Description

Technical Field

[0001] This invention relates to the technical field of porcelain insulator string production equipment, specifically a multi-station fully automatic porcelain insulator string blank repair line. Background Technology

[0002] Porcelain insulator strings are important components in power construction, used to suspend conductors and insulate them from towers and the ground. Based on the assembly method, they include integrated and series structures. Integrated insulator strings are made by processing and firing multiple insulator string units together as a unified whole, facilitating installation during power construction. However, if one set of insulator string units is damaged, the entire structure becomes unusable. Series insulator strings combine two or more insulator elements together for flexible suspension, making it easy to replace damaged units individually, but the assembly is more complex.

[0003] For porcelain insulator string production technicians, it is necessary to use blanking equipment to process the blanks into corresponding shapes and structures in different parts of the blanks. Due to the special structure of the insulator string, it is difficult to complete the blanking work with a single blanking knife, and multiple types of blanking knives are required to work together.

[0004] Currently, the blanking process for porcelain insulator strings requires manual loading and unloading, as well as transfer between various blanking machines. This significantly limits the production efficiency of porcelain insulator strings, and the high degree of human intervention also makes it difficult to guarantee the quality of the output. Therefore, it is necessary to design a multi-station fully automated porcelain insulator string blanking line to effectively improve the blanking speed and efficiency, increase the production precision of porcelain insulator strings, and enhance the overall automation level of the blanking line. Summary of the Invention

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figure 1-18 The technical solution of this application, the operating principle between the components, and the operation process for producing porcelain insulator strings are explained in conjunction with the following embodiments.

[0038] Example 1

[0039] A multi-station fully automatic porcelain insulator string repair line includes a small station indexing plate 1, a large station indexing plate 2, a feeding and conveying assembly 301, a discharging and conveying assembly 302, and a driving assembly 4. The small station indexing plate 1 is evenly equipped with a feeding station 101, a discharging station 102, and a first transfer station 103. The feeding station 101 and the discharging station 102 are equipped with feeding and discharging clamps 501, and the first transfer station 103 is equipped with a transfer clamp 502. The feeding and conveying assembly 301 is arranged opposite to the feeding station 101 and the corresponding transfer clamp 502 is used to transfer the blank from the feeding and conveying assembly 301 to the feeding station 101. The discharging and conveying assembly 302 is arranged opposite to the discharging station 102 and the corresponding transfer clamp 502 is used to transfer the repaired blank from the discharging station 102 to the discharging and conveying assembly 302.

[0040] The large workstation indexing plate 2 is evenly equipped with a second transfer station 201 and multiple sets of blank trimming stations 202. The first transfer station 103 is arranged opposite to the second transfer station 201 and the blank is transferred through the corresponding transfer fixture 502. Each set of blank trimming stations 202 is equipped with a blank trimming component to perform step-by-step blank trimming processing on the blank.

[0041] The drive component 4 is poweredly connected to the small station indexing plate 1, the large station indexing plate 2, the loading and unloading transmission component 301, and the unloading transmission component 302, and the drive component 4 is used to drive the small station indexing plate 1, the large station indexing plate 2, the loading and unloading transmission component 301, and the unloading transmission component 302 to run.

[0042] Unprocessed billets are conveyed to the loading station 101 on the small station indexing plate 1 via the loading and conveying assembly 301. They are then transferred to the small station indexing plate 1 by the corresponding loading and unloading clamps 501, and transported by the small station indexing plate 1 to the first transfer station 103. From there, they are transferred to the second transfer station 201 on the large station indexing plate 2 by the transfer clamps 502. In the large station indexing plate 2, the billets are trimmed by various sets of trimming assemblies before being returned to the second transfer station. At position 201, the billet processed at the second rotating station is transferred back to the first transfer station 103 by the transfer fixture 502, and the unprocessed billet from the first transfer station 103 is transferred to the second transfer station 201 in the large station indexing plate 2 for the next billet trimming process. The trimmed billet runs on the small station indexing plate 1 to the unloading station 102, and is transferred to the unloading and conveying assembly 302 for output by the corresponding loading and unloading fixture 501.

[0043] Example 2

[0044] To ensure stable and effective processing of the billet, and to ensure that the billet can be stably transferred and moved between various components, thus completing the entire billet trimming process, the following technical solutions are provided.

[0045] It is also provided with a core post 81, a mounting base 82, and a connector 83 that are fixed in sequence from top to bottom. The top of the core post 81 has a first positioning ring groove 811 and a second positioning ring groove 812 from top to bottom. The outer side wall of the mounting base 82 has evenly provided locking grooves 821.

[0046] The blanks used for the porcelain insulator string are fixed to the mounting base 82 and arranged around the core post 81 to ensure the stable installation of the blanks. At the same time, the blanks can be moved between the components by operating the core post 81 and the mounting base 82. By driving the mounting base 82 and the blanks to rotate, and cooperating with the blank repair component, the blank repair work can be completed.

[0047] The first and second annular grooves ensure that the loading / unloading clamps 501 and the transfer clamps 502 can stably grip the core column 81, and can also effectively lock the top of the core column 81 to ensure that the core column 81 rotates stably along its own axis. The connector 83 and the locking groove 821 ensure that the blank is stably assembled on the small station indexing plate 1, the large station indexing plate 2, the loading transfer assembly 301, and the unloading transfer assembly 302.

[0048] The bottom of the connector 83 is provided with an arc-shaped transition surface, which can ensure that the connector 83 can be quickly and stably assembled onto the corresponding component involved.

[0049] Example 3

[0050] To ensure the stable operation of the small station indexing plate 1 driven by the drive component 4, and to stably transfer the billet from the loading conveyor component 301 to the small station indexing plate 1 in cooperation with the transfer fixture 502, transfer the billet on the small station indexing plate 1 to the large station indexing plate 2 for blank trimming, and transfer the trimmed billet on the large station indexing plate 2 back to the small station indexing plate 1 and further transfer it to the unloading conveyor component 302, the following technical solution is provided.

[0051] The small station indexing plate 1 includes a first fixed shaft seat 11, a first turntable 12, and a first fixed plate 13. The first fixed shaft seat 11 is arranged in a vertical direction. The first turntable 12 is rotatably mounted on the first fixed shaft seat 11 and is poweredly connected to the drive assembly 4. The first fixed plate 13 is fixedly mounted on the top of the first fixed shaft seat 11 and arranged above the first turntable 12. The loading and unloading clamps 501 and the transfer clamps 502 are assembled on the first fixed plate 13.

[0052] Three sets of locking assemblies, which are matched with the mounting base 82 and the plug 83, are evenly fixed on the first turntable 12. Each locking assembly includes a locking seat 141, a locking connector 142, a transmission rack 143, a rotating gear 144, a first synchronous pulley 145, and a first motor 146. The locking seat 141 is fixedly mounted on the first turntable 12. A first plug groove 1411, matching the plug 83, is formed at the center of the locking seat 141. An mounting cavity 1412, arranged around the first plug groove 1411, is also formed on the inner side of the locking seat 141. Multiple sets of locking assemblies are evenly formed on the locking seat 141, communicating with the mounting cavity 1412 and extending along the locking seat 141. 41. A radially arranged sliding groove 1413 is provided. A locking connector 142 is slidably installed in the sliding groove 1413 and is nested and locked with the locking groove 821. The first synchronous pulley 145 includes multiple sets that are rotatably installed in the mounting cavity 1412 and are evenly arranged. Each set of first synchronous pulleys 145 is powered by a first synchronous belt 147. A first motor 146 is fixedly installed in the mounting cavity 1412 and is fixedly connected to the axis of one set of first synchronous pulleys 145. A rotating gear 144 is fixedly connected to the axis of some of the first synchronous pulleys 145. A transmission rack 143 is fixedly connected below the locking connector 142 and is engaged with the corresponding rotating gear 144.

[0053] When the loading / unloading clamp 501 and the transfer clamp 502 clamp the top of the core column 81 and fix it onto the locking assembly, the first insertion slot 1411 ensures that the insertion connector 83 and the locking seat 141 can quickly achieve nesting combination. After that, by controlling the first motor 146 to work, the corresponding first synchronous wheel 145 is driven to rotate stably. The combination of the first synchronous wheel 145 and the first synchronous belt 147 drives each set of rotating gears 144 to rotate synchronously, thereby driving the transmission rack 143 and the locking connector 142 fixed to the transmission rack 143 to slide stably along the sliding through slot 1413, so that the locking connector 142 is inserted into the locking slot 821 to achieve stable fixation of the mounting base 82, thereby ensuring stable fixation of the blank.

[0054] When it is necessary to remove the blank fixed on the locking assembly by the loading / unloading clamp 501 and the transfer clamp 502, the first motor 146 is controlled to run in reverse so that the locking connector 142 cancels the matching locking with the locking groove 821, thereby canceling the fixing effect on the mounting base 82.

[0055] To ensure that the drive assembly 4 can drive the first turntable 12 on the small station indexing plate 1 to rotate stably, so that the locking assembly mounted on it, as well as the core column 81, mounting base 82, connector 83 and blank fixed on it, can rotate accordingly, the following technical solution is provided.

[0056] The drive assembly 4 includes a drive motor 401, a drive shaft 402, a first conical transmission gear 403, and a first conical drive gear 404. The first conical transmission gear 403 is fixedly connected to the first turntable 12. The drive shaft 402 is poweredly connected to the drive motor 401 and is rotated. The first conical drive gear 404 is fixedly connected to the drive shaft 402 and meshes with the first conical transmission gear 403.

[0057] When the drive motor 401 drives the drive shaft 402 and the first bevel drive gear 404 mounted on it to rotate, it can drive the second bevel transmission gear 405 and the first turntable 12 to rotate stably. The first turntable 12 rotates 120° in each operating cycle. During this operation, the blank on the loading and unloading clamp 501 at the loading station 101 is transferred to the locking assembly at the loading station 101 and fixed. After the rotation, the billet moves to the first transfer station 103. The transfer fixture 502 swaps the billets at the first transfer station 103 and the second transfer station 201, so that the untrimmed billet is input into the large station indexing plate 2, and the trimmed billet is input into the small station indexing plate 1. After the first turntable 12 rotates another 120°, the trimmed billet is transferred to the unloading station 102, and the unloading fixture 501 at the unloading station 102 transfers it to the unloading transmission assembly 302.

[0058] According to the above operating procedure, the blanks that have not been trimmed on the feeding and conveying component 301 can be continuously input into the large station indexing plate 2, and the blanks that have been trimmed on the large station indexing plate 2 can be output to the unloading and conveying component 302.

[0059] To ensure that the loading / unloading fixture 501 and the transfer fixture 502 can stably clamp the billet and complete their respective set operating tasks, thereby realizing the transfer of the billet between them, the following technical solution is provided.

[0060] Both the loading / unloading clamp 501 and the transfer clamp 502 include a longitudinal mounting base 51, a longitudinal lifting base 52, a transverse mounting base 53, a transverse sliding base 54, a first telescopic cylinder 55, and a second telescopic cylinder 56. The longitudinal mounting base 51 is fixedly mounted on the first fixed plate 13. The longitudinal lifting base 52 is slidably mounted in the longitudinal mounting base 51. The first telescopic cylinder 55 is fixedly mounted in the longitudinal mounting base 51 and is poweredly connected to the longitudinal lifting base 52. The transverse mounting base 53 is fixedly mounted on the longitudinal lifting base 52. The transverse sliding base 54 is slidably mounted on the transverse mounting base 53. The second telescopic cylinder 56 is fixedly mounted in the transverse mounting base 53 and is poweredly connected to the transverse sliding base 54. The transverse sliding base 54 in the loading / unloading clamp 501 is equipped with a clamping assembly 7.

[0061] The transfer fixture 502 also includes a rotating seat 57 and a second motor 58. The rotating seat 57 is rotatably mounted on the corresponding transverse sliding seat 54, and the second motor 58 is fixedly mounted on the corresponding transverse sliding seat 54 and connected to the center power of the rotating seat 57. Both ends of the rotating seat 57 are equipped with symmetrically arranged clamping components 7, and the clamping components 7 are matched and engaged with the first positioning ring groove 811 and the second positioning ring groove 812.

[0062] The longitudinal mounting base 51 ensures that the longitudinal lifting base 52 is stably installed on it. The first telescopic cylinder 55 can drive the longitudinal lifting base 52 to rise and fall stably in the vertical direction to adjust the height position of the corresponding clamping component 7. The transverse mounting base 53 is fixedly connected to the longitudinal lifting base 52 to maintain a follow-up state and can ensure that the transverse sliding base 54 is stably installed on it. The second telescopic cylinder 56 can drive the transverse sliding base 54 to slide horizontally to adjust the horizontal position of the corresponding clamping component 7.

[0063] Through the above operations, the position of the clamping component 7 can be adjusted and the core post 81 on the blank at the corresponding position can be stably clamped, and the clamped blank can be accurately transported to the corresponding position.

[0064] Regarding the transfer fixture 502, the second motor 58 on it can drive the rotating seat 57 to rotate and change position, so as to clamp and change the blanks at the first transfer station 103 and the second transfer station 201 respectively, thereby realizing the input of the blanks processed on the large station indexing plate 2 to the small station indexing plate 1, and the input of the blanks unprocessed on the small station indexing plate 1 to the large station indexing plate 2.

[0065] Example 4

[0066] To ensure that the large-station indexing plate 2 can sequentially trim unprocessed blanks input into it, and to ensure that the mounting base 82 and connector 83 with the blanks are stably assembled onto the large-station indexing plate 2 and maintain high-speed operation, so as to achieve cooperation with the trimming components to complete the trimming work, and to ensure that the large-station indexing plate 2 can be stably driven by the drive component 4, and that the large-station indexing plate 2 and the small-station indexing plate 1 operate at a specific angular velocity ratio, the following technical solutions are provided.

[0067] The large-station indexing plate 2 includes a second fixed shaft seat 21, a second turntable 22, a second fixed plate 23, a rotating pad 24, a second synchronous pulley 25, and a third motor 26. The second fixed shaft seat 21 is arranged vertically. The second turntable 22 is rotatably mounted on the second fixed shaft seat 21 and is poweredly connected to the drive assembly 4. The second fixed plate 23 is fixedly mounted on the second fixed shaft seat 21. The rotating pad 24 is rotatably mounted on the second turntable 22 and is evenly distributed. A second insertion groove 241 that fits into the insertion connector 83 is opened at the top axis of the rotating pad 24. The second synchronous pulley 25 is fixedly connected to the axis of the rotating pad 24 and arranged below the second turntable 22. Each group of second synchronous pulleys 25 is poweredly connected through a second synchronous belt 27. The third motor 26 is fixedly mounted on the second turntable 22 and is poweredly connected to one of the groups of second synchronous pulleys 25. The drive assembly 4 also includes a second conical transmission gear 405, a second conical drive gear 406, a third conical transmission gear 407, a third conical drive gear 408, and a third synchronous pulley 409. The second conical transmission gear 405 is fixed to the second turntable 22, and the third conical drive gear 408 is fixed to the drive shaft 402. The second conical drive gear 406 and the third conical transmission gear 407 are installed in a relatively rotatable manner and are respectively meshed with the second conical transmission gear 405 and the third conical drive gear 408. The third synchronous pulley 409 is fixedly connected to the shaft center of the second conical drive gear 406 and the third conical transmission gear 407. The two sets of third synchronous pulleys 409 are connected by a third synchronous belt 410.

[0068] The rotating pad 24 and the second insertion slot 241 therein can ensure that the mounting base 82 and the insertion connector 83 are stably assembled on it, and ensure that the billet is stably assembled in the large station indexing plate 2. By controlling the third motor 26 to work, and through the combination of the second synchronous pulley 25 and the second synchronous belt 27, each group of rotating pads 24 is driven to rotate stably and at high speed, thereby driving the billet to rotate stably around its own axis. It works in conjunction with each group of blank trimming components to achieve blank trimming processing.

[0069] When the drive motor 401 drives the drive shaft 402 to rotate, it can also drive the third conical drive gear 408 to rotate, which in turn drives the third conical transmission gear 407 to rotate stably. Through the combination of the third synchronous pulley 409 and the third synchronous belt 410, the second conical drive gear 406 is driven to rotate, which in turn drives the second conical transmission gear 405 and the second turntable 22 to rotate stably.

[0070] In one specific implementation scheme, the blank trimming assembly has five sets to sequentially trim different parts of the porcelain insulator string blank, and a total of six workstations are set on the large workstation indexing plate 2. Therefore, by adjusting the gear ratios among the first conical transmission gear 403, the first conical drive gear 404, the second conical transmission gear 405, the second conical drive gear 406, the third conical transmission gear 407, and the third conical drive gear 408, when the first turntable 12 rotates 120°, the large workstation indexing plate 2 rotates 60°, so that the finished blank produced by the last set of blank trimming assemblies on the large workstation indexing plate 2 can be transferred through the first transfer workstation 103 and the second transfer workstation 201, and the unprocessed blank on the small workstation indexing plate 1 is simultaneously input into the large workstation indexing plate 2.

[0071] To ensure that each set of blank trimming components can effectively trim the blank and that the sets of blank trimming components can work together to complete the overall processing of the blank, the following technical solution is provided.

[0072] The trimming assembly includes a lifting mounting frame 61, a lifting slide 62, an adjusting screw 63, a fourth motor 64, a fourth telescopic cylinder 65, a mounting slide 66, and a tool holder 67. The lifting mounting frame 61 is vertically fixed on the second fixed plate 23. The lifting slide 62 is slidably mounted on the lifting mounting frame 61. The adjusting screw 63 is rotatably mounted on the lifting mounting frame 61 and is spun into contact with the lifting slide 62. The fourth motor 64 is fixedly mounted on the lifting mounting frame 61 and is powered by the adjusting screw 63. The fourth telescopic cylinder 65 is fixedly mounted on the lifting slide 62. The mounting slide 66 is slidably mounted on the lifting slide 62 and is powered by the fourth telescopic cylinder 65. The tool holder 67 is fixedly connected to the mounting slide 66. Different shaped trimming tools are fixedly mounted on the tool holder 67 in each trimming assembly.

[0073] Due to the structural characteristics of porcelain insulator strings, different parts and directions of the porcelain insulator strings need to be processed using corresponding trimming knives. At the same time, different parts of the blank need to be processed into different shapes. Therefore, according to the actual processing requirements, multiple sets of trimming knives and trimming components need to be assembled.

[0074] When the large workstation indexing plate 2 is driven by the drive component 4, after each 60° rotation, the upstream billet can rotate to the corresponding trimming component, and complete the corresponding trimming work with the cooperation of the trimming component and the rotating pad 24.

[0075] When the fourth motor 64 drives the adjusting screw 63 to run, it can drive the lifting slide 62 to move up and down, thereby adjusting the height of the tool holder 67 and the trimming knife fixed thereon. When the fourth telescopic cylinder 65 drives the mounting slide 66 to move horizontally, it can adjust the horizontal position of the tool holder 67 and the trimming knife, thereby trimming the blank at different positions and parts.

[0076] In some implementations, during the operation of the large workstation indexing plate 2, the blank needs to be processed by the blank trimming assembly. The dust generated when the blank trimming knife cuts the blank will pollute the surrounding environment. To solve the problem of dust pollution diffusion, the following technical solutions are provided.

[0077] The outer perimeter of the large workstation indexing plate 2 is equipped with a dust cover 91. The dust cover 91 has a blank passage 911 arranged between the first transfer station 103 and the second transfer station 201. A dust collection cover 92 is fixedly installed on the inner side of the top of the dust cover 91, and a negative pressure pump 93 is installed on the dust collection cover 92.

[0078] The dust cover 91 effectively prevents dust generated during blank trimming from escaping. The dust is then drawn away by the negative pressure pump 93 and the dust collection cover 92 for unified treatment. The blank inlet 911 ensures that the blank can stably enter and exit the dust cover 91 and be assembled on the large station indexing plate 2 and the small station indexing plate 1.

[0079] To ensure that the third synchronous belt 410 is arranged through the dust cover 91 so as to realize the linkage between the large workstation indexing plate 2 and the drive component 4, an installation port 912 is also provided on the dust cover 91, and the third synchronous belt 410 is arranged through the installation port 912.

[0080] Example 5

[0081] To further improve the stability of the billet rotating at high speed around its own axis in the large station indexing plate 2, the following technical solution is provided.

[0082] A mounting bracket 221 is fixedly connected to the second turntable 22, and clamping components 7 are evenly assembled on the mounting bracket 221. The clamping components 7 include a mounting box 71, a clamping seat 72, a third telescopic cylinder 73, and a connecting rod 74. The mounting box 71 is fixedly installed on the mounting bracket 221, the transverse sliding seat 54, or the rotating seat 57. The clamping seat 72 includes two sets symmetrically arranged and slidably installed in the mounting box 71, and the clamping seat 72 has a semi-circular slot 721 that nests and matches the first positioning ring groove 811 and the second positioning ring groove 812. The third telescopic cylinder 73 is fixedly installed in the mounting box 71, and the two ends of the connecting rod 74 are hinged to the third telescopic cylinder 73 and the clamping seat 72, respectively. The mounting bracket 221 ensures that the matching clamping components are installed at a high position in the large workstation indexing plate 2 to position the core column 81 on the top of the billet.

[0083] When the third telescopic cylinder 73 is retracted, the two sets of clamping seats 72 can be driven to slide relative to each other in the mounting box 71 through the two sets of connecting rods 74. The two sets of semi-circular slots 721 are attached and positioned to the first positioning ring groove 811 or the second positioning ring groove 812 on the top of the core column 81, while the core column 81 can maintain its rotation.

[0084] The clamping component mounted on the mounting bracket 221 is positioned with the second positioning ring groove 812 of the core column 81, while the clamping component 7 mounted on the transfer fixture 502 and the loading / unloading fixture 501 is positioned with the first positioning ring groove 811 of the core column 81, so that the two sets of clamping components 7 are staggered to facilitate the stable assembly of the blank in the first transfer station 103 and the second transfer station 201.

[0085] Example 6

[0086] To ensure that the loading and unloading conveyor components 301 and 302 can respectively convey unprocessed blanks to the small station indexing plate 1 and receive processed blanks conveyed from the lower station indexing plate, while ensuring that the loading and unloading conveyor components 301 and 302 are driven by the drive component 4 to operate stably, the following technical solution is provided.

[0087] Both the feeding and unloading conveying components 301 and 302 include a mounting plate 31, a rotating roller 32, a conveying chain plate 33, a transmission sprocket 34, and a bearing pad 35. The rotating roller 32 includes two sets that are rotatably mounted on both ends of the mounting plate 31. The transmission sprocket 34 is fixedly connected to the shaft of the rotating roller 32, and the two sets of transmission sprockets 34 are driven by a chain 36. The conveying chain plate 33 is wound around the two sets of rotating rollers 32 and is arranged in a taut manner. The bearing pad 35 is evenly fixed on the outer side of the conveying chain plate 33, and the bearing pad 35 is provided with a third insertion groove 351 that fits into the insertion joint 83. The drive assembly 4 also includes a fourth conical transmission gear 411, a fourth conical drive gear 412, and a universal coupling 413. The fourth conical drive gear 412 is fixedly mounted on the drive shaft 402. The fourth conical transmission gear 411 includes two sets symmetrically arranged and both meshing with the fourth conical drive gear 412. The rotating rollers 32 in the loading and unloading conveying assembly 301 and the unloading conveying assembly 302 are connected to the fourth conical transmission gear 411 on the corresponding side through the universal coupling 413.

[0088] To ensure the stability of the rotating drum 32 and the transmission chain plate 33 during operation, teeth are evenly fixed to the rotating drum 32, and meshing grooves that mesh with the teeth are opened on the inner side of the transmission chain plate 33. To ensure the stable installation of the bearing pad 35 on the transmission chain plate 33, each set of bearing pads is fixed to an independent single chain plate unit.

[0089] Since the two sets of fourth conical transmission gears 411 are symmetrically arranged, when the drive motor 401 drives the drive shaft 402 and the fourth conical drive gear 412 to rotate, the two sets of fourth conical transmission gears 411 will rotate in opposite directions. Consequently, the transmission chain plates 33 in the loading and unloading transmission components 301 and 302 will run in opposite directions, thereby achieving the loading and unloading operation settings.
