Description

Technical Field

[0001] This invention relates to the field of bearing assembly technology, specifically to a ball bearing cage mounting device for industrial robots. Background Technology

[0002] The ball bearing cage mounting device for industrial robots is a key piece of equipment in bearing production. Its core technology lies in achieving high-precision assembly of balls and cages through mechanical automation and intelligent control. As industrial robots develop towards higher precision and higher load, the performance improvement and intelligent upgrade of this device will become an important force driving industry progress.

[0003] Patent CN201059321Y discloses a bearing cage installation machine, belonging to the field of bearing assembly equipment technology. It includes an automatic transmission installed in the frame and driven by a motor. The automatic transmission is connected to a push rod installed on the frame. A lower mold is installed on the push rod, and an upper mold is installed on a support frame above the lower mold. This patented bearing cage installation machine has a simple structure, fast and accurate cage installation, low labor intensity, improved production efficiency, and reduced production costs.

[0004] However, when using the above-mentioned device, it is difficult to simultaneously limit and control the balls during the rapid installation of the bearing cage, which can easily cause the balls inside the bearing to move, resulting in a reduction in the cage installation efficiency. Therefore, an industrial robot bearing cage ball installation device is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an industrial robot bearing cage ball mounting device to address the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an industrial robot bearing cage ball bearing mounting device, including a base, an electric slide rail fixedly connected to the inner wall of the base, a moving platform fixedly connected to the moving end of the electric slide rail, an electric push rod fixedly connected to the top of the base, a slotted frame fixedly connected to the top of the moving platform, a connecting plate fixedly connected to the output end of the electric push rod, an elastic telescopic rod fixedly connected to the front of the connecting plate, a clamping arc plate fixedly connected to the telescopic end of the elastic telescopic rod, and a stop plate fixedly connected to the front of the connecting plate. A long push rod is fixedly connected to the right side. A slider is slidably connected to the inner wall of the slot frame. A pull rod is rotatably connected to the circumference of the slider. A roller column is rotatably connected to the inner wall of the pull rod. A connecting column is fixedly connected to the inner wall of the slider. A horizontal plate is fixedly connected to the inner wall of the connecting column. A ball-dividing slot plate is fixedly connected to the top of the horizontal plate. A motor is installed on the inner wall of the slot frame. A retainer pressing device is installed on the top of the base. An electric ball divider is installed on the top of the base. A bearing for installing a retainer is placed on the top of the moving platform. A protective mechanism for protection and isolation is provided on the inner wall of the slot frame. The bottom of the moving platform is equipped with a smoothing mechanism for improving the smooth flow of the ball bearings. The abutment plate contacts the clamping arc plate and is used to fix the bearing. The roller column contacts the moving platform and is used to reduce motion friction. The roller column is located on the movement trajectory of the long push rod. The connecting column contacts the moving platform and is used to drive the horizontal plate upward. The ball-dividing groove plate contacts the moving platform and is used to limit the movement of the ball bearings. This mechanism can limit and clamp the bearing at the top of the moving platform, improving the stability of the device during cage installation. The device improves installation efficiency, enhances cage installation stability, prevents displacement or vibration, and increases the accuracy of cage installation. The movement of the ball separator plate limits the internal balls of the bearing after the electric ball separator completes ball separation, keeping the balls in the same state as when separated by the electric ball separator. This prevents the balls from shifting due to external vibrations after separation, thus avoiding the need to restart the electric ball separator. The device also increases cage installation speed, improves installation accuracy, and reduces installation costs.

[0007] Preferably, the protective mechanism includes a reciprocating screw, a limiting post, a connecting block, and an isolation plate. The reciprocating screw is rotatably connected to the inner wall of the slot frame, the limiting post is fixedly connected to the inner wall of the slot frame, the connecting block is movably connected to the circumferential surface of the reciprocating screw, and the isolation plate is fixedly connected to the front of the connecting block, and the isolation plate is used to isolate surrounding personnel from the installation area. The protective mechanism also includes a fixing block, a rotating post, and an inner pressure block. The fixing block is fixedly connected to the bottom of the bead-separating slot plate, the rotating post is rotatably connected to the inner wall of the fixing block via a torsion spring, the inner pressure block is fixedly connected to the circumferential surface of the rotating post, and the inner pressure block is used for initial limiting control of the inner shaft. The connecting block slides... The moving connection is on the circumferential surface of the limiting post, and the limiting post is used to limit the connecting block. The number of isolation plates is set to two, and the two isolation plates are symmetrically distributed on the top of the moving table. The reciprocating screw is fixedly connected to the output end of the motor, so that the isolation plates can isolate and protect the area where the bearing cage is installed. This can prevent the flying of parts debris during the installation of the cage due to sudden accidents, which could cause safety hazards to the surrounding production personnel. Fixing and limiting the inner ring of the bearing can keep the bearing as a whole concentric. After fixing the inner ring, it can ensure that its relative position is accurate and avoid offset or tilt during installation, thereby ensuring the correct installation of the balls and the cage and improving the installation accuracy of the device.

[0008] Preferably, the smoothing mechanism includes a second elastic telescopic rod, a buffer arc plate, and a stop block. The second elastic telescopic rod is fixedly connected to the top of the clamping arc plate, the buffer arc plate is fixedly connected to the telescopic end of the second elastic telescopic rod, and the stop block is fixedly connected to the inner wall of the clamping arc plate. The stop block is used to control and clamp the external bearing. The smoothing mechanism also includes a connecting rod, a pressure column, and a lubricating sponge block. The connecting rod is fixedly connected to the inner wall of the fixing block, the pressure column is fixedly connected to the top of the connecting rod, and the lubricating sponge block is fixedly connected to the circumferential surface of the pressure column. The lubricating sponge block is located directly below the bearing balls. The lubricating sponge block is used to lubricate the bearing balls, ensuring that the buffer arc plate is positioned above the bearing surface. This prevents damage to the bearing surface caused by misalignment of the stamping position during cage pressing. It improves the device's performance, reduces production costs, and lowers the cost of damage during production, thus increasing the device's economic efficiency. The lubricating sponge block deforms, allowing it to apply internal lubricant to the ball surface, reducing friction during cage installation and helping the balls distribute evenly within the cage, thereby improving the cage installation accuracy.

[0009] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This industrial robot bearing cage ball bearing installation device, through the coordinated movement of the base, electric slide rail, moving table, electric push rod, slotted frame, connecting plate, elastic telescopic rod, clamping arc plate, abutment plate, long push rod, slider, pull rod, roller column, connecting column, horizontal plate, and ball-separating slot plate, can limit and clamp the bearing on the top of the moving table. This improves the stability and efficiency of the device during cage installation, prevents displacement or vibration, and enhances the accuracy of the device in installing the bearing cage. The movement of the ball-separating slot plate can limit the internal balls of the bearing after the electric ball separator has finished separating the balls, keeping the balls in the state separated by the electric ball separator. This avoids the balls shifting due to external vibration after separation, which would require restarting the electric ball separator. This increases the speed of cage installation, improves the installation accuracy, and reduces the production cost of the device.

[0010] 2. This industrial robot bearing cage ball mounting device, through the coordinated movement of the reciprocating screw, limiting column, connecting block, isolation plate, fixing block, rotating column, and inner pressure block, enables the isolation plate to isolate and protect the area where the bearing cage is installed. This prevents the flying of parts debris during the installation process from causing safety hazards to surrounding production personnel due to sudden accidents. The device also fixes and limits the inner ring of the bearing, ensuring the concentricity of the entire bearing. After fixing the inner ring, it ensures accurate relative position and avoids offset or tilting during installation, thereby guaranteeing the correct installation of the balls and cage and improving the installation accuracy of the device.

[0011] 3. This industrial robot bearing cage ball bearing installation device, through the coordinated movement of the elastic telescopic rod, buffer arc plate, abutment block, connecting rod, pressure column, and lubricating sponge block, ensures that the buffer arc plate is positioned above the bearing surface. This prevents the bearing surface from being damaged due to misalignment during the cage pressing process, thus improving the device's performance, reducing production costs, and minimizing damage costs. The device also deforms the lubricating sponge block, allowing it to apply internal lubricant to the ball surface, reducing friction during cage installation, promoting even ball distribution within the cage, and improving the cage installation accuracy.

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Please see Figures 1-9One embodiment of the present invention is: an industrial robot bearing cage ball bearing mounting device, comprising a base 1, an electric slide rail 2 fixedly connected to the inner wall of the base 1, a moving platform 3 fixedly connected to the moving end of the electric slide rail 2, an electric push rod 4 fixedly connected to the top of the base 1, a slot frame 5 fixedly connected to the top of the moving platform 3, a connecting plate 8 fixedly connected to the output end of the electric push rod 4, an elastic telescopic rod 9 fixedly connected to the front of the connecting plate 8, a clamping arc plate 10 fixedly connected to the telescopic end of the elastic telescopic rod 9, and a stop plate 11 fixedly connected to the front of the connecting plate 8. A long push rod 12 is fixedly connected to the right side of plate 8. A slider 13 is slidably connected to the inner wall of the slot frame 5. A pull rod 14 is rotatably connected to the circumferential surface of slider 13. A roller column 15 is rotatably connected to the inner wall of pull rod 14. A connecting column 16 is fixedly connected to the inner wall of slider 13. A horizontal plate 17 is fixedly connected to the inner wall of connecting column 16. A ball-dividing slot plate 18 is fixedly connected to the top of horizontal plate 17. A motor is installed on the inner wall of slot frame 5. A retainer pressing device is installed on the top of base 1. An electric ball divider is installed on the top of base 1. A bearing that needs to be installed with a retainer is placed on the top of moving table 3. When the device is activated, the robotic arm places the bearing for which the cage needs to be installed on the top of the moving platform 3. At this time, the electric slide rail 2 will activate, driving the moving platform 3 to move. The movement of the moving platform 3 will move the slot frame 5, and simultaneously, the moving platform 3 will move the top bearing to directly below the cage pressing device. At this time, the electric push rod 4 will activate, and its output end will move the connecting plate 8. The movement of the connecting plate 8 will move the elastic telescopic rod 9, which in turn will move the clamping arc plate 10. Simultaneously, the movement of the connecting plate 8 will also move the abutment plate 11. When the clamping arc plate 10 moves... After a certain distance, the clamping arc plate 10 will contact the bearing placed on the top of the moving platform 3. At this time, the clamping arc plate 10 will continue to move. The movement of the clamping arc plate 10 will cause the bearing reaction force to squeeze the elastic telescopic rod 9. At this time, the clamping arc plate 10 will move closer to the abutment plate 11. When the abutment plate 11 contacts the surface of the bearing, the connecting plate 8 stops moving. The movement of the abutment plate 11 and the clamping arc plate 10 can limit and clamp the bearing on the top of the moving platform 3, which can improve the stability of the device in the installation of the cage, improve the installation efficiency of the device, improve the stability of the cage installation process, prevent displacement or vibration, and improve the accuracy of the device in installing the cage on the bearing. The inner wall of the slot frame 5 is provided with a protective mechanism 6 for protection and isolation. The bottom of the moving table 3 is provided with a smoothing mechanism 7 for lifting the balls smoothly. The abutment plate 11 contacts the clamping arc plate 10 and is used to fix the bearing. The roller column 15 contacts the moving table 3 and is used to reduce the friction of movement. The roller column 15 is located on the movement trajectory of the long push rod 12. The connecting column 16 contacts the moving table 3 and is used to drive the horizontal plate 17 to rise. The ball dividing slot plate 18 contacts the moving table 3 and is used to limit the balls. After the electric ball separator completes the ball separation within the bearing, the connecting plate 8 moves, causing the long push rod 12 to move as well. After moving a certain distance, the long push rod 12 contacts the roller column 15 and continues to move, pushing the roller column 15 to move further. This movement of the roller column 15 causes the pull rod 14 to change angle, pushing the slider 13 upward. The upward movement of the slider 13 causes the connecting column 16 to rise, which in turn causes the horizontal plate 17 to rise. The movement of plate 17 will drive the ball-separating groove plate 18 to move. After rising a certain distance, the ball-separating groove plate 18 will contact the internal balls of the bearing and keep the balls stationary in the circular groove of the ball-separating groove plate 18. The movement of the ball-separating groove plate 18 can limit the internal balls of the bearing after the electric ball separator has finished separating the balls, so that the balls can maintain the state of the balls separated by the electric ball separator. This can prevent the balls from moving due to external vibration after the electric ball separator has finished separating the balls, which would cause the state of the balls to change and require restarting the electric ball separator. This can improve the installation speed of the cage of the device, improve the installation accuracy of the device, and reduce the installation and production costs of the device.

[0016] Overall working principle: When the connecting plate 8 stops moving, the movement of the abutment plate 11 and the clamping arc plate 10 can limit and clamp the bearing on the top of the moving table 3, which can improve the stability of the device in the installation of the cage, improve the installation efficiency of the device, improve the stability of the cage installation process, prevent displacement or vibration, and improve the accuracy of the device in installing the bearing cage. The ball separator plate 18 will contact the internal balls of the bearing and keep the balls stationary in the circular groove of the ball separator plate 18. The movement of the ball separator plate 18 can limit the internal balls of the bearing after the electric ball separator has finished separating the balls, so that the balls can maintain the state of the balls separated by the electric ball separator. This can prevent the balls from moving due to external vibration after the electric ball separator has finished separating the balls, which would cause the state of the balls to change and require restarting the electric ball separator. This can improve the speed of cage installation, improve the installation accuracy of the device, and reduce the production cost of the device.

[0017] Please see Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, the protective mechanism 6 includes a reciprocating screw 601, a limiting post 602, a connecting block 603, and an isolation plate 604. The reciprocating screw 601 is rotatably connected to the inner wall of the slot frame 5, the limiting post 602 is fixedly connected to the inner wall of the slot frame 5, the connecting block 603 is movably connected to the circumferential surface of the reciprocating screw 601, and the isolation plate 604 is fixedly connected to the front of the connecting block 603, and the isolation plate 604 is used to isolate surrounding personnel from the installation area. When the device is started, the motor starts, and the output of the motor drives the reciprocating screw 601 to rotate. The rotation of the reciprocating screw 601 drives the connecting block 603. However, the connecting block 603 slides on the circumferential surface of the limiting post 602. The limiting post 602 limits the connecting block 603 during the rotation of the reciprocating screw 601. The limiting post 602 causes the connecting block 603 to move laterally through the reciprocating groove on the surface of the reciprocating screw 601 during the rotation of the reciprocating screw 601. At this time, the lateral movement of the connecting block 603 will drive the isolation plate 604 to move. After moving a certain distance, the isolation plate 604 can isolate and protect the area where the bearing cage is installed, which can prevent the flying of parts debris during the installation of the cage and avoid safety hazards to the surrounding production personnel in case of sudden accidents. The protective mechanism 6 also includes a fixed block 605, a rotating column 606, and an inner pressure block 607. The fixed block 605 is fixedly connected to the bottom of the ball groove plate 18. The rotating column 606 is rotatably connected to the inner wall of the fixed block 605 by a torsion spring. The inner pressure block 607 is fixedly connected to the circumferential surface of the rotating column 606 and is used to perform preliminary limit control on the inner shaft. The connecting block 603 is slidably connected to the circumferential surface of the limiting column 602 and is used to limit the connecting block 603. The number of isolation plates 604 is set to two, and the two isolation plates 604 are symmetrically distributed on the top of the moving table 3. The reciprocating screw 601 is fixedly connected to the output end of the motor. When the device is started, the rising of the connecting column 16 will drive the horizontal plate 17 to rise. The movement of the horizontal plate 17 will drive the ball-dividing groove plate 18 to move. During the rising process, the ball-dividing groove plate 18 will drive the fixed block 605 to move. The movement of the fixed block 605 will drive the rotating column 606 to move. The movement of the rotating column 606 will drive the inner pressure block 607 to rise. When the internal balls of the bearing enter the groove of the ball-dividing groove plate 18 for limiting, the inner pressure block 607 will simultaneously contact the inner ring of the bearing. Through the torsion spring reset characteristic of the rotating column 606, the inner ring of the bearing will be fixed and limited, which can keep the bearing as a whole concentric. After the inner ring is fixed, its relative position is ensured to be accurate, avoiding offset or tilt during installation, thereby ensuring the correct installation of the balls and cage and improving the installation accuracy of the device. The smooth mechanism 7 includes a second elastic telescopic rod 701, a buffer arc plate 702, and a stop block 703. The second elastic telescopic rod 701 is fixedly connected to the top of the clamping arc plate 10, the buffer arc plate 702 is fixedly connected to the telescopic end of the second elastic telescopic rod 701, and the stop block 703 is fixedly connected to the inner wall of the clamping arc plate 10. The stop block 703 is used to control and clamp the external bearing. When the device is started, the movement of the clamping arc plate 10 will drive the movement of the elastic telescopic rod 701, which in turn will drive the movement of the buffer arc plate 702. At the same time, the movement of the clamping arc plate 10 will drive the movement of the abutment block 703. After the clamping arc plate 10 fixes and limits the bearing as a whole, the buffer arc plate 702 can be located above the bearing surface. This can prevent the stamping position from shifting during the cage pressing process, which could cause damage to the bearing surface. This can improve the effectiveness of the device, reduce production costs, reduce production damage costs, and improve the economic benefits of the device. The smooth mechanism 7 also includes a connecting rod 704, a pressure column 705, and a lubricating sponge block 706. The connecting rod 704 is fixedly connected to the inner wall of the fixing block 605, the pressure column 705 is fixedly connected to the top of the connecting rod 704, and the lubricating sponge block 706 is fixedly connected to the circumferential surface of the pressure column 705. The lubricating sponge block 706 is located directly below the bearing balls and is used to lubricate the bearing balls. During the use of the device, the upward movement of the fixed block 605 will drive the connecting rod 704 to rise. The movement of the connecting rod 704 will drive the pressure column 705 to rise. The movement of the pressure column 705 will drive the lubricating sponge block 706 to move. After rising a certain distance, the lubricating sponge block 706 can contact the ball before the connecting rod 704. At this time, the upward movement of the lubricating sponge block 706 and the reaction force of the ball can cause the lubricating sponge block 706 to deform. At this time, the lubricating sponge block 706 can apply the internal lubricating oil to the surface of the ball, which can reduce the friction during the cage installation process, help the ball to be evenly distributed in the cage, and improve the installation accuracy of the cage of the device.

[0018] Overall working principle: The isolation plate 604 isolates and protects the area where the bearing cage is installed, preventing the splashing of parts and debris during cage installation, thus avoiding safety hazards to surrounding production personnel. It also ensures the concentricity of the bearing as a whole, ensuring accurate relative position after the inner ring is fixed, preventing offset or tilting during installation, thereby guaranteeing the correct installation of the balls and cage and improving the installation accuracy of the device. The buffer arc plate 702 is located above the bearing surface, preventing the pressing position from shifting during the cage pressing process, which could damage the bearing surface. This improves the effectiveness of the device, reduces production costs, and increases the economic efficiency of the device. It also causes the lubricating sponge block 706 to deform, allowing the internal lubricating oil to be applied to the surface of the balls, reducing friction during cage installation and helping the balls to be evenly distributed in the cage, thus improving the installation accuracy of the cage.
