[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] A bearing assembly riveting device, such as Figures 1-4 As shown, the system includes a mounting plate 1. A cylinder 2 is fixedly connected to the lower end of the mounting plate 1. The output end of the cylinder 2 faces upward and passes through the mounting plate 1. A positioning mechanism for positioning the inner hole of the bearing is fixedly connected to the output end of the cylinder 2. Multiple sets of guide shafts 10 are fixedly connected to the mounting plate 1. The multiple sets of guide shafts 10 are perpendicular to the mounting plate 1 and parallel to each other. A push plate 9 is slidably connected to the multiple sets of guide shafts 10. Multiple sets of round steel bars 18 are fixedly connected between the positioning mechanism and the push plate 9. A bearing seat 11 is fixedly connected to the upper end of the push plate 9. A mounting base 16 is fixedly connected to the upper end of the multiple sets of guide shafts 10. A sensing mechanism is fixedly connected to the upper end of the mounting base 16. An elastic pressing mechanism is fixedly connected to the lower end of the mounting base 16. The elastic pressing mechanism cooperates with the bearing seat 11 and the sensing mechanism.
[0024] By connecting and installing the bearing body 20 and the iron housing 21 onto the bearing seat 11, the bearing body 20 and the iron housing 21 are positioned below the elastic pressing mechanism. The positioning mechanism positions the bearing inner hole. Cylinder 1 2 (model AT91-100-2223) controls the lifting of the positioning mechanism. The round steel 18 pushes the push plate 2 9 to slide on multiple sets of guide shafts 10, causing the bearing body 20 and the iron housing 21 to be lifted and pressed against the elastic pressing mechanism, thereby riveting the bearing into the iron housing 21. The elastic pressing mechanism is compressed, triggering the sensing mechanism. The elastic pressing mechanism can buffer the riveting process and prevent excessive impact from damaging the parts. The sensing mechanism can be triggered after the riveting is completed, promptly reminding that the riveting process is over. The bearing riveting effect is good.
[0025] like Figure 1 , Figure 2 , Figure 4As shown, the elastic pressing mechanism includes a positioning seat 15, which is fixed to the lower end of the mounting seat 16. A limit post 22 and a spring 13 are fixed to the lower end of the positioning seat 15. The limit post 22 is located inside the spring 13. A pressure motor seat 12 is fixed to the lower end of the spring 13. The lower end of the pressure motor seat 12 is pressed against the upper end of the bearing seat 11.
[0026] When the push plate 29 is raised, the bearing seat 11 and the bearing body 20 are raised, pressing the motor seat 12 and compressing the spring 13. The spring 13 plays a certain buffering role, and the motor seat 12 and the bearing seat 11 rivet the bearing plate and the iron housing 21.
[0027] like Figure 1 , Figure 2 , Figure 4 As shown, a push pin 14 is slidably connected inside the limiting post 22. The push pin 14 passes through the positioning seat 15. A hole 8 is opened on the mounting seat 16. The upper end of the push pin 14 is inserted into the hole 8, and the lower end of the push pin 14 is located inside the pressure motor seat 12.
[0028] When the push plate 29 is raised to a certain extent, the iron housing 21 presses the motor seat 12, the spring 13 is compressed, the motor seat 12 and the positioning seat 15 are close together, the push needle 14 is exposed, the upper end of the iron housing 21 presses the lower end of the push needle 14, causing the push needle 14 to slide, and the upper end is exposed from the hole 8.
[0029] like Figures 1-4 As shown, the sensing mechanism includes a sensor 17, which is fixed to the upper end of the mounting base 16. The sensing port of the sensor 17 is directly opposite the hole 8. The sensor 17 is used to sense the lifting status of the push pin 14.
[0030] The sensing path of sensor 17 passes over the hole 8. When the riveting is completed, the upper end of push pin 14 will be exposed in the hole 8. Sensor 17 senses push pin 14, and the riveting process is completed.
[0031] Sensor 17 is existing technology and can be an infrared sensor or an ultrasonic sensor.
[0032] like Figures 1-2 As shown, the positioning mechanism includes a push base 3, which is fixedly connected to the output end of cylinder 2. A push plate 4 is fixedly connected to the upper end of the push base 3, and a cylinder 5 is fixedly connected to the upper end of the push plate 4. Cylinder 5 is located between multiple sets of round steel bars 18. A push shaft 6 is fixedly connected to the output end of cylinder 5. A tungsten steel needle 7 is fixedly connected inside the push shaft 6. The end of the tungsten steel needle 7 passes through the push shaft 6. The push shaft 6 is inserted into the bearing seat 11, and the end of the tungsten steel needle 7 is inserted into the upper end of the bearing seat 11.
[0033] The output end of cylinder 2 drives the pusher 3 to rise, the pusher 3 drives the pusher plate 4 to rise, the pusher plate 4 supports the positioning mechanism, so that the positioning mechanism is raised. Before riveting, the output end of cylinder 5 extends, the push shaft 6 is located in the bearing seat 11, and the upper end of the tungsten steel needle 7 penetrates the upper end of the bearing seat 11, so that the bearing body 20 can be installed on the bearing seat 11. After riveting, the tungsten steel needle 7 enters the bearing seat 11.
[0034] like Figure 4 As shown, the limiting post 22 is shaped as a regular hexagonal prism, and the limiting post 22 is fitted and inserted into the inner wall of the pressure motor seat 12.
[0035] The shapes of the limiting post 22 and the pressure motor seat 12 prevent them from rotating after being inserted, thereby preventing the pressure motor seat 12 from causing the iron housing 21 to rotate and deviate due to friction.
[0036] The working principle of the bearing assembly riveting device provided by this utility model is as follows:
[0037] By connecting and installing the bearing body 20 and the iron housing 21 onto the bearing seat 11, cylinder 2 5 drives the push shaft 6 and tungsten steel needle 7 to extend and position the bearing inner hole. Cylinder 1 2 controls the positioning mechanism to lift, and push plate 2 9 is pushed by round steel 18 to slide on multiple sets of guide shafts 10, so that the bearing body 20 and the iron housing 21 are lifted and pressed against the pressure motor seat 12, thereby riveting and assembling the bearing into the iron housing 21. Spring 13 is compressed, and the upper end of push needle 14 passes through hole 8, triggering sensor 17. The elastic pressing mechanism can buffer the riveting process to prevent excessive impact from damaging the parts. The sensing mechanism can be triggered after riveting is completed to promptly remind that the riveting process is over.
[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
