At this time, the limiting part limits the first coil and the second coil along the first direction, so that the first coil and the second coil are coplanar along the first direction; in addition, since the first end of the first inner mold along the third direction is flush with the third end of the second inner mold along the third direction, when the first coil is sleeved on the first inner mold and the second coil is sleeved on the second inner mold, the first end of the first inner mold is used to limit one end of the first coil along the third direction, and the third end of the second inner mold is used to limit one end of the second coil along the third direction, it can be ensured that the end of the first coil corresponding to the first end of the first inner mold and the end of the second coil corresponding to the third end of the second inner mold are flush; and since the two sides of the first inner mold along the second direction are used to limit the two sides corresponding to the first coil respectively, the two sides of the second inner mold along the second direction are used to respectively The two sides corresponding to the second coil are limited, that is, the width of the inner circle of the first coil along the second direction is equal to the width of the first inner mold along the second direction or has a gap that meets the tolerance requirements, and the width of the inner circle of the second coil along the second direction is equal to the width of the second inner mold along the second direction or has a gap that meets the tolerance requirements, so that when the first coil is sleeved on the first inner mold and the second coil is sleeved on the second inner mold, the first coil can be clamped on the first inner mold to determine the position of the first coil along the second direction, and the second coil can be clamped on the second inner mold to determine the position of the second coil along the second direction, that is, the width of the first inner mold and the second inner mold along the second direction determines the positions of the first coil and the second limiter along the second direction, which is conducive to making the distance from the center line of the first coil to the center line between the first inner mold and the second inner mold equal to the distance from the center line of the second coil to the center line between the first inner mold and the second inner mold, that is, it is conducive to ensuring that the center distances of the first coil and the second coil to the desired positions are equal.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The core of the present invention is to provide a magnetic levitation pole coil welding tool, which can avoid the misalignment of the two coils in the magnetic levitation pole when welding. Another core of the present invention is to provide a magnetic levitation pole coil welding device including the magnetic levitation pole coil welding tool, which can avoid the misalignment of the two coils in the magnetic levitation pole when welding.

[0033] Please refer to Figure 1-Figure 3 The embodiment of the present invention provides a magnetic suspension pole coil welding tool, comprising a mounting seat 1, a first inner mold 2, a second inner mold 3 and a support seat 4, wherein the mounting seat 1 is provided with a limiting portion, the limiting portion is used to limit the first coil 6 and the second coil 7 along the first direction, so that the first coil 6 and the second coil 7 are coplanar along the first direction; the first inner mold 2 and the second inner mold 3 are arranged at intervals on the mounting seat 1 along the second direction, the first end of the first inner mold 2 along the third direction and the third end of the second inner mold 3 along the third direction are flush, the first inner mold 2 is used to sleeve the first coil 6, the second inner mold 3 is used to sleeve the second coil 7, the first end is used to limit one end of the first coil 6, the third end is used to limit one end of the second coil 7, the first inner mold 2 along the second direction The two sides are used to limit the two sides corresponding to the first coil 6 respectively, and the second inner mold 3 along the second direction The two sides are used to limit the two sides corresponding to the second coil 7 respectively; wherein the first direction, the second direction and the third direction are perpendicular to each other; the support seat 4 is arranged on the mounting seat 1, and the support seat 4 is provided with a supporting surface 41 for placing the connecting wire of the first coil 6 and the second coil 7.

[0034] When it is necessary to weld the first coil 6 and the second coil 7, the first coil 6 is sleeved on the outer periphery of the first inner mold 2, and the second coil 7 is sleeved on the outer periphery of the second inner mold 3. At this time, the limiting part limits the first coil 6 and the second coil 7 along the first direction, so that the first coil 6 and the second coil 7 are coplanar along the first direction; in addition, since the first end of the first inner mold 2 along the third direction is flush with the third end of the second inner mold 3 along the third direction, when the first coil 6 is sleeved on the first inner mold 2 and the second coil 7 is sleeved on the second inner mold 3, the first end of the first inner mold 2 is used to limit one end of the first coil 6 along the third direction, and the third end of the second inner mold 3 is used to limit one end of the second coil 7 along the third direction, which can ensure that the end of the first coil 6 corresponding to the first end of the first inner mold 2 and the end of the second coil 7 corresponding to the third end of the second inner mold 3 are flush; in addition, since the two sides of the first inner mold 2 along the second direction are used to limit the two sides corresponding to the first coil 6 respectively, and the two sides of the second inner mold 3 along the second direction are used to limit the two sides corresponding to the second coil 7 respectively , that is, the width of the inner circle of the first coil 6 along the second direction is equal to the width of the first inner mold 2 along the second direction or has a gap that meets the tolerance requirements, and the width of the inner circle of the second coil 7 along the second direction is equal to the width of the second inner mold 3 along the second direction or has a gap that meets the tolerance requirements, so that when the first coil 6 is sleeved on the first inner mold 2 and the second coil 7 is sleeved on the second inner mold 3, the first coil 6 can be clamped on the first inner mold 2, so that the position of the first coil 6 along the second direction is determined, and the second coil 7 can be clamped on the second inner mold 3, so that the position of the second coil 7 along the second direction is determined, that is, the width of the first inner mold 2 and the second inner mold 3 along the second direction determines the position of the first coil 6 and the second limit respectively along the second direction, which is conducive to making the distance from the center line of the first coil 6 to the center line between the first inner mold 2 and the second inner mold 3 equal to the distance from the center line of the second coil 7 to the center line between the first inner mold 2 and the second inner mold 3, that is, it is conducive to ensuring that the center distances of the first coil 6 and the second coil 7 to the desired positions are equal.

[0035] It can be seen that the embodiments of the present invention respectively utilize the limiting portion of the mounting seat 1, the relative position of the first inner mold 2 and the second inner mold 3, and the respective structural dimensions of the first inner mold 2 and the second inner mold 3 to limit the position of the first coil 6 and the second coil 7, so that the first coil 6 and the second coil 7 are limited along the first direction, the second direction and the third direction respectively, and the relative position of the first coil 6 and the second coil 7 is kept unchanged. After the first coil 6 and the second coil 7 are positioned, the connecting wires of the first coil 6 and the second coil 7 are respectively placed on the supporting surface 41 of the supporting seat 4, and the connecting wires of the first coil 6 and the second coil 7 are welded using the welding joint of the magnetic levitation pole coil welding equipment. During the welding process, the first coil 6 and the second coil 7 are limited by the limiting portion, the first inner mold 2 and the second inner mold 3, so that the relative position of the first coil 6 and the second coil 7 remains unchanged. Therefore, the misalignment of the first coil 6 and the second coil 7 during welding can be avoided.

[0036] In some embodiments, the width of the first inner mold 2 along the second direction is equal to the width of the second inner mold 3 along the second direction. In this case, the inner turns of the first coil 6 and the second coil 7 have the same size along the second direction.

[0037] In order to facilitate the limiting of the first coil 6 and the second coil 7 along the first direction, in some embodiments, the mounting base 1 includes a first flat plate 11, and the first inner mold 2 and the second inner mold 3 are respectively connected to the first flat plate 11 on one side along the first direction, and the limiting portion is a fitting surface on the first flat plate 11 for fitting with the first coil 6 and the second coil 7.

[0038] That is to say, in this embodiment, by setting the first flat plate 11, the first inner mold 2 and the second inner mold 3 are respectively installed on one side (i.e., the installation surface) of the first flat plate 11. In this way, when the first coil 6 is sleeved on the outer periphery of the first inner mold 2 and the second coil 7 is sleeved on the outer periphery of the second inner mold 3, the first coil 6 and the second coil 7 can be respectively attached to the installation surface of the first flat plate 11, so that the installation surface of the first flat plate 11 can be used to limit the first coil 6 and the second coil 7 along the first direction. At this time, the attachment surface on the installation surface of the first flat plate 11 used to attach the first coil 6 and the second coil 7 respectively is the limiting part. This structure is simple, and it is convenient to limit the first coil 6 and the second coil 7 along the first direction, and at the same time, it is convenient to install the first inner mold 2 and the second inner mold 3.

[0039] In some embodiments, the mounting base 1 is provided with an outer mold 5, which is arranged between the first inner mold 2 and the second inner mold 3. The distance between the outer mold 5 and the first inner mold 2 is equal to the distance between the outer mold 5 and the second inner mold 3. The two sides of the outer mold 5 along the second direction are used to limit the corresponding sides of the first coil 6 and the second coil 7 respectively.

[0040] That is to say, the first inner mold 2 and the second inner mold 3 are symmetrically arranged with respect to the outer mold 5, which helps to ensure that the center distances of the first coil 6 and the second coil 7 to the center line of the outer mold 5 along the second direction are equal. Moreover, the two sides of the outer mold 5 along the second direction are used to limit the corresponding sides of the first coil 6 and the second coil 7 respectively, that is, the distance between the outer mold 5 and the first inner mold 2 is equal to the single-side width of the first coil 6 along the second direction or has a fitting gap that meets the tolerance requirements, and the distance between the outer mold 5 and the second inner mold 3 is equal to the single-side width of the second coil 7 along the second direction or has a fitting gap that meets the tolerance requirements. In this way, when installing the first coil 6 and the second coil 7, the first coil 6 is directly sleeved on the outer periphery of the first inner mold 2, and the second coil 7 is sleeved on the outer periphery of the second inner mold 3. At this time, the part of the first coil 6 located between the outer mold 5 and the first inner mold 2 is just stuck between the outer mold 5 and the first inner mold 2, and the part of the second coil 7 located between the outer mold 5 and the second inner mold 3 is just stuck between the outer mold 5 and the second inner mold 3, which is conducive to facilitating the rapid installation and positioning of the first coil 6 and the second coil 7, and is conducive to keeping the position of the first coil 6 and the second coil 7 unchanged, further preventing the first coil 6 and the second coil 7 from being misaligned during the welding process.

[0041] Furthermore, in some embodiments, the center line of the width of the outer mold 5 along the second direction is colinear with the center line of the width of the first plate 11 along the second direction. This facilitates determining the position of the outer mold 5 by fixing the first plate 11, and further facilitates determining that the center distances of the first coil 6 and the second coil 7 to the desired positions are equal.

[0042] In addition, in order to facilitate the welding of the connecting wires of the first coil 6 and the second coil 7, in some embodiments, the support seat 4 is arranged on the side of the first flat plate 11 facing the first inner mold 2 and the second inner mold 3, and the first flat plate 11 is provided with a through hole 111 penetrating through its wall thickness, and the through hole 111 is used to allow the welding joint of the connecting wires of the first coil 6 and the second coil 7 to pass through.

[0043] That is to say, in this embodiment, a through hole 111 penetrating the wall thickness of the first plate 11 is provided, so that the welding joint enters the mounting surface side of the first plate 11 through the through hole 111 from the non-mounting surface of the first plate 11, so as to facilitate the welding of the connecting wire located on the supporting surface 41 of the support seat 4 and facilitate the welding operation.

[0044] In some embodiments, the welded joint is an ultrasonic welded joint.

[0045] Further, in some embodiments, the through hole 111 is a U-shaped hole, and the opening of the U-shaped hole is located at a side wall of the first plate 11 along the second direction.

[0046] That is to say, in this embodiment, the through hole 111 extends to one side of the first plate 11 along the second direction, and penetrates the side wall of the first plate 11 along one side of the second direction to form a U-shaped hole with an opening, which facilitates the welding joint to enter the through hole 111 and facilitates operation.

[0047] In addition, in some embodiments, the second end of the first inner mold 2 along the third direction is flush with the fourth end of the second inner mold 3 along the third direction, the second end is used to limit one end of the first coil 6, and the fourth end is used to limit one end of the second coil 7.

[0048] That is to say, in this embodiment, the two ends (i.e., the first end and the second end) of the first inner mold 2 along the third direction are used to limit the corresponding two ends of the first coil 6, that is, the length of the first inner mold 2 along the third direction is equal to the length of the inner circle of the first coil 6 along the third direction or has a matching gap that meets the tolerance requirements, so that when the first coil 6 is sleeved on the first inner mold 2, the two ends of the first inner mold 2 along the third direction determine the positions of the two ends of the first coil 6 along the third direction, and the position of the first coil 6 along the third direction remains unchanged. Similarly, in this embodiment, the two ends (i.e., the third end and the fourth end) of the second inner mold 3 along the third direction are used to limit the corresponding two ends of the second coil 7, that is, the length of the second inner mold 3 along the third direction is equal to the length of the inner circle of the second coil 7 along the third direction or has a matching gap that meets the tolerance requirements, so that when the second coil 7 is sleeved on the second inner mold 3, the two ends of the second inner mold 3 along the third direction determine the positions of the two ends of the second coil 7 along the third direction, and the position of the second coil 7 along the third direction remains unchanged.

[0049] In some embodiments, the third direction is a vertical direction. It is understandable that when the third direction is a vertical direction, the first end of the first inner mold 2 is set at the top and the second end belongs to the bottom. At this time, after the first coil 6 is sleeved on the first inner mold 2, it is beneficial to the first end to realize the limitation of the first coil 6 along the third direction. Since the first coil 6 is in a suspended state, it is beneficial to gravity to maintain the position of the first coil 6 at both ends along the third direction. Similarly, when the third direction is a vertical direction, the third end of the second inner mold 3 is set at the top and the fourth end belongs to the bottom. At this time, after the second coil 7 is sleeved on the second inner mold 3, it is beneficial to the third end to realize the limitation of the second coil 7 along the third direction. Since the second coil 7 is in a suspended state, it is beneficial to gravity to maintain the position of the second coil 7 at both ends along the third direction. Of course, it is better to use the first end and the second end to limit the two ends of the first coil 6 along the third direction respectively, and it is better to use the third end and the fourth end to limit the two ends of the second coil 7 along the third direction respectively, which is beneficial to ensure the stability of the positions of the first coil 6 and the second coil 7.

[0050] Further, in some embodiments, the support surface 41 of the support seat 4, the lower inner wall of the through hole 111 along the third direction, the second end and the fourth end are coplanar. That is, the support surface 41 of the support seat 4, the lower inner wall of the through hole 111 along the third direction, the second end and the fourth end are flush along the third direction, so as to ensure that the position of the connecting wire of the first coil 6 and the second coil 7 after welding is flush with the inner circle of the first coil 6 and the second coil 7.

[0051] For the convenience of description, the connecting wire of the first coil 6 is called the first connecting wire 61, and the connecting wire of the second coil is called the second connecting wire 71. In some embodiments, after the first coil 6 is sleeved on the first inner mold 2 and the second coil 7 is sleeved on the second inner mold 3, the lengths of the first connecting wire 61 and the second connecting wire 71 are adjusted respectively, so that the end of the first connecting wire 61 is aligned with the side of the support surface 41 away from the first coil 6, and the end of the second connecting wire 71 is aligned with the side of the support surface 41 away from the second coil 7, which is conducive to ensuring that the first connecting wire 61 and the second connecting wire 71 have sufficient overlapping length, increase the welding length, and ensure the reliability of the connection between the first coil 6 and the second coil 7. Of course, in other embodiments, the ends of the first connecting wire 61 and the second connecting wire 71 can also be butt-welded.

[0052] Furthermore, in order to facilitate the fixing of the magnetic suspension pole coil welding tool, in some embodiments, the mounting base 1 further includes a second plate 12 vertically connected to the first plate 11, and the second plate 12 is provided with a mounting hole 121. That is, when the magnetic suspension pole coil welding tool is fixed to the magnetic suspension pole coil welding equipment, the second plate 12 can be fixed to the magnetic suspension pole coil welding equipment by fasteners penetrating the mounting hole 121, thereby realizing the overall installation and fixation of the magnetic suspension pole coil welding tool, which is convenient for ensuring that the first plate 11 has a suitable position.

[0053] In some embodiments, the first plate 11 and the second plate 12 form an L-shaped structure. This structure is simple.

[0054] In addition to the above-mentioned magnetic suspension pole coil welding tool, the present invention also provides a magnetic suspension pole coil welding device including the magnetic suspension pole coil welding tool disclosed in the above-mentioned embodiment. The structures of other parts of the magnetic suspension pole coil welding device can be referred to in the related art, which will not be described in detail herein. For example, in some embodiments, the magnetic suspension pole coil welding device is an ultrasonic welding machine.

[0055] The key point of this embodiment is that the magnetic levitation pole coil welding equipment includes the magnetic levitation pole coil welding tool disclosed in any one of the above embodiments, and at least has the beneficial effects of the above magnetic levitation pole coil welding tool.

[0056] It should also be noted that, in this specification, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0057] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
