[0027] The following provides a further detailed description of this application.

[0028] This application discloses a composite disc milling tool for milling teeth and milling tooth tips.

[0029] Reference Figures 1-3A composite disc milling cutter for milling gear teeth and milling gear tips includes a cutter head 1. Multiple milling gear tip inserts 12, multiple first side tooth inserts 13, multiple second side tooth inserts 18, and multiple coarse milling gear inserts 14 are arranged circumferentially around the cutter head 1. The milling gear tip inserts 12 are mounted on the cutter head 1 via a connecting component 1 21. The first side tooth inserts 13 and second side tooth inserts 18 are both mounted on the cutter head 1 via a connecting component 2 22, and the milling gear tip inserts 12 and second side tooth inserts 18 cooperate to mill the gear tips. The coarse milling gear inserts 14 are mounted on the cutter head 1 via a connecting component 3 23, and together with the first side tooth inserts 13, are used to perform rough milling on the gear. The number of the milling gear tip inserts 12, first side tooth inserts 13, second side tooth inserts 18, and coarse milling gear inserts 14 can be selected as needed.

[0030] The cutter head 1 has symmetrically arranged conical mounting surfaces 11, with the diameter of the two mounting surfaces 11 being the largest at one end. The coarse milling insert 14 is located at the point where the diameter of the two mounting surfaces 11 is the largest. At the same time, multiple first side tooth inserts 13 are arranged in two sets on the two mounting surfaces 11 and are staggered with each other. Multiple milling top inserts 12 are also arranged in two sets on the two mounting surfaces 11 and are staggered with each other. Multiple first side tooth inserts 13 and multiple second side tooth inserts 18 are located between the milling top inserts 12 and the coarse milling insert 14. The second side tooth inserts 18 and the milling top inserts 12 are arranged correspondingly, and the first side tooth inserts 13 and the coarse milling inserts 14 are arranged correspondingly.

[0031] On the mounting surface 11, at the locations of the first side toothed insert 13, the second side toothed insert 18, and the rough milling insert 14, there are snap-fit ​​grooves 15 and chip removal grooves 16. The first side toothed insert 13, the second side toothed insert 18, and the rough milling insert 14 are snap-fitted onto the snap-fit ​​grooves 15, with their adjacent side walls abutting against the snap-fit ​​grooves 15 for positioning. The connecting components 22 and 3 are both screws. The screws pass through the first side toothed insert 13 and the rough milling insert 14 and are threaded into the snap-fit ​​grooves 15, thereby fixing the first side toothed insert 13, the second side toothed insert 18, and the rough milling insert 14. At the same time, the side walls of the first side toothed insert 13, the second side toothed insert 18, and the rough milling insert 14 are located outside the snap-fit ​​grooves 15. The chip removal grooves 16 are used to remove chips after machining.

[0032] Adjustment slots 17 are provided on the mounting surface 11 and at the milling cutter insert 12. A cutter clip 3 is slidably mounted on the adjustment slot 17 along the radial direction of the cutter head 1. The adjustment component 4 is used to adjust the cutter clip 3 to different positions. The end of the cutter clip 3 away from the center of the cutter head 1 extends out of the adjustment slot 17 and has a connecting slot 31. The milling cutter insert 12 is inserted and mounted on the connecting slot 31, and the adjacent side walls of the milling cutter insert 12 abut against the connecting slot 31 for positioning. The connecting component 21 is a screw. The screw passes through the milling cutter insert 12 and is threadedly connected to the connecting slot 31, and the head of the screw presses against the milling cutter insert 12 for positioning.

[0033] The adjustment assembly 4 includes a pad 41, a fixing member 42, and a locking member 43. The pad 41 is snapped onto the adjustment groove 17 and is positioned against the end of the adjustment groove 17 near the center of the cutter head 1. The pad 41 abuts against the tool holder 3 and is used to support and position the tool holder 3. The fixing member 42 is used to fix the position of the pad 41. The fixing member 42 is a screw. The screw passes through the pad 41 and is threaded into the adjustment groove 17. The head of the screw is located inside the fixing member 42 and presses against the pad 41 for positioning. After adjusting the position of the tool holder 3, the pad 41 of the corresponding size needs to be replaced to better support and position the tool holder 3 and improve the machining quality of the milling tooth insert 12.

[0034] The tool holder 3 has an adjustment hole 32 that passes through the tool disc 1 radially. The tool holder 3 has a stepped hole 33 that is radially formed on the side wall of the tool disc 1 on the side away from the adjustment groove 17. The width of the stepped hole 33 is greater than the width of the adjustment hole 32. The locking member 43 is a screw that passes through the adjustment hole 32 and is threaded to the adjustment groove 17. The head of the locking member 43 is located in the stepped hole 33 and presses against the stepped hole 33 for positioning, thereby positioning the tool holder 3. After the locking member 43 is unlocked, the fixing member 42 is unlocked and the pad 41 is removed. The pad 41 of appropriate size is snapped into the adjustment groove 17 and abuts against the end of the adjustment groove 17 near the center of the tool disc 1 for positioning. Positioning is achieved by the fixing member 42. Then the tool holder 3 is pushed against the pad 41 for positioning. Finally, the locking member 43 positions the tool holder 3.

[0035] The working principle of this application embodiment is as follows: The rough milling insert 14 and the first side tooth insert 13 work together to rough mill the gear, while the top milling insert 12 and the second side tooth insert 18 work together to mill the top of the gear. This allows the two processes to be completed in one go, which greatly saves the time spent on gear processing, improves the accuracy of the two processes, and improves processing efficiency and quality.

[0036] After the locking piece 43 and the fixing piece 42 are unlocked, the pad 41 is removed. The pad 41 of the appropriate size is snapped into the adjusting groove 17 and positioned against the adjusting groove 17. Positioning is achieved by the fixing piece 42. Then, the tool holder 3 is pushed against the pad 41 for positioning. Finally, the locking piece 43 positions the tool holder 3, thereby enabling the adjustment of the positions of multiple milling tooth inserts 12, improving the machining range. At the same time, positioning by multiple pads 41 improves the machining quality.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
