An electric push rod 1063 is fixedly connected to the outer side of 064, and one side of the electric push rod 1063 is fixedly connected to the second mounting bracket 1052; in the initial state, the limiting gear body 1061 and the braking gear body 1051 are engaged with each other to limit the braking gear body 1051, and the braking gear body 1051 limits the angle of the driven gear body 1041 and locks the frame assembly 1. When the angle needs to be adjusted, the electric push rod 1063 is driven to move away from the braking gear body 1051, thereby driving the limiting gear body 1061 and the braking gear body 1051 to no longer engage. At this time, the braking gear body 1051 can be rotated by rotating the handle 1053, thereby driving the driven gear body 1041 and the outer frame 101 to rotate to adjust the deflection angle.

[0028] In a preferred embodiment, the length of the upper clamp 2 and the length of the lower clamp assembly 3 are both the same as the difference between the inner length of the outer frame 101 and the outer length of the protective box 102; the servo motor 305 is set in the protective box 102 to protect it.

[0029] In a preferred embodiment, a bearing is provided at the connection between the driven gear body 1041 and the first mounting bracket 1043 , a bearing is provided at the connection between the brake gear body 1051 and the second mounting bracket 1052 , and the mounting shaft 1042 is fixedly connected to the outer frame 101 .

[0030] In a preferred embodiment, a limit movable groove is opened on the back side of the outer frame 101, and the limit block 1062 is movably connected to the inner side of the outer frame 101; the electric push rod 1063 is driven to move away from the brake gear body 1051, thereby driving the limit gear body 1061 and the brake gear body 1051 to no longer engage, and during the movement of the limit gear body 1061, the limit block 1062 moves in the limit movable groove of the outer frame 101.

[0031] In a preferred embodiment, the teeth of the braking gear body 1051 are meshed with the teeth of the driven gear body 1041 and the teeth of the limiting gear body 1061 .

[0032] The working principle of the utility model is as follows: according to the angle size of the corner of the unprocessed milling cutter of different models, the angle between the upper clamp 2 and the lower clamp assembly 3 is adjusted to stably clamp the unprocessed milling cutter, the servo motor 305 is started, and the servo motor 305 drives the rotating shaft 304 to rotate the specified angle to match the angle of the corner of the processed milling cutter. When the rotating shaft 304 rotates, it drives the lower clamp body 301 and the cross bar 303 to rotate synchronously, such as Figure 6 As shown, the metal debris generated by cutting leaks from the chip leakage groove 302 into the outer frame 101. During the movement of the outer frame 101, the debris will be discharged from the chip discharge groove 103 to prevent the debris from accumulating on the lower clamp body 301 and wearing the blade during the next milling cutter clamping process;

[0033] The deflection angle of the unprocessed milling cutter that has been stably clamped is adjusted according to production requirements. In the initial state, the limiting gear body 1061 and the braking gear body 1051 are engaged with each other to limit the braking gear body 1051. The braking gear body 1051 limits the angle of the driven gear body 1041 and locks the frame assembly 1. When the angle needs to be adjusted, the electric push rod 1063 is driven to move away from the braking gear body 1051, thereby driving the limiting gear body 1061 and the braking gear body 1051 to no longer engage. At this time, the braking gear body 1051 can be rotated by rotating the handle 1053, thereby driving the driven gear body 1041 and the outer frame 101 to rotate to adjust the deflection angle. The number of teeth of the driven gear body 1041 is three times the number of teeth of the braking gear body 1051, and the adjustment accuracy is high. After adjusting to the specified angle, the electric push rod 1063 is driven to reset to limit the braking gear body 1051.
