Technical Field

[0001] This utility model relates to the field of motor core processing technology, specifically a motor core coaxiality correction fixture. Background Technology

[0002] The motor core is a crucial component in electrical equipment such as motors and transformers. Its primary function is to provide a magnetic flux path, allowing current to generate a magnetic field within the motor, thereby driving its operation. The core is typically made of specific materials (such as silicon steel sheets), and its design and manufacturing directly impact the motor's efficiency, stability, and performance.

[0003] During use, the coaxiality of the motor core may become inaccurate, requiring workers to correct it. During this correction process, the motor core is usually held by hand or placed in a certain position, which may cause the core to shift and affect the normal progress of the correction work.

A column 4 is fixedly connected to the top end of the turntable 3. An arc-shaped receiving plate 5 is fixedly connected to the top end of the column 4. A clamping mechanism 6 is provided at the top end of the turntable 3. A first clamping plate 61 is fixedly connected to the outer wall of the arc-shaped receiving plate 5.

[0018] The first clamping plate 61 has a slide rail 62 on its outer wall, and a lower pressure plate 63 is slidably connected to the inner wall of the slide rail 62. A spring 64 is fixedly connected to the top of the lower pressure plate 63, and the top of the spring 64 is fixedly connected to the inner top of the slide rail 62.

[0019] The lower pressure plate 63 can apply downward pressure to the motor core, thereby assisting the workers in fixing it. Among them, the top of the turntable 3 is fixedly connected to an electric pusher 65, the outer wall of the electric pusher 65 is fixedly connected to a connecting frame 66, and the inner wall of the connecting frame 66 is rotatably connected to a bidirectional threaded rod 67.

[0020] The electric pusher 65 can adjust the position of the connecting frame 66, thereby adjusting the position of the second clamping plate 69.

[0021] Among them, the end of the bidirectional threaded rod 67 located outside the connecting frame 66 is fixedly connected to a handle 68, and the end of the bidirectional threaded rod 67 located inside the connecting frame 66 has two second clamping plates 69 that are threaded through the outer wall.

[0022] The bidirectional threaded rod 67 can rotate to drive the two second clamping plates 69 to move in opposite directions, thereby achieving a clamping effect on motor cores of different sizes.

[0023] The top of the processing table 1 is equipped with a rotating mechanism 7, the outer wall of the turntable 3 is fixedly connected with an external gear ring 71, the top of the processing table 1 is rotatably connected with a rotating shaft 72, and the top of the rotating shaft 72 is fixedly connected with a gear 73.

[0024] The rotating mechanism 7 can adjust the angle of the workpiece that needs to be corrected.

[0025] Among them, gear 73 meshes with external gear ring 71, a connecting rod 74 is fixedly connected to the top of gear 73, a knob 75 is fixedly connected to the top of connecting rod 74, and a limit hole 76 is opened on the outer wall of connecting rod 74.

[0029] This utility model provides a motor core coaxiality correction fixture, the specific working principle of which is as follows: In use, place the motor core to be calibrated above the arc-shaped receiving plate 5, move the lower pressure plate 63 upwards until it passes through the center of the motor core and one side of the motor core is in contact with the outer wall of the first clamping plate 61. Then release the force on the lower pressure plate 63. The compressed spring 64 returns to its original position, causing the lower pressure plate 63 to move downwards. This downward movement of the lower pressure plate 63 fixes the motor core above the arc-shaped receiving plate 5. Depending on the size of the motor core, rotate the handle 68. The handle 68 rotates the bidirectional threaded rod 67, which in turn rotates the two second clamping plates 69 in opposite directions. Then, turn on the electric pusher 65. The pusher 65 drives the connecting frame 66 to move, which in turn drives the second clamping plate 69 to move and fix the motor core. The first clamping plate 61 and the second clamping plate 69 cooperate to further clamp the motor core. During the calibration process, when it is necessary to rotate the motor core to adjust the angle, the limit rod 78 is pulled outward. The limit rod 78 moves out of the limit hole 76. At this time, the knob 75 is rotated. The knob 75 drives the connecting rod 74 to rotate, which in turn drives the gear 73 to rotate. The rotation of the gear 73 drives the turntable 3 to rotate through the external gear ring 71, which in turn drives the motor core to rotate, making it convenient for the staff to adjust the angle of the motor core.
