[0039] like Figure 1 and Figure 2 As shown, the present invention provides a shaft structure disassembly device 1, which includes a mounting base assembly 100, a lifting mechanism 200, a clamping assembly 300, and a connecting assembly 400. The fixed portion of the lifting mechanism 200 is mounted on the mounting base assembly 100, and the movable portion of the lifting mechanism 200 is movable relative to the mounting base assembly 100 along its first axis; the clamping assembly 300 includes a plurality of clips 310, which are evenly arranged around the first axis and are movable along the radial direction of the lifting mechanism 200; the mounting base assembly 100 is connected to the clamping assembly 300 via the connecting assembly 400, and the mounting base assembly 100 is movable relative to the clamping assembly 300 along the first axis.

[0040] Specifically, before use, the movable portion of the lifting mechanism 200 is close to its fixed portion, the clips 310 of the clamping assembly 300 are away from each other along the radial direction of the lifting mechanism 200, the mounting seat assembly 100 is located outside the end of the shaft structure 3, the movable portion of the lifting mechanism 200 is in contact with the axial end face of the shaft structure 3, and the axis of the lifting mechanism 200 is kept parallel to the axis of the shaft structure 3, the relative position of the mounting seat assembly 100 and the clamping assembly 300 is adjusted, the clamping assembly 300 extends along the axial direction of the shaft structure 3, and the clamping assembly 300 is sleeved. When on the outside of the ring structure 2, the clips 310 approach each other radially along the lifting mechanism 200 and abut against the ring structure 2 and lock the relative position of the clips 310, completing the locking of the ring structure 2 by the clamping assembly 300, starting the lifting mechanism 200, and the movable part of the lifting mechanism 200 moves axially away from its fixed part. The force is transmitted to the ring structure 2 through the mounting seat assembly 100, the connecting assembly 400 and the clamping assembly 300, causing the ring structure 2 and the shaft structure 3 to undergo axial relative movement, and the ring structure 2 is withdrawn from the axial end of the shaft structure 3.

[0041] In this way, the adjustment of the mounting seat assembly 100 and the clamping assembly 300 can meet the use requirement of the shaft structure disassembly device 1 to grasp the ring structure 2 at different distances from the axial end face of the shaft structure 3, and the adjustment between the clips 310 in the clamping assembly 300 can meet the requirements of the shaft structure disassembly device 1 for grasping the ring structure 2 with different shaft diameters, making the shaft structure disassembly device 1 more versatile.

[0042] Preferably, when in use, the axis of the lifting mechanism 200 and the axis of the shaft structure 3 are located in the same straight line.

[0043] Optionally, the connecting assembly 400 includes a first threaded member 410 and a first nut 420. A plurality of first threaded members 410 are provided, and the plurality of first threaded members 410 are evenly distributed around the axis of the jacking mechanism 200. The mounting seat assembly 100 and / or the clamping assembly 300 are slidably sleeved on the first threaded member 410 and can be relatively close to or away from each other along the axial direction of the jacking mechanism 200. The first nut 420 is threadedly connected to the first threaded member 410 for adjusting the maximum axial spacing between the mounting seat assembly 100 and the clamping assembly 300 on the jacking mechanism 200.

[0044] Therefore, the first threaded members 410 evenly distributed around the axis of the jacking mechanism 200 can provide stable guiding effect for the relative movement of the mounting base assembly 100 and the clamping assembly 300, and when the clamping assembly 300 completes clamping on the ring structure 2 and the jacking mechanism 200 exerts force on the shaft structure 3 along the axis of the shaft structure 3, the force exerted by the jacking mechanism 200 on the mounting base assembly 100 can be evenly distributed to the first threaded members 410. By the threaded connection of the first nuts 420 and the first threaded members 410, the maximum axial distance between the mounting base assembly 100 and the clamping assembly 300 on the jacking mechanism 200 can be adjusted, which is simple in structure and convenient to operate.

[0045] For example, in the embodiment, the first threaded members 410 are threaded studs, two first nuts 420 are threaded on the threaded studs, one end of the threaded studs penetrates the mounting base assembly 100 and is connected with one of the first nuts 420 on the side of the mounting base assembly 100 facing away from the clamping assembly 300, the other end of the threaded studs penetrates the clamping assembly 300 and is connected with the other first nut 420 on the side of the clamping assembly 300 facing away from the mounting base assembly 100, the area between the mounting base assembly 100 and the clamping assembly 300 and the two first nuts 420 can change the size range by rotating the first nut 420 on one side, thereby limiting the maximum distance between the mounting base assembly 100 and the clamping assembly 300.

[0046] It should be noted that the first nut 420 cannot pass through the mounting base assembly and / or the clamping assembly 300, that is, the minimum radial dimension of the first nut 420 is greater than the minimum hole diameter of the first avoiding hole of the mounting base assembly 100 for penetrating the first threaded member 410, and / or greater than the minimum hole diameter of the second avoiding hole of the clamping assembly 300 for penetrating the first threaded member 410.

[0047] In other embodiments, the first threaded member 410 is a screw, which includes a screw cap and a screw rod. Optionally, the screw rod penetrates the mounting base assembly 100 and the clamping assembly 300 in sequence and is threaded with the first nut 420, and the mounting base assembly 100 and the clamping assembly 300 are both slidably sleeved on the screw rod between the first nut 420 and the screw cap.

[0048] In other embodiments, one of the mounting base assembly 100 and the clamping assembly 300 is fixed with the first threaded member 410, and the other is slidably sleeved outside the first threaded member 410.

[0049] Preferably, the first threaded member 410 is connected with the clamping piece 310, and the first threaded member 410 and the clamping piece 310 are one-to-one corresponding.

[0050] Optionally, the mounting base assembly 100 includes a first support member 110 and a second support member 120. The fixed portion of the lifting mechanism 200 is connected to the first support member 110, and the second support member 120 is used to mount the connecting assembly 400. The first support member 110 and the second support member 120 are detachably connected. In this way, if one of the first support member 110 and the second support member 120 is damaged, only the corresponding one needs to be replaced, which can avoid waste of resources.

[0051] Optionally, the second support member 120 is provided with a plurality of reinforcing ribs 121 , which are evenly distributed around the axis of the lifting mechanism 200 to form a placement groove, and the first support member 110 is inserted into the placement groove, and the reinforcing ribs 121 can squeeze the first support member 110 . Specifically, multiple reinforcing ribs 121 are radially arranged with the axis of the jacking mechanism 200 as the center, forming a placement groove at the center position, and the first support member 110 is installed in the placement groove. When the shaft structure disassembly device 1 is in operation, the jacking mechanism 200 gives the first support member 110 a force pointing to the side away from the shaft structure 3, and the first support member 110 transmits the force to the center position of the second support member 120, and the peripheral side of the second support member 120 is relatively fixed to the ring structure 2 through the connecting component 400 and the clamping component 300. The middle part of the second support member 120 is deformed relative to its peripheral side toward the side away from the shaft structure 3. At this time, the reinforcing ribs 121 squeeze the first support member 110, and the first support member 110 supports the second support member 120 through the reinforcing ribs 121 to suppress the deformation trend of the second support member 120.

[0052] Optionally, the second support member 120 includes a plurality of second support sub-members, each of which is connected to the first support member 110, and each of which is connected to at least one first threaded member 410. In this way, when a second support sub-member is damaged, only the corresponding second support sub-member needs to be replaced, which can further avoid waste of resources.

[0053] Specifically, multiple second support sub-components are evenly arranged around the first axis and are arranged one-to-one corresponding to the first threaded member 410. A second support sub-component is installed on each reinforcing rib 121, and multiple second support sub-components are respectively connected to the first support member 110 through fasteners.

[0054] Optionally, the first support member 110 and the second support member 120 are connected by threaded fasteners. With this arrangement, the connection structure is simple, and the assembly of the shaft structure disassembly device 1 is facilitated.

[0055] Optionally, the mounting seat assembly 100 is provided with a waist-shaped hole 122 , and the first threaded member 410 is slidably inserted into the waist-shaped hole 122 and can move closer to or away from the lifting mechanism 200 along the waist-shaped hole 122 .

[0056] For example, the waist-shaped holes 122, the first threaded member 410 and the clips 310 are arranged in a one-to-one correspondence, and multiple waist-shaped holes 122 are radially opened with the axis of the lifting mechanism 200 as the center. In this way, the relative positions between the clips 310 are adjusted by moving the first threaded member 410 relative to the mounting seat assembly 100.

[0057] Optionally, the clamping assembly 300 also includes a second threaded member 320 and a second nut 330. Two circumferentially adjacent clips 310 of the lifting mechanism 200 are connected by the second threaded member 320. At least one of the two clips 310 is slidably sleeved on the second threaded member 320. The second nut 330 is threadedly connected to the second threaded member 320. The second threaded member 320 is used to adjust the maximum spacing between the two clips 310.

[0058] Exemplarily, the second threaded member 320 is a stud, which is threadedly connected to two second nuts 330. The two clips 310 are located in the area between the two second nuts 330. The range of the area can be adjusted by screwing the second nut 330 on one side, thereby limiting the maximum spacing between the two clips 310.

[0059] Before use, the two second nuts 330 are relatively far apart, and the maximum distance between the two clips 310 is relatively large, so that the clamping assembly 300 can be opened. When the clips 310 are in contact with the ring structure 2, the distance between the two second nuts 330 is reduced until the two second nuts 330 are in contact with the two clips 310 respectively to lock the relative positions between the clips 310, thereby completing the clamping assembly 300's clamping action on the ring structure 2.

[0060] Optionally, a buffer member 340 is installed on the side of the clip 310 facing the axis of the lifting mechanism 200 , and the buffer member 340 can be elastically deformed in the radial direction of the lifting mechanism 200 .

[0061] In this way, the buffer member 340 can achieve soft contact between the clip 310 and the ring structure 2 , thereby preventing the clip 310 and the ring structure 2 from being scratched or worn.

[0062] Furthermore, the friction coefficient of the buffer 340 is greater than the friction coefficient of the clip 310 , thereby increasing the friction between the clamping assembly 300 and the ring structure 2 , thereby preventing the clamping assembly 300 and the ring structure 2 from loosening when the lifting mechanism 200 is operating.

[0063] Optionally, the buffer member 340 is a rubber member.

[0064] Optionally, the clip 310 includes an abutment portion. When the clamping assembly 300 fixes the ring structure 2, the abutment portion of the clip 310 is located on the side of the ring structure 2 facing away from the mounting seat assembly 100. When the lifting mechanism 200 applies a force to the shaft structure 3, the abutment portion of the clip 310 can abut against the axial end face of the ring structure 2. In this way, the clamping assembly 300 can ensure that it can firmly grasp the ring structure 2.

[0065] Furthermore, the above are merely preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will appreciate that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions are possible for those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments and may include many other equivalent embodiments without departing from the scope of the present invention. The scope of the present invention is determined by the scope of the appended claims.
