Abstract:To overcome the shortcomings of large power consumption of lifting electromagnet, green energy saving lifting permanent magnet has become a hotspot in recent years. Based on the analysis and comparison of the performance difference between the lifting permanent magnet and the lifting electromagnet, we design a kind of anti-inclined lifting permanent magnet which has the ability to lifting the workpiece placed level or inclined. First, the structure design of permanent magnet ferromagnetic circuit is completed, and the size of permanent magnet and magnetizer of fixed magnetic system and rotating magnetic system is calculated, and the residual magnetic field strength under the unloading state of the design is analyzed. Then, according to the characteristics of the rotating magnetic system, the anti-inclined drive mechanism is designed, consisting of two sets of ratchet rotating arm mechanism with opposite rotation direction and bevel gear reversing mechanism, so as to ensure that at least one set can drive the rotating magnetic system to hold and release workpiece. The problem that single rotating arm lifting permanent magnet cannot lift the inclined workpiece is solved.
