Description

Positioning fixture for stator winding of tubular motor Technical Field

[0001] This utility model relates to the field of motor stator processing technology, and in particular to a positioning fixture for winding tubular motor stators. Background Technology

[0002] Due to the elongated hole structure of the stator core in tubular motors, traditional manual winding methods suffer from low efficiency and easy damage to insulation, necessitating the use of specialized tools and optimized processes. This new method employs winding along the axial direction of the stator core's inner hole. The tool head is designed with a retractable guide structure, enabling precise control of the coil embedding angle and depth. During the winding process, a positioning fixture is used to position the stator, facilitating subsequent winding operations.

[0003] Previous positioning fixtures for winding tubular motor stators have the following drawbacks: 1. They cannot simultaneously position and clamp multiple tubular motor stators, are inconvenient for automatic rotation feeding, have low winding efficiency, and are not easy to adjust the platform to be level, thereby vertically clamping the tubular motor stators for precise winding operation. Therefore, those skilled in the art have provided positioning fixtures for winding tubular motor stators to solve the problems mentioned in the background art. Summary of the Invention

[0004] The main objective of this invention is to provide a positioning fixture for stator winding of a tubular motor, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Positioning fixture for stator winding of tubular motor, including electric turntable, L-shaped mounting plate and adjustment platform;

[0007] The top outer edge of the electric turntable is equipped with connecting bearings via bearing seats. A leveling screw is fitted inside the rotating ring of the connecting bearing, and a leveling nut is fitted at the top of the leveling screw. An adjustment platform is welded to the top of the leveling nut. Support columns are installed at equal intervals on the top outer edge of the adjustment platform via fixed plates. Electric cylinders are installed on the outer side of each support column via arc-shaped positioning plates. A circular plate is welded to the top of each support column. A reserved groove is opened on the outer side of each circular plate, and a U-shaped clamping piece is welded in the reserved groove. A linkage plate is connected to the U-shaped clamping piece via a rotating shaft. An arc-shaped clamping plate is connected to one side of the top of the linkage plate via a connecting rod.

[0008] As a further embodiment of this utility model: a motor controller is installed on one side of the electric turntable by screws. The output end of the motor controller is electrically connected to the input end of the drive motor of the electric turntable through a wire. The motor controller automatically controls the rotation angle of the electric turntable, and the electric turntable drives the adjustment platform to rotate to different positions.

[0009] As a further improvement of this utility model, the inner side of the arc-shaped clamping plate is provided with integrally formed anti-slip protrusions.

[0010] As a further improvement of this utility model, a level is installed on the outer side of the adjustment platform at equal intervals by screws.

[0011] As a further improvement of this utility model: an extension plate is welded to the bottom end of the linkage plate, and the output shaft of the electric cylinder is connected to one side of the bottom end of the extension plate by screws.

[0012] As a further improvement of this utility model: an L-shaped mounting plate is bolted to the bottom outer side of the electric turntable. The L-shaped mounting plate has mounting screw holes, and the mounting screw holes and matching bolts on the L-shaped mounting plate facilitate the installation of the overall positioning fixture on the reference table.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Place the tubular motor stator between the arc-shaped clamping plates, turn on the electric cylinder power supply, and make the electric cylinder push one side of the bottom end of the extension plate, thereby causing the linkage plate to rotate inward. Finally, the arc-shaped clamping plates clamp and fix the tubular motor stator, realizing the simultaneous positioning and clamping of multiple tubular motor stators. The tubular motor stator is suspended and clamped to avoid affecting the stator winding operation.

[0015] 2. The rotation angle of the electric turntable is automatically controlled by the motor controller. The electric turntable drives the adjustment platform to rotate to different positions, thereby automatically feeding the clamped tubular motor stator and improving the winding efficiency. The level is used to check whether the adjustment platform is level. When it is not level, the leveling screw at the bottom of the adjustment platform can be used to adjust the adjustment platform to be level, so that the positioning fixture is in a vertical state, which makes it easy to vertically clamp the tubular motor stator and make it accurate for winding operation.

Electric cylinders 12 are installed on the outer side of the support columns 11 through arc-shaped positioning plates. A circular plate 18 is welded to the top of the support columns 11. A reserved groove is opened on the outer side of the circular plate 18, and a U-shaped clamping piece 14 is welded in the reserved groove. A linkage plate 15 is connected to the U-shaped clamping piece 14 through a rotating shaft. An arc-shaped clamping plate 16 is connected to one side of the top of the linkage plate 15 through a connecting rod 17.

[0023] One side of the electric turntable 1 is equipped with a motor controller 2 by screws. The output end of the motor controller 2 is electrically connected to the input end of the drive motor of the electric turntable 1 through a wire. The motor controller 2 automatically controls the rotation angle of the electric turntable 1, and the electric turntable 1 drives the adjustment platform 10 to rotate to different positions.

[0024] The inner side of the arc-shaped clamping plate 16 is provided with integrally formed anti-slip protrusions 19; the anti-slip protrusions 19 improve the anti-slip effect of the arc-shaped clamping plate 16 and provide high clamping stability.

[0025] Among them, the leveling platform 10 is equipped with level instruments 8 at equal intervals by screws on the outside; the level instruments 8 are used to facilitate the detection of whether the leveling platform 10 is level.

[0026] The bottom end of the linkage plate 15 is welded with an extension plate 13, and the output shaft of the electric cylinder 12 is connected to one side of the bottom end of the extension plate 13 by screws; the electric cylinder 12 pushes one side of the bottom end of the extension plate 13, thereby causing the linkage plate 15 to rotate inward.

[0028] The working principle of this utility model is as follows: The mounting screw holes 3 and matching bolts on the L-shaped mounting plate 4 facilitate the installation of the overall positioning fixture on the reference platform. The tubular motor stator is placed between the arc-shaped clamping plates 16. The power to the electric cylinder 12 is turned on, causing the cylinder 12 to push one side of the bottom end of the extension plate 13, thereby causing the linkage plate 15 to rotate inward. Ultimately, the arc-shaped clamping plates 16 clamp and fix the tubular motor stator, achieving simultaneous positioning and clamping of multiple tubular motor stators. The tubular motor stators are suspended in the air, avoiding interference with the stator winding operation. Anti-slip protrusions are used to further enhance the performance. 19.
