Technical field
The utility model relates to the micromachine field of components, is specifically related to a kind of micro motor end cover.
Background technology
Micromachine is widely used in the various fields such as industry automatic control, office automation, small-sized electronic product, toy for children; And the rotor of output shaft axle of micromachine connects owing to need and drives external loading, and rotor of output shaft axle need to pass from the centre bore of motor stator end cap.At present, existing micro motor end cover is generally barrel-like structure, be used for being nested with an end of motor stator in the groove cave of end cap, the stator of motor is played sealing and protective action, in the groove cave of end cap bottom centre, only offer the only centre bore that passes of power supply machine rotor of output shaft axle spindle nose; During machine operation, the rotor high-speed rotation, the friction of its magnetic force induction and bearing can cause that whole the motor feels hot, because existing electric motor end cap has only been offered a through hole that power supply machine rotor of output shaft axle spindle nose passes, radiating effect is bad, causes the motor heat to be assembled in a large number, if untimely dissipating, motor is at high temperature operation for a long time, will seriously reduce motor useful life.Simultaneously, the position of installing motor earth connection is not set on the existing electric motor end cap, when motor carries out ground connection, often earth lead can only be welded direct on the motor housing, not only affect the attractive in appearance of motor housing, motor housing is caused certain damage, and the weldering of earth lead is established and dismantled all and to need by welding equipment, complex operation, operating efficiency is low.
The utility model content
For solving the problems of the technologies described above; we have proposed a kind of micro motor end cover; it can protect the motor output shaft end to avoid the external force direct collision; can well ensure again the efficiently radiates heat of output shaft end; can also make things convenient for simultaneously installing and the dismounting of motor earth connection, improve the operating efficiency of the installing of motor earth connection and dismounting.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of micro motor end cover, the stator case of its inner chamber groove cave and rotor output shaft end is suitable, described end cap bottom centre place offers a cylindrical axis hole that passes for described rotor output shaft spindle nose, and described end cap bottom also offers a plurality of louvres in described axis hole periphery; Described end cap waist radially offers at least one along described motor and leads in the ground hole on described electric machine casing surface; Described end cap inner side end has the groove that can install metal moat sheet, has the grounding connection hole that communicates with described ground hole in the described groove.
Preferably, described a plurality of louvre is for to arrange with the annular array of described axis hole concentric.
Pass through technique scheme, a kind of micro motor end cover of the present utility model, by the louvre of offering near described axis hole side in its end cap bottom, the heat of rotor output shaft end is in time lost, avoid the overheated damage that brings to motor of rotor of output shaft axle end, prolonged the useful life of motor.Simultaneously by in the described ground hole that communicates and described grounding connection hole, installing respectively securing member and the screw of conduction, and make it to be fastenedly connected, it is both fastening with electric machine casing, electric leakage with the electric machine casing surface conducts on the metal moat sheet of installing in the described groove again, by wire metal moat sheet is carried out the ground connection operation that ground connection is namely finished electric machine casing again; When carrying out the earth connection field-strip, only need to remove metal moat sheet and get final product.Its whole ground connection installing and dismantlement work do not need by welding equipment, and be simple to operation, greatly improved the efficient of the installing of motor earth connection and dismantlement work.

Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Below in conjunction with embodiment and embodiment the utility model is described in further detail.
Embodiment:
As shown in Figure 1, a kind of micro motor end cover 1, the stator case of its inner chamber groove cave and rotor output shaft end is suitable, and end cap 1 bottom centre place offers a cylindrical axis hole 2 that supplies described rotor output shaft spindle nose to pass, and end cap 1 bottom also offers a plurality of louvres 3 in axis hole 2 sides; Such as Fig. 2, Fig. 3 and shown in Figure 4, end cap 1 waist radially offers at least one along described motor and leads in the ground hole 4 on described electric machine casing surface; End cap 1 top end face has the groove 6 that can install metal moat sheet 5, has the grounding connection hole 7 that communicates with ground hole 4 in the groove 6; Louvre 3 is the annular array hole with axis hole 2 concentrics.
