[0002] The disc-shaped suspension porcelain insulator is a type of porcelain insulator and one of the key components in the power system. It is widely used in high-voltage overhead transmission and distribution lines, mainly playing the role of insulation and fixing conductors. The disc-shaped suspension porcelain insulator is composed of a porcelain body, a glue material, a steel cap, and a steel foot fitting. In the production and processing of the disc-shaped suspension insulator, after the clay is pressed into an insulator-shaped blank in a mold, it needs to be fine-trimmed to ensure that the shape and size of the blank meet the production requirements after a series of production processes. At present, in the process of fine-trimming the blank, the blank is generally positioned manually, and then processed with a fine-trimming knife. There is a lack of measures for automatic positioning of the blank, and it relies too much on manual operation, which increases the workload of the staff, and there are problems of inaccurate and inconsistent positioning.

The moving end of the third driving member 20 is connected to the movable plate 19, and is used to drive the movable plate 19 to rise and fall; a driving motor 18 is installed on the movable plate 19, and a support rod 12 is provided on the output shaft of the driving motor 18. An opening is provided on the top wall of the working box 6, and the opening is located directly above the support rod 12 for the support rod 12 to pass through, and a fixing component is provided on the support rod 12; a plurality of second driving members 10 (such as electric telescopic rods) are provided on the top wall of the working box 6 Cylinder), several second driving members 10 are distributed in a ring shape on the outside of the support rod 12, and a support plate 11 is provided on the moving end of the several second driving members 10. A guide hole is opened on the side of the support plate 11 away from the second driving member 10, and a guide rod is slidably inserted in the inner cavity of the guide hole. A supporting spring is installed between the guide rod and the guide hole, and a push plate 16 is installed on the end of the guide rod away from the support plate 11. A first pressure sensor 17 is installed on the side wall of the support plate 11 facing the push plate 16. The first pressure sensor 17 is connected to the central control device 8 for transmitting information to the central control device 8.

[0044] See also Figure 1 A first telescopic member 3 (such as an electric telescopic rod) is provided on the mounting frame 2, and a pressing member 4 (the pressing member 4 can be a block-shaped member) is provided on the moving end of the first telescopic member 3.

[0045] It should be noted that the pressing member 4 is rotatably mounted on the moving end of the first telescopic member 3, and the pressing member 4 rotates with the axis of the moving end of the first telescopic member 3 as the center; an electric cylinder is installed on the workbench 1, and the electric cylinder is used to push the working box 6 to move so that the distance between the working box 6 and the finishing knife 13 can be adjusted; a first driving member 5 (such as an electric telescopic rod) is installed on the mounting frame 2, and the first driving member 5 is used to move with the first telescopic member 3, so that when the working box 6 moves, the first telescopic member 3 can also move, ensuring that the pressing member 4 is always directly above the support rod 12.

[0046] A method for automatically positioning and fine-tuning the outer contour of a disc-shaped suspension porcelain insulator, the steps are as follows:

[0047] First, the porcelain insulator to be processed (the porcelain insulator refers to a blank pressed from mud) is placed above the working box 6 and placed between a plurality of push plates 16;

[0048] Second, the second driving member 10 works, so that the support plate 11 moves with the push plate 16 (moves to the central area of ​​the working box 6), contacts the porcelain insulator, and pushes the porcelain insulator to the center of the working box 6. When the porcelain insulator cannot move (the porcelain insulator after drying is strong and will not be deformed by squeezing), the push plate 16 moves closer to the support plate 11 and presses the first pressure sensor 17 (the second driving member 10 continues to move the support plate 11. Since the push plate 16 cannot move, the distance between the push plate 16 and the support plate 11 will be reduced). After the central control device 8 receives the pressure of the first pressure sensor 17, it controls the third driving member 20 to work, drives the moving plate 19, the driving motor 18 and the support rod 12 to move upward, so that the support rod 12 is inserted into the hole of the porcelain insulator (the hole position is as shown in FIG. Fig.13 As shown), the fixing assembly is triggered to automatically position the porcelain insulator, and at the same time, the central control device 8 controls the first telescopic member 3 to move the pressing member 4 downward, so that the pressing member 4 contacts the top of the upward porcelain insulator (at this time, the third driving member 20 has stopped rising);

[0049] It should be noted that a pressure sensor is installed at the bottom of the pressing member 4. When the pressing member 4 contacts the top of the porcelain insulator, the pressure sensor is squeezed. After the central control device 8 receives the information that the pressure sensor is under pressure, it will control the first telescopic member 3 to stop moving downward; after the support rod 12 moves upward to move the porcelain insulator out from between the plurality of push plates 16, the push plate 16 is reset under the action of the supporting spring, so that the pressure on the first pressure sensor 17 disappears. After detecting that the pressure on the first pressure sensor 17 disappears, the central control device 8 will control the second driving member 10 to contract, so that the support plate 11 and the push plate 16 are reset;

[0050] Third, after the porcelain insulator is positioned, the driving motor 18 drives the support rod 12 to rotate with the porcelain insulator, and the finishing tool is controlled by the central control device 8 to finish the outer contour of the porcelain insulator (the outer contour is as shown in FIG. Fig.13 shown);

[0051] It should be noted that the central control device 8 controls the driving assembly to raise and lower the second telescopic member 9 to change the height of the finishing knife 13. The central control device 8 controls the extension and retraction of the second telescopic member 9 to move the finishing knife 13 toward or away from the porcelain insulator. The central control device 8 controls the extension and retraction of the fourth driving member 37 to change the angle of the finishing knife 13. The central control device 8 controls the working step sequence of the finishing tool and the shape and size of the porcelain insulator to be fine-tuned according to a pre-set program. This technology belongs to the prior art and is not described in detail here.

[0052] In this embodiment, as a further optimized solution, please refer to Figure 1 An infrared irradiator 50 is provided on one side of the pressing piece 4, and the infrared irradiator 50 irradiates the top of the working box 6 to form a red circle on the top of the working box 6. The staff puts the blank into the red circle to complete a preliminary positioning; an adsorption hole is provided at the bottom of the pressing piece 4 (the pressing piece 4 is made of block rubber material), and the adsorption hole is connected to an adsorption device (such as a pump) through a conduit. After the bottom of the pressing piece 4 is fitted with the top of the blank, the adsorption device evacuates air to form a negative pressure between the pressing piece 4 and the blank, and the two are connected and fixed to avoid relative movement between the pressing piece 4 and the blank, thereby protecting the blank.

[0053] In this embodiment, as a further optimized solution, please refer to Figure 5 and Figure 6 The fixing assembly includes a placement groove provided on the side wall of the support rod 12, a fixed block 29 slidably provided in the inner cavity of the placement groove, a second elastic member 30 (spring) provided between the fixed block 29 and the placement groove, a slot 27 provided on the top wall of the support rod 12, a movable block 24 slidably provided in the inner cavity of the slot 27, a first elastic member 25 (spring) provided between the movable block 24 and the slot 27, and a flexible connecting member 31 (such as a rope) provided between the fixed block 29 and the movable block 24; when the support rod 12 is not in contact with the porcelain insulator, the first elastic member 25 applies force to the movable block 24, so that the top end of the movable block 24 is in the support rod 12, at this time, the movable block 24 will pull the flexible connector 31 and apply force to the fixed block 29, so that the fixed block 29 is completely in the inner cavity of the placement groove; when the third driving member 20 drives the support rod 12 to move upward, so that the top of the support rod 12 is inserted into the hole of the porcelain insulator, the movable block 24 is squeezed into the inner cavity of the slot 27, so that the pulling force applied by the movable block 24 to the flexible connector 31 disappears, and the restriction on the fixed block 29 is released. Under the push of the elastic force of the second elastic member 30, the fixed block 29 moves to the outside of the placement groove and contacts the inner wall of the hole of the porcelain insulator, fixing the porcelain insulator on the support rod 12.

[0054] It should be noted that there are multiple (such as two, three, four, etc.) fixing blocks 29, mounting grooves, second elastic members 30 and flexible connectors 31, which are distributed in a ring shape on the side wall of the support rod 12; they are used to increase the contact area between the fixing block 29 and the inner wall of the hole of the porcelain insulator, thereby improving the stability of the positioning of the porcelain insulator.

[0055] In this embodiment, as a further optimized solution, please refer to Figure 6 The movable block 24 and the top of the support rod 12 are both provided with a rolling ball 28, which reduces the friction between the movable block 24, the support rod 12 and the porcelain insulator, making it more convenient to adjust the position of the porcelain insulator above the support rod 12.

[0056] In this embodiment, as a further optimized solution, please refer to Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 A mounting groove 34 is provided on the side wall of the support rod 12, a moving block 22 is slidably provided in the inner cavity of the mounting groove 34, a third elastic member 35 (spring) is provided between the mounting groove 34 and the moving block 22, a mounting hole is provided in the support rod 12, a connecting rod 26 is slidably provided in the inner cavity of the mounting hole (the connecting rod 26 can move up and down), a second magnetic block 33 is provided on the top of the connecting rod 26, a first magnetic block 32 is provided on the fixed block 29, the first magnetic block 32 and the second magnetic block 33 have opposite magnetic poles on one side close to each other, an attraction is generated between the two, and the bottom end of the connecting rod 26 is connected to the second magnetic block 33. The top wall of the moving block 22 is fitted, and the top wall of the moving block 22 is an inclined surface; a limiting sleeve 21 (the limiting sleeve 21 is equivalent to a sleeve) is provided in the inner cavity of the working box 6, and the limiting sleeve 21 is sleeved on the outer wall of the support rod 12 (the limiting sleeve 21 does not contact the support rod 12), and the limiting sleeve 21 is above the moving block 22; when the third driving member 20 drives the moving plate 19, the driving motor 18 and the support rod 12 to move upward, the moving block 22 will enter the inner cavity of the limiting sleeve 21 (the inner cavity of the limiting sleeve 21 is horn-shaped, and the lower middle opening of the inner cavity of the limiting sleeve 21 is large). The upper opening is convenient for the moving block 22 to enter the inner cavity of the limiting sleeve 21). The moving block 22 is restricted by the limiting sleeve 21 and completely enters the inner cavity of the mounting groove 34, so that the contact area between the top of the moving block 22 and the bottom of the connecting rod 26 changes, and the connecting rod 26 moves downward, so that the second magnetic block 33 moves downward and staggers with the first magnetic block 32, so that the magnetic attraction between the two disappears, and the restriction on the fixed block 29 is released; when the third driving member 20 drives the moving plate 19, the driving motor 18 and the support rod 12 to move downward and reset, the moving block 22 moves out of the limiting sleeve 21. The movable block 22 is moved outwardly to release the restriction on the movable block 22. Under the action of the third elastic member 35, part of the movable block 22 is moved to the outside of the mounting groove 34. At this time, the bottom end of the connecting rod 26 contacts the highest area of ​​the top of the movable block 22, so that the connecting rod 26 moves up with the second magnetic block 33. The second magnetic block 33 and the first magnetic block 32 are on the same horizontal line, and the two will attract each other, so as to completely receive the fixed block 29 into the inner cavity of the placement groove, so as to release the fixation of the fixed block 29 to the porcelain insulator, so that the processed porcelain insulator can be removed from the support rod 12.

[0057] It should be noted that the limit sleeve 21 is slidably installed in the inner cavity of the working box 6, and the limit sleeve 21 can move up and down. Because the limit sleeve 21 is in the shape of a trumpet, the moving block 22 cannot pass through the limit sleeve 21 after moving up and entering the inner cavity of the limit sleeve 21. When the support rod 12 continues to move up, the moving block 22 will move upward with the limit sleeve 21.

[0058] It should also be noted that the working box 6 and the support rod 12 can be split into two parts, so that the components inside the working box 6 and the support rod 12 can be replaced and repaired.

[0059] Example 2

[0060] As a further optimized solution of Example 1, please refer to Figure 2 , Figure 4 , Fig. 9 , Fig.10 and Fig.11 A groove is provided on the top wall of the working box 6, and a bracket 14 is placed in the inner cavity of the groove, so that the top wall of the bracket 14 is flush with the top wall of the working box 6, and the top wall of the bracket 14 is in contact with the bottom of the mounting plate 36. A support block 23 is provided on the top wall of the limiting sleeve 21, and a slot is provided on the bottom wall of the bracket 14, and the slot is directly above the support block 23; a storage groove 39 is provided on the side of the mounting plate 36 away from the second telescopic member 9, and a movable plug block 38 is provided on the side of the finishing knife 13 facing the mounting plate 36. The movable plug block 38 is slidably inserted in the inner cavity of the storage groove 39, and a fourth elastic member 40 (spring) is provided between the movable plug block 38 and the storage groove 39. A second pressure sensor 41 and an electromagnet 42 are provided in the inner cavity of the storage groove 39. The second pressure sensor 41 is connected to the central control device 8 for transmitting information to the central control device 8, and the electromagnetic The iron 42 is controlled by the central control device 8, and the movable plug 38 is made of a metal material that can be magnetically adsorbed, such as iron; the driving component includes a lifting member 46 (the lifting member 46 refers to a rack, which is slidably mounted on the side wall of the bracket 7, and the rack can move up and down), a fifth driving member 43 (including a motor and a gear mounted on the motor output shaft, the motor is mounted on the bracket 7, and the gear is meshed with the rack), two clamping blocks 44 and a sixth driving member 45 (such as an electric telescopic rod), the fixed end of the second telescopic member 9 is slidably mounted on the bracket 7 (the second telescopic member 9 can move up and down), the two clamping blocks 44 are slidably mounted on the fixed end of the second telescopic member 9, the two clamping blocks 44 are on both sides of the rack, the sixth driving member 45 is mounted on the fixed end of the second telescopic member 9, and the moving end of the sixth driving member 45 is connected to the clamping block 44.

[0061] It should be noted that when the third driving member 20 drives the movable plate 19 and other components to move, the limit sleeve 21 moves upward, and will move the support block 23 upward, so that it is inserted into the slot of the bracket 14, and moves the bracket 14 upward; because the mounting plate 36 is above the bracket 14, the mounting plate 36 moves upward together with the bracket 14, and rises with the finishing knife 13 (so that the finishing knife 13 and the bottom of the porcelain insulator are at the same height), until the third driving member 20 stops moving (the moving distance of the third driving member 20 is controlled by the central control device 8), the central control device 8 controls the second telescopic member 9 to extend, so that the mounting plate 36 brings the finishing knife 13 closer to the side wall of the porcelain insulator, and when the finishing knife 13 fits with the side wall of the porcelain insulator, the second telescopic member 9 continues to When the central control device 8 is working, the movable plug block 38 moves toward the inside of the storage groove 39 until the second pressure sensor 41 is pressed. After receiving the information that the second pressure sensor 41 is pressed, the central control device 8 controls the second telescopic member 9 to stop working, and controls the electromagnet 42 to generate magnetic force to adsorb the movable plug block 38 and fix the finishing tool 13, and controls the sixth driving member 45 to drive the two clamping blocks 44 to move closer to each other and contact the rack to clamp the rack (when the fifth driving member 43 drives the rack to move, it brings the second telescopic member 9 up and down), and then the central control device 8 controls the finishing tool to process the porcelain insulator according to the set program; the above method is used to realize automatic positioning of the finishing tool, so that the finishing tool can accurately reach the processing area, thereby improving the processing efficiency.

[0062] It should also be noted that the end of the finishing knife 13 facing the porcelain insulator has a certain thickness so that the finishing knife will not directly enter the interior of the porcelain insulator when it is in contact with the side wall of the porcelain insulator.

[0063] In this embodiment, as a further optimized solution, please refer to Figure 2 , Figure 4 and Fig.12 , storage boxes 15 are provided on both sides of the bracket 14, and a winding rod 47 is rotatably provided in the inner cavity of the two storage boxes 15 (a spring is provided between the winding rod 47 and the storage box 15), and a flexible support plate 48 (such as a flexible plastic material) is wound on the outer wall of the winding rod 47, and a third magnetic block 49 is provided at the end of the flexible support plate 48 away from the winding rod 47, and the third magnetic block 49 is located on the outside of the storage box 15, and a driving device (such as an electric cylinder) is provided on the bracket 14; the electric cylinder drives the third magnetic block 49 to move, so that the third magnetic blocks 49 on both sides are close to each other and adsorbed, and the flexible support plate 48 wound on the outer wall of the winding rod 47 is pulled out to collect debris generated during the fine finishing process.
