Description

Technical Field

[0001] This invention relates to the field of insulator forming and processing technology, and in particular to a forming and processing equipment and method for power porcelain insulators. Background Technology

[0002] Porcelain insulators are core insulating components supporting the construction of new power systems in strategic emerging industries. They consist of porcelain parts, steel caps, and steel feet. Their core function is to support conductors and provide insulation between conductors and ground, preventing current leakage and ensuring the safe operation of high-voltage and ultra-high-voltage lines. During processing, raw materials such as quartz and feldspar are first ground and purified, and vacuum-refined to remove air bubbles. After being molded and shaped, they are finished. With their excellent performance, these components are adapted to emerging demands such as new energy grid connection and ultra-high-voltage power transmission. They are not only an important manifestation of the high-end development of power equipment, but also lay a solid foundation for the green and low-carbon development of strategic emerging industries.

[0003] For example, Chinese Patent CN119694690B discloses a molding and processing equipment and method for electric porcelain insulators, including a spinning forming machine, a waste blank conveyor, a spinning blank seat, and a blank trimming knife assembly. The above device combines the spinning forming machine with the waste blank conveyor to trim the rotating blank and output the excess blank. It adopts a blank center trimming mechanism design, adding a hollow outer cylinder and a hollow inner cylinder at the upper end of the central conical cutter. With the help of the material conveying assembly, the waste material that surges out from the contact between the central conical cutter and the blank is stored and automatically output. Furthermore, the setting of the spinning blank anti-falling assembly can ensure that the upward-flowing waste material will not fall again, preventing it from affecting the center collapse of the electric porcelain insulator and avoiding secondary blockage of the central conical cutter outlet. However, it still has significant shortcomings when facing diverse production needs. Due to the large differences in the size of the center hole to be processed for different specifications of power porcelain insulator blanks, the existing blank center dressing machine usually requires frequent replacement of the center conical cutter. This traditional replacement method is cumbersome, time-consuming and labor-intensive, which seriously reduces production efficiency. More importantly, frequent disassembly and assembly can easily lead to a decrease in the accuracy of the cutter installation, resulting in positioning deviation or unstable installation, which in turn directly affects the subsequent dressing quality of the blank center hole, and may even cause the blank to be scrapped. Therefore, it is urgent to improve it. Summary of the Invention

[0009] Furthermore, the prompting mechanism includes a linkage rod, which is fixedly connected to the rack on the side away from the linkage plate. One side of the linkage rod slides out of the frame and is fixedly connected to a prompting plate. There are three prompting plates.

[0010] Furthermore, an optical fiber sensor is fixedly connected to the side of the frame near the mounting base, and a light-shielding plate is provided on one side of the top of the mounting base.

[0012] Furthermore, the second engagement / disengagement mechanism includes a connecting seat, which is fixedly connected to the bottom end of the lifting rod. A connecting block is inserted into the interior of the connecting seat, and the connecting block is fixedly connected to one side of the assembly plate located at the center of the blank dressing machine.

[0013] Furthermore, the lifting mechanism includes a mounting frame, which is fixedly connected to the top center of the frame. A third motor is fixedly connected to the top of the mounting frame, and a second screw is fixedly connected to the output end of the third motor.

The lifting block is slidably connected to the slide rods, and one side of the lifting block is fixedly connected to one side of the lifting rod.

[0014] A method for forming and processing electrical porcelain insulators includes the following steps: Step 1: Place the electric porcelain insulator blank, which has been ground, purified, vacuum-refined, and molded, stably on the spinning base of the machine. The blank is fixed by the positioning structure of the spinning base to ensure that the blank does not shift during rotation. At the same time, the processing parameters are preset by the controller, including the blank center hole specifications, blank trimming speed and lifting mechanism stroke, etc., to complete the pre-processing preparation. Step 2: The controller starts the repositioning mechanism according to the preset center hole specifications. The first motor drives the worm gear to rotate, and the worm gear meshes with the worm wheel and shaft to rotate. The gear on the shaft rotates synchronously and meshes with the rack. The rack drives the linkage plate to slide smoothly along the guide frame. The guide block cooperates with the guide frame to ensure the stability of the movement. When the corresponding specification billet center trimmer moves to the processing station with the mounting base, the light shield on the mounting base triggers the fiber optic sensor on the frame. The sensor feeds back a signal to the controller, and the repositioning mechanism stops running. At the same time, the linkage rod drives the corresponding indicator plate to the position of the observation window of the mounting cover, so that the operator can confirm the specifications of the billet center trimmer and complete the switching and positioning of the billet center trimmer. Step 3: Start the lifting mechanism. The third motor drives the second screw to rotate, causing the lifting block to descend along the two side slides, so that the connecting seat at the bottom of the lifting rod aligns with the connecting block on the assembly plate. Then, the second engagement and disengagement mechanism is activated, and the electric push rods on both sides push the second positioning block to insert into the second positioning hole of the connecting block, locking the billet center trimmer with the lifting rod. Then, the first engagement and disengagement mechanism is activated, and the second motor drives the first screw to rotate, causing the screw block and the first positioning block to exit the first positioning hole of the docking block, releasing the mechanical connection between the assembly plate and the mounting base. The lifting mechanism rises again, lifting the billet center trimmer off the mounting base and moving it to the preset height directly above the billet turning base. Step 4: Start the billet rotating stand to drive the billet to rotate at high speed. At the same time, the lifting mechanism slowly descends, so that the central conical cutter of the billet center trimmer accurately contacts the end face of the billet and performs center hole cutting trimming according to the preset stroke. During the trimming process, the trimming cutter group works together to perform synchronous trimming on the outer periphery of the billet to ensure that the overall size of the billet meets the standard. At the same time, relying on the automatic control of the equipment, tool deviation or billet damage caused by manual intervention is avoided. Step 5: After the center hole is finished, the lifting mechanism drives the billet center trimming machine to rise and reset. The first engagement and disengagement mechanism operates again, and the second motor drives the first screw in the reverse direction, so that the first positioning block is inserted into the first positioning hole of the docking block, and the assembly plate and the mounting base are locked again. Then the electric push rod of the second engagement and disengagement mechanism retracts, the second positioning block exits the second positioning hole, the connection between the lifting rod and the assembly plate is released, the lifting mechanism drives the lifting rod to rise to the initial position, the billet rotating seat stops rotating, the finished billet is taken out, and a single processing cycle is completed. Step 6: If different specifications of billets need to be processed, repeat steps 2 to 5 to achieve automatic switching of the billet center dressing machine, without the need for manual handling of the heavy billet center dressing machine.

[0015] Compared with the prior art, the beneficial effects of the present invention are: Firstly, in this invention, a repositioning mechanism is installed on the frame. Multiple mounting seats slide on one side of the frame via the repositioning mechanism, and each mounting seat is connected to an assembly plate on one side. Different types of blank center dressing machines are installed on the assembly plates, and the selection and adjustment are made according to processing requirements. When different specifications of power porcelain insulator blanks need to be processed, the repositioning mechanism can drive the rack to move the linkage plate, thereby accurately transporting the blank center dressing machine of the corresponding specification to the processing station. This design realizes the rapid switching of multiple specifications of tools, completely solving the problems of low efficiency and reduced installation accuracy caused by frequent tool disassembly and assembly in traditional equipment. This equipment can flexibly adapt to the diversified and high-precision production needs of power porcelain insulators in strategic emerging industries such as ultra-high voltage and new energy grid connection, greatly improving the automation level of the production line and providing strong support for the high-end manufacturing of power equipment.

[0016] Secondly, in this invention, by setting a first and a second engagement / disengagement mechanism, when the billet center trimming machine needs maintenance or replacement, the first engagement / disengagement mechanism can release the lock between the assembly plate and the mounting base, while the lifting mechanism moves the boom. The second engagement / disengagement mechanism then locks the assembly plate and the boom, allowing for quick replacement. During installation, the lifting mechanism lowers, the first engagement / disengagement mechanism locks, and the second engagement / disengagement mechanism releases, completing the preparatory work before replacement. This combination of dual engagement / disengagement structures enables fully automatic and rapid loading and unloading of the tool module, eliminating the need for manual handling of heavy tools, reducing labor intensity, and further ensuring the operational stability of the equipment.

[0027] A method for forming and processing electrical porcelain insulators includes the following steps: Step 1: The electric porcelain insulator blank, which has been ground, purified, vacuum-refined, and molded, is placed stably on the spinning base 5 of the machine base 1. The blank is fixed by the positioning structure of the spinning base 5 to ensure that the blank does not shift during rotation. At the same time, the processing parameters are preset by the controller 3, including the blank center hole specifications, blank trimming speed and the stroke of the lifting mechanism 15, etc., to complete the pre-processing preparation. Step 2: According to the preset center hole specifications, the controller 3 starts the repositioning mechanism 8. The first motor 861 drives the worm gear 862 to rotate. The worm gear 862 meshes with and drives the worm wheel 863 and the shaft 864 to rotate. The gear 81 on the shaft 864 rotates synchronously and meshes with the rack 82. The rack 82 drives the linkage plate 83 to slide smoothly along the guide frame 85. The guide block 84 cooperates with the guide frame 85 to ensure the stability of movement. When the corresponding specification billet center trimming machine 6 moves to the processing station with the mounting base 12, the light shield 11 on the mounting base 12 triggers the fiber optic sensor 10 on the frame 2. The sensor feeds back a signal to the controller 3, and the repositioning mechanism 8 stops running. At the same time, the linkage rod 91 drives the corresponding indicator plate 92 to move to the position of the observation window 94 of the mounting cover 93, so that the operator can confirm the specifications of the billet center trimming machine 6 and complete the switching and positioning of the billet center trimming machine 6. Step 3: Start the lifting mechanism 15. The third motor 152 drives the second screw 153 to rotate, causing the lifting block 154 to descend along the two side slides 155, so that the connecting seat 141 at the bottom of the hanging rod 16 docks with the connecting block 142 on the assembly plate 7. Then the second engagement and disengagement mechanism 14 is activated, and the electric push rods 143 on both sides push the second positioning block 144 to insert into the second positioning hole 145 of the connecting block 142, locking the billet center trimming machine 6 with the hanging rod 16. Then the first engagement and disengagement mechanism 13 is activated, and the second motor 137 drives the first screw 136 to rotate, causing the screw block 135 and the first positioning block 134 to exit the first positioning hole 133 of the docking block 132, releasing the mechanical connection between the assembly plate 7 and the mounting base 12. The lifting mechanism 15 rises again, lifting the billet center trimming machine 6 away from the mounting base 12 and moving it to a preset height directly above the billet turning base 5. Step 4: Start the billet holder 5 to drive the billet to rotate at high speed. At the same time, the lifting mechanism 15 slowly descends so that the central conical cutter of the billet center trimmer 6 accurately contacts the end face of the billet and performs center hole cutting trimming according to the preset stroke. During the trimming process, the trimming cutter group 4 works together to perform synchronous trimming on the outer periphery of the billet to ensure that the overall size of the billet meets the standard. At the same time, relying on the automatic control of the equipment, tool deviation or billet damage caused by manual intervention is avoided. Step 5: After the center hole is finished, the lifting mechanism 15 drives the billet center trimming machine 6 to rise and reset. The first engagement and disengagement mechanism 13 operates again, and the second motor 137 drives the first screw 136 in the reverse direction, so that the first positioning block 134 is inserted into the first positioning hole 133 of the docking block 132, and the assembly plate 7 and the mounting base 12 are locked again. Then, the electric push rod 143 of the second engagement and disengagement mechanism 14 retracts, the second positioning block 144 exits the second positioning hole 145, the connection between the lifting rod 16 and the assembly plate 7 is released, the lifting mechanism 15 drives the lifting rod 16 to rise to the initial position, the billet rotating seat 5 stops rotating, the finished billet is taken out, and the single processing cycle is completed. Step 6: If different specifications of billets need to be processed, repeat steps 2 to 5 to achieve automatic switching of the billet center trimmer 6, without the need for manual handling of the heavy billet center trimmer 6.
