[0002] The alloy bar stock required for aerospace gear cutting is a key material for manufacturing high-performance aerospace gears. Prior to cutting, the alloy bar stock undergoes a complex series of heat treatment processes to ensure gear performance and quality. After heat treatment, the alloy bar stock is ready for cutting to form the gear. During the cutting process, strict control of cutting parameters and tool selection is required to ensure gear precision and surface quality.

[0003] In the prior art, an alloy rod for aerospace gear cutting, such as that disclosed in Publication No. CN221516376U, comprises an alloy rod body, an alloy rod material assembly mechanism, and an alloy rod cooling mechanism located within the alloy rod body. The alloy rod cooling mechanism includes a coolant reservoir, below which are connected first and second coolant flow channels. This alloy rod cooling mechanism increases the coolant's residence time within the alloy rod body, improving the cooling effect. Furthermore, the high-pressure coolant prevents waste chips from clogging the first and second coolant discharge ports.

[0004] The alloy rod cooling mechanism set up in the above technical solution can increase the time that the coolant stays inside the alloy rod body and improve the cooling effect. However, when it is used, if the cutting edge is damaged, the entire alloy rod can only be replaced, and the clamping end of the rod is not damaged, resulting in a wasteful replacement of the entire rod. In view of this, an alloy rod for aerospace gear cutting processing is provided to overcome the above-mentioned defects. Utility Model Content

[0005] The utility model provides an alloy rod for aerospace gear cutting to solve the above-mentioned problem that only the entire alloy rod can be replaced while the clamping end of the rod is not damaged, resulting in wasteful replacement of the entire rod.

[0009] As a further solution of the present invention: the cooling mechanism includes a mounting shell, the mounting shell is sleeved on the outer surface of the material rod body, and the outer wall of the mounting shell is provided with a water inlet.

[0010] As a further solution of the present invention: the outer wall of the material rod body is provided with a flow hole interconnected with the mounting shell, and the end of the cutting end is provided with a water spray port interconnected with the flow hole.

[0011] As a further solution of the present invention: a fixed bearing sleeved on the material rod body is fixed to the inner wall of the mounting shell.

[0012] As a further solution of the present invention: two limiting rings are fixed inside the mounting shell, and one side of the two limiting rings is slidably connected to an upper limiting groove provided on the material rod body.

[0013] As a further solution of the present invention: two connecting rods are symmetrically fixed to one end of the mounting shell, and the ends of the two connecting rods are telescopically connected to the limiting tube.

[0014] The beneficial effect of the utility model is that by unscrewing the fixing bolt on the material rod body, the end of the fixing bolt is separated from the fixing hole, the fixation of the connecting piece is released, and with the cooperation of the connecting hole, the cutting end can be separately disassembled, which is convenient for replacing the cutting end of the material rod separately, and has strong practicality.

The end of the connecting piece 3 is plugged into a connecting hole 31 provided on the inner wall of the material rod body 1. A fixing hole 32 is provided on the outer surface of the connecting piece 3. The inside of the fixing hole 32 is plugged into a fixing bolt 33 installed on the material rod body 1. A chip groove 4 is provided on the outer surface of the cutting end 2. When the cutting end 2 is damaged, the fixing bolt 33 on the material rod body 1 can be unscrewed, and the end of the fixing bolt 33 is separated from the fixing hole 32 to release the fixation of the connecting piece 3. With the cooperation of the connecting hole 31, the cutting end 2 can be disassembled separately, which is convenient for replacing the cutting end 2 of the material rod separately, and has strong practicality.

The rod body 1 rotates, thereby driving the cutting end 2 to cut the workpiece. At the same time, the external water pipe transports coolant to the mounting shell 5. The coolant enters the mounting shell 5, and then enters the interior of the cutting end 2 through the flow hole 52, and then is sprayed out through the water nozzle 53. The coolant can cool the cutting end 2, and the sprayed coolant will cool the cutting edge of the outer wall of the cutting end 2. Through the chip groove 4 opened on the cutting end 2, the waste chips generated during the workpiece processing can be discharged to the outside. Through the fixed bearing 54 provided in the mounting shell 5, the material rod body 1 will not drive the mounting shell 5 to rotate when it rotates, thereby ensuring the delivery of coolant. The set limit ring 55 and limit groove 56 can play a limiting role to avoid displacement of the mounting shell 5.

[0025] Working principle: Before using the alloy rod for aerospace gear cutting, first connect and fix the rod body 1 and the output shaft of the cutting equipment, and then connect the limit tube 7 and the outer shell of the cutting equipment. With the cooperation of the connecting rod 6, the limit tube 7 can be pulled to move, which is convenient for adjusting the length of the limit tube 7. The water inlet 51 provided on the mounting shell 5 is connected to the external water pipe. When in use, the cutting equipment drives the rod body 1 to rotate, and then drives the cutting end 2 to cut the workpiece. At the same time, the external water pipe transports coolant into the mounting shell 5. The coolant enters the mounting shell 5, and then enters the interior of the cutting end 2 through the flow hole 52, and then is sprayed out through the water nozzle 53. The coolant can cool the cutting end 2, and the spray The coolant discharged will cool the cutting edge of the outer wall of the cutting end 2. Through the chip groove 4 opened on the cutting end 2, the waste chips generated during the workpiece processing can be discharged to the outside. Through the fixed bearing 54 arranged in the mounting shell 5, the material rod body 1 will not drive the mounting shell 5 to rotate when it rotates, thereby ensuring the delivery of the coolant. The set limit ring 55 and limit groove 56 can play a limiting role to avoid the displacement of the mounting shell 5. When the cutting end 2 is damaged, the fixing bolt 33 on the material rod body 1 can be unscrewed, and the end of the fixing bolt 33 is separated from the fixing hole 32 to release the fixation of the connecting part 3. With the cooperation of the connecting hole 31, the cutting end 2 can be disassembled separately, which is convenient for the separate replacement of the cutting end 2 of the material rod, and is highly practical.
