Abstract

The utility model relates to a connecting device of a motor stator iron core, which comprises two stator iron cores which can be combined into a complete stator and a connecting fastener, wherein connecting parts are arranged on two ends of each stator iron core, the connecting fastener is an 'n'-shaped iron core clamp, the opening width of the iron core clamp is slightly smaller than the total width of the connecting parts of the two stator iron cores, and the iron core clamp is fastened and clamped on the connecting parts of the two stator iron cores. The connecting device has high fastening performance and simple assembly structure, assembly can be finished through using simple frocks, and the production operating performance is strong. Compared with connection in a welding mode which is normally adopted, the connecting device is characterized in that the device investment is small, the production cost is low, and the labor intensity of operators is low.

Description

A kind of jockey of motor stator core

Technical field

The utility model relates to the motor stator core technology, and particularly a kind of jockey that is used for the supporting motor stator core of air conditioner belongs to the renovation technique that has motor now.

Background technology

Being connected of existing air conditioner necessary electromotor stator core normally adopts the mode of welding to realize.Specifically adopt the mode of welding to form weld seam one lobe stator core and another lobe stator core, realize being connected.This connected mode need adopt special-purpose welding equipment, is finished by workman's operation, and the shortcoming of existence is: equipment input and manufacturing cost are higher, and the easy distortion that occurs in various degree in iron core welding back, influences the technical performance of later stage assembling and motor.

The utility model content

The purpose of this utility model is to overcome above-mentioned technical disadvantages and provides a kind of can effectively the reduction to make and processing cost, easy, the fastening reliability height of assembly manipulation, and can not bring the jockey of the motor stator core of secondary deformation to iron core.

The technical scheme that realizes the utility model purpose is: the utility model comprises stator core that two lobes can be combined into complete stator and is connected securing member, every lobe stator core two ends are provided with connecting portion, described connection securing member is " ∏ " font iron core folder, the A/F of folder unshakable in one's determination is slightly less than the overall width of two lobe stator core connecting portions, the connecting portion that is clamped in two lobe stator cores admittedly that clamps unshakable in one's determination.

In order to improve the connection tautness between the two lobe iron cores, openend both sides at the iron core folder are respectively equipped with the tooth button that is used to fasten iron core, be provided with catching groove on the position of corresponding teeth button on the stator core connecting portion, the tooth clip on the folder unshakable in one's determination is held in the catching groove on the two lobe stator cores.

Above-mentioned iron core folder is gone up the zigzag that is shaped as of tooth button, and the catching groove on the stator core connecting portion is the zigzag catching groove that fits like a glove with the tooth button.

The tooth button number that above-mentioned iron core folder is gone up every side is 1～3, and corresponding therewith, the catching groove number on every lobe stator core connecting portion also is 1～3.

The beneficial effects of the utility model are: because the utility model directly adopts iron core simple in structure to press from both sides clamping two lobe stator cores to be connected with realization, therefore adopt the mode of welding to compare with prior art, it is simple to the utlity model has assembly structure, the equipment less investment, production cost is low, the production efficiency height, the characteristics that operative employee's labour intensity is low; The tooth button of iron core folder is with after the catching groove on the iron core connecting portion cooperates, and the opening of two tooth buttons can become greatly slightly, and iron core presss from both sides and utilizes this to be out of shape the elastic force of generation, can prevent effectively that it from getting loose from iron core, fastening reliability height.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described further.

As shown in Figure 1, 2, 3, being connected of existing air conditioner necessary electromotor stator core normally adopts the mode of welding to realize.Specifically adopt the mode of welding to form weld seam 5 a lobe stator core 3 and another lobe stator core 3, realize being connected.

As Fig. 4,5, shown in 6, the utility model comprises the two lobe stator cores 3 that can be combined into complete stator and is connected securing member, every lobe stator core 3 two ends are provided with connecting portion 6, described connection securing member is " ∏ " font iron core folder 1, the A/F of folder 1 unshakable in one's determination is slightly less than the overall width of two lobe stator core connecting portions 6, openend both sides at iron core folder 1 are respectively equipped with 1 serrated teeth button 2 that is used to fasten iron core, be provided with 1 zigzag catching groove 4 that fits like a glove with tooth button 2 on the position of corresponding teeth button 2 on the connecting portion 6 of stator core 3, catching groove 4 is to utilize the mould stamping-out to finish processing; Tooth button 2 on the folder 1 unshakable in one's determination is clamped in the catching groove 4 on the two lobe stator cores 3.

The tooth button 2 on the above-mentioned iron core folder 1 and the quantity of the catching groove 4 on the stator core 3 can also be 2 or 3; Shape can also be triangle, trapezoidal (not shown in the accompanying drawing).

Fig. 7, Fig. 8 are the structural representation of two kinds of multi-form iron core folders of the utility model, and two the tooth buttons 2 on the iron core folder 1 shown in Figure 7 adopt integral molded plastic to be shaped; Two tooth buttons 2 on the iron core folder 1 shown in Figure 8 use the sheet metal drawing.
