Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail: the present embodiment is implemented under premised on technical solution of the present invention, gives detailed enforcement mode, but protection scope of the present invention is not limited to following embodiment.
As shown in Fig. 1 ~ Fig. 7, a kind of two-phase permanent magnet tracking frictional vibration performer involved by the present embodiment, comprises mover assembly and stator module, and described mover assembly comprises mover center post 1 and rotor permanent magnet 2, described stator module comprises stator upper end cover spring 3, stator lower end cover spring 4, stator core 5, stator winding 6, stator shell 7, joint nut 8, fitting nut 9 and stator core support 10, for concentric(al) circles is arranged between described mover center post 1 and stator shell 7, described stator upper end cover spring 3 is arranged on the top of mover center post 1 and stator shell 7, described stator lower end cover spring 4 is arranged on the bottom of mover center post 1 and stator shell 7, the mover center post 1 of stator upper end cover spring 3 upper end is provided with fitting nut 9, the mover center post 1 of stator lower end cover spring 4 times ends is provided with fitting nut 9, it is connected with joint nut 8 between stator upper end cover spring 3 and stator shell 7, it is connected with joint nut 8 between stator lower end cover spring 4 and stator shell 7, the upper end of stator lower end cover spring 4 is provided with stator core support 10, the upper end of stator core support 10 is provided with stator core 5, stator core 5 is provided with stator winding 6, the top of stator core 5 is provided with rotor permanent magnet 2, rotor permanent magnet 2 is fixedly connected with mover center post 1, described stator core 5, stator winding 6 and rotor permanent magnet 2 are respectively four groups.
Connected by tackiness agent between described permanent magnet 2 and mover center post 1.
Described stator winding 6 is made up of symmetrical two groups of windings, and symmetrical winding is interconnected to constitute a phase.
In stator module, the spring of upper and lower end cap is made up of three identical springs so that mover center post 1 can only motion in the scope that spring allows.
Performer, primarily of four sizes permanent-magnet linear oscillating performer composition completely identical with structure, is accurate Halbach permanent array in mover assembly, and its structure is (direction of arrow represents permanent magnet magnetizing direction) as shown in Figure 5. They are distributed on X/Y plane spaced 90 degree. Wherein two performer are distributed in X-axis, the displacement of controlled mover assembly processed in X-axis, and two other performer is distributed in Y-axis, the displacement of controlled mover assembly processed in Y-axis. From magnetic circuit, mutual decoupling zero between them.
The stator winding 6 piled passes to symmetrical two-phase sinusoidal voltage (differing 90 degree of electrical angles) as follows respectively, then can produce the synchronous rotary electromagnetic force that contactless, direction is radial, amplitude and phase-adjustable on moving parts.
Um in formula is phase voltage amplitude, and �� is excitation force frequency, taking A phase as reference.
Mover assembly central shaft around performer under the driving of this electromagnetic force makes uniform circular motion, and rotation does not occur mover assembly itself. Mover assembly and one of them welded piece are fixed together, and this workpiece can make uniform circular motion relative to fixing welded piece like this. Due to relative movement fast, the contact surface of two welded pieces creates heat of friction, make piece surface produce viscous deformation and connect fusion. Then, under the effect of upsetting force, spring makes motion workpiece return starting position and centering, stops vibration friction. Tracking frictional vibration performer controls the vibrational frequency of workpiece, vibrates amplitude and weld interval, it is resolved that welding joint quality. It is added on stator coil voltage characteristic (frequency, size etc.) by control, the size of adjustable amplitude, also can realize becoming track (circular, oval) and run, meet different welding needs.
