Technical Field

[0001] This application relates to the technical field of manufacturing composite insulators for power transmission and transformation, and in particular to a core mold support mechanism. Background Technology

[0002] In the current manufacturing process of composite insulators for power transmission and transformation, the insulating tube core mold is placed at the winding station, with its two ends supported by two bearing seats. The two bearing seats drive the core mold's shafts to rotate, thus completing the winding process. For shafts of different specifications, to ensure that the axis of the corresponding core mold at the winding station is coaxial with the axis of the drive shaft on the winding equipment, shims must be manually installed or removed under the bearing seats to meet the coaxiality requirement. This process is cumbersome, resulting in low winding production efficiency and low safety for manual operation. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this application is to provide a core mold support mechanism that can support core molds of different specifications, is easy to operate, can improve production efficiency, and can improve the safety of manual operation.

[0004] To achieve the above objectives, the technical means adopted in this application are as follows: A core mold support mechanism is provided for supporting a core mold, including a base plate, a support seat, and two support bodies. The support seat is fixedly connected to the base plate. The support seat is provided with a first groove and a second groove spaced apart. The two support bodies are respectively engaged in the first groove and the second groove. The axes of the two support bodies are located on the same horizontal plane. The core mold is placed on the two support bodies, and the center line between the axis of the core mold and the axis of the two support bodies is located in the same vertical plane. The support body includes a support shaft, a bearing component, and a support block. The support block is a hollow columnar body. The support block and the support shaft are connected by the bearing component, so that the support block rotates around the support shaft. The support shaft includes a connecting part and two support parts. The two support parts are respectively fixedly connected to the two end faces of the connecting part. The support parts are arranged on the end face of the connecting part near the edge of the connecting part, and the two support parts are coaxially arranged in the axial direction of the connecting part.

[0005] In one embodiment, the support base includes two first connecting plates and two second connecting plates. The two first connecting plates are parallel to each other and vertically arranged on the base plate, and the two second connecting plates are parallel to each other and vertically arranged on the base plate. The two second connecting plates respectively cover the two ends of the two first connecting plates located on the same side, and the two first connecting plates and the two second connecting plates form a rectangular cavity on the base plate.

[0006] In one embodiment, the first connecting plate and the base plate, the second connecting plate and the base plate, and the first connecting plate and the second connecting plate are all fixed by welding.

[0007] In one embodiment, a first groove and a second groove are provided at intervals along the length of the first connecting plate, and the two ends of one support are respectively engaged in the first grooves of the two first connecting plates, and the two ends of the other support are respectively engaged in the second grooves of the two first connecting plates.

[0008] In one embodiment, the first connecting plate is further provided with a third groove, which is located between the first groove and the second groove, and the third groove is an arc-shaped groove.

[0012] In one embodiment, the outer side of the support portion is located inside the outer peripheral surface of the connector portion, and the distance between the outer side and the inner side of the support portion is less than or greater than the radius of the end face of the connector portion.

[0013] In one embodiment, the outer surface of the support is an arc surface, and the inner surface of the support is a plane.

[0014] The beneficial effects of this application are as follows: Unlike the prior art, this application optimizes the support body of the core mold support mechanism by setting the support body to include a connecting part and a supporting part, with the supporting part located on the end face of the connecting part near the edge of the connecting part.

[0019] As requested, specific embodiments of this application are disclosed herein. However, it should be understood that the embodiments disclosed herein are merely typical examples of this application and may be embodied in various forms. Therefore, the specific details disclosed herein are not intended to be limiting, but merely to serve as the basis for the claims and as a representative basis for teaching those skilled in the art to apply this application differently in practice in any appropriate manner, including employing the various features disclosed herein in combination with features that may not be explicitly disclosed herein.

[0020] like Figure 1 As shown, this application provides a core mold support mechanism 100, disposed on a winding device, for supporting a core mold. The core mold is surrounded by resin-impregnated glass fiber to form a composite insulator. The core mold support mechanism 100 includes a base plate 110, a support seat 120, and two support bodies 130. The support seat 120 is fixedly connected to the base plate 110. The support seat 120 has a first groove 1211 and a second groove 1212 spaced apart. The two support bodies 130 are respectively engaged in the first groove 1211 and the second groove 1212, so that the two support bodies 130 are engaged 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 ends at both ends of the core mold are supported on the two support bodies 130. The axis of the shaft ends of the core mold is the same straight line as the axis of the core mold. The centerline between the axis of the core mold and the axis of the two support bodies 130 is located in the same vertical plane. The base plate 110 is a metal plate and is fixed on the frame of the winding equipment (not shown). Along the length of the frame, there are two core mold support mechanisms 100, which are used to support the two ends of the core mold respectively. When the core mold is placed on the core mold support mechanism 100, the axis of the core mold and the axis of the drive shaft of the frame are on the same straight line. In this way, the drive shaft can drive the core mold to rotate to realize the winding function of the core mold.

[0021] Combination Figure 2As shown, the support base 120 includes two first connecting plates 121 and two second connecting plates 122. Both the first connecting plates 121 and the second connecting plates 122 are vertically mounted on the base plate 110. The two first connecting plates 121 are arranged parallel to each other, and the two second connecting plates 122 are also arranged parallel to each other. The two second connecting plates 122 respectively cover the two ends of the two first connecting plates 121 located on the same side, thereby forming a rectangular cavity on the base plate 110. The first connecting plates 121 and the base plate 110, the second connecting plates 122 and the base plate 110, and the first connecting plates 121 and the second connecting plates 122 are all fixed together by welding.

[0022] Along the length of the first connecting plate 121, first grooves 1211 and second grooves 1212 are provided at intervals on the first connecting plate 121. The center line of the first grooves 1211 on the two first connecting plates 121 is parallel to the length direction of the second connecting plate 122, and the center line of the second grooves 1212 on the two first connecting plates 121 is parallel to the length direction of the second connecting plate 122. Thus, spaces for placing supports 130 are formed between the two first grooves 1211 and between the two second grooves 1212. The two ends of one support 130 are respectively engaged in the first grooves 1211 of the two first connecting plates 121, and the two ends of the other support 130 are respectively engaged in the second grooves 1212 of the two first connecting plates 121. 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 supports 130 are located on the same horizontal plane, and the center line between the axis of the core mold placed on the two supports 130 and the axis of the two supports 130 is located in the same vertical plane, so that the core mold is kept in balance.

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

[0024] Continue reading Figure 2 The first connecting plate 121 is also provided with a third groove 1213, which is located between the first groove 1211 and the second groove 1212. The third groove 1213 is an arc-shaped groove. When the shaft head of the core mold is placed between the two supports 130, the outer peripheral surface of the bottommost part of the shaft head of the core mold can be locked in the third groove 1213 to avoid interference between the shaft head of the core mold and the first connecting plate 121.

[0025] Combination Figure 3As shown, the support body 130 includes a support shaft 131, a bearing 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 132, allowing the support block 133 to rotate around the support shaft 131. This is because the mandrel's shaft head is directly placed on the support block 133, and the mandrel needs to rotate around its axis to achieve the winding function. Therefore, the support block 133 is designed to also rotate to reduce the frictional force generated when the mandrel contacts the support block 133 during rotation, thereby improving winding efficiency and preventing damage to the mandrel. The support shaft 131 includes a connecting portion 1311 and two support portions 1312. The connecting portion 1311 is a columnar body and includes two end faces arranged opposite each other 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 engaged in the first groove 1211 or the second groove 1212, so that the support body 130 is engaged and fixed on the support base 120. The outer peripheral dimensions of the support portion 1312 correspond to and match the dimensions of the first groove 1211 and the second groove 1212 to prevent the support portion 1312 from shifting in the first groove 1211 or the second groove 1212 when the support block 133 rotates, thereby 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 arranged radially opposite to each other along 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 base 120, so that the support body 130 is engaged on the support base 120. Here, the outer side surface 13121 of the support portion 1312 refers to the side of the support portion 1312 near the outer peripheral surface of the connecting portion 1311, and the inner side surface of the support portion 1312 is the other side arranged opposite to the outer side surface 13121.

[0027] In this embodiment, the support portion 1312 is disposed on one side edge of the end face of the connecting portion 1311 near the connecting portion 1311, and the two support portions 1312 are coaxially disposed in the axial direction of the connecting portion 1311. In one embodiment, the outer surface 13121 of the support portion 1312 is flush with the outer peripheral surface 13111 of the connecting portion 1311, and the inner surface 13122 of the support portion 1312 is flush with the axis of the connecting portion 1311, that is, the axis of the connecting portion 1311 is located on the inner surface 13122 of the support portion 1312. At this time, the distance between the outer surface 13121 and the inner surface 13122 of the support portion 1312 is equal to the radius of the end face of the connecting portion 1311. In other embodiments, a certain distance may be provided between the outer side of the support portion and the outer peripheral surface of the connecting portion, that is, the outer side of the support portion is located inside the outer peripheral surface of the connecting portion 1311; or the inner side of the support portion may not be flush with the axis of the connecting portion 1311, so that the distance between the outer side and the inner side of the support portion is less than or greater than the radius of the end face of the connecting portion 1311, depending on the design of the shaft head size of the core mold, as long as it does not affect the rotation.

[0028] In one embodiment, the outer surface 13121 of the support portion 1312 is an arc surface, and the arc diameter of the outer surface 13121 of the support portion 1312 is equal to the diameter of the outer peripheral surface of the connecting portion 1311. Thus, the outer surface of the support portion 1312 and the outer peripheral surface of the connecting portion 1311 are located within the same arc surface. Meanwhile, the inner surface 13122 of the support portion 1312 is a plane. In other embodiments, the outer surface 13121 of the support portion 1312 may also be a plane, and the inner surface 13122 of the support portion 1312 may also be an arc surface; no limitation is imposed here.

[0029] Combination Figure 4As shown, for ease of explanation, in this embodiment, the outer surface 13121 of the support portion 1312 is flush with the outer peripheral surface 13111 of the connecting portion 1311, and the inner surface 13122 of the support portion 1312 is flush with the axis of the connecting portion 1311. In the initial state, the core mold support mechanism 100 supports the first core mold. Specifically, the first core mold has first shaft heads A1 protruding from both ends. The first shaft heads A1 are supported on the two support bodies 130, and the outer diameter of the first shaft head A1 is D1. At this time, the inner surface 13122 of the support part 1312 abuts against the first groove 1211 or the second groove 1212, so that the support body 130 is engaged on the support base 120 through the support parts 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 surface 13122 of the support part 1312. Then, the axes of the two support bodies 130 are located on the same horizontal plane, and the axes of the support bodies 130 are 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 and the axis of the drive shaft of the winding device are located on the same horizontal plane L2, that is, the first shaft head A1 and the drive shaft are coaxially arranged. Then, the drive shaft drives the first shaft head A1 to rotate, so that the first mandrel realizes the winding function.

[0030] After the first mandrel completes the winding process, it needs to be replaced with a second mandrel according to production requirements. The second mandrel has two protruding ends with second shaft heads B1, and the outer diameter of the second shaft head B1 is D2, where D2 is smaller than D1. If the mandrel support mechanism 100 remains in the same position as when supporting the first mandrel, the axis of the second shaft head B1 will be below the horizontal plane L2. This means the second mandrel cannot be coaxial with the drive shaft of the winding equipment, and consequently, the winding equipment will be unable to drive the second mandrel to perform the winding process along the preset trajectory. In the traditional method, to increase the horizontal height of the second shaft head B1, a pad of a certain thickness is placed under the base 110 of the mandrel support mechanism 100. The thickness of the pad is equal to the difference between D2 and D1, so that the axis of the second shaft head B1 and the axis of the drive shaft of the winding equipment are both located within the horizontal plane L2. This method is cumbersome and has low production efficiency. In this application, in order to make the second shaft head B1 of the second core mold coaxial with the drive shaft of the winding device, it is only necessary to change the position of the support body 130 so that its outer side 13121 abuts against the first groove 1211 or the second groove 1212, and then the support body 130 is locked onto the support seat 120 through the support parts 1312 at both ends. At this time, the axis of the support body 130 is located in the horizontal plane L3. Since the support part 1312 is set on the end face of the connecting part 1311 near the edge of the connecting part 1311, after the support surface of the support body 130 is changed 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 located in the horizontal plane L2, thereby making the axis of the second shaft head B1 coaxial with the transmission shaft.

[0031] In other embodiments, the second core mold can be replaced with the first core mold, and the principle is as described above, so it will not be repeated here.

[0032] Furthermore, in other embodiments, the distance between the outer and inner sides of the support can be designed according to specific circumstances, as long as it can accommodate the switching between the shaft ends of the two types of mandrels. Of course, in other embodiments, the coaxiality of the mandrel shaft and the drive shaft can also be achieved by directly replacing the support body with one of different sizes, which expands the applicability of the mandrel support mechanism and further improves production efficiency.

[0033] The beneficial effects of this application are as follows: Unlike the prior art, this application optimizes the support body of the core mold support mechanism by setting the support body to include a connecting part and a supporting part, with the supporting part located on the end face of the connecting part near the edge of the connecting part. Then, the supporting body abuts against the groove of the support seat through different sides of the supporting part, so as to raise or lower the axis of the supporting body, so that the shaft head of the core mold is coaxially set with the drive shaft of the winding equipment. That is, the core mold support mechanism of this application can be used to support core molds of various specifications, is easy to operate, improves production efficiency, and improves the safety of manual operation.

[0034] The technical content and features of this application have been disclosed above. However, it is understood that, based on the inventive concept of this application, those skilled in the art can make various changes and improvements to the above-described structure and materials, including combinations of the technical features disclosed or claimed herein, and explicitly including other combinations of these features. All such modifications and / or combinations fall within the technical field to which this application pertains and are within the scope of protection of the claims of this application.
