Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of transformer coil, in particular to a bidirectional asynchronous telescopic tool for rectangular coil winding and application thereof. BACKGROUND

[0002] The coil of single-phase pole-mounted transformer is mainly in rectangular structure, but the existing mold is designed according to the inner cylinder size of the coil, that is, most of the coil manufacturing molds are one type for one, and a mold can only be used to manufacture one type of coil. The fixed mold cannot be used for other coil products, so a large number of molds are needed to meet the production and processing needs. This increases the production cost of transformer production enterprises and the pressure on storage space. Various specifications of molds not only cause material waste and occupy a large amount of storage space, but also require enterprises to increase the time cost of manufacturing molds, greatly reducing the production efficiency.

[0003] At present, there are one-way synchronous telescopic and bidirectional synchronous telescopic molds on the market, which improve the universality of the coil winding mold to a certain extent. However, the one-way synchronous telescopic mold can only realize synchronous telescoping in one direction, that is, it can realize the adjustment of the fixed long side size or short side size. For application occasions that require telescoping in two directions at the same time or alternately, such as the manufacture of rectangular coils with strong symmetry, the applicability is low. Compared with the one-way synchronous telescopic mold, the bidirectional synchronous telescopic mold can realize size adjustment in two directions, but the long side and the short side need to be adjusted at the same time. The strict requirement of synchronization will limit the adjustable range of process parameters, and if a fault occurs, the mold cannot be used, which seriously affects the product quality and production efficiency. Therefore, the existing mold still cannot be applied to more production scenarios. SUMMARY

[0031] It can be understood that, in the embodiment, the X-axis adjusting piece 221 and the Y-axis adjusting piece 231 are rotated to drive the X-axis tension main push connecting rod 33 and the Y-axis tension main push connecting rod 34 respectively, so as to realize the opening and closing of the present application. The X-axis adjusting piece 221 and the Y-axis adjusting piece 231 are independently arranged on the main body lead screw 2, which can realize asynchronous telescoping in the long direction and the short direction. The present application realizes free adjustment of the size in the long direction and the short direction, the bidirectional size can be changed in the range of 0-45mm respectively, which improves the flexible application degree of the present application, and further improves the universality, so that the present application has a more extensive application scenario.

[0033] In the above embodiment, as shown in Figure 2 The adjusting assembly 21 further comprises two first limiters 24, which are respectively arranged on the sides of the X-axis adjusting member 221 and the Y-axis adjusting member 231 away from the main body frame 1. The first limiters 24 can rotate on the main body screw 2, and limit and lock the X-axis adjusting member 221 and the Y-axis adjusting member 231, respectively. After the X-axis adjusting member 221 and the Y-axis adjusting member 231 rotate on the main body screw 2, the first limiters 24 rotate to and abut against the X-axis adjusting member 221 or the Y-axis adjusting member 231, thereby locking the X-axis adjusting member 221 and the Y-axis adjusting member 231, respectively, and further fixing the positions of the two members, so as to avoid loosening of the two members, thereby making the structure of the present application more stable.

[0034] In the above embodiment, as shown in Figure 3 The X-axis adjusting member 221, the Y-axis adjusting member 231 and the first limiters 24 are all in the shape of a cylinder.

The sliding connection of the sliding block 31 with the first connecting member 32 further makes the structure of the present application more compact, the connection of the sliding block 31 with the X-axis tension main push connecting rod 33 enables the position of the sliding block 31 to move when the X-axis adjusting member 221 rotates, thereby driving the X-axis tension main push connecting rod 33; the connection of the first connecting member 32 with the Y-axis tension main push connecting rod 34 enables the second connecting member 35 to slide on the sliding block 31 when the Y-axis adjusting member 231 rotates, thereby driving the Y-axis tension main push connecting rod 34.

[0036] In the above embodiment, as shown in Figure 3 ,Figure 4 and Figure 5 As shown in FIG. 2 and FIG. 3, the X-axis connecting piece 222 and the Y-axis connecting piece 232 are U-shaped pieces; the first cushion block 223, the second cushion block 233 and the first connecting piece 32 are square pieces. The X-axis connecting piece 222 and the Y-axis connecting piece 232 are U-shaped pieces, which play a clamping role on the X-axis adjusting piece 221 and the Y-axis adjusting piece 231, and facilitate the rotation and sliding of the X-axis adjusting piece 221 and the Y-axis adjusting piece 231, and also facilitate the disassembly. The first cushion block 223, the second cushion block 233 and the first connecting piece 32 are square pieces, which further make the connection between the adjusting assembly 21 and the connecting assembly 3 more stable, thereby improving the production efficiency.

[0037] In the above embodiments, as shown in FIG. 2 and FIG. 3, Figures 1-2 , Figures 6-8 As shown in FIG. 2 and FIG. 3, the telescopic assembly 11 includes two transition plates 111 which are symmetrically connected to the main body framework 1, and the transition plate 111 is provided with a plurality of through holes 113 which are adapted to the X-axis tension connecting rods 112. Each through hole 113 is hingedly connected to one end of the X-axis tension connecting rod 112 which is close to the main body screw rod 2, and the other end of the X-axis tension connecting rod 112 is hingedly connected to the recess 115 on the X-axis tension plate 114 which is parallel to the transition plate 111, and the recess 115 which is close to the main body screw rod 2 is hingedly connected to the X-axis tension main pushing connecting rod 33. A plurality of Y-axis tension connecting rods 116 are symmetrically hingedly connected between the two transition plates 111, and each Y-axis tension connecting rod 116 is hingedly connected to one first mounting groove 118 on the Y-axis tension plate 117 which is parallel to the main body framework 1 and is away from the main body framework 1, and the Y-axis tension plate 117 is provided with a second mounting groove 119 which is close to the main body screw rod 2 and is hingedly connected to one end of the Y-axis tension main pushing connecting rod 34.

[0038] It can be understood that the X-axis tension connecting rod 112 and the Y-axis tension connecting rod 116 are hingedly connected to the transition plate 111, and the X-axis tension connecting rod 112 is hingedly connected to the X-axis tension plate 114, and the Y-axis tension connecting rod 116 is hingedly connected to the Y-axis tension plate 117. When the X-axis adjusting piece 221 is rotated, the X-axis tension main pushing connecting rod 33 is moved, and then the X-axis tension main pushing connecting rod 33 drives the X-axis tension plate 114 and the X-axis tension connecting rod 112, thereby realizing the size change in the long side direction. When the Y-axis adjusting piece 231 is rotated, the Y-axis tension main pushing connecting rod 34 is moved, and then the Y-axis tension main pushing connecting rod 34 drives the Y-axis tension plate 117 and the Y-axis tension connecting rod 116, thereby realizing the size change in the short side direction. The X-axis adjusting piece 221, the Y-axis adjusting piece 231, the X-axis tension main pushing connecting rod 33 and the Y-axis tension main pushing connecting rod 34 are used to cooperate with the X-axis tension connecting rod 112 and the Y-axis tension connecting rod 116, thereby realizing the expansion and contraction of the present application, and the X-axis adjusting piece 221 and the Y-axis adjusting piece 231 are independently arranged on the main body screw rod 2, thereby realizing the bidirectional asynchronous telescopic function.

[0039] In the above embodiment, as shown in Figure 1 and Figure 2 , by adjusting the cooperation among the adjusting assembly 21, the connecting assembly 3 and the telescopic assembly 11, the long side and short side direction sizes can be adjusted freely respectively, the present application can realize the general use of the mold change within the range of 45mm, further improving the general use of the mold. The short side direction size range of the present application is 65-110mm, and the long side direction size range is 75-120mm. Alternatively, the coil winding application of the transformer capacity of 37.5kVA or more products can be met. Alternatively, in order to meet the application of more different size products, subsequent fixed holes can be added on the X-axis tension plate 114 and the Y-axis tension plate 117 respectively, wooden pads are installed, and larger size changes are realized by increasing the wooden pads. According to different specifications of products, four or two wooden pads are selected for transformation and use, and wooden pads are used for processing, which is convenient to operate and has low processing cost.

The second limiting piece 4 is arranged on the main skeleton 1, which can limit the position of the X-axis tension plate 114, avoiding the movement of the X-axis tension plate 114, so as to affect the production efficiency. Figure 4 and Figure 7 , the slot of the first mounting slot 118 faces the tail of the main skeleton 1, and the slot of the second mounting slot 119 faces the end of the main skeleton 1. The slot of the first mounting slot 118 faces the tail of the main skeleton 1, which is convenient for the Y-axis tension plate 117 to drive the Y-axis tension connecting rod 116 to move; the slot of the second mounting slot 119 faces the end of the main skeleton 1, which is convenient for the Y-axis tension plate 117 to drive the Y-axis tension plate 117 to move.

[0041] In the above embodiment, as shown in Figure 4 , the tail of the main skeleton 1 is bolted with the winding machine through the flange, the tail of the main skeleton 1 is provided with a concave round hole for positioning the main skeleton 1 and the tail seat of the winding machine, and the end of the main skeleton 1 close to the flange is provided with the second limiting piece 4. The present application realizes the connection with the winding machine through the flange, the concave round hole of the tail of the main skeleton 1 is matched with the tail seat of the winding machine, further realizing the positioning and bolt connection of the tail of the main skeleton 1 and the winding machine, and ensuring the stability and firmness of the main skeleton 1 during operation. The second limiting piece 4 is arranged on the main skeleton 1, which can limit the position of the X-axis tension plate 114, avoiding the movement of the X-axis tension plate 114, so as to affect the production efficiency.

[0042] In the above embodiment, as shown in Figure 1 , the end of the main screw rod 2 is sleeved with a hollow sleeve 5. The arrangement of the hollow sleeve 5 is convenient for fixing the main screw rod 2 on other production equipment, and is convenient for further winding rectangular coils.

[0043] The embodiment of the present application also provides the application of the aforementioned bidirectional asynchronous telescopic tool for rectangular coil winding to a transformer coil. The tool can meet the winding requirements of rectangular coils of different specifications, and greatly improves the production efficiency by adjusting the bidirectional size as required.

[0044] Working principle:

[0045] The bidirectional asynchronous telescopic tool for rectangular coil winding is provided with the rotating X-axis adjusting member 221. When the X-axis adjusting member 221 moves towards the end of the main body screw 2, the X-axis tension main push connecting rod 33 is moved, and the X-axis tension plate 114 is also moved towards the end of the main body screw 2 under the joint action of the X-axis tension main push connecting rod 33 and the X-axis tension connecting rod 112. The long edge direction size of the present application is gradually reduced, and at this time, the tool is in a contraction state. When the long edge direction size is appropriate, the first limiting member 24 corresponding to the X-axis adjusting member 221 is rotated, and the first limiting member 24 is tightly attached to the X-axis adjusting member 221. At this time, the first limiting member 24 locks the X-axis adjusting member 221, and the X-axis adjusting member 221 is limited in position, so that the position of the X-axis adjusting member 221 is fixed and loosening is avoided. The X-axis adjusting member 221 is rotated in the opposite direction. At this time, the X-axis adjusting member 221 moves towards the end of the main body frame 1, and the X-axis tension main push connecting rod 33 moves towards the tail of the main body frame 1, so that the X-axis tension plate 114 also moves towards the tail of the main body frame 1. The long edge direction size of the present application is gradually increased, and at this time, the tool is in an opening state. When the X-axis tension plate 114 moves to the appropriate position, the X-axis adjusting member 221 is stopped, and then the first limiting member 24 corresponding to the X-axis adjusting member 221 is rotated, and the first limiting member 24 is tightly attached to the X-axis adjusting member 221. At this time, the first limiting member 24 locks the X-axis adjusting member 221, so that the X-axis adjusting member 221 is not loosened, the position of the X-axis adjusting member 221 is fixed, and the long edge direction size is further adjusted. The long edge direction size changes in the range of 0-45mm.

[0046] When the short side direction size is adjusted to a suitable size, the Y-axis adjusting member 231 is rotated to correspond to the first limiting member 24, until the first limiting member 24 is tightly attached to the Y-axis adjusting member 231, at which time the first limiting member 24 locks the Y-axis adjusting member 231, fixing the position of the Y-axis adjusting member 231, thereby preventing the Y-axis tensioning plate 117 from loosening. The Y-axis adjusting member 231 is rotated in the opposite direction, at which time the Y-axis adjusting member 231 moves toward the end of the main framework 1, driving the Y-axis tensioning main push link 34, and in turn driving the Y-axis tensioning plate 117 to move toward the tail of the main framework 1, at which time the short side direction size of the present application gradually increases, to an open state. When the Y-axis tensioning plate 117 is moved to a suitable position, the Y-axis adjusting member 231 is then rotated to correspond to the first limiting member 24, until the first limiting member 24 is tightly attached to the Y-axis adjusting member 231, at which time the first limiting member 24 locks the Y-axis adjusting member 231, fixing the position of the Y-axis adjusting member 231. Thus, the short side direction size is adjusted, and the short side direction size change range is 0-45mm. By rotating the X-axis adjusting member 221 and the Y-axis adjusting member 231, the X-axis tensioning main push link 33 and the Y-axis tensioning main push link 34 are driven, thereby realizing the opening and closing of the present application. By rotating the X-axis adjusting member 221 and the Y-axis adjusting member 231 respectively, the bidirectional asynchronous extension and contraction of the present application is realized. When the short side size and the long side size are adjusted to a suitable size, the concave circular hole at the tail of the main framework 1 can conveniently position the tail seat of the winding machine, further enabling the present application to quickly pass through the flange and be bolted to the winding machine, while ensuring that the main framework 1 is stable and secure during operation. The end of the main lead screw 2 is fixed to other production equipment through the hollow sleeve 5. When the position of the present application is completely fixed, the rectangular coil is then wound.

Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical thought disclosed by the present application should be covered by the claims of the present application.
