Problems solved by technology

However, if this device is applied to magnet processing, on the one hand, the clamp 1 of the tightening mechanism in direct contact with the magnet is made of hard material, which will easily cause the rare earth hole tube magnet to be partially crushed by force.
On the other hand, the elastic body is far away from the workpiece. Considering the mass inertia of the tightening mechanism and the friction between each other, the effect of absorbing the vibration exerted by the grinding rod on the workpiece is limited.

Abstract

The invention provides machining equipment for the inner circle of a circular tube magnet. The machining equipment comprises a base, wherein a rotation mechanism is installed on the left part of the base; a drive table capable of moving on the three coordinates X, Y and Z is installed on the right part of the base; the centre of the rotation mechanism is sleeved with a chuck with a locking mechanism, and the chuck is used for clamping the hole tube magnet for machining; a ring of elastomers is added around the hole tube magnet; a high-speed rotation mechanism is arranged on the drive table; and a detachable elastic grinding head used for avoiding the shock of the hole tube magnet during grinding machining is installed at the centre of the high-speed rotation mechanism. According to the machining equipment provided by the invention, breakage in a machining process of the thin-wall hole tube magnets is avoided, so that the yield is increased; and on the other hand, the phenomenon of large heads and small heads of the inner holes of hole tubes is avoided, and the inner hole machining accuracy for the products is improved.

Description

technical field [0001] The invention belongs to the field of processing rare earth permanent magnet NdFeB materials, and in particular relates to a method and equipment for processing the inner circle of a circular tube magnet. Background technique [0002] One of the most important application fields of rare earth permanent magnet NdFeB materials is an important basic material supporting the modern electronic information industry. , as large as automobiles, generators, medical instruments, etc., permanent magnet materials are ubiquitous. Rare earth permanent magnets often have different shapes due to different application environments, such as tiles, straight bars, rings, round tubes or various special-shaped parts, etc. Among them, the market demand for permanent magnets with longitudinal through holes (for example, cylindrical or annular permanent magnets) is very large. For permanent magnets of this shape, the processing method is different according to the shape of th...
