[0023] The technical solutions in the embodiments of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Specific embodiment 1

[0025] See also Figure 1-4 The utility model is a taper milling cutter for processing rare earth titanium alloy materials, comprising a fixed column 1, a cutter head 2 is fixedly connected to the bottom of the fixed column 1, and a mounting column 3 is arranged on the top of the fixed column 1;

[0026] A fixing assembly is provided on the top of the fixing column 1, and the fixing assembly includes a fixing rod 4, which is fixed to the top of the fixing column 1, a clamping groove 5 is provided on one side of the fixing rod 4, a square groove 6 is provided on the bottom of the fixing column 1, a semicircular groove 7 is provided on one side of the fixing column 1, a clamping plate 8 is provided inside the semicircular groove 7, and a fixing sleeve 9 is threadedly connected to the top of the surface of the fixing column 1.

[0027] Specifically: the top of the mounting column 3 is installed and connected to the driving head of an external driving device, and the mounting column 3 and the cutter head 2 are driven to rotate by the external driving device to realize cutting processing. The fixing rod 4 is cylindrical and can be inserted into the circular groove 10. The semicircular groove 7 is opened on one side of the fixing column 1, and its thickness is the same as the thickness of the clamping plate 8 and the clamping groove 5. After the cutter head 2 is connected to the mounting column 3, the design weight of the cutter head 2 and the mounting column 3 on both sides is the same, which can maintain relative balance when the mounting column 3 drives the cutter head 2 to rotate. Specific embodiment 2

[0029] See also Figure 1-4 On the basis of the specific embodiment 1, a circular groove 10 is opened inside the square groove 6, an internal thread is opened inside the fixing sleeve 9, the size of the square groove 6 is the same as that of the fixing column 1, the thickness of the clamping groove 5 is the same as that of the clamping plate 8, and a pin is movably connected inside the clamping plate 8. The top and bottom of the pin are fixedly connected to the inner wall of the semicircular groove 7. The length of the cutter head 2 is 50MM, the minimum diameter of the cutter head 2 is 2MM, the maximum diameter of the cutter head 2 is 8MM, and the surface of the cutter head 2 is provided with an aluminum titanium nitride coating.

[0030] Specifically: an internal thread is provided inside the fixing sleeve 9, and an external thread is provided on the surface of the mounting column 3. When the fixing sleeve 9 is rotated, the thread can be used to move it up and down, so as to conveniently cover the clamping plate 8. One side of the clamping plate 8 is movably connected to the inner wall of the semicircular groove 7 through a pin shaft, so that the staff can conveniently rotate the clamping plate 8. An aluminum titanium nitride coating is provided on the surface of the cutter head 2. The aluminum titanium nitride coating usually has a very high hardness, so that the metal surface can better resist scratches and wear. Since aluminum nitride and titanium nitride have good chemical stability, the coating can provide a certain degree of corrosion protection and extend the service life of the cutter head 2.

[0031] The working principle of the utility model is as follows: when the cutter head 2 needs to be disassembled, the staff manually rotates the fixing sleeve 9 to move the fixing sleeve 9 upward, and the fixing sleeve 9 moves upward to remove the shielding of the clamping plate 8, and then manually rotates the clamping plate 8 to disengage the clamping plate 8 from the clamping groove 5. Figure 4 As shown, the cutter head 2 is then moved downward, and the cutter head 2 drives the fixed column 1 to disengage from the square groove 6. The movement of the fixed column 1 simultaneously drives the fixed rod 4 to disengage from the circular groove 10, so that the fixed column 1 is separated from the mounting column 3, and the quick disassembly can be completed, which is convenient for the staff to replace. The entire disassembly process does not require the aid of external tools, saving time and effort.

[0032] The standard parts used in the present invention can all be purchased from the market and can be customized according to the description in the specification and drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art. The machinery, parts and equipment all adopt conventional models in the prior art. The control method is automatically controlled by a control unit.
