Description

Technical Field

[0001] This invention relates to the field of transformer processing technology, specifically to a transformer core processing equipment. Background Technology

[0002] A transformer is a device used to transform AC voltage, current and impedance. The iron core is the core component of the transformer and is the main magnetic circuit part of the transformer. It is made of stacked silicon steel sheets.

[0003] During the processing of transformer cores, in order to enhance their moisture resistance, corrosion resistance, and insulation performance, their surface needs to be coated with paint. However, manual spraying is difficult in many ways. To address this, Chinese Patent No. CN217788187U discloses a processing device for transformer cores. To solve the problems of cumbersome operation and poor results of existing manual core spraying, this patent includes a cylinder fixedly connected to the side wall of the chassis, a fixed box fixedly connected to the output end of the cylinder, and an extrusion table connected to the output end of the fixed box; a spraying assembly including a motor fixedly connected to the top of the chassis, a reciprocating motion component fixedly connected to the output end of the motor, and a glue sprayer fixedly connected to the output end of the reciprocating motion component; and an adjustment assembly connected to the inner wall of the fixed box, which cooperates with the spraying assembly.

[0004] The inventors discovered that, when applying the aforementioned patented technology to larger shell-type iron cores, it is difficult to carry out the spraying operation. Large shell-type iron cores are large in volume and heavy in weight. For such iron cores, the general spraying method is to assemble and fix them and then use a handheld spray gun for spraying. Due to their large size, it is inconvenient to turn them over. Workers can only hold the spray gun and spray around the shell-type iron core. The amount of spraying is large and the spraying is uneven, which will reduce the spraying efficiency of the iron core to a certain extent. Summary of the Invention

[0010] As a further embodiment of the present invention, magnetic blocks are fixedly connected to the upper and lower ends of the mounting bracket near the adjustment plate. The adjustment plate is a metal plate, and the magnetic blocks are attracted to the metal plate.

[0011] As a further embodiment of the present invention, the outer surface of the right connector is provided with a positioning component, the positioning component including two limiting blocks, one side of the two limiting blocks being fixedly connected to the right connector, the relative positions of the two limiting blocks being rotatably connected to a rotating shaft, the arc surface of the rotating shaft being fixedly connected to a locking block, the surface of the adjusting plate being fixedly connected to a rectangular block, the rectangular block abutting against the locking block, the arc surface of the rotating shaft being fitted with a torsion spring, the two ends of the torsion spring being fixedly connected to the limiting block and the locking block respectively.

[0012] As a further embodiment of the present invention, a fixing structure is provided at the connection between the left half ring and the right half ring. The fixing structure includes a right clamping plate and a left clamping plate. The right clamping plate is fixedly connected to the right half ring, and the left clamping plate is fixedly connected to the left half ring. The left clamping plate and the right clamping plate abut against each other. A through hole is opened on the surface of the left clamping plate. A top block is fixedly connected to the surface of the right clamping plate. The top block passes through the through hole. A locking hole is opened on the surface of the top block.

[0015] As a further embodiment of the present invention, a screw is rotatably connected inside the square hole, the arc surface of the screw is threadedly connected to the positioning block, an auxiliary tooth is fixedly connected to the upper end of the screw, an adjusting tooth is rotatably connected to the rear surface of the fixing plate, the adjusting tooth meshes with the auxiliary tooth, and a handle is fixedly connected to the surface of the adjusting tooth.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. The left and right swing arm assemblies, respectively set at both ends of the horizontal plate, can be opened and closed by rotating the rotating block. When the left and right swing arm assemblies rotate and open, the left and right half rings, which are symmetrical and the same size, are released from their abutment state and are in an open arm position. After the entire device is pushed into one of the core columns of the shell-type iron core, the left and right swing arm assemblies return to the center, causing the left and right half rings to overlap and abut. Then, the motor on the toothed block drives the entire spraying device to rotate along the closed inner ring formed by the left and right half rings, thereby performing all-round rotational spraying on the iron core.

[0017] 2. Through the setting of the falling component, when the motor drives the gear to rotate and moves in conjunction with the meshing toothed block, it drives the L-shaped plate to rotate counterclockwise around the left and right halves of the ring. With each rotation, the long rod at the lower end of the L-shaped plate pushes the protrusion below, causing it to drive the rotating ring to rotate clockwise. During this process, the movable rod moves to the left in sync. When it moves to the leftmost end in the falling slot, it slides down the inclined groove of the falling slot due to gravity. During this sliding process, the rotating ring rotates counterclockwise again until the movable rod reaches the lower right end of the falling slot. At this time, the protrusion returns to its original position, and the entire left and right halves of the ring move down a certain distance. This cycle repeats. After each spraying revolution, it will automatically fall a section to start the next spraying section. The whole process is automatic and does not require an additional motor drive, thus reducing power consumption.

[0018] 3. By setting up a fixed structure, after the left half ring and the right half ring are spliced ​​together, the left clamp plate and the right clamp plate abut against each other. At the same time, the top block on the right clamp plate is inserted into the through hole on the left clamp plate. Then, slide the insert plate down so that the insert plate is inserted into the snap hole on the surface of the top block, and the fixation is completed, achieving the purpose of quick fixation.

[0019] 4. By using the sliding rod, after rotating the rotating block and adjusting the angle of the left and right swing arm assemblies, the rod can be pushed down to insert the fixing rod at the lower end of the circular plate into several circular holes, thereby fixing the rotating block. In addition, the handle can be rotated to rotate the adjusting gear, which in turn drives the auxiliary gear and screw to rotate, thereby moving the positioning block on the arc surface of the screw up and down, thus adjusting the vertical position of the entire left and right swing arm assemblies to adapt to different shell-type iron core spraying.

[0023] Example 1, please refer to Figure 1-11The present invention provides a technical solution: 1. A transformer core processing device, comprising three fixing plates 1, the three fixing plates 1 being installed side by side, a base 2 being installed on the lower surface of the fixing plate 1, a square hole being opened on the surface of the fixing plate 1, and a spraying structure 3 for uniformly spraying a shell-type iron core being provided on the surface of the fixing plate 1, the spraying structure 3 including a positioning block 31, the positioning block 31 being slidably connected to the fixing plate 1, the two sides of the positioning block 31 being slidably connected to the square hole, and a horizontal plate 32 being fixedly connected to the two sides of the positioning block 31, the two ends of the horizontal plate 32 being rotatably connected to a rotating... The moving block 33 has a right swing arm assembly 34 located on its surface near the right end of the horizontal plate 32, and a left swing arm assembly 36 located on its surface near the left end of the horizontal plate 32. The right swing arm assembly 34 includes a right support arm 341, which is fixedly connected to the moving block 33 near the right end of the horizontal plate 32. One end of the right support arm 341 is fixedly connected to a right connector 342, and the inner wall of the right connector 342 is fixedly connected to a mounting bracket 343. A drop assembly 35 for automatically lowering the height during spraying is provided on one side of the mounting bracket 343.

[0024] The left swing arm assembly 36 and the right swing arm assembly 34, respectively, are set at both ends of the horizontal plate 32. The rotating block 33 can rotate to open and close them. After they open, they wrap around one core column of the shell-type iron core, which facilitates the subsequent spraying operation. At the same time, after one round of spraying, they can automatically adjust and fall a certain distance.

[0025] like Figure 4-7As shown, a fixed shaft 344 is fixedly connected to the inner surface of the mounting bracket 343. A sliding disk 345 is slidably connected to the arc surface of the fixed shaft 344. A right connecting plate 346 is fixedly connected to the lower surface of the sliding disk 345. A right half-ring 347 is fixedly connected to one end of the right connecting plate 346. An L-shaped plate 348 is slidably connected to the upper surface of the right half-ring 347. A liquid storage tank 349 is fixedly connected to the upper surface of the L-shaped plate 348. A nozzle 3410 is fixedly connected to one side of the lower end of the L-shaped plate 348. The nozzle 3410 and the liquid storage tank 349 are connected through a pipe. A motor 3411 is fixedly connected to the side of the lower end of the L-shaped plate 348 away from the nozzle 3410. The output end of the motor 3411 is placed downwards. A gear 3412 is fixedly connected to the output end of the motor 3411. The arm assembly 36 includes a left support arm 361, which is fixedly connected to a rotating block 33 near the left end of the horizontal plate 32. A left connector 362 is fixedly connected to one end of the left support arm 361. A movable frame 363 is fixedly connected to the inner wall of the left connector 362. A positioning plate 364 is fixedly connected to the inner surface of the movable frame 363. A block 365 is slidably connected to the surface of the positioning plate 364. A left connecting plate 366 is fixedly connected to the lower surface of the block 365. A left half-ring 367 is fixedly connected to one end of the left connecting plate 366. The size of the left half-ring 367 is similar to that of the right half-ring 347. The left half-ring 367 abuts against the right half-ring 347. The inner walls of both the left half-ring 367 and the right half-ring 347 are provided with evenly spaced toothed blocks that mesh with gears 3412.

[0026] When the left and right swing arm assemblies 36 and 347 rotate and open, the left and right half-rings 367 and 347, which are symmetrical and the same size, are released from their abutment state and are in an open arm position. After the entire device is pushed into one of the core columns of the shell-type iron core, the left and right swing arm assemblies 36 and 34 return to the center, causing the left and right half-rings 367 to overlap and abut. Then, the motor 3411 on the toothed block drives the entire spraying device to rotate along the closed inner ring formed by the left and right half-rings 367 and 347, thereby performing all-round rotational spraying on the iron core.

[0027] like Figure 4 and Figure 6As shown, the falling assembly 35 includes an adjusting plate 351, one end of which is rotatably connected to the mounting frame 343. The adjusting plate 351 is curved in an arc shape. A handle is fixedly connected to the surface of the adjusting plate 351. Falling slots 352 are evenly opened from top to bottom on the surface of the adjusting plate 351. The falling slots 352 are shaped like an inverted "Z" with their ends connected. A rotating ring 353 is slidably connected to the arc surface of the sliding disc 345. A protrusion 354 is fixedly connected to the arc surface of the rotating ring 353 near the L-shaped plate 348. A movable rod 355 is fixedly connected to the arc surface of the rotating ring 353 near the falling slot 352. One end of the movable rod 355 passes through the inner wall of the falling slot 352. A long rod 356 is fixedly connected to the lower surface of the L-shaped plate 348 near the protrusion 354. The long rod 356 abuts against the protrusion 354.

[0028] With the arrangement of the falling assembly 35, when the motor 3411 drives the gear 3412 to rotate and moves in conjunction with its meshing gear block, it drives the L-shaped plate 348 to rotate counterclockwise around the left half ring 367 and the right half ring 347. Each rotation causes the long rod 356 at the lower end of the L-shaped plate 348 to push the lower protrusion 354, causing it to drive the rotating ring 353 to rotate clockwise. During this process, the movable rod 355 moves synchronously to the left. When it moves to the leftmost end within the falling slot 352, it will... Due to gravity, the ring slides downward along the inclined groove of the drop slot 352. During this sliding process, the rotating ring 353 will rotate counterclockwise until the movable rod 355 reaches the lower right end of the drop slot 352. At this time, the protrusion 354 returns to its original position, and the entire left half ring 367 and right half ring 347 will move downward a certain distance. This cycle repeats, and after each round of spraying, the ring will automatically drop a section to start the next section of spraying. The whole process is automatic and does not require an additional motor 3411 to drive it, thus reducing power consumption.

[0029] In addition, two locking blocks 39 are fixedly connected to the lower surface of the L-shaped plate 348 at the position corresponding to the right half-ring 347. The distance between the two locking blocks 39 is greater than the thickness of the right half-ring 347. The two locking blocks 39 are used to lock the L-shaped plate 348 in place, thereby ensuring the stability of its circumferential rotation. Magnetic blocks 38 are fixedly connected to the upper and lower ends of the mounting bracket 343 near the adjusting plate 351. The adjusting plate 351 is a metal plate, and the magnetic blocks 38 are attracted to the metal plate. The magnetic blocks 38 facilitate the attraction and fixation of the adjusting plate 351 after rotation, thereby fixing and limiting the position of the adjusting plate 351.

[0030] like Figure 8As shown, the outer surface of the right connector 342 is provided with a positioning component 37. The positioning component 37 includes two limiting blocks 371. One side of the two limiting blocks 371 is fixedly connected to the right connector 342. The relative positions of the two limiting blocks 371 are rotatably connected to a rotating shaft 372. A locking block 373 is fixedly connected to the arc surface of the rotating shaft 372. A rectangular block 374 is fixedly connected to the surface of the adjusting plate 351. The rectangular block 374 abuts against the locking block 373. A torsion spring 375 is sleeved on the arc surface of the rotating shaft 372. The two ends of the torsion spring 375 are fixedly connected to the limiting block 371 and the locking block 373 respectively.

[0031] With the setting of the locking block 373, after the adjusting plate 351 is rotated to the working position, the locking block 373 can be locked into the rectangular block 374, thereby fixing the adjusting plate 351. At the same time, the torsion spring 375 gives the locking block 373 a force that is always inward.

[0032] like Figure 9 As shown, a fixing structure 4 is provided at the connection between the left half ring 367 and the right half ring 347. The fixing structure 4 includes a right clamping plate 41 and a left clamping plate 42. The right clamping plate 41 is fixedly connected to the right half ring 347, and the left clamping plate 42 is fixedly connected to the left half ring 367. The left clamping plate 42 abuts against the right clamping plate 41. A through hole is opened on the surface of the left clamping plate 42. A top block 43 is fixedly connected to the surface of the right clamping plate 41. The top block 43 passes through the through hole. A locking hole is opened on the surface of the top block 43. Two L-shaped blocks 44 are fixedly connected to the surface of the left clamping plate 42 near the upper end of the through hole. An insert plate 45 is slidably connected to the inner wall of the two L-shaped blocks 44. The insert plate 45 passes through the locking hole.

[0033] With the setting of the fixing structure 4, after the left half ring 367 and the right half ring 347 are spliced ​​together, the left clamping plate 42 and the right clamping plate 41 abut against each other. At the same time, the top block 43 on the right clamping plate 41 is inserted into the through hole on the left clamping plate 42. At this time, the inserting plate 45 is slid down so that the inserting plate 45 is inserted into the snap hole on the surface of the top block 43, thus completing the fixing and connecting the left half ring 367 and the right half ring 347 into one piece.

[0034] Example 2, based on Example 1, such as Figure 10 and 11As shown, the upper and lower surfaces of the rotating block 33 are provided with an adjustment structure 5. The adjustment structure 5 includes a rod 501, which is slidably connected to the rotating block 33 and the horizontal plate 32 respectively. A circular plate 502 is fixedly connected to the arc surface of the rod 501. Several fixed rods 503 are fixedly connected to the lower surface of the circular plate 502. Several circular holes 504 are evenly opened on the upper surface of the rotating block 33 corresponding to the positions of the fixed rods 503. An upper baffle 505 is fixedly connected to the arc surface of the circular plate 502. A lower baffle 506 is fixedly connected to the lower end of the rod 501. A movable rod 507 is fixedly connected to the relative position of the upper baffle 505 and the lower baffle 506. The arc surface of the movable rod 507 is slidably connected to the horizontal plate 32.

[0035] By using the sliding rod 501, after rotating the rotating block 33 and adjusting the angle between the left swing arm assembly 36 and the right swing arm assembly 34, the rod 501 can be pushed downwards, causing the fixing rod 503 at the lower end of the circular plate 502 to be inserted into several circular holes 504, thereby fixing the rotating block 33.

[0036] In addition, a spring 508 is fitted on the arc surface of the movable rod 507, and the two ends of the spring 508 are fixedly connected to the lower baffle 506 and the horizontal plate 32, respectively.

[0037] By using the spring 508, when the insertion rod 501 is pulled upward, the spring 508 is compressed. When it is necessary to fix it, the insertion rod 501 is released, and the spring 508 rebounds, causing the insertion rod 501 to quickly return to its original position downward. At the same time, the spring 508 gives the insertion rod 501 a downward force, making it more securely fixed.

[0038] Meanwhile, a screw 509 is rotatably connected inside the square hole. The arc surface of the screw 509 is threadedly connected to the positioning block 31. An auxiliary tooth 510 is fixedly connected to the upper end of the screw 509. An adjusting tooth 511 is rotatably connected to the rear surface of the fixing plate 1. The adjusting tooth 511 meshes with the auxiliary tooth 510. A handle 512 is fixedly connected to the surface of the adjusting tooth 511.

[0039] By rotating the handle 512, the adjusting gear 511 can be rotated, which in turn drives the auxiliary gear 510 and the screw 509 to rotate. This causes the positioning block 31 on the arc surface of the screw 509 to move up and down, thereby adjusting the up and down positions of the entire left swing arm assembly 36 and right swing arm assembly 34. This makes it easier to align the core column of the shell-type iron core and facilitates subsequent spraying.

[0040] Working Principle: When spraying the shell-type iron core, the rotating block first opens and closes, causing the left and right halves of the ring, which are symmetrical and the same size, to disengage from their abutment state as the left and right swing arm assemblies rotate and open. This allows the entire device to be pushed into one of the core columns of the shell-type iron core. Then, the left and right swing arm assemblies return to their original position, causing the left and right halves of the ring to overlap and abut. Subsequently, the motor drives the gears to rotate, and as the gears mesh with them move, the L-shaped plate rotates counterclockwise around the left and right halves of the ring. The needle rotates in a circular motion. With each rotation, the long rod at the lower end of the L-shaped plate pushes the protrusion below, causing the rotating ring to rotate clockwise. During this process, the movable rod moves to the left simultaneously. When it reaches the leftmost end of the drop slot, it slides down the inclined groove of the drop slot due to gravity. During this sliding process, the rotating ring rotates counterclockwise until the movable rod reaches the lower right end of the drop slot. This process is one cycle. One rotation of the motor-driven spraying is one cycle. This cycle continues until the core column of the shell-type iron core is sprayed.
