[0002] The stator is the stationary part of the motor. The stator consists of three parts: the stator core, the stator winding and the frame. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by the magnetic lines of force in the rotating magnetic field to generate (output) current. After the stator is produced, the inspection personnel generally place the stator on the work station and need to detect defects in specific positions through rotation positioning. There are currently two ways to position the stator: one is to place the stator on the platform and drive the platform to rotate through the motor; the other is to clamp the stator with a clamp, rotate it in the air, and then drop it onto the platform.

[0003] However, in the first method, the stator is placed on the platform and the platform is rotated by a motor, and the stator will slip under the action of inertia, causing angular deviation; in the second method, the stator is clamped by a clamp, rotated in the air, and then dropped onto the platform, which will cause scratches or scratches on the product surface.

[0004] Therefore, it is necessary to provide a new technology for automatically rotating the inner support positioning of the stator to solve the above technical problems. Utility Model Content

The technology for automatic rotation of the stator internal support for positioning includes: an annular plate 1. In order to support the device and make it more convenient for people to operate the device, four support legs are fixedly installed at the bottom of the annular plate 1, and the bottom ends of the four support legs are respectively fixedly sleeved with anti-skid sleeves. The friction between the support legs and the ground is increased by the anti-skid sleeves, so that the device can be placed on the ground more stably. A rotating platform 2 is rotatably installed in the annular plate 1. In order to rotatably install the rotating platform 2 on the annular plate 1, a rotating bearing is fixedly installed in the annular plate 1. The rotating platform 2 penetrates the rotating bearing and is fixedly connected to the inner wall of the rotating bearing. The bearing makes the rotation of the rotating platform 2 on the annular plate 1 more stable. A through hole 3 is opened on the rotating platform 2. Two L-shaped connecting plates 9 are fixedly installed at the bottom of the annular plate 1. The two L-shaped connecting plates 9 A mounting plate 10 is fixedly installed on one side close to each other, and a rotating motor 11 is fixedly installed on the top of the mounting plate 10. The rotating motor 11 is used to drive the stator to perform rotation positioning detection. A protective barrel 4 is fixedly installed on the output shaft of the rotating motor 11, and the protective barrel 4 is fixedly connected to the rotating platform 2. An electric push rod 5 is fixedly installed on the inner wall of the bottom of the protective barrel 4. A truncated cone-shaped connecting plate 6 is fixedly installed on the output shaft of the electric push rod 5. A threaded groove is provided on the top of the truncated cone-shaped connecting plate 6. An air expansion shaft 7 is provided in the through hole 3. The air expansion shaft 7 is driven to move into the inner hole of the stator by extending the output shaft of the electric push rod 5. The air expansion shaft 7 is opened and inflated to be in close contact with the inner wall of the stator. A connecting screw 8 is fixedly installed on the bottom of the air expansion shaft 7, and the bottom end of the connecting screw 8 extends into the threaded groove and rotates with the inner wall of the threaded groove.

[0021] In order to ensure that the two semicircular plates 17 are always tightly fitted together without being affected by other external forces, the through hole 3 is blocked, thereby preventing external dust from falling into the through hole 3 and adhering to the air shaft 7, thereby affecting the service life of the air shaft 7, a circular receiving groove 12 is provided on the inner wall of the through hole 3, and two mounting grooves 13 are provided on the inner wall of the circular receiving groove 12. Compression springs 14 are fixedly installed on the inner walls of one side of the two mounting grooves 13. In order to improve the service life of the compression springs 14, the two compression springs 14 are tin-plated springs, and stabilizing plates 15 are fixedly installed on one end of the two compression springs 14, and the two stabilizing plates 15 are respectively slidably connected to the corresponding mounting grooves 13. Connecting rods 16 are fixedly installed on the outer walls of one side of the two stabilizing plates 15, and semicircular plates 17 are fixedly installed on the ends of the two connecting rods 16 away from each other, and semi-conical grooves are respectively provided on the top and bottom inner walls of the two semicircular plates 17.

[0022] In order to limit the stabilizing plate 15 and make it more stable when moving, so as to make the two semicircular plates 17 more stable when assembled together, two limiting grooves are respectively opened on the inner walls of the two mounting grooves 13, and the two sides of the two stabilizing plates 15 extend into the two limiting grooves respectively and are slidably connected with the inner walls of the two limiting grooves respectively.

[0023] The working principle of the technology of automatic rotation and internal support positioning of the stator provided by the utility model is as follows: in the initial state, the compression spring 14 is in a compressed state, and the two compression springs 14 make the two semicircular plates 17 always fit closely together without being affected by other external forces, so as to block the through hole 3, thereby preventing external dust from falling into the through hole 3 and adhering to the air expansion shaft 7, thereby affecting the service life of the air expansion shaft 7. When it is necessary to use this device, the stator to be detected is placed on the rotating platform 2, so that the through hole 3 is located directly below the stator, and the electric push rod 5 is started. The output shaft of the electric push rod 5 is extended to drive the truncated cone-shaped connecting plate 6 to move upward, and the truncated cone-shaped connecting plate 6 moves upward to drive the air expansion shaft 7 to move upward, and the air expansion shaft 7 moves and contacts the semicircular plate 17. Since the bottom and top of the semicircular plate 17 are respectively provided with semi-conical grooves, the surface where the semicircular plate 17 contacts the air expansion shaft 7 is an inclined surface, and the thrust of the air expansion shaft 7 on the semicircular plate 17 is perpendicular to the inclined surface. It can be known from mechanical analysis The thrust perpendicular to the inclined plane can be decomposed into a horizontal force and a vertical force, and the horizontal force will push the two semicircular plates 17 away from each other and enter the circular receiving groove 12 to open the through hole 3, so that the gas expansion shaft 7 enters the inner hole of the stator, and then the gas expansion shaft 7 opens and inflates to contact the inner hole of the stator all around, and is in close contact with the inner wall of the stator. As the rotating motor 11 rotates, the protective barrel 4 rotates, the protective barrel 4 rotates and the rotating platform 2 rotates, and the rotating platform 2 rotates and drives the stator to perform rotation positioning detection. Since the device clamps the inside of the stator through the expansion of the gas expansion shaft 7, the stator will not slip under the action of inertia, causing angular deviation and scratching or scratching the surface of the stator. When the device is used, the output shaft of the electric push rod 5 retracts and drives the truncated cone-shaped connecting plate 6 and the gas expansion shaft 7 to move downward into the through hole 3, and the compression spring 14 pushes the two semicircular plates 17 to fit tightly together to block the through hole 3, thereby protecting the gas expansion shaft 7 from dust.

[0024] Compared with the related art, the technology of automatic rotation inner support positioning of the stator provided by the utility model has the following beneficial effects:

[0025] The utility model provides a technology for automatically rotating the stator and supporting the positioning. Two compression springs 14 are used to keep the two semicircular plates 17 tightly fitted together without being affected by other external forces, so as to block the through hole 3, thereby preventing external dust from falling into the through hole 3 and adhering to the air expansion shaft 7, thereby affecting the service life of the air expansion shaft 7. The stator to be inspected is placed on the rotating platform 2, and the air expansion shaft 7 is driven to move and contact the semicircular plates 17 through the extension of the output shaft of the electric push rod 5, so as to push the two semicircular plates 17 away from each other and enter the circular receiving groove 12 to open the through hole 3, so that the air expansion shaft 7 can enter. The air shaft 7 is opened to inflate and is in close contact with the inner wall of the stator. The stator is driven by the rotating motor 11 to perform rotational positioning detection. Since the device clamps the inside of the stator by the expansion of the air shaft 7, the stator will not slip under the action of inertia, causing angular deviation and scratches or scratches on the surface of the stator.
