[0025] A stacking method of a transformer core stacking device for assembling a transformer, comprising the following steps:

[0026] S1: Place the iron cores into the barrel. According to the number of iron cores to be stacked, loosen the bolts and move the top block along the slide bar. Determine the number of iron cores according to the scale on the slide bar. Move the top block to the appropriate scale and fix it with bolts.

[0027] S2: Then the cylinder is started to work, so that the cylinder contracts and the drive tube moves downward. When the drive tube abuts against the cylindrical block and continues to move downward, the drive tube slides in the limit tube. Since the protrusion in the drive tube slides in the thread groove, the protrusion pushes the rotating rod to rotate counterclockwise during the sliding of the drive tube in the limit tube, thereby causing the second gear to rotate counterclockwise. Through the meshing action of the second gear and the fan gear, the fan gear rotates clockwise. At the same time, through the abutment action of the cam opened on one side of the fan gear and the vibration rod, the vibration rod vibrates laterally under the cooperation of the first spring. The first gear is moved to the left by the cam, and the second gear is moved to the right by the cam. The second gear is moved to the right by the cam, and the second gear is moved to the right by the cam. The cam is moved to the right by the cam. The cam is moved to the right by the cam. The cam is moved to the right by the cam.

[0028] S3: In the process of the block moving out from the block entrance, the first rack is fixedly connected to the movable plate, so that the movable plate drives the first rack fixedly connected to the movable plate to move during the movement, and the meshing action of the first rack and the gear ring drives the gear ring to rotate counterclockwise, and the limiting action of the arc groove and the slide rail makes the gear ring drive the slide rod close to the barrel during rotation, so that the top block enters into the barrel from the top block entrance, supports the iron cores that do not need to be stacked, and prevents them from falling.

[0029] S4: When the driving tube slides in the limiting tube, the cross-section of the lower end of the driving tube becomes trapezoidal, and one end of the locking rod is provided with an inclined surface, so that the locking rod is squeezed to the right, and the second spring is compressed at the same time. When the driving tube slides to the maximum stroke in the limiting tube, the elastic force of the second spring resets the locking rod, thereby preventing the driving tube from resetting. After the cylinder is extended to the maximum stroke, the top of the mounting frame causes the push rod to rotate, thereby causing the locking rod to move to the right, and the locking rod is separated from the bottom of the driving tube. At this time, each part is reset under the action of the reset spring force, and the iron core in the barrel falls onto the block, and this reciprocating process is repeated to stack the iron cores.

[0030] Compared with the prior art, one or more of the above technical solutions have the following beneficial effects:

[0031] 1. The movable plate moves to drive the first rack to move, and the meshing action of the first rack and the gear ring makes the rack drive the gear ring to rotate on the barrel when it moves. The coordinated action of the arc groove and the slide rail makes the gear ring drive the slide bar to slide on the slide rail when it rotates, thereby driving the top block to move together, so that the top block can hold the iron core to prevent it from falling. In this way, the height of the top block can be adjusted according to the scale on the slide bar, thereby achieving the purpose of controlling the number of stacked iron cores, avoiding the situation where only one iron core can be stacked at a time, and making the stacking efficiency higher.

[0032] 2. The cam is rotated by rotating the sector gear. Through the abutment between the cam and the vibration rod and the action of the first spring, when the cam rotates, the vibration rod vibrates. Through the lateral vibration of the vibration rod, the other end of the vibration rod frequently contacts and disengages from the side of the barrel, thereby striking the barrel, making the iron core in the barrel fall more easily and preventing the iron core from getting stuck in the barrel.

[0033] 3. When the driving tube slides in the limiting tube, the cross-section of the lower end of the driving tube is trapezoidal, and one end of the locking rod is provided with an inclined surface, so that the locking rod is squeezed to the right, and the second spring is compressed at the same time. When the driving tube slides to the maximum stroke in the limiting tube, the elastic force of the second spring resets the locking rod, thereby preventing the driving tube from resetting. After the cylinder is extended to the maximum stroke, the top of the mounting frame causes the push rod to rotate, thereby causing the locking rod to move to the right, and the locking rod is separated from the bottom of the driving tube. At this time, each part is reset under the action of the reset spring force, and the iron core in the barrel falls onto the block, and this reciprocating process is repeated to stack the iron cores, so that each component in the device is linked, which is more energy-efficient and has a higher degree of automation.

When the extrusion assembly 41 moves downward and is extruded with the base 1, the extrusion assembly 41 works, causing the sector gear 43 to rotate, and then the first gear 44 to rotate. Through the rotation of the first gear 44, the iron core blocking assembly 3 works, and then the adjustable blocking assembly 6 works. After the work is completed, the locking assembly 45 locks the extrusion assembly 41.

[0057] By arranging the lower ends of the four movable plates 32 to slide in the four first sliding grooves 312 respectively, the direction of the movable plate 32 is more stable when it moves. The lower end of the movable plate 32 is fixedly connected to a return spring 33, and the other end of the return spring 33 is fixedly connected to the lower limit plate 31, so that the movable plate 32 can be reset by the action of the return spring 33 after the movement is completed. A stop block 321 is provided on one side of the movable plate 32, so that the stop block 321 moves with the movable plate 32 when it moves, thereby achieving the purpose of supporting the iron core or detaching from the iron core.

[0060] The cylinder 2 contracts, driving the lower limit plate 31 fixedly connected to the output end of the cylinder 2 to move downward, thereby causing the limit tube 411, the drive tube 412, the rotating rod 413 and the second gear 414 to move downward together. When the drive tube 412 moves to contact with the base 1, it continues to move. During the continued movement, the drive tube 412 slides in the limit tube 411, causing the rotating rod 413 to rotate, thereby driving the second gear 414 to rotate. Through the meshing action of the second gear 414 and the fan gear 43, the fan gear 43 rotates, and at the same time, the fan gear 43 drives the first gear 44 to rotate through the rotating shaft 42. Through the meshing action of the first gear 44 and the second rack 322, the second rack 322 moves, thereby driving the movable rod to slide in the first slide groove 312, and the reset spring 33 is stretched.

[0066] The movable plate 32 moves to drive the first rack 34 to move, and the meshing action between the first rack 34 and the gear ring 61 causes the rack to drive the gear ring 61 to rotate on the barrel 5 when it moves. The arc groove 62 cooperates with the slide rail 63 to drive the slide rod 64 to slide on the slide rail 63 when the gear ring 61 rotates, thereby driving the top block 65 to move together, so that the top block 65 can support the iron core and prevent it from falling.

Through the abutment between the cam 431 and the vibration rod 55 and the action of the first spring 56, when the cam 431 rotates, the vibration rod 55 vibrates. Through the lateral vibration of the vibration rod 55, the other end of the vibration rod 55 frequently contacts and disengages from the side of the barrel 5, thereby striking the barrel 5.

[0073] Reference Fig. 9 As shown, the cross section of the lower end of the driving tube 412 is trapezoidal;

[0076] The driving tube 412 moves upward due to the squeezing action of the cylindrical block 13, so that the outer surface of the lower end of the driving tube 412 abuts against the inclined surface 452, so that the locking rod 451 is squeezed to the right and the second spring 453 is compressed. When the travel of the driving tube 412 reaches the maximum, under the action of the second spring 453, the locking rod 451 is reset to support the driving tube 412, thereby preventing the driving tube 412 from falling.

[0077] A stacking method of a transformer core stacking device for assembling a transformer, comprising the following steps:

[0078] S1: Place the iron cores into the barrel 5. According to the number of iron cores to be stacked, loosen the bolts and move the top block 65 along the slide bar 64. Determine the number of iron cores according to the scale on the slide bar 64. Move the top block 65 to the appropriate scale and fix it with bolts.

[0079] S2: Then start the cylinder 2 to make it contract and drive tube 412 move down. When drive tube 412 abuts against cylindrical block 13 and continues to move down, drive tube 412 slides in limit tube 411. Since protrusion 4122 in drive tube 412 slides in thread groove 4131, during the sliding process of drive tube 412 in limit tube 411, protrusion 4122 pushes rotating rod 413 to rotate counterclockwise, thereby making second gear 414 rotate counterclockwise. Through the meshing action of second gear 414 and fan gear 43, fan gear 43 rotates clockwise. At the same time, through the abutment action of cam 431 provided on one side of fan gear 43 and vibration rod 55, under the cooperation action of first spring 56, vibration is made. The rod 55 vibrates laterally and strikes the barrel 5. At the same time, since the upper end of the rotating shaft 42 is fixedly connected to the fan gear 43, and the lower end of the rotating shaft 42 is fixedly connected to the first gear 44, when the fan gear 43 rotates, the first gear 44 is driven to rotate. Through the meshing of the first gear 44 and the second rack 322, the second rack 322 is fixedly connected to a movable plate 32. The four movable plates 32 are abutted. Therefore, when the first gear 44 rotates clockwise, the second rack 322 is driven to move backward, and then the movable plate 32 fixedly connected to the second rack 322 is driven to move backward, so that the stopper 321 on the movable plate 32 moves out from the stopper entrance 53, and the reset spring 33 is compressed. At this time, the iron core located above the stopper 321 falls onto the storage table 11, completing the stacking of the iron core.

[0080] S3: During the process of the block 321 moving out from the block entrance 53, the first rack 34 is fixedly connected to the movable plate 32, so that the movable plate 32 drives the first rack 34 fixedly connected to the movable plate 32 to move during the movement, and the first rack 34 engages with the gear ring 61, thereby driving the gear ring 61 to rotate counterclockwise, and the limiting effect of the arc groove 62 and the slide rail 63 makes the gear ring 61 drive the slide rod 64 to approach the barrel 5 during rotation, so that the top block 65 enters into the barrel 5 from the top block entrance 52, supports the iron cores that do not need to be stacked, and prevents them from falling.

[0081] S4: When the driving tube 412 slides in the limiting tube 411, the cross-section of the lower end of the driving tube 412 is trapezoidal, and one end of the locking rod 451 is provided with a slope 452, so that the locking rod 451 is squeezed to the right, and the second spring 453 is compressed at the same time.

8. The stacking method of a transformer core stacking device according to claim 7, characterized in that: The following steps are involved: S1: placing the iron cores into the barrel (5), loosening the bolts according to the number of iron cores to be stacked, moving the top block (65) along the slide bar (64), judging the number of iron cores according to the scale on the slide bar (64), moving the top block (65) to the appropriate scale, and fixing it with bolts; S2: Then the cylinder (2) is started to work, so that the cylinder (2) contracts and the drive tube (412) moves downward. When the drive tube (412) contacts the cylindrical block (13) and continues to move downward, the drive tube (412) slides in the limit tube (411). Since the protrusion (4122) in the drive tube (412) slides in the thread groove (4131), the protrusion (4122) pushes the rotating rod (413) to rotate counterclockwise during the sliding of the drive tube (412) in the limit tube (411), thereby causing the second gear (414) to rotate counterclockwise. Through the meshing action of the second gear (414) and the fan gear (43), the fan gear (43) rotates clockwise. At the same time, through the contact action of the cam (431) provided on one side of the fan gear (43) and the vibration rod (55), the vibration rod (55) is caused to rotate counterclockwise under the cooperation action of the first spring (56). (55) vibrates laterally and knocks the barrel (5). At the same time, since the upper end of the rotating shaft (42) is fixedly connected to the fan-shaped gear (43) and the lower end of the rotating shaft (42) is fixedly connected to the first gear (44), when the fan-shaped gear (43) rotates, the first gear (44) is driven to rotate.

Therefore, when the first gear (44) rotates clockwise, the second rack (322) is driven to move backward, thereby driving the movable plate (32) fixedly connected to the second rack (322) to move backward, so that the stopper (321) on the movable plate (32) moves out from the stopper entrance (53), and the reset spring (33) is compressed. At this time, the iron core located above the stopper (321) falls onto the storage table (11), completing the stacking of the iron core; S3: During the process of the stopper (321) moving out from the stopper entrance (53), the first rack (34) is fixedly connected to the movable plate (32), so that the movable plate (32) drives the first rack (34) fixedly connected to the movable plate (32) to move together during the movement, and the first rack (34) and the gear ring (61) are meshed, thereby driving the gear ring (61) to rotate counterclockwise. Through the limiting effect of the arc groove (62) and the slide rail (63), the gear ring (61) drives the slide bar (64) to approach the barrel (5) during the rotation, thereby causing the top block (65) to enter the barrel (5) from the top block entrance (52), and support the iron cores that do not need to be stacked, thereby preventing them from falling. S4: When the driving tube (412) slides in the limiting tube (411), the lower end of the driving tube (412) has a trapezoidal cross section, and one end of the locking rod (451) is provided with an inclined surface (452), so that the locking rod (451) is squeezed to the right, and the second spring (453) is compressed. When the driving tube (412) slides to the maximum stroke in the limiting tube (411), the elastic force of the second spring (453) resets the locking rod (451). , thereby preventing the drive tube (412) from resetting. After the cylinder (2) is extended to the maximum stroke, the push rod (454) is rotated through the action of the top of the mounting frame (12), thereby causing the locking rod (451) to move to the right, and the locking rod (451) is separated from the bottom of the drive tube (412). At this time, under the action of the reset spring (33), each part is reset, and the iron core in the barrel (5) falls onto the stopper (321), and this reciprocating process is repeated to stack the iron cores.
