Special clamp for thin and long cylindrical thin wall assembly

Abstract

The invention provides a special clamp for a thin and long cylindrical thin wall assembly and belongs to the field of mechanical manufacturing. By means of the clamp, the functions of locating and clamping the assembly when milling is conducted on the specific positions of the symmetrical faces of a tail fin on the outer circular face of the thin and long cylindrical thin wall assembly in the axis direction of the assembly can be achieved. The special clamp is composed of a front clamp body, a rear clamp body and a clamp base, the clamp base is composed of a base body and a locating key, the front clamp body is composed of a front V-shaped block, a front baffle, a front press plate, a front stud and a front mandrel, and the rear clamp body is composed of a rear V-shaped block, a rear baffle, a rear press plate, a rear stud and a rear mandrel. The special clamp for the thin and long cylindrical thin wall assembly saves time for manual measuring and locating, ensures locating precision, avoids damage to the thin and long cylindrical thin wall assembly caused during clamping and machining, increases machining efficiency, and ensures machining precision.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and relates to a special fixture applied to a slender cylindrical thin-walled assembly. The positioning and clamping function of the assembly during milling. Background technique [0002] With the continuous improvement of the status of aircraft combat capability in the development of air military power, the performance and stability of aircraft drops have received more and more attention. The aircraft drop is a slender cylindrical thin-wall assembly with complex shape, slender parts and thin walls, and poor rigidity of the cylinder section. The tail of the assembly has four uniformly distributed empennages. When conducting research on this slender cylindrical thin-walled assembly, especially when conducting the scaled-down drop experiment of aircraft drops, it is necessary to carry out milling along the axis of the assembly at a specific position on the outer circular surface of the asse...
