Embodiment
Get back to Fig. 1, illustrate, and come mark with numeral 10 according to electric tool of the present invention.Shown electric tool 10 is electric drills; Yet the electric tool of other form is screwdriver for example, sander, and turning tool, shear, saws etc. all can utilize a motor that uses in the present invention, and electric tool 10 comprises the housing 12 of an encirclement motor 14.An actuated components 16 is connected with motor 14 by a power source 18.Power source 18 can be that power line (alternating current) or electric tool can have a battery (direct current) as shown in the figure.This motor 14 is connected with output block 20, and this output block may comprise that a driving member 22 and a chuck 24 block an instrument (not drawing) on electric drill.
Motor 14 comprises 30, one welded rings 34 of stator component and magnet 36 and 38 that are arranged in housing 32.Armature 40 comprises that 42, one on an axle has the rotor 44 of lamination 46 and winding 48, and one with the axle 42 commutators that are connected 50.This motor also comprises end plate 52 and 54.End plate 52 comprises a bearing 56, comes an end of the axle 58 that balance is connected with pinion 60 as an electric tool output part.Brush 62 and 64 and commutator 50 interrelate, bearing 70 also links to each other with end cap and fetches the rotation of trunnion shaft 42.
Get back to Fig. 2, on welded ring 34, illustrate magnet 36 and 38.Magnet 36 and 38 is made by a kind of magnetic material of casting.Especially, this cast material is a kind of injection cast material.This welded ring 34 is arranged in a mould and this magnetic material is that die casting is to this welded ring.In addition, can be with this housing 32 as welded ring.Like this, the discussion about welded ring 34 just is equal to the metal shell 32 of having used motor 14.
Welded ring 34 comprises that anchor 80 is stuck in magnet 36 and 38 on the welded ring 34.Anchor 80 has two kinds of forms.First kind, anchor 82 is holes that form on welded ring 34.There are the first 84 and the second counterbore part 86 in this hole.This counterbore part 86 extends on the outer surface 88 of ring 34.Like this, shown in the cross-sectional view of Fig. 3, when the magnetic material of will casting was put in the hole, this cast material had a neck 92 and head 94.This head 94 and neck 92 have constituted the rivet appearance profile, and big like this head 94 plays magnet 36 and 38 is stuck in the effect that encircles on 34.This ring 34 can be made up of a plurality of holes is held on the welded ring 34 magnetic catch.
Other anchor 96 also can use on this ring.Anchor 96 highlights from encircling 34 inner surface.Usually, this anchor 96 is to make by the hole 100 that methods such as punching press form near outstanding anchor 96 on ring 34.Like this, when the casting magnetic material formed around outstanding anchor 96, it can flow into equally under this device 96 and with hole 100 and be full of.This provides a kind of method that securely magnet is fixed on the welded ring 34.
The welded ring 34 shown in Figure 2 magnet that in Fig. 4, do not draw.As shown in the figure, Tu Chu anchor 96 has rectangular profile and its end 102 and 104 integrally formed with ring 34.This anchor is provided with crooked joint 106 and 108 between support 110,112 and web 114.Strengthening gusset piece 116 is positioned on crooked joint 106 and 108.This reinforcement gusset piece 116 strengthens the intensity of anchor and can keep its shape in casting cycle.This reinforcement gusset piece 116 can be dimple or the groove on crooked joint.Equally, Fig. 4 shows the anchor 82 of opening.In addition, can remove the anchor 82 of this opening and only use radially outstanding anchor 96 that magnetic catch is held in the housing.
Welded ring 34 is normally made by rectangular metal plate.The anchor 96 that the rectangular metal plate punching press is portalled or had the projection of strengthening gusset piece 116, perhaps these two kinds is that fixed system all needs.Then the conglobate ring of this metal plate coils also can there be a banjo fixing butt jointing 99 (as shown in the figure), end of engagement 101 (as shown in Figure 6) or the like, and form a ring.This ring is placed in the mould again magnetic material is ejected on this ring.This injection molding material flows through this hole and flows to as shown in Figure 3 around the anchor 96 of projection.Then, should encircle and remove, and prepare to be put in the electric machine casing from mould.Equally, this electric machine casing itself can be used as welded ring.In this case, this welded ring is not existing and magnet can be cast straight on the housing, forms together with this housing as mentioned above.
Arrive Fig. 5-9 again, illustrate other embodiment of the present invention.Among Fig. 5, the foregoing optional opening anchor 82 of welded ring 34 ' comprise.Here, the anchor 120 of projection have the profile of a rectangle and an end be fixed to this ring 34 ' on.This reinforcement gusset piece 116 forms on crooked joint.In addition, hole 122 is near the anchor 120 of projection.
Specifically introduce Fig. 6, say another ring 34 ".Herein, ring 34 " comprises foregoing optional opening anchor 82.Here, the anchor 130 of projection has a L shaped profile.The L of this projection is fixed to this ring 34 " an end on.To strengthen gusset piece 116 be at ring 34 " near formation.Hole 132 is near the L shaped anchor 130 of projection, has L shaped equally.
Fig. 7 shows another embodiment.Herein, the anchor 140 that encircles 34 and projection comprises foregoing optional opening anchor 82.The anchor 140 of projection has the profile of a rectangle and directly from encircling inwardly angled stretching of 34 .Strengthening gusset piece 116 is near formation ring 34 .In addition, hole 142 is near projection anchor 140.
Fig. 8 shows an alternative embodiment of the invention, encircles 34 ' and comprises foregoing optional opening anchor 82.The anchor 160 of projection has the profile of a T shape.Hole 162 has corresponding T shape equally near the T shape anchor 130 of projection.Strengthen gusset piece 116 and be near ring 34 ' formation.Like this,, on this T shape projection 160, cover magnetic material, and T shape hole 162 has held magnetic material and also magnet has been fixed on ring 34 ' when magnetic material being cast to ring when going up.
Get back to Fig. 9, say another embodiment of welded ring 34 '.Encircle 34 ' herein, and comprise foregoing optional opening anchor 82.The anchor 150 of projection has the profile of a truncated cone shape.This truncated cone 150 comprises axial hole 152.This axial hole can make the magnetic material of casting flow in the cone 150 that the outer surface by welded ring 34 " " forms.
Most preferred embodiment of the present invention more than has been described, but the present invention is not limited to this, self-evident, also can do more variation without departing from the spirit and scope of the present invention.
