Abstract

The utility model discloses a stator keeps ware and motor stator. This stator keep the ware include with the winding internal diameter matched with ring body of the stator of waiting to mould plastics. Since the ring body when moulding plastics with winding inner wall contact, the in -process of consequently moulding plastics not only can prevent the winding mould plastics aversions, warp unusually, the stator of still can avoiding moulding plastics reveals the problem of copper to can produce stator assembly a school dropout, reach staff reduction and efficiency improvement's purpose.

Description

Stator retainer and motor stator

Technical field

The utility model is related to stator manufacture field, in particular to a kind of stator retainer and motor stator.

Background technology

The production technology that iron-clad of the prior art turns plastic packaged motor stator is cumbersome, including rule stator, stator dipping, fixed Son cooling, stator injection etc., need numerous operating personnel, and time-consuming for stator turnover, it is impossible to make stator realize a stream production. Additionally, in this process, need stator dipping, its objective is to increase the stress levels of stator winding and the hardness of winding, prevent In the sub- injection moulding process of fastening, winding is abnormal by BMC plastic packaging material detrusions position, deformation etc., and stator injection is then carried out again.

But, when using stator dipping technique, stator is during dipping lacquer, and the diameter meeting resilience of stator winding is (i.e. fixed Sub- internal diameter diminishes), so as to cause injection moulding process in stator winding with injection core contact, so as to cause be molded after winding outside Dew.

Utility model content

A kind of stator retainer and motor stator are provided in the utility model embodiment, to solve prior art in cannot make Stator realizes that the problem of copper is revealed in a stream production, injection moulded stator.

For achieving the above object, the utility model embodiment provides a kind of stator retainer, including with treat injection moulded stator The ring body that winding inner diameter is engaged.

Preferably, being protrusively provided reinforcement on the inside of ring body.

Preferably, reinforcement is in the form of a column.

Preferably, one end of reinforcement protrudes from the outside of ring body.

Preferably, one end of reinforcement has guide part.

Preferably, reinforcement protrudes from afterbody and the transition part that the part of ring body includes setting gradually, the thickness of transition part Degree towards the direction of afterbody along tapering into.

Preferably, the ring body includes inner ring body and the outer ring body being arranged on the outside of the inner ring body, the inner ring body It is connected by base ring with the side of the outer ring body, the inner ring body, the base ring and the outer ring body form the channel-shaped knot of U-shaped Structure.

The utility model additionally provides a kind of motor stator, including stator department and above-mentioned stator retainer, and stator keeps Device is placed at the winding inwall of stator department, and stator retainer is combined into one by way of injection with stator department.

Because ring body is contacted in injection with winding inwall, therefore can not only prevent winding injection from moving in injection moulding process Position, deformation are abnormal, can also avoid injection moulded stator from revealing the problem of copper, in a stream production, reach and subtract such that it is able to by stator general assembly The purpose of member's synergy.

Specific embodiment

Below in conjunction with the accompanying drawings the utility model is described in further detail with specific embodiment, but not as to this practicality New restriction.

Fig. 1 to Fig. 7 is refer to, the utility model provides a kind of stator retainer, and it includes ring body 1.The external diameter of ring body 1 Match with the winding inner diameter for being molded stator is waited, to contact with winding inwall when in use.Preferably, in the utility model Stator retainer flexibility so can not only increased using nylon66 fiber material and 30% glass, and with higher Rigidity, heat resistance and wearability.

Before injection, the stator retainer in the utility model is fitted in stator coil, so in injection moulding process, ring Body 1 not only can be molded displacement, deformation exception with winding, can also avoid because winding displacement is so that the core rod of winding and injection mold Contact, so as to cause injection moulded stator to reveal the problem of copper.

Further, because ring body 1 with winding inwall contacting, therefore in injection moulding process, realize stator and exempt to soak work Skill, in a stream production, the purpose of personnel reduction and enlargement is reached such that it is able to by stator general assembly.

In a preferred embodiment, the inner side of ring body 1 has been protrusively provided reinforcement 2, can be increased using reinforcement 2 The intensity of ring body 1, for example, is equably provided with 12 reinforcements 2 in the circumference of ring body 1.So, can using reinforcement 2 come The impulsive force of BMC in injection moulding process is overcome, so as to further improve the effect for preventing deforming.Preferably, reinforcement 2 is in the form of a column. Further, since the whole stator retainer after injection has expected bag note by BMC, accordingly, it would be desirable to by using these reinforcements 2 and mould Core is contacted, so as to strengthen injection after BMC plastic packaging materials and retainer adhesion.

One end that reinforcement 2 is preferably made in the utility model protrudes from the outside of ring body 1, i.e. the height of reinforcement 2 is big In the thickness of ring body 1.It is highly preferred that one end for protruding from ring body 1 of reinforcement 2 has the guiding for being molded and assembling Portion, the size of the concrete shape of guide part can highly be designed according to product, to solve assembling process in abnormal conditions and stator Operability in production process assembling, improves operating efficiency.

Preferably, reinforcement 2 protrudes from the part of ring body 1 including the afterbody 3 and transition part 4 for setting gradually, transition part 4 Thickness towards the direction of afterbody 3 along tapering into.Because transition part 4 has certain gradient, therefore can play certain Guide effect, consequently facilitating employee's assembling and the flowing of injection moulding process BMC material.

Fig. 8-10 illustrates an another embodiment of the present invention, wherein, ring body 1 includes inner ring body 7 and is arranged on the inner ring The outer ring body 8 in the outside of body 7, the inner ring body 7 is connected with the side of the outer ring body 8 by base ring 9, the inner ring body 7, described Base ring 9 and the outer ring body 8 form the groove-like structure of U-shaped.

The utility model additionally provides a kind of motor stator, including stator department 5 and above-mentioned stator retainer 6, and stator is protected Holder 6 is placed at the winding inwall of stator department 5, and stator retainer 6 is combined into one by way of injection with stator department 5.

Certainly, it is more than preferred embodiment of the present utility model.It should be pointed out that for the ordinary skill of the art For personnel, on the premise of without departing from the utility model general principle, some improvements and modifications can also be made, these improvement Protection domain of the present utility model is also considered as with retouching.
