Description

Technical Field

[0001] The present invention relates to the technical field of roller feeding for slewing bearings, and specifically to a roller feeding device for slewing bearing assembly. Background Art

[0002] Slewing bearings are widely used. Construction machinery is the place where slewing bearings were first applied and are most widely used, such as earthmoving machinery, excavators, demolition machines, stacker reclaimers, graders, rollers, dynamic compaction machines, rock drilling machinery, tunneling machines, etc. A slewing bearing is a new type of mechanical component, which consists of an outer ring, an inner ring, rolling elements, etc. A slewing bearing is a large bearing that can withstand combined loads and can simultaneously withstand large axial, radial loads and overturning moments.

[0003] Since most of the rollers are located inside the outer track and the inner track, the positioning accuracy of the rollers will be greatly affected during feeding. At the same time, after a single operation is completed, whether the automated feeding process of the rollers and the collision between a large number of stored rollers will affect the lubrication degree between the rollers and the outer track and the inner track. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the technical solution adopted by the present invention to solve its technical problems is as follows: A roller feeding device for slewing bearing assembly according to the present invention includes a rotating component, the top of the rotating component is fixedly connected with a fixing component, the inner cavity of the fixing component is fixedly connected with a lifting component, the top of the inner cavity of the rotating component is rotatably connected with a feeding component, the bottom of the inner cavity of the rotating component is slidably connected with a folding storage component. The rollers enter the folding storage component through the rotating component, and then enter the feeding component under the action of multiple folding ball storage devices and roller platforms in the folding storage component. The feeding component rotates, so that the rollers enter the outer track under the action of centrifugal force. The lifting component adjusts the position of the rollers between the outer track and the inner track. After the feeding work is completed, the fixing component moves, so that a slewing bearing assembly component migrates and starts to fix the outer track of the next slewing bearing assembly. The rotating component includes a roller box. At the top of the inner cavity of the rotating component, there is a roller storage chamber fixedly connected. At the bottom of the inner cavity of the rotating component, there is a rotating chamber fixedly connected. At the top of the roller box, there is a tipping control ring fixedly connected. At the axis center of the inner cavity of the roller storage chamber, there is a roller guide port fixedly connected. A rotating shaft is slidably connected to the outer surface of the roller guide port. An inlet valve is rotatably connected to the top of the roller guide port. A storage is fixedly connected to the top of the inlet valve. A transition plate is fixedly connected to the top of the storage. The rollers in the roller storage chamber are surface-cleaned through the rotating chamber and enter the storage through the inlet valve under the action of the roller guide port. The rotating shaft works to drive the roller guide port and the inlet valve to rotate, and then makes the storage rotate. Since the bottom of the storage is semi-circular and under the control of the tipping control ring, the storage and the transition plate rotate in a circular motion around the roller guide port, causing the rollers to enter the track due to the inclination of the storage rotation and their own gravity.

[0005] Preferably, the bottom of the lifting component is fixedly connected to the top of the rotating component. The bottom of the feeding component is slidably connected to the top of the folding storage component. The number of the fixing components is two, the number of the lifting components is four, the outer surface of the rotating shaft is slidably connected to the inner cavity of the roller storage chamber. The top of the rotating chamber is fixedly connected to the bottom of the roller storage chamber. The inner cavity of the tipping control ring is rotatably connected to the outer surface of the storage. By setting the rotating component and designing the storage to have a hemispherical bottom, it can be used to make a circular rotation motion during feeding positioning, enabling the flat rollers to automatically enter the outer track and the inner and outer transition rings as the storage rotates, further facilitating the fixing of the rollers. At the same time, the rotation angle of the storage is controllable, thus improving the positioning efficiency of the rollers.

[0006] Preferably, the feeding component includes a ball rack, a ball hole is fixedly connected to the inner cavity of the ball rack, a centrifugal motor is rotatably connected to the bottom of the ball rack, a rotating column is fixedly connected to the outer surface of the centrifugal motor, a support disc is fixedly connected to the outer surface of the rotating column, a centrifugal plate is slidably connected to the inner cavity of the support disc, a centrifugal spring is slidably connected to one side of the centrifugal plate close to the rotating column, a connecting column is slidably connected to one end of the centrifugal spring close to the rotating column, ball holes are uniformly arranged in the inner cavity of the ball rack, one end of the connecting column close to the rotating column is fixedly connected to the inner wall of the support disc, the bottom of the ball rack is rotatably connected to the top of the support disc, the number of the centrifugal plates is six, and the number of the connecting columns is twelve. The rollers entering the roller table move in the reverse direction and then enter the ball holes in the ball rack. To make the rollers move upward, the centrifugal motor drives the rotating column to rotate, and at the same time drives the support disc to rotate. Since the centrifugal plate is connected to the centrifugal spring, under the action of centrifugal force and elastic force, the centrifugal plate moves outward. When the rotation stops, under the action of the centrifugal spring, the centrifugal plate contracts inward into the support disc. By providing the feeding component, the rotation of the support disc drives the centrifugal plate. Under the action of centrifugal force and elastic force, the centrifugal plate moves outward. When the rotation stops, under the action of the centrifugal spring, the centrifugal plate contracts inward into the support disc. Through the centrifugal motor and the centrifugal spring in the rotating column, the whole process from the roller being picked up to entering between the outer track and the inner track is realized.

[0007] Preferably, the folding storage component includes a roller table. The outer surface of the roller table is fixedly connected with a table periphery. The inner cavity of the roller table is fixedly connected with an inner table periphery. The outer surface of the inner table periphery is fixedly connected with an inner periphery track. The inner cavity of the inner table periphery is fixedly connected with a lifting motor. The bottom of the table periphery is fixedly connected with a top-layer ball storage device. One end of the outer surface of the top-layer ball storage device close to the table periphery is fixedly connected with a table track. The bottom of the table track is fixedly connected with an upper clamping block. The bottom of the upper clamping block is slidably connected with a clamping block spring. The bottom of the top-layer ball storage device is slidably connected with a second ball storage device. One end of the outer surface of the second ball storage device close to the top-layer ball storage device is fixedly connected with a first lower clamping block. The bottom of the second ball storage device is slidably connected with a third ball storage device. One end of the outer surface of the third ball storage device close to the second ball storage device is fixedly connected with a second lower clamping block. The bottom of the third ball storage device is slidably connected with a bottom-layer ball storage device. One end of the outer surface of the bottom-layer ball storage device close to the third ball storage device is fixedly connected with a third lower clamping block. The top of the bottom-layer ball storage device is fixedly connected with a support plate. The rollers entering the folding storage component through the inlet valve are stored in multiple ball storage devices. When starting to assemble and obtain the rollers, the inner table periphery moves down along the track to the highest surface of the roller table under the action of the inner periphery track. The roller table then moves down along the track of the table track, causing the clamping block spring to move down under the action of the upper clamping block, and further causing the top-layer ball storage device to move down. Due to the height difference, the rollers in the top-layer ball storage device enter the roller table. The shielding of the table periphery prevents the rollers from falling. When the rollers in the top-layer ball storage device are processed, the upper clamping block will be clamped with the first lower clamping block, and the top-layer ball storage device and the second ball storage device are in a folded state and move down together to process the rollers in the second ball storage device. The movement process of the third ball storage device and the bottom-layer ball storage device is the same as that of the top-layer ball storage device and the second ball storage device. By setting the folding storage component and multiple ball storage devices, the storage capacity of the rollers is increased. At the same time, in a folded manner, using the connection between the upper clamping block and multiple lower clamping blocks, it is convenient to move the stored rollers upward, realizing the one-time assembly and one-time picking method of the rollers, and improving the picking efficiency of the rollers.

[0008] Preferably, the fixing component includes a horizontal telescopic rod. A second track fixer is slidably connected to one side of the horizontal telescopic rod close to the transition plate. A first track fixer is slidably connected to the inner cavity of the second track fixer. An upper spring is fixedly connected to the inner cavity of the first track fixer. The top of the upper spring is fixedly connected to a fixer lifting valve. The bottom of the upper spring is fixedly connected to a lower spring. A fixing rod is slidably connected to one side of the horizontal telescopic rod away from the second track fixer. A steering wheel is rotatably connected to one side of the fixing rod away from the horizontal telescopic rod. When the entire assembly of the slewing bearing is completed and the outer track of the next component needs to be replaced, after the fixing of one component is completed, the fixing component starts to move to release the fixing between the component and the fixing component. The fixing is released by the horizontal telescopic movement of the horizontal telescopic rod and the rotation direction of the fixing rod. For the fixing of the next component, the outer track is fixed by the first track fixer, and the fixer lifting valve and the lower spring are adjusted by the upper spring, thereby adjusting the position of the first track fixer so that the first track fixer is combined and fixed with the outer track. The fixing component is provided to facilitate the fixing of the outer track of the next component after one slewing bearing assembly is completed, improve the assembly efficiency, and realize the automation process of the assembly.

[0009] Preferably, the lifting component includes an outer track. An inner-outer transition ring is slidably connected to the inner wall of the outer track. An inner track is slidably connected to one side of the inner-outer transition ring away from the outer track. An outer track lifting valve is fixedly connected to the bottom of the outer track.

The bottom of the inner track lifting valve is fixedly connected to an inner track rod. A second vertical telescopic rod is slidably connected to the outer surface of the inner track rod. The feeding component enables the rollers to move outward under the action of centrifugal force. The outer track rises under the action of the first vertical telescopic rod and slides relative to the inner-outer transition ring at the same time, so that the moving rollers enter between the outer track and the inner-outer transition ring to fix the positions of the rollers. Then the inner track moves upward under the action of the second vertical telescopic rod. The outer track rod and the inner track rod are connected by the coupling platform and restrict each other while interacting, so that the entire assembly of the slewing bearing is completed. By providing the lifting component, the rollers are assembled in the order of outer track - roller positioner - roller - inner track, improving the positioning accuracy of the rollers.

[0010] Preferably, an inner rail rod is fixedly connected to the side of the coupling platform away from the outer rail rod. The number of coupling platforms is four, the number of inner and outer transition rings is two, the number of inner peripheral tracks is two, the outer surface of the support plate is fixedly connected to the inner cavity of the storage device. The roller enters the top ball storage device, the second ball storage device, the third ball storage device, and the bottom ball storage device of the folding storage component through the rotating component. At the same time, the roller is obtained and enters the roller table through the clamping connection between the upper clamping block and the first lower clamping block, the second lower clamping block, and the third lower clamping block. At the same time, under the rotation of the rotating column of the feeding component, the roller moves upward under the action of centrifugal force and the extrusion of the centrifugal plate into the outer track and is fixed by the inner and outer transition rings. The first vertical telescopic rod and the second vertical telescopic rod in the lifting component make the outer track, inner track, inner and outer transition rings, and the roller assembled completely. After the feeding work is completed, the fixing component moves to make a slewing bearing assembly component migrate and start to fix the outer track of the next slewing bearing assembly.

[0011] The beneficial effects of the present invention are as follows: (1) By setting the rotating component in the present invention, the storage device is designed to have a hemispherical bottom shape, so that during the feeding positioning, its circular rotation movement can be utilized, and the flat rollers can automatically enter the outer track and the inner and outer transition rings as the storage device rotates, which further facilitates the fixing of the rollers. At the same time, the rotation angle of the storage device is controllable, so the positioning efficiency of the rollers is improved and the possibility of lubrication effect reduction caused by roller damage is reduced.

[0012] (2) By setting the feeding component in the present invention, the rotation of the support disc drives the centrifugal plate. Under the action of centrifugal force and elastic force, the centrifugal plate moves outward. When the rotation stops, the centrifugal plate contracts inward into the support disc under the action of the centrifugal spring. Through the centrifugal motor and centrifugal spring in the rotating column, the whole process from the roller being picked up to entering the outer track and the inner track is realized.

[0013] (3) By setting the folding storage component in the present invention, multiple ball storage devices are set to increase the storage capacity of the rollers. At the same time, in a folded manner, through the connection between the upper clamping block and multiple lower clamping blocks, it is convenient to move the stored rollers upward, realizing the one-time assembly and one-time picking method of the rollers, and improving the picking efficiency of the rollers.

The embodiments of the present invention are given for purposes of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better explain the principles of the invention and its practical application, and to enable those of ordinary skill in the art to understand the invention and design various embodiments with various modifications suitable for specific purposes.

[0017] Example 1: Use Figures 1-3A roller feeding device for assembling a slewing bearing according to an embodiment of the present invention will be described as follows.

[0018] As Figures 1-3 shown, a roller feeding device for assembling a slewing bearing according to the present invention includes a rotating member 1. A fixing member 2 is fixedly connected to the top of the rotating member 1. A lifting member 3 is fixedly connected to the inner cavity of the fixing member 2. A feeding member 4 is rotatably connected to the top of the inner cavity of the rotating member 1. A folding storage member 5 is slidably connected to the bottom of the inner cavity of the rotating member 1. The rollers enter the folding storage member 5 through the rotating member 1, and then enter the feeding member 4 under the action of a plurality of folding ball storage devices and a roller table 501 in the folding storage member 5. The feeding member 4 rotates, so that the rollers enter the outer track 301 under the action of centrifugal force. The lifting member 3 adjusts the position of the rollers between the outer track 301 and the inner track 303. After the feeding work is completed, the fixing member 2 moves, so that a slewing bearing assembly component migrates and starts to fix the outer track 301 of the next slewing bearing assembly; The rotating member 1 includes a roller box 11. A roller storage chamber 16 is fixedly connected to the top of the inner cavity of the rotating member 1. A rotating chamber 15 is fixedly connected to the bottom of the inner cavity of the rotating member 1. A dumping control ring 12 is fixedly connected to the top of the roller box 11. A roller guide port 19 is fixedly connected to the center of the inner cavity of the roller storage chamber 16. A rotating shaft 18 is slidably connected to the outer surface of the roller guide port 19. An inlet valve 17 is rotatably connected to the top of the roller guide port 19. A storage device 13 is fixedly connected to the top of the inlet valve 17. A transition plate 14 is fixedly connected to the top of the storage device 13.

[0019] The bottom of the lifting member 3 is fixedly connected to the top of the rotating member 1. The bottom of the feeding member 4 is slidably connected to the top of the folding storage member 5. The number of the fixing members 2 is two. The number of the lifting members 3 is four. The outer surface of the rotating shaft 18 is slidably connected to the inner cavity of the roller storage chamber 16. The top of the rotating chamber 15 is fixedly connected to the bottom of the roller storage chamber 16. The inner cavity of the dumping control ring 12 is rotatably connected to the outer surface of the storage device 13.

The rotating shaft 18 works to drive the roller guide port 19 and the inlet valve 17 to rotate, and then makes the storage device 13 rotate. Since the bottom of the storage device 13 is semicircular, and under the control of the dumping control ring 12, the storage device 13 and the transition plate 14 rotate in a circular motion around the roller guide port 19, so that the rollers enter the track due to the inclined condition of the rotation of the storage device 13 and their own gravity.

[0021] Embodiment 2, use Figures 1-7The following describes a roller feeding device for assembling a slewing bearing according to an embodiment of the present invention.

[0022] As Figures 1-7 shown, in the roller feeding device for assembling a slewing bearing according to the present invention, on the basis of the first embodiment, the feeding component 4 includes a ball rack 41.

A centrifugal spring 46 is slidably connected to one side of the centrifugal plate 48 close to the rotating column 44. A connecting column 45 is slidably connected to one end of the centrifugal spring 46 close to the rotating column 44.

[0023] The ball holes 42 are uniformly arranged in the inner cavity of the ball rack 41. One end of the connecting column 45 close to the rotating column 44 is fixedly connected to the inner wall of the support disc 47. The bottom of the ball rack 41 is rotatably connected to the top of the support disc 47. The number of the centrifugal plates 48 is six, and the number of the connecting columns 45 is twelve. The rollers entering the roller table 501 move in the reverse direction and then enter the ball holes 42 in the ball rack 41. To make the rollers move upward, the centrifugal motor 43 drives the rotating column 44 to rotate, and at the same time drives the support disc 47 to rotate. Since the centrifugal plate 48 is connected to the centrifugal spring 46, under the action of centrifugal force and elastic force, the centrifugal plate 48 moves outward. When the rotation stops, under the action of the centrifugal spring 46, the centrifugal plate 48 contracts inward into the support disc 47.

[0024] The folding storage component 5 includes a roller table 501. The outer surface of the roller table 501 is fixedly connected with a table periphery 502.

The top of the bottom ball storage 516 is fixedly connected with a support plate 512. The rollers entering the folding storage component 5 through the inlet valve 17 are stored in multiple ball storages. When starting to assemble and obtain the rollers, the table inner periphery 503 moves down along the track to the highest surface of the roller table 501 under the action of the inner periphery track 504. Then the roller table 501 moves down along the track of the table track 506, so that the clamping block spring 508 moves down under the action of the upper clamping block 507, and then the top ball storage 513 moves down. Due to the height difference, the rollers in the top ball storage 513 enter the roller table 501. The shielding of the table periphery 502 prevents the rollers from falling. When the rollers in the top ball storage 513 are processed, the upper clamping block 507 will be clamped with the first lower clamping block 509, and the top ball storage 513 and the second ball storage 514 are in a folded state and move down together to process the rollers in the second ball storage 514.

When the entire assembly of the slewing bearing is completed, the outer track 301 of the next component needs to be replaced. After the fixation of one component is completed, the fixed component 2 starts to move to release the fixation between the component and the fixed component 2. The release of the fixation is achieved through the horizontal expansion and contraction of the horizontal telescopic rod 21 and the rotation direction of the fixed rod 22. When starting to fix the next component, the outer track 301 is fixed by the first track fixator 24. The fixator lifting valve 26 and the lower spring 28 are adjusted through the upper spring 27, and then the position of the first track fixator 24 is adjusted so that the first track fixator 24 is combined and fixed with the outer track 301.

The feeding component 4 causes the rollers to move outward under the action of centrifugal force. The outer track 301 rises under the action of the first vertical telescopic rod 305 and simultaneously slides relative to the inner-outer transition ring 302, so that the moving rollers enter between the outer track 301 and the inner-outer transition ring 302 to fix the positions of the rollers. Then the inner track 303 moves upward under the action of the second vertical telescopic rod 309. The outer track rod 306 and the inner track rod 308 are connected by the coupling platform 307. While interacting with each other, they also restrict each other, completing the entire assembly of the slewing bearing.

At the same time, under the rotation of the rotating column 44 of the feeding component 4, the roller moves upward under the action of centrifugal force and the extrusion of the centrifugal plate 48 and enters the outer track 301 and is fixed by the inner and outer transition rings 302. The first vertical telescopic rod 305 and the second vertical telescopic rod 309 in the lifting component 3 make the outer track 301, the inner track 303, the inner and outer transition rings 302, and the roller assembled completely. After the feeding work is completed, the fixing component 2 moves so that a slewing bearing assembly component migrates and starts to fix the outer track 301 of the next slewing bearing assembly.
