Embodiment 1

[0020] Such as figure 1 , figure 2 , image 3 , Image 6 As shown, the disc motor iron core fixing structure of the present invention includes a stator iron core 1 and an end cover 2 fixedly installed on the end surface of the stator iron core. The end surface of the stator iron core 1 is provided with a number of radially arranged dovetail grooves. 3. The number of dovetail grooves 3 is set according to the specific use requirements, at least two. In order to ensure the reliability of the connection, it can be set to multiple. The dovetail groove 3 is provided with a metal connection block 4 that can cooperate with the dovetail groove. The metal connection block 4 is set as a dovetail structure 7 that can be matched with the dovetail groove 3. The metal connecting block 4 is provided with a threaded hole 5 for connecting with the fastener on the end cover. After the metal connecting block 4 is inserted into the dovetail groove 3 The fastener 6 is connected with the thread...

Abstract

The invention discloses a fixing structure of a motor iron core and specifically relates to an iron core fixing structure of a disc type motor. The iron core fixing structure comprises a stator iron core and an end cover fixedly installed on the end face of the stator iron core, a plurality of radially distributed dovetail grooves are opened on the end face of the stator iron core, metal connection blocks which can be matched with the dovetail grooves are arranged in the dovetail grooves, and the end cover is fixedly connected with the dovetail grooves of the stator iron core through the metal connection blocks. By means of the structure, complicated welding procedures in traditional installations are removed, requirements for assembling processes are reduced, the operation is simple and convenient, the implementation is easy, production costs are effectively reduced, the fixing structure is suitable for mass production, simultaneously, the leveling of a bottom surface of a stator can be effectively achieved, and performances of the motor are greatly improved.

Description

[0001] technical field [0002] The invention relates to a fixing structure of a motor iron core, in particular to a fixing structure of a disc-type motor iron core. Background technique [0003] The stator core of the disc motor is made of silicon steel strips, and it is difficult to directly open the installation hole on the axial end face, so there are great difficulties in fixing the motor core and the motor end cover. In order to overcome this problem, a The title of the article is a Chinese patent on a disc-type motor stator core (publication number: CN201238217), which specifically discloses a method of welding the mounting foot at the bottom of the iron core and connecting it with the motor end cover through screws, but this method The requirements for the welding process are relatively high. During the welding process, due to the local heating of the iron core, it is easy to cause the bottom surface of the stator iron core to be uneven, thereby affecting the per...
