Description

Technical Field

[0001] The present application relates to the technical field of bearing assembly equipment, and in particular to a roller bearing assembly mechanism. Background Art

[0002] Rolling bearings are precision mechanical components that convert the sliding friction between the rotating shaft and the shaft seat into rolling friction, thereby reducing friction losses. They consist of an inner ring, an outer ring, rollers, and a cage; the inner ring and the outer ring are two cylinders, and the rollers are cylindrical rolling elements. The cage maintains a certain gap between the rollers and the inner and outer rings to allow the rollers to roll freely, and when assembling roller bearings, they usually need to be used with assembly tools.

[0003] For example, the Chinese patent document with the announcement number CN108006088B discloses a roller bearing assembly device, including the above-mentioned blanking device, a feeding assembly for receiving the roller dropped by the blanking device, a roller assembly assembly for assembling the roller into the cage, and a SCARA manipulator for grabbing the roller dropped into the feeding assembly to the roller assembly assembly. When it is necessary to install the conical roller into the cage, first, place the cage on the workbench and place it around the mounting hole with the small end opening facing downward and the large end opening facing upward, and use the blanking device to automatically and orderly transport the rollers to the feeding assembly; then, place the rollers on the feeding assembly one by one into the above-mentioned accommodating cavities, and finally complete the assembly of the rollers in the cage.

[0004] In the above-mentioned related technologies, after the cage is placed, the position of the cage needs to be adjusted manually multiple times so that the mounting groove and the limit groove on the cage correspond to each other. At the same time, the cage and the limit plate need to be coaxially arranged. The roller can be placed only after the cage adjustment is completed, which causes a decrease in the assembly efficiency of the roller bearing. Summary of the invention

[0009] By adopting the above technical solution, the limit rod can drive the three limit plates to move simultaneously during the movement in the vertical direction, and finally the position of the retaining frame can be adjusted by the limit plate, and finally the retaining frame and the limit plate are coaxially arranged, so that the roller can be installed in the installation groove and the limit groove.

[0010] Optionally, an electromagnet is provided on the movable plate, and an end of the calibration plate away from the limiting plate is made of iron material.

[0011] By adopting the above technical solution, after the retaining frame pushes the proofreading plate out of the mounting groove, the electromagnet is energized, at which time the proofreading plate is fixed on the movable plate, and the proofreading spring is compressed. When the control component drives the movable plate to move away from the limit disk, the electromagnet is de-energized, and at this time, the proofreading plate is pushed toward the limit disk under the action of the proofreading spring. Finally, it is convenient to adjust the position of the subsequent retaining frame so that the mounting groove on the subsequent retaining frame corresponds to the limit groove on the limit disk.

[0013] By adopting the above technical scheme, after the retaining frame is placed on the assembly table, the control motor drives the control gear to rotate, and during the rotation of the control gear, the first control rack and the second control rack are driven to move simultaneously, the control surface on the first control rack first abuts against the moving plate, and then the moving plate and the proofreading plate are pushed to move simultaneously, the first return spring is in a stretched state, and then the mounting groove and the limit groove are made to correspond, when the mounting groove and the limit groove correspond, the moving plate will no longer abut against the control surface, at this time the second control rack and the mounting rod abut, during the movement of the first control rack and the second control rack, the position of the moving plate remains unchanged, at this time the second control rack will be pushed to move, and then it is convenient to push the mounting rod and the limit rod to move, so that the second return spring is in a stretched state, and the three limit plates are close to each other to adjust the position of the retaining frame, and finally the retaining frame and the limit plate are coaxially arranged, so as to achieve the purpose of facilitating the installation of rollers.

[0014] Optionally, the pushing assembly includes a pushing cam arranged on an assembly table, a pushing rod slidably connected to a limiting plate, a pushing block fixed on the pushing rod, and a pushing spring sleeved on the pushing rod, one end of the pushing spring is fixed to the assembly table, and the other end is fixed to the pushing rod, the pushing spring is used to drive the pushing block to move toward the center of the limiting plate, and make the pushing rod abut against the side surface of the pushing cam, the pushing cam is provided with a groove for abutting against the pushing rod, and the side surface of the pushing cam is provided with a connecting arc surface.

[0015] By adopting the above technical scheme, the roller feeding assembly places the roller in the installation groove and the limit groove. At this time, the pushing block is in the limit disk. Then, when the limit disk rotates, since the pushing cam does not rotate, the pushing rod in the groove will move to the side of the pushing cam. At this time, the pushing rod drives the pushing block to move away from the center of the circle of the limit disk, and the pushing block extends out of the limit disk. Then, it is convenient to push the roller in the limit groove to be clamped in the installation groove. At the same time, the adjacent pushing rod abutting against the side of the pushing cam will also abut against the inner wall of the groove. Under the action of the pushing spring, the pushing block is in the limit disk, and the corresponding limit groove will also correspond to the feeding assembly, thereby achieving the purpose of facilitating the installation of the roller into the limit groove and the installation groove.

[0016] Optionally, an adjustment component is provided on the assembly table, and the adjustment component is used to drive the pushing cam to move in the vertical direction. The adjustment component includes an adjustment rod rotatably connected to the pushing cam, an adjustment ring fixed on the adjustment rod, and an adjustment spring fixed on the assembly table, one end of the adjustment spring is fixed on the assembly table, and the other end is fixed on the pushing cam.

[0017] By adopting the above technical solution, when installing the inner ring, the inner ring is sleeved on the adjusting ring. When the inner ring moves toward the limit plate, the adjusting ring is first pushed to move. The movement of the adjusting ring pushes the pushing cam to move away from the limit plate, so that the adjusting spring is in a compressed state. Finally, the pushing rod and the pushing cam are disengaged, so that the pushing block is completely moved into the limit plate, and then makes way for the inner ring, which is convenient for installing the inner ring.

[0021] By adopting the above technical solution, under the action of the inclined surface, the upper end of the push block first contacts the roller, and then the vertical roller is tilted, and finally during the movement of the push block, the roller can be tilted and clamped in the installation groove.

DETAILED DESCRIPTION

[0032] The following combination Figure 1-Figure 7 This application is described in further detail.

[0033] The present application embodiment discloses a roller bearing assembly mechanism. Figures 1 to 7 A roller bearing assembly mechanism includes an assembly platform 01 and a limit plate 02 arranged on the assembly platform 01, a retaining frame is sleeved on the limit plate 02, and a control cylinder 03 is arranged on the assembly platform 01, and a roller feeding assembly 04 is arranged on the control cylinder 03, and the roller feeding assembly 04 is used to send the roller to the mounting groove 05 of the retaining frame and the limit groove 06 on the limit plate 02. In addition, a limit assembly 1 and a proofreading assembly 2 are arranged on the assembly platform 01, the limit assembly 1 is used to make the retaining frame and the limit plate 02 coaxially arranged, and the proofreading assembly 2 is used to make the mounting groove 05 on the retaining frame correspond to the limit groove 06 on the limit plate 02, and a pushing assembly 5 is arranged on the limit plate 02, and the pushing assembly 5 is used to push the roller in the limit groove 06 to completely move into the mounting groove 05 on the retaining frame. Since the roller feeding assembly 04 belongs to the prior art, in this embodiment, the specific working principle of the roller feeding assembly 04 is not described in detail.

[0034] Reference Figures 2 to 4 The proofreading assembly 2 includes a movable plate 21 slidably connected to the assembly table 01 and a proofreading plate 22 arranged on the movable plate 21. The proofreading plate 22 is arranged horizontally, and a proofreading surface 23 is arranged on the proofreading plate 22. There are two proofreading surfaces 23. Under the action of the two proofreading surfaces 23, the vertical cross-section of the proofreading plate 22 gradually becomes smaller along the direction close to the axis of the limit plate 02, so that the proofreading plate 22 is arranged in a triangular shape.

[0035] A proofreading spring 24 is arranged on the movable plate 21, one end of the proofreading spring 24 is fixed on the proofreading plate 22, and the other end is fixed on the movable plate 21, and the proofreading spring 24 pushes the proofreading plate 22 to move in the direction close to the limit plate 02. At the same time, a control component 3 is arranged on the assembly table 01, and the control component 3 is used to drive the movable plate 21 to slide on the assembly table 01, and then drive the proofreading plate 22 to move through the movable plate 21. During the movement of the proofreading plate 22, the proofreading surface 23 will abut against the side wall of the mounting groove 05, and finally push the retaining frame to rotate, so that the mounting groove 05 on the retaining frame corresponds to the limit groove 06 on the limit plate 02, and then the roller can be better placed in the mounting groove 05 through the roller feeding component 04.

[0036] Since the proofreading plate 22 is slidably connected to the movable plate 21, when the roller is in the installation groove 05 and the limit groove 06 at the same time, the limit plate 02 will drive the retaining frame to rotate during its rotation, and then the roller feeding assembly 04 can install the roller in the adjacent limit groove 06 and the installation groove 05. During the rotation of the retaining frame, the proofreading plate 22 can be pushed to move away from the limit plate 11, thereby facilitating the separation of the proofreading plate 22 and the installation groove 05. In addition, an electromagnet is arranged on the movable plate 21, and the end of the proofreading plate 22 away from the limit disk 02 is arranged to be made of iron material. After the retaining frame pushes the proofreading plate 22 to disengage from the mounting groove 05, the electromagnet is energized. At this time, the proofreading plate 22 is fixed on the movable plate 21, and the proofreading spring 24 is compressed. When the control component 3 drives the movable plate 21 to move away from the limit disk 02, the electromagnet is de-energized. At this time, under the action of the proofreading spring 24, the proofreading plate 22 is pushed to move toward the limit disk 02. Finally, it is convenient to adjust the position of the subsequent retaining frame so that the mounting groove 05 on the subsequent retaining frame corresponds to the limit groove 06 on the limit disk 02.

[0037] Reference Figures 2 to 7 The limit assembly 1 includes three limit plates 11 slidably connected to the assembly platform 01, a limit rod 12 slidably connected to the assembly platform 01 and a connecting rod 13 hinged on the limit rod 12. Three connecting rods 13 are provided, and the three connecting rods 13 correspond to the three limit plates 11 one by one. One end of the connecting rod 13 away from the limit rod 12 is hinged on the limit plate 11. When the limit rod 12 moves in the vertical direction, the three limit plates 11 can be driven to move simultaneously. Finally, the position of the retaining frame can be adjusted by the limit plate 11. Finally, the retaining frame and the limit plate 02 are coaxially arranged, and then it is convenient to install the roller in the mounting groove 05 and the limit groove 06.

[0038] Reference Figures 2 to 7 The side of the limit plate 11 close to the limit plate 02 is rotatably connected with an abutment ball (not shown in the figure). A plurality of abutment balls are arranged on each limit plate 11, and the abutment balls are used to contact the outer peripheral surface of the retaining frame. Then, when the limit plate 02 drives the roller and the retaining frame to move, the friction between the limit plate 11 and the retaining frame can be reduced. On the other hand, it is easier to rotate the retaining frame and can also reduce damage to the retaining frame.

[0039] Reference Figures 2 to 7The control assembly 3 includes a control rod 31 slidably connected to the assembly platform 01, a mounting rod 32 fixed on the limit rod 12, a first control rack 33 fixed on the control rod 31, a second control rack 34 slidably connected to the assembly platform 01, and a control gear 35 rotating on the assembly platform 01, the second control rack 34 is used to abut on the mounting rod 32, the control gear 35 and the first control rack 33 are meshed with the second control rack 34 at the same time, and a control motor is arranged on the assembly platform 01, the control motor is used to drive the control gear 35 to rotate, in this embodiment, the mounting rod 32 is arranged horizontally, the control rod 31 is arranged vertically, and a control surface 42 is arranged on the control rod 31, and the control surface 42 is gradually inclined toward the direction of the limit plate 02 along the direction close to the ground; in this embodiment, the movable plate 21 is arranged as a C-shaped structure, and a control groove 8 for inserting the control rod 31 is opened in a horizontal position, and the inner wall of the control groove 8 is used to abut against the control surface 42.

[0040] Reference Figures 2 to 7 A first return spring 4 is provided on the movable plate 21 for pushing the movable plate 21 to move away from the limit plate 02. One end of the first return spring 4 is fixed on the assembly platform 01, and the other end is fixed on the movable plate 21. A second return spring 41 is provided on the assembly platform 01 for driving the mounting rod 32 to move toward the limit plate 02. One end of the second return spring 41 is fixed on the assembly platform 01, and the other end is fixed on the mounting rod 32.

[0041] Reference Figures 2 to 7 After the retainer is placed on the assembly table 01, the control motor drives the control gear 35 to rotate. During the rotation of the control gear 35, the first control rack 33 and the second control rack 34 are driven to move simultaneously. The control surface 42 on the first control rack 33 first abuts against the inner wall of the control groove 8 on the movable plate 21, and then pushes the movable plate 21 and the proofreading plate 22 to move. The first return spring 4 is in a stretched state, and then the mounting groove 05 and the limit groove 06 are made to correspond. When the mounting groove 05 and the limit groove 06 correspond, the inner wall of the control groove 8 no longer abuts against the control surface 42. At this time, the second control rack 34 abuts against the mounting rod 32. During the continued movement of the first control rack 33 and the second control rack 34, the position of the movable plate 21 remains unchanged. At this time, the second control rack 34 will be pushed to move, and then it is convenient to push the mounting rod 32 and the limit rod 12 to move, so that the second return spring 41 is in a stretched state, and the three limit plates 11 are close to each other to adjust the position of the retainer, and finally the retainer and the limit plate 02 are coaxially arranged to achieve the purpose of facilitating the installation of the roller.

[0042] Reference Figures 2 to 7The pushing component 5 includes a pushing cam 51 arranged on the assembly platform 01, a pushing rod 52 slidably connected to the limiting disk 02, a pushing block 53 fixed on the pushing rod 52, and a pushing spring 54 sleeved on the pushing rod 52. One end of the pushing spring 54 is fixed on the assembly platform 01, and the other end is fixed on the pushing rod 52. The pushing spring 54 is used to drive the pushing block 53 to move toward the center of the limiting disk 02, and make the pushing rod 52 abut against the side of the pushing cam 51. In this embodiment, a plurality of pushing rods 52 and a plurality of pushing blocks 53 are provided, and a plurality of pushing rods 52 and a plurality of limiting grooves 06 are correspondingly provided.

[0043] Reference Figures 1 to 7 A groove 43 is provided on the pushing cam 51, and a connecting arc surface 44 is provided on the side of the pushing cam 51. The groove 43 and the side of the pushing cam 51 are connected by the connecting arc surface 44, and then it is convenient for the pushing rod 52 to move from the groove 43 to the side of the pushing cam 51, and it is also convenient for the pushing rod 52 to move from the side of the pushing cam 51 to the groove 43. Under the action of the pushing spring 54, the pushing rod 52 abuts against the inner wall of the groove 43. At this time, the pushing block 53 is completely in the limit plate 02, and in this embodiment, the groove 43 and the roller feeding assembly 04 are correspondingly arranged, and then it is convenient for the roller to fall into the limit groove 06 corresponding to the groove 43.

[0044] Reference Figures 1 to 7 The roller loading assembly 04 places the roller in the mounting groove 05 and the limiting groove 06. At this time, the pushing block 53 is in the limiting disk 02. Then, when the limiting disk 02 rotates, since the pushing cam 51 does not rotate, the pushing rod 52 in the groove 43 will move to the side of the pushing cam 51. At this time, the pushing rod 52 drives the pushing block 53 to move in the direction away from the center of the circle of the limiting disk 02, and the pushing block 53 extends out of the limiting disk 02. Then, it is convenient to push the roller in the limiting groove 06 to be clamped in the mounting groove 05. At the same time, the adjacent pushing rod 52 abutting against the side of the pushing cam 51 will also abut against the inner wall of the groove 43. Under the action of the pushing spring 54, the pushing block 53 is in the limiting disk 02, and the corresponding limiting groove 06 will also correspond to the roller loading assembly 04, thereby achieving the purpose of facilitating the installation of the roller into the limiting groove 06 and the mounting groove 05.

[0045] In order to facilitate the movement of the roller from the limiting groove 06 to the installation groove 05 along the inclined direction, an inclined surface 45 is provided on the side of the pushing block 53 away from the pushing rod 52, and the inclined surface 45 is inclined in the direction close to the ground toward the pushing rod 52; under the action of the inclined surface 45, the upper end of the pushing block 53 first contacts the roller, and then the vertical roller is tilted, and finally in the process of the movement of the pushing block 53, the roller can be tilted and clamped in the installation groove 05, and after the roller is completely clamped in the installation groove 05, a gap will be left on the side of the roller and the limiting plate 02, which is convenient for the inner ring to be inserted, so that it can be more convenient to install the inner ring.

[0046] Reference Figures 2 to 7 In order to facilitate the installation of the bearing inner ring, an adjustment component 6 is provided on the assembly table 01. The adjustment component 6 is used to drive the push cam 51 to move in the vertical direction, and then the end face of the push rod 52 can be completely separated from the push cam 51. At this time, under the action of the push spring 54, multiple push blocks 53 are moved to the limit plate 02 at the same time, and then when the inner ring is installed, the obstruction of the limit block to the inner ring can be reduced.

[0047] Reference Figures 2 to 7 The adjusting assembly 6 includes an adjusting rod 61 rotatably connected to the pushing cam 51, an adjusting ring 62 fixed on the adjusting rod 61, and an adjusting spring 63 fixed on the assembly platform 01. One end of the adjusting spring 63 is fixed on the assembly platform 01, and the other end is fixed on the pushing cam 51. The adjusting rod 61 is slidably connected to the limit plate 02 along the vertical direction. When installing the inner ring, the inner ring is sleeved on the adjusting ring 62. When the inner ring moves toward the limit plate 02, the adjusting ring 62 is first pushed to move. The movement of the adjusting ring 62 drives the pushing cam 51 to move away from the limit plate 02, so that the adjusting spring 63 is in a compressed state, and finally the pushing rod 52 and the pushing cam 51 are disengaged, so that the pushing block 53 is completely moved into the limit plate 02, and then the inner ring is given space to facilitate the installation of the inner ring. After the inner ring is installed, the inner ring and the retaining frame are moved in the opposite direction. When the retaining frame and the inner ring are taken out, the pushing cam 51 is driven to reset under the action of the adjusting spring 63, so that the subsequent pushing roller is moved into the installation groove 05.

[0048] In order to facilitate the reverse movement of the pushing cam 51, the pushing cam 51 can drive the pushing rod 52 to move, an adjusting surface 7 is provided at one end of the pushing rod 52, and a contact surface 71 is provided on the side of the pushing cam 51 facing away from the ground. When the pushing cam 51 moves toward the direction close to the limit plate 02, the contact surface 71 abuts against the adjusting surface 7, and then it is convenient to drive the pushing rod 52 to move, so that the adjusting spring 63 is in a stretched state.

[0049] A distance sensor is provided on the assembly platform 01, and the distance sensor is used to detect the distance between the bottom surface of the holder and the surface of the assembly platform 01. When the holder is placed on the assembly platform 01, the distance detected by the distance sensor is zero, and then the control component 3 is operated to adjust the position of the proofreading component 2 and the limit component 1. After the adjustment is completed, the holder and the limit plate 02 can be coaxially arranged, and the mounting groove 05 on the holder corresponds to the limit groove 06 on the limit plate 02. In addition, a driving motor is provided on the assembly platform 01, and the driving motor is used to connect with the limit plate 02 and can drive the limit plate 02 to rotate. In addition, a controller is provided on the assembly platform 01, and the controller is used to connect with the distance sensor, the electromagnet and the control motor.

[0050] The implementation principle of a roller bearing assembly mechanism in an embodiment of the present application is as follows: when assembling the roller bearing, first place the retainer on the surface of the assembly table 01, and then drive the control gear 35 to rotate by controlling the motor. At this time, the first control rack 33 will push the movable plate 21 and the proofreading plate 22 to move, so that the mounting groove 05 of the retainer corresponds to the limiting groove 06 on the limiting plate 02, and then the second control rack 34 will push the limiting plate 11 to move, and adjust the position of the retainer so that the retainer and the limiting plate 02 are coaxially arranged. After the retainer is adjusted, the roller is placed in the mounting groove 05 and the limiting groove 06 by the roller feeding assembly 04. Finally, under the action of the pushing cam 51 and the pushing block 53, the roller in the limiting groove 06 is pushed into the mounting groove 05 to fix the roller, and finally the inner ring can be easily installed. In addition, by adjusting the position of the retainer, the retainer and the limiting plate 02 can be coaxially arranged, and the mounting groove 05 and the limiting groove 06 can also be made to correspond, which makes it more convenient to install the retainer, thereby improving the assembly efficiency of the bearing.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
