Description

TECHNICAL FIELD

[0002] Insulators are key components for supporting conductors and insulating current in power systems, commonly used in power transmission lines and substations. Insulator green body repairing is a core process in ceramic manufacturing. On the initially formed green body, workers use green body repairing knives to cut out the three-dimensional shape, spacing and contour of the shed from top to bottom on the rotating green body, forming the final appearance and structure. This process directly determines the mechanical strength, electrical performance and long-term reliability of the insulator.

[0020] Please see Figures 1-12 The present invention provides the following technical solution: a blank-repairing device for insulator production, comprising a workbench 1, an insulator 2, a clamping assembly 3, a blank-repairing assembly 4, a support assembly 5, and a coating assembly 6.

[0021] The workbench 1 is placed on the ground, and the insulator 2 is placed in the workbench 1 during work and is processed, the clamping assembly 3 is arranged in the workbench 1, the clamping assembly 3 is used for clamping and fixing the insulator 2, and the insulator 2 is driven to rotate around the axis during processing. The roughing assembly 4 is slidably installed in the workbench 1, and the roughing assembly 4 can move horizontally to approach or move away from the insulator 2, and when approaching, the roughing assembly 4 can process the rough parts of the insulator 2. The support assembly 5 is slidably installed in the workbench 1, and the support assembly 5 can move horizontally and approach the rotation center of the insulator 2 to support the processed umbrella skirt. The coating assembly 6 is arranged on the support assembly 5, and the coating assembly 6 can be used to apply roughing liquid to the umbrella skirt of the insulator 2 after processing, and the exposed capillary holes after cutting are closed through the infiltration and micro-dissolution of the roughing liquid, the scratches left by the roughing assembly 4 during processing are eliminated, the surface smoothness of the insulator 2 is improved, and normal glazing can be ensured subsequently.

[0022] As shown in Figures 1-3 The clamping assembly 3 includes a placing disc 31 rotatably installed in the workbench 1, and the columnar rough of the insulator 2 to be processed is placed on the placing disc 31. A first driving device 32 is arranged in the workbench 1, and the output end of the first driving device 32 is connected to the bottom of the placing disc 31. The placing disc 31 can be driven to rotate around the axis in the workbench 1 by the first driving device 32. A limiting disc 33 is slidably arranged in the workbench 1, and the limiting disc 33 is arranged above the placing disc 31 and can rotate around the axis. The rotation shafts of the placing disc 31 and the limiting disc 33 coincide, and the rough of the insulator 2 can be placed between the limiting disc 33 and the placing disc 31. A second driving device 34 is arranged on the top of the workbench 1, and the output end of the second driving device 34 is rotatably connected to the top of the limiting disc 33. The limiting disc 33 can be driven to move up and down in the workbench 1 by the second driving device 34.

[0023] During work, the rough of the insulator 2 is first placed in the placing disc 31, and then the second driving device 34 controls the limiting disc 33 to move downward to contact the upper surface of the rough of the insulator 2 and apply a certain pressure to the rough. Then the first driving device 32 drives the placing disc 31 to rotate the rough of the insulator 2, and the limiting disc 33 is also driven to rotate under the action of the friction force between the rough and the limiting disc 33.

[0024] As shown in Figures 2-3As shown, the trimming assembly 4 includes a tool holder 41 slidably disposed inside the worktable 1. The tool holder 41 is vertically arranged and can slide horizontally along the inside of the worktable 1 to approach or move away from the insulator 2. A trimming blade 42 is slidably disposed on the tool holder 41 and can slide up and down along the tool holder 41. During operation, the tool holder 41 controls the trimming blade 42 to approach the insulator 2 blank, and then the up and down movement of the trimming blade 42 is used to trim the blank. A first control assembly (not shown in the figure) is provided inside the worktable 1 to control the movement of the tool holder 41 and the trimming blade 42.

[0025] like Figures 2-6 As shown, the support assembly 5 includes a support frame 51 slidably disposed inside the workbench 1. Two sets of support frames 51 are staggered horizontally and symmetrically arranged on the side away from the trimming assembly 4. Guide blocks 52 are horizontally slidably disposed on the support frame 51 near the insulator 2. Multiple sets of guide blocks 52 are disposed vertically along the support frame 51. The guide blocks 52 correspond to the sheds on the insulator 2, and the guide blocks 52 on adjacent support frames 51 are staggered, meaning that multiple sets of guide blocks 52 on the same support frame 51 correspond to the sheds spaced apart on the insulator 2. The guide blocks 52 on two sets of support frames 51 can cooperate with all the sheds. Multiple sets of third drive devices 53 are disposed on the side of the support frame 51 away from the insulator 2. The output end of the third drive device 53 is connected to the guide block 52, and the third drive device 53 can drive the guide block 52 to reciprocate along the support frame 51 towards or away from the insulator 2. A lifting block 54 is slidably connected to the bottom of the guide block 52. A fourth drive device 541 is provided on the guide block 52. The output end of the fourth drive device 541 is connected to the lifting block 54, and the lifting block 54 can be driven to move up and down along the guide block 52 through the fourth drive device 541. A second control component (not shown in the figure) is provided inside the worktable 1 to control the movement of the support frame 51.

[0026] like Figures 4-10As shown, the lifting block 54 is provided with a positioning block 55 on the side close to the insulator 2, the positioning block 55 can slide up and down along the lifting block 54, the positioning block 55 is connected with a first elastic member 551, the other end of the first elastic member 551 is connected with the lifting block 54, the first elastic member 551 can control the positioning block 55 to return to the initial position when not under force, in the embodiment, the first elastic member 551 is provided as a spring. The positioning block 55 is rotatably connected with a support block 56 on the side close to the insulator 2, the support block 56 is connected with a second elastic member 561 at the position of the rotation shaft, the other end of the second elastic member 561 is connected with the positioning block 55, the second elastic member 561 can control the support block 56 to rotate to the initial position when not under force, in the embodiment, the second elastic member 561 is provided as a torsion spring. The support block 56 is rotatably connected with a roller 57 on the side away from the positioning block 55, the diameter of the roller 57 is smaller than the minimum distance between the adjacent two sheds of the insulator 2, so that the roller 57 can be inserted between the two sheds, the outer side of the roller 57 is covered with a layer of flexible water-absorbing material, such as polyurethane sponge or hydrophilic modified rubber, so that the outer side of the roller 57 has the ability of deformation and water absorption at the same time, and the material can be replaced or cleaned to ensure normal use and maintenance. In the initial state, the support block 56 is provided in an inclined manner relative to the positioning block 55 under the action of the second elastic member 561, at this time, the side of the roller 57 away from the support block 56 is provided in an inclined upward manner, and when the support block 56 rotates to the limit position, the roller 57 can be kept in a horizontal or vertical state.

[0027] When the insulator 2 is processed by the trimming assembly 4, the fourth driving device 541 controls the lifting block 54 to move up and down and adjust the position of the roller 57, so that the roller 57 is located at the bottom of the processed umbrella skirt. Then the third driving device 53 controls the guide block 52 to move close to the insulator 2, and the roller 57 is inserted into the bottom of the umbrella skirt. Then the fourth driving device 541 controls the lifting block 54 to continue to move up, and when the roller 57 contacts the bottom surface of the umbrella skirt, the support block 56 starts to rotate around the axis, and the roller 57 stops moving after it is in close contact with the bottom surface of the umbrella skirt. At this time, the second elastic member 561 is forced to twist. Then the lifting block 54 continues to move up, and at this time, the lifting block 54 moves up relative to the positioning block 55, and the first elastic member 551 starts to deform under stress, and the roller 57 starts to apply support force to the bottom surface of the umbrella skirt. Since the insulator 2 is in a rotating state during processing, the roller 57 rotates around the axis together. When the trimming assembly 4 processes the second umbrella skirt above the insulator 2, the roller 57 on the adjacent support frame 51 starts to approach the umbrella skirt and continues to support it. The rollers 57 on the two groups of support frames 51 are staggered to prevent interference when the rollers 57 on the same support frame 51 support adjacent umbrella skirts, and to ensure that each umbrella skirt can be supported after being processed. The roller 57 can be adjusted in angle to facilitate insertion into the bottom of the umbrella skirt and to match the angle and shape of the bottom of the umbrella skirt. The flexible material covering the outer side of the roller 57 avoids direct contact between the hard support and the processing surface, thereby preventing scratching. The flexible material also has a certain friction with the umbrella skirt to prevent the umbrella skirt from flapping and cracking due to large centrifugal force when the insulator 2 rotates. The first elastic member 551 can provide constant and soft support force to adapt to the slight unevenness of the umbrella skirt and avoid deformation caused by over-supporting or invalidity caused by under-supporting.

[0028] As shown in Figures 5-9 , the bottom of the side of the positioning block 55 close to the support block 56 is rotatably provided with a positioning column 58, the positioning column 58 is provided with a protrusion 581, the end of the protrusion 581 away from the rotation axis can contact the bottom of the support block 56, and the positioning block 55 and the side of the positioning column 58 are provided with matching scale lines 582. Before processing, the worker can rotate the positioning column 58 to the desired angle and fix it, so that the scale lines 582 at the corresponding positions on the positioning block 55 and the positioning column 58 are aligned, and then the position of the end of the protrusion 581 away from the rotation axis is adjusted. When the roller 57 is in contact with and completely matches the bottom surface of the umbrella skirt, the bottom of the support block 56 is in contact with the end of the protrusion 581 away from the rotation axis, and the support block 56 no longer rotates under the limitation of the protrusion 581. The protrusion 581 can adjust and support the rotation angle of the support block 56, and then adjust the inclination angle of the roller 57, so that it can adapt to the inclination angle of the bottom of the umbrella skirt and meet the support requirements of the bottom of the umbrella skirt of different insulators 2.

[0029] As shown in Figure 5 , Figure 6 and Figure 8As shown, the positioning block 55 is provided with a sensing part 552, which can be a magnetic induction displacement sensor. The lifting block 54 is provided with an indicating plate 542 cooperating with the sensing part 552. When the positioning block 55 slides up and down along the lifting block 54, the sensing part 552 always corresponds to the indicating plate 542, and can detect the displacement of the positioning block 55 relative to the lifting block 54, so as to judge the stress degree of the first elastic member 551 and the supporting force of the roller 57, so that the supporting force of the roller 57 is always maintained within a fixed range. If the displacement of the positioning block 55 is abnormally increased, it indicates that the current supporting force is insufficient to balance the gravity of the shed, and the shed has a risk of deformation under the influence of gravity. At this time, the lifting block 54 is controlled to move upward, so as to increase the supporting force of the roller 57 and prevent the deformation of the shed.

[0030] As shown in Figures 8-12 The coating assembly 6 includes guide shafts 61 rotatably arranged on both sides of the supporting block 56. The two groups of guide shafts 61 are in the same plane as the rotation axes of the rollers 57. The supporting block 56 is hollow inside. The rollers 57 are hollow inside and communicate with the internal cavities of the supporting block 56 to form a flow-through cavity. The supporting block 56 is provided with a liquid inlet 62 on the side away from the rollers 57. The green body repairing liquid can be fed into the supporting block 56 through the liquid inlet 62. A push block 63 is slidably arranged inside the supporting block 56 and located between the liquid inlet 62 and the rollers 57. The supporting block 56 is provided with a closing block 562 cooperating with the push block 63. When the push block 63 slides on the closing block 562, the internal cavity of the supporting block 56 is divided into two parts. When the push block 63 slides away from the closing block 562, the internal cavity of the supporting block 56 is completely communicated. A third elastic member 631 is connected to the side of the push block 63 close to the rollers 57, and the other end of the third elastic member 631 is connected to the inside of the supporting block 56. The third elastic member 631 can control the push block 63 to contact the closing block 562 and divide the internal cavity of the supporting block 56 when not stressed. In the embodiment, the third elastic member 631 is a spring. A plurality of liquid outlets 571 are formed in the rollers 57. The liquid outlets 571 are in contact with the coating material on the outer side of the rollers 57. After the green body repairing liquid is fed into the rollers 57 through the flow-through cavity in the supporting block 56, the liquid outlets 571 can flow out to the flexible water-absorbing material coated on the outer side of the rollers 57 and wet the flexible material, which is used for coating the shed of the insulator 2.

[0031] The push block 63 is provided with a limiting sleeve 632 at both ends, which is matched with the guide shaft 61, penetrates the supporting block 56 and extends to both ends of the supporting block 56, and can slide along the outer wall of the guide shaft 61. The limiting sleeve 632 is provided with a helical groove 633 in the moving direction, and the guide shaft 61 is provided with a sliding column 611 which slides in the helical groove 633. Such design ensures that when the push block 63 slides in the supporting block 56, the sliding column 611 reciprocates along the helical groove 633, drives the guide shaft 61 to rotate as a fixed shaft, and the rotating directions of the two guide shafts 61 are the same. The guide shaft 61 is rotatably connected with an extension cylinder 64, one end of the guide shaft 61 is connected with a fourth elastic member 612, the other end of the fourth elastic member 612 is connected with the extension cylinder 64, and the fourth elastic member 612 is a torsion spring in the embodiment. The extension cylinder 64 is provided with a scraper 641 close to the roller 57, and in the initial state, the scraper 641 is in the same plane with the rotating axis of the roller 57 under the action of the fourth elastic member 612.

[0032] After the insulator 2 is finished, the uppermost supporting block 56 is first filled with a finishing liquid, the push block 63 in the supporting block 56 moves to the side of the roller 57 under the pressure of the liquid and compresses the third elastic member 631 until it is out of contact with the closing block 562. At this time, the liquid is introduced into the roller 57 and the material on the outer side of the roller 57 is soaked through the liquid outlet hole 571, and the bottom of the insulator 2 is coated through the outer side of the roller 57. In the coating process, there is a friction force between the roller 57 and the insulator 2, which makes it rotate passively with the insulator 2 to ensure uniform coating. At this time, the guide shaft 61 drives the extension cylinder 64 to rotate under the cooperation of the sliding column 611 and the helical groove 633. At this time, one of the scrapers 641 on both sides of the roller 57 rotates upward and the other rotates downward. After the upward rotating scraper 641 contacts the bottom of the umbrella skirt, the fourth elastic member 612 is twisted under stress, which makes the guide shaft 61 rotate relative to the extension cylinder 64, and the pressure on the bottom of the umbrella skirt is applied through the scraper 641, and the excess liquid is scraped off through the scraper 641, so that the finishing liquid is uniformly distributed and fills the surface micropores, forming a liquid film with uniform thickness and smooth surface. Prevent uneven distribution of liquid film thickness and affect the coating quality.

[0033] Subsequently, the uppermost lifting block 54 drives the rollers 57 to move downward to coat the upper surface of the adjacent umbrella skirt, while the rollers 57 at the bottom of the umbrella skirt remain unchanged to support the umbrella skirt during coating. At this time, the scraper 641 rotates downward and contacts the upper surface of the umbrella skirt to scrape the position. Since the support block 56 can drive the rollers 57 to rotate around the axis, and the inclination angle of the upper surface of the umbrella skirt is large, it can adapt to the inclination angle of the upper surface of the umbrella skirt to ensure that the umbrella skirt of the insulator 2 can be uniformly coated. Subsequently, the rollers 57 at the position move downward to continue coating the umbrella skirt below. At this time, the uppermost rollers 57 move in the opposite direction and continue to support the coated umbrella skirt to prevent the umbrella skirt from deforming during coating. When all the umbrella skirts are coated, the lifting block 54 returns to the initial state, and the rollers 57 are between the adjacent umbrella skirts. Finally, the support frame 51 drives the rollers 57 away from the insulator 2, and the processed insulator 2 is removed and placed into a new blank for the next round of processing.
