Description

Technical Field

[0001] The utility model relates to the technical field of NdFeB processing devices, in particular to a four-station variable-angle chamfering machine for NdFeB magnets. Background Art

[0002] NdFeB magnets are tetragonal crystals formed by neodymium, iron and boron. The magnetic energy product of this magnet is greater than that of samarium cobalt magnets. Chamfering is the most common and widely used processing method for all NdFeB magnetic materials.

[0003] A Chinese patent (publication number: CN219987098 U) discloses a four-station variable angle chamfering machine for NdFeB magnets. The electric telescopic rod is started to move the clamping plate downward to clamp and fix the magnet. Then, the motor four can be started to rotate the surface of the rotating seat and the processing seat, so that the magnet can be rotated during chamfering to perform chamfering at various positions, thereby increasing the adjustability and rotational performance during the chamfering process. However, when chamfering, the chamfering machine cannot make the grinding head move along a straight line toward the NdFeB magnet to be processed, which easily causes the NdFeB magnet to deviate during the chamfering process, resulting in a decrease in grinding accuracy and affecting product quality. In addition, the chamfering angle cannot be freely adjusted, which affects the convenience of the chamfering machine during use and thus affects the processing efficiency.

[0004] Based on this, a four-station variable-angle chamfering machine for NdFeB magnets is now provided, which can eliminate the disadvantages of existing chamfering machines. Utility Model Content
