It is above -mentioned motor stator fixing structure is simple structure not only, easily realizes, and motor stator is fixed reliable stable, and motor operating noise is little, has guaranteed the whole operating efficiency and the performance of motor.
Description
Technical field
The utility model belongs to motor manufacturing technology, particularly relates to a kind of motor stator fixed structure.
Background technology
At present, major part electric motor end cap fixed connection structure in the following way: be provided with in the periphery of casing several connect projection, each connection projection offers connecting hole, also offering connecting hole corresponding on electric motor end cap, with electric motor end cap, electric motor end cap being fixedly connected with casing through connecting projection by connecting bolt.
But, for the motor of some particular/special requirements, its casing periphery of customer requirement can not arrange connection projection, will redesign the fixed form of end cap like this, refer to shown in Fig. 1, Fig. 1 is the schematic diagram of a kind of motor stator fixed structure in prior art, be provided with in the link inside of the case 11 of motor case 10 in this structure and connect boss 12, described connection boss 12 offers screwed hole 13, to axially offering connecting hole along it by screwed hole 13 on motor stator 14, corresponding connecting hole offers through hole on electric motor end cap 15, connecting bolt 16 is successively through through hole, connecting hole lock onto in described screwed hole 13, and described connecting bolt 16 is provided with holddown spring 17 between electric motor end cap 15 and motor stator 14, by the elastic force of holddown spring 17, motor stator 14 is pressed on connection boss 12.By connecting bolt 16, motor stator 14 and electric motor end cap 15 are connected as one in this structure, thus achieve the fixing of electric motor end cap 15 and motor stator 14.The fixed structure of obvious this form is in the running of motor, because motor stator 14 is just fixed by the elastic force of holddown spring 17, can produce motor stator 14 along connecting bolt 16 play, cause motor noise comparatively large, also can affect efficiency and the performance of motor simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of motor stator fixed structure, and it has the simple and motor stator of structure and fixes reliable and stable feature, to solve the problems referred to above of motor stator fixed structure existence in prior art.
For reaching this object, the utility model by the following technical solutions:
A kind of motor stator fixed structure, it comprises motor case, electric motor end cap, motor stator, head rod, second connecting rod and connector, the case link inside of described motor case is provided with connection boss, described connection boss offers connecting hole, to axially offering stator through hole along it by connecting hole on motor stator, corresponding stator through hole offers end cap through hole on described electric motor end cap, wherein, described head rod is connected to one end of described connector successively through connecting hole and stator through hole, one end of described motor stator is resisted against on described connection boss, the other end is fixed and clamped by described connector, described second connecting rod is connected to the other end of described connector through described end cap through hole.
Especially, described head rod and the second connecting rod are respectively the first connecting screw rod and the second connecting screw rod, described connector is a coupling nut, described first connecting screw rod is connected to one end of described coupling nut successively through connecting hole and stator through hole, one end of described motor stator is resisted against on described connection boss, the other end is by described coupling nut and tightly, electric motor end cap is fixed on described motor case by the other end that described second connecting screw rod lock onto described coupling nut through described end cap through hole.
