[0035] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0036] An embodiment of the utility model provides a coil expanding device for expanding a coil. The coil expanding device facilitates the placement of the coil by moving a expanding component away from the coil placement position when placing the coil to be expanded, thereby solving the technical problem in the prior art that the expanding component easily blocks the coil and causes inconvenience in the placement of the coil.

[0037] The coil expansion device of this embodiment is as follows: Figure 1 As shown, it includes a frame 10, a placement table 20, a rotation drive unit 30, a mounting frame 40, a flaring drive unit 50 and a flaring unit 60. The placement table 20 is rotatably connected to the frame 10, and the placement table 20 is provided with a coil placement position 21; the rotation drive unit 30 is connected to the placement table 20, and is used to drive the placement table 20 to rotate; the mounting frames 40 are arranged at intervals along the circumference of the coil placement position 21 and are slidably connected to the frame 10 in a direction close to or away from the coil placement position 21; the flaring drive unit 50 is connected to each mounting frame 40, and is used to drive each mounting frame 40 to slide; the flaring unit 60 is slidably connected to each mounting frame 40, and can be connected to the coil by sliding in the direction of the coil placement position 21.

[0038] Specifically, the coil expanding device is provided with a frame 10, a placement table 20, a rotation drive unit 30, a mounting frame 40, an expansion drive unit 50 and an expansion unit 60. The placement table 20 is rotatably connected to the frame 10. The placement table 20 is provided with a coil placement position 21. When the coil is expanded, the coil to be expanded can be placed at the coil placement position 21. The rotation drive unit 30 is connected to the placement table 20. The rotation drive unit 30 can drive the coil at the coil placement position 21 to rotate by driving the placement table 20 to rotate. The mounting frame 40 is slidably connected to the frame 10 in a direction close to or away from the coil placement position 21. The expansion unit 60 is slidably connected to each mounting frame 40 along the height direction of the frame 10, and can be moved toward the coil placement position 21 by sliding toward the coil placement position 21. The coil is connected by sliding in the direction, and the expansion drive unit 50 is connected to each mounting frame 40. After the expansion unit 60 is connected to the coil, the expansion drive unit 50 drives each mounting frame 40 to slide in the direction away from the coil placement position 21, so that the expansion unit 60 pulls the coil to complete the expansion of one part of the coil. After completing the expansion of this part, the rotation drive unit 30 drives the coil to rotate at a small angle, and then expands another part of the coil. Finally, under the rotation of the coil and the expansion of each expansion unit 60, the expansion of the coil in the circumferential direction is completed. After completing the expansion of the coil, the expansion unit 60 can slide away from the coil placement position 21 in the direction away from the coil placement position 21, thereby facilitating the placement of the subsequent coil to be expanded.

[0039] It can be understood that the frame 10 can be any frame structure that provides support for the coil expansion device.

[0040] In this embodiment, Figure 1 As shown, there are three mounting frames 40, three expanding drive units 50 and three expanding units 60, each mounting frame 40 is spaced apart along the circumference of the coil placement position 21 and is slidably connected to the frame 10 in a direction approaching or moving away from the coil placement position 21, each expanding unit 60 is slidably connected to each mounting frame 40, and each expanding drive unit 50 is connected to each mounting frame 40, respectively, to drive each mounting frame 40 to move in a direction approaching or moving away from the coil placement position 21, and the three expanding units 60 operate simultaneously to expand the three positions of the coil simultaneously, thereby improving the expanding efficiency of the coil.

[0041] In this embodiment, each mounting frame 40 is slidably connected to the frame 10 via a sliding module formed by a slider and a slide rail.

[0042] It can be understood that the rotation driving unit 30 can be any driving device such as a rotary cylinder, a rotary motor, etc. that can drive the placement table 20 to rotate.

[0043] In one embodiment, Figure 1As shown, the rotation drive unit 30 includes a fixed frame 31 and a rotation drive member 32. The fixed frame 31 is slidably connected to the frame 10 along the height direction of the frame 10, and the rotation drive member 32 is fixed to the fixed frame 31. The placement table 20 is connected to the driving end of the rotation drive member 32, and is used to rotate by the drive of the rotation drive member 32. Specifically, the placement table 20 can be rotated under the drive of the rotation drive member 32. The fixed frame 31 is slidably connected to the frame 10. By sliding along the height direction of the frame 10, the placement table 20 can be driven to rise and fall. The lifting table can be lowered by descending and away from the flaring unit 60, so as to facilitate the placement of the coil. After the placement of the coil is completed, the fixed frame 31 can be driven to rise.

[0044] In this embodiment, the rotary driving member 32 is a rotary cylinder.

[0045] In this embodiment, Figure 1 As shown, the fixing frame 31 is slidably connected to the frame 10 through a sliding module formed by a combination of a slide rail and a slider.

[0046] In one embodiment, Figure 1 As shown, the coil expanding device further includes a lifting driving member 70, which is connected to the fixing frame 31 and is used to drive the fixing frame 31 to slide. Specifically, the placement table 20 can be lifted and lowered by the lifting driving member 70 driving the fixing frame 31.

[0047] In this embodiment, the lifting driving component 70 is a hydraulic cylinder.

[0048] It can be understood that the expansion drive unit 50 can be any driving device such as a cylinder, a hydraulic cylinder, a motor and a screw module that can drive the mounting frame 40 to slide.

[0049] It can be understood that the expansion unit 60 can be connected to the mounting bracket 40 by sliding in any direction, and it only needs to be able to slide closer to or away from the coil placement position 21.

[0050] In this embodiment, the expansion unit 60 is slidably connected to the mounting frame 40 along the height direction of the frame 10 .

[0051] It can be understood that the expansion unit 60 can be connected to the coil by any connection form such as snap-fitting, grabbing, etc., and it is only necessary to be able to slide and pull the coil in a direction away from the coil placement position 21 through the mounting frame 40.

[0052] In one embodiment, Figure 1-3As shown, the expansion unit 60 includes a lifting drive module 61 and an expansion piece 62. The lifting drive module 61 is slidably connected to the mounting frame 40 along the height direction of the frame 10. The expansion piece 62 is connected to the lifting drive module 61. The expansion piece 62 is used to sleeve the coil through the driving of the lifting drive module 61. Specifically, the lifting drive module 61 can realize the sliding connection with the mounting frame 40, and the expansion piece 62 can be driven to sleeve the coil, so that the expansion unit 60 expands the coil under the drive of the expansion drive unit 50. At the same time, when the coil completes the expansion in one direction, the lifting drive module 61 can also drive the expansion piece 62 to rise and disconnect from the coil, so as to facilitate the rotation drive unit 30 to control the rotation of the coil. After the coil rotates to another orientation, the lifting drive module 61 drives the expansion piece 62 to sleeve the coil again, and expands the coil in this orientation.

[0053] It can be understood that the lifting drive module 61 can be any driving device such as a cylinder, a hydraulic cylinder, etc. that can drive the expansion member 62 to slide.

[0054] In one embodiment, Figure 1-3 As shown, the lifting drive module 61 includes a sliding seat 611 and a driving cylinder 612. The sliding seat 611 is slidably connected to the mounting frame 40. The driving cylinder 612 is fixed to the sliding seat 611 and connected to the flaring member 62, and is used to drive the flaring member 62 to rise and fall. Specifically, the sliding seat 611 can realize the sliding connection between the lifting drive module 61 and the mounting frame 40, and the driving cylinder 612 can drive the flaring member 62 to be sleeved or away from the coil.

[0055] In this embodiment, Figure 1-3 As shown, the sliding seat 611 is slidably connected to the mounting frame 40 through a sliding module formed by a sliding rail and a sliding block.

[0056] In one embodiment, Figure 1-3 As shown, the expansion unit 60 also includes an anti-bias module 63, which is fixed to the lifting drive module 61. The anti-bias module 63 can be pressed against the side of the coil by sliding the mounting frame 40 toward the coil placement position 21. Specifically, when the rotation drive unit 30 drives the coil to rotate, the anti-bias module 63 presses against the side of the coil, thereby removing the edges and corners on the outside of the coil, ensuring the consistency of the coil expansion, and improving the success rate of the coil expansion.

[0057] In one embodiment, Figure 1-3As shown, the anti-deflection module 63 includes a top piece 631, one end of which is fixed to the lifting drive module 61, and the other end of the top piece 631 extends toward the coil placement position 21. The end of the top piece 631 close to the coil placement position 21 can be pressed against the side of the coil by sliding the mounting frame 40 toward the coil placement position 21. Specifically, during the rotation of the coil, the top piece 631 presses against the side of the coil, thereby ensuring the consistency of the expansion of the coil.

[0058] In this embodiment, since the position of the top piece 631 is fixed, it is suitable for tightening the coil during the rotation process of a standard model.

[0059] In one embodiment, Figure 1-3 As shown, the anti-bias module 63 includes a driver 632 and a top block 633. The driver 632 is fixed to the lifting drive module 61, and the top block 633 is fixed to the driving end of the driver 632, and is used to press against the side of the coil through the drive of the driver 632. Specifically, during the rotation of the coil, the driver 632 drives the top block 633 to press against the side of the coil, thereby ensuring the consistency of the expansion of the coil.

[0060] In this embodiment, the configuration of the driver 632 and the top block 633 can be applicable to the tightening of any type of coil during the rotation process.

[0061] In one embodiment, Figure 1-2 As shown, the coil expanding device further includes a lifting drive unit 80, which includes a first servo motor 81 and a first screw rod 82. The first screw rod 82 is rotatably connected to the mounting frame 40 and extends axially along the height direction of the frame 10. The first servo motor 81 is fixed to the mounting frame 40 and connected to the first screw rod 82, and is used to drive the first screw rod 82 to rotate. The lifting drive module 61 is threadedly connected to the first screw rod 82. Specifically, when the expanding unit 60 is lifted and lowered, the first servo motor 81 drives the first screw rod 82 to rotate, so that the lifting drive module 61 can be lifted and lowered.

[0062] In this embodiment, Figure 1-2 As shown, the lifting drive module 61 is threadedly connected to the first screw rod 82 via a sliding seat 611 .

[0063] In some embodiments, Figure 1-2As shown, the flaring drive unit 50 includes a second servo motor 51, a belt 52, and a second screw rod 53. One end of the second screw rod 53 is threadedly connected to the frame 10, and the other end of the second screw rod 53 extends in the direction of the coil placement position 21 and is rotatably connected to the mounting frame 40. The second servo motor 51 is fixed to the mounting frame 40, and the belt 52 is sleeved on the shaft of the second servo motor 51 and the second screw rod 53. Specifically, when the second servo motor 51 is started, the second screw rod 53 can be driven to rotate through the transmission of the belt 52, and the second screw rod 53 is threadedly connected to the frame 10, so that the second screw rod 53 moves axially, and then the mounting frame 40 can be driven to slide.

[0064] The specific working principle of the coil expanding device provided by the utility model is as follows: when the coil expanding work is performed, the coil to be expanded is placed in the coil placement position 21, the lifting drive member 70 drives the placement table 20 to rise by driving the fixed frame 31, the second servo motor 51 is started, and drives the second screw rod 53 to rotate, and the second screw rod 53 drives the mounting frame 40 to move toward the coil placement position 21 by rotating, and after moving to a certain position, the first servo motor 81 is started, and drives the first screw rod 82 to rotate, and the first screw rod 82 drives the sliding seat 611 to descend in the direction of the coil placement position 21, and descends to a certain position so that the anti-deflection module 63 presses the side of the coil tightly;

[0065] Then the driving cylinder 612 drives the expanding member 62 to descend and be connected with the coil at the coil placement position 21, and then the second servo motor 51 is started, so that the second screw rod 53 drives the mounting frame 40 to move in the direction away from the coil placement position 21, so that the expanding member 62 pulls the coil to expand the coil. After the expansion of this position is completed, the driving cylinder 612 drives the expanding member 62 to rise, so that the expanding member 62 is separated from the coil, and then the rotating driving member 32 drives the placement table 20 to rotate. During the rotation process, the anti-bias module 63 always presses against the side of the coil. After rotating a certain angle, the expanding member 62 is driven by the driving cylinder 612 to be connected with the coil again to complete the expansion of this position. Through the above cycle, the expansion of all parts of the circumferential direction of the coil is completed.

[0066] After the expansion is completed, the first servo motor 81 and the second servo motor 51 respectively drive the sliding seat 611 and the mounting frame 40 to move toward the coil placement position 21, and the lifting drive 70 drives the placement table 20 to descend, and then the expanded coil is disassembled and the next coil is installed.
