Description

Technical Field

[0001] This utility model relates to the field of suspension insulator processing, and in particular to a device for uniformly glazing the head of a suspension insulator. Background Technology

[0002] The uniform glazing device for suspension insulator heads achieves uniform glaze coverage, precise thickness control, and improved production efficiency through mechanical automation and precision control technology, thereby ensuring the electrical performance, mechanical strength, and long-term operational reliability of the insulators.

[0003] For example, the patent entitled "An Automatic Glazing Device for Suspended Porcelain Insulators" (patent application number: 202022025969.8) discloses an automatic glazing device for suspended porcelain insulators. By moving the lever, the screw moves threadedly inside the support rod, allowing the screw to be adjusted in length. With the help of the top block set below, it is easy to fix the porcelain insulator on the tray and increase the stability during glazing. However, in actual use, when fixing porcelain insulators of different sizes, and because the inner diameters of different porcelain insulators are different, the device is fixed only by the top block, and the size of the top block cannot be adjusted. Therefore, the inner wall of the porcelain insulator cannot be made to abut against the outside of the top block during fixing. This makes the porcelain insulator prone to shaking and displacement when the tray rotates, thus affecting the subsequent glazing effect.

[0004] Therefore, it is necessary to propose a device for uniformly glazing the head of a suspension insulator to solve the above problems. Utility Model Content

[0022] This utility model provides, for example Figures 1-4 The device shown is a uniform glazing device for the head of a suspension insulator. It aims to solve the problem in the existing automatic glazing device for suspension porcelain insulators where the size of the top block cannot be adjusted and the fixing of porcelain insulators with different inner diameters is not stable, which affects the glazing effect. By optimizing the positioning structure and glazing mechanism, uniform glazing of the insulator head is achieved.

[0023] The workbench 1 serves as the supporting base of the device. The upper surface is fixedly connected to the isolation door 2, the multi-axis robotic arm 5, and the high-pressure pump 7. The lower surface is equipped with the glaze tank 4, the drive motor 91, and the detachable waste cylinder 10. The workbench is provided with a waste trough 11, and the bottom of the trough has a discharge hole corresponding to the waste cylinder 10 for collecting excess glaze.

[0024] Isolation door 2 is fixed to the top of workbench 1 to form a closed working space to prevent glaze splatter. Electric push rod 3 is fixed to the top.

[0025] The positioning mechanism 8 consists of a fixed disk 81, a servo motor 82, a trapezoidal screw 83, a movable sleeve 84, four sets of connecting rods 85, a push plate 86, a ball bearing 87, and a slider 88. The fixed disk 81 is connected to the output end of the electric push rod 3, and its axis corresponds to the axis of the placement disk 94. The servo motor 82 drives the trapezoidal screw 83 to rotate, which in turn drives the movable sleeve 84 to move along the screw axis. The movable sleeve 84 pushes the push plate 86 through the connecting rods 85, and the push plate 86 slides radially in the first through slot of the fixed disk 81 with the help of the slider 88. The push plate 86 has a built-in ball bearing 87, and the four sets of components are evenly distributed around the axis of the fixed disk 81.

[0026] The positioning mechanism 8 uses a servo motor 82 to drive the push plate 86 to extend and retract radially, adapting to the fixing requirements of insulators with different inner diameters. The four sets of evenly distributed push plates 86, together with the rolling balls 87, can ensure the fixing stability, reduce friction damage to the inner wall of the insulator, and avoid shaking during rotation.

[0027] The rotating placement mechanism 9 includes a drive motor 91, a first gear 92, a second gear 93, a placement disk 94, a conveying pipe 95, and a conveying pump 96. The drive motor 91 drives the placement disk 94 to rotate through the meshing of the first gear 92 and the second gear 93. The side wall of the placement disk 94 is provided with multiple slurry inlets. One end of the conveying pipe 95 is inserted into its central hole and rotatably connected, and the other end is connected to the glaze tank 4 through the conveying pump 96 to realize the glazing of the inner cavity of the insulator.

[0028] The placement plate 94 in the rotating placement mechanism 9 carries the insulator and rotates with the gear transmission to ensure uniform glazing; the material conveying pipe 95 cooperates with the material conveying pump 96 to deliver glaze slurry into the inner cavity of the insulator to achieve targeted glazing of the inner cavity.

[0029] The multi-axis robotic arm 5 is connected to the spray gun 6 via a flange at its end. The center point of the nozzle is located at the origin of the flange coordinate system, allowing for flexible adjustment of the position and angle of the spray gun 6.

[0030] One end of the high-pressure pump 7 is connected to the glaze tank 4, and the other end is connected to the spray gun 6 through the feed pipe, providing high-pressure glaze to the spray gun 6.

[0031] The multi-axis robotic arm 5 drives the spray gun 6 to achieve multi-dimensional movement. Combined with the pressure provided by the high-pressure pump 7, the glaze is precisely sprayed onto the outer surface of the insulator head to ensure the accuracy of the glaze position and thickness.

[0032] Waste tank 11 collects excess glaze slurry and guides it into waste cylinder 10 through discharge hole for centralized processing and recycling, keeping the working environment clean. Isolation door 2 isolates the working area to prevent glaze slurry from splashing and polluting the environment, thus improving operational safety.

[0033] During use, ensure the glaze slurry level in the glaze slurry tank 4 is sufficient, and that the waste material cylinder 10 is properly installed. Place the insulator to be glazed on the placement tray 94, ensuring its center is aligned with the axis of the placement tray 94. Activate the electric push rod 3 to lower the positioning mechanism 8 to a suitable position within the insulator's inner cavity. Activate the servo motor 82, causing the trapezoidal screw 83 to rotate and move the moving sleeve 84. This, along with the connecting rod 85, pushes the push plate 86 radially outward until the rolling ball 87 is tightly against the inner wall of the insulator, completing the fixing process. Then, turn off the servo motor 82 and activate the drive motor 91. The placement tray 94 rotates the insulator at a uniform speed, and simultaneously activates the material pump 96. The glaze slurry flows through the material pipe 95 and the placement tray 94... 4. The glaze enters the inner cavity of the insulator through the glaze inlet, completing the glazing of the inner cavity. The multi-axis robotic arm 5 and the high-pressure pump 7 are started. The high-pressure pump 7 pressurizes the glaze and delivers it to the spray gun 6. The robotic arm drives the spray gun 6 to spray the glaze onto the outer surface of the insulator head according to the preset trajectory, ensuring uniform coverage. After glazing is completed, the high-pressure pump 7, the multi-axis robotic arm 5, the drive motor 91 and the feed pump 96 are turned off in sequence (and the remaining glaze returns to the feed pipe 95 from the glaze inlet in the placement tray 94). The servo motor 82 is started to reverse, the push plate 86 is reset, the electric push rod 3 drives the positioning mechanism 8 to rise, the insulator is removed and placed in the designated area to dry. The waste cylinder 10 is disassembled to dispose of the collected excess glaze.
