[0019] like Figures 1 to 3 As shown, the milling device for graphite processing of the utility model includes a connecting block 10 and a milling cutter 11. The upper end of the connecting block 10 is fixed to a machine tool body 12, and the lower end of the connecting block 10 is provided with a milling cutter 11 for milling a graphite workpiece. The lower end of the connecting block 10 is fixed to a locking rod 21, and the upper end of a rotating drum 22 is rotatably connected to the locking rod 21. The milling cutter 11 is installed at the lower end of the rotating drum 22. A retractable locking pin 23 is provided in the rotating drum 22. The rotating drum 22 rotates around the locking rod 21 to adjust the orientation angle of the milling cutter 11, and contacts with the locking rod 21 through the locking pin 23 to lock.

[0020] The utility model manually rotates the rotating drum 22 around the locking rod 21 to adjust the orientation angle of the milling cutter 11, and locks it by contacting the locking pin 23 with the locking rod 21. There is no need to additionally set up a steering mechanism and a locking mechanism. The structure is simple, and it is easy to switch and adjust the orientation angle of the milling cutter 11, and is suitable for different working conditions.

[0021] The machine tool body 12 is provided with a mechanism capable of adjusting the overall structure of the milling device for graphite processing of the utility model to move and rotate in space, thereby expanding the scope of application. The mechanism is a prior art and will not be described in detail here.

[0022] Preferably, a rotating hole 24 is formed on the rotating drum 22 , and a locking rod 21 is sleeved in the rotating hole 24 .

[0023] Preferably, a guide hole 25 is provided in the rotating cylinder 22, and a locking pin 23 sliding along the guide hole is installed in the guide hole 25 through a compression spring 26, and the end of the locking pin 23 can contact the clamping surface 27, and multiple clamping surfaces 27 are evenly provided on the outer surface of the locking rod 21 along the circumferential direction.

[0024] The utility model manually rotates the rotating drum 22 around the locking rod 21 to adjust the orientation angle of the milling cutter 11. At the same time, the end of the locking pin 23 first moves from one clamping surface 27 to contact the outer surface of the locking rod 21, and then moves to contact the other clamping surface 27, thereby locking the orientation angle of the milling cutter 11.

[0025] Among them, technical personnel in this field can change the number and spacing angles of the clamping surfaces 27 according to actual applications to achieve different numbers and angles of adjustment of the milling cutter 11; in addition, the shape of the clamping surface 27 and the locking pin 23 can also be changed so that the end of the locking pin 23 can contact the clamping surface 27 to limit the rotation of the drum 22 around the locking rod 21.

[0026] Preferably, the locking pin 23 is arranged along the radial direction of the locking rod 21 .

[0027] Preferably, see Figure 1 , 2 The engaging surface 27 is a plane, the plane is parallel to the tangent plane of the locking rod 21, and the locking pin 23 is a flat head pin matched with the plane.

[0029] As a structural variation of the present invention, see Figure 3 The engaging surface 27 is an inner concave arc surface, and the locking pin 23 is a round head pin matched with the inner concave arc surface.

[0030] The engaging surface 27 and the locking pin 23 may also be other structures, and the present utility model only lists the above two preferred solutions.

[0032] The structure of the clamping device 15 may refer to the clamping method of the impact drill bit, which is a prior art and will not be described in detail here.

[0033] Preferably, the connecting block 10 is a C-shaped block, and a locking rod 21 is fixed inside the C-shaped block.

[0034] The working principle of the utility model is as follows:

[0035] First, fix the milling cutter 11 on the clamping device 15, start the motor 14, and drive the milling cutter 11 to rotate to perform milling processing on the graphite workpiece; when the orientation angle of the milling cutter 11 needs to be adjusted, manually turn the rotating drum 22 to rotate it around the locking rod 21 to adjust the orientation angle of the milling cutter 11. At the same time, the end of the locking pin 23 first moves from one clamping surface 27 to contact with the outer surface of the locking rod 21, and then moves to contact with the other clamping surface 27, thereby locking the orientation angle of the milling cutter 11. There is no need to additionally set up a steering mechanism and a locking mechanism. The structure is simple, easy to switch and adjust the orientation angle of the milling cutter 11, and suitable for different working conditions.
