Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is superfinishing machinery motion control device structure partial schematic diagram of the present invention, a kind of superfinishing machinery motion control device, comprise the linear axis 1 of non-magnetic material, on linear axis 1, be socketed with axle sleeve 2, in described linear axis 1, be provided with the first magnet 3 of some intervals stationary arrangement, in axle sleeve 2, be provided with the second magnet, the pole orientation of the first magnet 3 and the second magnet all with the axially parallel of linear axis 1; The magnetic field producing by the first magnet 3 and the second magnet, axle sleeve 2 does the mechanical movement of axial reciprocating along linear axis 1; Axle sleeve 2 is provided with the entrance 5 that hyperbar enters, and axle sleeve 2 is provided with pore with the internal ring wall that linear axis 1 contacts.
The first magnet 3 is annular permanent magnet, and the second magnet is solenoid; Or the first magnet 3 is solenoid, and the second magnet is annular permanent magnet; Permanent magnet is permanent magnet.
The internal ring wall of axle sleeve 2 is corresponding with the external surface shape of linear axis to coincide, the girth of axle sleeve internal ring wall is a bit larger tham the outer surface girth of linear axis, axle sleeve is socketed on linear axis, as the some permanent magnets of even placement along its axial linear in linear axis, between two adjacent permanent magnet with isolating as non-magnetic objects such as rubber, have like this N of several interruptions in linear axis inside, S magnetic pole is along the direction linear array of linear axis.
The winding direction of the solenoid in axle sleeve is consistent with the direction of internal ring wall girth, when use, solenoid is connected with power supply, hyperbar is injected in axle sleeve from entrance simultaneously, the pore of gases at high pressure from axle sleeve internal ring wall ventilated to linear axis, makes axle sleeve float with respect to linear axis; Owing to can producing magnetic field after solenoid energising, the magnetic field interaction with permanent magnet produces, makes axle sleeve do the mechanical movement of axial reciprocating along linear axis simultaneously.
If the first magnet and the second magnet all adopt permanent magnet, in the time that device shuts down, magnetic fields between two permanent magnets is but operating always, and equipment is likely caused to unexpected failure, so preferred scheme is, one of them is permanent magnet for the first magnet and the second magnet, another is non-permanent magnet, and non-permanent magnet is preferably solenoid, and permanent magnet is preferably annular permanent magnet, only have in the time that control device need to turn round, just by solenoid and external power supply UNICOM.
Further improve, linear axis 1 is provided with grating ruler, and axle sleeve is provided with grating reading head 4, and described grating reading head 4 is connected with for connecting power supply and transmitting the circuit of data.In some high-precision technological processes, the position that axle sleeve is moved needs accurately location, and often adopts grating scale as measuring transducer in Precision Machining and accurate displacement measurement at present, accesses thereafter intelligent numerical control system and carries out displacement measurement.Grating reading location coordinates frictional force in the present invention to be tending towards mechanical movement control device infinitely small, that vibration goes to zero, its positioning function can realize zero error substantially, especially in the application of the industries such as printing, thin-film material processing, weaving, packaging, mine, Aero-Space, medical treatment, electron stream waterline, military project, this superfinishing motion control is measured integrated device and is even more important.
