[0001] The utility model belongs to the technical field of transformer manufacturing, and in particular relates to a transformer inserting tool and an inserting system. Background Art

[0002] With the development of the electric power industry, the demand for transformers in various industries is also increasing. In the manufacturing process of transformers, it is necessary to insert the iron core. At present, in the industry, for transformers used in automobiles and industries, the insertion method is mostly to place the rack of silicon steel sheets on the assembly rack. The operator on the assembly rack needs to take the silicon steel sheets from the rack on the assembly rack and then turn around to insert the sheets. Depending on the size of the product's iron core, an operator needs to turn around about 2,000 to 5,000 times. The long time and high labor intensity are not only not conducive to improving work efficiency, but also make the inserting operators prone to occupational diseases such as lumbar muscle injury and lumbar disc herniation. Utility Model Content

[0003] The inventor of the utility model discovered that in order to facilitate the operator to take and place silicon steel sheets and insert the sheets, the iron core and the material rack (with silicon steel sheets) need to be set at a position that is convenient for the operator to handle, that is, next to the operator. However, the transformer cores used in automobiles and industrial purposes are currently large in size. If the iron core and the material rack are set on the same side of the operator, at least one of them will be in a position that the operator cannot reach. As a result, the iron core and the material rack need to be set on both sides of the operator respectively to ensure that the operator can easily access them, that is, the iron core placement position and the material rack placement position are on both sides of the sheet insertion operation position. This also results in the operator having to turn around repeatedly to take and insert the sheets during the sheet insertion process.

[0004] Accordingly, the technical problem to be solved by the present invention is to provide a transformer insertion tooling for the above-mentioned deficiencies existing in the prior art, which has a simple structure, a reasonable layout, simplifies the operation, effectively improves the insertion efficiency, and reduces the operation intensity.

[0010] Furthermore, the transformer insert tooling also includes a movable connecting piece, and the supporting mechanism is provided with a plurality of groups, each group of the supporting mechanism is used to support each material rack respectively, and each group of the supporting mechanism is movably connected to the assembly frame perpendicular to the telescopic direction of the supporting mechanism through a movable connecting piece, so that the spacing between the supporting mechanisms can be adjusted through the movable connecting piece to match the core placement position.

[0011] Furthermore, the movable connecting member includes a guide rail and a slide, the guide rail is arranged on the assembly frame perpendicular to the extension and contraction direction of the supporting mechanism, and the slide is connected to the supporting mechanism and slidably arranged on the guide rail.

[0012] Furthermore, two guide rails are provided, and the two guide rails are arranged in parallel and at intervals. Limiting parts are provided at both ends of the slide. The slide straddles the two guide rails, and the two guide rails are respectively engaged and clamped by the limiting parts at both ends.

[0013] Furthermore, the slide is provided with a fastener which penetrates the slide in the vertical direction and tightens the guide rail through the end.

[0014] The utility model also provides a transformer inserting system, comprising at least one group of inserting stations, each group of the inserting stations is provided with an assembly frame, a material rack and the above-mentioned transformer inserting tooling, each group of the inserting stations includes an inserting operation position, an iron core placement position and a material rack placement position; in one group of the inserting stations, the assembly frame and the iron core placement position are on the same side of the inserting operation position, the connecting end of the supporting mechanism of the transformer inserting tooling is connected to the assembly frame, and the movable end serves as a material rack placement position and can support the material rack to be extended and retracted so that the material rack placement position reaches above the iron core placement position.

The support mechanism itself is a telescopic mechanism, and its connection end is connected to the assembly frame. Therefore, the contracted support mechanism is located on the assembly frame as a whole, which can avoid occupying the space above the core placement position after contraction, so it will not affect the normal lifting of the transformer core.

[0035] Example 1

[0036] The transformer inserting tool of this embodiment can be used to assist the inserting operation of transformer cores for automobile and industrial purposes. The tool includes a supporting mechanism 2, such as Figures 1 to 5 As shown, the supporting mechanism 2 is a telescopic mechanism that can be extended and retracted. The supporting mechanism 2 is arranged along the connecting line direction of the core placement position and the insert operation position, and the extension length is not less than the distance between the core placement position and the assembly frame 1. One end of the supporting mechanism 2 is connected to the assembly frame 1 as a connecting end, and the height is higher than the core placement position. The assembly frame 1 connected to the connecting end is on the same side of the insert operation position as the core placement position, and the assembly frame 1 is farther away from the insert operation position than the core placement position. Fig.11 As shown, the other end of the supporting mechanism 2 is used as a movable end for supporting the material rack 3. The movable end is moved relative to the connecting end by extending the supporting mechanism 2 to support the material rack 3 to reach above the core placement position.

[0037] Specifically, the supporting mechanism 2 is a telescopic mechanism that can extend and contract in the horizontal direction. The telescopic direction is toward the core placement position. When contracted, the supporting mechanism 2 is completely retracted at the connection end connected to the assembly frame 1. When extended, the active end of the supporting mechanism 2 extends above the core placement position.

[0038] In this embodiment, a retractable supporting mechanism 2 is provided to support the material rack 3 for movement, so that the material rack 3 is moved above the core placement position, so that the material rack placement position and the core placement position are located on the same side of the sheet insertion operation position, that is, the operator can face the material rack and the core at the same time, so that the operator at the sheet insertion operation position can take the sheet from the material rack placement position and insert the sheet into the core placement position without turning around. This reasonable layout method changes the original sheet insertion method. Since the operator's turning around is eliminated, it can improve the efficiency of sheet insertion while also being ergonomic, thereby protecting the operator's health to the greatest extent.

[0039] The extended supporting mechanism 2 enables the supported material rack 3 to reach above the core placement position, which not only fully utilizes the vertical space, but also creatively considers the use of the vertical space and cleverly supports through the telescopic mechanism to break the inherent layout thinking that the material rack placement position and the core placement position cannot be located on the same side of the inserting operation position. The supporting mechanism 2 itself is a telescopic mechanism, and its connecting end is connected to the assembly frame. Therefore, the contracted supporting mechanism 2 is located on the assembly frame 1 as a whole, which can avoid occupying the space above the core placement position after contraction, so it will not affect the normal lifting of the transformer core. And as the silicon steel sheets are continuously inserted into the core, the operator can perform telescopic operation on the supporting mechanism 2 as needed to make it reach the position where the sheet is being inserted, and the supporting mechanism 2 can be easily pulled out and pushed in manually.

[0040] In this embodiment, the supporting mechanism 2 includes a telescopic component 21, such as Figure 6 As shown, the telescopic assembly 21 includes a plurality of sleeves 211, and each sleeve 211 is movably sleeved from the inside to the outside in sequence. Figures 7 to 10 As shown, the outermost sleeve 211 is connected to the assembly frame 1 as a connection end, and the inner sleeve 211 can be relatively movable and withdrawn to achieve the extension of the telescopic component 21. The material rack 3 is placed on the telescopic component 21 after it is extended to a set length. The set length can be selected according to the specific position of the core placement position, which will not be described in detail here.

[0041] Specifically, in two adjacent layers of sleeves 211, the inner sleeve 211 extends from the port of the outer sleeve 211 toward the core placement position, and a stopper 212 protruding outward is provided on the extended end of the inner sleeve 211, so that the extended end size (width or diameter) of the inner sleeve 211 is larger than the port size (width or diameter) of the outer sleeve 211, so as to prevent the inner sleeve 211 from being completely embedded in the outer sleeve 211 and making it difficult to telescope. Each sleeve 211 of this embodiment can be made of square steel structure, the material is easy to obtain and manufacture, and the structural strength is high, and the load-bearing capacity is strong. The extended end can also be fastened at the support platform (i.e., the product clamp) to further increase its load-bearing capacity, which can basically reach 3.5 tons of load-bearing. In this embodiment, each telescopic component 21 is provided with three layers of sleeves 211, so that the telescopic component 21 can be telescopically changed between 2000mm and 4750mm. In other implementations, the number of the sleeves 211 of the telescopic assembly 21 may be increased or decreased depending on the situation.

[0042] In this embodiment, at least one group of two adjacent layers of sleeves 211 may also be provided with a fastener that penetrates the outer sleeve 211 in the radial direction and presses against the inner sleeve 211 through the end. By tightening the fastener, the relative movement between the inner sleeve 211 and the outer sleeve 211 can be limited, which ensures that the telescopic assembly 21 can be extended and maintained at the required position. The inner end of the fastener presses against the inner sleeve, and the outer end may be provided with a rotating handle to facilitate the operation of tightening or loosening. The setting position and number of the fastener can be selected as needed. In this embodiment, it is only set through the outermost sleeve 211 and is not shown in the figure.

[0043] In this embodiment, the transformer insert tooling also includes a movable connection member 4, and the supporting mechanism 2 includes multiple groups of telescopic components 21, each group of telescopic components 21 is used to jointly support the material rack 3, and the outermost sleeve 211 of the telescopic component 21 is movably connected to the assembly frame 1 through the movable connection member 4 perpendicular to the telescopic direction of the supporting mechanism 2, so that the spacing between the telescopic components 21 can be adjusted to match the length of the material rack 3 through the movable connection member 4 to ensure that the material rack 3 can be supported. The supporting mechanism 2 of this embodiment specifically uses two groups of telescopic components 21 to support one material rack 3. In other embodiments, it can also be appropriately increased depending on the length and weight of the material rack.

[0044] In this embodiment, the supporting mechanism 2 is provided with multiple groups, each group of the supporting mechanism 2 is used to support each material rack 3 respectively, and each group of the supporting mechanism 2 (that is, the telescopic components 21 of each group of the supporting mechanism 2) is movably connected to the assembly frame 1 through a movable connecting piece 4 perpendicular to the telescopic direction of the supporting mechanism 2, so as to adjust the spacing between the supporting mechanisms 2 through the movable connecting piece 4 to match the placement position of the iron core. The supporting mechanism 2 of this embodiment is provided with four groups, that is, this embodiment is provided with a total of eight groups of telescopic components 21, distributed along the length direction of the assembly frame 1, which can realize the simultaneous support of four material racks 3, that is, 4 racks of silicon steel sheets can be placed at the same time, meeting the requirements of inserting four window widths of the upper yoke of the transformer core at the same time. In other embodiments, the number of the supporting mechanisms 2 can also be adjusted according to the situation of the transformer core.

[0045] By setting up movable connecting parts, not only the distance between the telescopic components 21 in each group of supporting mechanisms 2 can be adjusted, but also the distance between two adjacent groups of supporting mechanisms 2 can be adjusted. Therefore, the scope of application is wider, and it can be applicable to the support of various silicon steel sheets and various transformer core inserts.

[0046] In this embodiment, the movable connecting member 4 includes a guide rail 41 and a slide 42. Figure 7 As shown, the guide rail 41 is arranged on the assembly frame 1 perpendicular to the telescopic direction of the supporting mechanism 2, and the slide 42 is connected to the supporting mechanism 2 (specifically, connected to the outermost sleeve 211 of the telescopic component 21 in the supporting mechanism 2) and is slidably set on the guide rail 41.

[0047] In this embodiment, two guide rails 41 are provided, and the two guide rails 41 are arranged in parallel and spaced apart. Limiting parts are provided at both ends of the slide. The slide straddles the two guide rails and is engaged with the two guide rails through two limiting parts.

[0048] Specifically, the slide is an inverted U-shaped structure, and its length direction is connected to the outermost sleeve 211 along the telescopic direction of the telescopic assembly 21, and both ends of the length direction are provided with limit parts, and the limit parts include a first limit part 421 and a second limit part 422. The first limit part 421 is connected to the slide body, and the second limit part 422 is connected to the first limit part 421. A horizontal gap is provided between the first limit part 421 and the second limit part 422. The guide rail 41 is made of C-shaped steel, and the C-shaped steel openings of the two guide rails 41 are arranged oppositely. When the slide 42 cooperates with the guide rail 41, the first limit part 421 and the second limit part 422 are respectively clamped on the upper and lower sides of the horizontal part of the top of the C-shaped steel.

[0049] In this embodiment, a fastener is provided on the slide 42, which passes through the slide 42 in the vertical direction and presses against the guide rail 41 through the end. By setting up this fastener structure, the relative movement between the slide 42 and the guide rail 41 can be limited, so as to ensure that each telescopic assembly 21 can be kept at a desired position on the guide rail 41. The bottom end of the fastener presses against the guide rail, and a rotating handle can be provided at the top end to facilitate personnel to operate to press or loosen. The setting position and number of the fastener can be selected as needed, and this embodiment is not shown in the figure.

[0050] This embodiment provides a tooling scheme for forward insertion with reliable structure and convenient manufacture to solve the problems of high labor intensity and long insertion time of the original insertion method, so as to improve the efficiency of insertion and reduce the labor intensity of workers. The specific scheme is that the tooling pre-installed on the assembly frame 1 can be steplessly adjusted according to the length of the product (transformer core) in the length direction of the assembly frame 1 by the movable connecting part 4, and a total of 8 sets of telescopic components 21 are set. When inserting the sheet, the telescopic component 21 in the tooling is pulled out to the top of the transformer body, and then the material rack 3 of the silicon steel sheet is hung on the telescopic component 21. The length direction of the material rack 3 is parallel to the length direction of the transformer, and 4 racks of silicon steel sheets can be placed at the same time to meet the requirements of inserting the sheet of 4 window widths of the upper yoke at the same time. When inserting the sheet, the operator faces the sheet material, and can insert the sheet by picking up the silicon steel sheet, reducing the turning action to achieve the purpose of reducing labor intensity.

[0051] Example 2

[0052] The transformer inserting system of the present embodiment comprises at least one group of inserting stations, each group of inserting stations is provided with an assembly frame 1, a material rack 3 and the transformer inserting tooling in Example 1, each group of inserting stations comprises an inserting operation position, an iron core placement position and a material rack placement position; in one group of inserting stations, the assembly frame 1 and the iron core placement position are on the same side of the inserting operation position, the connecting end of the supporting mechanism 2 of the transformer inserting tooling is connected to the assembly frame 1, and the movable end as the material rack placement position can support the material rack 3 to be extended and retracted so that the material rack placement position reaches above the iron core placement position.

[0053] In this embodiment, the system includes two groups of inserting stations, such as Fig.11 As shown, one side of the assembly rack 1 along the length direction is used as the inserting operation position, and the other side is used as the connection position of the supporting mechanism 2. The assembly racks 1 of the two groups of inserting positions are arranged in parallel and spaced apart, and the sides of the two assembly racks 1 with the inserting operation position are adjacent (the iron core can be set to a state where the upper surface is flush with the inserting operation position, and the operator can walk from the inserting operation position to the iron core to complete the inserting of it), the iron core placement position is located between the two assembly racks 1, and the iron core placement position, the inserting operation position on one assembly rack 1 and the material rack placement position of the supporting mechanism 2 on the other assembly rack 1 are used as a group of inserting positions. In this setting structure, when performing the inserting operation, the supporting mechanism 2 on one assembly rack 1 extends and crosses the idle inserting operation position on the assembly rack 1 to reach above the iron core placement position, and the operator operates on the inserting operation position on the other assembly rack 1. The structural layout is more reasonable, making full use of the space on both sides of the iron core placement position, and the arrangement of the inserting tooling does not change the original layout of the assembly rack 1 and the iron core placement position, but adopts the opposite side grouping method.

[0054] In this embodiment, the assembly frame 1 has a two-step structure, wherein the first step surface 11 with a lower height serves as the insert operation position, and the second step surface 12 with a higher height is connected to the supporting mechanism 2, and the core placement position is not higher than the insert operation position to ensure that the height of the supporting mechanism 2 is higher than the core placement position.

[0055] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
