Description

Technical Field

[0001] This invention relates to the field of insulator processing tooling technology, specifically to an automatic magnetic casting device for high-strength porcelain insulators of high-voltage fuses. Background Technology

[0002] Insulators are core insulating components in power transmission and distribution lines. Their production process requires the porcelain column and matching metal fittings to be integrally formed through a casting process. The conventional insulator casting process consists of multiple steps, including middle casting and end casting. During processing, the porcelain column and various fittings are placed on special tooling, and the casting and filling of each position are completed in sequence. After the casting material has solidified, the finished workpiece is removed. The entire processing flow includes continuous operation steps such as workpiece placement, positioning, multi-station casting, and finished product unloading.

[0003] Patent CN222690444U discloses a shaping device for gluing porcelain insulators. The device has a base with a horizontally sliding placement frame. The bottom of the placement frame is locked to the base through a magnetic plug-in structure. The insulator is supported by the placement groove on the top of the placement frame. With the help of the positioning side plate, the fittings that penetrate the insulator are limited. The device can only complete the static shaping and positioning of the insulator after gluing.

[0004] The above-mentioned device can only maintain the insulator in a single static position. To complete all the middle and end pouring processes, it is necessary to disassemble and reassemble the workpiece multiple times and manually flip the workpiece. The entire processing process involves many manual operation steps, and the processing time for a single product is long. When producing in batches, the overall processing efficiency is low. Summary of the Invention

[0005] To address the aforementioned issues, an automatic magnetic casting device for high-strength porcelain insulators of high-voltage fuses is provided. This device uses magnetic attraction to fix the fittings and a rotatable turntable to change the orientation of the porcelain column. This changes the traditional operation mode of repeatedly clamping and manually flipping the workpiece, thereby effectively improving the production efficiency of insulator casting.

[0006] To address the problems of existing technologies, this invention provides an automatic magnetic casting device for high-strength porcelain insulators in high-voltage fuses, comprising a frame, two turntables, a positioning frame, two fixing frames, an adjustment and fixing structure, and a clamping structure. The two turntables are coaxial and rotatably mounted on the frame. The two ends of the positioning frame are respectively connected to the two turntables.

The two fixing frames are arranged parallel to each other on both sides of the positioning frame and are connected to the two turntables. Each fixing frame has multiple positioning slots corresponding to the casting stations. These positioning slots are used to place the ends of the porcelain column, and each positioning slot is equipped with a second magnet for magnetically attracting the end fittings of the porcelain column. Multiple adjustment and fixing structures are respectively located at the casting stations of the positioning frame. These adjustment and fixing structures are used to adjust and fix the placement state of the central fitting. The clamping structure is used to clamp and fix the porcelain column onto the positioning slots.

[0007] Preferably, the adjustment and fixing structure includes an adjustment plate that can move in a direction perpendicular to itself. The adjustment plate is provided with two mating blocks that correspond to the two mounting holes on the central fitting, and the ends of the mating blocks are provided with guide surfaces.

[0008] Preferably, the adjustment and fixing structure further includes a rotation switching assembly, which includes a fixed base and a rotating arm assembly; the fixed base is disposed on the positioning frame; the rotating arm assembly is rotatably disposed on the fixed base, and the rotating arm assembly is connected to the adjustment plate.

[0009] Preferably, the rotating arm assembly includes a rotating sleeve, a rotating shaft, and a slider; the rotating sleeve is rotatably connected to the fixed base; the rotating shaft is coaxial with and slidably connected to the rotating sleeve, and an axial groove is provided on the rotating shaft; the slider is installed on the inner wall of the rotating sleeve, and the slider is slidably disposed in the groove.

[0010] Preferably, the rotating arm assembly further includes a tapered grip and a return spring; the tapered grip is disposed at one end of the rotating shaft; and the return spring is disposed at the other end of the rotating shaft.

[0011] Preferably, the outer wall of the rotating sleeve has two symmetrically formed abutment grooves, and one side of the rotating sleeve is provided with an abutment component that abuts against the outer wall of the rotating sleeve.

[0012] Preferably, the clamping assembly includes a bracket, a guide rod, and a clamping block assembly; the bracket is disposed on the fixed base; the guide rod is used to movably connect the bracket and the clamping block assembly; the clamping block assembly is used to clamp the rotating sleeve.

[0013] Preferably, the clamping block assembly includes a roller assembly and two third magnets; the roller assembly is tangent to the rotating shaft and connected to the guide rod; the two third magnets are used to provide a repulsive force to push the roller assembly against the rotating shaft.

[0014] Preferably, the clamping structure includes two clamping units, which are respectively disposed on the two fixing frames. The clamping units are used to provide a clamping force on the ceramic column toward the fixing frame.

[0015] Preferably, the frame is further provided with a rotation switching mechanism and a positioning mechanism; the rotation switching mechanism is used to drive the turntable to rotate; the positioning mechanism is used to fix the turntable.

[0016] The advantages of this invention compared to the prior art are:

[0017] 1. This invention comprises a frame, two coaxial turntables, a positioning frame, two fixed frames, an adjustment and fixing structure, and a clamping structure. During the casting operation, both ends of the ceramic column are placed in the positioning slots of the fixed frames. The second magnet in the positioning slots fixes the end fittings, and the clamping structure clamps and fixes the ceramic column. Then, one end of the middle fitting is attached to the positioning frame, and the middle fitting is initially positioned by magnetic attraction using the first magnet. The middle fitting is then locked in position by the adjustment and fixing structure. After the middle fitting is cast and solidified, the turntable rotates 90 degrees and 180 degrees sequentially to switch positions and complete the casting of the fittings at both ends. This casting device fixes the fittings by magnetic attraction, and the rotatable turntable completes the reversal of the ceramic column. It changes the traditional operation mode of repeatedly clamping and manually flipping the workpiece, making the operation process simpler and thus effectively improving the production efficiency of insulator casting.

[0018] 2. This invention includes an adjustment plate and a docking block with a guide surface on the adjustment plate. After the central fitting is magnetically attracted and positioned by the first magnet, the worker pushes the adjustment plate closer to the central fitting, causing the docking block to be inserted into the mounting hole of the central fitting. When the fitting is misaligned, the guide surface at the end of the docking block can push the fitting to move slightly to correct the deviation. At the same time, the docking block can restrict the rotation of the central fitting during casting. After the docking block is fitted and engaged with the mounting hole, it works with the first magnet to lock the central fitting. There is no need for repeated manual correction of the fitting position, which makes up for the lack of accuracy of single magnetic attraction positioning and avoids casting misalignment defects, thereby improving the positioning accuracy of the central fitting.

[0019] 3. In this invention, the fixed base and rotating arm assembly have an adjustment plate positioned above the positioning frame before the ceramic column is placed, leaving operating space for easy placement of the central hardware. After the central hardware is placed, the rotating arm assembly is rotated around the fixed base, causing the adjustment plate to turn towards the central hardware, and then the adjustment plate is pushed closer to the hardware to complete the positioning and fixing. After the casting operation is completed, the adjustment plate is first retracted to detach from the central hardware, and then the rotating arm assembly is rotated in the opposite direction to reset the adjustment plate to above the positioning frame, eliminating component obstruction and facilitating the removal of the finished product by the operator. The working position of the adjustment plate can be switched using the rotating arm assembly, thereby improving the ease of operation for workpiece loading, unloading and positioning.

[0033] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0034] Reference Figures 1 to 12The diagram shows an automatic magnetic casting device for high-strength porcelain insulators used in high-voltage fuses. It includes a frame 1, two turntables 2, a positioning frame 3, two fixing frames 4, an adjustment and fixing structure 5, and a clamping structure 6. The two turntables 2 are coaxial and rotatably mounted on the frame 1. The two ends of the positioning frame 3 are connected to the two turntables 2 respectively. The positioning frame 3 has multiple casting stations, and each casting station is equipped with a first magnet 31 for magnetically attracting the central fitting of the porcelain column. The two fixing frames 4 are arranged parallel to each other on both sides of the positioning frame 3. The fixing frame 4 is connected to the two turntables 2. The fixing frame 4 is provided with multiple positioning slots 41 corresponding to the pouring positions. The positioning slots 41 are used to place the ends of the ceramic columns, and each positioning slot 41 is provided with a second magnet 42 for magnetically attracting the hardware at the ends of the ceramic columns. There are multiple adjustment and fixing structures 5, which are respectively set on the pouring positions of the positioning frame 3. The adjustment and fixing structures 5 are used to adjust and fix the placement state of the middle hardware. The clamping structure 6 is used to clamp and fix the ceramic columns on the positioning slots 41.

[0035] After the pouring operation begins, first place both ends of the ceramic column into the positioning slots 41 of the two fixing frames 4, and then use the clamping structure 6 to clamp the ceramic column, fixing it in the positioning slots 41. Next, insert one end of the central fitting into the central pouring cavity of the ceramic column, and attach the other end of the central fitting to the positioning frame 3. At this time, the first magnet 31 on the pouring station attracts the central fitting, completing the initial positioning. The second magnet 42 in the positioning slot 41 also simultaneously attracts the end fitting, assisting in the end alignment. After the ceramic column and fitting are in place, operate the corresponding adjusting fixing structure 5 of the central fitting to fine-tune and lock the posture of the central fitting, preventing displacement during pouring. After the central pouring is completed and the material has dried and solidified, rotate the turntable 90 degrees to make one end of the ceramic column vertically upward, and pour the fitting at that end; after this end solidifies, rotate the turntable 2 180 degrees to make the other end of the ceramic column face upward, completing the pouring of the other end. This casting device uses magnetic attraction to fix the fittings, and works with a rotatable turntable 2 to change the direction of the porcelain column. This changes the traditional operation mode of repeatedly clamping and manually flipping the workpiece, making the operation process simpler and thus effectively improving the production efficiency of insulator casting.

[0036] Reference Figure 4 As shown: The adjustment and fixing structure 5 includes an adjustment plate 51, which can move in a direction perpendicular to itself. The adjustment plate 51 is provided with two docking blocks 511 corresponding to the two mounting holes on the central fitting. The ends of the docking blocks 511 are provided with guide surfaces.

[0037] Once the central fitting is magnetically attached to the positioning frame 3, the worker pushes the adjusting plate 51 forward, bringing it closer to the central fitting of the ceramic column. This aligns the two mating blocks 511 on the adjusting plate 51 with and inserts them into the mounting holes of the central fitting. If the central fitting is misaligned, the guide surfaces at the ends of the mating blocks 511 will guide it. When the mating blocks 511 contact the mounting holes, they will slightly move the fitting, correcting any positional deviations during placement. Simultaneously, the two mating blocks 511, once engaged in the mounting holes, also prevent the fitting from rotating during the pouring process. After the adjusting plate 51 is moved to align with the central fitting, the mating blocks 511 are fully inserted into the mounting holes, their outer walls perfectly fitting the inner walls of the mounting holes. Combined with the first magnet 31 on the positioning frame 3, the central fitting is then secured. The position is automatically corrected by the guide surface of the docking block 511, eliminating the need for staff to repeatedly move the hardware to find the correct position. This makes up for the accuracy shortcomings of relying solely on magnetic positioning and effectively avoids problems such as casting misalignment caused by hardware offset, thereby improving the positioning accuracy of the central hardware.

[0038] Reference Figure 3 , Figure 4 and Figure 5 As shown: The adjustment and fixing structure 5 further includes a rotation switching assembly, which includes a fixed base 52 and a rotating arm assembly 53; the fixed base 52 is disposed on the positioning frame 3; the rotating arm assembly 53 is rotatably disposed on the fixed base 52, and the rotating arm assembly 53 is connected to the adjustment plate 51.

[0039] Before placing the ceramic column, the adjusting plate 51 rests above the positioning frame 3, leaving ample operating space for workers to place the central fitting. After the central fitting is in place, the positioning operation begins. Workers operate the rotating arm assembly 53, causing it to rotate around the fixed base 52, simultaneously turning the adjusting plate 51 to the position of the central fitting. Once aligned, the adjusting plate 51 is pushed closer to the central fitting, completing the positioning and fixing of the fitting. After the casting process is completed, the adjusting plate 51 is first retracted, detached from the central fitting, and then the rotating arm assembly 53 is rotated in the opposite direction, returning the adjusting plate 51 to above the positioning frame 3. At this point, there are no components obstructing the finished product, and the adjusting plate 51 will not interfere with the operator's hand movements throughout the entire process of placing and removing the workpiece. The placement of the fitting and the removal of the insulator are not hindered by any components.

[0040] Reference Figure 5 , Figure 6 and Figure 7As shown: The rotating arm assembly 53 includes a rotating sleeve 521, a rotating shaft 522, and a slider 523; the rotating sleeve 521 is rotatably connected to the fixed base 52; the rotating shaft 522 is coaxial with and slidably connected to the rotating sleeve 521, and the rotating shaft 522 has an axial groove 5221; the slider 523 is installed on the inner wall of the rotating sleeve 521, and the slider 523 is slidably disposed in the groove 5221.

[0041] When the rotating shaft 522 rotates, it drives the connected adjusting plate 51 to rotate synchronously, and through the cooperation of the slider 523 and the slide groove 5221, it drives the rotating sleeve 521 to rotate synchronously. When it is necessary to move the adjusting plate 51 back and forth, simply push or pull the rotating shaft 522, and the rotating shaft 522 can slide along the axial direction of the rotating sleeve 521. At this time, the slider 523 slides along the slide groove 5221 without obstructing the movement of the rotating shaft 522. Through the cooperation of the rotating sleeve 521, the rotating shaft 522, and the slider 523, the rotating shaft 522 can simultaneously have two motion modes: rotation and linear sliding. The rotational motion is used to switch the position of the adjusting plate 51, and the sliding motion is used to complete the hardware docking and positioning. The two motions are independent of each other and do not interfere with each other, thereby realizing the motion state of the rotating arm assembly 53 adapting to the adjusting plate 51.

[0042] Reference Figure 4 and Figure 6 As shown: The rotating arm assembly 53 further includes a tapered grip 524 and a return spring 525; the tapered grip 524 is disposed at one end of the rotating shaft 522; the return spring 525 is disposed at the other end of the rotating shaft 522.

[0043] When adjusting the adjusting plate 51 to align with the fitting, the operator first holds the conical handle 524 and then applies axial tension to the rotating shaft 522. During the movement of the rotating shaft 522, it needs to overcome the resistance of the return spring 525 and slide along the axial direction of the rotating shaft 522, simultaneously moving the adjusting plate 51. Once the adjusting plate 51 aligns with the fitting, the operator removes the grip on the conical handle 524. The force generated by the return spring 525 is then transmitted through the adjusting plate 51 to the central fitting, making a small adjustment to the fitting's position. The conical handle 524 facilitates manual operation of the components, while the return spring 525, while automatically resetting, can also use its own elasticity to make minor adjustments to the fitting, thus eliminating the need for manual correction of the central fitting's position.

[0044] Reference Figure 5 and Figure 8 As shown: The outer wall of the rotating sleeve 521 has two symmetrically formed abutment grooves 5211, and one side of the rotating sleeve 521 is provided with abutment component 54 that abuts against the outer wall of the rotating sleeve 521.

[0045] When the adjusting plate 51 is positioned above the positioning frame 3, the clamping component 54 engages with one of the abutment grooves 5211. The engagement of the abutment component with the abutment groove 5211 prevents the rotating sleeve 521 from rotating. When it is necessary to rotate the adjusting plate 51 to align with the fitting, the rotating shaft 522 is rotated, and simultaneously the clamping component 54 disengages from the abutment groove 5211. After unlocking, the rotating sleeve 521 and rotating shaft 522 can rotate normally. Once the adjusting plate 51 is aligned with the central fitting, the clamping component 54 engages with the other abutment groove 5211, securing the rotating sleeve 521 again. At this point, the rotating sleeve 521 cannot rotate, the rotating shaft 522 can only slide axially, and the adjusting plate 51 can only move linearly, successfully completing the fitting position adjustment. By the correspondence between the clamping component 54 and the two engaging grooves in different states, the attitude constraint of the adjusting plate 51 is achieved, thereby preventing the adjusting plate 51 from deflecting due to gravity in the standby state.

[0046] Reference Figure 8 As shown: The clamping assembly 54 includes a bracket 541, a guide rod 542, and a clamping block assembly 543; the bracket 541 is disposed on the fixed base 52; the guide rod 542 is used to movably connect the bracket 541 and the clamping block assembly 543; the clamping block assembly 543 is used to clamp the rotating sleeve 521.

[0047] When the equipment is in standby mode, the clamping block assembly 543 is pressed against the outer wall of the rotating sleeve 521 and engaged in the abutment groove 5211, restricting the rotation of the rotating sleeve 521 and preventing the adjustment plate 51 from shifting. When the operator rotates the rotating sleeve 521 to change the position of the adjustment plate 51, the outer wall of the rotating sleeve 521 will press against the clamping block assembly 543, causing the guide rod 542 to retract slightly in sync, allowing the clamping block assembly 543 to disengage from the abutment groove 5211. After the rotating sleeve 521 is unlocked, it can rotate normally. When the adjustment plate 51 rotates to the position aligned with the central hardware, the clamping block assembly 543 re-engages in the corresponding abutment groove 5211, again limiting the rotation of the rotating sleeve 521 and preventing it from rotating. During the locking and unlocking process of the rotating sleeve 521, the clamping block assembly 543 automatically retracts and resets its position, requiring no manual operation throughout the process, thus enabling the clamping assembly 543 to automatically complete the unlocking and locking actions.

[0048] Reference Figure 8 and Figure 9 As shown: The clamping block assembly 543 includes a roller assembly 5431 and two third magnets 5432; the roller assembly 5431 is tangent to the rotating shaft 522 and is connected to the guide rod 542; the two third magnets 5432 are used to provide a repulsive force to push the roller assembly 5431 against the rotating shaft 522.

[0049] In the limited position, the roller assembly 5431 is pressed tightly against the rotating shaft 522 and engaged in the abutment groove 5211, thereby locking the rotating sleeve 521 and keeping the adjusting plate 51 in a fixed position, preventing it from wobbling. The two third magnets 5432 continuously generate repulsive force, pushing the roller assembly 5431 tightly against the rotating shaft 522, ensuring the limited position remains secure. When switching workstations, the operator rotates the rotating shaft 522, and power is simultaneously transmitted to the rotating sleeve 521. The rotating sleeve 521 overcomes the frictional resistance between the roller assembly 5431 and the abutment groove 5211, pushing the roller assembly 5431 out of the abutment groove 5211. After unlocking, the rotating sleeve 521 can rotate. When the adjusting plate 51 rotates to the position aligned with the central hardware, the roller assembly 5431, under the repulsive force of the third magnets 5432, re-engages in the corresponding abutment groove 5211, locking the rotating sleeve 521 again. With the repulsive force continuously provided by the third magnet 5432, the roller assembly 5431 can always adhere to the outer wall of the rotating shaft 522, and can automatically fit into the abutment groove 5211 to lock after each rotation switch.

[0050] Reference Figure 1 , Figure 2 and Figure 10 As shown: The clamping structure 6 includes two clamping units 61, which are respectively disposed on the two fixing frames 4. The clamping units 61 are used to provide clamping force to the ceramic column toward the fixing frame 4.

[0051] The clamping unit 61 includes a rotating shaft 611, multiple connecting rods 612, a pressure plate 613, and multiple clamping springs 614. The rotating shaft 611 is arranged parallel to the fixed frame 4, and the rotating shaft 611 and the fixed frame 4 are rotatably connected through a bearing seat. The multiple connecting rods 612 are equally spaced on the rotating shaft 611. The pressure plate 613 is slidably connected to the multiple connecting rods 612. The multiple clamping springs 614 are respectively sleeved on the multiple connecting rods 612. The clamping springs 614 are used to provide the pressure plate 613 with a thrust toward the fixed frame 4.

[0052] After all the ceramic columns are placed on the casting device, the two sets of clamping units 61 are activated. Initially, the connecting rods 612 and pressure plates 613 in the clamping unit 61 are below the fixing frame 4. When clamping the ceramic column, a force is first applied to the pressure plate 613 away from the rotating shaft 611, causing the pressure plate 613 to move along the connecting rod 612 against the force of the clamping spring 614. This increases the distance between the pressure plate 613 and the rotating shaft 611. Then, the pressure plate 613 is driven to rotate around the axis of the rotating shaft 611, and the multiple connecting rods 612 on the rotating shaft 611 rotate synchronously. When the pressure plate 613 is directly above the ceramic column, the force on the pressure plate 613 is slowly removed. The clamping spring 614 pushes the pressure plate 613 towards the ceramic column, causing the pressure plate 613 to press against the ceramic column, confining the ceramic column inside the positioning groove 41. The two clamping units 61 operate symmetrically, ensuring that the ceramic column is subjected to uniform force at both ends, effectively preventing the ceramic column from shifting or flipping during the rotation of the turntable 2 and the pouring operation, thereby preventing the ceramic column from displacing during the operation.

[0053] Reference Figure 1 , Figure 2 , Figure 11 and Figure 12 As shown: The frame 1 is also provided with a rotation switching mechanism 7 and a positioning mechanism 8; the rotation switching mechanism 7 is used to drive the turntable 2 to rotate; the positioning mechanism 8 is used to fix the turntable 2.

[0054] Specifically, the rotary switching mechanism 7 includes a drive gear 71, a driven gear 72, and a rotary driver 73. The drive gear 71 and the driven gear 72 mesh with each other. The drive gear 71 is connected to the rotary driver 73, and the driven gear 72 is connected to the turntable 2. The positioning mechanism 8 includes a synchronous disk 81, a insertion rod 82, and a linear driver 83. The synchronous disk 81 is coaxially connected to the turntable 2. Three docking holes 811 are provided on the circumferential wall of the synchronous disk 81. The linear driver 83 is used to drive the insertion rod 82 to insert into the docking holes 811.

[0055] Once the central fittings are poured, the rotary switching mechanism 7 and positioning mechanism 8 on frame 1 can be activated to switch the pouring position. The rotary driver 73 in the rotary switching mechanism 7 drives the drive gear 71, and the driven gear 72, meshing with the drive gear 71, rotates accordingly, thereby driving the coaxial turntable 2 to rotate. The turntable 2 synchronously drives the positioning frame 3, the fixing frame 4, the ceramic column, and the fittings to rotate synchronously, sequentially switching the pouring positions at both ends. When the turntable 2 rotates to the preset pouring angle, the rotary switching mechanism 7 stops working, and the positioning mechanism 8 begins operating. The linear driver 83 in the positioning mechanism 8 pushes the insertion rod 82 forward, inserting the insertion rod 82 into the corresponding docking hole 811 on the outer wall of the synchronous disc 81. The synchronous disc 81 and the turntable 2 are coaxially connected, and the engagement of the insertion rod 82 with the docking hole 811 locks the turntable 2, preventing it from rotating during the pouring process. Through the coordinated operation of the rotary switching mechanism 7 and the positioning mechanism 8, the rotation angle and stopping position of the turntable 2 can be controlled.

[0056] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
