[0024] Reference Figure 1-5A milling fixture for automobile half-shafts includes a worktable 1. A drive motor 2 is fixedly mounted on the front side wall near the upper end of the worktable 1. A rotating shaft 3 is fixedly connected to the lower end of the drive shaft of the drive motor 2. A milling head 4 is fixedly mounted on the lower end of the rotating shaft 3. When the drive motor 2 is started, the milling head 4 on the rotating shaft 3 rotates and performs milling on the half-shaft workpiece body 15. An electric slide rail 5 is provided on the front side wall at the center of the worktable 1. An electric slide block (not shown in the figure) is slidably connected to the electric slide rail 5. A support platform 6 is fixedly mounted on the front side wall of the electric slide block. When the electric slide rail 5 is started, it works in conjunction with the electric slide block (not shown in the figure) to drive the support platform 6 and the placement platform 7 to move vertically up and down, adjusting the position of the half-shaft workpiece body 15 and the milling head 4. A placement platform 7 is slidably connected to the upper end of the support platform 6. A linear guide rail 8 is fixedly installed at the upper end of the center position of the support platform 6. A movable guide block 9 is slidably connected to the linear guide rail 8. The upper end of the movable guide block 9 is fixedly connected to the lower end of the center position of the placement platform 7. The linear guide rail 8 is set perpendicular to the electric slide rail 5. The linear guide rail 8, together with the movable guide block 9, adjusts the horizontal position of the placement platform 7, so as to quickly adjust the milling position of the half-shaft workpiece body 15 according to actual needs. A PLC controller 10 is fixedly installed on the front side wall of the support platform 6. The drive motor 2, the electric slide rail 5 and the linear guide rail 8 are all electrically connected to the PLC controller 10.

[0025] Clamping mechanisms are provided on the upper front and rear sides of the center position of the placement platform 7. The clamping mechanisms include rectangular slots 11 respectively located on the upper front and rear sides of the center position of the placement platform 7.
