Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, specifically to a stator torsion wire protection device for a flat wire motor. Background Technology

[0002] The stator twisting and protective paper device for flat wire motors is a crucial part of the manufacturing process. It ensures the accuracy and safety of the stator windings during twisting. The main function of this device is to protect the positional accuracy of the insulating paper and copper wire during the twisting process, preventing damage or displacement. This device is essential for improving the production quality and performance of flat wire motor stators.

[0003] The motor stator consists of a stator core, insulating paper, and motor windings. Typically, a torsion disc is used to rotate the motor windings to achieve the torsion forming of the flat wire motor windings. During the torsion forming process, the insulating paper and the ends of the motor winding core need to be fixed. For stators with a large number of slots, using a traditional involute disc to drive the protective teeth results in insufficient space and strength for the protective teeth. Therefore, we propose a flat wire motor stator torsion protection device to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a stator torsion protection device for flat wire motors, so as to solve the problem mentioned in the background art that when the motor winding is torsion formed, it is necessary to fix the insulating paper and the end of the motor winding core. For stators with a large number of slots, the use of traditional involute discs to drive the protective teeth will result in insufficient space and insufficient strength for the protective teeth.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stator torsion wire protection device for a flat wire motor, comprising a fixing base;

[0006] Also includes:

[0007] An Archimedes spiral disk is installed inside the upper part of a fixed base. A tooth-protecting guide disk is provided above the Archimedes spiral disk, and a tooth-protecting body is provided at the upper end of the tooth-protecting guide disk. The motor stator winding is installed in the middle of the tooth-protecting body.

[0008] Preferably, a servo motor is provided on one side of the bottom of the fixed base, and a gear set is provided on one side of the inside of the fixed base. The gear set is meshed and connected to the Archimedes spiral disk, and the servo motor is connected to the gear set.

[0009] Preferably, the inner side of the tooth protector body is provided with insulating paper.

[0010] Preferably, a cam follower is provided between the Archimedes spiral disk and the tooth protector body.

[0011] Preferably, the tooth width of the tooth protector body is at least 0.5 mm larger than the winding width of the flat wire motor.

[0012] Preferably, the inter-tooth depth of the tooth protector body is at least twice as large as the winding width of the flat wire motor.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: When a workpiece needs to be positioned, the motor stator is placed at the center of the protective tooth, and the servo motor drives the gear set to rotate. The gear drives the Archimedean spiral disk to rotate. Through the rotation of the Archimedean spiral disk, the protective tooth can move radially along the protective tooth guide disk. After the protective tooth moves to the positioning position, the protective tooth fixes the insulating paper and the end of the motor winding core when the motor winding is twisted and formed. The spiral disk is an application of the Archimedean spiral to disc-shaped mechanical parts. Equally spaced Archimedean spiral grooves are machined inside the disk. The trajectory of the point moving within the spiral disk groove is the Archimedean spiral. The spiral disk, as a transmission link in mechanical transmission, has the ability to output a constant angular velocity and has excellent transmission characteristics. In the Archimedean spiral drive mechanism, when the spiral rotates, pressure is generated on both sides, causing the object to displace in a direction perpendicular to the spiral axis, thereby generating continuous lift. Using the Archimedean spiral disk can solve the problems of insufficient space and strength of the protective tooth. Attached Figure Description

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] This utility model provides a stator torsion protection device for flat wire motors, which includes a fixed base 2. The main problem this utility model solves is that when the torsion process of flat wire motor stator windings requires wire and paper protection, the traditional involute disc drive for protective teeth in stators with a large number of slots results in insufficient space and strength for the protective teeth.

[0021] For the device provided by this utility model, please refer to Figure 1-4 The following is a detailed introduction.

[0022] Archimedes spiral disk 4 is installed inside the upper part of the fixed base 2. A tooth-protecting guide disk 5 is positioned above the Archimedes spiral disk 4, and a tooth-protecting body 6 is positioned above the tooth-protecting guide disk 5. A motor stator winding 7 is installed in the middle of the tooth-protecting body 6. A servo motor 1 is positioned on one side of the bottom of the fixed base 2, and a gear set 3 is positioned on one side inside the fixed base 2. The gear set 3 is meshed with the Archimedes spiral disk 4 for transmission. The servo motor 1 is connected to the gear set 3. When positioning the workpiece is required, the motor stator is placed at the center of the tooth-protecting guard. The servo motor 1 drives the gear set 3 to rotate, which in turn drives the Archimedes spiral disk 4 to rotate. The rotation of the Archimedes spiral disk 4 allows the protective teeth to move radially along the protective tooth guide disk 5. After the protective teeth are positioned, they fix the insulating paper 9 and the end of the motor winding core during the twisting process. Insulating paper 9 is provided on the inner side of the protective tooth body 6. A cam follower 8 is provided between the Archimedes spiral disk 4 and the protective tooth body 6. The main function of the cam follower 8 is to convert the rotational motion of the cam into linear or angular motion. During the twisting process of the flat wire motor stator, the cam follower 8 can receive the power input from the cam and convert it into the required linear or angular motion, thereby driving the relevant components in the paper and wire protection device to move precisely.

[0023] This invention is installed between a fixing mechanism and a torsion disc to determine the torsion position of the flat wire motor winding. The invention includes a tooth guide disc and a tooth body. The tooth guide disc is connected to the fixing mechanism, and the tooth body is disposed on the tooth guide disc. The tooth body and the tooth guide disc are movably connected via an Archimedean spiral disc. The tooth can move radially along the tooth guide disc. The tooth body has a toothed structure: a toothed structure is provided on the torsion disc. The tooth width of these structures should be at least 0.5 mm larger than the winding width of the flat wire motor, and the tooth depth should be at least twice the winding width of the flat wire motor. These toothed structures will help fix and torsion the motor winding.
