[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figures 1 to 3 , the utility model provides a technical solution:

[0019] A profile milling fixture comprises a workbench 1 and a plurality of clamping assemblies which are detachably mounted on the workbench 1 in sequence, the clamping assembly comprising a U-shaped frame 2 detachably connected to the workbench 1, a placement seat 3 mounted above the U-shaped frame 2, a first fixing frame 4 and a second fixing frame 5 mounted on the placement seat 3, a screw 6 threadedly connected to the first fixing frame 4 and the second fixing frame 5 respectively, and a pressing plate 7 mounted at one end of the screw 6, the first fixing frame 4 is fixedly connected to the placement seat 3, a slide groove is provided inside the placement seat 3, the second fixing frame 5 is slidably connected to the slide groove, and a moving mechanism for driving the second fixing frame 5 to slide is provided below the slide groove.

[0020] During operation, the profile is first placed on the placement seat 3 on the corresponding clamping assembly according to its overall length, and one side of the profile is in contact with the first fixing frame 4. Then, the second fixing frame 5 is driven by the moving mechanism to slide in the slide groove until it contacts the other side of the profile. Then, the screw 6 is rotated to drive the pressing plate 7 to move toward the profile and contact the top of the profile, thereby realizing multi-directional fixed clamping.

[0021] The moving mechanism includes a rotating shaft 8 rotatably mounted in the placement seat 3 and a sliding sleeve 10 sleeved on the outside of the rotating shaft 8 and connected to the second fixing frame 5. The outer surface of the rotating shaft 8 is provided with a thread groove which is spirally connected to the sliding sleeve 10.

[0022] A drive box is installed on one side of the placement seat 3, and one end of the rotating shaft 8 passes through the drive box and is installed with a gear 11. One side of the gear 11 is meshed with a gear 2 12, and the gear 2 12 is installed on a movable shaft, and one end of the movable shaft is connected to the output end of the servo motor.

[0023] The servo motor drives the gear 2 12 to rotate, and the gear 2 12 drives the gear 1 11 to rotate, thereby driving the rotating shaft 8 to rotate, so that the sliding sleeve 10 moves horizontally on the rotating shaft 8, thereby adjusting the position of the second fixing frame 5 so that it can be pressed against the profile, avoiding direct connection between the rotating shaft and the servo motor, which is easy to shake and reduces the firmness and stability of the clamping.

[0024] A rubber pad is installed under the pressing plate 7 to prevent slipping and wear when it is fixed.

[0025] The U-shaped frame 2 and the workbench 1 are fixed by bolts, which is convenient for installing and disassembling the clamping components and facilitating subsequent inspection and maintenance.
