Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
A kind of linear electric motors comprise steel ball 1, screw mandrel 2, nut 3, mounting panel 4, fore bearing 5, front pad 6, casing 7, middle pole plate 8, magnet ring 9, injection molding body 10, back pad 11, rear bearing 12, skeleton 13 and back shroud 14.
As Fig. 1 is structural representation of the present invention, a kind of linear electric motors, comprise casing 7, pole plate 8, skeleton 13 and mounting panel 4 in being provided with in the casing 7, described casing 7 and back shroud 14 are spot-welded together, described skeleton 13 axis are provided with screw mandrel 2, and an end of described screw mandrel 2 is provided with steel ball 1, and the other end is provided with rear bearing 12.Screw mandrel 2 is movable in rear bearing 12.This micromachine simple in structure is skillfully constructed, and simple principle has been applied in the actual production cleverly, makes its operating efficiency improve greatly, improved the quality of production.
Be provided with back pad 11 between described screw mandrel 2 and the rear bearing 12.Described back pad 11 is to make with paper, rubber tissue or copper sheet, is placed between 5 liang of planes of screw mandrel 2 and fore bearing to strengthen its sealing property, prevents that escape of liquid is arranged on the potted component between the static seal face.
Be provided with magnet ring 9 and injection molding body 10 between described screw mandrel 2 and the skeleton 13.Magnet ring 9 is anti-interference elements commonly used in the electronic circuit, for high-frequency noise the good restraining effect is arranged, and generally uses Ferrite Material (Mn-Zn) to make.Injection molding body 10 can play the effect of damping, guarantees the normal operation of motor.
Described screw mandrel 2 and injection molding body 10 are flat formula or triangle or parallelogram, and described screw mandrel 2 is flexible connection in injection molding body 10.As Fig. 2 is the schematic diagram of screw mandrel 2, and screw mandrel 2 is (see figure 3)s of flat formula, and the screw mandrel 2 with this flat formula drives the screw rods rotation then, during the screw rod rotation under the effect of nut 3 rectilinear motion up and down; As Fig. 4 is the schematic diagram of injection molding body 10, and injection molding body 10 is (see figure 5)s of flat formula, and the screw mandrel 2 of flat formula is movable in the injection molding body 10 of flat formula, thereby reaches straight-line purpose.Screw mandrel 2 and injection molding body 10 can be shapes such as flat formula or triangle or parallelogram.
One side of described mounting panel 4 is a skeleton 13, and opposite side is a nut 3.By the fixing central axis direction of screw mandrel 2 and nut 3 of mounting panel 4, guarantee screw mandrel 2 in along with rotor rotation, axial gyration is changed into the reciprocating motion of straight line.
