Technical Field

[0001] This utility model relates to the field of milling technology, specifically a milling tool for machining aluminum alloy products. Background Technology

[0002] Milling is a machining method that removes material from a workpiece by using a rotating milling cutter. The rotation of the milling cutter is the main motion, and the movement of the workpiece or the milling cutter is the feed motion. The cutting edge on the milling cutter cuts the workpiece material to obtain a part with a certain shape, size and surface quality.

[0029] The connecting mechanism 2 includes a connecting part and a control part;

[0030] The connecting part includes two connecting plates 26 and two fixing sleeves 211, and the control part includes a lifting ring 21 and a fixing frame 24;

[0031] The outer walls of mounting block 3 are fixedly connected to the outer walls of the two connecting plates 26. The adjacent sides of the two fixing sleeves 211 are fixedly connected to the outer wall of the tool holder 1. The outer walls of the two connecting plates 26 are slidably connected to the inner sides of the two fixing sleeves 211. Two fixing brackets 25 are fixedly installed on the outer wall of the tool holder 1. Two slots are respectively opened on the outer walls of the two connecting plates 26. Two inserts 210 are slidably inserted through the outer walls of the two fixing sleeves 211, extending to the inner walls of the two slots. Two through grooves are respectively opened on the outer walls of the two fixing brackets 25. Two control rods 28 are respectively installed on the inner walls of the two through grooves. The sides of the two control rods 28 near the lifting ring 21 are hinged to the outer wall of the lifting ring 21. Two control plates 29 are fixedly installed on the outer walls of the two inserts 210. The sides of the two control rods 28 near the two control plates 29 are hinged to the outer walls of the two control plates 29. The outer wall of the tool holder 1 is connected to the outer wall of the fixing frame 24. The fixed frame 24 is slidably connected to the inner side of the lifting ring 21. A connecting sleeve 22 is fixedly installed on the top surface of the lifting ring 21. The inner side of the connecting sleeve 22 is slidably connected to the outer wall of the fixed frame 24. A pressing screw 23 is threaded through the outer wall of the connecting sleeve 22 and extends to the inner side of the fixed frame 24. Two limit plates 213 are fixedly installed on the opposite side of the two control plates 29. Two fixing brackets 25 are slidably installed on the opposite side of the two limit plates 213 and extend to the outer side of the two fixing brackets 25. Two screws 212 are respectively installed on the outer side of the two fixing sleeves 211. The two screws 212 are threaded through the outer wall of the two fixing sleeves 211 and the inner side of the two connecting plates 26 on the adjacent side. A wedge-shaped groove is opened on the outer wall of the knife handle 1. A wedge block 27 is slidably installed on the inner wall of the wedge groove. The outer wall of the wedge block 27 is fixedly connected to the inner side of the lifting ring 21.

[0032] The milling mechanism 4 includes a milling rod 41, the bottom surface of which is fixedly connected to the bottom surface of the mounting block 3. The bottom surface of the milling rod 41 is provided with multiple chip-dispersing grooves 44, and the inner side of the multiple chip-dispersing grooves 44 is provided with multiple mounting grooves 47. Multiple milling cutters 46 are respectively installed on the inner side of the multiple mounting grooves 47 by multiple bolts.

[0033] When in use, when the mounting block 3 needs to be installed, the connecting plate 26 is inserted into the fixing sleeve 211. At this time, the slot on the connecting plate 26 is aligned with the fixing sleeve 211. When the lifting ring 21 slides down, the wedge block 27 pushes the control rod 28 to rotate around the hinge point with the fixing frame 25. The other end of the control rod 28 pulls the insert block 210 through the hinged control plate 29, so that it is inserted into the slot of the connecting plate 26, thereby locking the mounting block 3 and the tool holder 1. After the two insert blocks 210 are inserted into the inner walls of the two slots respectively, the extrusion screw 23 is tightened. After the extrusion screw 23 is tightened, the lifting ring 21 can be fixed, and then the two insert blocks 210 can be fixed. At the same time, the screw 212 passes through the fixing sleeve 211 and the connecting plate 26 for secondary fixation. The limit plate 213 restricts the movement of the control plate 29 to ensure stable connection.

[0034] During disassembly, rotate the squeezing screw 23 in the opposite direction. At this time, manually control the lifting ring 21 to move upward. The wedge block 27 drives the control rod 28 to rotate in the opposite direction. The insert block 210 is pulled out of the slot, and the screw 212 is unscrewed, so that the mounting block 3 and the tool holder 1 can be separated.

[0035] The end teeth 45 on the bottom surface of the milling rod 41, the peripheral teeth 43 on the outer wall, and the chip removal groove 42 and chip separating groove 44 work together to achieve milling of the workpiece.

[0036] During milling operations, the milling cutter is mounted on the machining equipment and rotates at high speed. The end teeth 45 and the peripheral teeth 43 contact the aluminum alloy workpiece and cut the workpiece through the cutting edge. The chip divider 44 divides the chips generated during the cutting process into small pieces, reducing the risk of chip entanglement and blockage, while reducing the cutting force and improving machining accuracy and surface quality. The chips are smoothly discharged through the chip discharge groove 42 to prevent chip accumulation from affecting the machining. The milling cutter 46, which is fixed in the mounting groove 47 by bolts, can be replaced with different specifications and types according to the machining requirements to adapt to different milling processes.
