Tooling for wire-cut locking ring groove and method of use thereof

Abstract

The invention provides a tooling for a wire-cut lock ring groove, which includes a tooling cover, an upper tooling plug and a lower tooling plug. The tooling cover is provided with a slot through which at least one end is connected. The connected upper grooved part and the inner grooved part connected with the upper grooved part, the section of the inner grooved part is slightly larger than that of the lock ring in the horizontal direction when the lock ring to be processed is placed at an angle θ with the horizontal direction. The projection of the upper tooling plug and the lower tooling plug has at least one end that can enter the tooling sleeve through the inner slot, and the end surface of the upper tooling plug and the lower tooling plug that enters the tooling sleeve is a slope, so The included angle between the slope and the horizontal direction is θ, where θ is the inclination angle of the lock ring groove. The invention can simultaneously process a plurality of locking rings by means of wire cutting, and has high processing efficiency and good stability.

Description

technical field [0001] The invention belongs to the technical field of lock ring groove processing, and in particular relates to a wire-cut lock ring groove tooling and a use method thereof. Background technique [0002] Blind rivets with metal lock rings are in great demand on aircraft. The metal lock rings have a small shape, an outer diameter of 3-9mm, a small width, a thin arm, and a narrow inclined groove on the lock ring. The commonly used processing method for the lock ring is to make it into a ring without opening ( figure 1 ), and then use milling or wire cutting to process the inclined groove, wherein the angle between the lock ring groove and the direction of the central axis of the lock ring is the inclination angle of the lock ring groove, which can be expressed by θ ( figure 2 ). Due to the small shape of the metal lock ring and the requirement for the inclination angle, a special clamping tool is required to improve the processing efficiency. However, the ...

AI Technical Summary

Problems solved by technology

However, the existing special clamping tool can only clamp one lock ring at a time, and the processing efficiency is low

In addition, if milling is used to produce burrs, an additional deburring process is required, and because the size of the lock ring is small, it is difficult to deburr and the efficiency is low
