Description

Technical Field

[0001] The invention belongs to the field of bearing disassembly and assembly, in particular to a rolling mill shaft disassembly and assembly device. Background Art

[0002] Rolling mill bearings are used in the rolling industry, specifically for rolling nonferrous, ferrous, and non-metallic products. They are used at the roller diameter and on the drum of the rolling roller system. Four-row cylindrical roller bearings are typically used to carry radial loads, while thrust roller or thrust ball bearings, as well as radial angular contact ball bearings and radial roller bearings, carry axial loads. During rolling mill operation, the inner ring of these bearings rotates while the outer ring remains stationary. Due to this kinematic characteristic, the outer ring's load area remains fixed. To extend the service life of rolling mill bearings, the outer ring assembly must be removed from the seat after a period of use to change the load area.

[0003] A patent application with publication number CN107457737A discloses a rolling mill bearing disassembly and assembly tool, which belongs to the technical field of rolling mill bearing maintenance equipment. It includes a base, two sliders slidably connected to the two ends of the base, a connecting rod fixed to the base at one end, a rotating sleeve sleeved on the connecting rod, a positioning plate fixed to the upper part of the connecting rod, a bearing pressure plate and a lifting ring; a handle is fixed to the upper part of the rotating sleeve, and two sets of connecting rod mechanisms are symmetrically fixed at both ends of any diameter of the lower part of the rotating sleeve, and the bottom surface of the bearing pressure plate coincides with the upper surface of the positioning plate; the lifting ring is threadedly connected to the upper end of the connecting rod. The present invention uses a rocker slider mechanism to quickly and easily complete the disassembly and assembly of rolling mill bearings, thereby improving the disassembly and assembly efficiency; at the same time, it avoids the scattering of multi-row bearings during the disassembly and assembly process, greatly improving the safety of bearing disassembly and assembly.

[0004] It can be seen from this that the above-mentioned device can clamp the bearings and disassemble them after clamping, but the bearing disassembly device needs to be manually adjusted during use, because bearings that have been used for a long time are difficult to disassemble, and bearings of different sizes cannot be easily changed in extension angle, and are easy to bend during use.

[0005] To this end, the present invention provides a rolling mill shaft disassembly and assembly device. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve the technical problem is as follows: a rolling mill shaft disassembly and assembly device according to the present invention includes an adjusting rotary column rollingly mounted on a base support frame, a plurality of teeth are provided inside the adjusting rotary column, and a moving component is rollingly connected to the outer wall of the adjusting rotary column, and the moving component includes:

[0008] The limit slider is slidably connected to the outer wall of the adjusting rotating column. The outer wall of the limit slider is installed with multiple support columns, and the outer wall of the support column is fixedly installed with a limit ring;

[0009] The gear train is fixedly mounted on the gear unit and the gear is mounted on a pin of the gear train, and the pin is mounted on a pinion gear of the gear train, and the pinion gear is mounted on a pinion gear of the gear train. Adjust the spherical teeth and move the outer wall of the spherical teeth to engage with the annular rack. Before disassembling the rolling mill bearing, first adjust the position of the limit ring and adjust the limit ring to the outside of the disassembly. Then move the clamping moving block to the inner wall of the rolling mill bearing away from the limit ring, and start preparing to disassemble the bearing. Rotate the annular rack on the side wall of the rotating gear circle block. The annular rack rotates, and the rotation of the annular rack drives the spiral texture to rotate, and the spiral texture engages with the thread on the surface of the telescopic arm, thereby extending multiple telescopic arms outward with the rotating gear circle block as the center, thereby limiting the rolling mill bearing, and then rotate the worm gear. The worm gear engages with the teeth, thereby driving the second transmission rod to move along the adjusting rotating column to the side of the base support frame, thereby pulling the bearing out of the support frame, and completing the disassembly and assembly of the bearing.

[0010] Preferably, the outer wall of the limit slider is slidably connected to a support sliding post, and the outer wall of the support sliding post is fixedly connected to a spring support block, and the support sliding post passes through the limit ring and is movably connected to the inside of the limit ring, and the outer wall of the support sliding post is provided with a limit spring, and the limit spring is located at the spring support block and the inner wall of the limit ring. When the limit ring needs to be limited and fixed, it is necessary to hold the support sliding post and slide the support sliding post outward until the support sliding post is moved out of the inside of the support post to adjust the extension length of the support sliding post and the position of meshing with the teeth. When adjusted to a suitable position, the support sliding post can be released. The support sliding post moves inward under the drive of the limit spring, thereby meshing with the teeth, completing the meshing of the adjusting rotating post. This device can effectively adjust the angle of engagement of the bearing support with the outer wall of the bearing ring, thereby facilitating the disassembly of the bearing.

[0011] Preferably, the internal rolling connection of the adjusting rotating column is provided with a transmission structure, the transmission structure includes a first transmission rod rollingly connected to the inside of the adjusting rotating column, a locking cylinder is fixedly installed on the end of the first transmission rod, and the end of the locking cylinder worm gear is fixedly connected to the worm gear, and the worm gear and the first transmission rod are rotationally connected through the locking adjusting column. When the first transmission rod is rotated, the first transmission rod and the locking cylinder drive the locking adjusting column to rotate, and the rotation of the locking adjusting column drives the worm gear to rotate. The rotation of the worm gear thereby drives the moving adjusting helical teeth to engage with the helical teeth on the outer wall of the second transmission rod, completing the engagement and rotation of the moving adjusting circular teeth, and the rotation of the moving adjusting circular teeth drives the annular rack on the side wall of the rotating tooth circle block to engage, thereby driving the rotating tooth circle block to rotate. This device facilitates the clamping and movement of the bearing.

[0012] Preferably, the outer wall end of the second transmission rod is rollingly connected to the impact device, the impact device includes a rotating plate fixedly connected to the outer wall of the second transmission rod, the side wall of the rotating plate is fixedly connected to the triangular block, the outer wall of the second transmission rod is slidingly connected to the impact plate, one side wall of the impact plate is fixedly connected to the impact block, the other side wall of the impact plate is fixedly installed with an impact fixing rod, the inside of the impact plate is rollingly connected to the impact sliding rod, the end of the impact fixing rod is fixedly installed with an impact ring, the side wall of the impact plate is fixedly installed with an impact spring, the side wall of the impact spring is fixedly installed with a rebound plate, and the rebound plate is rollingly installed on the outer wall of the second transmission rod.

First, the cleaning column is adjusted and rotated to a length suitable for entering the inside of the rotating plate into the bearing, and then the cleaning column is rotated to the inside of the bearing disassembly support frame. The rotation of the rotating plate drives the cleaning column and the cleaning spring to rotate, and the rotation of the cleaning spring drives the cleaning plate and the brush to rotate, and the brush rotates on the inner wall of the bearing frame to brush and clean the inner wall of the bearing frame.

[0014] Preferably, the outer wall of the worm gear is rollingly connected to a power limiting ring, the top of the power limiting ring is fixedly connected to a power spring, and the top of the power spring is fixedly connected to the inside of the clamping moving block. When the worm gear rotates, the power spring on the outer wall of the power limiting ring bounces the worm gear to the lower end, so that the worm gear can be engaged with the teeth. When the clamping moving block needs to be moved, the worm gear can be pulled, and the worm gear can be disengaged from the teeth when pulled, thereby facilitating the clamping moving block to be adjusted to a suitable position to clamp the bearing.

[0015] Preferably, a limit fixing block is fixedly installed on the side wall of the base support frame, and a threaded limit column is connected to the inside of the limit fixing block in a rolling manner. The side wall of the threaded limit column is fixedly connected to a second handle, and a limit circular hole is provided on the side wall of the adjusting rotating column. The limit circular hole and the threaded limit column engage with each other. When the threaded limit column is rotated, the threaded limit column engages with the limit circular hole on the surface of the adjusting rotating column, which can play the effect of fixing the limit circular hole. After removing the bearing, when the bearing needs to be rotated for repositioning, the second handle can be held again to rotate the threaded limit column. The threaded limit column rotates and engages with the limit circular hole, thereby facilitating the rotation of the adjusting rotating column.

[0016] Preferably, the end of the first transmission rod passes through the end of the adjusting rotating column close to the base support frame side, and the outer wall of the end of the first transmission rod is fixedly connected to a rotating handle. The rotating handle at the end of the first transmission rod can facilitate the rotation of the first transmission rod. When the first transmission rod needs to be adjusted and rotated, the rotating handle can be held to rotate the first transmission rod, and the rotation of the first transmission rod can drive the whole to move and adjust.

[0017] Preferably, the first transmission rod is rollingly connected to the center upper end of the adjusting rotating column, and the teeth are located at the center lower end of the adjusting rotating column. The first transmission rod is located at the center upper end of the adjusting rotating column to prevent the first transmission rod from touching the teeth when rotating, and the lock adjusting column is located at the center position of the adjusting rotating column when rotating. The teeth are lower than the center position to prevent the lock adjusting column from squeezing the teeth, thereby providing protection for the device.

[0018] Preferably, the clamping moving block and the second transmission rod always remain concentric with the adjusting rotating column. The clamping moving block and the adjusting rotating column remain concentric, and the clamping moving block can be conveniently moved after the clamping moving block clamps the bearing, so that the clamping moving block moves along the outer wall of the adjusting rotating column, and the second transmission rod remains concentric with the adjusting rotating column, so that the device on the outer wall of the second transmission rod can slide on the outer wall of the adjusting rotating column.

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0039] Example 1 Figure 1-3 As shown, a rolling mill shaft disassembly and assembly device according to an embodiment of the present invention includes an adjusting rotary column 12 that is rollingly mounted on a base support frame 1, a plurality of teeth 123 are provided inside the adjusting rotary column 12, and a moving component 2 is rollingly connected to the outer wall of the adjusting rotary column 12. The moving component 2 includes:

[0040] A limit slider 23 is slidably connected to the outer wall of the adjusting rotating column 12. A plurality of support columns 22 are installed on the outer wall of the limit slider 23. A limit ring 21 is fixedly installed on the outer wall of the support column 22.

[0041] The clamping moving block 25 is slidably installed on the outer wall of the adjusting rotating column 12, and the clamping moving block 25 is installed near the end of the adjusting rotating column 12. A rotating gear block 26 is rollingly installed inside the clamping moving block 25. A spiral pattern 261 is fixedly installed on one side wall of the rotating gear block 26, and an annular rack 262 is fixedly installed on the other side of the rotating gear block 26. A telescopic arm 27 is slidably installed on the side wall of the clamping moving block 25. A groove is provided on the side wall of the telescopic arm 27 to engage with the spiral pattern 261 for transmission. The interior of the clamping moving block 25 is rollingly connected to the second transmission rod 51, and the end of the second transmission rod 51 is fixedly connected to two second rotating blocks 511. The inner wall of the second rotating block 511 is fixedly connected to the second rotating cylinder 512, and the outer wall of the second rotating cylinder 512 is rollingly connected to the worm gear 53.

[0042] Specifically, the internal rolling connection of the clamping moving block 25 is provided with a movable adjustment bevel gear 57, and the top of the movable adjustment bevel gear 57 is fixedly connected with a movable adjustment round gear 571, and the outer wall of the movable adjustment round gear 571 is meshed with the annular rack 262. The rolling mill bearing is installed on the support frame of the rolling mill. Before disassembling the rolling mill bearing, the bearing is preliminarily moved so that a part of the inner wall of the bearing is separated from the support frame; first adjust the position of the base support frame 1, place the limiting ring 21 on the outside of the rolling mill, and then move the clamping moving block 25 into the rolling mill bearing to be disassembled, and start preparing to disassemble the bearing, rotate the annular rack 262 on the side wall of the rotating gear circle block 26, and the annular rack 262 rotates. The rotation of the annular rack 262 drives the spiral pattern 261 to rotate, and the spiral pattern 261 is meshed with the thread on the surface of the telescopic arm 27, thereby extending multiple telescopic arms 27 outward with the rotating gear circle block 26 as the center of the circle, and multiple telescopic arms 27 simultaneously press against The worm gear 53 is engaged with the teeth 123, thereby driving the second transmission rod 51 to move along the adjusting rotating column 12 toward the side of the base support frame 1, thereby pulling the bearing out of the support frame, and completing the disassembly of the bearing. The bearing remains stable during the pulling-out process, which improves the problem that when the bearing is directly pushed out of the support frame, there is no support inside, and the bearing is easy to roll around after being pushed away, which may pose a safety hazard; when installing the bearing, the same reverse operation can be performed. This device can adjust the position of the clamping moving block 25 by rotating the worm gear 53. At the same time, when clamping the bearing, the position of the telescopic arm 27 can also be extended by rotating the worm gear 53. The extension length of the telescopic arm 27 is adjustable, and bearings of different sizes can be replaced. During use, multiple telescopic arms 27 can fix the position of the column bearing to complete the disassembly of the bearing.

[0043] like Figure 2-3 As shown, the outer wall of the limit sliding block 23 is slidably connected to the support sliding column 242, the outer wall of the support sliding column 242 is fixedly connected to the spring support block 241, the support sliding column 242 passes through the limit ring 21 and is movably connected to the inside of the limit ring 21, and the outer wall of the support sliding column 242 is provided with a limit spring 24, which is located on the inner wall of the spring support block 241 and the limit ring 21.

[0044] Specifically, when the limiting ring 21 needs to be limited and fixed, it is necessary to hold the support sliding column 242 and slide the support sliding column 242 outward until the support sliding column 242 is moved out of the interior of the support column 22. The extension length of the support sliding column 242 and the position of engagement with the teeth 123 can be adjusted. When adjusted to the appropriate position, the support sliding column 242 can be released. The support sliding column 242 moves inward under the drive of the limiting spring 24, thereby engaging with the teeth 123 and completing the engagement of the adjusting rotating column 12. This device can effectively adjust the angle of engagement with the bearing support on the outer wall of the bearing ring, thereby facilitating the disassembly of the bearing.

[0045] like Figure 7-8 As shown, the interior of the adjusting rotating column 12 is rollingly connected with a transmission structure 5, and the transmission structure 5 includes a first transmission rod 56 rollingly connected to the interior of the adjusting rotating column 12, and a locking cylinder 55 is fixedly installed on the end of the first transmission rod 56, and the end of the worm gear 53 of the locking cylinder 55 is fixedly connected with the worm gear 53, and the worm gear 53 and the first transmission rod 56 are rotationally connected through the locking adjusting column 54.

[0046] Specifically, when the first transmission rod 56 is rotated, the first transmission rod 56 and the lock cylinder 55 drive the lock adjustment column 54 to rotate, and the rotation of the lock adjustment column 54 drives the worm gear 53 to rotate. The rotation of the worm gear 53 drives the movable adjustment helical teeth 57 to engage with the helical teeth on the outer wall of the second transmission rod 51, completing the engagement and rotation of the movable adjustment circular teeth 571. The rotation of the movable adjustment circular teeth 571 drives the annular rack 262 on the side wall of the rotating gear circle block 26 to engage, thereby driving the rotating gear circle block 26 to rotate. This device facilitates the clamping and movement of the bearing.

[0047] like Figure 4-5 As shown, the outer wall end of the second transmission rod 51 is rollingly connected with the impact device 3, and the impact device 3 includes a rotating plate 31 fixedly connected to the outer wall of the second transmission rod 51, and the side wall of the rotating plate 31 is fixedly connected with a triangular block 311, and the outer wall of the second transmission rod 51 is slidingly connected with the impact plate 32, and one side wall of the impact plate 32 is fixedly connected with an impact block 321, and the other side wall of the impact plate 32 is fixedly installed with an impact fixing rod 323, and the inside of the impact plate 32 is rollingly connected with an impact sliding rod 322, and the end of the impact fixing rod 323 is fixedly installed with an impact ring 34, and the side wall of the impact plate 32 is fixedly installed with an impact spring 324, and the side wall of the impact spring 324 is fixedly installed with a rebound plate 33, and the rebound plate 33 is rollingly installed on the outer wall of the second transmission rod 51.

[0048] When the second transmission rod 51 rotates, the rotating plate 31 is fixedly connected to the second transmission rod 51, thereby driving the rotating plate 31 to rotate, and the rotation of the rotating plate 31 drives the triangular block 311 to rotate on the outer wall of the rotating plate 31, and the impact plate 32 is slidably connected to the outer wall of the second transmission rod 51, and the rotating plate 31 drives the triangular block 311 to collide with the impact block 321 on the side wall of the impact plate 32, thereby driving the impact plate 32 to move inward, and when the impact plate 32 moves inward, it drives the impact fixing rod 323 and the impact ring 34 on the side wall to collide with the clamping moving block 25, knocking and impacting when the bearing is disassembled, and the rebound plate 33 on the outer wall of the second transmission rod 51 engages with the impact spring 324, and the impact spring 324 is fixedly connected to the side wall of the impact plate 32. After the impact plate 32 moves inward, the elastic force of the impact spring 324 will pop the impact plate 32 outward, so that the impact plate 32 continues to hit the clamping moving block 25 under the action of the triangular block 311, thereby facilitating the disassembly of the bearing.

[0049] like Figure 4 As shown, a cleaning device 4 is slidably installed on the outer wall of the rotating plate 31. The cleaning device 4 includes a plurality of cleaning columns 41 slidably installed on the outer wall of the rotating plate 31. A cleaning spring 42 is slidably installed inside the cleaning column 41. A cleaning plate 43 is fixedly installed on the end of the cleaning spring 42. A plurality of brushes 44 are fixedly installed on the top of the cleaning plate 43.

[0050] Specifically, first adjust the cleaning column 41 and rotate the cleaning column 41 to a length suitable for entering the bearing inside the rotating plate 31. Then rotate the cleaning column 41 to the inside of the bearing disassembly support frame. The rotation of the rotating plate 31 drives the cleaning column 41 and the cleaning spring 42 to rotate, and the rotation of the cleaning spring 42 drives the cleaning plate 43 and the brush 44 to rotate. The brush 44 rotates on the inner wall of the bearing frame to brush and clean the inner wall of the bearing frame.

[0051] like Figure 8 As shown, the outer wall of the worm gear 53 is rollingly connected to a power limiting ring 52 , the top of the power limiting ring 52 is fixedly connected to a power spring 521 , and the top of the power spring 521 is fixedly connected to the inside of the clamping moving block 25 .

[0052] Specifically, when the worm gear 53 rotates, the power spring 521 on the outer wall of the power limiting ring 52 bounces the worm gear 53 toward the lower end, so that the worm gear 53 can be engaged with the teeth 123. When the clamping moving block 25 needs to be moved, the worm gear 53 can be pulled. When the worm gear 53 is pulled, it can be disengaged from the teeth 123, thereby facilitating the clamping moving block 25 to be adjusted to a suitable position to clamp the bearing.

[0053] like Figure 6As shown, a limiting fixing block 14 is fixedly installed on the side wall of the base support frame 1, and a threaded limiting column 15 is rollingly connected inside the limiting fixing block 14. The side wall of the threaded limiting column 15 is fixedly connected to a second handle 16, and a limiting circular hole 122 is provided on the side wall of the adjusting rotating column 12, and the limiting circular hole 122 is engaged with the threaded limiting column 15.

[0054] Specifically, when the threaded limit column 15 is rotated, the threaded limit column 15 engages with the limit circular hole 122 on the surface of the adjustment rotation column 12, which can fix the limit circular hole 122. After the bearing is removed, when the bearing needs to be rotated, the second handle 16 can be held again to rotate the threaded limit column 15. The threaded limit column 15 rotates and engages with the limit circular hole 122, so that the adjustment rotation column 12 can be easily rotated.

[0055] like Figure 8 As shown, the end of the first transmission rod 56 passes through the end of the adjustment rotation column 12 close to the base support frame 1 side, and the outer wall of the end of the first transmission rod 56 is fixedly connected to the rotating handle 561.

[0056] Specifically, the rotating handle 561 at the end of the first transmission rod 56 can facilitate the rotation of the first transmission rod 56. When the first transmission rod 56 needs to be adjusted and rotated, the rotating handle 561 can be held to rotate the first transmission rod 56, and the rotation of the first transmission rod 56 can drive the entire body to move and adjust.

[0057] like Figure 6 As shown, the first transmission rod 56 is rollingly connected to the central upper end of the adjustment rotating column 12 , and the teeth 123 are located at the central lower end of the adjustment rotating column 12 .

[0058] Specifically, the first transmission rod 56 is located at the center upper end of the adjusting rotating column 12 to prevent the first transmission rod 56 from touching the teeth 123 when rotating, and the lock adjustment column 54 is located at the center position of the adjusting rotating column 12 when rotating, and the teeth 123 are lower than the center position to prevent the lock adjustment column 54 from squeezing the teeth 123, thereby protecting the device.

[0059] like Figure 1-8 As shown, the clamping moving block 25 and the second transmission rod 51 always remain concentric with the adjustment rotating column 12.

[0060] Specifically, the clamping moving block 25 and the adjusting rotating column 12 remain concentric, and the clamping moving block 25 can be conveniently moved after the clamping moving block 25 clamps the bearing, so that the clamping moving block 25 moves along the outer wall of the adjusting rotating column 12, and the second transmission rod 51 remains concentric with the adjusting rotating column 12, so that the device on the outer wall of the second transmission rod 51 can slide on the outer wall of the adjusting rotating column 12.

[0061] Working principle: Before disassembling the bearing, first adjust the limit position of the threaded limit column 15 and the limit hole 122, rotate the second handle 16, thereby driving the threaded limit column 15 to rotate, and the limit hole 122 engages with the threaded limit column 15, thereby completing the limit of the adjustment rotation column 12, and then pull the support sliding column 242 outward to disengage the support sliding column 242 from the position of the tooth 123. After adjusting to the appropriate distance, the support sliding column 242 is engaged with the tooth 123. At this time, the entire part of the clamping moving block 25 is located at the edge of the adjustment rotation column 12, and hold the rotating handle. 561 pulls the first transmission rod 56, and the first transmission rod 56 drives the lock adjustment column 54 to pull the worm gear 53 upward, so that the worm gear 53 is out of engagement with the tooth 123, thereby driving the clamping moving block 25 to adjust the position. When it is adjusted to the position where the bearing seat can clamp the bearing, the bearing can be disassembled. The first transmission rod 56 is rotated, and the first transmission rod 56 drives the worm gear 53 to rotate, and the rotation of the worm gear 53 drives the second transmission rod 51 to rotate. The rotation of the second transmission rod 51 drives the movement adjustment helical gear 57 and the movement adjustment round gear 571 to rotate, and the movement adjustment The circular teeth 571 are adjusted to mesh with the annular rack 262, thereby driving the rotating gear circle block 26 to rotate. The rotation of the rotating gear circle block 26 drives the telescopic arm 27 to move outward. When the telescopic arm 27 moves to the same size as the outer diameter of the bearing, the clamping of the bearing is completed. Then, the first transmission rod 56 is released, so that the worm gear 53 drives the worm gear 53 to mesh with the teeth 123 under the action of the power spring 521, thereby driving the worm gear 53 to move toward the side of the base support frame 1 when the first transmission rod 56 is rotated, and the rotating plate 31 on the outer wall of the second transmission rod 51 drives the triangular block 311 to impact the plate 32 moves in and out, and the impact plate 32 drives the impact fixing rod 323 and the impact ring 34 to impact the clamping moving block 25. A rebound plate 33 is provided on the surface of the second transmission rod 51. The impact spring 324 on the side wall of the rebound plate 33 drives the impact plate 32 to pop out outward, so that when the second transmission rod 51 rotates and drives the rotating plate 31 to rotate, it continuously impacts the impact plate 32. When the bearing is pulled out of the bearing seat, the disassembly of the bearing is completed. When the force angle of the bearing needs to be adjusted, the threaded limit column 15 is loosened to separate the limiting circular hole 122 from the threaded limit column 15. Hold the first handle 121 to rotate the adjusting rotating column 12. After rotating the adjusting rotating column 12 180°, hold the second handle 16 again to rotate the threaded limiting column 15. Fix the threaded limiting column 15 to the limiting hole 122 to complete the fixation of the adjusting rotating column 12, and then complete the disassembly and angle replacement of the bearing. This device does not require manual adjustment of the bearing disassembly device, and during use, multiple telescopic arms 27 can easily fix the bearing, completing the clamping of the bearing. Bearings with different diameters can be disassembled, so that the force is more uniform during the clamping process of the bearing.
