[0002] The three-dimensional wound core is a core component widely used in transformers, and its structural feature is that silicon steel sheets or amorphous alloys are wound into a core in a certain shape and manner to achieve higher electrical performance and mechanical stability. The traditional core assembling method mainly adopts vertical assembly, that is, the core single frame is spliced in a vertical state. This method has problems such as high operation difficulty, high alignment difficulty, and low assembly efficiency. Especially in the assembly process of large-scale cores, workers need to use lifting equipment due to the high assembly height, which increases the complexity and safety risk of operation.

[0045] As shown in Figure 1 and Figure 2 , the core single frame 11 is in the shape of a rectangular ring, and three core single frames 11 are enclosed to form a core column 10 in the shape of a triangular prism. As shown in Figure 1 , among the inner side surfaces of the core single frame 11, the inclined surface (hereinafter referred to as the inner inclined surface 111) extending along the length direction thereof forms a 30° angle with the large surface of the core single frame 11, and after assembly, two inner inclined surfaces 111 in one core single frame 11 respectively abut against the inner inclined surfaces 111 on the corresponding sides of the adjacent core single frames 11. The volume of the core single frame 11 is large, and the traditional core assembly method is to assemble the core single frame 11 in a vertical state, which requires strict verticality of the single core single frame 11 during assembly, making this method difficult to operate, difficult to align, and low in assembly efficiency.

[0046] To solve the above problems, the present embodiment provides a three-dimensional wound core assembly method, which can reduce the operation difficulty of assembly, align more accurately, and improve the assembly efficiency. As shown in Figures 3-10 , the three-dimensional wound core assembly method comprises:

[0047] S10: As shown in Figure 3 and Figure 4 , three core single frames 11 are prepared, two of which are placed horizontally on the assembly mechanism 20 and are limited, and the two core single frames 11 are arranged in the width direction of the core single frame 11;

[0048] S20: As shown in Figure 5 , the assembly mechanism 20 drives the two core single frames 11 to rotate 60° towards the middle of the two core single frames 11, and as shown in Figure 6 , the two core single frames 11 are further driven to approach each other until the inner inclined surfaces 111 of the two core single frames 11 abut against each other;

[0049] S30: As shown in Figures 7-9 , the third core single frame 11 is horizontally hoisted and placed on the first two core single frames 11, so that the two inner inclined surfaces 111 of the third core single frame 11 abut against the two core single frames 11, respectively;

[0050] S40: As shown in Figure 10As shown, three iron core single frames 11 are bundled and fixed to form the iron core limb 10 by using the clamp assembly 12.

[0051] The assembling method of the three-dimensional wound core is that two iron core single frames 11 are first placed on the assembling mechanism 20, the assembling mechanism 20 is used to rotate and move the corresponding iron core single frames 11, so that the corresponding inner inclined surfaces 111 of the two iron core single frames 11 abut, at this time, the two iron core single frames 11 are assembled in place, and the third iron core single frame 11 is lifted by the lifting tool 40 and placed between the first two iron core single frames 11 in a horizontal posture. Since the iron core single frames 11 are all horizontally spliced, the two inner inclined surfaces 111 of the third iron core single frame 11 are more easily attached to the corresponding inner inclined surfaces 111 of the other two iron core single frames 11 under the action of gravity, without considering the perpendicularity of the iron core single frame 11, thereby reducing the operation difficulty of assembling, making the alignment more accurate, and improving the assembling efficiency of the iron core limb 10.

[0052] Optionally, as shown in Figure 12 , in S40, the two adjacent iron core single frames 11 are fixed by the plurality of straps 13. Through the above arrangement, the bundling and fixing of the two adjacent iron core single frames 11 can be quickly realized, and the bundling effect of the plurality of straps 13 is more firm.

[0053] Optionally, as shown in Figure 3 and Figure 4 , the assembling mechanism 20 includes a base 21, two jigs 22, and two third driving members 23. The two jigs 22 are pivotally connected to the base 21 at intervals, and each third driving member 23 can drive the corresponding jig 22 to rotate.

[0054] Optionally, the assembling mechanism 20 further includes two horizontal driving members (not shown), which are arranged one-to-one corresponding to the two jigs 22. The horizontal driving members are used to drive the corresponding jigs 22 and third driving members 23 to move in the horizontal direction, so that the two jigs 22 move closer to or farther away from each other.

[0055] Optionally, the assembling mechanism 20 can also drive the iron core single frame 11 to ascend and descend. Specifically, a vertical driving member (not shown in the figure) is installed between the carrier and the base 21, and the vertical driving member can drive the jig 22 to ascend and descend in the vertical direction to meet a more appropriate operation height.

[0056] The jig 22 can be made according to the shape of the iron core single frame 11, and generally includes a clamping jaw and other parts, which will not be described here. It should be noted that the jig 22 and the clamping jaw 122 are arranged to avoid each other when the clamping jaw 122 is fixed after the jig 22 is rotated by 60°.

[0057] Optionally, as shown in Figure 11 and Figure 12As shown, the assembling method of the three-dimensional laminated core further comprises:

[0060] Optionally, the adjusting process comprises at least one of knocking, beating, binding or grinding.

[0061] Optionally, the adjusting process comprises processing of diameter, perpendicularity, angle or flatness.

[0062] The core limb 10 after the adjusting process can meet the process requirements of the core limb 10, forming a qualified product.

[0063] Optionally, as shown in Figure 11 The transferring of the core limb 10 is completed by the lifting tool 40.

Through the above setting, the operator is facilitated to comprehensively adjust the circumference of the core limb 10 and measure the process parameters after the adjustment. The first driving member 312 can be a stepping motor or a servo motor, etc., which is not limited here.

[0065] Optionally, referring to Figure 10 and Figure 12The two ends of the core limb 10 are provided with clamp assemblies 12, the clamp assemblies 12 include a pivot joint 121 and three clamps 122, the pivot joint 121 includes a pivot part 1211 and three connecting arms 1212, the pivot part 1211 extends along the length direction of the core limb 10, the three connecting arms 1212 are uniformly diverged outwardly with the pivot part 1211 as the center, the clamp 122 is in the shape of U, and is correspondingly buckled on the corner of the core limb 10 along the length direction of the core limb 10, and one connecting arm 1212 is clamped between each clamp 122 and the corner of the core limb 10. It can be understood that when the positions of the three core single frames 11 are in place, the clamp assemblies 12 are used for fixing at the ends of the core limb 10, and subsequent transfer to the adjusting mechanism 30 is facilitated, further, the pivot part 1211 in the pivot joint 121 is used as a pivot shaft for subsequent installation on the adjusting mechanism 30, and when the clamp 122 is clamped on the corners of the two adjacent core single frames 11, the clamp 122 is pushed from inside to outside along the extension direction of the connecting arm 1212 while ensuring that the opening faces the axial direction of the core limb 10, until the clamp 122 is tightened by the corner of the core limb 10, so that the clamp 122 exerts a clamping force on the core limb 10.

The installation of the core limb 10 on the frame body 311 is realized.

[0067] Further, the distance between the two sub-frames 3111 is adjustable and lockable. Before the core limb 10 is installed, the distance between the two sub-frames 3111 is adjusted to be large, one of the pivot parts 1211 is inserted into one of the sub-frames 3111, and then the distance between the two sub-frames 3111 is adjusted to be small, so that the other pivot part 1211 is inserted into the other sub-frame 3111.
