Clamp for magnetized magnetic ring for linear cutting and application method thereof

Abstract

The invention discloses a clamp for a magnetized magnetic ring for linear cutting and an application method thereof. The clamp comprises a main clamp (1) and an auxiliary limiting block (2). A through hole (3) is arranged in the main clamp (1). The diameter of the through hole (3) is matched with the external diameter of the magnetized magnetic ring (9) to be cut. A groove (4) communicated with the through hole (3) is arranged in the inner wall on one side of the main clamp (1). A cut (5) is arranged on one side opposite to the groove (4) in the main clamp (1). The width of the cut (5) is no smaller than that of a first opening of the magnetized magnetic ring (9). The width of the groove (4) is no smaller than that of a second opening of the magnetized magnetic ring (9). The auxiliary limiting block (2) comprises a boss (6), the width of which is matched with that of the first opening of the magnetized magnetic ring (9).The application method of the clamp comprises the step of splitting the magnetized magnetic ring and the step of opening and then splitting the magnetized magnetic ring. The clamp for the magnetized magnetic ring for linear cutting and the application method thereof help to ensure that splitting dimensional deviation of the magnetized magnetic ring is smaller than 0.05 mm and opening dimensional deviation thereof is smaller than 0.03mm.

Description

technical field [0001] The invention relates to a jig for wire cutting and a using method thereof, in particular to a jig for wire cutting with a magnetic ring and a using method thereof. Background technique [0002] The magnetic ring used for traveling wave tubes, the magnetic system is composed of a dozen to dozens of rare earth permanent magnet rings, each magnetic ring must be cut in half or opened and cut in half before it can be assembled, the cutting size of the magnetic ring needs to be accurate, two A half-ring cannot exceed 0.1mm. Before the magnetic ring is cut, it is saturated and magnetized by the magnetizer to make the magnetic performance meet the requirements of use. The cutting accuracy of the magnetic ring will directly affect the use effect of the magnetic ring. In the prior art, a right-angled triangular iron clamp is used to fix the magnetic ring with a magnetic ring in half or with an opening, such as figure 1 , figure 2 shown. Although the clamp...

AI Technical Summary

Problems solved by technology

Although the clamps of the prior art have good versatility, the fixing effect is relatively poor. When the strong magnetic ring is split or opened, two poles that repel each other will be formed at the gap that is cut first, and there is a gap between the two poles that repel each other. Strong reverse force, this force will affect the fixing of the part after cutting, so in the case of poor fixing effect, the magnetic ring cannot be cut perfectly, and the accuracy of the magnetic ring cannot be guaranteed, especially in the opening And it is more difficult to ensure the accuracy of the magnetic ring when the magnetic ring is cut in half
