[0023] Figure 2 A schematic diagram of a magnetic levitation ground module propulsion coil paint dipping tooling (excluding a pressure plate) according to an embodiment of the present invention is shown.

[0024] like Figure 1 and 2As shown, an embodiment of the present invention provides a maglev ground module propulsion coil dipping tooling, wherein the dipping tooling includes a tooling skeleton 21, a tooling bottom plate 22, a tooling pressure plate 23, a flange connection unit, a core unit, a push-pull mechanism 29, a pressure head 210 and a pressure block 211, the tooling skeleton 21 is arranged on the tooling bottom plate 22, the propulsion coil to be dipped in paint is arranged on the tooling skeleton 21 and is located between the tooling bottom plate 22 and the tooling pressure plate 23, the flange connection unit and the core unit cooperate with each other to The left contact seat insert and the right contact seat insert (high-voltage contact seat insert) of the propulsion coil to be dipped in paint are fixed, the pressure block 211 is arranged on the outer ring of the propulsion coil to be dipped in paint between the left contact seat insert and the right contact seat insert, the pressure head 210 is arranged on the outer ring of the propulsion coil to be dipped in paint except the pressure block 21, the push-pull mechanism 29 is used to apply pressure to the pressure head 210 to shape the overall external dimensions of the propulsion coil to be dipped in paint, and the pressure block 211 is used to shape the local external dimensions of the propulsion coil to be dipped in paint.

[0025] The propulsion coil to be dipped in paint can be a propulsion coil half-lapped with mica tape or a propulsion coil half-lapped with mica tape and polytetrafluoroethylene tape (for example, half-lapped with mica tape first, and then half-lapped with polytetrafluoroethylene tape on the outermost layer). The tooling frame is used to shape the propulsion coil to be dipped in paint.

[0026] Through the above technical scheme, the thickness dimension of the propulsion coil to be dipped in paint can be shaped through the interaction between the tooling pressure plate and the tooling bottom plate, the contact seat insert of the propulsion coil to be dipped in paint can be fixed by the flange connection unit and the core unit, and the overall external dimension of the propulsion coil to be dipped in paint can be shaped by the pressing block and the pressure head, and then the propulsion coil to be dipped in paint can be placed in the paint dipping container together with the paint dipping tooling, and the paint dipping operation can be performed, and the mold can be removed after the paint dipping is solidified to obtain the propulsion coil after dipping in paint. Therefore, the paint dipping tooling can not only shape and control the external dimension of the propulsion coil, but also complete the paint dipping of the propulsion coil, ensuring sufficient insulation strength and mechanical strength of the propulsion coil.

[0027] For example, there can be multiple pressing blocks, which are arranged around the outer circle of the push coil to be dipped in paint, and the number of the push-pull mechanisms is the same as the number of the pressing blocks.

[0028] According to one embodiment of the present invention, the painting tool further includes tool legs 212 disposed at the lower portion of the tool base plate 22 .

[0029] Thereby, the tool base plate of the dipping tool can be raised to make it easier to operate.

[0030] According to an embodiment of the present invention, the shaping tool further includes a connecting piece, through which the gap between the tool pressing plate 23 and the tool bottom plate 22 is changed.

[0031] Therefore, the gap between the tooling pressure plate and the tooling bottom plate can be adjusted more accurately through the connecting piece, so as to better realize the shaping (stereotyping) of the thickness direction dimension of the paint-impregnated push coil.

[0032] According to an embodiment of the present invention, the connecting member is a bolt.

[0033] Those skilled in the art should understand that the above-mentioned bolts are merely exemplary and are not intended to limit the present invention.

[0034] According to an embodiment of the present invention, the flange connection unit includes a left connection plate 24 , a right connection plate 25 and a connection plate pull plate 26 , and the left connection plate 24 and the right connection plate 25 are connected by the connection plate pull plate 26 .

[0035] That is, the connecting plate pull plate plays a role in strengthening the left connecting plate and the right connecting plate.

[0036] According to one embodiment of the present invention, the core mold unit includes an outer mold core 27 and an inner mold core 28, the left connecting plate 24 cooperates with the outer mold core 27 and the inner mold core 28 to fix the left contact seat insert, and the right connecting plate 25 cooperates with the outer mold core 27 and the inner mold core 28 to fix the right contact seat insert.

[0037] The number of core units can be multiple. Figure 1 For example, there may be two core units, one corresponding to the left connecting plate and the other corresponding to the right connecting plate.

[0038] For example, the inner mold core directly connected to the left contact seat insert passes through the left connecting plate and is connected to the outer mold core to fix the left contact seat insert, and the inner mold core directly connected to the right contact seat insert passes through the right connecting plate and is connected to the outer mold core to fix the right contact seat insert.

[0039] This prevents the epoxy varnish from entering the contact insert during the varnishing process.

[0040] According to one embodiment of the present invention, the paint dipping tool further comprises a metal strip, which is arranged between the pressure head 210 and the outer ring of the propulsion coil to be painted.

[0041] In this way, the pressure head can be guaranteed to be uniform.

[0042] According to an embodiment of the present invention, the metal bar is a stainless steel bar.

[0043] According to an embodiment of the present invention, the surface of the dipping tool is coated with a release agent, and the pores of the dipping tool are filled with the release agent.

[0044] By applying a release agent on the surface, the coil can be demoulded quickly and reliably. By filling the pores with a release agent, the tooling can be easily disassembled after the dip coating is completed.

[0045] According to an embodiment of the present invention, the pressing head 210 is a circular pressing head, and the square pressing block 211 is a square pressing block.

[0046] The following describes a magnetic levitation ground module propulsion coil painting tooling according to the present invention with reference to examples.

[0047] When performing a paint dipping operation using the paint dipping tool of the present invention, the following sequence can be followed:

[0048] 1) Coat a release agent on the surface of the propulsion coil dipping tooling, then sleeve the propulsion coil to be dipped in paint on the tooling frame installed on the dipping tooling, and install the high-voltage contact seat insert connected to the propulsion coil to be dipped in paint on the flange connection plate through the inner and outer mold cores to achieve position positioning and shaping between the high-voltage contact seat insert and the propulsion coil to be dipped in paint;

[0049] 2) After the thickness of the paint-impregnated advancing coil is pressed to a predetermined thickness by a tooling pressing plate, the push-pull mechanism around the outer circle of the paint-impregnated advancing coil is pushed to a position about 5 mm away from the outside of the paint-impregnated advancing coil, and then a 0.5 mm thick stainless steel bar is inserted between the pressure head and the outside of the paint-impregnated advancing coil to ensure that the pressure head exerts a uniform force, and then the push-pull mechanisms are pressed to the predetermined position one by one to achieve the shaping of the outer dimensions of the coil;

[0050] 3) Use a release agent to block the bolt holes, pin holes and other holes on the tooling to facilitate the disassembly of the tooling after the dipping is completed, and then put the propulsion coil dipping tooling together with the propulsion coil to be dipped into the dipping tank, and complete the dipping of the propulsion coil according to the dipping process;

[0051] 4) After the paint is cured, the mold is removed to complete the paint process for the propulsion coil.

[0052] Therefore, the paint dipping tooling of the present invention can not only shape and control the external dimensions of the propulsion coil, but also complete the paint dipping of the propulsion coil, thereby ensuring sufficient insulation strength of the propulsion coil.

[0053] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0054] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0055] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
