Description

Technical Field

[0001] This invention belongs to the technical field of reactor equipment, specifically relating to a vertical fixing mechanism for reactor core columns and a method for epoxy casting after fixing. Background Technology

[0002] In the prior art, the working principle of a reactor is to wind a coil made of wire around the outside of a stacked iron core. After the coil conducts electricity, it generates a self-induced electromotive force under the action of the internal iron core. The self-induced electromotive force will impede the change of current, thereby generating inductive reactance.

[0003] In the prior art, the main components of a reactor include the reactor shell and the internal reactor core. The reactor shell is usually cast by a mold, and the inside is equipped with wound coils; while the reactor core is formed by stacking reactor core cakes and air gap plates at intervals.

[0004] In existing technologies, reactor core columns require maintaining the verticality of the core cake during stacking during manufacturing. Therefore, vertical molds are often used to fabricate core columns, where the core cake and air gap plate are simply placed inside the mold. However, a problem arises because epoxy resin is usually applied between the air gap plate and the core cake to bond them together. But when the air gap plate and core cake are compressed, if too much epoxy resin is applied, it will adhere directly to the outer vertical mold. Once the resin dries, the mold and core column will stick together, making them very difficult to separate, increasing the difficulty and cost of the process.

[0005] In addition, in the existing technology, after the core column is completed, it needs to be installed inside the reactor shell, and epoxy resin needs to be poured into the casting gap. The vertical fixing of the reactor core column and the pouring of epoxy resin in the existing technology are carried out in two steps and require two sets of equipment, which will seriously affect the work quality and efficiency.

[0006] To solve the above technical problems, it is necessary to develop a vertical fixing mechanism for reactor core columns and a method for epoxy casting after fixing. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing technologies by providing a vertical fixing mechanism for reactor core columns and a method for epoxy casting after fixing. The technical solution is as follows:

[0008] A reactor core column vertical fixing mechanism includes a fixed base on which an insulating plate is placed. The fixed base also has several sets of vertically extending positioning columns. Each set of positioning columns has several arc-shaped positioning plates. The positioning plates have positioning holes corresponding to the positions of the positioning columns. The positioning columns pass through the positioning holes so that the positioning plates are stacked on the positioning columns. Each positioning column has a detachable pressure block installed at its upper end. The pressure block presses the stacked positioning plates firmly onto the positioning column.

[0009] The positioning plate forms a circular outline area, which is set as the placement area for the reactor core cake. The core cake is stacked with the air gap plate in the placement area to form the reactor core column. The inner diameter of the placement area is adapted to the outer diameter of the reactor core column, and the reactor core column is perpendicular to the placement area.

[0010] A pressing mechanism is also provided directly above the placement area. The main shaft of the pressing mechanism extends downward and a pressure plate is installed at the shaft end. The size of the pressure plate is the same as the size of the reactor core column. After the reactor core columns are stacked in the placement area, the pressing mechanism above drives the pressure plate to press against the upper end of the reactor core column to achieve fixation.

[0011] Furthermore, the fixed base has four sets of positioning posts, each set having two positioning posts; and each positioning plate has two positioning holes, with a vertical gap between the positioning plates on adjacent sets of positioning posts, and the size of the positioning plates on each set of positioning posts is consistent.

[0012] Furthermore, an infrared emitter is also provided on the side wall of the pressure plate. The infrared emitter is located directly above the vertical gap formed by the adjacent positioning plates. The infrared emitter emits light vertically downward and is attached to the side wall of the pressure plate. The light from the infrared emitter shines vertically downward onto the positioning plate below without obstruction.

[0013] Furthermore, it also includes a reactor housing, the inside of which is wound with coils, and the reactor housing is also provided with heat dissipation holes, and there are a total of four heat dissipation holes, and the heat dissipation holes are set in an arc-shaped waist-shaped hole structure. The positions of the four heat dissipation holes are consistent with the positions of four sets of positioning posts, and the two positioning posts in each set of positioning posts are located at both ends of each heat dissipation hole.

[0014] After the positioning plate on the positioning column is removed, the reactor housing is fitted onto the outside of the reactor core column and positioned accordingly by the positioning column. After the reactor housing is installed, a casting gap is left between the inner wall of the reactor housing and the reactor core column.

[0015] Furthermore, the positioning post is mounted on the fixed base in a vertically lifting structure; the fixed base is provided with a through hole corresponding to the position of the positioning post, and the positioning post extends downward through the through hole; and the side of the fixed base is also equipped with a lifting mechanism corresponding to the position of the positioning post, the lifting mechanism is connected to the lower end of the positioning post through a bent connecting rod, and the positioning post can be moved downward accordingly through the lifting mechanism.

[0016] Furthermore, the upper end of the positioning post is provided with a threaded structure, and the pressure block is fixed to the positioning post in a detachable and washable manner through the threaded structure.

[0017] Furthermore, there are four sets of infrared emitters on the pressure plate, and each set of infrared emitters corresponds to the vertical gap position below.

[0018] This invention also provides an epoxy casting method based on a reactor core column vertical fixing mechanism, specifically including the following steps:

[0019] Positioning plates are installed on the four sets of positioning columns. The positioning plates are locked by the pressure blocks at the upper end of the positioning plates. The four sets of positioning plates form a placement area. Reactor core cakes and air gap plates are stacked in the placement area at intervals. During the stacking process, epoxy glue is applied to the upper and lower edges of the air gap plates and the edges of the reactor core cakes to form a whole reactor core column. After the stacking is completed, the pressure plate is moved downward by the upper pressing mechanism. Before the pressure plate presses down on the reactor core column, the infrared emitter emits light to determine whether the reactor core column is vertical. If it is not vertical, the position of the core cake is manually adjusted to make the whole core column vertical.

[0020] The pressing mechanism drives the pressure plate to press down on the reactor core column, so that the reactor core cake and the air gap plate are pressed together and wait for the glue to dry. After the glue dries, the reactor core column is fixed and formed. Then, the positioning plate on each set of positioning columns is removed. After the positioning plate is removed, the pressing mechanism above simultaneously drives the pressure plate to move up to make room.

[0021] The reactor housing is fitted onto the outside of the reactor core column from above. The four sets of positioning posts cooperate with the four sets of heat dissipation holes on the reactor housing. The two posts in each set of positioning posts are inserted into the two ends of the same heat dissipation hole, thereby fixing the reactor housing to the outside of the reactor core column.

[0022] A casting gap is left between the reactor shell and the reactor core column. Epoxy resin is poured into this casting gap. After the epoxy resin solidifies, the reactor shell and the reactor core column are cast as one piece. Then, the positioning column is moved downward by the lifting mechanism, so that the positioning column is disengaged from the heat dissipation hole of the reactor shell. After the reactor shell is no longer restricted by the positioning column, the reactor shell and the internally cast reactor core column are removed.

[0023] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0024] 1) This invention can realize the vertical fixing of the reactor core column and the epoxy resin casting after vertical fixing, casting the reactor core column and the reactor shell into one piece, integrating vertical fixing and casting into an integrated structure, effectively improving work efficiency and product quality.

[0025] 2) This invention uses positioning columns to install positioning plates, which in turn position the reactor core cakes. The reactor core cakes and air gap plates are stacked at intervals to form reactor core columns. Vertical positioning is very convenient and quick. It is simple and convenient to simply install the reactor core cakes in the placement area.

[0026] 3) In this invention, epoxy adhesive is applied to the reactor core cake and the air gap plate and then pressed and bonded by a pressing device. The positioning plate is set in a split stack form. By disassembling the positioning plates one by one, the adhesion of epoxy adhesive to the positioning plates is reduced. The separation and disassembly of the positioning plates from the internal reactor core column is more convenient and will not be affected by epoxy adhesive.

[0027] 4) In this invention, after the positioning plate is disassembled, the reactor housing can be installed on the positioning post. The reactor housing is installed by cooperating with the positioning post through the heat dissipation holes provided on the reactor housing. The position of the reactor housing can be easily positioned and fixed, so that the epoxy resin casting work can be quickly realized. The structural design is very ingenious.

[0028] 5) In this invention, the positioning column is designed to be movable up and down. A casting gap is provided between the reactor shell and the reactor core column. Epoxy resin is cast through this casting gap. After the casting is completed, the positioning column is moved downward. After the positioning column is removed from the restriction of the positioning column, the entire reactor can be easily disassembled. Attached Figure Description

Detailed Implementation

[0039] The present invention will be further illustrated below with reference to specific embodiments. These embodiments are implemented based on the technical solutions of the present invention, and it should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0040] Example 1

[0041] like Figure 1 As shown, the reactor core column vertical fixing mechanism of this embodiment includes a fixed base 1, on which an insulating plate 19 is placed. The fixed base 1 of this embodiment is also provided with a number of vertically upward-extending positioning columns 3. Each group of positioning columns 3 is provided with a number of arc-shaped positioning plates 2. The positioning plates 2 of this embodiment are provided with positioning holes 4 corresponding to the positions of the positioning columns 3. The positioning columns 3 pass through the positioning holes 4 so that the positioning plates 2 are stacked on the positioning columns 3. The upper end of each positioning column 3 is provided with a detachable pressure block 5, which presses the stacked positioning plates 2 onto the positioning columns 3.

[0042] like Figure 2 As shown, the positioning plate 2 in this embodiment forms a circular outline area, which is set as the placement area 6 for the reactor core cake 7. The core cake is stacked with the air gap plate 8 in the placement area 6 to form the reactor core column. The inner diameter of the placement area 6 is adapted to the outer diameter of the reactor core column, and the reactor core column is perpendicular to the placement area 6.

[0043] like Figure 3As shown, a pressing mechanism 9 is also provided directly above the placement area 6 in this embodiment. The main shaft of the pressing mechanism 9 extends downward and a pressure plate 10 is installed at the shaft end. The size of the pressure plate 10 is the same as the size of the reactor core column. After the reactor core columns are stacked in the placement area 6, the pressing mechanism 9 above drives the pressure plate 10 to press against the upper end of the reactor core column to achieve fixation.

[0044] In this embodiment, the positioning pins 3 on the fixed base 1 are arranged in four groups, and each group is provided with two positioning pins 3; and each positioning plate 2 is provided with two positioning holes 4, and a vertical gap 11 is left between the positioning plates 2 on adjacent groups of positioning pins 3, and the size of the positioning plates 2 on each group of positioning pins 3 is consistent.

[0045] In this embodiment, an infrared emitter 12 is also provided on the side wall of the pressure plate 10. The infrared emitter 12 is located directly above the vertical gap 11 formed by the adjacent positioning plates 2. The infrared emitter 12 emits light vertically downward and is placed on the side wall of the pressure plate 10. The light from the infrared emitter 12 shines vertically downward onto the positioning plate 2 below without obstruction.

[0046] like Figure 8 and Figure 9 As shown, it also includes a reactor housing 13, inside which a coil 14 is wound, and the reactor housing 13 is also provided with heat dissipation holes 15. In this embodiment, there are four heat dissipation holes 15, and the heat dissipation holes 15 are set as arc-shaped waist-shaped hole structures. The positions of the four heat dissipation holes 15 are consistent with the positions of the four sets of positioning posts 3, and the two positioning posts 3 in each set of positioning posts 3 are located at both ends of each heat dissipation hole 15.

[0047] like Figure 4 and Figure 5 As shown, after the positioning plate 2 on the positioning column 3 is removed, the reactor housing 13 is fitted onto the outside of the reactor core column and positioned accordingly by the positioning column 3. After the reactor housing 13 is installed, a casting gap 19 is left between the inner wall of the reactor housing 13 and the reactor core column.

[0048] like Figure 6 and Figure 7 As shown, in this embodiment, the positioning post 3 is mounted on the fixed base 1 in a vertically lifting structure; the fixed base 1 in this embodiment is provided with a through hole 16 corresponding to the position of the positioning post 3, and the positioning post 3 extends downward through the through hole 16; and the side of the fixed base 1 in this embodiment is also equipped with a lifting mechanism 17 corresponding to the position of the positioning post 3. The lifting mechanism 17 in this embodiment is connected to the lower end of the positioning post 3 through a bent connecting rod 18, and the positioning post 3 can be moved downward accordingly by the lifting mechanism 17.

[0049] In this embodiment, the upper end of the positioning post 3 is provided with a threaded structure. The pressure block 5 in this embodiment is fixed to the positioning post 3 in a detachable and washable manner through the threaded structure. In this embodiment, there are four sets of infrared emitters 12 on the pressure plate 10, and the four sets of infrared emitters 12 correspond to the position of the vertical gap 11 below.

[0050] Example 2

[0051] In addition to the extrusion method of the technical solution in Embodiment 1, this invention also provides an epoxy casting method based on a vertical fixing mechanism for reactor core columns. The technical solution of this embodiment integrates the vertical fixing of the reactor core column and the epoxy casting after fixing. First, in this embodiment, positioning plates 2 are placed on the four sets of positioning columns 3. Each set of positioning columns 3 has two columns, and the positioning plates 2 have two positioning holes 4. The positioning plates 2 are stacked on the positioning columns 3. After stacking, they form an overall positioning area on the positioning columns 3. The shape and size of the positioning plates 2 on each set of positioning columns 3 are the same. After the positioning plates 2 on the four sets of positioning columns 3 are installed, a placement area 6 for placing the reactor core cake 7 is formed in the middle position. The size of the placement area 6 is consistent with the size of the reactor core cake 7. The size of the reactor core column formed by the reactor core cake 7 is also consistent. Therefore, the reactor core cake 7 and the air gap plate 8 can be directly stacked in the placement area 6.

[0052] In specific operation, positioning plates 2 are installed on the four sets of positioning columns 3 respectively. The positioning plates 2 are locked by the pressure blocks 5 at the upper end of the positioning plates 2. The four sets of positioning plates 2 form a placement area 6. Reactor core cakes 7 and air gap plates 8 are stacked at intervals in the placement area 6. The reactor core column is formed by stacking the reactor core cakes 7 and air gap plates 8 at intervals. The air gap plates 8 are usually made of breathable material, and the reactor core cakes 7 are usually made of silicon steel sheets. During the stacking process, the air gaps... Apply a ring of epoxy adhesive to the upper and lower edges of plate 8 and the edge of reactor core cake 7, and gradually stack them into a whole reactor core column. After stacking, pressure needs to be applied to glue the reactor core cake 7 and air gap plate 8 together. In this embodiment, the pressure plate 10 is controlled to move downward by the upper pressing mechanism 9. The pressure plate 10 is used to glue the reactor core cake 7 and air gap plate 8. Before pressing, the infrared emitter 12 is used to further detect whether the reactor core column is vertical.

[0053] The area formed by the four sets of positioning plates 2 in this device is a fixed area. The reactor core column formed after stacking should be vertical. However, just in case, an infrared emitter 12 that can emit light downwards is also set at the side wall of the pressure plate 10 in this embodiment. First, the size of the pressure plate 10 is consistent with the size of the reactor core column. In addition, the infrared emitter 12 is set to be close to the side wall of the pressure plate 10 and emits light vertically downwards, as shown in the figure. If the entire reactor core column is vertical, then the light at the four vertical gaps 11 can all shine vertically downwards onto the insulating plate 19. If the light does not reach the lower insulating plate 19, it means that the reactor core column is not vertical. The reactor core chip 7 that does not meet the vertical requirements can be found according to the position where the light is broken. The position of the reactor chip can be manually adjusted to make the light shine downwards, so as to achieve the verticality of the entire reactor core column.

[0054] In this embodiment, the four sets of positioning plates 2 form a vertical gap 11, and the infrared transmitter 12 can be installed on the pressure plate 10 directly above the vertical gap 11. The vertical position can be detected by the infrared transmitter 12 at this position.

[0055] When the reactor core column is vertical, the pressing mechanism 9 drives the pressure plate 10 to press the reactor core column, so that the reactor core cake 7 and the air gap plate 8 are correspondingly compacted. During this pressing process, the pressure value and other data of the pressing mechanism 9 are adjusted to prevent excessive pressing of the air gap plate 8 and the reactor core cake 7. After pressing, a certain time is waited for the adhesive to dry. After the adhesive dries, the air gap plate 8 and the reactor core cake 7 are fixed and formed into an integral reactor core column under the action of epoxy adhesive. During the pressing and drying process, the epoxy adhesive will adhere to the outer positioning plate 2 after being pressed. If the positioning plate 2 is an integral plate structure at this time, the reactor core column... The outer positioning plate 2 is difficult to separate due to the adhesion of epoxy adhesive. However, in this embodiment, since the positioning plate 2 itself is set in a stacked manner and is detachable, it is only necessary to first remove the upper pressure block 5, and then remove the epoxy adhesive stacked on the positioning column 3 one by one. The difficulty will be greatly reduced. This split structure can effectively reduce the disassembly work of the internal reactor core column, and it is very convenient to separate the reactor core column from the positioning plate 2. After all the outer positioning plates 2 are removed, the internal reactor core column is a whole structure. Then, the upper pressing mechanism 9 needs to simultaneously drive the pressure plate 10 to move upward to make room.

[0056] At this point, the reactor core is an integral column structure, which needs to be installed as a whole with the reactor housing 13, as shown in Figures 1 and 2. In the prior art, the reactor housing 13 needs to be equipped with a coil 14 inside, and then the reactor core is fitted inside the coil 14. The coil 14 generates inductive reactance when energized. In the prior art, the reactor core and the reactor housing 13 need to be cast together with epoxy resin to form an integral reactor. However, the reactor housing 13 in this embodiment is different from the prior art in that it is provided with four evenly spaced and identically sized heat dissipation holes 15. The design of the heat dissipation holes 15 in this embodiment is for the purpose of heat dissipation and also to cooperate with the positioning column 3 to provide a positional basis for subsequent casting work.

[0057] In this embodiment, after removing the positioning plate 2 from the positioning post 3, the reactor housing 13 can be installed from above. The position of the heat dissipation hole 15 is adapted to the position of the two positioning posts 3 in each group. The two positioning posts 3 in the same group are located at the two ends of the same heat dissipation hole 15. The heat dissipation hole 15 itself has an oblong structure with semi-circular structures on both sides, and its size is adapted to the positioning post 3. After the positioning post 3 is inserted into the heat dissipation hole 15, the reactor housing 13 is fixed accordingly. A casting gap is left between the reactor housing 13 and the reactor core post. At this time, the reactor housing 13 and the reactor core post are actually placed on the insulating plate 19. Then, epoxy resin is poured into the casting gap. After the epoxy resin solidifies, the reactor housing 13 and the reactor core post are cast into one piece; the entire reactor is then completed. Afterwards, the entire structure needs to be removed to unload the material. In this embodiment, this is accomplished by the lifting mechanism 17. Accordingly, the lifting mechanism 17 drives the positioning column 3 to move downward, so that the positioning column 3 disengages from the heat dissipation hole 15 of the reactor housing 13. The lifting position of the positioning column 3 does not need to completely disengage from the heat dissipation hole 15. It is only necessary to ensure that the positioning column 3 does not obstruct the disengagement of the reactor housing after moving downward. After the reactor housing 13 is no longer restricted by the positioning column 3, the reactor housing 13 and the reactor core column cast integrally inside are removed, thus completing the unloading of the entire device. At this time, the reactor housing 13 and the reactor core column are actually cast integrally on the insulation plate 19. The insulation can be processed when installing the upper yoke plate and the lower upper yoke plate. The casting work of the entire reactor housing 13 and the core column is also completed accordingly.

[0058] The above embodiments are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
