Abstract
Description
Technical Field
[0001] This application relates to the field of roller mounting technology for cross bearings, and in particular to an auxiliary roller mounting device for mounting cross bearings. Background Technology
[0002] Cross bearings, as a high-precision transmission component, are widely used in industrial robot joints, precision turntables, automated testing equipment and other fields. Their assembly accuracy directly determines the operational stability and service life of the equipment. In the production and assembly process of cross bearings, the roller filling operation is one of the core processes. Especially for small cross bearings, the difficulty of roller filling is even higher due to the small size of the parts and the narrow assembly space.
[0003] In the existing technology, the roller installation of small and medium-sized crossed bearings is mostly carried out manually. The specific process is as follows: the operator uses a simple tool to manually tighten the inner ring of the bearing to achieve positioning, then the outer ring of the bearing is fitted on the outside of the inner ring, and the relative position of the inner and outer rings is adjusted so that the roller mounting holes face upward. Then, the rollers are loaded one by one into the raceway through the mounting holes. During this process, in order to ensure that all raceway positions can be filled smoothly, the operator needs to continuously manually rotate the inner or outer ring of the bearing to adjust the orientation of the mounting holes.
[0004] However, the above-mentioned manual assembly method has many significant drawbacks: First, it is difficult to accurately control the force of manually tightening the inner ring, which can easily cause the inner ring to shift, resulting in jamming during roller loading and reducing the assembly qualification rate; Second, during the manual rotation of the inner and outer rings, the rotation speed and direction cannot be kept stable, making it difficult to achieve continuous and efficient roller loading; Third, the entire assembly process depends on the operator's skill level.

[0023] The present application will be further described in detail below with reference to the accompanying drawings.
[0024] To better understand the technical solutions shown in the embodiments of this application, the roller mounting principle of small cross bearings in the prior art will be introduced first.
[0025] In the existing technology, the roller installation of small and medium-sized crossed bearings is mostly carried out manually. The specific process is as follows: the operator uses a simple tool to manually tighten the inner ring of the bearing to achieve positioning, then the outer ring of the bearing is fitted on the outside of the inner ring, and the relative position of the inner and outer rings is adjusted so that the roller mounting holes face upward. Then, the rollers are loaded one by one into the raceway through the mounting holes. During this process, in order to ensure that all raceway positions can be filled smoothly, the operator needs to continuously manually rotate the inner or outer ring of the bearing to adjust the orientation of the mounting holes.
[0026] Please see Figures 1-4This application discloses a roller auxiliary installation device for cross bearing installation, comprising a base 3, a servo motor 2 mounted on the upper part of one side wall of the base 3, a stepped installation shaft 1 mounted on the power output end of the servo motor 2, and an outwardly protruding roller 5 mounted on the stepped surface of the installation shaft 1. The stepped installation shaft 1 provides a close-fitting support surface for the bearing inner ring 6 and reserves reasonable space for the subsequent installation of the roller 5 and the arrangement of the clamping mechanism 8. It is the basic carrier for realizing the positioning and rotation drive of the bearing inner ring 6. Compared with manual rotation, the servo motor 2 can precisely control the speed and direction, providing controllable orientation adjustment for continuous roller loading. The installation shaft 1 has a built-in three-jaw pusher. The tensioning mechanism 8 includes a sliding cavity 82 formed within the mounting shaft 1. An electric actuator 84 is mounted on the middle of one side wall of the sliding cavity 82. The telescopic part of the electric actuator 84 is connected to a linkage shaft 83. Three connecting rods 85 are annularly mounted on the outer wall of the linkage shaft 83. Each connecting rod 85 has a top plate 81 connected to its end opposite to the linkage shaft 83. A groove 86 is formed on the mounting shaft 1 where it mates with the top plate 81. When the bearing inner ring 6 is fitted onto the mounting shaft 1 and located outside the top plate 81, the electric actuator 84 pushes the linkage shaft 83 to move. Simultaneously, the linkage shaft 83, with the help of the connecting rods 85, pushes the top plate 81 out of the groove 86 to contact and tighten with the bearing inner ring 6, thus ensuring reliable bearing inner ring 6. Tighten to ensure the inner ring 6 of the bearing is fixed relative to the mounting shaft 1; the inner ring 6 of the cross bearing is mounted on the mounting shaft 1 outside the top plate 81, and the outer ring 7 of the cross bearing is fitted outside the inner ring 6; a bidirectional synchronous centering clamping mechanism 9 is also mounted on the base 3 directly below the mounting shaft 1. The clamping mechanism 9 includes a guide rail 94 mounted on the base 3 directly below the mounting shaft 1, a bidirectional threaded rod 93 mounted in the middle of the guide rail 94, a motor 95 mounted on one side wall of the guide rail 94 opposite to the bidirectional threaded rod 93, and a clamping rod 92 mounted on each of the two oppositely threaded sections of the bidirectional threaded rod 93. The top of the clamping rod 92 is connected to a clamping device for clamping the outer ring 7 of the bearing. When the roller mounting holes on the outer ring 7 of the bearing are facing upwards, the double-threaded rod 93 is rotated by the motor 95. After the double-threaded rod 93 rotates, the two clamping rods 92 move synchronously and align under the action of the thread transmission. After the clamping plate 91 moves, it will clamp the outer ring 7 of the bearing. A limit mechanism 4 is installed on the lower part of one side wall of the clamping rod 92. The limit mechanism 4 includes a support plate 42 installed on the clamping rod 92. An electric push rod 41 is installed in the middle of the support plate 42. The telescopic part of the electric push rod 41 is connected to the limit plate 43. When the clamping rod 92 moves to the designated position, the limit plate 43 is pressed against the upper side of the guide rail 94 under the action of the electric push rod 41, which can ensure the stability of the position of the clamping rod 92 after it moves.
[0027] Specifically, in use, the roller mounting device for the cross bearing utilizes a servo motor 2 mounted on the base 3 and a stepped mounting shaft 1. The built-in three-jaw clamping mechanism 8 on the mounting shaft 1 automatically centers and clamps the inner ring 6 of the bearing, replacing manual positioning with high accuracy and stability. Simultaneously, a bidirectional synchronous clamping mechanism 9 is configured below the mounting shaft 1 to automatically center and clamp the outer ring 7 of the bearing, ensuring that the roller mounting holes on the outer ring 7 always face upwards, providing a stable position for roller loading. Furthermore, by setting rollers 5 on the stepped surface of the mounting shaft 1, the frictional resistance during the assembly of the inner ring 6 is reduced, achieving initial rapid positioning. The servo motor 2 drives the mounting shaft 1 to rotate, causing the bearing rings to rotate at a uniform speed, completing multi-directional roller loading without manual intervention, significantly improving assembly efficiency.
[0028] Please see Figures 1-2 Servo motor 2 is bolted to base 3, and servo motor 2 is connected to mounting shaft 1 via a coupling.
[0029] As one implementation method, the servo motor 2 is mainly used to provide power for the rotation of the mounting shaft 1. The coupling between the output shaft of the servo motor 2 and the mounting shaft 1 has a certain ability to compensate for eccentricity, which can effectively offset the coaxiality error generated during the installation process, ensure smooth power transmission, and avoid bending deformation of the mounting shaft 1 due to uneven force.
[0030] Please see Figure 1 , Figure 2 and Figure 4 The roller 5 is rotatably coupled with the mounting shaft 1, and the roller 5 is distributed in a ring on the mounting shaft 1.
[0031] In one implementation, the outer side of the roller 5 protrudes from the stepped surface of the mounting shaft 1, ensuring that when the inner ring 6 of the bearing is fitted onto the mounting shaft 1, the side wall of the inner ring 6 can reliably contact the roller 5. At the same time, the rotation of the roller 5 relative to the mounting shaft 1 can reduce the frictional resistance between the inner ring 6 of the bearing and the side of the mounting shaft 1 when it rotates relative to the outer ring 7 of the bearing. In addition, the included angle between adjacent rollers 5 is equal, so that the inner ring 6 of the bearing can make uniform contact with the roller 5 when it is fitted onto the mounting shaft 1, avoiding tilting and jamming, and realizing the rapid installation of the inner ring 6 of the bearing onto the mounting shaft 1.
[0032] Please see Figure 2 and Figure 3 The electric actuator 84 is installed on one side wall of the slide cavity 82 along the length of the slide cavity 82, and the telescopic part of the electric actuator 84 is bolted to the linkage shaft 83.
[0033] In one implementation, the axis of the electric actuator 84 coincides with the axis of the mounting shaft 1, ensuring that the thrust direction is distributed along the center of the mounting shaft 1; the linkage shaft 83 is a stepped shaft, and the connection between the linkage shaft 83 and the electric actuator 84 is a planar structure, to ensure that the extension and retraction of the electric actuator 84 can be accurately transmitted to the linkage shaft 83, avoiding motion lag.
[0034] Please see Figure 2 One end of the connecting rod 85 is rotatably engaged with the top plate 81, and the other end of the connecting rod 85 is rotatably engaged with the linkage shaft 83.
[0035] In one implementation, when the linkage shaft 83 moves along the axis under the drive of the electric actuator 84, the three connecting rods 85 simultaneously push or pull the top plate 81 to make radial extension and retraction movements along the slide groove 86, thereby tightening or loosening the inner ring 6 of the bearing. The synchronization error of the movement of the three top plates 81 is small and can be ignored, so as to ensure accurate centering.
[0036] Please see Figure 1 and Figure 2 The top plate 81 and the slide groove 86 are in sliding fit, and a rubber pad is installed on the side wall of the top plate 81 that contacts the inner ring 6 of the bearing.
[0037] As one implementation method, the top plate 81 has an arc-shaped cross-section, and its bottom slides into the groove 86 to prevent the top plate 81 from falling off during movement. The rubber pad on the top plate 81 has anti-slip texture, which can increase the friction with the inner wall of the bearing inner ring 6, prevent relative sliding between the bearing inner ring 6 and the top plate 81 during assembly, and avoid direct metal contact that could scratch the surface of the bearing inner ring 6, thus protecting the bearing precision.
[0038] Please see Figures 1-3 The guide rail 94 is mounted on the base 3, and the bidirectional threaded rod 93 is rotatably engaged with the guide rail 94.
[0039] In one implementation, the length direction of the guide rail 94 is perpendicular to the axis of the mounting shaft 1, so that the bidirectional threaded rod 93 rotates with the guide rail 94, ensuring the stability of the axis when the bidirectional threaded rod 93 rotates, avoiding radial runout, and providing precise guidance for the synchronous movement of the clamping rod 92.
[0040] Please see Figures 1-4 The motor 95 is installed in the middle of one side wall of the guide rail 94. The motor 95 is connected to the bidirectional threaded rod 93 by a coupling. The bidirectional threaded rod 93 passes through the clamp rod 92 and is threadedly connected to the clamp rod 92. The clamp rod 92 has a bent structure and is bolted to the clamp plate 91. The clamp plate 91 has an arc-shaped structure.
[0041] In one implementation, when the bidirectional threaded rod 93 rotates, the two reverse threads drive the clamping rods 92 on both sides to move in opposite directions or away from each other along the guide rail 94, so that the clamping plate 91 is an arc-shaped structure adapted to the outer wall of the bearing outer ring 7, and its curvature is consistent with the radius of curvature of the bearing outer ring 7, thereby increasing the contact area between the clamping plate 91 and the bearing outer ring 7 and making the clamping more stable.
[0042] Please see Figures 1-3 The support plate 42 is welded to the clamping rod 92, the fixing part of the electric push rod 41 is bolted to the support plate 42, and the telescopic part of the electric push rod 41 is bolted to the limiting plate 43.
[0043] As one implementation method, the electric actuator 41 is mainly used to provide power for the movement of the limiting plate 43. When the clamping plate 91 clamps the outer ring 7 of the bearing into place, the electric actuator 41 extends to push the limiting plate 43 against the upper part of the guide rail 94, forming a stable "upper and lower clamping" structure to prevent the outer ring 7 of the bearing from rotating or axially displacing when the mounting shaft 1 rotates.
[0044] The specific working principle is as follows: When installing the cross bearing rollers, the device is first connected to the external power supply and control components, and each actuator is reset to its initial state: at this time, the electric push rod 84 is in the retracted state, driving the linkage shaft 83 and connecting rod 85 to retract the three top plates 81 into the slide groove 86, with the top of the top plate 81 not exceeding the outer circle surface of the mounting shaft 1; the drive motor 95 drives the bidirectional threaded rod 93 to rotate, so that the clamping rods 92 on both sides are in the maximum open state; the electric push rod 41 is in the retracted state, the limit plate 43 is away from the center area of the guide rail 94, and at the same time the servo motor 2 is in the standby state, and the mounting shaft 1 remains stationary; then the bearing inner ring 6 with the bearing outer ring 7 of the roller to be assembled is installed on the mounting shaft 1 until the bearing outer ring 7 and the side wall of the bearing inner ring 6 are connected. At the contact position with roller 5, the operator then controls the electric actuator 84 to extend via the external control panel, pushing the linkage shaft 83 to move along the axis of the slide cavity 82 towards the end of the mounting shaft 1. The linkage shaft 83, through three connecting rods 85, synchronously pushes the top plate 81 to move radially outward along the slide groove 86. The rubber pad on the outer side of the top plate 81 gradually contacts the inner wall of the bearing inner ring 6. When the top plate 81 contacts the inner wall of the bearing inner ring 6, the electric actuator 84 stops extending and maintains the thrust. At this time, the bearing inner ring 6 achieves precise centering under the uniform tension of the three top plates 81, and its axis coincides with the axis of the mounting shaft 1, completing the fixing of the bearing inner ring 6. After the bearing inner ring 6 is tightened and positioned, the motor 95 is energized and rotated, driving the bidirectional threaded rod 93 to rotate synchronously. The two threads of the bidirectional threaded rod 93 have opposite directions of rotation. The two clamping rods 92 on both sides move synchronously towards each other along the guide rail 94, causing the arc-shaped clamping plate 91 to gradually approach the outer wall of the bearing outer ring 7. When the clamping plate 91 contacts the outer wall of the bearing outer ring 7, the motor 95 continues to rotate until the clamping force reaches the preset value. The motor 95 then stops rotating and locks, achieving the centering clamping of the outer bearing outer ring 7. Subsequently, the electric push rod 41 is energized and extends, pushing the limiting plate 43 downward to press against the upper part of the guide rail 94, forming a stable clamping and fixing structure, providing a fixed position for roller loading. After the bearing outer ring 7 is clamped and limited, the servo motor 2 is energized and rotates, driving the mounting shaft 1 and the already centered bearing inner ring 6 to rotate at a uniform speed through the coupling. Since the bearing outer ring 7 is clamped and fixed and the mounting hole always faces upward, When the inner ring 6 of the bearing rotates, causing the cage of the cross bearing to rotate synchronously, the roller mounting positions on the cage will align sequentially with the mounting holes of the outer ring 7 of the bearing. The operator can continuously load the rollers into the mounting holes without frequently adjusting the bearing position, thus achieving continuous loading of rollers in multiple directions. During the loading process, the rolling friction between the roller 5 and the inner ring 6 of the bearing, as well as the stable clamping of the clamping plate 91, ensures that the inner ring 6 of the bearing rotates smoothly, avoiding jamming during roller loading. After all rollers are loaded, the servo motor 2 stops rotating, and each actuator resets in a preset sequence: the electric push rod 41 retracts first, causing the limit plate 43 to disengage from the upper part of the guide rail 94; then the motor 95 rotates in the opposite direction, causing the clamping rod 92 and the clamping plate 91 to open, releasing the outer ring 7 of the bearing.Finally, the electric actuator 84 retracts, causing the top plate 81 to retract and releasing the tension on the inner ring 6 of the bearing. The operator can then easily remove the assembled cross bearing from the mounting shaft 1, completing one assembly operation. The device can then proceed to the next work cycle. Under this device, the inner ring 6 of the bearing is automatically centered and tensioned by the built-in three-jaw clamping mechanism 8 on the mounting shaft 1 during the installation of the cross bearing rollers, replacing manual positioning. This provides high positioning accuracy and strong stability. Simultaneously, a bidirectional synchronous clamping mechanism 9 is configured below the mounting shaft 1 to automatically center and clamp the outer ring 7 of the bearing, ensuring that the roller mounting holes on the outer ring 7 always face upwards, providing a stable position for roller loading. Furthermore, by setting rollers 5 on the stepped surface of the mounting shaft 1, the frictional resistance during the assembly of the inner ring 6 is reduced, achieving initial rapid positioning. The servo motor 2 drives the mounting shaft 1 to rotate, causing the bearing rings to rotate at a uniform speed, completing multi-directional roller loading without manual intervention, thus significantly improving the assembly efficiency of the cross bearing rollers.
