[0017] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0018] according to Figure 1 , 2As shown in Figure 3, this embodiment proposes a grinding device for milling cutter production, including a base plate 1, a mounting seat 2 installed on one side of the top of the base plate 1, a grinding component 3 installed on one side of the mounting seat 2, a controller 4 installed at the front end of the mounting seat 2, a moving mechanism provided inside the base plate 1, a mounting plate 5 installed above the base plate 1, a mounting frame 6 installed above the mounting plate 5, an adjustment mechanism provided at the top of the mounting plate 5 and the inner side of the mounting frame 6, a clamping cavity 7 installed at one end of the adjustment mechanism, a first cylinder 8 installed at the top of the clamping cavity 7, a positioning plate 9 installed inside the clamping cavity 7, and one end of the first cylinder 8 connected to one end of the positioning plate 9.

[0019] The adjustment mechanism includes a fixed cavity 10, a second cylinder 11, a transmission rack 12, a transmission gear 13, a transmission rod 14, and a limiting structure. The fixed cavity 10 is respectively installed on the top of the mounting plate 5 and the inner side of the mounting bracket 6. The second cylinder 11 is installed on one side inside the fixed cavity 10. The transmission rack 12 is installed at the output end of the second cylinder 11. The transmission gear 13 meshes above the transmission rack 12. The transmission rod 14 is installed at the top of the transmission gear 13. One end of the transmission rod 14 is connected to the bottom end of the mounting bracket 6 and one end of the clamping cavity 7. When it is necessary to adjust the angle of the milling cutter, the mechanism is activated. The second cylinder 11 is activated. Under the limitation of the positioning groove 17 and the positioning block 18, the second cylinder 11 drives the transmission rack 12 to move. Since the transmission rack 12 and the transmission gear 13 mesh with each other, the transmission gear 13 is driven to rotate. Then, under the limitation of the limiting rail 15 and the limiting block 16, the transmission gear 13 drives the transmission rod 14 to move, thus driving the milling cutter to move. The milling cutter is adjusted to an appropriate position according to the actual situation and then ground. This makes the milling cutter more thoroughly ground, resulting in a better grinding effect and greatly improving the practicality of the equipment.

[0020] The limiting structure includes a limiting rail 15, a limiting block 16, a positioning groove 17, and a positioning block 18. The limiting rail 15 is installed at the top of the fixed cavity 10. The limiting block 16 is provided inside the limiting rail 15, and one end of the limiting block 16 is connected to one end of the transmission rod 14. The positioning groove 17 is opened at one end inside the fixed cavity 10, and the positioning block 18 is provided inside the positioning groove 17. One end of the positioning block 18 is connected to one end of the transmission rack 12. The limiting rail 15 has an arc-shaped design. The limiting rail 15 and the transmission... The centers of the moving gear 13 are on the same straight line. The cross-section of the positioning groove 17 is larger than the cross-section of the positioning block 18. The positioning groove 17 and the positioning block 18 form a sliding structure. In use, the mutual cooperation between the limiting rail 15 and the limiting block 16 can limit the movement of the transmission rod 14, making the transmission rod 14 more stable when moving. The mutual cooperation between the positioning groove 17 and the positioning block 18 can limit the movement of the transmission rack 12, making the transmission rack 12 more stable when moving.

[0021] The moving mechanism includes a servo motor 19, a threaded rod 20, a threaded sleeve 21, a fixed groove 22, and a movable block 23. The servo motor 19 is mounted on one end of the base plate 1, and the threaded rod 20 is mounted inside the base plate 1. The output end of the servo motor 19 is connected to one end of the threaded rod 20. A threaded sleeve 21 is provided on the outer wall of the threaded rod 20, and the top end of the threaded sleeve 21 is connected to the bottom end of the mounting plate 5. The fixed groove 22 is opened on both sides inside the base plate 1, and a movable block 23 is provided inside the fixed groove 22. One end of the movable block 23 is connected to the outer side of the threaded sleeve 21. In use, the servo motor 19 is started to drive the threaded rod 20 to rotate. Therefore, under the limitation of the fixed groove 22 and the movable block 23, the threaded rod 20 drives the threaded sleeve 21 to move, thereby driving the milling cutter to move. This makes the milling cutter contact with the grinding assembly 3, making the milling cutter more convenient and faster to grind, thus greatly improving the convenience of the equipment in use.

[0022] Both the clamping cavity 7 and the positioning plate 9 are provided with anti-slip pads on their inner sides. The design of the anti-slip pads makes the milling cutter more stable during grinding and prevents it from slipping.

[0023] Working principle: The operator first places the shank of the milling cutter inside the clamping cavity 7, then starts the first cylinder 8 to move the positioning plate 9 downwards, using the positioning plate 9 to clamp and fix the milling cutter. Then, the servo motor 19 is started to rotate the threaded rod 20. Therefore, under the limitation of the fixed groove 22 and the movable block 23, the threaded rod 20 drives the threaded sleeve 21 to move, thereby moving the milling cutter. At this time, the grinding assembly 3 is started to grind the milling cutter. When it is necessary to adjust the angle of the milling cutter, the second cylinder 11 is started. Under the limitation of the positioning groove 17 and the positioning block 18, the second cylinder 11 drives the transmission rack 12 to move. Since the transmission rack 12 and the transmission gear 13 mesh with each other, the transmission gear 13 is driven to rotate. Then, under the limitation of the limiting rail 15 and the limiting block 16, the transmission gear 13 drives the transmission rod 14 to move, thereby moving the milling cutter. The milling cutter is adjusted to an appropriate position according to the actual situation and then ground.
