[0002] A motor core, also known as a magnetic core, is made of laminated silicon steel sheets or other magnetic materials. It increases the magnetic flux of the inductor coil and maximizes electromagnetic power conversion. A motor core is generally divided into two parts: the stator core and the rotor core. The stator core is located in the stator portion of the motor and is the stationary part; the rotor core is located in the rotor portion of the motor and is the rotating part. Of the motor cores, the stator core must ensure stability after installation and therefore must have good anti-loosening properties.

[0019] When installing the motor core, the core body 2 is set in the motor housing 1, and the tensioning and fixing structure 5 is connected to the through hole 4 on the inner tube 3, thereby tensioning and fixing the core body 2. Then the tightening structure 6 at the end of the inner tube 3 is operated so that the tightening structure 6 abuts against the motor housing 1, thereby fixing the other end of the core body 2. Under the joint action of the tightening structure 6 and the tensioning and fixing structure 5, the core is firmly installed in the motor housing 1. After installing other structures of the motor, it is put into use. During use, the core body 2 has good stability and will not loosen, thereby ensuring stability in use.

[0020] According to the above embodiment, the tensioning and fixing structure 5 includes a fixing plate 501, a positioning rod 502, a threaded hole 503, a deformation hole 504, a connecting rod 505, an adjusting bolt 506 and a hexagonal slot 507. The fixing plate 501 is fixedly connected to the positioning rod 502, the threaded hole 503 and the deformation hole 504 are opened on the positioning rod 502, the connecting rod 505 is fixedly connected to the adjusting bolt 506, and the adjusting bolt 506 is connected to the threaded hole 503 on the positioning rod 502, and the hexagonal slot 507 is opened at the end of the connecting rod 505. The tightening structure 6 includes The fixing block 601, the tightening plate 602, the connecting block 603, the tightening spring 604, the cylinder 605, the slot 606, the tightening bolt 607, the insertion rod 608 and the annular protrusion 609, the fixing block 601 is fixed to the inner cylinder 3, the tightening plate 602 is fixedly connected to the connecting block 603, the ends of the tightening spring 604 are respectively connected to the fixing block 601 and the connecting block 603, the slot 606 is provided on the cylinder 605, and the cylinder 605 is fixed to the tightening plate 602, the slot 606 is provided with an annular groove, the tightening bolt 607 and the insertion rod 608 are fixed. The inner tube 3 is fixedly connected, and the tightening bolt 607 is threadedly connected to the inner tube 3. The annular protrusion 609 is set at the end of the insertion rod 608, and the end of the insertion rod 608 is inserted into the slot 606. The core body 2 is connected to the tensioning and fixing structure 5 by the provided tensioning and fixing structure 5. The positioning rod 502 can be opened by adjusting the bolt 506 so that the positioning rod 502 is close to the inner wall of the through hole 4, thereby improving the stability of the core body 2 after installation. A tightening structure 6 is provided on the inner tube 3, and the tightening bolt 607 in the tightening structure 6 cooperates with the tightening plate 602 to It can play a role of tightening and fixing the corresponding ends of the inner cylinder 3, and when used in conjunction with the tensioning and fixing structure 5, it can increase the stability of the entire iron core after installation, so that the motor iron core has a good anti-loosening effect. A tightening spring 604 is set between the tightening plate 602 and the inner cylinder 3, which can play a pre-fixing effect. A cylinder 605 is set on the tightening plate 602, and the cylinder 605 is adapted to the insertion rod 608 through the slot 606. When installing the iron core, the tightening plate 602 can be moved to connect to the insertion rod 608, thereby forming a gap, which will not affect the rapid installation of the iron core.

[0021] Before installing the core body 2, operate the clamping plate 602 so that the clamping plate 602 moves toward the inner cylinder 3 and compresses the clamping spring 604 on the connecting block 603 and the fixing block 601 until the insertion rod 608 is inserted into the slot 606 on the cylinder 605. At this time, the annular protrusion 609 is connected with the annular groove, so that the cylinder 605 and the insertion rod 608 are firmly connected.

Under the action of the clamping spring 604, the clamping plate 602 is pressed against the inner wall of the motor housing 1, thereby pre-fixing the core body 2. Then, the end of the hexagonal handle with magnetic attraction is set into the hexagonal groove 507, and the connecting rod 505 is set into the through hole 4. The connecting rod 505 is rotated with a hexagonal wrench so that the adjusting bolt When the screw thread 506 is screwed into the threaded hole 503, as the adjusting bolt 506 rotates and moves, the positioning rod 502 expands outward through the deformation hole 504, thereby pressing against the inner wall of the through hole 4, and then the tensioning fixing structure 5 is used to complete the fixing work of one end of the inner cylinder 3. Then, the corresponding hexagonal wrench is used to turn the tightening bolt 607 at the groove 7. The tightening bolt 607 rotates and moves on the inner cylinder 3, and the insertion rod 608 moves along with it. When the insertion rod 608 is inserted into the slot 606 on the cylinder 605, the insertion rod 608 has a tightening effect on the cylinder 605, and the tightening force is transmitted to the tightening plate 602, so that the tightening plate 602 is in close contact with the inner wall of the motor housing 1, thereby fixing the other end of the inner cylinder 3, and then completing the fixing work of the entire inner cylinder 3. When the iron core body 2 is installed and used, under the action of the tensioning fixing structure 5 and the tightening structure 6, the inner cylinder 3 has good stability, so that the entire motor iron core has a good anti-loosening effect, thereby ensuring stability in use.
