[0002] Aerospace impellers are key components in core power devices such as aero-engines and gas turbines, and their performance directly affects the engine's efficiency, thrust, and reliability. Milling cutters are used in the machining process of aerospace impellers. Milling cutters are the core tools in impeller manufacturing, and their performance directly affects machining accuracy, efficiency, and surface quality.

[0003] Traditional milling cutters used for machining aerospace impellers are of a single integrated structure, and the use of a single milling cutter is relatively limited. Different types of milling cutters are required in the machining process of aerospace impellers, and the operation of constantly switching, disassembling and replacing different types of milling cutters is cumbersome and inconvenient. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a milling cutter for machining aerospace impellers, thereby solving the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A milling cutter for machining aerospace impellers includes:

[0007] A milling cutter mounting rod has a rod cavity and a first threaded groove on its outer surface;

[0008] A milling head switching assembly is disposed within the cavity of a milling cutter mounting rod. The milling head switching assembly is configured to be able to rotate within the cavity of the milling cutter mounting rod, thereby enabling the milling head switching assembly to switch milling heads.

[0009] An internally threaded cylinder, its threads being installed on the first threaded groove of the milling cutter mounting rod, is used to limit the position of the milling head switching assembly.

[0010] Preferably, a rod shaft is fixedly installed on the inner wall of the rod cavity on the milling cutter mounting rod.

[0011] Preferably, the milling head switching component includes:

[0012] A flip plate with a circular opening is rotatably fitted onto a rod shaft.

[0013] The first milling head is fixedly mounted on the bottom side of the tilting plate;

[0014] The second milling head is fixedly mounted on the top side of the flip plate.

[0015] Preferably, the flip plate is adapted to the rod cavity of the milling cutter mounting rod, and both outer walls of the flip plate are arc-shaped and adapted to the milling cutter mounting rod. The outer walls of the flip plate are respectively provided with a second threaded groove and a third threaded groove.

[0016] Preferably, the first threaded groove of the milling cutter mounting rod is adapted to the second threaded groove of the flip plate, and the second and third threaded grooves on the flip plate are symmetrically arranged and have opposite thread directions.

[0017] Preferably, the internal threaded cylinder is threaded onto the first threaded groove of the milling cutter mounting rod and the second threaded groove of the flip plate.

[0018] Preferably, the outer surface of the internally threaded cylinder has multiple arc-shaped grooves, which are distributed in a circumferential array.

[0019] When the internal threaded cylinder is screwed upwards to the position above the first threaded groove of the milling cutter mounting rod, the first and second milling heads on the flip plate can be rotated and switched within the rod cavity of the milling cutter mounting rod. The corresponding milling head on the milling cutter mounting rod can be selected according to the actual situation of machining aerospace impellers. Then, the internal threaded cylinder is screwed downwards to install it on the second or third threaded groove of the flip plate, thereby limiting and fixing the position of the flip plate within the rod cavity of the milling cutter mounting rod. In this application, a single milling cutter has two switching milling modes, which can avoid the need to frequently switch and disassemble different types of milling cutters during the machining of aerospace impellers, making the operation simple and fast.

[0029] like Figure 6 As shown, the milling cutter mounting rod 100 has a rod cavity 101, and a rod shaft 1011 is fixedly mounted on the inner wall of the rod cavity 101. The milling head switching assembly 200 is disposed in the rod cavity 101 of the milling cutter mounting rod 100. The milling head switching assembly 200 is configured to be able to flip within the rod cavity 101 of the milling cutter mounting rod 100, so that the milling head switching assembly 200 can switch milling heads. The milling head switching assembly 200 includes: a flip plate 201, a first milling head 202, and a second milling head 203. The flip plate 201 has a circular opening, and the circular opening of the flip plate 201 is rotatably sleeved on the rod shaft 1011. The first milling head 202 is fixedly mounted on the bottom side of the flip plate 201. The second milling head 203 is fixedly mounted on the top side of the flip plate 201.

[0030] Continue as Figure 6As shown, the flip plate 201 is adapted to the rod cavity 101 of the milling cutter mounting rod 100. Both outer walls of the flip plate 201 are arc-shaped and adapted to the milling cutter mounting rod 100. At the same time, the outer surface of the milling cutter mounting rod 100 and the outer wall of the flip plate 201 respectively have a first threaded groove 102 and a second threaded groove 2011. The first threaded groove 102 of the milling cutter mounting rod 100 is adapted to the second threaded groove 2011 of the flip plate 201. Meanwhile, the flip plate 201 also has a third threaded groove 2012. The second threaded groove 2011 and the third threaded groove 2012 on the flip plate 201 are symmetrically arranged and the threads have opposite directions.

At the same time, the internal threaded cylinder 300 can be screwed downwards onto the second threaded groove 2011 or the third threaded groove 2012 of the flip plate 201. The internal threaded cylinder 300 can be used to limit the position of the flip plate 201 within the rod cavity 101 of the milling cutter mounting rod 100.

[0032] like Figure 6 As shown, the outer surface of the internally threaded cylinder 300 has multiple arc-shaped grooves 301, which are arranged in a circumferential array; this makes it convenient for installers to hold the internally threaded cylinder 300 and adjust it by screwing.

[0033] When the internal threaded cylinder 300 is screwed upwards to a position above the first threaded groove 102 of the milling cutter mounting rod 100, the first milling head 202 and the second milling head 203 on the flip plate 201 can be rotated and switched within the rod cavity 101 of the milling cutter mounting rod 100. The corresponding milling head on the milling cutter mounting rod 100 can be selected according to the actual situation of machining aerospace impellers. Then, the internal threaded cylinder 300 is screwed downwards to install the internal threaded cylinder 300 on the second threaded groove 2011 or the third threaded groove 2012 of the flip plate 201, thereby limiting and fixing the position of the flip plate 201 within the rod cavity 101 of the milling cutter mounting rod 100. In this application, a single milling cutter has the ability to switch between two milling modes, which avoids the need to frequently switch and disassemble different types of milling cutters during the machining of aerospace impellers, making the operation simple and fast.
