Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.
[0025] As Figures 1-5 shown, the present utility model provides a technical solution: a gear deburring device, which includes a base 1, a workpiece 2 and a limiting plate 3. A support plate 4 is fixedly connected to the top end of the base 1. Several tooth grooves are formed on the surface of the support plate 4. The workpieces 2 are distributed in a linear array. The workpieces 2 are movably connected to the top end of the support plate 4 by being engaged with the tooth grooves. The limiting plates 3 are symmetrically arranged, and several tooth grooves are formed on the opposite sides of the limiting plates 3. The workpieces 2 are all located on the opposite sides of the limiting plates 3. A driving mechanism 5 is arranged outside the base 1, and the driving mechanism 5 is fixedly connected to the back side of the limiting plate 3. A grinding mechanism 6 is fixedly connected to the top end of the support plate 4, and the grinding mechanism 6 is movably connected to the inner ring of the workpiece 2.
[0026] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the driving mechanism 5 includes support columns 501, connecting rods 502, auxiliary plates 503, driving rods 504 and sliders 505. The auxiliary plates 503, support columns 501 and connecting rods 502 are a total of two groups, and each group of connecting rods 502 is symmetrically arranged. The sliders 505 are symmetrically arranged. One end of each connecting rod 502 is movably connected to the side of the slider 505 through a rotating shaft, and the other end of the connecting rod 502 is movably connected to the side of the support column 501 through a rotating shaft. The auxiliary plate 503 is fixedly connected to the side of the base 1, and the bottom end of the support column 501 is movably connected to the top end of the auxiliary plate 503. A set of symmetric threads are formed on the outside of the driving rod 504. The driving rod 504 penetrates through the slider 505, and the driving rod 504 is threadedly connected to the slider 505. The top ends of the support columns 501 are respectively fixedly connected to the back side of the limiting plate 3. The driving rod 504 is movably connected to the inside of the base 1 through a bearing. The sliders 505 are all movably connected to the inside of the base 1. The driving mechanism 5 further includes a servo motor 506. The servo motor 506 is fixedly connected to the outside of the base 1, and the output end of the servo motor 506 is fixedly connected to one end of the driving rod 504.
[0027] Start the servo motor 1 506 to drive the drive rod 504 to rotate inside the base 1. Since the drive rod 504 is threadedly connected to the slider 505, the sliders 505 move away from each other, driving the connecting rods 502 on both sides of the sliders 505 to rotate, successively pulling the two support columns 501 to approach each other along the auxiliary plate 503, driving the two limit plates 3 to approach each other. Since a plurality of tooth grooves are provided on the inner sides of the limit plates 3, and the tooth grooves are engaged with the teeth of the workpiece 2, it is convenient to use the limit plates 3 to uniformly clamp the workpiece 2, so that all workpieces 2 to be polished can be kept stable at the same time.
[0028] As Figure 1 , Figure 2 , Figure 3 and Figure 5 shown, the grinding mechanism 6 includes a grinding plate 601, a mounting post 602, an adjusting rod 603 and a moving ring 604. The adjusting rods 603 and the moving rings 604 are both symmetrically arranged. One end of each adjusting rod 603 is movably connected to the inner side of the grinding plate 601 through a rotating shaft, and the other end of each adjusting rod 603 is movably connected to the outer side of the moving ring 604 through a rotating shaft. The mounting post 602 penetrates through the moving ring 604, and the mounting post 602 is movably connected to the moving ring 604. The outer side of the grinding plate 601 is movably connected to the inner side wall of the workpiece 2. The grinding mechanism 6 further includes a control rod 605 and a knob 606. The control rod 605 is movably connected to the inside of the mounting post 602, and one end of the control rod 605 extends to the outside of the mounting post 602, and the knob 606 is fixedly connected to one end of the control rod 605. A set of symmetric threads is provided on the outer side of the control rod 605. The control rod 605 penetrates through the moving ring 604, and the control rod 605 is threadedly connected to the moving ring 604. The grinding mechanism 6 further includes a servo motor 2 607 and a support block 608. The bottom end of the support block 608 is fixedly connected to the top end of the support plate 4. One end of the mounting post 602 penetrates through the support block 608, and the mounting post 602 is movably connected to the support block 608 through a bearing. The servo motor 2 607 is fixedly connected to the top end of the support plate 4, and the output end of the servo motor 2 607 is fixedly connected to one end of the mounting post 602.
[0029] Rotate the knob 606 to drive the control rod 605 to rotate inside the mounting post 602. Since the control rod 605 is threadedly connected to the moving ring 604 and the mounting post 602 restricts the position of the moving ring 604, the moving rings 604 approach each other, driving the adjusting rods 603 to rotate until the outer side of the grinding plate 601 fits against the inner side wall of the workpiece 2. Then start the servo motor 2 607 to drive the mounting post 602 to rotate, so that the grinding plate 601 rotates around the mounting post 602. By the friction between the outer side of the grinding plate 601 and the inner side wall of the workpiece 2, the inner walls of all workpieces 2 are uniformly ground, improving the grinding efficiency of the workpiece 2 and facilitating the grinding of multiple workpieces 2 at one time.
[0030] Working principle: When in use, first, the grinding plate 601 is in a contracted state, that is, the grinding plate 601 is close to the outer side of the mounting post 602. Subsequently, the workpiece 2 is passed through the mounting post 602 and the grinding plate 601, and the workpiece 2 is moved until it is stuck in the tooth grooves at the top of the pallet 4. By operating in sequence to insert other workpieces 2 into the tooth grooves at the top of the pallet 4, the workpiece 2 can be kept in a vertical state. Then, the servo motor 506 is started to drive the driving rod 504 to rotate inside the base 1. Since the driving rod 504 is threadedly connected to the slider 505, the sliders 505 move away from each other, driving the connecting rods 502 on both sides of the slider 505 to rotate, and sequentially pulling the two support columns 501 to approach each other along the auxiliary plate 503, driving the two limit plates 3 to approach each other. Since several tooth grooves are formed on the inner sides of the limit plates 3, by matching the tooth grooves with the teeth of the workpiece 2, the workpiece 2 is uniformly clamped by the limit plates 3. Then, by rotating the knob 606, the control rod 605 is driven to rotate inside the mounting post 602. Since the control rod 605 is threadedly connected to the moving ring 604 and the mounting post 602 restricts the position of the moving ring 604, the moving rings 604 approach each other, driving the adjusting rod 603 to rotate until the outer side of the grinding plate 601 fits against the inner side wall of the workpiece 2. Then, the servo motor 607 is started to drive the mounting post 602 to rotate, causing the grinding plate 601 to rotate around the mounting post 602. By the friction between the outer side of the grinding plate 601 and the inner side wall of the workpiece 2, the burrs on the inner side wall of the workpiece 2 are removed.
