[0002] A gear is a mechanical component with gears on a wheel rim that continuously mesh to transmit motion and power. The use of gears in transmissions dates back to the late 19th century. The principle of gear cutting by generating, along with specialized machine tools and cutting tools that utilize this principle, emerged. With the development of production, the smooth operation of gears has become increasingly important.

[0003] Most of the existing gear tooth profile finishing and polishing processes require manual positioning and tightening, resulting in low work efficiency. Therefore, it is necessary to design a gear tooth profile finishing and polishing device and a method for using the same. Summary of the Invention

The present invention uses a mechanical arm and a mechanical gripper to clamp multiple gears at the same time, and automatically place them on the gear positioning parts, and uses a grinding assembly to finish multiple gears at the same time, thereby effectively improving the efficiency of gear finishing.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a gear tooth profile finishing and grinding device, comprising a first frame, gear positioning members are installed at equal distances on the top of the first frame, a frame is installed around the top of the first frame, grinding components corresponding to the gear positioning members are installed on the frame, a robotic arm is installed on one side of the top of the first frame, a robotic gripper is installed on the top of the robotic arm, a second frame is installed on the front side of the first frame, a conveyor belt is installed on the second frame, a spacing adjustment mechanism is installed on the conveyor belt through a third telescopic cylinder, and an electric control box is installed on one side of the second frame.

[0036] Example 3

[0037] A method for using a gear tooth profile finishing and grinding device comprises the following steps:

[0038] Step 1: The gears are transported by the conveyor belt 3. The counter 12 counts the gears that have passed through. When the number of gears that have passed through matches the number of the gear positioning members 6, the first telescopic cylinder 15 drives the limit baffle 13 to move inside the groove 14 to close the two ends of the conveyor belt 3 until the gears between the limit baffles 13 are close to each other. The conveyor belt 3 stops working and the limit baffle 13 automatically resets.

[0039] Step 2: The third telescopic cylinder 7 works, driving the adjusting head 27 at the bottom end of the spacing adjustment mechanism 8 to press against the gear. Then the second telescopic cylinder 24 works, driving the limit block 26 to move inside the limit rail 25, thereby driving the lifting plate 18 to move upward, and then driving the driving arm 20 to move through the driving slot 19, so that the adjusting rod 23 and the adjusting head 27 drive the gear to adjust the spacing;

[0040] Step 3: After the gear spacing is adjusted, the robotic arm 10 drives the robotic gripper 11 to move, grab the gear after the spacing is adjusted, and place it on the gear positioning member 6;

[0041] Step 4: While the grinding assembly 5 processes the gears fixed on the gear positioning member 6, the conveyor belt 3 works again until the spacing adjustment mechanism 8 completes the spacing adjustment of the corresponding number of gears;

[0042] Step 5: After the polishing assembly 5 finishes polishing the gear on the gear positioning member 6 , the robotic arm 10 drives the robotic gripper 11 to remove the gear from the gear positioning member 6 , and again clamps the gear on the conveyor belt 3 and places it on the gear positioning member 6 .

[0043] Working principle:

[0044] The gears are transmitted through the transmission belt 3, and the counter 12 counts the gears that have passed. When the number of gears that have passed is consistent with the number of gear positioning members 6, the first telescopic cylinder 15 drives the limit baffle 13 to move inside the groove 14 to close the two ends of the transmission belt 3 until the gears between the limit baffles 13 are close to each other. The transmission belt 3 stops working, the limit baffle 13 automatically resets, and the third telescopic cylinder 7 works to drive the adjusting head 27 at the bottom end of the spacing adjustment mechanism 8 to press against the gear. Then the second telescopic cylinder 24 works to drive the limit block 26 to move inside the limit rail 25, thereby driving the lifting plate 18 to move upward, and then driving the driving groove 19 to drive the driving mechanism 8. The movable arm 20 moves, so that the adjusting rod 23 and the adjusting head 27 drive the gears to adjust the spacing. After the gear spacing adjustment is completed, the robotic arm 10 drives the robotic gripper 11 to move, grabs the gears after the spacing adjustment, and places them on the gear positioning member 6. While the grinding assembly 5 processes the gears fixed on the gear positioning member 6, the conveyor belt 3 works again until the spacing adjustment mechanism 8 completes the spacing adjustment of the corresponding number of gears. After the grinding assembly 5 completes the fine grinding of the gears on the gear positioning member 6, the robotic arm 10 drives the robotic gripper 11 to remove the gears on the gear positioning member 6, and clamps the gears on the conveyor belt 3 again and places them on the gear positioning member 6.
