[0014] A motor stator core production and processing technology, using the motor stator core production and processing device described above, includes the following steps:

[0015] S1: First, the housing is sequentially sleeved through the fixed tube, the second arc block and the movable plate from top to bottom, and placed on the support plate. Then, the motor is started. The rotation of the motor drives the rotation of the double-headed screw, thereby driving the two movable plates to move closer to each other. At the same time, the two clamping plates are driven to move closer to each other and clamp the housing in the center.

[0016] S2: Then, the stator core body is sleeved on the side wall of the fixing tube and placed on the second arc block, and at the same time, the exposed wires at the bottom of the stator core body are in the space between the second arc block and the fixing tube, and then, the electric heating rod is started to heat the casing;

[0017] S3: After the heating is completed, the electric heating rod is turned off, and the cylinder is started, so that the piston rod drives the movable plate to move downward, and at the same time, drives the fixed tube and the second arc block to move downward. When the conical surface of the second arc block abuts against the inner wall of the casing, the second arc block can be pushed to move toward the fixed tube. At the same time, the second spring is compressed, and can push the exposed wires at the bottom of the stator core body inward to avoid contact with the heated casing, avoid damage to the casing, and ensure the quality of its production and processing;

[0018] S4: When the second arc block moves toward the direction approaching the fixed tube, the push block is driven to move synchronously through the connecting rod, so that the push pin and the inclined slot move upward, thereby pushing the first moving block and the moving rod to move upward. When the moving rod moves upward, the second moving block is driven to move upward synchronously, thereby pushing the first arc block to move away from the fixed tube through the sliding plate and the fourth sleeve. At the same time, the first spring is compressed, so that the stator core body can be adjusted to the center, and after the first arc block abuts against the inner side wall of the second arc block, when the moving rod continues to move upward, the sliding plate moves downward along the fourth sleeve, and at the same time, the fourth spring is compressed, so that the stator core body can be pressed and limited, and the stator core body and the casing can be ensured to be in a concentric state, thereby ensuring the quality of subsequent production and processing;

[0019] S5: After the second arc block is centered, when the moving plate and the second arc block continue to move downward, the moving rod continues to move upward. When the moving rod moves, the rack is driven upward by the push plate. At the same time, the third spring is compressed, thereby driving the gear to rotate counterclockwise. The rotation of the gear drives the rotating shaft to rotate, thereby driving the rotating plate to rotate, and the rotating plate is abutted against the top of the stator core body. When the moving plate and the second arc block continue to move downward, the second arc block slides downward along the inner wall of the casing, and under the push of the rotating plate, the stator core body can be pressed into the casing, making the processing more convenient and quick, and improving the processing efficiency.

[0020] S6: After the press-fitting is completed, when the second arc block moves to the bottom of the casing, the second arc block can be moved and reset in the direction away from the fixed tube under the action of the second spring. At the same time, the first arc block moves in the direction close to the fixed tube under the action of the first spring, and the rotating plate can be rotated to a vertically upward state under the action of the third spring. Then, the two clamping plates are moved away from each other through the moving mechanism. At this time, the casing and stator core body after press-fitting can be removed upwards. After removal, the movable plate is lifted by the cylinder for subsequent press-fitting operations.

Then, the motor is started, and the rotation of the motor drives the rotation of the double-headed screw, thereby driving the two movable plates to move closer to each other, and at the same time, driving the two clamping plates to move closer to each other and clamp the casing in the center. Then, the stator core body is sleeved on the side wall of the fixed tube and placed on the second arc block. At the same time, the exposed wires at the bottom of the stator core body are In the space between the second arc block and the fixed tube, then, start the electric heating rod to heat the casing. After the heating is completed, turn off the electric heating rod and start the cylinder, so that the piston rod drives the movable plate to move downward, and at the same time, drives the fixed tube and the second arc block to move downward. When the conical surface of the second arc block abuts against the inner wall of the casing, the second arc block can be pushed to move toward the fixed tube. At the same time, the second spring is compressed and can push the exposed wires at the bottom of the stator core body inward to avoid contact with the heated casing, avoid damage to the casing, and ensure the quality of its production and processing.

[0023] (2) The motor stator core production and processing device and its process are provided with a pushing mechanism and a first reset mechanism, etc. When the second arc block moves toward the fixed tube, the pushing block is driven to move synchronously through the connecting rod, so that the pushing pin and the inclined slot move upward, thereby pushing the first moving block and the moving rod to move upward. When the moving rod moves upward, it drives the second moving block to move upward synchronously, thereby pushing the first arc block to move away from the fixed tube through the sliding plate and the fourth sleeve. At the same time, the first spring is compressed, thereby being able to adjust the stator core body to the center, and after the first arc block abuts against the inner side wall of the second arc block, when the moving rod continues to move upward, the sliding plate moves downward along the fourth sleeve, and at the same time, the fourth spring is compressed, thereby being able to tighten and limit the stator core body, and being able to ensure that the stator core body and the casing are in a concentric state, thereby ensuring the quality of subsequent production and processing.

When the moving rod moves, the rack is driven upward by the push plate. At the same time, the third spring is compressed, thereby driving the gear to rotate counterclockwise. The rotation of the gear drives the rotating shaft to rotate, and then drives the rotating plate to rotate, and makes the rotating plate abut against the top of the stator core body. When the moving plate and the second arc block continue to move downward, the second arc block slides downward along the inner wall of the casing, and under the push of the rotating plate, it can The stator core body can be press-fitted into the casing, making the processing more convenient and quick, and can improve the processing efficiency. After the press-fitting is completed, when the second arc block moves to the bottom of the casing, the second arc block can be moved and reset in the direction away from the fixed tube under the action of the second spring. At the same time, the first arc block moves in the direction close to the fixed tube under the action of the first spring, and the rotating plate can be rotated to a vertically upward state under the action of the third spring. Then, the two clamping plates are moved away from each other through the moving mechanism. At this time, the casing and the stator core body after the press-fitting can be removed upward. After removal, the movable plate is lifted by the cylinder for subsequent press-fitting operations. BRIEF DESCRIPTION OF THE DRAWINGS

The rotation of the gear 701 drives the rotating shaft 602 to rotate, thereby driving the rotating plate 16 to rotate, and making the rotating plate 16 abut against the top of the stator core body 18. When the moving plate 12 and the second arc block 15 continue to move downward, the second arc block 15 slides downward along the inner wall of the casing 17, and under the push of the rotating plate 16, the stator core body 18 can be pressed into the casing 17, making the processing more convenient and quick, and improving the processing efficiency.

[0050] S6: After the press-fitting is completed, when the second arc block 15 moves to the bottom of the casing 17, the second arc block 15 can be moved and reset in the direction away from the fixed tube 13 under the action of the second spring 503. At the same time, the first arc block 14 moves in the direction close to the fixed tube 13 under the action of the first spring 403, and the rotating plate 16 can be rotated to a vertically upward state under the action of the third spring 705. Then, the two clamping plates 11 are moved away from each other through the moving mechanism 3. At this time, the casing 17 and the stator core body 18 after the press-fitting can be removed upward. After removal, the movable plate 12 is lifted by the cylinder 202 for subsequent press-fitting operations.

A motor stator core production and processing process, using a motor stator core production and processing device as claimed in any one of claim 5, characterized in that: The following steps are involved: S1: First, the housing (17) is sequentially inserted through the fixed tube (13), the second arc block (15) and the movable plate (12) from top to bottom, and is placed on the support plate (10). Next, the motor (304) is started. The rotation of the motor (304) drives the double-headed screw (303) to rotate, thereby driving the two movable plates (21) to move closer to each other, and at the same time, driving the two clamping plates (11) to move closer to each other and clamp the housing (17) in the center. S2: Next, the stator core body (18) is sleeved on the side wall of the fixing tube (13) and placed on the second arc block (15), and at the same time, the exposed wires at the bottom of the stator core body (18) are located in the space between the second arc block (15) and the fixing tube (13). Next, the electric heating rod (20) is started to heat the casing (17); S3: After the heating is completed, the electric heating rod (20) is turned off and the cylinder (202) is started, so that the piston rod (203) drives the movable plate (12) to move downward, and at the same time, drives the fixed tube (13) and the second arc block (15) to move downward. When the conical surface (1501) of the second arc block (15) abuts against the inner wall of the housing (17), the second arc block (15) can be pushed to move in a direction close to the fixed tube (13). At the same time, the second spring (503) is compressed and can push the exposed wires at the bottom of the stator core body (18) inward to prevent them from contacting with the heated housing (17) and causing damage to the wires. S4: When the second arc block (15) moves toward the direction approaching the fixed tube (13), the push block (809) is driven to move synchronously through the connecting rod (806), so that the push pin (808) and the inclined groove (807) move upward, thereby pushing the first moving block (805) and the moving rod (802) to move upward. When the moving rod (802) moves upward, it drives the second moving block (902) to move upward synchronously, thereby pushing the first arc block (14) away from the fixed tube (13) through the sliding plate (905) and the fourth set of rods (903). ), and at the same time, the first spring (403) is compressed, thereby enabling the stator core body (18) to be centered, and after the first arc block (14) and the inner side wall of the second arc block (15) abut against each other, when the moving rod (802) continues to move upward, the sliding plate (905) moves downward along the fourth sleeve (904), and at the same time, the fourth spring (906) is compressed, thereby enabling the stator core body (18) to be pressed against and limited, and ensuring that the stator core body (18) and the housing (17) are in a concentric state; S5: After the second arc block (15) is centered, when the moving plate (12) and the second arc block (15) continue to move downward, the moving rod (802) continues to move upward. When the moving rod (802) moves, the rack (704) is driven to move upward through the push plate (803). At the same time, the third spring (705) is compressed, thereby driving the gear (701) to rotate counterclockwise. The rotation of the gear (701) drives the rotating shaft (602) to rotate, thereby driving the rotating plate (16) to rotate, and causing the rotating plate (16) to abut against the top of the stator core body (18). When the moving plate (12) and the second arc block (15) continue to move downward, the second arc block (15) slides downward along the inner wall of the housing (17), and under the pushing action of the rotating plate (16), the stator core body (18) can be pressed into the housing (17); S6: After the press-fitting is completed, when the second arc block (15) moves to the bottom of the housing (17), the second arc block (15) can be moved and reset in a direction away from the fixed tube (13) under the action of the second spring (503). At the same time, the first arc block (14) moves in a direction close to the fixed tube (13) under the action of the first spring (403), and the rotating plate (16) can be rotated to a vertically upward state under the action of the third spring (705). Then, the two clamping plates (11) are moved away from each other through the moving mechanism (3). At this time, the housing (17) and the stator core body (18) after the press-fitting can be removed upward. After being removed, the movable plate (12) is lifted up by the cylinder (202) to facilitate the subsequent press-fitting operation.
