[0027] Example:
[0028] like Figure 1-5As shown in this embodiment, a burr removal device for gear forgings after machining, which is easy to clamp, includes a base 1. Several uprights 2 arranged at equal angles around the circumference are fixedly connected to the top of the base 1. A worktable 3 is fixedly connected to the top of the uprights 2. The gear to be processed is placed on the center of the upper surface of the worktable 3. Four guide slots 4 arranged at equal angles around the circumference are provided through the worktable 3. An electric push rod 5 is fixedly connected to the center of the top of the base 1. A connecting plate 6 is fixedly connected to the push rod end of the electric push rod 5. Activating the electric push rod 5 causes the connecting plate 6 to move upwards. Four mounting slots 7 arranged at equal angles around the circumference are provided through the side of the connecting plate 6. Rotary wheels 8 are rotatably connected within the mounting slots 7. The four rotating wheels 8 move upwards synchronously with the connecting plate 6. An L-shaped slider 9 is slidably connected within the guide slots 4. A trapezoidal connecting block 10 is fixedly connected to the bottom of the L-shaped slider 9. The four rotating wheels... The outer surfaces of the four wheels 8 abut against the inclined surfaces of the four trapezoidal connecting blocks 10. As the four wheels 8 move upward, they cooperate with the inclined surfaces of the four trapezoidal connecting blocks 10, causing the four trapezoidal connecting blocks 10 to move away from each other. The top of the L-shaped slider 9 is fixedly connected to a fixing rod 11. The four fixing rods 11 are arranged in a circle at equal angles around the center of the worktable 3. The inner wall of the guide groove 4 is fixedly connected to the L-shaped slider 9. The four L-shaped sliders 9 move synchronously with the four trapezoidal connecting blocks 10. The four L-shaped sliders 9 slide in the four guide grooves 4. The four tension springs 12 are stretched and deformed by force. Through the cooperation of the four trapezoidal connecting blocks 10 and the four L-shaped sliders 9, the four fixing rods 11 move away from each other. Finally, the outer surfaces of the four fixing rods 11 abut against the inner surfaces of the mounting holes on the gear, achieving the centering and positioning of the gear.
[0029] like Figure 1 , Figure 4 and Figure 5As shown, a bracket 13 is fixedly installed on the top of the workbench 3. A cylinder 14 is fixedly installed at the center of the upper inner surface of the bracket 13. A connecting frame 15 is fixedly connected to the push rod end of the cylinder 14. A drive motor 16 is fixedly installed on the inner surface of the connecting frame 15. A connecting shaft 17 is fixedly connected to the output end of the drive motor 16. A fixing block 18 is fixedly connected to the end of the connecting shaft 17 away from the drive motor 16. A slot 19 is opened on the lower surface of the fixing block 18. A locking block 20 is inserted into the slot 19. A disc brush 21 is fixedly installed on the lower surface of the locking block 20. The disc brush 21 is located directly above the center of the workbench 3. The locking block 20 is fixed by fastening bolts 22. The disc brush 21 is fixedly installed in the slot 19. After the gear is positioned, the cylinder 14 drives the connecting frame 15 to move down, so that the bristles on the disc brush 21 are in contact with the outer surface of the gear. Then the drive motor 16 is started, and the fixed block 18 and the disc brush 21 are rotated through the connecting shaft 17. The rotating disc brush 21 cleans the burrs on the surface of the gear. When the disc brush 21 needs to be cleaned later, the fastening bolt 22 is tightened with the appropriate tool to remove it from the fixed block 18. Then the disc brush 21 is pulled down to disengage the card block 20 from the slot 19 and the disc brush 21 is removed for subsequent cleaning.
[0030] like Figure 1 and Figure 4 As shown, two guide rods 23 are fixedly connected to the upper surface of the connecting frame 15, which are symmetrically distributed about the central axis of the cylinder 14. The guide rods 23 movably pass through the bracket 13. The two guide rods 23 can provide auxiliary guidance for the connecting frame 15 and ensure the stability of the connecting frame 15 during vertical movement.
[0031] The working principle of the above embodiment is as follows: The electric push rod 5 and the drive motor 16 are electrically connected to an external control power supply. First, the gear to be processed is placed in the center of the upper surface of the workbench 3, with the four fixed rods 11 positioned inside the mounting holes on the gear. Then, the electric push rod 5 is activated, causing the connecting plate 6 to move upwards. The four rotating wheels 8 move upwards synchronously with the connecting plate 6. During the upward movement of the four rotating wheels 8, they engage with the inclined surfaces on the four trapezoidal connecting blocks 10, causing the four trapezoidal connecting blocks 10 to move away from each other. The four L-shaped sliders 9 move synchronously with the four trapezoidal connecting blocks 10, and the four L-shaped sliders 9 are respectively positioned in the four guide channels. The gear slides within the groove 4, and the four tension springs 12 are stretched and deformed. Through the cooperation of the four trapezoidal connecting blocks 10 and the four L-shaped sliders 9, the four fixed rods 11 are moved away from each other. Finally, the outer surfaces of the four fixed rods 11 abut against the inner surfaces of the mounting holes on the gear, achieving the centering and positioning of the gear. At the same time, it can adapt to gears with different inner diameters, making it more widely applicable. After the gear is positioned, the cylinder 14 drives the connecting frame 15 to move down, so that the bristles on the disc brush 21 are in contact with the outer surface of the gear. Then, the drive motor 16 is started, and the fixed block 18 and the disc brush 21 are rotated through the connecting shaft 17. The rotating disc brush 21 cleans the burrs on the surface of the gear.

Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
