Description

Technical Field

[0001] This utility model belongs to the field of transformer component manufacturing, specifically an auxiliary assembly device for three-dimensional wound iron cores. Background Technology

[0002] The three-dimensional coiled iron core is composed of three single-frame iron cores assembled at a specific angle. During assembly, the three single-frame iron cores are erected, and any two adjacent single-frame iron cores form a 60° angle. They are then bound together to form the three-dimensional coiled iron core.

[0003] The traditional assembly process relies entirely on manual operation. First, one person manually flips the first single-frame iron core into an upright position. Then, a second person aligns the second single-frame iron core along the window and uses steel straps to pack the two single-frame iron cores together. Then, the third single-frame iron core is hoisted. At this time, one person needs to continuously hold the two single-frame iron cores that have been positioned, while another person completes the final packing operation to complete the assembly.

[0004] The above assembly process has the following drawbacks: First, it involves high labor costs and intense labor, and there are safety hazards such as core slippage and injury during operation. Second, manual flipping is inefficient, and positioning accuracy is difficult to guarantee, which can easily lead to rigid collisions between individual core frames, causing quality problems such as dents, damage, or even structural cracks on the surface of the core frames. Utility Model Content

[0005] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide an auxiliary assembly device for three-dimensional coiled iron cores, thereby reducing manual labor intensity and safety hazards, and improving flipping efficiency and positioning accuracy.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An auxiliary assembly device for a three-dimensional wound iron core includes a base and a flipping frame hinged to the base via a first hinge; a first linear drive element and a second linear drive element are provided on the base.

[0008] The drive end of the first linear drive element is hinged to the tilting frame through the second hinge. The working direction of the first linear drive element is set at an angle to the horizontal direction to achieve tilting and pushing of the tilting frame.

[0009] The driving end of the second linear drive element acts on the end of the tilting frame away from the first hinge, and the working direction of the second linear drive element is vertical to achieve vertical lifting of the tilting frame.

[0010] The first linear drive element and the second linear drive element constitute a cooperative drive mechanism, which drives the tilting frame to tilt around the first hinge.

[0011] As a limitation of this utility model, it also includes a movable frame slidably disposed on the flipping frame and a third linear drive element fixed on the flipping frame. The drive end of the third linear drive element is connected to the movable frame. The movable frame is arranged parallel to the flipping frame and the movable frame makes linear reciprocating motion in the direction of approaching or moving away from the flipping frame.

[0012] As a further limitation of this utility model: a connecting plate is fixedly provided at one end of the flipping frame near the base, and a slide rail is fixedly provided on the connecting plate, the slide rail extending along the length direction of the base; a slider is fixedly provided at the bottom end of the movable frame, and the slider is slidably locked onto the slide rail.

[0013] As another limitation of this utility model: a support frame is fixedly provided at the end of the flipping frame away from the first hinge member, the support frame extends along the length direction of the base, and the length of the support frame is equal to the distance between the flipping frame and the ground when the flipping frame is in a horizontal state.

[0014] As a further limitation of this utility model: the first linear drive element, the second linear drive element, and the third linear drive element are all hydraulic cylinders.

[0015] By adopting the above technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows:

[0016] This utility model includes a base, a tilting frame, a first linear drive element, and a second linear drive element. The first linear drive element tilts and pushes the tilting frame, while the second linear drive element lifts it vertically. Together, they form a coordinated drive mechanism that drives the tilting frame to tilt around a first hinge. In implementation, after the tilting frame tilts to a horizontal position, the iron core is secured to it. Then, the first and second linear drive elements drive the tilting frame to tilt to an upright position, at which point the iron core is upright. This structure eliminates the need for manual tilting of the iron core and continuous hand support, saving time and effort and reducing safety hazards. Furthermore, when splicing three single-frame iron cores into a three-dimensional wound iron core, the three devices are simply arranged at intervals, with adjacent devices at 120° intervals. Each device tilts one single-frame iron core. After all three single-frame iron cores are tilted to an upright position, they are then secured and spliced ​​into a three-dimensional wound iron core. Using three devices to tilt the single-frame iron core is highly efficient and provides high tilting positioning accuracy, avoiding the problem of collisions between adjacent single-frame iron cores caused by manual tilting.

[0017] In summary, this invention enables automated flipping of single-frame iron cores, reducing safety hazards, lowering manual labor intensity, and improving flipping efficiency and positioning accuracy. This invention is applicable to the three-dimensional wound iron core production process in the transformer manufacturing industry, and is used to assist in the flipping of single-frame iron cores.

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and do not constitute a limitation thereof.

[0028] The directional terms or positional relationships such as "up," "down," "left," "right," "front," and "back" used in the embodiments are based on the drawings in this utility model specification. Figure 1 The orientation relationships are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component must have a specific orientation, or that it must be constructed and operated in a specific orientation.

[0029] like Figures 1 to 7As shown, this embodiment includes a base 1, a flipping frame 2, a first linear drive element 3, and a second linear drive element 4. The first linear drive element 3 and the second linear drive element 4 constitute a cooperative drive mechanism, which drives the flipping frame 2 to flip around the first hinge 6, thereby realizing the automatic flipping of the single-frame iron core tied to the flipping frame 2 and making it stand upright.

[0030] 1. Tilting rack 2;

[0031] The tilting frame 2 is hinged to the base 1 via a first hinge 6. The first hinge 6 is existing technology and includes a first ear plate 61 fixed to the base 1, a second ear plate 62 fixed to the tilting frame 2, and a first pin 63 passing between the first ear plate 61 and the second ear plate 62, allowing the tilting frame 2 to move along... Figure 1 Rotate in the direction of the middle arrow.

[0032] II. First linear drive element 3 and second linear drive element 4;

[0033] The first linear drive element 3 and the second linear drive element 4 are both mounted on the base 1. In this embodiment, both the first linear drive element 3 and the second linear drive element 4 are existing hydraulic cylinders, but they can also be replaced with any existing structure capable of providing linear driving force.

[0034] The driving end of the first linear drive element 3 is hinged to the tilting frame 2 via the second hinge 7. Here, the driving end refers to the piston rod end 8 of the hydraulic cylinder. The piston rod end 8 is hinged to the tilting frame 2 via the second hinge 7. The structure of the second hinge 7 is existing technology, including a third ear plate 71 fixed on the side of the tilting frame 2 facing the base 1 and a second pin 72 passing through the third ear plate 71. The piston rod end 8 is rotatably sleeved on the pin. The first linear drive element 3 is also hinged to the base 1. In this embodiment, there are two first linear drive elements 3.

[0035] The working direction of the first linear drive element 3 is set at an angle to the horizontal direction to achieve tilting and pushing of the tilting frame 2. In this embodiment, the horizontal direction refers to the left and right directions. Specifically, in this embodiment, the angle β between the first linear drive element 3 and the horizontal direction is 36°, which can provide a driving force to the tilting frame 2 in the direction of the upper left corner.

[0036] The driving end of the second linear drive element 4 acts on the end of the tilting frame 2 furthest from the first hinge 6. This furthest end of the tilting frame 2 refers to its top end, and here the driving end also refers to the piston rod end 8 of the hydraulic cylinder. The second linear drive element 4 operates vertically to achieve vertical lifting of the tilting frame 2. Figure 4 , 1As shown, when the flipping frame 2 is in a horizontal state and needs to be flipped to a vertical state, the second linear drive element 4 lifts the top of the flipping frame 2 vertically upward, and the first linear drive element 3 pushes the flipping frame 2 at an angle along the upper left corner, so as to realize the flipping frame 2 flipping around the first hinge 6.

[0037] III. Moving frame 9, third linear drive element 5;

[0038] like Figure 1-3 As shown, this embodiment also includes a movable frame 9 slidably mounted on the tilting frame 2 and a third linear drive element 5 fixed on the tilting frame 2. The third linear drive element 5 also uses an existing hydraulic cylinder. The drive end of the third linear drive element 5 is connected to the movable frame 9, that is, the piston rod end of the hydraulic cylinder is connected to the movable frame 9, so that the movable frame 9 can perform linear reciprocating motion in the direction of approaching or moving away from the tilting frame 2. See [reference needed] Figure 5 , 6 .

[0039] Specifically, the movable frame 9 and the flipping frame 2 are arranged parallel to each other, and a connecting plate 10 is fixedly provided at one end of the flipping frame 2 near the base 1, such as... Figure 2 , 3 As shown, the connecting plate 10 extends horizontally, and a slide rail 11 is fixedly mounted on the connecting plate 10. The slide rail 11 extends along the length direction of the base 1, which in this embodiment also refers to the left and right directions. A slider 12 is fixedly mounted at the bottom of the movable frame 9, and the slider 12 is slidably locked onto the slide rail 11. The sliding method achieved by the slide rail 11 and the slider 12 is existing technology. In this embodiment, there are three slide rails 11, which are arranged at intervals along the front and back directions, and two sliders 12 are slidably mounted on each slide rail 11.

[0040] The function of setting up the movable frame 9 is as follows: Figure 5-7 As shown, after the tilting frame 2 tilts the iron core to an upright position, if the distance between the three iron cores is not in place, the third linear drive element 5 can be used to drive the moving frame 9 to move the single-frame iron core to the left, so that the three single-frame iron cores can contact each other. This further improves the positioning accuracy of the single-frame iron core and avoids the problem of collision between single-frame iron cores due to poor control of the travel distance by manual adjustment.

[0041] IV. Support frame 13;

[0042] like Figure 1 As shown, a support frame 13 is fixedly mounted on the end of the tilting frame 2 away from the first hinge member 6 (i.e., the top of the tilting frame 2). The support frame 13 is fixed to the right side of the top of the tilting frame 2 and extends along the length of the base 1, that is, to the right. The length of the support frame 13 is equal to the distance between the tilting frame 2 and the ground when it is in a horizontal state. In other words, as shown... Figure 4As shown, when the tilting frame 2 is in a horizontal state, the support frame 13 contacts the ground and is used to support the end of the tilting frame 2 to prevent the end of the tilting frame 2 from undergoing unexpected deformation or structural damage due to gravity.

[0043] When using this embodiment, as Figure 7 As shown, three of these devices are arranged at 120° intervals along the circumference. Taking one of these devices as an example: Figure 4 As shown, the tilting frame 2 and the moving frame 9 are in a horizontal state, and the piston rods in the first linear drive element 3 and the second linear drive element 4 are in the retracted state. After the single-frame iron core is placed flat on the moving frame 9, the single-frame iron core and the moving frame 9 are tied and fixed. Then, the first linear drive element 3 and the second linear drive element 4 are operated. The second linear drive element 4 lifts the top of the tilting frame 2 vertically upward, while the first linear drive element 3 tilts and pushes the tilting frame 2 in the direction of the upper left corner, realizing the tilting frame 2 tilting around the first hinge 6. Finally, the tilting frame 2 and the moving frame 9 drive the single-frame iron core to tilt. Figure 5 The vertical position is shown. When the three single-frame iron cores on this device are not in contact and aligned, operate the third linear drive element 5 to drive the moving frame 9 to move the single-frame iron cores linearly to the position shown. Figure 6 At this point, the three single-frame iron cores are in contact. Finally, the three single-frame iron cores are tied together and spliced ​​into a three-dimensional coiled iron core.

[0044] This invention achieves automatic flipping of the single-frame iron core through a first linear drive element 3, a second linear drive element 4, and a flipping frame 2. This results in high flipping positioning accuracy, saves time and effort, and reduces safety hazards. The third linear drive element 5 and a moving frame 9 achieve horizontal displacement of the single-frame iron core, further ensuring positioning accuracy.
