Embodiment Construction

[0023] This embodiment is a solid rocket motor liner forming rotary tooling. The liner forming rotary tooling 3 is lath-shaped, and at both ends of the liner forming rotary tooling there are shell clips 4 bent toward the cylindrical surface of the outer surface of the shell, such as figure 2 shown. The axial length of the shell clamping plate is 25mm. Both the inner surface and the outer surface of the clamping plate are arc surfaces, and the radius R3 of the arc surface is the same as the radius of the outer peripheral surface of the housing 7 . Two housing skirt frame installation holes 1 with a diameter of 12 mm and two universal joint installation through holes 2 with a diameter of 10 mm are distributed on the tooling, and the two housing skirt frame installation holes are respectively located at the The seam covers the two ends of the frock so that the two universal joint installation through holes are located between the two housing skirt frame installation holes. In...

Abstract

The invention relates to a solid rocket engine lining forming rotating tool. The lining forming rotating tool is strip-shaped, and both ends of the lining forming rotating tool are provided with shellclamping plates bent towards the cylindrical surface of the outer surface of a shell. The inner surfaces and the outer surfaces of the shell clamping plates are cambered surfaces with the same radiusas the outer circumferential surface of the shell. Two shell skirt frame mounting holes and two universal joint mounting through holes are distributed in the length direction of the lining forming rotating tool, the two shell skirt frame mounting holes are positioned at two ends of the lining forming rotating tool correspondingly, and the two universal joint mounting through holes are positionedbetween the two shell skirt frame mounting holes. The tool has a simple structure, convenient installation, good quality consistency of products produced in the same batch and high efficiency, obtained sprayed solid rocket engine lining with a large slenderness ratio is a spray coating, and the thickness of the lining is uniform; and on the premise of ensuring that the tool meets normal use strength, the weight of the tool is reduced and installation is convenient.

Description

technical field [0001] The invention relates to the field of solid rocket motors, in particular to a rotating tooling for cladding shells when spraying linings of solid rocket motors with large slenderness ratios. [0002] technical background [0003] With the development of my country's solid rocket motor technology and the needs of national defense construction, the production tasks and quantity of tactical motors continue to increase, which puts forward new requirements for equipment and tooling in the production process. A certain model has a diameter of 300mm and a length of 3200mm; before this type of liner forming process, there were only 3 rounds of one set of products. Currently, one set of products is 10 rounds during the lining forming process. The loading and unloading of a large number of lining forming rotary tools is time-consuming and labor-intensive. It takes 3 people and 3 hours to complete the installation of this type of lining rotary tooling; and the rot...
