Description

Technical Field

[0001] The present invention relates to the technical field of transformer insulation support blocks, and specifically to a positioning device and a positioning method for processing transformer insulation support blocks. Background Technique

[0002] As an electrical device for changing voltage, a transformer plays a crucial role in the power grid whether considered from the perspective of function or equipment value. The transformer coil constitutes the internal circuit of the device and is directly connected to the external power grid, being the most important component of the transformer. The support block is an important component in the assembly of each coil, providing both the circulation of transformer oil between the coils and ensuring the insulation distance.

[0003] When processing support blocks with relatively small sizes, simple jigs are usually used to position and press multiple support blocks. Manual operation of the jig is required, which is rather troublesome, and it is difficult to control the pressing force on the support blocks, resulting in affected stability. During machining, grooving operations are usually carried out, and unstable factors can lead to reduced machining accuracy, with the grooves on multiple support blocks showing uneven conditions, thus affecting subsequent use. Summary of the Invention

The L-shaped support plate is connected with a pressing mechanism one and a pressing mechanism two for pressing the insulation support blocks. The pressing mechanism one includes two moving plates, two inner pressing plates, a spring three, two wedge-shaped blocks, and multiple spring ones. The moving plates are movably connected to the L-shaped support plate. The spring three is used to drive the two moving plates away from each other.

The pressing mechanism two includes a side pressing plate, a pressing plate, multiple spring twos, and two driving grooves. The side pressing plate is movably connected to the processing table. The two ends of the spring two are connected to the side pressing plate and the pressing plate. The driving grooves are arranged on the side pressing plate and are matched with the wedge-shaped blocks. The bracket is connected with a driving mechanism for driving the side pressing plate to reciprocate.

[0006] Preferably, the first pressing mechanism further includes a guiding groove, a plurality of guiding columns, an upper pressing plate, and an inclined surface. The guiding groove is used for guiding the moving plate. The end of the guiding column is connected to the inner pressing plate, and the guiding column is slidably connected to the moving plate. The upper pressing plate is connected to the top of the moving plate, and the inclined surface is disposed on the upper pressing plate.

[0007] Preferably, the guiding groove is disposed on the L-shaped support plate. The moving plate is slidably connected to the guiding groove. The third spring is located in the guiding groove, and both ends of the third spring are connected to the moving plate.

[0008] Preferably, the second pressing mechanism further includes a plurality of sliding columns. The end of the sliding column is connected to the pressing plate, and the sliding column is slidably connected to the side pressing plate.

[0009] Preferably, the second spring is sleeved on the sliding column, and both ends of the second spring are connected to the pressing plate and the side pressing plate.

[0010] Preferably, the driving mechanism includes a cylinder, a dust suction hood, an L-shaped toothed plate, two pushing teeth, a main gear, a rotating shaft, two driven gears, two supporting seats, and two sliding grooves. The cylinder is connected to the bracket, and the power output end of the cylinder is connected to the dust suction hood. The end of the L-shaped toothed plate is connected to the dust suction hood, and the L-shaped toothed plate is matched with the main gear. The main gear is connected to the center of the rotating shaft. The driven gear is fixedly connected to the rotating shaft. The rotating shaft is rotatably connected to the supporting seat. The supporting seat is connected to the top of the L-shaped support plate. The end of the pushing tooth is connected to the side pressing plate. The driven gear is matched with the pushing tooth. The sliding groove is used for guiding the pushing tooth.

[0011] Preferably, the pushing tooth is meshed with the driven gear, and the pushing tooth is slidably connected to the sliding groove. The sliding groove is disposed on the top of the L-shaped support plate.

[0012] Preferably, an opening is disposed on the side surface of the dust suction hood, and a corrugated pipe is connected to the center of the top of the dust suction hood. The corrugated pipe is connected to a dust suction pipe, and the dust suction pipe is connected to a dust suction fan.

[0013] A positioning method for a positioning device used in the processing of transformer insulation spacers includes the following steps: Step 1: Place a plurality of insulation spacers on the L-shaped support plate. The cylinder drives the dust suction hood to move downward, synchronously driving the L-shaped toothed plate to move downward. The L-shaped toothed plate drives the main gear to rotate, synchronously driving the rotating shaft and the two driven gears to rotate. The driven gear drives the pushing tooth to move forward, thereby driving the side pressing plate to move forward, causing the wedge block to slide relative to the driving groove, driving the two moving plates to approach each other, and driving the two inner pressing plates to approach each other. At this time, the third spring is in a compressed state; Step 2: When the dust suction hood descends to an appropriate position, two inner pressing plates press against the front and rear ends of the insulating support block, the pressing plate presses against the side of the insulating support block, and two upper pressing plates press against the top edge of the insulating support block, achieving comprehensive locking and fixing of the insulating support block, improving the tightness of the connection of multiple insulating support blocks, facilitating subsequent machining. The dust suction hood timely sucks away the generated debris, reducing pollution to the L-shaped support plate, eliminating the need for manual cleaning. At the same time, the dust suction hood can reduce noise generation and reduce the splashing of debris, ensuring safe and reliable use; Step 3: After machining is completed, the cylinder drives the dust suction hood to move upward, making the dust suction hood away from the L-shaped support plate, leaving enough space for removing the insulating support block. The dust suction hood drives the L-shaped toothed plate to move upward, causing the main gear to rotate, synchronously driving the rotation of two driven gears, and two pushing teeth move backward synchronously, driving the side pressing plate to move backward, separating the pressing plate from the insulating support block. At the same time, the wedge block slides relative to the driving groove, and the compressed spring three drives the two moving plates to move away from each other, separating the inner pressing plates and the upper pressing plates from multiple insulating support blocks, realizing the loosening treatment of the insulating support block. At this time, the distance between the two upper pressing plates increases, facilitating the unloading operation.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention is provided with a pressing mechanism one, a pressing mechanism two, and a driving mechanism. The cylinder can drive the lifting of the dust suction hood, and the dust suction hood drives the lifting of the L-shaped toothed plate, causing the rotating shaft, the main gear, and the two driven gears to rotate synchronously. The driven gear cooperates with the pushing tooth to realize the forward and backward movement of the side pressing plate. The relative sliding of the wedge block and the driving groove, and the simultaneous use of spring three facilitate the mutual approach or separation of the two moving plates. When the dust suction hood descends to an appropriate position, two inner pressing plates press against the front and rear ends of the insulating support block, the pressing plate presses against the side of the insulating support block, and two upper pressing plates press against the top edge of the insulating support block, achieving comprehensive locking and fixing of the insulating support block, improving the tightness of the connection of multiple insulating support blocks, facilitating subsequent machining. The dust suction hood timely sucks away the generated debris, reducing pollution to the L-shaped support plate, eliminating the need for manual cleaning. At the same time, the dust suction hood can reduce noise generation and reduce the splashing of debris, ensuring safe and reliable use. Description of the Drawings

Specific embodiments

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1 to 6 , the present invention provides a positioning device for processing transformer insulation spacers, including a processing table 1, an L-shaped support plate 2 and a bracket 3 connected to the top of the processing table 1. The L-shaped support plate 2 is connected with a pressing mechanism 1 and a pressing mechanism 2 for pressing the insulation spacers. The pressing mechanism 1 includes two moving plates 18, two inner pressing plates 9, a spring 30, two wedge blocks 26, and a plurality of springs 22. The moving plates 18 are movably connected to the L-shaped support plate 2. The spring 30 is used to drive the two moving plates 18 to move away from each other. The two ends of the spring 22 are connected to the inner pressing plate 9 and the moving plate 18. The wedge blocks 26 are connected to the ends of the moving plates 18. The pressing mechanism 2 includes a side pressing plate 10, a pressing plate 25, a plurality of springs 23, and two driving grooves 27. The side pressing plate 10 is movably connected to the processing table 1. The two ends of the spring 23 are connected to the side pressing plate 10 and the pressing plate 25. The driving grooves 27 are provided on the side pressing plate 10 and are matched with the wedge blocks 26. The inner wall of the driving groove 27 is a smooth surface to reduce the contact friction with the wedge blocks 26. The bracket 3 is connected with a driving mechanism for driving the side pressing plate 10 to reciprocate.

[0019] Before processing, the dust suction hood 7 is at an appropriate height position. At this time, there is sufficient space below the dust suction hood 7, which is convenient for the feeding operation.

[0020] Place multiple support blocks on the L-shaped support plate 2. The air cylinder 6 drives the dust suction hood 7 to move downward, synchronously driving the L-shaped toothed plate 8 to move downward. The L-shaped toothed plate 8 drives the main gear 12 to rotate, synchronously driving the rotating shaft 13 and two driven gears 14 to rotate. The driven gear 14 drives the pushing tooth 11 to move, causing the side pressing plate 10 to move forward, and the wedge block 26 and the driving groove 27 to slide relative to each other. Make the two moving plates 18 approach each other, driving the two upper pressing plates 17 to approach each other. When the dust suction hood 7 descends to an appropriate position, multiple support blocks can be covered, and the inner pressing plate 9 presses against the front and rear ends of the support blocks. The first spring 22 is compressed, the pressing plate 25 presses against the side of the support block, and the two upper pressing plates 17 press against the top edge of the support bar. At this time, the third spring 30 is in a compressed state, realizing comprehensive locking and fixing of the insulating support blocks, improving the tightness of the connection of multiple insulating support blocks, and facilitating subsequent machining. At the same time, the dust suction hood 7 timely sucks away the generated debris, reducing the pollution to the L-shaped support plate 2, eliminating the need for manual cleaning. At the same time, the dust suction hood 7 can reduce the generation of noise and reduce the splashing of debris, making it safe and reliable to use.

[0021] The first pressing mechanism further includes a guiding groove 29, multiple guiding columns 19, an upper pressing plate 17, and an inclined surface 28. The guiding groove 29 is used to guide the moving plate 18. The end of the guiding column 19 is connected to the inner pressing plate 9, and the guiding column 19 is slidably connected to the moving plate 18. The upper pressing plate 17 is connected to the top of the moving plate 18, and the inclined surface 28 is arranged on the upper pressing plate 17. When the two moving plates 18 approach each other, the end of the moving plate 18 slides in the guiding groove 29, improving the stability of the movement of the moving plate 18. The inner pressing plate 9 presses against the front and rear ends of the support block, the guiding column 19 and the moving plate 18 slide relative to each other, and the first spring 22 is gradually compressed, so that the pressure exerted by the inner pressing plate 9 on the support block also gradually increases. The inclined surface 28 presses against the top edge of the support block, facilitating the limiting and fixing of the support block.

[0022] The guiding groove 29 is arranged on the L-shaped support plate 2. The moving plate 18 is slidably connected to the guiding groove 29. The third spring 30 is located in the guiding groove 29, and both ends of the third spring 30 are connected to the moving plate 18. When the side pressing plate 10 moves backward, the driving groove 27 and the wedge block 26 slide relative to each other, and the compressed third spring 30 can drive the two moving plates 18 to move away from each other, facilitating the loosening of the support block.

[0023] The second pressing mechanism further includes multiple sliding columns 24. The end of the sliding column 24 is connected to the pressing plate 25, and the sliding column 24 is slidably connected to the side pressing plate 10. During the forward movement of the side pressing plate 10, the pressing plate 25 presses against the side of the support block, the sliding column 24 and the side pressing plate 10 slide relative to each other, and the second spring 23 is gradually compressed, so that the pressure exerted by the pressing plate 25 on the support block gradually increases. Together with the use of the inner pressing plate 9 and the upper pressing plate 17, comprehensive locking and fixing of the support block are realized.

[0024] The second spring 23 is sleeved on the sliding column 24, and both ends of the second spring 23 are connected to the pressing plate 25 and the side pressing plate 10.

[0025] The driving mechanism includes a cylinder 6, a dust suction hood 7, an L-shaped tooth plate 8, two pushing teeth 11, a main gear 12, a rotating shaft 13, two driven gears 14, two support seats 15, and two sliding grooves 16. The cylinder 6 is connected to the bracket 3, and the power output end of the cylinder 6 is connected to the dust suction hood 7. The end of the L-shaped tooth plate 8 is connected to the dust suction hood 7, and the L-shaped tooth plate 8 is matched with the main gear 12. The main gear 12 is connected to the center of the rotating shaft 13. The driven gears 14 are fixedly connected to the rotating shaft 13. The rotating shaft 13 is rotatably connected to the support seats 15 to improve the stability of the rotation of the rotating shaft 13, that is, the main gear 12 and the two driven gears 14 rotate stably. The support seats 15 are connected to the top of the L-shaped support plate 2. The end of the pushing tooth 11 is connected to the side pressing plate 10. The driven gear 14 is matched with the pushing tooth 11. The sliding groove 16 is used for guiding the pushing tooth 11.

[0026] The upper part of the L-shaped tooth plate 8 is provided with teeth. During the downward movement of the dust suction hood 7, the L-shaped tooth plate 8 also moves downward, but does not drive the main gear 12 to rotate. Until the dust suction hood 7 moves downward to a specified position, the teeth are connected to the main gear 12. When the dust suction hood 7 continues to move downward, it can drive the main gear 12 to rotate. The main gear 12 drives the rotating shaft 13 to rotate, realizing the rotation of the two driven gears 14. The driven gears 14 cooperate with the pushing teeth 11 to realize the synchronous forward movement of the two pushing teeth 11. The pushing teeth 11 push the side pressing plate 10 forward. Until the dust suction hood 7 covers the support blocks, multiple support blocks are in a positioned state.

[0027] The pushing tooth 11 is meshed and connected with the driven gear 14, and the pushing tooth 11 is slidably connected to the sliding groove 16. The sliding groove 16 is arranged at the top of the L-shaped support plate 2. The sliding groove 16 serves a good guiding purpose for the pushing tooth 11, improving the stability of the reciprocating movement of the pushing tooth 11, that is, the side pressing plate 10 moves stably. And the driven gear 14 and the pushing tooth 11 achieve a good connection purpose, improving the transmission effect.

[0028] An opening 20 is arranged on the side of the dust suction hood 7, and a corrugated pipe 5 is connected to the center of the top of the dust suction hood 7. The corrugated pipe 5 is connected to a dust suction pipe 4, and the dust suction pipe 4 is connected to a dust suction fan. The robotic arm enters the dust suction hood 7 through the opening 20, facilitating the processing operation of multiple support blocks. A sound insulation cotton is arranged in the sandwich layer of the dust suction hood 7, which has a good sound insulation effect. Further, during the processing, by generating suction on the dust suction pipe 4 and the corrugated pipe 5 through the dust suction fan, the debris can be timely sucked away, reducing the pollution to the L-shaped support plate 2 and also avoiding the splashing of the debris.

[0029] Two connecting columns 21 are connected to the side of the dust suction hood 7. The connecting columns 21 are slidably connected to the L-shaped support plate 2, and the L-shaped tooth plate 8 penetrates through the L-shaped support plate 2 and the processing table 1, playing a good guiding role for the dust suction hood 7 and improving the stability of the lifting of the dust suction hood 7.

[0030] After the processing is completed, the air cylinder 6 drives the dust suction hood 7 to move upward, synchronously driving the L-shaped tooth plate 8 to move upward. The L-shaped tooth plate 8 drives the main gear 12 to rotate, driving the rotating shaft 13 and the two driven gears 14 to rotate. The driven gears 14 drive the pushing tooth 11 to move backward, moving the side pressing plate 10 backward, separating the pressing plate 25 from the supporting block. At the same time, the wedge block 26 slides relative to the driving groove 27, and the compressed spring three 30 drives the two moving plates 18 to move away from each other, separating the inner pressing plate 9 from the supporting block, and the upper pressing plate 17 is synchronously separated from the supporting block, realizing a comprehensive loosening treatment of the supporting block. At this time, the dust suction hood 7 rises to an appropriate height position, and the distance between the two upper pressing plates 17 increases, facilitating the unloading operation of the supporting block.

[0031] A positioning method for a positioning device used in the processing of transformer insulation supporting blocks includes the following steps: Step 1: Place multiple insulation supporting blocks on the L-shaped support plate 2. The air cylinder 6 drives the dust suction hood 7 to move downward, synchronously driving the L-shaped tooth plate 8 to move downward. The L-shaped tooth plate 8 drives the main gear 12 to rotate, synchronously driving the rotating shaft 13 and the two driven gears 14 to rotate. The driven gears 14 drive the pushing tooth 11 to move forward, further driving the side pressing plate 10 to move forward, causing the wedge block 26 to slide relative to the driving groove 27, driving the two moving plates 18 to move closer to each other, and driving the two inner pressing plates 9 to move closer to each other. At this time, the spring three 30 is in a compressed state; Step 2: When the dust suction hood 7 descends to an appropriate position, the two inner pressing plates 9 press tightly on the front and rear ends of the insulation supporting block, the pressing plate 25 presses tightly on the side of the insulation supporting block, and the two upper pressing plates 17 press tightly on the top edge of the insulation supporting block, realizing a comprehensive locking and fixing of the insulation supporting block, improving the tightness of the connection of multiple insulation supporting blocks, facilitating subsequent machining. The dust suction hood 7 timely sucks away the generated debris, reducing the pollution to the L-shaped support plate 2, eliminating the need for manual cleaning. At the same time, the dust suction hood 7 can reduce the generation of noise and the splashing of debris, and is safe and reliable to use; Step 3: After the machining is completed, the air cylinder 6 drives the dust suction hood 7 to move upward, moving the dust suction hood 7 away from the L-shaped support plate 2, leaving enough space for taking out the insulation supporting block. The dust suction hood 7 drives the L-shaped tooth plate 8 to move upward, causing the main gear 12 to rotate, synchronously driving the two driven gears 14 to rotate, and the two pushing teeth 11 move backward synchronously, driving the side pressing plate 10 to move backward, separating the pressing plate 25 from the insulation supporting block. At the same time, the wedge block 26 slides relative to the driving groove 27, and the compressed spring three 30 drives the two moving plates 18 to move away from each other, separating the inner pressing plate 9 and the upper pressing plate 17 from the multiple insulation supporting blocks, realizing the loosening treatment of the insulation supporting block. At this time, the distance between the two upper pressing plates 17 increases, facilitating the unloading operation.

At this time, the distance between the two upper pressure plates (17) is increased, which is convenient for unloading operations.
