[0023] The following describes exemplary embodiments of the present disclosure in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0024] like Figures 1 to 8 As shown, an embodiment of the present invention provides a device for removing a bad bearing inner ring, comprising a workbench 101, a threaded rod 102 is provided above the workbench 101, and includes: A power platform 201 is provided above the workbench 101. A telescopic sleeve 207 is provided above the power platform 201. The threaded rod 102 is movably provided on the surface of the telescopic sleeve 207. The threaded rod 102 is rotated by the rotation of the telescopic sleeve 207. A gripper box 301 is provided on the bottom surface of the workbench 101. A gripper box 301 is provided on the bottom surface of the gripper box 301. A plurality of claw hooks 304 are provided in a circular array inside the gripper box 301. The claw hooks 304 are used to hook the inner edge of the bottom end surface of the inner ring of the damaged bearing. An auxiliary box 401 is provided below the gripper box 301. Inside the auxiliary box 401, a circular array of moving blocks 402 are provided. A plurality of auxiliary wheels 403 are mounted on the surface of the moving blocks 402. The surface of the moving blocks 402 is provided with an inclined groove 404. The bottom of the auxiliary box 401 is provided with a conical threaded block 406 that matches the inclined groove 404. A number of guide blocks 502 are arranged in a circular array above the workbench 101. Guide grooves are provided on the bottom surfaces of the guide blocks 502. A push rod 508 is provided below the guide blocks 502. The push rod 508 rotates along the central axis of the bottom surface of the guide blocks 502, so that the guide blocks 502 reciprocate in the vertical direction, so that the threaded rod 102 vibrates periodically along the axial direction.

[0025] In the embodiment of the present invention, the shaft 103 to be removed with the defective inner ring of the bearing is passed upward from the bottom of the tapered threaded block 406. During the insertion process, the shaft 103 to be removed pushes the moving block 402 with the auxiliary wheels 403 toward the periphery of the shaft 103 to be removed, so that the wheel bodies of the auxiliary wheels 403 are all in contact with the shaft 103 to be removed. As the shaft 103 to be removed continues to move upward, the shaft 103 to be removed and the defective inner ring 104 are pushed away from the periphery of the shaft 103 by the inclined surface of the claw hook 304 until the claw hook 304 hooks the inner edge of the bottom end surface of the defective inner ring 104. At this time, the shaft to be removed 103 is released, and the conical threaded block 406 is moved upward inside the auxiliary box 401. The cooperation between the conical threaded block 406 and the bevel groove 404 causes the auxiliary wheel 403 to press toward the shaft to be removed 103. The shaft to be removed 103 is kept in a vertical state under the uniform pressure of the auxiliary wheel 403, that is, the central axis of the threaded rod 102 and the central axis of the shaft to be removed 103 are kept coincident, thereby reducing harmful bending moment and lowering the threshold of the separation force applied during the separation process of the inner ring of the bad bearing and the lead screw; In the process of pressing the threaded rod 102 downward, the telescopic sleeve 207 is extended and retracted to adapt to threaded rods 102 of different lengths. The threaded rod 102 moves downward in a spiral, driving the push rod 508 along the guide groove on the bottom surface of the push rod 508 to make the guide block 502 reciprocate in the vertical direction, causing the threaded rod 102 to generate periodic vibration in the vertical direction.

[0026] The bottom surface of the power platform 201 is fixedly connected to a number of support columns 202 in a circular array, and the support columns 202 are fixedly connected to the workbench 101. The surface of the power platform 201 is fixedly connected to the support platform 203. The bottom surface of the support platform 203 is provided with four gears 204 in a circular array. The gears 204 are rotatably connected to the tubular protrusion corresponding to the bottom surface of the support platform 203 through a first bearing. The surface of the power platform 201 is rotatably connected to a gear ring 205 through a second bearing. The gears 204 are all meshed with the gear ring 205. The telescopic sleeve 207 is fixedly connected to the surface of the gear ring 205. A drive motor 206 is installed on the surface of the support platform 203. The output shaft of the drive motor 206 is fixedly connected to one of the gears 204 through a first reserved hole opened on the surface of the support platform 203.

[0027] The top of the telescopic sleeve 207 is closed, the bottom of the telescopic sleeve 207 is through-shaped, the top of the threaded rod 102 is fixedly connected to a hexagonal block, the upper surface of the telescopic sleeve 207 is provided with a hexagonal groove 208, the threaded rod 102 is embedded in the inside of the hexagonal groove 208 through the hexagonal block, the surface of the hexagonal groove 208 is provided with a first through-groove, the upper surface of the telescopic sleeve 207 is threadedly connected to a threaded cover 209, and the inner top surface of the threaded cover 209 conflicts with the hexagonal block at the top of the threaded rod 102.

[0028] In the embodiment of the present invention, the power platform 201 is fixed to the workbench 101 via the support column 202. When removing the inner ring of the defective bearing, the positional relationship between the shaft 103 to be removed and the defective inner ring 104 is determined based on the specifications of the screw with the defective bearing inner ring and the positional relationship between the shaft 103 to be removed and the defective inner ring 104. For example, if the defective inner ring 104 is located in the middle of the shaft 103 to be removed, a longer threaded rod 102 can be used. If the threaded rod 102 is located near the end of the surface of the shaft 103 to be removed, a shorter threaded rod 102 can be used. Select a suitable threaded rod 102, unscrew the threaded cap 209 on the surface of the telescopic sleeve 207, and vertically insert the threaded rod 102 into the first through hole inside the hexagonal prism groove 208 on the top of the telescopic sleeve 207. The hexagonal block of the threaded rod 102 is embedded in the hexagonal prism groove 208 on the surface of the telescopic sleeve 207. At this time, tighten the threaded cap 209 on the surface of the telescopic sleeve 207 so that the inner top surface of the threaded cap 209 is in close contact with the hexagonal block of the threaded rod 102 to maintain the stability of the threaded rod 102. When the threaded rod 102 is rotated, the drive motor 206 is started, and the operation of the drive motor 206 is driven by the gear 204 and the gear ring 205, so that the gear ring 205 and the gear 204 are rotated. The rotation of the gear ring 205 causes the telescopic sleeve 207 to drive the threaded rod 102 to rotate. The gripper box 301 is fixedly connected to the bottom surface of the workbench 101. The interior of the gripper box 301 is fixedly connected to a number of first spring rods 302 in a circular array. The claw hooks 304 are respectively fixedly connected to the ends of the corresponding first spring rods 302. The surfaces of the telescopic rods of the first spring rods 302 are fixedly connected to support blocks 303. The support blocks 303 are in contact with the internal top surface and internal bottom surface of the gripper box 301.

[0029] The hook portion of the claw hook 304 is vertically upward, and the bottom surface of the claw hook 304 is an inclined surface.

[0030] In the embodiment of the present invention, when the shaft 103 to be taken is passed from bottom to top into the interior of the clamping claw box 301, the shaft 103 to be taken and the bad inner ring 104 pass through the inclined surface of the claw hook 304, so that the claw hook 304 moves in the direction of squeezing the corresponding first spring rod 302. When the bad inner ring 104 slides over the inclined surface of the claw hook 304, the claw hook 304 moves in the direction of the shaft 103 to be taken under the action of the elastic potential energy of the first spring rod 302, at which time the shaft 103 to be taken moves downward, and the hook portion of the claw hook 304 hooks on the inner edge of the bottom end surface of the bad inner ring 104. When the threaded rod 102 presses the shaft 103 downward, the support block 303 contacts the inner top and bottom surfaces of the clamping box 301 , so that the claw hook 304 on the first spring rod 302 is stably hooked on the bottom of the broken inner ring 104 .

[0031] The auxiliary box 401 is threadedly connected to the surface of the clamping box 301, and the moving block 402 fits with the inner bottom surface of the auxiliary box 401 and the bottom surface of the clamping box 301. A number of second spring rods 405 are evenly fixedly connected to the surface of the moving block 402, and the ends of the second spring rods 405 away from the moving block 402 are fixedly connected to the auxiliary box 401. The conical thread block 406 is threadedly connected to the first thread groove opened on the bottom surface of the auxiliary box 401, and the interior of the conical thread block 406 is provided with a curved surface corresponding to the bevel groove 404.

[0032] In an embodiment of the present invention, during the process of the shaft 103 to be taken passing into the auxiliary box 401 from bottom to top, the shaft 103 to be taken and the broken inner ring 104 cause the auxiliary wheel 403 to drive the moving block 402 to move in the direction of squeezing the second spring rod 405. When the broken inner ring 104 is hooked by the claw hook 304, the conical threaded block 406 is tightened upward at the bottom of the auxiliary box 401, so that the curved surface of the conical threaded block 406 continuously squeezes the moving block 402 through the inclined groove 404. Because the moving block 402 is in contact with the inner bottom surface of the auxiliary box 401 and the bottom surface of the clamping claw box 301, the moving block 402 drives the auxiliary wheel 403 to move in the direction of squeezing the shaft 103 to be taken. Under the uniform squeezing of the auxiliary wheels 403 in a ring array around the shaft 103 to be taken, the shaft 103 to be taken remains in a vertical state, which is convenient for squeezing the threaded rod 102.

[0033] In another preferred embodiment of the present invention, when the shaft 103 to be taken is short, the auxiliary box 401 can be rotated and separated on the surface of the gripper box 301 to allow the shaft 103 to be taken to pass directly into the bottom of the gripper box 301 .

[0034] A T-shaped threaded cylinder 504 is arranged between the workbench 101 and the power platform 201. The T-shaped threaded cylinder 504 is threadedly connected to the surface of the threaded rod 102. The surface of the T-shaped threaded cylinder 504 is slidably connected to the hammer cylinder 505. The bottom surface of the gear 204 is fixedly connected to the first rotating rod 501. The first rotating rod 501 extends to the bottom of the power platform 201 through the second reserved hole opened on the surface of the power platform 201. The first rotating rod 501 is rotatably connected to the surface of the workbench 101 through the third bearing. The surface of the first rotating rod 501 is fixedly connected to the fixed round block 503. The surface of the T-shaped threaded cylinder 504 is provided with four second connecting rods 507 in a circular array. The second connecting rod 507 is rotatably connected to the corresponding fixed round block 503 through the fourth bearing.

[0035] The guide block 502 is rotatably connected to the surface of the corresponding first rotating rod 501, and the surface of the hammer cylinder 505 is fixedly connected to four first connecting rods 506 in a circular array. The first connecting rods 506 are respectively fixedly connected to the corresponding guide block 502, and the surface of the fixed round block 503 is fixedly connected to the top rod 508.

[0036] The guide groove includes at least two inclined surface portions 5021 , and both sides of the inclined surface portion 5021 are provided with a flat surface portion 5022 and a vertical surface portion 5023 .

[0037] In the embodiment of the present invention, the threaded rod 102 passes through the bottom of the power platform 201 and enters the interior of the T-shaped threaded barrel 504. At this time, the threaded rod 102 is rotated so that the threaded rod 102 is threadedly connected to the interior of the T-shaped threaded barrel 504. When the telescopic sleeve 207 drives the threaded rod 102 to rotate, the threaded rod 102 spirally moves downward inside the T-shaped threaded barrel 504. The T-shaped threaded barrel 504 is kept relatively stationary with the power platform 201 through the second connecting rod 507, the fixed round block 503 and the first rotating rod 501, so that the threaded rod 102 remains stable during the downward movement, that is, the threaded rod 102 and the central axis of the shaft to be removed 103 are stably coincident. When the drive motor 206 is running, the first rotating rod 501 is rotated through the transmission between the gear 204 and the gear ring 205. The rotation of the first rotating rod 501 drives the fixed round block 503 to rotate. The rotation of the fixed round block 503 causes the top rod 508 to slide continuously along the guide groove at the bottom of the guide block 502. During the sliding process, when the top rod 508 slides along the inclined surface 5021, the guide block 502 moves upward along the surface of the first rotating rod 501. When the top rod 508 slides over the inclined surface 5021 and slides to the surface of the vertical surface 5023, the guide block 502 moves downward along the first rotating rod 501 under the action of gravity. When the top rod 508 slides to the surface of the flat surface 5022, the guide block 502 does not move vertically on the surface of the first rotating rod 501. When the guide block 502 makes reciprocating motion in the vertical direction on the surface of the first rotating rod 501, the hammer cylinder 505 keeps moving synchronously with the guide block 502 through the first connecting rod 506. When the guide block 502 falls to the lowest point on the surface of the first rotating rod 501, the hammer cylinder 505 hits the surface of the T-shaped threaded cylinder 504, causing the threaded rod 102 to produce periodic vibration.

[0038] In another preferred embodiment of the present invention, in order to increase the impact force of the hammer cylinder 505 on the T-shaped threaded cylinder 504, the length of the push rod 508 can be adjusted so that when the push rod 508 slides to the surface of the vertical surface portion 5023, the guide block 502 moves downward along the surface of the first rotating rod 501 under the action of gravity until the hammer cylinder 505 hits the surface of the T-shaped threaded cylinder 504. At this time, the push rod 508 does not contact the flat portion 5022. When the push rod 508 slides to the surface of the inclined portion 5021, the guide block 502 continues to move upward on the surface of the first rotating rod 501.

[0039] It should be noted that the surface of the gripper box 301 is provided with a flange. When the auxiliary box 401 is screwed onto the surface of the gripper box 301 and the flange on the surface of the auxiliary box 401 conflicts with the flange on the surface of the gripper box 301, the moving block 402 fits against the bottom surface of the gripper box 301.

[0040] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
