which makes it difficult for the product to ensure the position accuracy of the launch holes between the clamps, which affects the assembly of the launch tube
3. It is difficult to ensure the accuracy of the distance between the rear clamp ring and the disc, which will eventually affect the final assembly size of the product

Embodiment Construction

[0018] Below in conjunction with accompanying drawing, the present invention will be further described:

[0019] An assembly device for a pre-ignition fairing, comprising the following components: a base 1, a threaded rod 2, a stop screw 3, a limit bush 4, a limit block 5, a positioning pin 6, a bush 7, and a small positioning shaft 8. Positioning shaft 9, latch 10, pad 11, pressure plate 12, step nut 13, handle 14, pressure plate assembly 15, skin assembly; pressure plate assembly 15 includes flat pressure plate, screw, stud bolt, nut; skin assembly is Manufactured by pre-installing the center clip and rear clip assemblies and the front clip and front cone assemblies within the skin.

[0020] The main implementation process: first place the base of the device on the working platform, start to guide the center hole in the disc through the threaded rod 2, and use a positioning shaft 9 and a small positioning shaft 8 to position it, and stick to the upper surface of the base 1 ...

Abstract

The invention belongs to the technical field of machinery manufacturing and particularly relates to an assembling device for the nose cowl of a rocket launcher. An assembling device for the nose cowlof a rocket launcher comprises a base, a threaded connecting rod, cylindrical pins for press plate assemblies, stop screws, a bushing, a cushion block, a step nut, a bolt, a limit bushing, limit blocks, a small positioning shaft, positioning shafts, a press plate and handles, wherein each press plate assembly comprises a flat pressure plate, a stop screw, a stud and a nut. The assembling device provided by the invention is simple in structure and convenient to operate, well solves the problem about ensuring the position accuracy of a launching hole between clamping rings, ensures the distanceand parallelism between a rear clamping ring in a skin assembly and a disc and does not need to repair or file a skin. The structure applies to the assembling of devices similar to the nose cowl of the rocket launcher.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to an assembly device for a front fairing of a rocket launcher. Background technique [0002] The front fairing of the rocket launcher is an important part of the rocket launcher system of the aircraft pylon. It is a typical metal frame thin shell structure and is mainly used for aerodynamic rectification and reducing flight resistance. The front fairing is mainly composed of a front cone, a central tube, a front clamp ring, a middle clamp ring, a rear clamp ring, a disc, a central screw, a skin, and the like to form a conical shell. For the assembly of products with this structure, the following methods are mainly used now: connect the front cone and the front clamping ring with the front reinforcing bar fixing screws, connect the middle clamping ring and the rear clamping ring with the rear reinforcing bar fixing screws, and then pass the center screw ...
