Description

Technical Field

[0001] This invention relates to the field of power equipment, and more specifically to a manufacturing apparatus for a drop-out fuse. Background Technology

[0002] The porcelain insulators of existing drop-out fuses, as shown in the attached... Figure 1 As shown, the porcelain vase is fixed with three fittings: an upper fitting at the top, a lower fitting at the bottom, and a middle fitting in the middle area. The upper fitting extends outward along the axial direction of the vase and then bends horizontally; the lower fitting extends outward along the axial direction and then bends horizontally; and the middle fitting extends outward along the radial direction. The upper fittings, lower fittings, and middle fittings of each vase must be on the same plane.

[0003] In the prior art, the method of fixing the conductive component to the porcelain insulator usually involves using cement (such as quick-setting cement (which can be double-fast cement)) for adhesive bonding.

[0004] Appendix Figures 1-2 The porcelain vase requires three gluing points. In a normal gluing process, each gluing point needs to be positioned, cement poured, and allowed to solidify before being repositioned, cement poured again, and allowed to solidify once more, finally completing the final gluing point. Furthermore, after each pour, the vase's end position may change, requiring adjustments to the positioning structure to accommodate the other end. This casting method presents several problems: 1. Pouring accuracy is reduced due to the need for multiple adjustments to the positioning structure during casting; 2. The operation is cumbersome, requiring adjustments to the positioning structure for different casting steps, demanding a certain level of skill; 3. Processing efficiency is low due to the need for multiple adjustments to the positioning structure. Summary of the Invention

[0005] Therefore, the technical problem to be solved by this invention is how to solve the problem of adhesive bonding of porcelain bottles. To this end, a manufacturing apparatus for a drop-out fuse is provided, used for processing porcelain bottles, wherein both ends of the porcelain bottle are respectively connected to an upper fixing plate and a lower fixing plate, and the porcelain bottle is provided with a first fixing cavity, a second fixing cavity, and a third fixing cavity; it includes: Base; A bracket that rotates relative to the base, the bracket including a frame-shaped part and a transverse part connected to the frame-shaped part, the frame-shaped part including an upper fixing plate and a lower fixing plate, the upper fixing plate and the lower fixing plate being arranged vertically parallel; The upper fitting has one end connected to the upper fixing plate and the other end extending into the first fixing cavity; The lower fitting has one end connected to the lower fixing plate and the other end extending into the second fixing cavity; An intermediate fitting, one end of which is connected to the transverse section, and the other end of which extends into the third fixing cavity; A deceleration mechanism is connected to the support. An external force is applied to the deceleration mechanism, which drives the support to rotate circumferentially. The support drives the porcelain bottle to rotate to the corresponding position for pouring. The deceleration mechanism is provided with a structure to limit reverse rotation.

[0006] The upper fixing plate is fixed with a first elastic pressure plate, which applies pressure to the upper hardware so that the upper hardware is located between the first elastic pressure plate and the upper fixing plate; the lower fixing plate is fixed with a second elastic pressure plate, which applies pressure to the lower hardware so that the lower hardware is located between the second elastic pressure plate and the lower fixing plate.

[0007] It also includes two third elastic pressure plates, which are respectively connected to the upper fixing plate and the lower fixing plate, and apply pressure to the side of the porcelain bottle.

One of the bottom surface of the second positioning groove and the lower fitting is provided with a second positioning protrusion, and the other of the bottom surface of the second positioning groove and the lower fitting is provided with a second positioning hole that mates with the second positioning protrusion. The transverse plate is provided with a third positioning groove, and the intermediate fitting extends into the third positioning groove.

[0009] It also includes a manual locking component, which includes an operating head and a screw portion. The operating head has a gripping structure for direct hand gripping and applying rotational force. The screw portion is connected to the lower end of the operating head. The outer peripheral wall of the screw portion is provided with external threads. The screw portion passes through the intermediate hardware and is connected to the transverse platen portion.

[0010] The upper fixing plate has a first notch, the lower fixing plate has a second notch, the second notch has a positioning part, the lower end of the porcelain bottle abuts against the positioning part, and the upper end of the porcelain bottle passes through the first notch.

[0011] When pouring the first and second fixed cavities, the central axis of the porcelain bottle forms an angle with the height direction of the base, the angle being greater than or equal to 0° and less than or equal to 45°.

[0012] It also includes a handle, which is connected to the deceleration mechanism. An external force drives the handle to rotate, and the handle drives the deceleration mechanism to move.

[0013] The reduction mechanism includes a worm gear reducer.

[0014] The bracket has rotating shafts at both ends, and the base has two support columns. Each of the two support columns is fixed with a bearing. One of the rotating shafts passes through the bearing and is connected to the reduction mechanism, while the other rotating shaft passes through the other bearing.

[0015] The technical solution of this invention has the following advantages: 1. This invention provides a manufacturing apparatus for drop-out fuses. This apparatus, consisting of a base, a support, and a reduction mechanism, forms a simplified device. It secures the porcelain insulator to the upper, lower, and intermediate fittings. During pouring, the reduction mechanism's reversing structure positions and fixes the support. After pouring, the cement sets before pouring at the next location, allowing for pouring at three different locations to achieve the desired processing effect. This structure is simple, easy to operate, and allows one support to fix several porcelain insulators, enabling batch and standardized pouring. Once fixed, no repositioning is needed; the reduction mechanism rotates the support to adjust to the next location. Most importantly, the overall structure is simple, with low manufacturing costs, allowing for large-scale assembly and increased pouring efficiency through increased quantity.

[0016] 2. The manufacturing apparatus for a drop-out fuse provided by the present invention adopts an elastic pressure plate, which makes it more convenient to install and fix the conductive parts.

[0017] 3. The manufacturing apparatus for a drop-out fuse provided by the present invention achieves the installation and fixation of the porcelain insulator through two third elastic pressure plates, so that the porcelain insulator will not fall off during the casting process, and the positioning and fixing effect of the porcelain insulator is achieved.

[0018] 4. The present invention provides a manufacturing apparatus for a drop-out fuse. The positioning groove is set to achieve the effect of positioning and fixing, so that the conductive component is accurately positioned and the positional relationship (coaxiality, extension into the fixed cavity, etc.) between the conductive component and the corresponding fixed cavity is realized.

[0019] 5. The present invention provides a manufacturing apparatus for a drop-out fuse, which achieves connection and fixation between the intermediate hardware and the transverse section through a manual locking component, thereby improving the assembly accuracy of the intermediate hardware. Here, the manual locking component allows for tool-free installation and fixation, which is simpler than tool-operated methods and achieves the effect of tool-free operation.

[0020] 6. The present invention provides a manufacturing apparatus for a drop-out fuse. During the casting process, the support is tilted, and the porcelain insulator is also tilted.

Furthermore, the rotation effect can be precisely adjusted by setting a reduction gear. Alternatively, it can be driven by a motor to achieve a semi-automatic control effect.

[0022] 8. The present invention provides a manufacturing apparatus for a drop-out fuse. During the rotation of the worm gear reducer, when the helix angle (lead angle) of the worm is less than the friction angle, the friction between the two will prevent reverse rotation. When you release the handle, even if the bracket is hanging a heavy object or there is a reverse torque, it cannot drive the worm in reverse, and the bracket will be firmly fixed in place.

[0023] 9. The manufacturing apparatus for a drop-out fuse provided by the present invention, wherein the setting of the support column better achieves support and fixation, making the rotation of the rotating shaft more stable. Attached Figure Description

[0030] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] Example 1 This embodiment provides a manufacturing apparatus for a drop-out fuse, as shown in the attached diagram. Figures 1-9 As shown, this processing device is specifically used to process porcelain bottles. Before processing, the porcelain bottle 13 is not cast with the upper fitting 14, lower fitting 15, and intermediate fitting 16; it is a single component. The two ends of the porcelain bottle 13 are connected to the upper fixing plate 123 and the lower fixing plate 124, respectively. The upper end of the porcelain bottle 13 is connected and fixed to the upper fixing plate 123, and the lower end of the porcelain bottle 13 is connected and fixed to the lower fixing plate 124, forming a connection and fixation between the porcelain bottle 13 and the entire support 12. The porcelain bottle 13 has a first fixing cavity 131, a second fixing cavity 132, and a third fixing cavity 133. Here, the first fixing cavity 131 is located at the upper end of the porcelain bottle 13, that is, at the top surface of the porcelain bottle 13; the second fixing cavity 132 is located at the lower end of the porcelain bottle 13, that is, at the bottom surface of the porcelain bottle 13; and the third fixing cavity 133 is located on the side of the porcelain bottle 13. In this embodiment, the third fixing cavity 133 is located in the central area of ​​the side of the porcelain bottle 13. In this embodiment, the dimensions (e.g., inner diameter, depth, etc.) of the first fixing cavity 131, the second fixing cavity 132, and the third fixing cavity 133 can be adjusted according to actual needs.

[0032] The processing equipment includes: Base 11 is fixed to the ground, serving as a support and fixation element.

[0033] The support 12 rotates relative to the base 11. In this embodiment, the length direction of the support 12 is taken as the Y-axis, and the height direction of the support 12 is taken as the Z-axis. The support 12 rotates around the Y-axis, thus rotating relative to the base 11. The support 12 includes a frame-shaped portion 121 and a transverse section 122 connected to the frame-shaped portion 121. As the name suggests, the frame-shaped portion 121 is a frame structure. Both ends of the frame-shaped portion 121 are connected to the base 11, creating a relative rotation effect. In this embodiment, the base 11 is fixed, and the frame-shaped portion 121 is rotatable. The transverse section 122 extends obliquely outward and is a U-shaped structure with a horizontal opening. Its side is a long strip structure and is parallel to the length direction of the frame-shaped portion 121. Specifically, the long strip structure of the frame-shaped portion 121 is parallel to the upper and lower fixed plates. However, it should be noted that the transverse section 122 and the frame-shaped portion 121 are not located on the same plane.

[0034] The frame-shaped portion 121 includes an upper fixing plate 123 and a lower fixing plate 124, which are arranged parallel to each other vertically. In this embodiment, the upper fixing plate 123 is located above the lower fixing plate 124.

[0035] The upper fitting 14 is connected at one end to the upper fixing plate 123 and at the other end to the first fixing cavity 131. In this embodiment, the upper fitting 14 is made of conductive metal and has an L-shaped structure. The horizontal part of the upper fitting 14 is connected and fixed to the upper fixing plate 123, and the vertical part of the upper fitting 14 extends into the first fixing cavity 131 along the Z-axis. The length of the upper fitting 14 extending into the first fixing cavity 131 can be adjusted according to actual needs. There is a gap between the end of the upper fitting 14 and the bottom surface of the first fixing cavity 131.

[0036] The lower fitting 15 has one end connected to the lower fixing plate 124 and the other end extending into the second fixing cavity 132. The structure of the lower fitting 15 is the same as that of the upper fitting 14. In this embodiment, the lower fitting 15 is also made of conductive metal and has an L-shaped structure. The horizontal part of the lower fitting 15 is connected to the lower fixing plate 124, and the vertical part of the lower fitting 15 extends into the second fixing cavity 132 along the Z-axis. The length of the lower fitting 15 extending into the second fixing cavity 132 can be adjusted according to actual needs. There is a gap between the end of the lower fitting 15 and the bottom surface of the second fixing cavity 132.

[0037] An intermediate fitting 16 is provided, with one end connected to the transverse section 122 and the other end extending into the third fixing cavity 133. In this embodiment, the intermediate fitting 16 has a bent structure, with one end connected and fixed to the transverse section 122 and the other end extending into the third fixing cavity 133. The length of the intermediate fitting 16 extending into the third fixing cavity 133 can be adjusted according to actual needs, and a gap is provided between the end of the intermediate fitting 16 and the bottom surface of the third fixing cavity 133.

[0038] Furthermore, it should be noted that after positioning and fixing, the central axis of the portion of the upper fitting 14 extending into the first fixing cavity 131 is approximately coaxial with the central axis of the first fixing cavity 131. Although precise positioning is achieved here, positive and negative tolerances still exist, and it cannot be guaranteed that the two central axes are coaxial. Similarly, the central axis of the portion of the lower fitting 15 extending into the second fixing cavity 132 is approximately coaxial with the central axis of the second fixing cavity 132; the central axis of the portion of the middle fitting 16 extending into the third fixing cavity 133 is approximately coaxial with the central axis of the third fixing cavity 133.

[0039] The deceleration mechanism is connected to the support 12. When an external force is applied to the deceleration mechanism, it drives the support 12 to rotate circumferentially. The support 12 then drives the porcelain insulator 13 to rotate to the corresponding position for pouring. This external force can be manually driven, driven by a motor, or by other driving methods. The deceleration mechanism is equipped with a reverse-rotation limiting structure. When the external force applied to the deceleration mechanism disappears, the support 12 and the porcelain insulator 13 fixed to the support 12 will not reverse under the action of gravity.

[0040] Furthermore, the number of porcelain bottles 13 can be adjusted according to actual needs. Several porcelain bottles 13 are arranged in a single row with equal spacing, with one porcelain bottle 13 corresponding to one upper fitting 14, one lower fitting 15, and one intermediate fitting 16. Using this structure, a simplified device is formed through the base 11, support 12, and reduction mechanism, securing the porcelain bottles 13 to the upper fitting 14, lower fitting 15, and intermediate fitting 16. During pouring, the reduction mechanism's limiting and reversing structure positions and fixes the support 12. After pouring, wait for the cement to set before pouring at the next location, thus achieving pouring at three different locations and ultimately achieving the desired processing effect. This structure is simple, easy to operate, and one support 12 can fix several porcelain bottles 13, enabling batch and standardized pouring. Once fixed, there is no need for repeated positioning; the reduction mechanism rotates the support 12 to adjust to the next position. Most importantly, the overall structure is simple, with low manufacturing costs, allowing for large-scale assembly and increasing pouring efficiency through quantity.

[0041] Specifically, as shown in the attached document Figures 1-9 As shown, a first elastic pressure plate 17 is fixed to the upper fixed plate 123. One end of the first elastic pressure plate 17 is fixed to the upper fixed plate 123, and the other end is movable. The first elastic pressure plate 17 applies pressure to the upper fitting 14, so that the upper fitting 14 is located between the first elastic pressure plate 17 and the upper fixed plate 123. At this time, the upper fitting 14 forms a fixed effect, providing a positioning effect for subsequent pouring. A second elastic pressure plate 18 is fixed to the lower fixed plate 124. One end of the second elastic pressure plate 18 is fixed to the lower fixed plate 124, and the other end is movable. The second elastic pressure plate 18 applies pressure to the lower fitting 15, so that the lower fitting 15 is located between the second elastic pressure plate 18 and the lower fixed plate 124. At this time, the lower fitting 15 forms a fixed effect, providing a positioning effect for subsequent pouring. The use of elastic pressure plates makes the installation and fixing of conductive components more convenient. Furthermore, the first elastic pressure plate 17 and the second elastic pressure plate 18 have the same structure. In addition, other fixing methods, such as bolt fastening, can be used to fix the conductive parts in place.

[0042] Specifically, it also includes two third elastic pressure plates 19. These two third elastic pressure plates 19 are connected to the upper fixing plate 123 and the lower fixing plate 124, respectively. The two third elastic pressure plates 19 are connected to the side of the upper fixing plate 123 and the side of the lower fixing plate 124, respectively. The third elastic pressure plates 19 apply pressure to the side of the porcelain bottle 13. The installation and fixation of the porcelain bottle 13 are achieved through the two third elastic pressure plates 19, preventing the porcelain bottle 13 from falling off during the pouring process and achieving the positioning and fixing effect of the porcelain bottle 13.

[0043] Specifically, as shown in the attached document Figures 3-9 As shown, the first elastic pressure plate 17, the second elastic pressure plate 18, and the third elastic pressure plate 19 have the same structure. Taking the first elastic pressure plate 17 as an example, it includes a first arc-shaped portion 171 and a second arc-shaped portion 172. The connection between the first arc-shaped portion 171 and the second arc-shaped portion 172 forms a pressing area 173. The end of the first arc-shaped portion 171 away from the second arc-shaped portion 172 is connected to the upper fixing plate 123. The second arc-shaped portion 172 is a movable end. The pressing area 173 abuts against the upper hardware 14, thus forming an elastic pressing and fixing effect.

[0044] Specifically, the first elastic pressure plate 17 is located on the top surface of the upper fixed plate 123, and the second elastic pressure plate 18 is located on the top surface of the lower fixed plate 124.

[0045] Specifically, in this embodiment, one porcelain bottle 13 requires one first elastic pressure plate 17, one second elastic pressure plate 18, and two third elastic pressure plates 19.

[0046] Specifically, this is as attached Figures 3-9As shown in the embodiment, the connection ends of the first elastic pressure plate 17 and the upper fixed plate 123, the second elastic pressure plate 18 and the lower fixed plate 124, and the two third elastic pressure plates 19 and the connection ends of the upper fixed plate 123 and the lower fixed plate 124, respectively, are all fixed with bolts, and the elastic pressure applied by the elastic pressure plates can be adjusted by the bolts.

[0047] Specifically, as shown in the attached document Figures 3-9 As shown, the upper fixing plate 123 is provided with a first positioning groove 1231, and the upper fitting 14 extends into the first positioning groove 1231. One of the bottom surfaces of the first positioning groove 1231 and the upper fitting 14 is provided with a first positioning protrusion 20, and the other of the bottom surface of the first positioning groove 1231 and the upper fitting 14 is provided with a first positioning hole 21 that mates with the first positioning protrusion 20. The first positioning groove 1231 achieves the positioning and fixing of the upper fitting 14, and the first positioning protrusion 20 mates with the first positioning hole 21, forming a double positioning effect to ensure the positioning accuracy of the upper fitting 14. When the bottom surface of the first positioning groove 1231 is provided with the first positioning protrusion 20, the upper fitting 14 is provided with the first positioning hole 21; conversely, when the bottom surface of the first positioning groove 1231 is provided with the first positioning hole 21, the upper fitting 14 is provided with the first positioning protrusion 20. In this embodiment, the example of the first positioning groove 1231 having a first positioning protrusion 20 and the upper fitting 14 having a first positioning hole 21 is described. The first positioning groove 1231 is located on the top surface of the upper fixing plate 123.

[0048] The lower fixing plate 124 is provided with a second positioning groove 1241, and the lower fitting 15 extends into the second positioning groove 1241. A second positioning protrusion 22 is provided on one of the bottom surfaces of the second positioning groove 1241 and the lower fitting 15, and a second positioning hole 23 is provided on the other surface of the second positioning groove 1241 and the lower fitting 15, which mates with the second positioning protrusion 22. The second positioning groove 1241 achieves positioning and fixing of the lower fitting 15, and the second positioning protrusion 22 mates with the second positioning hole 23, forming a double positioning effect to ensure the positioning accuracy of the lower fitting 15. When the bottom surface of the second positioning groove 1241 has the second positioning protrusion 22, the lower fitting 15 has the second positioning hole 23; conversely, when the bottom surface of the second positioning groove 1241 has the second positioning hole 23, the lower fitting 15 has the second positioning protrusion 22. In this embodiment, the example of the second positioning groove 1241 having the second positioning protrusion 22 and the lower fitting 15 having the second positioning hole 23 is described. The second positioning groove 1241 is located on the top surface of the lower fixing plate 124.

[0049] The transverse section 122 is provided with a third positioning groove 1221, and the intermediate fitting 16 extends to the third positioning groove 1221 to achieve the effect of positioning and fixing the intermediate fitting 16. The positioning groove is provided to achieve the effect of positioning and fixing, so that the conductive component can be accurately positioned and the positional relationship between the conductive component and the corresponding fixing cavity (coaxiality, the size of the extension into the fixing cavity, etc.) can be realized.

[0050] Specifically, as shown in the attached document Figures 3-9 As shown, it also includes a manual locking component 24, which includes an operating head 241 and a screw portion 242. The operating head 241 has a gripping structure for direct hand gripping and applying rotational force. The screw portion 242 is connected to the lower end of the operating head 241, and has external threads on its outer peripheral wall. The screw portion 242 passes through the intermediate hardware 16 and connects to the transverse platen 122. The manual locking component 24 achieves the connection and fixation between the intermediate hardware 16 and the transverse platen 122, resulting in higher assembly precision for the intermediate hardware 16. Here, the manual locking component 24 can be installed and fixed without tools, which is simpler than tool operation and achieves the effect of toolless operation. Since the intermediate hardware 16 is set at an angle and the design space is limited, it is not possible to use a spring clip for pressing and fixing. Therefore, bolts are used to achieve the tightening effect and prevent the intermediate hardware 16 from shaking.

[0051] Specifically, the upper fixing plate 123 has a first notch 1232, which communicates with the first positioning groove 1231. That is, the upper fitting 14 passes through the first notch 1232 and then bends and extends into the first fixing cavity 131. The lower fixing plate 124 has a second notch 1242, which communicates with the second positioning groove 1241. That is, the lower fitting 15 passes through the second notch 1242 and then bends and extends into the second fixing cavity 132. The second notch 1242 has a positioning part 1243, the lower end of the porcelain bottle 13 abuts against the positioning part 1243, and the upper end of the porcelain bottle 13 passes through the first notch 1232. After the positioning and fixing installation is completed, the side of the porcelain bottle 13 abuts against the sidewalls of the first notch 1232 and the second notch 1242, and the positioning and fixing of the porcelain bottle 13 is achieved by two third elastic pressure plates 19.

[0052] Specifically, as shown in the attached document Figures 3-9As shown, when pouring the first fixed cavity 131 and the second fixed cavity 132, the central axis of the porcelain bottle 13 forms an angle with the height direction of the base 11, that is, the central axis of the porcelain bottle 13 is set at an angle with the Z-axis. At this time, the porcelain bottle 13 is tilted. The angle is greater than or equal to 0° and less than or equal to 45°. The tilt angle of the porcelain bottle 13 can be adjusted according to actual needs. During the pouring process, the support 12 is in a tilted state. At this time, the porcelain bottle 13 is also tilted. The tilt has two functions: first, it facilitates cement pouring; second, it makes it easier for operators to observe the state of cement setting and hardening. In addition, those skilled in the art can also adjust the angle of the support 12 according to actual needs. It should be noted that, for example, when pouring the first fixed cavity 131, its opening cannot be parallel to the horizontal direction or the opening cannot face downwards. Such operation cannot achieve cement pouring, and cement will also flow out from the first fixed cavity 131, which is obviously not in line with practical operation.

[0053] Specifically, as shown in the attached document Figures 3-9 As shown, it also includes a handle 25, which is connected to a reduction gear mechanism. An external force drives the handle 25 to rotate, which in turn drives the reduction gear mechanism. The rotation of the bracket 12 is achieved by driving the handle 25. Furthermore, the rotation effect can be precisely adjusted by the reduction gear mechanism. Alternatively, it can be driven by a motor to achieve a semi-automatic control effect.

[0054] Specifically, the reduction mechanism includes a worm gear reducer 26. During rotation, when the helix angle (lead angle) of the worm is less than the friction angle, the friction between the worm gear and the worm in the worm gear reducer 26 prevents reverse rotation. When you release the handle 25, even if the bracket 12 is carrying a heavy object or has a reverse torque, it cannot drive the worm in reverse, and the bracket 12 will be firmly fixed in place. Alternatively, when the reduction mechanism includes a conventional gear reducer, an electromagnetic brake or mechanical ratchet can be added to the end of the handle 25 or to the bracket 12 to achieve fixation, thus limiting reverse rotation and fixing the bracket 12.

[0055] Specifically, in this embodiment, the reduction ratio of the deceleration mechanism can be adjusted according to actual needs. For example, if the handle 25 rotates one revolution, the bracket 12 rotates 60°. If the handle 25 rotates six revolutions, the bracket 12 can rotate 360°.

[0056] Specifically, as shown in the attached document Figures 3-9As shown, the bracket 12 has rotating shafts 125 at both ends, and the base 11 has two support columns 111. Each support column 111 is fixed with a bearing 112. One rotating shaft 125 passes through the bearing 112 and connects to the reduction mechanism, while the other rotating shaft 125 passes through the other bearing 112. The support columns 111 are located at the upper end of the columns. The support columns 111 provide better support and fixation, making the rotation of the rotating shaft 125 more stable.

[0057] Specifically, as shown in the attached document Figures 3-9 As shown, the base 11 includes two uprights 113 and a crossbeam 114. Both ends of the crossbeam 114 are connected to the two uprights 113, forming a horizontal I-shaped structure. A support plate 116 is fixed to the lower end of each upright 113, and the support plate 116 rests against the ground. Two diagonal braces 115 are connected to the sides of each upright 113, and the two diagonal braces 115 are symmetrically arranged to form a triangular support and fixation effect. The other end of each diagonal brace 115 is connected to the support plate 116. In this embodiment, the base 11 can be formed by welding aluminum alloy. However, those skilled in the art can also use other materials for processing.

[0058] Specifically, the processing steps are as follows: Step 1: Rotate handle 25 to rotate bracket 12 to a suitable angle. This suitable angle is when the upper fixing plate 123 and lower fixing plate 124 are perpendicular to the Z-axis, with the lower fixing plate 124 located below the upper fixing plate 123. Alternatively, bracket 12 can be slightly tilted to facilitate the installation and fixation of the lower fitting 15. Once bracket 12 is rotated to its designated position, install the lower fitting 15 into the second positioning groove 1241. The other end of the lower fitting 15 is bent upwards. Finally, the second elastic pressure plate 18 presses against the lower fitting 15, thus fixing it in place. At this point, the number of lower fittings 15 matches the number of porcelain insulators 13.

[0059] Step 2: Continue rotating handle 25 to rotate bracket 12 to a suitable angle, specifically a 90° rotation, so that the upper fixing plate 123 and the lower fixing plate 124 are positioned front-to-back (i.e., bracket 12 is parallel to the bottom surface). Alternatively, bracket 12 can be slightly tilted to facilitate the installation and fixing of the porcelain bottle 13. One end of the porcelain bottle 13 passes through the second notch 1242 and abuts against the positioning part 1243, while the other end passes through the first notch 1232. At this point, ensuring the porcelain bottle 13 abuts against the positioning part 1243 achieves positioning of the porcelain bottle 13. It should be noted that after positioning, the opening of the third fixing cavity 133 faces directly upwards. Finally, pressure is applied by the two third elastic pressure plates 19 to achieve the positioning and fixing effect of the porcelain bottle 13.

[0060] Step 3: Continue rotating handle 25 to rotate bracket 12 to a suitable angle. Specifically, a suitable angle means rotating another 90° until the upper fixing plate 123 and lower fixing plate 124 are perpendicular to the Z-axis, with the upper fixing plate 123 positioned below the lower fixing plate 124. Alternatively, bracket 12 can be slightly tilted to facilitate the installation and fixation of the upper fitting 14. Once bracket 12 is rotated to its final position, install the upper fitting 14 into the first positioning groove 1231. The other end of the upper fitting 14 is bent upwards. Finally, the first elastic pressure plate 17 presses against the upper fitting 14, thus securing it in place. At this point, the number of upper fittings 14 matches the number of porcelain insulators 13.

[0061] Step 4: Continue rotating handle 25 to rotate bracket 12 to a suitable angle. Specifically, a suitable angle refers to a 90° counter-clockwise rotation, so that the upper fixing plate 123 and lower fixing plate 124 are aligned front-to-back (i.e., bracket 12 is parallel to the bottom surface). Additionally, bracket 12 can be slightly tilted to facilitate the installation and fixing of the porcelain bottle 13. Once bracket 12 is rotated to its correct position, install the intermediate fitting 16 into the third positioning groove 1221. The other end of the intermediate fitting 16 extends into the third fixing cavity 133. Then, manually lock and fix the intermediate fitting 16 using the manual locking device 24.

[0062] Step 5: Continue rotating handle 25 to rotate bracket 12 to a suitable angle. Here, bracket 12 rotates counterclockwise so that the opening of the second fixed cavity 132 faces upward at an angle, forming an angle between the central axis of porcelain bottle 13 and the Z-axis, for example, 10°. After rotating to the correct position, due to the reverse rotation restriction of the worm gear and worm, the worker can pour cement into the second fixed cavity 132 and let it stand for a period of time (this time is limited by the different cement formulas; as long as the cement does not flow out during rotation, those skilled in the art can adjust the standing time according to the actual situation, such as one hour or half an hour).

[0063] Step Six: Continue rotating handle 25 to rotate bracket 12 to a suitable angle. Here, bracket 12 rotates counterclockwise so that the opening of the first fixed cavity 131 faces upward at an angle, forming an angle between the central axis of porcelain bottle 13 and the Z-axis, for example, 10°. After rotating to the correct position, due to the reverse rotation restriction of the worm gear and worm, the worker can pour cement into the first fixed cavity 131 and let it stand for a period of time (this time is limited by the different cement formulas; as long as the cement does not flow out during rotation, those skilled in the art can adjust the standing time according to the actual situation, such as one hour or half an hour).

[0064] Step 7: Continue rotating handle 25 to rotate bracket 12 to a suitable angle, where bracket 12 is parallel to the bottom surface. Due to the reverse rotation restriction of the worm gear and worm, the worker can pour cement into the third fixed cavity 133 and let it stand for a period of time (this time is limited by the different cement formulas; as long as the cement does not flow out during rotation, those skilled in the art can adjust the standing time according to the actual situation, such as one hour or half an hour). In addition, those skilled in the art can also adjust the procedures of steps 5 to 7 according to actual needs.

[0065] Through the above seven steps, the porcelain insulator 13 can be poured. This processing device ensures the parallelism and consistency of the upper fitting 14 and lower fitting 15 in terms of intermediate dimensions. The horizontal section 122 ensures the parallelism and consistency of the intermediate fitting 16 in terms of intermediate dimensions. The worm gear reducer 26 can be easily cranked by turning the handle 25. Due to the structure of the worm gear reducer 26, reverse rotation is restricted, effectively preventing the bracket 12 from reversing and reducing the need for locking. Furthermore, the above processing device has a simple structure; both the base 11 and the bracket 12 are made of aluminum alloy, and the processing and fixing effect can be achieved through simple welding. Equipped with a worm gear reducer 26, it forms a complete processing device that is low-cost and highly practical.

[0066] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
