Specifically, the milling fixture mechanism includes a first base 203, the first base 203 being mounted on a first movable stage 202 of the first conveying mechanism 201. The first conveyor 201 may drive the first base 203 on the first movable table 202 to move under the milling head of the milling machine 106. The first conveying mechanism 201 can be made of a ball screw nut pair matched with a sliding rail.
The upper end of the first base 203 is centrally provided with a first arc-shaped bearing table 204, and the first arc-shaped bearing table 204 can bear the rod body 601. One end of the first base 203 is rotatably provided with a sleeve 210, one end of the sleeve 210, which is close to the first arc-shaped supporting table 204, is provided with a clamping cavity 217, and a plurality of clamping blocks 218 are annularly distributed on the cavity wall of the clamping cavity 217. The milling machine fixture mechanism further comprises a first driving mechanism for driving the sleeve 210 to rotate 180 degrees, a pushing mechanism for driving one end of the rod body 601 on the first arc-shaped bearing table 204 into the clamping cavity 217, and a second driving mechanism for driving the clamping block 218 to clamp the end 602.

Then, the first conveying mechanism 201 drives the first base 203 to move below the milling head of the milling machine 106, and after the side groove 603 is machined on the rod body 601, the first driving sleeve 210 drives the rod body 601 to rotate 180 degrees, so that the mounting groove 604 is machined again.
Specifically, the end of the sleeve 210 away from the first arc-shaped supporting table 204 extends out of the first base 203, and a plurality of key grooves 211 are formed in the outer wall. An annular positioning rack 212 is arranged on the sleeve 210 positioned in the first base 203, and the first driving mechanism comprises a first electric push rod 214 which is installed in the first base 203 and used for driving the insertion block 213 to be inserted into the annular positioning rack 212.

When the rod body 601 needs to rotate 180 degrees, the rotating drum 210 can be driven to rotate 180 degrees by driving the rotating seat 411 through the stepping motor 412. When rotation of the drum 210 is not required, the rotation of the drum 210 is restricted by inserting the insertion block 213 into the annular positioning rack 212.
The clamping block 218 is slidably mounted in a radial chute provided in the sleeve 210 in a radial direction, and a first spring 219 is connected between the clamping block 218 and a wall of the radial chute.
