Description

Technical Field

[0001] This utility model relates to the field of machining, and in particular to a tooling for shaping the stator winding coil of a brushless motor. Background Technology

[0002] The stator of a brushless high-speed motor differs from that of a conventional single-phase or three-phase motor. The main difference is that the high-speed motor stator is composed of several blocks joined together by slots and wedges, forming a barrel shape, while the stator of a conventional single-phase or three-phase motor is a single, integral barrel shape. Therefore, the methods of stator winding and shaping are also significantly different. Taking the shaping process of a brushless high-speed motor stator as an example, it aims to prevent the coils between each stator block from becoming loose and touching each other after winding, which could lead to motor malfunctions. Traditionally, this shaping process involves manually tapping the coils with wooden blocks as pads. This method results in inconsistent tightness, easily damages the coils, causes leakage, and is inefficient. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a shaping fixture for brushless motor stator winding coils to improve shaping efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a brushless motor stator winding coil shaping fixture, including a pushing component, a winding seat and a shaping component, wherein shaping components are provided on both sides of the pushing direction of the pushing component; the winding seat is connected to the pushing component; the shaping component includes a mounting bracket and a shaping part, the shaping part is disposed on the mounting bracket, and an inclined surface is provided on one side of the shaping part parallel to the pushing direction of the pushing component.

[0005] Furthermore, the shaping component is rotatably mounted on the mounting bracket.

[0006] Furthermore, the shaping component is a roller.

[0007] Furthermore, the pushing assembly includes a pushing cylinder, a pushing seat, and a guide seat. The pushing cylinder is connected to the driving end of the pushing cylinder, and the pushing seat is provided with a winding seat. The guide seat is located in the pushing direction of the pushing cylinder, and the pushing seat is movably mounted on the guide seat.

[0008] Furthermore, the lower end of the push seat is provided with a dovetail groove, and the guide seat is provided with a slider that matches the dovetail groove.

[0009] Furthermore, the shaping component can be moved and adjusted in a direction perpendicular to the pushing direction of the pushing assembly.

[0010] Furthermore, the mounting bracket includes a fixed bracket and an adjusting bracket. The fixed bracket is provided with a guide block whose length direction is perpendicular to the pushing direction of the pushing component.

[0012] Furthermore, the mounting bracket is movable and adjustable in the height direction of the winding seat.

[0013] Furthermore, the mounting bracket is rotatably disposed on both sides of the pushing direction of the pushing component.

[0014] The beneficial effects of this utility model are as follows: during operation, the winding seat is installed on the pushing component, and the pushing component pushes the winding seat back and forth between the two shaping components.

[0019] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0020] Please refer to Figure 1 and Figure 2A brushless motor stator winding coil shaping fixture includes a pushing component 1, a winding seat 2, and a shaping component 3. The shaping component 3 is provided on both sides of the pushing direction of the pushing component 1. The winding seat 2 is connected to the pushing component 1. The shaping component 3 includes a mounting bracket 31 and a shaping element 32. The shaping element 32 is disposed on the mounting bracket 31, and an inclined surface is provided on one side of the shaping element 32 that is parallel to the pushing direction of the pushing component 1.

[0021] As can be seen from the above description, the beneficial effects of this utility model are as follows: during operation, the winding seat 2 is installed on the pushing component 1, and the pushing component 1 pushes the winding seat 2 back and forth between the two shaping components 3. The shaping component 32 of the shaping component 3 presses and shapes the coil on the winding seat 2. The design of the inclined surface on the shaping component 32 can avoid the shaping component 32 directly facing the coil on the winding seat 2 in a large area in the pushing direction of the pushing component 1, thus avoiding the pulling of the coil.

[0022] Furthermore, the shaping component 32 is rotatably mounted on the mounting bracket 31.

[0023] As can be seen from the above description, the rotatable arrangement of the shaping component 32 ensures that the coil on the winding seat 2 is pressed evenly and smoothly when the pushing component 1 is pushed.

[0024] Furthermore, the shaping component 32 is a roller.

[0025] As described above, rollers are used to apply uniform pressure to the coil on the winding base 2 to ensure its shaping effect.

[0026] Furthermore, the pushing assembly 1 includes a pushing cylinder 11, a pushing seat 12, and a guide seat 13. The pushing cylinder 11 is connected to the driving end of the pushing seat 12, and the pushing seat 12 is provided with a winding seat 2. The guide seat 13 is located in the pushing direction of the pushing cylinder 11, and the pushing seat 12 is movably disposed on the guide seat 13.

[0027] As can be seen from the above description, the guide seat 13 and the push seat 12 move together to guide the push cylinder 11.

[0028] Furthermore, the lower end of the push seat 12 is provided with a dovetail groove, and the guide seat 13 is provided with a slider that matches the dovetail groove.

[0029] As can be seen from the above description, the design of dovetail groove and slider can simultaneously limit the movement in the pushing direction and the height direction of the pushing cylinder 11, ensuring the stable pushing of the pushing cylinder 11.

[0030] Furthermore, the shaping member 32 is movable and adjustable in a direction perpendicular to the pushing direction of the pushing component 1.

[0031] As can be seen from the above description, the adjustable design of the shaping component 32 in the direction perpendicular to the pushing direction of the pushing component 1 can adapt to different coil sizes and shaping requirements.

[0032] Furthermore, the mounting bracket 31 includes a fixed bracket 311 and an adjusting bracket 312. The fixed bracket 311 is provided with a guide block whose length direction is perpendicular to the pushing direction of the pushing component 1. The adjusting bracket 312 is provided with a guide groove that matches the guide block. The adjusting bracket 312 is provided with a shaping component 32.

[0033] As described above, specifically, by adjusting the connection between the bracket 312 and the shaping component 32, the guide groove on the adjusting bracket 312 and the guide block of the fixed bracket 311 move and adjust the shaping component 32.

[0034] Furthermore, the fixed bracket 311 has a protruding fixed plate 313 at one end of the guide block, the fixed plate 313 is opposite to the adjusting bracket 312; the fixed plate 313 is locked with an adjusting bolt 314, the adjusting bolt 314 abuts against the adjusting bracket 312.

[0035] As described above, the adjustment bracket 312 can be moved and adjusted by adjusting the locking fit between the adjusting bolt 314 and the fixing plate 313.

[0036] Furthermore, the mounting bracket 31 is movable and adjustable in the height direction of the winding seat 2.

[0037] As can be seen from the above description, the adjustment setting of the mounting bracket 31 in the height direction of the winding seat 2 can improve the adaptability of the shaping component 3 to coils of different sizes and shaping requirements.

[0038] Furthermore, the mounting bracket 31 is rotatably disposed on both sides of the pushing direction of the pushing component 1.

[0039] As can be seen from the above description, by rotating the mounting bracket 31, the winding seat 2 can be rotated away from the pushing component 1 when picking up or putting down the mounting bracket 31, thus avoiding space constraints during operation.

[0051] In summary, the brushless motor stator winding coil shaping fixture provided by this utility model involves installing the winding seat on the pushing component during operation. The pushing component then pushes the winding seat back and forth between the two shaping components. The shaping component uses its shaping parts to press and shape the coil on the winding seat. The inclined surface design on the shaping parts avoids the large-area direct contact between the shaping parts and the coil on the winding seat in the pushing direction of the pushing component, thus preventing pulling on the coil.
