High-precision adjustable auxiliary machining equipment for neodymium-iron-boron magnet

Abstract

The high-precision adjustable auxiliary machining equipment comprises a main body bin, first lower mounting rollers are symmetrically arranged in the middle positions of the two sides in the main body bin, and second lower mounting rollers are symmetrically arranged at the bottoms of the ends, close to the first lower mounting rollers, of the two sides in the main body bin; and two groups of second electric lifting rods are mounted at one end, close to the first lower mounting roller, of the top in the main body bin. A servo motor is controlled to drive an arc-shaped material guide plate to rotate by 90 degrees anticlockwise, then a first electric push rod can be controlled to extend, and a material pushing pipe is used for pushing a circular ring neodymium-iron-boron magnet between two groups of first lower mounting rollers to move towards one end close to a fixed plate until the first group of circular ring neodymium-iron-boron magnets are overturned and fall into the arc-shaped material guide plate; and at the moment, the unchamfered ends of the first group of circular neodymium-iron-boron magnets face the second group of polishing heads, so that the automatic direction adjustment of the circular neodymium-iron-boron magnets by the equipment is realized.

Description

technical field [0001] The invention relates to the technical field of auxiliary processing equipment for NdFeB magnets, in particular to a high-precision adjustable auxiliary processing equipment for NdFeB magnets. Background technique [0002] NdFeB magnets are tetragonal crystals formed of neodymium, iron, and boron. In 1982, Masato Sagawa discovered neodymium magnets. The magnetic energy product of this magnet was greater than that of samarium cobalt magnets, and it was the material with the largest magnetic energy product in the world at that time. , and successfully developed the powder metallurgy method. General Motors successfully developed the spin-spray smelting method, which can produce NdFeB magnets. This kind of magnet is the permanent magnet that is second only to the absolute zero holmium magnet, and it is also the most commonly used rare earth magnet. NdFeB magnets are widely used in electronic products, and circular NdFeB magnets are one of the commonly used...

Problems solved by technology

[0003] At present, when chamfering the inner or outer corners of the ring-shaped NdFeB magnets, it is often necessary for the operator to manually exchange the two ends of the ring NdFeB magnets for grinding, and after changing the positions of the two ends of the ring NdFeB magnets, the device is still only It can chamfer a group of circular NdFeB magnets, but cannot chamfer two sets of circular NdFeB magnets at the same time; and the current auxiliary processing equipment for circular NdFeB magnets still requires operators to manually process Remove the good ring NdFeB magnets and replace them with a new set of ring NdFeB magnets. During the process of replacing the ring NdFeB magnets, the operator's hands are relatively close to the chamfering and grinding structure of the device. , it is easy to cause accidental damage, and it is impossible to automatically replenish the non-chamfered circular NdFeB magnets into the processing equipment; at the same time, the current auxiliary processing equipment of the circular NdFeB magnets is grinding the circular NdFeB magnets of different calibers. When the magnet is used, it is necessary to replace the corresponding fixed structure, which is very inconvenient. It is impossible to make the auxiliary processing equipment suitable for more caliber ring NdFeB magnets, and it is also impossible to automatically move the position of the ring NdFeB magnet to the chamfer The corresponding chamfer of the device
