Technical Field

[0001] This utility model belongs to the field of motor processing technology, and specifically relates to a tooling for winding and shaping small-sized self-adhesive wire coils for motors. Background Technology

[0002] The motor coil generates a magnetic field when current flows through it, causing the rotor to rotate continuously. The winding methods for motor coils vary depending on different needs and operating conditions. Current tooling cannot solve the problem of directly winding and shaping small-sized self-adhesive wire coils on the iron core, requiring further improvement. Utility Model Content

[0003] This invention provides a tooling for winding and shaping small-sized coils of self-adhesive motor wires, which can solve the problems existing in the prior art.

[0004] To solve the above problems, the technical solution provided by this utility model is as follows:

[0005] This utility model embodiment provides a tooling for winding and shaping a small-sized self-adhesive wire coil for an electric motor, including a winding mold core (1), a short bolt (2), a first front baffle (3), a second front baffle (4), a rear baffle (5), a washer (6), a nut (7), a first shaping plate (8), a second shaping plate (9), and a long bolt (10).

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0017] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model embodiment provides a tooling for winding and shaping a small-sized self-adhesive wire coil for a motor, including a winding mold core 1, a short bolt 2, a first front baffle 3, a second front baffle 4, a rear baffle 5, a washer 6, a nut 7, a first shaping plate 8, a second shaping plate 9, and a long bolt 10.

[0018] like Figure 2 As shown, the winding die core 1 includes a front cylinder 1-1, a middle cylinder 1-2, a cuboid die core 1-3, and a rear cylinder 1-4. The front cylinder 1-1 is connected to one side of the cuboid die core 1-3 via the middle cylinder 1-2. The rear cylinder 1-4 is connected to the other side of the cuboid die core 1-3. The front cylinder 1-1 is provided with a keyway 1-5 for fixed connection to the winding machine.

[0019] Figure 3 Combination Figure 1 The rectangular mold core 1-3 is used to fit the coil 11. The first shaping plate 8 and the second shaping plate 9 are connected to the left and right sides of the coil 11. The first shaping plate 8 and the second shaping plate 9 are connected by 4 long bolts 10. The first front baffle 3 and the second front baffle 4 are connected to the upper and lower sides of the coil 11. The first front baffle 3 and the second front baffle 4 are connected by 2 short bolts 2. The tail cylinder 1-4 is connected to the rear baffle 5 through the washer 6 and the nut 7. The rear baffle 5 is fitted to the rear side of the coil 11.

[0020] The fixture for winding and shaping the small-sized self-adhesive coil of the motor in this embodiment has a simple structure and is easy to operate. The winding mold core 1 is an integrated design: the front cylinder 1-1 is fastened to the winding machine through a keyway, providing mechanical power for winding. The middle cylinder 1-2 is tightly fixed to the first front baffle 3 and the second front baffle 4 by short bolts, providing an end face for coil winding. The split design of the front baffle facilitates coil demolding and winding installation after coil baking and shaping. The cuboid mold core 1-3 is the winding point of the mold core, and its shape and size are consistent with the required small-sized coil 11. The two sides of the cuboid mold core 1-3 provide positioning planes for the first front baffle 3 and the second front baffle 4. For example, one side of the cuboid mold core 1-3 is 1-31, and the other side is 1-32. The rear baffle 5 is tightly fixed to the threaded part of the tail cylinder 1-4 by a washer 6 and a nut 7, providing another end face for coil winding.

[0021] The first shaping plate 8 and the second shaping plate 9 shape the wound coil 11 by tightening four long bolts 10, preventing deformation of the coil 11 due to the ductility of the copper wire after it is removed from the winding machine, thus ensuring the coil's external dimensions. A first preset small gap is provided on the contact surfaces of the first shaping plate 8 and the second shaping plate 9, and a second preset small gap is provided on the contact surfaces of the first front baffle 3 and the second front baffle 4. The size of the first and second preset small gaps is related to the diameter of the copper wire in the wound coil. If the gap is too small, installation will be difficult; if the gap is too large, the copper wire near the front and rear baffles will not be properly shaped. The single-sided gap value can be considered to be in the range of 0.1mm to half the diameter of the copper wire. That is, the first and second preset small gaps are 0.1mm to half the diameter of the copper wire in the coil 11.

[0022] This utility model embodiment also provides a method for winding and shaping small-sized self-adhesive wire coils, specifically including the following steps:

[0023] Step 1, the coil winding and shaping fixture includes ten parts: winding mold core 1, short bolt 2, first front baffle 3, second front baffle 4, rear baffle 5, washer 6, nut 7, first shaping plate 8, second shaping plate 9 and long bolt 10.

[0024] Step 2: The front cylindrical body 1-1 of the winding mold core 1 is tightly fixed to the single-axis winding machine through the keyway 1-5, providing mechanical power for winding; the two sides of the cuboid mold core 1-3 of the winding mold core 1 provide positioning planes for the first front baffle 3, the second front baffle 4 and the rear baffle 5, and provide winding contour surface for the coil 11. The outer contour of the cuboid mold core 1-3 is consistent with the shape and size of the inner contour of the required coil 11.

[0025] Step 3: The first front baffle 3 and the second front baffle 4 are tightly attached to the side of the cuboid mold core 1-3 by short bolts 2; the rear baffle 5 is tightly attached to the other side of the cuboid mold core 1-3 by gaskets 6 and nuts 7, providing forming conditions for the coil 11.

[0026] Step 4: After coil 11 is wound, due to the ductility of copper wire, the coil's external dimensions will increase, causing interference with other components during installation. The first shaping plate 8 and the second shaping plate 9 use long bolts 10 to shape the wound coil 11, ensuring its external dimensions. Small gaps are provided on the sides of the first shaping plate 8 and the second shaping plate 9, and on the contact surfaces of the front and rear baffles. The size of these gaps is related to the diameter of the copper wire; the gap value on one side can be considered to be in the range of 0.1mm to half the diameter of the copper wire.

[0027] Step 5: After the coil 11 is wound, remove it from the winding machine and install the first shaping plate 8 and the second shaping plate 9. Then, put the wound coil into an oven with a certain temperature set for baking. The set temperature value is related to the temperature resistance level of the self-adhesive wire. After a certain baking time, it will be formed. Note that the copper wire used is self-adhesive wire. After the coil 11 is formed, demold it. At this time, the purpose of winding and shaping the self-adhesive wire coil can be achieved.

[0028] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
