[0033] In the utility model, by adopting the above-mentioned design, during operation, the connecting column 1 rotates at high speed, and the sliding block 301 will always be tightly connected with the screw rod 3 due to the centrifugal force, and then the protrusion on the screw rod 3 is limited by the clamping block 302 arranged thereon, so that when the workpiece is processed, the screw rod 3 will not rotate and then become loose due to the vibration generated by the contact between the milling head 2 and the workpiece, so that the connection between the connecting column 1 and the milling head 2 is more stable.

[0034] Furthermore, as a specific implementation of the utility model, the utility model provides a high-precision combined alloy forming milling cutter.

[0035] Specifically, Figure 1-Figure 4 As shown, a limiting block 304 is integrally formed on the sliding block 301 , and the limiting block 304 is adapted to the sliding groove 103 . The area of ​​the limiting block 304 is smaller than the connection point between the sliding groove 103 and the side of the connecting column 1 .

[0036] In the present invention, by adopting the above-mentioned design, the sliding block 301 cannot escape from the sliding groove 103, making the device safer.

[0037] Furthermore, as a specific implementation of the utility model, the utility model provides a high-precision combined alloy forming milling cutter.

[0039] In the present invention, by adopting the above-mentioned design, the sliding block 301 is always in close contact with the protrusion on the screw rod 3 under normal conditions, and thus the screw rod 3 is fixed by the clamping block 302 under normal conditions without human intervention.

[0040] Furthermore, as a specific implementation of the utility model, the utility model provides a high-precision combined alloy forming milling cutter.

[0041] Specifically, Figure 4 As shown, the clamping block 302 is provided with a chamfer, and the direction of the chamfer is the same as the tightening direction of the thread. There are ten clamping blocks 302, which are arranged in a circular array around the through hole at equal intervals on the contact surface between the sliding block 301 and the screw rod 3.

[0042] In the utility model, by adopting the above-mentioned design, when installing the milling cutter head 2, the screw rod 3 can be directly screwed on, and the sliding block 301 can be pressed to make the clamping block 302 move away from the connecting column 1. The screw rod 3 can press the sliding block 301 down by chamfering, making the installation of the milling cutter head 2 more convenient.

[0043] Furthermore, as a specific implementation of the utility model, the utility model provides a high-precision combined alloy forming milling cutter.

[0045] In the utility model, by adopting the above-mentioned design, when the staff needs to remove the milling head 2 for inspection or maintenance, there is no need to press the sliding block 301 with fingers. The sliding block 301 can be driven away from the screw 3 by pressing the push rod 305, so that the clamping block 302 no longer limits the screw 3 in one direction, and the screw 3 can be reversed, thereby completing the disassembly of the milling head 2 more conveniently.

[0046] Furthermore, as a specific implementation of the utility model, the utility model provides a high-precision combined alloy forming milling cutter.

[0047] Specifically, Figure 1-Figure 4 As shown, a toggle block 306 is provided on a side of the screw rod 3 away from the connecting column 1 .

[0048] In the utility model, by adopting the above-mentioned design, the staff can rotate the screw rod 3 through the toggle block 306 provided on the screw rod 3, making it more convenient for the staff to apply force when rotating the screw rod 3.

[0049] Working principle:

[0050] In order to prevent the screw rod 3 from vibrating due to the contact between the milling cutter head 2 and the workpiece during the processing, resulting in loosening and falling off.

[0051] In the utility model, a fixing component is provided.

[0052] When the milling head 2 contacts the workpiece and generates vibration during rotation, and the vibration is fed back to the screw 3, the screw 3 will be limited by the clamping block 302 set on the sliding block 301, thereby preventing the screw 3 from loosening due to the transmitted vibration, causing the connection between the connecting column 1 and the milling head 2 to loosen, resulting in a safety hazard.
