Description

Technical Field

[0001] The utility model generally relates to the technical field of rotor winding machines, and more specifically, to a winding die head assembly and a winding device. Background Art

[0002] An excitation rotor generally includes a rotor core and a rotor winding wound around the rotor core. When a manufacturer produces a rotor core, a high-speed stamping machine tool is generally used for processing, and then a copper wire is wound around the rotor core by a special winding device to form a rotor winding. The quality of the rotor is closely related to the processing quality of the rotor core and the winding quality of the rotor winding.

[0003] One end of the existing winding die head close to the rotor is a sharp corner end. The copper wire on the winding device is guided into the winding groove of the rotor by the smooth outer side surface to wind the copper wire around the rotor. However, when the copper wire passes through the transition position of the winding die head, the bouncing amplitude of the copper wire is relatively large, which easily wears and scratches the copper wire, resulting in the copper wire having holes, thus affecting the finished product quality. Summary of the Utility Model

[0004] The winding die head assembly and the winding device provided by the utility model can reduce winding bounce to reduce the risk of holes.

[0005] According to a first aspect of the utility model, a winding die head assembly is provided for guiding a winding to a workpiece to be wound. The winding die head assembly includes:

[0006] A main body;

[0007] A wire arranging member connected to the main body. The wire arranging member includes a protruding portion, and the protruding portion is disposed on a side of the main body facing the workpiece to be wound;

At least one side of the protruding portion along the second direction is provided with a first arc structure. The first direction and the second direction are perpendicular to each other, and the first direction is the axial direction of the main body.

[0009] In some embodiments, an edge of the protruding portion away from the main body is a second arc structure.

[0010] In some embodiments, along the second direction and from the middle of the protruding portion to both sides, the distance between the protruding portion and the main body along the first direction gradually decreases.

[0011] In some of these embodiments, at least one side of the main body along the third direction is provided with an avoidance groove corresponding to the protruding portion, and the avoidance groove is used to avoid the winding;

[0012] Wherein, the second direction and the third direction are perpendicular to each other.

[0013] In some of these embodiments, the groove wall of the avoidance groove is a third arc structure.

[0014] In some of these embodiments, the connection position between the groove wall of the avoidance groove and the main body is a fourth arc structure.

[0015] In some of these embodiments, the main body is provided with a guiding inclined surface, and along the second direction, the guiding inclined surface is arranged on both sides of the avoidance groove and the protruding portion.

[0016] In some of these embodiments, the main body is a conical structure, and the small end of the conical structure faces the workpiece to be wound.

[0017] In some of these embodiments, the main body is provided with a mounting through hole, and the protruding portion passes through the mounting through hole.

[0018] In some of these embodiments, it further includes:

[0019] A connecting piece, which passes through the wire arranging piece and the main body along the first direction;

[0020] An elastic piece, which is sleeved outside the connecting piece and arranged between the wire arranging piece and the main body.

[0021] According to the second aspect of the present invention, an embodiment of the present invention further provides a winding device, which includes a winding driving assembly and the above-mentioned winding die head assembly, the winding driving assembly is connected to the winding die head assembly, and the winding driving assembly can drive the winding die head assembly to rotate.

[0022] An embodiment of the present invention has the following advantages or beneficial effects:

[0023] The wire winding die head assembly provided in this embodiment enables the wire to move from the main body through the protruding part along the first direction and move towards or away from the workpiece to be wire-wound, thereby realizing the conveying process of the wire to the workpiece to be wire-wound. The wire slides between the main body and the protruding part with the first direction as the axis, so that while the wire is continuously conveyed, it is also wound around the workpiece to be wire-wound by rotating, thereby completing the wire-winding process. By providing a first arc-shaped structure on at least one side of the protruding part along the second direction, the first arc-shaped structure serves as a transition position for the wire to slide between the main body and the protruding part.

[0045] This embodiment provides a winding device, as Figure 1 shown, the winding device includes a winding drive assembly 100 and a winding die head assembly 300. The winding drive assembly 100 is connected to the winding die head assembly 300. The winding drive assembly 100 can drive the winding die head assembly 300 to rotate, and the winding die head assembly 300 is used to guide the winding to a workpiece to be wound (not shown in the figure).

[0046] Among them, the winding can be copper wire, and the diameter of the winding is about 0.3 mm to 0.6 mm.

[0047] Among them, the workpiece to be wound includes but is not limited to a fan stator, and can also be other coils that need to be wound, etc.

[0048] When the winding drive assembly 100 drives the winding die head assembly 300 to rotate, the winding die head assembly 300 drives the continuously conveyed winding to rotate continuously outside the winding die head assembly 300, and guides it to the workpiece to be wound through the winding die head assembly 300, so as to finally wind the winding around the outside of the workpiece to be wound.

[0049] In one embodiment, the winding drive assembly 100 includes a rotation drive source (not shown in the figure) and an output rod (not shown in the figure). The rotation drive source can be a rotation motor. The output end of the rotation drive source is connected to the winding die head assembly 300 through the output rod to drive the winding die head assembly 300 to rotate around the output rod.

[0050] In one embodiment, as Figure 1As shown, the winding device further includes a lead wire assembly 200. The lead wire assembly 200 is arranged outside the winding die head assembly 300, and the lead wire assembly 200 serves to guide the winding.

[0051] Specifically, the lead wire assembly 200 includes a housing 201, a lead wire seat 202, and a guide cylinder 203. The housing 201 has a hollow structure. The housing 201, the winding drive assembly 100, and the winding die head assembly 300 are coaxially arranged. At least one end of the housing 201 in the axial direction of the housing 201 is provided with an avoidance opening for avoiding the winding drive assembly 100 and the winding die head assembly 300. The lead wire seat 202 is arranged on the outer wall of the housing 201 and is used for installing and fixing the guide cylinder 203. The winding can pass through the central hole of the guide cylinder 203, and the guide cylinder 203 serves to limit and guide the winding. Among them, the guide cylinder 203 is rotatably connected to the lead wire seat 202 through a first rotating shaft for adjusting the rotation angle of the guide cylinder 203 relative to the lead wire seat 202, so as to achieve the purpose of adjusting the angle of the guide cylinder 203 for conveying the winding.

[0052] As Figure 1 shown, the lead wire assembly 200 further includes a guide wheel 204. The guide wheel 204 is rotatably connected to the lead wire seat 202 through a second rotating shaft. The winding can be wound around the guide wheel 204 and then pass through the guide cylinder 203. As the winding moves, it drives the guide wheel 204 to rotate relative to the lead wire seat 202. The guide wheel 204 serves to assist the winding in changing the transmission direction, and to a certain extent, the guide wheel 204 also achieves the effect of tensioning the winding.

[0053] This embodiment also provides a winding die head assembly 300 for guiding the winding to the workpiece to be wound. As Figure 1 - Figure 2 shown, the winding die head assembly 300 includes a main body 1, and the winding is guided and conveyed to the workpiece to be wound through the main body 1.

[0054] Among them, the main body 1 has a conical structure, and the small-mouth end of the conical structure is arranged towards the workpiece to be wound. In this way, the small-mouth end of the main body 1 serves to gather the winding and can guide the winding to the workpiece to be wound with a relatively small size.

[0055] Among them, the main body 1, the housing 201 of the lead wire assembly 200, and the winding drive assembly 100 are coaxially arranged. Define the axial direction of the main body 1 as the first direction, which is marked with D1. The radial direction of the housing 201 is the second direction, which is the width direction of the main body 1 and is marked with D2. The third direction is the height direction of the main body 1 and is marked with D3. The first direction, the second direction, and the third direction are perpendicular to each other pairwise. The first direction, the second direction, and the third direction only represent spatial directions and have no substantial meaning.

[0056] As Figure 1 - Figure 2As shown, the wire winding die head assembly 300 further includes a wire arranging member 2. The wire arranging member 2 is connected to the main body 1. The wire arranging member 2 includes a protruding portion 21, and the protruding portion 21 is disposed on a side of the main body 1 facing the workpiece to be wire-wound. Wherein, the wire is configured to be able to pass through the protruding portion 21 from the main body 1 and move in a first direction and in a direction close to or away from the workpiece to be wire-wound, and the wire can slide between the main body 1 and the protruding portion 21 with the first direction as an axis, so that the wire is wound around the workpiece to be wire-wound.

[0057] In the wire winding die head assembly 300 provided in this embodiment, the wire can pass through the protruding portion 21 from the main body 1 and move in a first direction and in a direction close to or away from the workpiece to be wire-wound, realizing the conveying process of the wire to the workpiece to be wire-wound. The wire slides between the main body 1 and the protruding portion 21 with the first direction as an axis, so that while the wire is continuously conveyed, it is also wound around the workpiece to be wire-wound in a rotating manner to complete the wire winding process.

[0058] By disposing the protruding portion 21 of the wire arranging member 2 on a side of the main body 1 facing the workpiece to be wire-wound, that is, the protruding portion 21 protrudes from the main body 1, when the wire moves from the main body 1 to the protruding portion 21, a "step-up speed" can be performed once, which is beneficial for the wire to be quickly wound onto the workpiece to be wire-wound subsequently.

[0059] It should be particularly noted that under the combined action of the main body 1 and the wire arranging member 2 of the wire winding die head assembly 300, the final moving direction of the wire is along the first direction and from the main body 1 through the protruding portion 21 to the workpiece to be wire-wound, realizing the wire feeding process while also realizing the wire winding process of the workpiece to be wire-wound. Since the guiding cylinder 203 of the lead wire assembly 200 has a certain inclination angle and the main body 1 of the conical structure has an inclined outer wall surface, the conveying direction of the wire is not exactly the first direction when passing through the guiding cylinder 203 and the outer wall surface of the main body 1, but the X direction, and the X direction has a certain included angle with the first direction and the second direction. However, the acting force of the outer wall surface of the main body 1 on the wire in the X direction can be decomposed into a first acting force F1 along the first direction and a second acting force F2 along the third direction. The first acting force F1 provides a driving force for the wire to move in the first direction, and the second acting force F2 provides a downward pressure for the wire in the third direction, so that the wire contacts the main body 1 or the protruding portion 21 to avoid the wire position from deviating.

[0060] When the wire slides between the main body 1 and the protruding portion 21 with the first direction as an axis, when the wire passes through the transition position between the main body 1 and the protruding portion 21, it is easy to bounce, resulting in perforations in the wire. For example, the number of perforations in the wire is greater than 20 every about 6 meters, affecting the finished product quality.

[0061] For this reason, as Figure 2 shown, the protruding portion 21 provided in this embodiment is provided with a first arc structure 211 on at least one side in the second direction.

[0062] Exemplarily, the first arc-shaped structure 211 is disposed on the left side of the protruding portion 21 along the second direction, or the first arc-shaped structure 211 is disposed on the right side of the protruding portion 21 along the second direction, or two first arc-shaped structures 211 are respectively disposed on the left and right sides of the protruding portion 21 along the second direction.

[0063] By providing the first arc-shaped structure 211 on at least one side of the protruding portion 21 along the second direction, the first arc-shaped structure 211 serves as an intermediate transition position for the wire to slide between the main body 1 and the protruding portion 21. Since the first arc-shaped structure 211 has no sharp corners, the transition is smooth and has good smoothness, reducing the risk of the wire bouncing and the risk of the wire breaking through the hole due to collision damage.

[0064] Adopting this method, the number of wire break-through holes is less than 8 for every about 6 meters of wire winding, meeting the wire winding specifications and effectively improving the finished product quality.

[0065] In one embodiment, as Figure 2 - Figure 3 shown, the edge of the protruding portion 21 away from the main body 1 is the second arc-shaped structure 212. For example, the radius of the second arc-shaped structure 212 is approximately 10 mm.

[0066] When the wire winds and slides between the main body 1 and the protruding portion 21 with the first direction as the axis, the wire can smoothly transition from the relatively flat side wall surface of the main body 1 to the arc surface of the second arc-shaped structure 212, reducing the risk of the wire breaking due to bouncing. When the wire is located at the protruding portion 21, since there are no sharp corners on the arc surface of the second arc-shaped structure 212, the risk of the wire being bent or damaged is avoided.

[0067] Among them, the first arc-shaped structure 211 and the second arc-shaped structure 212 of the protruding portion 21 are an integrally formed structure, reducing the processes of separate machining and assembly, saving production costs. At the same time, a smooth transition can be achieved between the first arc-shaped structure 211 and the second arc-shaped structure 212, avoiding the risk of the wire bouncing at this transition position.

[0068] In one embodiment, as Figure 4 - Figure 5 shown, along the second direction and from the middle of the protruding portion 21 to both sides, the distance between the protruding portion 21 and the main body 1 along the first direction gradually decreases.

[0069] That is, the protruding portion 21 is similar to a tongue shape. Since the distance between the middle of the protruding portion 21 and the main body 1 along the first direction is relatively large, the middle of the protruding portion 21 is closer to the workpiece to be wound. The wire can gradually transition from the relatively flat side wall surface of the main body 1 through the protruding portion 21 to the middle of the protruding portion 21, so that the wire winds in the first direction and towards the direction close to the workpiece to be wound.

[0070] Therefore, during the entire winding process, the winding smoothly slides and switches between the convex portion 21 and the main body 1, reducing the occurrence of damage due to bouncing.

[0071] Since the winding needs to move from the main body 1 to the convex portion 21 during the conveying process of the winding, if the main body 1 has an edge contour corresponding to the convex portion 21, the winding will have a large bend at the position of the edge contour, and damage is likely to occur.

[0072] For this reason, as Figure 2 - Figure 5 shown, at least one side of the main body 1 along the third direction and corresponding to the convex portion 21 is provided with an avoidance groove 11, and the avoidance groove 11 is used to avoid the winding.

[0073] The avoidance groove 11 can be used to avoid the winding, reducing the risk of the winding being bent and damaged, and to a certain extent, also reducing the contact area between the winding and the main body 1, that is, the winding can move to the convex portion 21 with less contact with the main body 1, thereby reducing the frictional force between the winding and the main body 1 and further reducing the risk of the winding being damaged.

[0074] Among them, the groove wall of the avoidance groove 11 is a third arc structure.

[0075] In this way, when the winding slides between the main body 1 and the convex portion 21 with the first direction as the axis, since the groove wall surface of the avoidance groove 11 is an arc surface, the shape of the avoidance groove 11 is approximate to the path required for the winding to slide, reducing the risk of hindering the movement of the winding, and the part of the winding located in the avoidance groove 11 can smoothly slide relative to the groove wall surface of the avoidance groove 11, reducing the risk of the winding being worn.

[0076] Exemplarily, the radius of the third arc structure is slightly larger than the radius of the convex portion 21, and the radius of the third arc structure is about 14 mm.

[0077] In one embodiment, the connection position between the groove wall of the avoidance groove 11 and the main body 1 is a fourth arc structure 14.

[0078] It can be understood that the connection position between the groove wall of the avoidance groove 11 and the main body 1 can be formed into a fourth arc structure 14 by rounding, that is, the edge of the avoidance groove 11 along the third direction has an arc surface, and when the winding moves from the main body 1 through the avoidance groove 11 to the convex portion 21, the edge of the avoidance groove 11 will not damage the winding.

[0079] In one embodiment, the main body 1 is provided with a guiding inclined surface 12, and along the second direction, the guiding inclined surface 12 is arranged on both sides of the avoidance groove 11 and the convex portion 21. Among them, the slope of the guiding inclined surface 12 is about 14°.

[0080] It can be understood that the part of the main body 1 located between the avoidance groove 11 and the protruding part 21 is an inclined wall surface. The guiding inclined surface 12 is used to guide the winding, which is beneficial for the winding to move from the main body 1 to the protruding part 21. Compared with the angular structure, the guiding inclined surface 12 can also reduce the contact time between the winding and the main body 1, and reduce the wear of the winding during the guiding process.

[0081] If the wire arranging member 2 covers at least partially or completely on the main body 1 along the first direction and towards one side of the workpiece to be wound, then the range of the connection transition position between the wire arranging member 2 and the main body 1 is relatively large, resulting in easy bouncing and damage when the winding slides between the main body 1 and the wire arranging member 2.

[0082] For this reason, as Figure 6 - Figure 7 shown, the main body 1 is provided with a mounting through hole 13, and the protruding part 21 passes through the mounting through hole 13.

[0083] In this way, the protruding part 21 passes through the mounting through hole 13 inside the main body 1, that is, at least part of the protruding part 21 is hidden inside the main body 1, reducing the part of the wire arranging member 2 exposed outside the main body 1, so that the transition position between the wire arranging member 2 and the main body 1 is only limited to at least one side of the protruding part 21 along the second direction. Since the range of the transition position between the wire arranging member 2 and the main body 1 is significantly reduced, the friction between the winding and the transition position can be effectively reduced.

[0084] Among them, the number of the protruding parts 21 is multiple, and the multiple protruding parts 21 can be distributed on the main body 1 according to a certain rule. For example, the number of the protruding parts 21 is two, and the two protruding parts 21 are arranged along the third direction.

[0085] In one embodiment, as Figure 7 shown, the wire arranging member 2 further includes a connecting part 22, and the connecting part 22 is arranged between the two protruding parts 21. The connecting part 22 is used to realize the intermediate connection between the two protruding parts 21 to form an integral structure. At this time, the whole wire arranging member 2 is similar to a U-shaped structure.

[0086] In one embodiment, as Figure 7 - Figure 8 shown, the winding die head assembly 300 further includes a connecting member 3, and the connecting member 3 passes through the wire arranging member 2 and the main body 1 along the first direction.

[0087] Among them, the connecting member 3 can be a bolt or the like. The connecting part 22 of the wire arranging member 2 is provided with a first connecting hole, and the main body 1 is correspondingly provided with a second connecting hole for the first connecting part 22. The connecting member 3 passes through the first connecting hole and the second connecting hole to realize the installation between the main body 1 and the wire arranging member 2. Of course, the connecting member 3 can also be a connecting pin or a connecting rod, and the wire arranging member 2 and the main body 1 can slide along the connecting member 3. The connecting member 3 plays a guiding role and can adjust the relative position between the main body 1 and the wire arranging member 2.

[0088] In one embodiment, as Figure 7 - Figure 8 shown, the wire winding die head assembly 300 further includes an elastic member 4. The elastic member 4 is sleeved outside the connecting member 3 and is disposed between the wire arranging member 2 and the main body 1.

[0089] Among them, the elastic member 4 may be a spring. The elastic member 4 can provide a certain elastic force between the main body 1 and the wire arranging member 2, playing the roles of elasticity and buffering. In this way, the position of the main body 1 is not absolutely fixed. When the wire winding contacts the protruding portions 21 of the main body 1 and the wire arranging member 2, the main body 1 and the wire arranging member 2 can be movably adjusted to a certain extent in the first direction, avoiding the situation of the wire winding being too tight or too loose.
