Description

Technical Field

[0001] The invention relates to the technical field of reactor manufacturing and assembly, and specifically proposes an automatic manufacturing device for a three-dimensional wound core reactor iron core. Background Art

[0002] Reactor is an electrical device used in power system, mainly used to provide inductance, so as to achieve the functions of current limiting, filtering, reactive power compensation, etc.; the core part of the reactor has a variety of structures. The three-dimensional wound core reactor core is a special reactor core structure, generally composed of three core columns arranged in an equilateral triangle, also known as a three-dimensional triangular wound core. Figure 3 and Figure 5 shown.

[0003] During the manufacturing process of the three-dimensional triangular wound core, three independent core columns need to be assembled to form an equilateral triangle structure. After the assembly is completed, the three core columns need to be fixed together by some method such as insulating tape winding, epoxy resin potting, and special fixing parts. Among them, insulating tape winding is the most common method of combination and fixing, and the most common method is to wrap the insulating tape around the contact point of the two core columns to achieve binding and winding fixation.

[0004] In actual operation, assembly and docking is an important part of the whole operation, which affects the overall assembly quality of the three-dimensional triangular wound core. In the existing related equipment, three independent assembly racks are generally provided for core column assembly and movement and transportation, and the assembly racks are only equipped with clamping plates for upper and lower clamping of the core column window holes and assembly clamping. In actual assembly, the following problems obviously exist: 1) The three assembly racks independently move the core column to complete the assembly, and adopt independent upper and lower clamping, independent pushing and moving clamping, and lack of synchronization of operation, so assembly errors are prone to occur in the assembly method.

[0005] 2) During assembly, the core columns are moved closer to each other by three assembly racks to complete the assembly. During assembly, the core columns are generally observed by naked eyes to see whether they are properly spliced. Therefore, when performing multiple batches of assembly operations, there are large differences in the assembly contact pressures between the core columns. Improper operation can easily cause excessive assembly movement, resulting in extrusion deformation between the core columns, affecting the molding quality of the core. Summary of the invention

DETAILED DESCRIPTION

[0030] 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.

[0031] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, an automatic manufacturing device for a three-dimensional wound core reactor core is used for Figure 3 and Figure 5The three core columns 61 in the three-dimensional triangular wound core 6 are automatically assembled. If the three core columns 61 are actually fixed by winding with insulating tape, the device can be installed in the automatic winding processing system of insulating tape. The device includes a central frame 1, which includes a main frame 11 and a lifting frame 12 vertically slidably mounted at the bottom of the main frame 11. The main frame 11 is equipped with a lifting drive assembly 13 that drives the lifting frame 12 to lift and slide. The main frame 11 includes a conduit column 111 in a circular tube structure; the lifting frame 12 includes a telescopic column 121 slidably mounted at the bottom of the conduit column 111 by means of a spline and a keyway. In this embodiment, the inner wall of the conduit column 111 is processed with a keyway, and the outer wall of the telescopic column 121 is processed with a spline that matches the keyway; three upper guide beams 112 are evenly distributed and welded on the circumference of the conduit column 111, and three lower guide beams 122 are evenly distributed and welded on the circumference of the telescopic column 121; the length direction of both the upper guide beam 112 and the lower guide beam 122 are arranged along the radial direction of the conduit column 111. The lifting drive assembly 13 includes a driving motor 131 fixed to the top of the conduit column 111 by bolts and a screw 132 welded on the output shaft of the driving motor 131, the screw 132 passes through the central axis of the conduit column 111, and an internal threaded hole is arranged in the telescopic column 121, and the screw 132 is threadedly mounted in the internal threaded hole.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, the three upper guide beams 112 on the main frame 11 are respectively equipped with a fixture assembly 2; the three lower guide beams 122 on the lifting frame 12 are respectively equipped with a fixture assembly 2; two sets of fixture assemblies 2 are installed on the main frame 11 and the lifting frame 12, and the two sets of fixture assemblies 2 are arranged in a mirror image in the vertical direction. The fixture assembly 2 includes a horizontal component 21 for horizontal contact with the core column 61, and the horizontal component 21 includes a roller seat 211 and a plurality of contact rollers 212 horizontally rotatably installed on the roller seat 211, and the axial direction of the contact roller 212 is arranged parallel to the radial direction of the catheter column 111; the roller seat 211 in the fixture assembly 2 installed on the main frame 11 is slidably installed on the upper guide beam 112, and the roller seat 211 is located below the contact roller 212; the roller seat 211 in the fixture assembly 2 installed on the lifting frame 12 is slidably installed on the lower guide beam 122, and the roller seat 211 is located above the contact roller 212. Each horizontal component 21 is correspondingly equipped with a side thrust component 22 that pushes and contacts the side wall of the core column 61; the side thrust component 22 includes a side thrust plate 221 that is horizontally rotatably mounted on the roller seat 211 away from the end of the central frame 1, and two push-pull cylinders 222 are horizontally fixed on the side of the roller seat 211 that is away from the contact roller 212. The output ends of the two push-pull cylinders 222 are correspondingly hinged to a No. 1 connecting rod 223, and the other end of the No. 1 connecting rod 223 is hinged to the side thrust plate 221. Driven by the push-pull cylinder 222 through the No. 1 connecting rod 223, the side thrust plate 221 flips between a vertical state and an inclined state. In this embodiment, when the output rod of the push-pull cylinder 222 is fully extended, the side thrust plate 221 is in a vertical state, and when the output rod is fully retracted, the side thrust plate 221 is in an inclined state and is close to horizontal. The small inclination angle has a certain protective effect on the core column after placement. In order to realize the linkage of the two clamp assemblies 2 distributed vertically up and down, a series component 3 is connected between the two roller seats 211 in the two clamp assemblies 2 arranged vertically opposite to each other. The series component 3 includes a square guide column 31 welded to the bottom end of the upper roller seat 211 and a square guide sleeve 32 welded to the top end of the lower roller seat 211. The square guide column 31 is slidably installed in the square guide sleeve 32.

[0034] During the actual assembly operation, the core column 61 can be lifted by a lifting device or transported by a forklift. As the core column 61 is lifted and moved, the two clamp assemblies 2 arranged opposite to each other will synchronously extend into the window hole of the core column 61. In order to facilitate the extension into the window hole, the side push plate 221 is installed in a flippable manner. Before extending into the window hole, the side push plate 221 is in a nearly horizontal state, and at this time, the window hole of the core column 61 is overlapped and placed on a group of contact rollers 212 of the upper clamp assembly 2; before extending into the window hole, the side push plate 221 is placed in a flippable manner. After the window hole, under the synchronous drive of the two push-pull cylinders 222, the two No. 1 connecting rods 223 drive the side push plates 221 to flip to a vertical state; then, in order to keep the core column 61 in a stable state during assembly, the lifting drive assembly 13 drives the lifting frame 12 to descend, and the three clamp assemblies 2 below descend synchronously, so that a group of contact rollers 212 of the lower clamp assembly 2 also contact the window hole of the core column 61, and then the core column 61 is stably clamped between the upper and lower groups of contact rollers 212.

[0035] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the bottom of the lifting frame 12 is equipped with an assembly drive component 4 for driving two vertically oppositely arranged clamp assemblies 2 to move synchronously so that the three iron cores 6 are assembled; the assembly drive component 4 includes a driving cylinder 41 assembled in the internal threaded hole of the telescopic column 121 and fixed to the bottom end of the telescopic column 121 by screws, and the output end of the driving cylinder 41 is hinged with three No. 2 connecting rods 42, and the three No. 2 connecting rods 42 are matched one by one with the three clamp assemblies 2 assembled on the lifting frame 12; the other end of the No. 2 connecting rod 42 is hinged to the roller seat 211 at the corresponding position.

[0036] When the two clamp assemblies 2 are clamped in the window holes of the core column 61 from top to bottom, the three core columns 61 can be automatically assembled through the assembly drive component 4. Specifically, when the output end of the driving cylinder 41 extends downward, the roller seat 211 can be driven by the No. 2 connecting rod 42 to make the clamp assembly 2 as a whole move toward the center of the central frame 1. Under the connection of the serial components 3, the upper clamp assembly 2 moves synchronously with the lower clamp assembly 2. During the movement, the upper and lower clamp assemblies 2 drive the core column 61 to move closer, and the core columns 61 randomly contact each other, so that under the auxiliary rolling of the upper and lower sets of contact rollers 212, the core column 61 actively adjusts its position in the radial direction perpendicular to the catheter column 111, and finally, under the push and clamping of the side push plate 221, the three core columns 61 are automatically spliced ​​and assembled, achieving Figure 4 and Figure 5 Assembled state shown.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the main frame 11 is also equipped with an adjustable limit mechanism 5 that is in contact with the serial component 3 to limit the moving position of the clamp assembly 2. Three slide rails 1111 are evenly distributed and welded on the circumference of the catheter column 111, and the slide rails 1111 are arranged radially along the catheter column 111; the adjustable limit mechanism 5 includes three positioning blocks 51 that are mounted on the three slide rails 1111 in a one-to-one correspondence, and the three positioning blocks 51 are arranged in a one-to-one correspondence with the three serial components 3; the positioning block 51 includes a slider 511 that is slidably mounted on the slide rail 1111, and a limit baffle 512 that is in contact with the outer wall of the square guide sleeve 32 is welded relatively vertically on one end of the slider 511 away from the catheter column 111. Two guide hole plates 513 are relatively vertically welded between the slider 511 and the limit baffle 512, and an inclined guide hole 5131 is opened on the guide hole plate 513. The catheter column 111 is equipped with an adjustment component 52 that drives the three positioning blocks 51 to move and adjust synchronously. A threaded section 1112 is provided on the catheter column 111, and the adjustment component 52 includes a driving screw sleeve 521 threadedly mounted on the threaded section 1112; a matching cylinder 522 is rotatably mounted on the driving screw sleeve 521, and three driving ear blocks 5221 corresponding to the three positioning blocks 51 are welded on the circumference of the matching cylinder 522, and the driving ear block 5221 is located between the two guide hole plates 513, and a driving pin 5222 that rolls along the inclined guide holes 5131 of the two guide hole plates 513 is horizontally rotatably mounted on the driving ear block 5221.

[0038] In this embodiment, in order to ensure the effective tightness of the three core columns 61 at the assembly point and avoid mutual extrusion and deformation between the core columns 61 caused by excessive tightness, the adjustable limit mechanism 5 can be adjusted in advance according to the structural dimensions of the core column 61 and the assembly molding dimensions. During adjustment, the matching cylinder 522 can be driven to rise or fall by rotating the drive screw sleeve 521, and then the guide hole plate 513 can be driven by the drive pin 5222 to make the positioning block 51 slide along the slide rail 1111 to adjust the position of the limit baffle 512 relative to the center of the guide tube column 111, so that in the actual assembly process, when the series component 3 moves with the upper and lower clamp assemblies 2, the square guide sleeve 32 will contact the limit baffle 512, so that the clamp assembly 2 cannot move out of place, so that the side push plate 221 can complete the effective contact assembly between the core columns 61 while avoiding excessive extrusion contact between the core columns 61, so as to ensure the overall assembly molding quality of the triangular three-dimensional wound iron core 6.

[0039] The present invention provides an automatic manufacturing device for the iron core of a three-dimensional wound iron core reactor, which is provided with two groups of clamp assemblies 2 distributed up and down, the spacing between the upper and lower groups of clamp assemblies 2 is adjustable, and the two clamp assemblies 2 distributed vertically correspondingly up and down are arranged in linkage, and the clamp assembly 2 is provided with a horizontal component 21 for horizontally contacting with a core column 61 and a side push component 22 for lateral pushing and clamping the core column 61. During actual assembly, the upper and lower groups of clamp assemblies 2 can be synchronously driven by an assembly drive component 4, thereby completing the automatic assembly of multiple core columns 61. The assembly operation has high synchronization, which greatly reduces the assembly error existing in the assembly method adopted by the existing assembly equipment; in addition, an adjustable limit mechanism 5 for corresponding adjustment to different sizes of the iron core 6 is also installed, which can realize the assembly limit of the core column 61, ensure the effective assembly contact between the core columns 61, and avoid excessive extrusion and deformation between the core columns 61, thereby ensuring the assembly molding quality of the iron core 6 of the same size.
