Description
Technical Field
[0001] This utility model relates to the field of bearing production technology, specifically to a bearing production and processing table for electric tricycles. Background Technology
[0002] Three-wheeled vehicle bearings are crucial components in three-wheeled vehicles, supporting the wheels and enabling their smooth rotation. A bearing production processing table refers to a hardware system comprised of various equipment, tooling fixtures, and other components used in bearing production. It is a specialized equipment platform for precision machining, positioning, clamping, and surface treatment of workpieces during the bearing manufacturing process. Its core function is to achieve efficient and stable processing at each stage of bearing production through mechanical structures, automated components, and auxiliary devices. Early processing tables had relatively simple structures and lacked precise transfer mechanisms. Workers often had to manually place the bearing workpieces into the processing position. This method was not only inefficient, but the positioning accuracy also relied entirely on the worker's experience and skill, making it difficult to guarantee accurate placement every time. Regarding workpiece clamping, previous clamping devices had simple structures and unstable clamping force, easily leading to workpiece drops during transfer. Once a workpiece falls, it can damage the workpiece, cause equipment malfunctions, and affect production progress. Furthermore, simple clamping devices were poorly adaptable to bearings of different sizes and shapes, requiring frequent replacement of clamping components, increasing production costs and operational complexity. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] Example: Figure 1-3As shown, this utility model provides a production and processing table for electric tricycle bearings, including a workbench 11. A gantry frame 12 is fixedly installed on one side of the workbench 11. A drive motor 13 is fixedly installed on the side of the gantry frame 12 facing away from the workbench 11. The output end of the drive motor 13 passes through the gantry frame 12 and is fixedly sleeved with a first connecting rod 14. One end of the first connecting rod 14 is rotatably connected to a second connecting rod 15. A conveyor belt is fixedly installed on one side of the upper surface of the workbench 11, and a rotary chuck 18 is fixedly installed on the other side of the upper surface of the workbench 11. A grinding machine 17 is fixedly installed on the side of the workbench 11 near the rotary chuck 18. The conveyor belt is used to transport workpieces such as electric tricycle bearings to be processed to a suitable processing position. The rotary chuck 18 is used to fix and rotate the workpieces, facilitating the grinding machine 17 to process them. The grinding machine 17 performs grinding and other processing operations on the workpieces. The three work together to complete the conveying, fixing and processing process of the workpieces. A first slide rail 19 is fixedly installed on one side of the gantry frame 12. A first slider 20 is slidably connected to the outer surface of the first slide rail 19. A first connecting plate 21 is fixedly connected to one side of the first slider 20. One side of the second connecting rod 15 is slidably connected to the first connecting plate 21. A second slide rail 23 is fixedly installed on the side of the second connecting rod 15 facing the gantry frame 12. A second slider 22 is slidably sleeved on the outer surface of the second slide rail 23. One side of the second slider 22 is fixedly connected to the first connecting plate 21. Its function is to allow the first connecting plate 21 to slide on the second slide rail 23 when the second connecting rod 15 moves, thus assisting... The guide and fine-tuning position enhances the flexibility and stability of the motion mechanism, facilitating precise control of component positions and motion trajectories. A clamping device 16 is fixedly installed on one side of the lower end of the second connecting rod 15. When the drive motor 13 starts, the output shaft rotates, driving the first connecting rod 14 to make a circular motion. The movement of the second connecting rod 15 drives the first slider 20 to slide on the first slide rail 19, realizing horizontal transfer. At the same time, the clamping device 16 fixed on one side of the lower end of the second connecting rod 15 also moves accordingly, and can move to the conveyor belt to grab the electric tricycle bearing workpiece, and then transfer it to the rotary chuck 18 and other processing positions.
[0015] The clamping device 16 includes a back plate 25. A rotary cylinder 24 is fixedly installed on one side of the lower end of the second connecting rod 15. One end of the rotary cylinder 24 is fixedly connected to the back plate 25. Its function is to drive the back plate 25 and the clamping device 16 and other components mounted on it to rotate through the rotary cylinder 24, thereby adjusting the angle of the clamping device 16 to adapt to different processing requirements and operating positions, and improving the adaptability of the equipment to different working conditions. A linear cylinder 26 is fixedly installed on the upper surface of the back plate 25. A third slide rail 27 and a fourth slide rail 28 are fixedly installed on one side of the back plate 25. The outer surface of the slide rail 31 and the third slide rail 27 is slidably fitted with a third slider 28. A second connecting plate 29 is fixedly installed on one side of the third slider 28. A spring pin is slidably inserted into the lower end of the second connecting plate 29. The lower end of the spring pin is fixedly connected to one side of the back plate 25. The spring pin can buffer the impact force generated when the linear cylinder 26 pushes the third slider 28 to slide on the third slide rail 27, reduce rigid collisions of components, protect the equipment, and at the same time ensure the stability and accuracy of the movement of the third slider 28, making the operation of the clamping device 16 more reliable. The output end of the linear cylinder 26 is fixedly connected to the third slider 28. The outer surface of the fourth slide rail 31 is symmetrically fitted with a fourth slider 32. An L-shaped plate 30 is symmetrically rotatably connected to one side of the third slider 28. Two rotating shafts are symmetrically fixedly installed on one side of the back plate 25, with one end of each shaft rotatably connected to two L-shaped plates 30, providing rotational support points for the L-shaped plates 30. This allows the L-shaped plates 30 to rotate around the rotating shafts. When the linear cylinder 26 pushes the third slider 28, the motion is transmitted to the fourth slider 32 through the rotation of the L-shaped plates 30, realizing the opening and closing action of the gripper 34. The lower ends of the two L-shaped plates 30 are rotatably connected to the two fourth sliders 32. A third connecting plate 33 is fixedly connected to one side of each of the two fourth sliders 32. Each side of the two third connecting plates 33... A gripper 34 is fixedly installed, with one end of the gripper 34 being V-shaped. As a key component of the clamping device 16, the gripper 34 is used to grip and fix workpieces such as electric tricycle bearings. The V-shaped design can better fit the round workpiece, increase the contact area and friction, and improve the clamping stability and reliability. When the rotary cylinder 24 is working, it can drive the back plate 25 and its components to rotate, thereby adjusting the angle of the clamping device 16 to adapt to different processing requirements. When the linear cylinder 26 extends and retracts, it pushes the third slider 28 to slide on the third slide rail 27. The sliding of the third slider 28 is transmitted through the L-shaped plate 30, which drives the fourth slider 32 to slide on the fourth slide rail 31. Therefore, the extension and retraction of the linear cylinder 26 ultimately realizes the opening and closing of the gripper 34, completing the clamping and releasing action of the electric tricycle bearing workpiece.
[0016] Working Principle: The worktable 11 is the basic load-bearing structure of the entire processing table. A conveyor belt is installed on one side of the upper surface of the worktable 11 to transport workpieces such as electric tricycle bearings to the appropriate processing position. A rotary chuck 18 installed on the other side of the upper surface of the worktable 11 can be used to fix and rotate workpieces such as bearings, facilitating subsequent processing operations. A grinder 17 near the rotary chuck 18 is used for grinding and other processing of the bearings. When the drive motor 13 is working, its output shaft drives the first connecting rod 14, which is fixedly sleeved with it, to rotate. Since one end of the first connecting rod 14 is rotatably connected to the second connecting rod 15, the circumferential rotation of the first connecting rod 14 is converted into the complex motion of the second connecting rod 15. A first slide rail 19 is fixedly installed on one side of the gantry frame 12, and a first slider 20 can slide on its outer surface. The first slider 20 is connected to the first connecting plate 21, and the second connecting rod 15 is slidably connected to the first connecting plate 21. When the first connecting rod 14 rotates, it pushes the second connecting rod 15. Because the second connecting rod 15 is connected to the first connecting plate 21, and the first connecting plate 21 is connected to the first slider 20, the movement of the second connecting rod 15 will cause the first slider 20 to slide on the first slide rail 19. During the horizontal transfer process driven by the rotation of the first connecting rod 14, the second connecting rod 15 and the first connecting plate 21 may have relative vertical displacement. At this time, the second slider 22 will slide on the second slide rail 23 to make fine adjustments to the vertical position, thereby realizing the horizontal transfer action. For example, when the first connecting rod 14 rotates clockwise by a certain angle, it will drive the second connecting rod 15 to move to the right, thereby pushing the first slider 20 to slide to the right on the first slide rail 19, moving the clamping device 16 to the specified horizontal position; the lower end of the second connecting rod 15 is connected to the clamping device 16 through the rotary cylinder 24. During the transfer process, when the second connecting rod 15 moves the clamping device 16 above the conveyor belt, the clamping device 16 can control the opening and closing of the gripper 34 via the linear cylinder 26 to grip the electric tricycle bearing workpiece. The linear cylinder 26 is fixedly installed on the upper surface of the back plate 25, and the third slide rail 27 and the fourth slide rail 31 are fixedly installed on one side of the back plate 25. The output end of the linear cylinder 26 is fixedly connected to the third slider 28, which is slidably sleeved on the outer surface of the third slide rail 27. When the linear cylinder 26 is working, it will push the third slider 28 to slide on the third slide rail 27. The third slider 28 is symmetrically rotated and connected to the L-shaped plate 30 on one side, and the fourth slide rail 31 is symmetrically slidably sleeved on the outer surface of the fourth slide rail 31. The lower ends of the two L-shaped plates 30 are rotatably connected to the two fourth slide rails 32 respectively. When the third slider 28 slides, it will drive the fourth slider 32 to slide on the fourth slide rail 31 through the L-shaped plate 30. The opening and closing of the gripper 34 can be controlled by the extension and retraction of the linear cylinder 26 to realize the clamping and releasing operation of the workpiece. Then, the second connecting rod 15 continues to move, transferring the gripped workpiece to the position of the rotary chuck 18, and fixing the workpiece on the rotary chuck 18.Afterwards, the grinding machine 17 can perform grinding and other operations on the workpiece. After the processing is completed, the second connecting rod 15 can transfer the processed workpiece from the rotary chuck 18 and place it on the conveyor belt, thus realizing the entire production and processing process.
