Description

Technical Field

[0001] This invention relates to the field of bearing pinning mechanism technology, specifically a dual-station bearing pinning mechanism. Background Technology

[0002] With the large-scale production of downstream manufacturing industries, the market demand for bearings continues to surge, which places higher demands on the efficiency of bearing assembly. As the core process of bearing assembly, the efficiency of pin mounting directly determines the overall production capacity of bearings. Traditional pin mounting methods are gradually becoming unable to keep up with the pace of mass production.

[0003] Patent CN210548243U discloses a wheel hub bearing hole machining device, including a machining platform, a clamping mechanism mounted on the machining platform for fixing the wheel hub to be machined, and a cutting mechanism for machining the bearing holes on both sides of the wheel hub. The cutting mechanism includes a dual-station opposing feed mechanism symmetrically arranged on both sides of the clamping mechanism and an adjusting mechanism for adjusting the feed amount of the dual-station opposing feed mechanism. The adjusting mechanism is mounted on the machining platform, and the dual-station opposing feed mechanism is slidably connected to the adjusting mechanism. This invention utilizes a dual-station synchronous tool set to simultaneously process bearing holes on both sides of a wheel hub, effectively improving the coaxiality of the bearing holes. Simultaneously, a clamping mechanism secures the wheel hub to be processed, avoiding secondary clamping and eliminating positioning errors caused by multiple clamping operations. This ensures that the circular runout of the processed holes is minimized. Furthermore, a lifting tool station adjustment unit adjusts the processing distance and height of the dual-station synchronous tool set according to the wheel hub specifications, resulting in high versatility. However, while this device adjusts the processing distance and height of the dual-station synchronous tool set according to the wheel hub specifications, it requires continuous parameter adjustment when fixing the bearing sleeve, which can lead to prolonged installation time. Additionally, it is difficult to guarantee that the bearing sleeve will not shift during pin installation, and pin jamming may occur during operation. Therefore, a dual-station bearing pin installation mechanism is proposed to solve the aforementioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a dual-station bearing pin loading mechanism to address the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a dual-position bearing needle loading mechanism, including a worktable, an electric sliding plate mounted on the top of the worktable, a step fixedly connected to the top of the electric sliding plate, a needle pusher installed on the inner wall of the step, an electric push plate fixedly connected to the top of the step, a motor fixedly connected to the top of the electric sliding plate, a cylinder assembly fixedly connected to the output end of the motor, a T-shaped plate fixedly connected to the output end of the motor, a needle loading platform fixedly connected to the top of the worktable, and a needle lowering device fixedly connected to the top of the needle loading platform. The needle-pushing cylinder has its circumferential surface in contact with the inner wall of the needle-loading platform. The front and rear sides of the needle-loading platform are equipped with anti-loosening positioning mechanisms, and the left side of the needle-loading platform is equipped with an anti-blocking mechanism to prevent jamming. When loading needles, when the operator moves the bushing to the front of the mechanism, the cylinder group is activated to make the bearing contact with the needle-pushing cylinder and load the roller needle into the bushing. Continuous operation reduces the interval of manual intervention, can adapt to the production line cycle, meet the needs of mass production, and can quickly switch the needle loading parameters of different bearing models without major modification to the mechanical structure, further improving the needle loading efficiency of the equipment. The workbench includes a T-shaped plate, an annular plate slidably connected to the inner wall of the T-shaped plate via a spring, a clamping plate rotatably connected to the inner wall of the annular plate via a torsion spring, a cylinder rotatably connected to the inner wall of the clamping plate, a pressing rod fixedly connected to the right side of the annular plate, and a fixing sleeve fixedly connected to the right side of the T-shaped plate. The output end of the electric push plate is fixedly connected to the circumferential surface of the push cylinder, and the circumferential surface of the cylinder contacts the inclined surface of the T-shaped plate. During needle loading, the T-shaped plate drives the clamping plate to rotate and contact the bearing sleeve, thereby further fixing it and avoiding tilting or displacement of the bearing sleeve caused by manual pressing. This ensures the coaxiality and positional accuracy requirements of subsequent processes such as needle loading and pressing, reduces the skill requirements of operators, reduces human error, and significantly improves the accuracy of needle loading.

[0006] Preferably, the positioning mechanism includes an L-shaped rod, which is fixedly connected to both sides of the output end of the step. A pulley is installed on the side of the L-shaped rod away from the step. A fixing plate is fixedly connected to the left side of the needle loading table, and a positioning plate is slidably connected to the left side of the needle loading table. Guide plates are fixedly connected to the front and rear sides of the positioning plate. The guide plates contact the front and rear sides of the needle loading table. While loading the needle, the step drives the positioning plate to move down, which, together with the fixing plate, assists in positioning the bearing sleeve. This ensures that the spacing, angle, and depth of the needle body in the bearing sleeve raceway are consistent, improving the positioning accuracy and achieving zero-gap positioning between the bearing and the inner hole of the workpiece. This ensures that the bearing does not deviate when entering the workpiece hole, and the perpendicularity of the bearing outer ring to the workpiece hole is strictly controlled to prevent bearing scratches or jamming caused by impact or misalignment, thereby improving the working efficiency of the equipment. The positioning mechanism includes a positioning plate, with clamping plates fixedly connected to its front and rear sides. C-shaped plates are fixedly connected to the front and rear sides of the fixed plate. A movable plate is slidably connected to the inner wall of the C-shaped plate via a spring. The movable plate moves along the movement trajectory of the clamping plates. The circumferential surface of the pulley contacts the inner wall of the guide plate. The positioning plate moves along the movement trajectory of the fixed plate. Simultaneously with positioning, the positioning plate moves, causing the movable plate to cooperate with the clamping plates to prevent offset during positioning and avoid offset during tightening. This ensures that the coaxiality and relative position of key components such as bearings and bolts remain within the design tolerance range, preventing accidental detachment or failure of key components during operation, avoiding safety accidents caused by loosening, and improving the service life of the equipment.

[0007] Preferably, the anti-clogging mechanism includes a lubrication box, the right side of which is fixedly connected to the left side of the needle insertion device. A pressure rod is slidably connected to the inner wall of the lubrication box via a spring. A baffle is fixedly connected to the top of the pressure rod. An oil outlet is opened on the inner wall of the baffle, and the baffle is slidably connected to the inner wall of the lubrication box. An oil outlet pipe is fixedly connected to the inner wall of the lubrication box. During positioning, the positioning plate drives the baffle to open the oil outlet, so that the lubricating oil is delivered to the inside of the device through the oil outlet pipe. When the positioning device is working, the lubrication box will lubricate the needle insertion point to prevent direct contact and increase friction, thereby significantly reducing the coefficient of friction and greatly reducing the pushing force required for needle insertion. This avoids scratches or jamming caused by impact or excessive pressure, reduces the generation of fatigue cracks, and thus significantly improves the service life and reliability of the bearing. The anti-clogging mechanism includes a rack, the right side of which is fixedly connected to the left side of the positioning plate. A ring is fixedly connected to the left side of the positioning plate, and a toothed ring is rotatably connected to the inner wall of the ring. A grinding ring is fixedly connected to the inner wall of the toothed ring, and the circumferential surface of the toothed ring meshes with the rack. The circumferential surface of the oil outlet pipe is fixedly connected to the inner wall of the positioning plate. The grinding ring contacts the inner wall of the ring, and the right side of the rack contacts the left side of the positioning plate. Before and after processing, the positioning plate moves, causing the grinding ring to rotate and grind the burrs on the processed bearing. Burrs can cause dimensional deviations and assembly jamming. Deburring ensures the correct fit of parts in subsequent assembly processes, reduces assembly errors and rework rates, significantly reduces the risk of crack formation, improves the fatigue strength and service life of parts, and also significantly improves assembly accuracy and extends service life.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This dual-station bearing needle loading mechanism, through the coordinated operation of a worktable, electric slide plate, step, electric push plate, needle insertion device, motor, cylinder group, T-shaped plate, needle pusher, needle loading table, cylinder, fixed sleeve, annular plate, pressing rod, and clamping plate, enables needle loading. When the operator moves the bushing to the front of the mechanism, the cylinder group is activated, causing the bearing to contact the needle pusher and loading the needle into the bushing. Continuous operation reduces manual intervention intervals, adapts to assembly line rhythms, meets the needs of mass production, and allows for quick switching of needle loading parameters for different bearing models without significant modifications to the mechanical structure, further improving the needle loading efficiency of the equipment. During needle loading, the T-shaped plate drives the clamping plate to rotate and contact the bearing bushing, thereby further fixing it and preventing the bearing bushing from tilting or shifting due to manual pressing. This ensures the coaxiality and positional accuracy requirements of subsequent processes such as needle loading and pressing, reduces the skill requirements of operators, minimizes human error, and significantly improves the accuracy of needle loading.

[0009] 2. This dual-station bearing needle loading mechanism, through the coordinated operation of an L-shaped rod, pulley, guide plate, positioning plate, and fixing plate, simultaneously performs the loading process. The step drives the positioning plate to move downwards, working with the fixing plate to assist in positioning the bearing sleeve. This ensures that the spacing, angle, and depth of the needle body within the bearing sleeve raceway are consistent, improving positioning accuracy and achieving zero-clearance positioning between the bearing and the workpiece inner hole. This ensures that the bearing does not shift when entering the workpiece hole, and the perpendicularity of the bearing outer ring to the workpiece hole is strictly controlled, preventing bearing scratches or jamming due to impact or misalignment, thus improving the equipment's working efficiency.

[0010] 3. This dual-station bearing pin-loading mechanism, through the coordinated operation of the clamping plate, C-shaped plate, and moving plate, achieves positioning while the positioning plate moves to drive the moving plate to cooperate with the clamping plate to prevent displacement during positioning and avoid displacement during tightening. This ensures that the coaxiality and relative position of key components such as bearings and bolts are kept within the design tolerance range, preventing key components from accidentally falling off or failing during operation, avoiding safety accidents caused by loosening, and improving the service life of the equipment.

[0011] 4. This dual-station bearing pin loading mechanism, through the coordinated operation of the lubrication box, pressure rod, baffle, and oil outlet pipe, simultaneously performs positioning. The positioning plate drives the baffle to open the oil outlet hole, thereby delivering lubricating oil into the equipment through the oil outlet pipe. When the positioning device is in operation, the lubrication box will lubricate the pin loading area to prevent direct contact and increase friction, thus significantly reducing the coefficient of friction. The pushing force required for pin loading is greatly reduced, avoiding scratches or jamming caused by impact or excessive pressure, reducing the generation of fatigue cracks, and thus significantly improving the service life and reliability of the bearing.

[0012] 5. This dual-station bearing pin-loading mechanism, through the coordinated operation of the rack, ring, gear ring, and grinding ring, before and after processing, the positioning plate moves to drive the grinding ring to grind the burrs on the processed bearing. Burrs can cause dimensional deviations and assembly jamming. Deburring can ensure the correct fit of parts in subsequent assembly processes, reduce assembly errors and rework rates, significantly reduce the risk of crack formation, improve the fatigue strength and service life of parts, and also significantly improve assembly accuracy and extend service life.

[0015] 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.

[0016] Please see Figures 1-8One embodiment of the present invention is as follows: a dual-position bearing needle loading mechanism, including a worktable 1, an electric slide plate 2 installed on the top of the worktable 1, a step 3 fixedly connected to the top of the electric slide plate 2, a needle pusher 11 installed on the inner wall of the step 3, an electric push plate 4 fixedly connected to the top of the step 3, a motor 6 fixedly connected to the top of the electric slide plate 2, a cylinder group 9 fixedly connected to the output end of the motor 6, a T-shaped plate 10 fixedly connected to the output end of the motor 6, a needle loading platform 12 fixedly connected to the top of the worktable 1, a needle insertion device 5 fixedly connected to the top of the needle loading platform 12, the circumferential surface of the needle pusher 11 contacting the inner wall of the needle loading platform 12, anti-loosening positioning mechanisms 7 provided on the front and rear sides of the needle loading platform 12, and an anti-blocking mechanism 8 to prevent jamming provided on the left side of the needle loading platform 12; During needle loading, the staff first moves the bushing to the front of the mechanism. At this time, the cylinder group 9 is started to drive the bearing to contact and install with the needle pusher cylinder 11. Then the motor 6 starts and controls the cylinder group 9 to rotate 180 degrees. After the rotation is completed, the cylinder group 9 retracts and the second cylinder in the cylinder group 9 pushes out. At the same time as the second cylinder pushes out, the needle plate above is vibrated by the vibrator and continues to drop needles. Through the reciprocating motion of the motor 6, the needle roller is evenly spread around the needle loading center axis during the needle dropping. Then the third cylinder in the cylinder group 9 pushes out and loads the needle roller into the bushing. Continuous operation reduces the interval of manual intervention, can be adapted to the production line cycle, meets the needs of mass production, and can quickly switch the needle loading parameters of different bearing models without major modification of the mechanical structure, further improving the needle loading efficiency of the equipment. The workbench 1 includes a T-shaped plate 10, an annular plate 15 is slidably connected to the inner wall of the T-shaped plate 10 by a spring, a clamping plate 17 is rotatably connected to the inner wall of the annular plate 15 by a torsion spring, a cylinder 13 is rotatably connected to the inner wall of the clamping plate 17, a mortise rod 16 is fixedly connected to the right side of the annular plate 15, and a fixing sleeve 14 is fixedly connected to the right side of the T-shaped plate 10; the output end of the electric push plate 4 is fixedly connected to the circumferential surface of the push needle cylinder 11, and the circumferential surface of the cylinder 13 contacts the inclined surface of the T-shaped plate 10; When cylinder assembly 9 moves T-shaped plate 10 to insert needles via its output end, T-shaped plate 10 moves fixed sleeve 14, which in turn moves bearing sleeve. Simultaneously, fixed sleeve 14 contacts needle pusher cylinder 11, and pressure rod 16 moves backward. Pressure rod 16 moves annular plate 15, which in turn moves clamping plate 17. Clamping plate 17 moves cylinder 13. Cylinder 13 then contacts the inclined surface of T-shaped plate 10 via its circumferential surface. The torsion spring between cylinder 13 and annular plate 15 causes clamping plate 17 to rotate. This rotation brings clamping plate 17 into contact with bearing sleeve for further fixation. This prevents bearing sleeve tilting or displacement caused by manual pressing, ensuring coaxiality and positional accuracy in subsequent processes such as needle insertion and pressing. It also reduces the skill requirements of operators, minimizes human error, and significantly improves needle insertion accuracy.

[0017] Working principle: During needle loading, the operator first moves the bushing to the front of the mechanism. At this time, the cylinder group 9 is activated, and the bearing contacts the needle pusher cylinder 11 to load the needle into the bushing. Continuous operation reduces the interval of manual intervention, adapts to the production line cycle, meets the needs of mass production, and can quickly switch the needle loading parameters of different bearing models without major modification to the mechanical structure, further improving the needle loading efficiency of the equipment. During needle loading, the T-shaped plate 10 drives the clamping plate 17 to rotate and contact the bearing sleeve, thereby further fixing it and avoiding the bearing sleeve tilting or displacement caused by manual pressing. This ensures the coaxiality and positional accuracy requirements of subsequent processes such as needle loading and pressing, reduces the skill requirements of operators, reduces human error, and greatly improves the accuracy of needle loading.

[0018] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the positioning mechanism 7 includes an L-shaped rod 71, which is fixedly connected to both sides of the output end of the step 3. A pulley 72 is installed on the side of the L-shaped rod 71 away from the step 3. A fixing plate 75 is fixedly connected to the left side of the needle loading table 12. A positioning plate 74 is slidably connected to the left side of the needle loading table 12. Guide plates 73 are fixedly connected to the front and rear sides of the positioning plate 74. The guide plates 73 are in contact with the front and rear sides of the needle loading table 12. While the device is in operation, the movement of step 3 will drive the L-shaped rod 71 to move through the output end. The L-shaped rod 71 will drive the pulley 72 to move. The movement of pulley 72 will cause it to contact the inner wall of guide plate 73 through its circumferential surface, thereby driving guide plate 73 to move downward. Guide plate 73 will drive positioning plate 74 to move downward. The downward movement of positioning plate 74 will cooperate with fixing plate 75 to assist in positioning the bearing sleeve, ensuring that the spacing, angle and depth of the needle body in the bearing sleeve raceway are consistent, improving positioning accuracy, realizing zero-gap positioning between the bearing and the inner hole of the workpiece, ensuring that the bearing does not deviate when entering the workpiece hole, and strictly controlling the perpendicularity between the outer ring of the bearing and the workpiece hole, preventing bearing scratches or jamming caused by impact or misalignment, and improving the working efficiency of the equipment. The positioning mechanism 7 includes a positioning plate 74, with locking plates 76 fixedly connected to the front and rear sides of the positioning plate 74, and C-shaped plates 77 fixedly connected to the front and rear sides of the fixed plate 75. A movable plate 78 is slidably connected to the inner wall of the C-shaped plate 77 via a spring. The movable plate 78 moves along the movement trajectory of the locking plate 76, the circumferential surface of the pulley 72 contacts the inner wall of the guide plate 73, and the positioning plate 74 moves along the movement trajectory of the fixed plate 75. During positioning, the positioning plate 74 moves, causing the clamping plate 76 to move. The clamping plate 76 moves and contacts the moving plate 78 through the inclined surface, thereby causing the moving plate 78 to move. When the clamping plate 76 enters the middle of the C-shaped plate 77, the moving plate 78 will be reset by the spring between it and the C-shaped plate 77. Thus, the moving plate 78 cooperates with the clamping plate 76 to prevent the positioning plate 74 from shifting during positioning, avoiding shifting during the fastening process. This ensures that the coaxiality and relative position of key components such as bearings and bolts are kept within the design tolerance range, preventing key components from accidentally falling off or failing during operation, avoiding safety accidents caused by loosening, and improving the service life of the equipment.

[0019] Working principle: During device operation, step 3 moves the positioning plate 74 downwards, which, together with the fixing plate 75, assists in positioning the bearing sleeve. This ensures that the spacing, angle, and depth of the needle body within the bearing sleeve raceway are consistent, improving positioning accuracy and achieving zero-clearance positioning between the bearing and the workpiece inner hole. This ensures that the bearing does not shift when entering the workpiece hole, and the perpendicularity of the bearing outer ring to the workpiece hole is strictly controlled, preventing bearing scratches or jamming due to impact or misalignment, thus improving the equipment's working efficiency. Simultaneously, the positioning plate 74 moves, driving the moving plate 78 to cooperate with the clamping plate 76 to prevent shifting during positioning and avoid shifting during tightening. This ensures that the coaxiality and relative position of key components such as bearings and bolts remain within the design tolerance range, preventing key components from accidentally falling off or failing during operation, avoiding safety accidents caused by loosening, and improving the service life of the equipment.

[0020] The anti-clogging mechanism 8 includes a lubrication box 81. The right side of the lubrication box 81 is fixedly connected to the left side of the needle device 5. The inner wall of the lubrication box 81 is slidably connected to a pressure rod 82 by a spring. The top of the pressure rod 82 is fixedly connected to a baffle 83. The inner wall of the baffle 83 is provided with an oil outlet, and the baffle 83 is slidably connected to the inner wall of the lubrication box 81. The inner wall of the lubrication box 81 is fixedly connected to an oil outlet pipe 84. During positioning, the positioning plate 74 moves upward and contacts the bottom of the pressure rod 82 through its top, thereby driving the pressure rod 82 to move. The pressure rod 82 drives the baffle 83 to move, and the movement of the baffle 83 closes the oil outlet. When the positioning plate 74 moves downward and is positioned, the pressure rod 82 is reset by the spring between it and the lubrication box 81, thereby resetting the baffle 83 and opening the oil outlet. Thus, the lubricating oil is delivered to the inside of the equipment through the oil outlet pipe 84. When the positioning device is in operation, the lubrication box 81 will lubricate the needle insertion point to prevent direct contact and increase friction, thereby significantly reducing the coefficient of friction. The pushing force required for needle insertion is greatly reduced, avoiding scratches or jamming caused by impact or excessive pressure, reducing the generation of fatigue cracks, and thus significantly improving the service life and reliability of the bearing. The anti-clogging mechanism 8 includes a rack 85, the right side of which is fixedly connected to the left side of the positioning plate 74. A ring 86 is fixedly connected to the left side of the positioning plate 75. A toothed ring 87 is rotatably connected to the inner wall of the ring 86. A grinding ring 88 is fixedly connected to the inner wall of the toothed ring 87. The circumferential surface of the toothed ring 87 meshes with the rack 85. The circumferential surface of the oil outlet pipe 84 is fixedly connected to the inner wall of the positioning plate 74. The grinding ring 88 contacts the inner wall of the ring 86. The right side of the rack 85 contacts the left side of the positioning plate 75. Before and after processing, the positioning plate 74 moves, driving the rack 85 to move. The rack 85 moves and meshes with the gear ring 87, thereby driving the gear ring 87 to rotate. The rotation of the gear ring 87 drives the grinding ring 88 to rotate. The rotation of the grinding ring 88 grinds the burrs on the processed bearing. Burrs can cause dimensional deviations and assembly jamming. Deburring can ensure the correct fit of parts in subsequent assembly processes, reduce assembly errors and rework rates, significantly reduce the risk of crack formation, improve the fatigue strength and service life of parts, and significantly improve assembly accuracy and extend service life.

When the positioning device is in operation, the lubrication box 81 will lubricate the needle insertion point to prevent direct contact and increase friction, thus significantly reducing the coefficient of friction.
