[0019] According to the requirements, the detailed implementation manners of the present application will be disclosed here. However, it should be understood that the implementation manners disclosed here are only typical examples of the present application, which can be embodied in various forms. Therefore, the specific details disclosed here are not considered restrictive, but only as the basis for the claims and as the basis for teaching those skilled in the art to apply the present application differently in any appropriate manner in practice, including adopting various features disclosed here and combining features that may not be explicitly disclosed here.

[0020] As Figure 1 shown, the present application provides a core mold support mechanism 100, which is arranged on a winding device and used to support a core mold. A composite insulator is formed by winding glass fibers impregnated with resin outside the core mold. The core mold support mechanism 100 includes a bottom plate 110, a support seat 120, and two support bodies 130. The support seat 120 is fixedly connected to the bottom plate 110. The support seat 120 is provided with a first groove 1211 and a second groove 1212 that are spaced apart. The two support bodies 130 are respectively clamped in the first groove 1211 and the second groove 1212, so that the two support bodies 130 are clamped on the support seat 120. The axes of the two support bodies 130 are located on the same horizontal plane. The core mold is placed on the two support bodies 130. Specifically, the shaft heads at both ends of the core mold are supported on the two support bodies 130. The axis of the shaft head of the core mold and the axis of the core mold are the same straight line. The midline between the axis of the core mold and the axes of the two support bodies 130 is located in the same vertical plane. Among them, the bottom plate 110 is a metal plate member, and the bottom plate 110 is fixed on the frame of the winding device (not shown in the figure). In the length direction of the frame, two core mold support mechanisms 100 are arranged at intervals, respectively used to support both ends of the core mold. When the core mold is placed on the core mold support mechanism 100, the axis of the core mold and the axis of the transmission shaft of the frame are located on the same straight line. In this way, the transmission shaft can drive the core mold to rotate to realize the winding function of the core mold.

[0021] Combined with Figure 2As shown, the support base 120 includes two first connecting plates 121 and two second connecting plates 122. The two first connecting plates 121 and the two second connecting plates 122 are both vertically arranged on the bottom plate 110. The two first connecting plates 121 are arranged in parallel with each other, and the two second connecting plates 122 are arranged in parallel with each other. The two second connecting plates 122 respectively cover the two ends of the two first connecting plates 121 on the same side. Then, the two first connecting plates 121 and the two second connecting plates 122 enclose a rectangular cavity on the bottom plate 110. Among them, the first connecting plate 121 and the bottom plate 110, the second connecting plate 122 and the bottom plate 110, and the first connecting plate 121 and the second connecting plate 122 are all fixed by welding.

[0022] In the length direction of the first connecting plate 121, a first groove 1211 and a second groove 1212 are arranged at intervals on the first connecting plate 121. The midlines of the first grooves 1211 on the two first connecting plates 121 are parallel to the length direction of the second connecting plate 122, and the midlines of the second grooves 1212 on the two first connecting plates 121 are parallel to the length direction of the second connecting plate 122. Then, spaces for placing the support bodies 130 are formed between the two first grooves 1211 and between the two second grooves 1212. The two ends of one support body 130 are respectively clamped in the first grooves 1211 of the two first connecting plates 121, and the two ends of the other support body 130 are respectively clamped in the second grooves 1212 of the two first connecting plates 121. Among them, the depth of the first groove 1211 is the same as the depth of the second groove 1212, so that the axes of the two support bodies 130 are located on the same horizontal plane. Then, the axis of the core mold placed on the two support bodies 130 and the midline between the axes of the two support bodies 130 are located in the same vertical plane, so that the core mold is kept balanced.

[0023] In one embodiment, both the first groove 1211 and the second groove 1212 are rectangular grooves. In other embodiments, the first groove and the second groove can also be arc grooves or grooves of other shapes.

[0024] Continue to refer to Figure 2 , a third groove 1213 is further provided on the first connecting plate 121. The third groove 1213 is located between the first groove 1211 and the second groove 1212. The third groove 1213 is an arc groove. When the shaft head of the core mold is placed between the two support bodies 130, the outer peripheral surface at the lowest position of the shaft head of the core mold can be clamped in the third groove 1213, so as to avoid interference between the shaft head of the core mold and the first connecting plate 121.

[0025] Combined with Figure 3As shown in the figure, the support body 130 includes a support shaft 131, a bearing member 132, and a support block 133. The support block 133 is a hollow columnar body. The support block 133 and the support shaft 131 are connected by the bearing member 132, enabling the support block 133 to rotate around the support shaft 131. This is because the shaft head of the core mold is directly placed on the support block 133, and the core mold needs to rotate around its axis to achieve the winding function. Therefore, the support block 133 is also set to be rotatable to reduce the friction generated when the core mold contacts the support block 133 during rotation, improve the winding efficiency, and avoid damage to the core mold. The support shaft 131 includes a connecting portion 1311 and two support portions 1312. The connecting portion 1311 is a columnar body. The connecting portion 1311 includes two end faces oppositely arranged along its axial direction. The two support portions 1312 are respectively fixedly connected to the two end faces of the connecting portion 1311. The two support portions 1312 are clamped in the first groove 1211 or the second groove 1212, so that the support body 130 is clamped and fixed on the support seat 120. Among them, the outer peripheral dimension of the support portion 1312 corresponds to and matches the dimensions of the first groove 1211 and the second groove 1212, preventing the support portion 1312 from shifting in the first groove 1211 or the second groove 1212 when the support block 133 rotates, thus affecting the support stability of the core mold.

[0026] Specifically, the support portion 1312 includes an outer side surface 13121 and an inner side surface 13122 oppositely arranged along the radial direction of the support body 130. The outer side surface 13121 or the inner side surface 13122 of the support portion 1312 abuts against the first groove 1211 or the second groove 1212 of the support seat 120, so that the support body 130 is clamped on the support seat 120. Among them, the outer side surface 13121 of the support portion 1312 refers to the side surface of the support portion 1312 close to the outer peripheral surface of the connecting portion 1311, and the inner side surface of the support portion 1312 is the other side surface oppositely arranged with the outer side surface 13121.

[0027] Among them, the supporting part 1312 is arranged on the end surface of the connecting part 1311 near one side edge of the connecting part 1311, and the two supporting parts 1312 are coaxially arranged in the axial direction of the connecting part 1311. In an embodiment, the outer side surface 13121 of the supporting part 1312 is flush with the outer peripheral surface 13111 of the connecting part 1311, and the inner side surface 13122 of the supporting part 1312 is flush with the axis of the connecting part 1311, that is, the axis of the connecting part 1311 is located on the inner side surface 13122 of the supporting part 1312. At this time, the distance between the outer side surface 13121 and the inner side surface 13122 of the supporting part 1312 is equal to the radius of the end surface of the connecting part 1311. In other embodiments, a certain distance can also be set between the outer side surface of the supporting part and the outer peripheral surface of the connecting part, that is, the outer side surface of the supporting part is located inside the outer peripheral surface of the connecting part 1311; or the inner side surface of the supporting part can also be not flush with the axis of the connecting part 1311, so that the distance between the outer side surface and the inner side surface of the supporting part is less than or greater than the radius of the end surface of the connecting part 1311, which is specifically designed according to the shaft head size of the core mold as long as the rotation is not affected.

[0028] In an embodiment, the outer side surface 13121 of the supporting part 1312 is an arc surface, and the arc diameter of the outer side surface 13121 of the supporting part 1312 is equal to the diameter of the outer peripheral surface of the connecting part 1311. In this way, the outer side surface of the supporting part 1312 and the outer peripheral surface of the connecting part 1311 are located in the same arc surface. At the same time, the inner side surface 13122 of the supporting part 1312 is a plane. In other embodiments, the outer side surface 13121 of the supporting part 1312 can also be a plane, and the inner side surface 13122 of the supporting part 1312 can also be an arc surface, which is not limited here.

[0029] Combined with Figure 4As shown, for the convenience of description, in this embodiment, the outer side surface 13121 of the support portion 1312 is flush with the outer peripheral surface 13111 of the connection portion 1311, and the inner side surface 13122 of the support portion 1312 is flush with the axis of the connection portion 1311. In the initial state, the first core mold is supported on the core mold support mechanism 100. Specifically, first shaft heads A1 protrude from both ends of the first core mold, and the first shaft heads A1 are supported on two support bodies 130, and the outer diameter of the first shaft heads A1 is D1. At this time, the inner side surface 13122 of the support portion 1312 abuts against the first groove 1211 or the second groove 1212, so that the support body 130 is clamped on the support seat 120 through the support portions 1312 at both ends, and both support bodies 130 abut against the bottom surface of the first groove 1211 or the second groove 1212 through the inner side surface 13122 of the support portion 1312. Subsequently, the axes of the two support bodies 130 are located on the same horizontal plane, and the axis of the support body 130 is located in the horizontal plane L1. The first shaft head A1 is placed in the middle of the two support bodies 130. At this time, the axis of the first shaft head A1 is located on the same horizontal plane L2 as the axis of the transmission shaft of the winding device, that is, the first shaft head A1 is coaxially arranged with the transmission shaft. Subsequently, the transmission shaft drives the first shaft head A1 to rotate, so that the first core mold realizes the winding function.

[0030] After the first core mold completes the winding process, according to production requirements, the first core mold needs to be replaced with the second core mold. The second shaft heads B1 protrude from both ends of the second core mold, and the outer diameter of the second shaft head B1 is D2, where D2 is less than D1. At this time, if the core mold support mechanism 100 maintains the state when supporting the first core mold, then the axis of the second shaft head B1 will be below the horizontal plane L2, that is, the second core mold cannot be coaxial with the transmission shaft of the winding equipment, and then the winding equipment will also be unable to drive the second core mold to perform the winding process according to the preset trajectory. In the traditional method, in order to increase the horizontal height of the second shaft head B1, a cushion plate with a certain thickness is set under the base 110 of the core mold support mechanism 100, and the thickness of the cushion plate is set to be equal to the difference between D2 and D1, so as to make the axes of the second shaft head B1 and the transmission shaft of the winding equipment both lie in the horizontal plane L2. The operation is cumbersome and the production efficiency is low. In this application, in order to make the second shaft head B1 of the second core mold coaxial with the transmission shaft of the winding equipment, only need to swap the position of the support body 130 so that its outer side surface 13121 abuts against the first groove 1211 or the second groove 1212, and then the support body 130 is clamped on the support seat 120 through the support parts 1312 at both ends. At this time, the axis of the support body 130 lies in the horizontal plane L3, and since the support parts 1312 are arranged on one side edge close to the connecting part 1311 on the end surface of the connecting part 1311, after changing the support surface of the support body 130 from the inner side surface 13122 to the outer side surface 13121, the horizontal plane L3 is higher than the horizontal plane L1, that is, the axis of the support body 130 is raised. Then, when the second shaft head B1 of the second core mold is supported on the two support bodies 130, the axis of the second shaft head B1 is also raised. By designing the distance between the outer side surface 13121 and the inner side surface 13122 of the support part 1312, the axis of the second shaft head B1 can be made to lie in the horizontal plane L2, and then the axis of the second shaft head B1 can be made coaxial with the transmission shaft.

[0031] In other embodiments, it may also be changing from the second core mold to the first core mold. The principle is as described above and will not be elaborated here.

[0032] Moreover, in other embodiments, the distance between the outer side surface and the inner side surface of the support part can also be designed according to specific circumstances, as long as it can meet the switching of the shaft heads of the two specifications of core molds. Of course, in other embodiments, it is also possible to directly replace the support body with different sizes to make the shaft head of the core mold coaxial with the transmission shaft, which can expand the applicable range of the core mold support mechanism and further improve the production efficiency.

[0033] The beneficial effects of the present application are as follows: Different from the prior art, in the present application, the support body of the core mold support mechanism is optimized. The support body is set to include a connecting portion and a supporting portion, and the supporting portion is arranged on one side edge close to the connecting portion on the end surface of the connecting portion. Then, the support body is abutted against the groove of the support seat through different side surfaces of the supporting portion to realize the elevation or reduction of the axis of the support body, so that the shaft head of the core mold is coaxially arranged with the transmission shaft of the winding equipment. That is, the core mold support mechanism of the present application can be applicable to supporting core molds of various different specifications, is convenient to operate, improves production efficiency, and improves the safety of manual operation.

[0034] The technical content and technical features of the present application have been disclosed above. However, it can be understood that under the creative concept of the present application, those skilled in the art can make various changes and improvements to the above structures and materials, including combinations of the technical features separately disclosed or claimed here, and obviously other combinations of these features. These deformations and / or combinations all fall within the technical field involved in the present application and within the protection scope of the claims of the present application.
