[0018] The embodiment of the present application provides an automatic shaft-pulling and shaft-loading device, as Figure 1As shown, the automatic shaft-pulling and shaft-uppering device 100 includes a frame 10, a lifting mechanism 20 arranged on the frame 10, a clamping mechanism 30 and an axis-shifting mechanism 40 arranged on the lifting mechanism 20, and the frame 10 supports the lifting mechanism 20, the clamping mechanism 30 and the axis-shifting mechanism 40 on the ground.

[0019] like Figure 1 , 5 As shown, the lifting mechanism 20 includes a lifting platform 1 that can move in the up-down direction and a lifting motor 2 for driving the lifting platform 1 to move. The lifting platform 1 is slidably arranged at the front side of the frame 10. A sliding assembly 3 is arranged between the lifting platform 1 and the frame 10. The sliding assembly 3 includes a lifting guide rail 31 extending in the up-down direction and a lifting slider 32 slidably matched with the lifting guide rail 31. The lifting guide rail 31 is fixedly arranged on the frame 10, and the lifting slider 32 is fixedly arranged on the lifting platform 1. The lifting motor 2 is fixedly arranged on the frame 10 and connected with the screw rod of the lifting platform 1. The output shaft of the lifting motor 2 is drivingly connected with a screw rod extending in the up-down direction. A sleeve that is matched with the screw rod is arranged on the lifting platform 1. When the screw rod rotates around its own axis under the drive of the lifting motor 2, the sleeve drives the lifting platform 1 to perform lifting and lowering motion along the screw rod. When the lifting mechanism 20 performs a shaft extraction operation or a shaft mounting operation in the automatic shaft extraction and shaft mounting device 100, the position of the clamping mechanism 30 is adjusted according to the position of the gas expansion shaft, so that the clamping mechanism 30 can be aligned with the gas expansion shaft.

[0020] like Figures 1-3 As shown, the clamping mechanism 30 includes at least one pair of clamping rollers for clamping the air-expanding shaft and a clamping cylinder 4 arranged on the lifting platform 1. In the embodiment of the present application, the clamping mechanism 30 includes an active clamping roller 51 and a passive clamping roller 52 arranged relatively front and back, and the passive clamping roller 52 is arranged on the front side of the active clamping roller 51. The active clamping roller 51 and the passive clamping roller 52 are parallel to each other and extend in the up and down directions. The active clamping roller 51 and the passive clamping roller 52 are arranged side by side on the right side of the lifting platform 1; the clamping cylinder 4 is transmission-connected to the active clamping roller 51 and the passive clamping roller 52 to drive the active clamping roller 51 and the passive clamping roller 52 to approach and move away from each other. The active clamping roller 51 and the passive clamping roller 52 approaching each other can clamp the air-expanding shaft in the coil.

[0021] The clamping mechanism 30 also includes a first clamping arm 61 and a second clamping arm 62 which are arranged opposite to each other in the front and rear directions. One end of the first clamping arm 61 is hinged to the cylinder body of the clamping cylinder 4, and the other end of the first clamping arm 61 is rotationally connected to the active clamping roller 51. The middle part of the first clamping arm 61 is rotationally connected to the lifting platform 1. The first clamping arm 61 is configured to rotate around a first center line X1 extending in the up-down direction under the drive of the clamping cylinder 4, and the first center line X1 passes through the middle part of the first clamping arm 61; one end of the second clamping arm 62 is hinged to the telescopic rod of the clamping cylinder 4, and the other end of the second clamping arm 62 is rotationally connected to the passive clamping roller 52. The middle part of the second clamping arm 62 is rotationally connected to the lifting platform 1. The second clamping arm 62 is configured to rotate around a second center line X2 extending in the up-down direction under the drive of the clamping cylinder 4, and the second center line X2 passes through the middle part of the second clamping arm 62. When the clamping cylinder 4 drives one end of the first clamping arm 61 and one end of the second clamping arm 62 to move away from each other, the active clamping roller 51 and the passive clamping roller 52 approach each other to clamp the air expansion shaft; when the clamping cylinder 4 drives one end of the first clamping arm 61 and one end of the second clamping arm 62 to move toward each other, the active clamping roller 51 and the passive clamping roller 52 move away from each other.

[0022] like Figures 2-5 As shown, the axis shifting mechanism 40 includes an axis shifting motor 7 arranged on the lifting platform 1. The axis shifting motor 7 is connected to the active clamping roller 51 to drive the active clamping roller 51 to rotate forward and reverse around its own axis. When the active clamping roller 51 and the passive clamping roller 52 clamp the air expansion shaft, the axis shifting motor 7 drives the active clamping roller 51 to rotate, so that the clamped air expansion shaft moves in the left and right directions under the transmission of the active clamping roller 51 to realize the shaft withdrawal operation or the shaft upper operation.

[0023] The lifting platform 1 includes an upper support plate 101 and a lower support plate 102 which are arranged opposite to each other in the upper and lower directions, and a connecting plate 103 which is perpendicular to the upper support plate 101 and the lower support plate 102. The upper support plate 101 is located on the upper side of the lower support plate 102, and the lifting slider 32 is fixed on the connecting plate 103. In order to avoid the mutual influence between the axis shifting motor 7 and the clamping cylinder 4, the axis shifting motor 7 is fixedly arranged on the upper support plate 101, the clamping cylinder 4 is arranged on the lower support plate 102, the first clamping arm 61 and the second clamping arm 62 are rotatably connected to the lower support plate 102, and the active clamping roller 51 and the passive clamping roller 52 are rotatably arranged on the right side of the lower support plate 102.

[0024] To achieve the transmission connection between the shift motor 7 and the active clamping roller 51, the shift mechanism 40 further includes a transmission structure that is transmission-connected between the shift motor 7 and the active clamping roller 51. This transmission structure includes a transmission shaft 81, a first chain transmission assembly 82, and a second chain transmission assembly 83. The transmission shaft 81 penetrates the upper support plate 101 in the up-and-down direction and can rotate around its own axis relative to the upper support plate 101 and the lower support plate 102. The first chain transmission assembly 82 is transmission-connected to the shift motor 7 and the transmission shaft 81. The first chain transmission assembly 82 includes a first sprocket 821 coaxially arranged with the output shaft of the shift motor 7, a second sprocket 822 coaxially arranged with the transmission shaft 81, and a first chain 823 connected between the first sprocket 821 and the second sprocket 822. The second chain transmission assembly 83 is transmission-connected to the active clamping roller 51 and the transmission shaft 81. The second chain transmission assembly 83 includes a third sprocket 831 coaxially arranged with the transmission shaft 81, a fourth sprocket 832 coaxially arranged with the active clamping roller 51, and a second chain 833 connected between the third sprocket 831 and the fourth sprocket 832. Both the second sprocket 822 and the third sprocket 831 are fixedly arranged with the transmission shaft 81 for coaxial rotation. The second sprocket 822 is located on the upper side of the upper support plate 101, and the third sprocket 831 is located on the lower side of the upper support plate 101. The transmission shaft 81 rotates around its own axis under the drive of the shift motor 7 through the transmission of the first chain transmission assembly 82. The third sprocket 831 rotates with the transmission shaft 81 and drives the active clamping roller 51 to rotate.

[0025] The shift motor 7 enables the active clamping roller 51 to rotate forward and backward around its own axis through forward and reverse rotations. The forward rotation of the active clamping roller 51 causes the air shaft clamped by the clamping mechanism 30 to be withdrawn from the coil, realizing the shaft withdrawal operation. The reverse rotation of the active clamping roller 51 causes the air shaft clamped by the clamping mechanism 30 to be fed into the equipment, realizing the shaft loading operation.

[0026] As Figure 1 、 2 shown, a baffle 9 is provided on the lifting platform 1. The baffle 9 includes a blocking portion 91 perpendicular to the upper support plate 101 and the lower support plate 102. The blocking portion 91 is located on the side of the active clamping roller 51 and the passive clamping roller 52 away from the lifting platform 1. When the shift mechanism 40 drives the active clamping roller 51 and the passive clamping roller 52 to perform the shaft withdrawal operation, the blocking portion 91 blocks the end of the coil, facilitating the shaft withdrawal operation and preventing the coil from being withdrawn with the air shaft, resulting in an uneven end face of the coil.

[0027] A chassis 50 is also provided on the frame 10. Various electrical components are accommodated in the chassis 50, reducing the floor area of the equipment and ensuring the beauty and safety of the equipment.

[0028] When the automatic shaft extraction and loading device 100 performs the shaft extraction operation, the lifting motor 2 adjusts the height of the lifting platform 1 according to the coil diameter of the coil, so that the end of the air shaft to be extracted is located between the active clamping roller 51 and the passive clamping roller 52. The clamping cylinder 4 drives the active clamping roller 51 and the passive clamping roller 52 to approach each other to clamp the air shaft. The shaft moving motor 7 drives the active clamping roller 51 to rotate forward to convey the air shaft along the axis of the air shaft itself and away from the coil. The blocking portion 91 abuts against the end of the coil until the air shaft is extracted. The shaft moving motor 7 stops, the clamping cylinder 4 resets, and the active clamping roller 51 and the passive clamping roller 52 separate to wait for the extraction of the next air shaft.

[0029] This application can adjust the height of the clamping roller according to different coil diameters, effectively avoid damage to the air shaft, and extend the service life of the air shaft; the clamping roller can rotate forward and backward to realize automatic shaft extraction and loading, with a wide range of applications, saving time and effort.

Those skilled in the art should understand that this application is not limited by the above embodiments.
