[0003] Traditional motor stator lamination has some drawbacks. During motor operation, heat is generated, and the stator lamination positioning mechanism is prone to accuracy deviation due to temperature changes, making it impossible to effectively position the stator laminations, which in turn affects the overall operational stability of the motor. Summary of the Invention

[0004] The main objective of this invention is to provide a stator lamination positioning structure for motors, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

A positioning auxiliary mechanism is provided on the inner side of the housing body. The positioning auxiliary mechanism includes a fixed seat fixedly connected to the inner wall of the housing body. A guide ring is fixedly connected to one end of the fixed seat, and a contact ring is fixedly connected to one end of the guide ring. A support plate is fixedly connected to the inner wall of the fixed seat. A mounting plate is fixedly connected to the lower end of the support plate. A control seat is fixedly connected to one end of the mounting plate. A rotating groove is formed inside the control seat, and a movable groove is formed at one end of the control seat. A limit block is movably connected to the inner side of the rotating groove, and a connecting rod is movably connected to the inner side of the movable groove.

[0009] Preferably, there are multiple sets of support plates, the rotating groove and the movable groove are interconnected, the front end of the limiting block is fixedly connected to the rear end of the docking rod, and the diameter of the limiting block is larger than the diameter of the docking rod.

[0010] Preferably, the stator lamination core is installed inside the housing body, a connecting seat is installed inside the stator lamination core, the drive shaft is installed inside the connecting seat, an auxiliary ring is installed on the inner side of the housing body near the stator lamination core, and one end of the contact ring is in contact with one end of the stator lamination core.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By activating the main body of the housing, the drive shaft rotates, causing the connecting rod and the limiting block to rotate in the movable groove and the rotating groove, respectively. At the same time, the contact ring limits the stator lamination core to a designated position. This allows the drive shaft to effectively position the stator lamination core under stable operation, thereby preventing the stator lamination core from shifting within the main body of the housing and improving the stability of the main body's operation.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] As shown in Figures 1-4, a motor stator lamination positioning structure includes a housing body 1, a stator lamination core 2, and a drive shaft 4. A positioning auxiliary mechanism 6 is provided on the inner side of the housing body 1. The positioning auxiliary mechanism 6 includes a fixed seat 61 fixedly connected to the inner wall of the housing body 1. A guide ring 62 is fixedly connected to one end of the fixed seat 61, and a contact ring 63 is fixedly connected to one end of the guide ring 62. A support plate 64 is fixedly connected to the inner wall of the fixed seat 61. An mounting plate 65 is fixedly connected to the lower end of the support plate 64. A control seat 66 is fixedly connected to one end of the mounting plate 65. A rotating groove 67 is opened inside the control seat 66, and a movable groove 68 is opened at one end of the control seat 66. A limit block 69 is movably connected to the inner side of the rotating groove 67, and a docking rod 610 is movably connected to the inner side of the movable groove 68.

[0021] In this embodiment, one end of the docking rod 610 is fixedly connected to a corresponding seat 611, and one end of the corresponding seat 611 is fixedly connected to a contact piece 612. The centerlines of the fixed seat 61, guide ring 62, contact ring 63, mounting plate 65, control seat 66, limiting block 69, docking rod 610, corresponding seat 611, and contact piece 612 are located on the same straight line. There are multiple sets of support plates 64. The rotating groove 67 and the movable groove 68 are interconnected. The front end of the limiting block 69 is fixedly connected to the rear end of the docking rod 610, and the diameter of the limiting block 69 is larger than the diameter of the docking rod 610.

[0022] Specifically, the drive shaft 4 drives the contact piece 612 to rotate, which in turn causes the contact piece 612 to drive the docking rod 610 to rotate in the movable groove 68 via the corresponding seat 611, and causes the limiting block 69 to rotate in the rotating groove 67. This allows the drive shaft 4 to rotate smoothly, and the contact ring 63 to contact the stator lamination core 2, thus limiting the stator lamination core 2 to a designated position within the housing body 1. This prevents the stator lamination core 2 from shifting. By starting the housing body 1, the drive shaft 4 rotates, causing the docking rod 610 and the limiting block 69 to rotate in the movable groove 68 and rotating groove 67, respectively. At the same time, the contact ring 63 limits the stator lamination core 2 to a designated position, which facilitates the effective positioning of the stator lamination core 2 by the drive shaft 4 under stable operation, thereby preventing the stator lamination core 2 from shifting within the housing body 1 and improving the operational stability of the housing body 1.

[0023] In this embodiment, the stator lamination core 2 is installed inside the housing body 1. A connecting seat 3 is installed inside the stator lamination core 2. The drive shaft 4 is installed inside the connecting seat 3. An auxiliary ring 5 is installed on the inner side of the housing body 1 near the stator lamination core 2. One end of the contact ring 63 is in contact with one end of the stator lamination core 2. One end of the auxiliary ring 5 is in contact with the other end of the stator lamination core 2. One end of the contact piece 612 is in contact with one end of the drive shaft 4. The drive shaft 4 passes through the interior of the housing body 1 and is movably connected to the housing body 1.

[0024] Specifically, the main body 1 of the housing is installed at a designated position, and then the drive shaft 4 is connected to a designated transmission device. The main body 1 of the housing is started, which causes the drive shaft 4 to rotate and transmit the rotational force to the external device.

[0025] Working principle:

[0026] In use, first install the main body 1 of the housing in the designated position, then connect the drive shaft 4 to the designated transmission equipment, and start the main body 1. This causes the drive shaft 4 to rotate and transmit the rotational force to the external equipment. At the same time, the drive shaft 4 drives the contact piece 612 to rotate, which in turn causes the contact piece 612 to drive the docking rod 610 to rotate in the movable groove 68 via the corresponding seat 611, and causes the limiting block 69 to rotate in the rotating groove 67. This allows the drive shaft 4 to rotate smoothly, and the contact ring 63 to contact the stator lamination core 2, thus causing the contact ring 63 to engage the stator lamination core 2. By confining the stator lamination core 2 to a designated position within the main body 1, displacement of the stator lamination core 2 is prevented. By activating the main body 1, the drive shaft 4 rotates, causing the connecting rod 610 and the limiting block 69 to rotate within the movable groove 68 and the rotating groove 67, respectively. Simultaneously, the contact ring 63 confines the stator lamination core 2 to the designated position. This facilitates effective positioning of the stator lamination core 2 by the drive shaft 4 under stable operation, thereby preventing displacement of the stator lamination core 2 within the main body 1 and improving the operational stability of the main body 1.
