DETAILED DESCRIPTION

[0033] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 10 As shown, a coupling outer gear ring disassembly device comprises a first housing 1 and a second housing 2, the first housing 1 and the second housing 2 are fixedly connected, a placement groove 3 is provided inside the first housing 1 and the second housing 2, and a hydraulic rod 4 is fixedly installed inside the placement groove 3;

[0035] A plurality of connection components 6 for adjusting the length are fixedly mounted on the outer side of the second housing 2 , and a limiting component 7 for fixing the outer gear ring is rotatably mounted on the outer side of each connection component 6 .

[0036] In this embodiment, the connecting assembly 6 includes a first transmission opening 601 , which is opened through the outer surface of the second housing 2 , an expansion shell 604 is fixedly installed outside the first transmission opening 601 , and a connecting sleeve 6041 is fixedly installed in the middle of the expansion shell 604 .

[0037] In the specific setting, guide rails 9 are fixedly installed on the inner walls of the upper and lower side mounting grooves 3, and a worm sleeve 602 is rotatably installed between the two guide rails 9. The upper and lower ends of the worm sleeve 602 are provided with guide grooves 6021 for matching the guide rails 9, and the upper side of the outer surface of the worm sleeve 602 is provided with a plurality of tooth grooves 6022.

[0038] A worm wheel 6042 is rotatably mounted inside the expansion shell 604 , one side of the worm wheel 6042 is meshed with the worm sleeve 602 , and a second transmission port 6043 is formed through one side of the expansion shell 604 .

[0039] The worm sleeve 602 rotates, so that the surface of the worm sleeve 602 meshes with one side of the worm wheel 6042 through the first transmission port 601, so that several worm wheels 6042 on the outside can rotate simultaneously, and then the worm wheel 6042 can adjust the length of the column 702, thereby adjusting the fixed distance to adapt to external gear rings of different sizes and installation positions.

[0040] The outer surface of the first housing 1 is provided with a third transmission opening 603 , a rotating frame 6031 is fixedly installed outside the third transmission opening 603 , a driving motor 6032 is fixedly installed on the upper end of the rotating frame 6031 , a driving gear 6033 is fixedly installed on the output end of the driving motor 6032 , and the driving gear 6033 is meshed with the tooth groove 6022 .

[0041] By starting the driving motor 6032, the driving gear 6033 can be driven to rotate inside the rotating frame 6031. During the rotation of the driving gear 6033, the driving gear 6033 is used to pass through the third transmission port 603 and engage with the tooth groove 6022, so that the worm sleeve 602 can achieve continuous rotation under the cooperation between the guide groove 6021 and the guide rail 9. The above structure can realize the rapid adjustment of the extension length of the column 702. Compared with the one-by-one adjustment of the existing device, the present application is more efficient in the adjustment process.

[0042] In the specific setting, the limiting component 7 includes a flip frame 701, a connecting rotating rod 7011 is fixedly installed on one side of the flip frame 701, and an adjusting through hole 7014 is opened on the other side of the flip frame 701. The connecting rotating rod 7011 is rotatably installed inside the connecting sleeve 6041, and a column 702 is slidably installed inside the adjusting through hole 7014, and a horse claw 703 is fixedly installed at the lower end of the column 702.

[0043] In the present application, a mounting groove 7012 is formed through the middle of the connecting rotating rod 7011 , a coil spring 7013 is fixedly installed inside the mounting groove 7012 , and the outer side of the coil spring 7013 is fixedly connected to the inner wall of the connecting sleeve 6041 .

[0044] By rotating the connecting rotating rod 7011 installed inside the connecting sleeve 6041, each flip frame 701 can be flipped freely, so that it can cooperate with the extension of the column 702, so that the claw 703 can be stuck on the outside of the outer gear ring. During the sticking process, in order to prevent the flip frame 701 from turning outward, a coil spring 7013 is set between the connecting sleeve 6041 and the connecting rotating rod 7011, so that each connecting rotating rod 7011 is flipped inward by default, thereby ensuring stability during disassembly.

[0045] In the specific configuration, an extension plate 7021 is fixedly mounted on one side of the column 702 , a rack 7022 is fixedly mounted on the surface of the extension plate 7021 , and the rack 7022 passes through the second transmission opening 6043 and meshes with the worm gear 6042 .

[0046] When the worm gear 6042 rotates, it meshes with the rack 7022, so that the rack 7022 drives the column 702 to slide freely inside the adjusting hole 7014, thereby adjusting the extension length of the column 702. In order not to affect the normal fixation of the present application, the column 702 is arranged in the adjusting hole 7014, and the column 702 is consistent with the flipping axis of the flip frame 701, so that the rack 7022 will also be adjusted along the worm gear 6042 during flipping, and will not affect the adjustment of the column 702.

[0047] It should be noted that a groove 7031 is formed at the end of the claw 703 , a mounting rod 7032 is fixedly installed inside the groove 7031 , a swing frame 7033 is rotatably installed on the mounting rod 7032 , and a bonding plate 7034 is fixedly installed at one end of the swing frame 7033 .

[0048] In order to avoid damage to the outer gear ring during disassembly due to a small extrusion area, a swing frame 7033 is rotatably installed on the claw 703, so that the bonding plate 7034 can be bonded at a corresponding angle according to the current outer gear ring surface, thereby increasing the contact area and reducing the impact on the outer gear ring surface when force is applied later.

[0049] The output end of the hydraulic rod 4 is fixedly mounted with an ejector plate 5 , and flanges 8 are provided on the outer sides of the first shell 1 and the second shell 2 , and the first shell 1 and the second shell 2 are fixed by the flanges 8 .

[0050] In the present application, the worm wheel 6042 can mesh with the worm sleeve 602 and the rack 7022 .

[0051] The working principle of the coupling outer gear ring disassembly device:

[0052] When in use, first adjust the length of the column 702 as needed, wherein the driving motor 6032 is started to drive the driving gear 6033 to rotate inside the rotating frame 6031, and during the rotation of the driving gear 6033, the driving gear 6033 is used to pass through the third transmission port 603 and engage with the tooth groove 6022, so that the worm sleeve 602 can achieve continuous rotation under the cooperation between the guide groove 6021 and the guide rail 9;

[0053] Then, the worm sleeve 602 rotates, so that the surface of the worm sleeve 602 meshes with one side of the worm wheel 6042 through the first transmission port 601, so that the outer worm wheels 6042 can rotate simultaneously. Finally, when the worm wheel 6042 rotates, it meshes with the rack 7022, so that the rack 7022 drives the column 702 to slide freely inside the adjustment through hole 7014, so as to adjust the extension length of the column 702.

[0054] After the adjustment is completed, the column 702 is pulled as needed, and each flip frame 701 can be flipped freely by rotating the connecting rod 7011 installed inside the connecting sleeve 6041, so that the claw 703 can be stuck on the outside of the outer gear ring, and the claw 703 is fixed in turn. When fixing, the coil spring 7013 is set between the connecting sleeve 6041 and the connecting rod 7011, so that each connecting rod 7011 is flipped inward by default to prevent the flip frame 701 from flipping outward;

[0055] After the fixation is completed, the ejection plate 5 is pushed by starting the hydraulic rod 4 so that the ejection plate 5 fits the external mounting shaft, and then the ejection plate 5 is continuously pushed. Under its action, the claw 703 can be controlled to be pulled outward to pull the outer gear ring from the mounting shaft. During the pulling-out process, the swing frame 7033 is rotated on the claw 703, so that the fitting plate 7034 can fit at a corresponding angle according to the current surface of the outer gear ring, thereby increasing the contact area and reducing the impact on the surface of the outer gear ring. Finally, the outer gear ring is removed under the continuous push of the hydraulic rod 4.

[0056] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
