Description

Technical Field

[0001] This utility model relates to the field of winding mechanisms, and in particular to a protective mold structure for a high-side iron core. Background Technology

[0002] The protective plate is used to guide the enameled wire during the winding process of the stator, thereby avoiding wear of the enameled wire. In the existing winding mechanism, there is a type of iron core whose side height is much higher than the wire turn. In the actual winding process, there is an occasional problem of wire snagging, that is, the gap between the side and the protective plate is large. Therefore, how to improve it is the key to the design. Utility Model Content

[0003] The main purpose of this utility model is to propose a mold protection structure for a high-side iron core, which aims to guide the high-side structure, thereby avoiding the problem of snagging and realizing the processing applicability of non-standard products.

[0004] To achieve the above objectives, this utility model proposes a protective mold structure for a high-side iron core, comprising:

[0005] A base, wherein the base is provided with a horizontally sliding intermediate mold;

[0006] Side plates, which are provided on the left and right sides of the base;

[0007] The protective mold is sway-mounted at the rear of the protective mold on the base. The protective mold has upper and lower sides of the middle mold and is provided between the two side plates.

[0008] The protective mold is provided with an elastic element to drive the guide surfaces of the two protective molds to approach each other;

[0009] When the middle mold slides axially, it can drive the guide surfaces of the protective mold to switch between positions that are close to each other or positions that are far apart from each other.

[0010] In practical design, the front wall of the intermediate mold is used to fit against the end wall of the wire turn; the side plate is used to extend between two wire turns; the conductor surface of the protective mold is used to fit against or be close to the upper and lower ends of the wire turn.

[0011] This achieves guidance during winding. Furthermore, because different numbers and positions (winding length and position) of coils are different during winding, the axial sliding of the middle mold drives the spacing between the conductor surfaces of the two protective molds, thereby adjusting the swing angle of the protective molds. This reduces the problem of wire snagging when winding the high-side iron core. Attached Figure Description

[0031] The technical solutions of the embodiments of this utility model 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 utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0032] It should be noted that if any directional indication (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.) is involved in the embodiments of this utility model, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0033] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0034] like Figures 1 to 9 As shown, a protective mold 4 structure with a high-side iron core includes:

[0035] Base 1, wherein the base 1 is provided with a horizontally sliding middle mold 2;

[0036] Side plates 3 are provided on the left and right sides of the base 1;

[0037] The protective mold 4 is mounted on the base 1 with its rear part swinging. The protective mold 4 has upper and lower sides of the middle mold 2 and is located between the two side plates 3.

[0038] The protective mold 4 is provided with an elastic element 5 to drive the guide surfaces of the two protective molds 4 to approach each other;

[0039] When the middle mold 2 slides axially, it can drive the guide surfaces of the protective mold 4 to switch between positions that are close to each other or positions that are far apart from each other.

[0040] In the actual design, the front wall of the middle mold 2 is used to fit against the end wall of the wire turn; the side plate 3 is used to extend between the two wire turns; the conductor surface of the protective mold 4 is used to fit against or be close to the upper and lower ends of the wire turn.

[0041] This achieves guidance during winding. Furthermore, because different numbers and positions (length and position of the coils) of wire are different during winding, the axial sliding of the middle mold 2 drives the spacing between the conductor surfaces of the two protective molds 4, thereby adjusting the swing angle of the protective molds 4. This reduces the problem of wire snagging when winding the high-side iron core.

[0042] Specifically, the protective mold 4 extends with a curved arm 40, and the guide surface is provided with a position corresponding to the end of the curved arm 40.

[0043] The conductor surface is used to guide the upper and lower edges of the iron core, that is, to avoid interference between the various movements by using a predetermined shape.

[0044] In this embodiment of the utility model, the end of the curved arm 40 is a solid wall 41 or is provided with a through groove 42. For example, when the high side of the iron core is provided with a hook needle, the hook needle can be positioned to avoid being misaligned, as in the second embodiment.

[0045] Specifically, the side plates 3 are fixed to both sides of the middle mold 2, for example, in the second embodiment.

[0046] In this embodiment of the utility model, the two side plates 3 are an integral structure. The two side plates 3 are slidably installed on the base 1 and can slide back and forth in the axial direction. A second top spring 6 is provided between the base 1 and the integral structure to drive the integral structure to move forward.

[0047] Specifically, the inner side of the curved arm 40 is provided with a first inclined surface 71, and the middle mold 2 extends to both sides with a second inclined surface 72 that cooperates with the first inclined surface 71. That is, the relative position of the guide surface of the curved arm 40 is adjusted by the abutment of the first inclined surface 71 and the second inclined surface 72.

[0048] In this embodiment of the utility model, the base 1 is provided with a swing shaft 8, and the rear end of the protective mold 4 is oscillating through the swing shaft 8.

[0049] Specifically, the swing shaft 8 is provided with the elastic element 5, which is a torsion spring. The torsion spring is used to drive the guide wire surface of the swing shaft 8 to move in the axial direction.

[0050] In this embodiment of the utility model, the upper and lower walls of the middle mold 2 are provided with elastic pads 81, thereby reducing the rigid collision between the middle mold 2 and the protective mold 4.

[0051] Specifically, the front wall of the intermediate mold 2 is recessed with a contour surface 20, which can cover the front wall of the wire coil.

[0052] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
