Based on their application range, they include vertical milling machines, horizontal milling machines, gantry milling machines, etc. Milling machines are used almost everywhere and are the cornerstone of modern manufacturing.

[0003] Before machining, the workpiece must be reliably clamped and fixed on the worktable to prevent it from shifting or vibrating under the action of cutting force, thereby ensuring machining accuracy, surface quality and ensuring operational safety. Existing milling machine workpiece clamping mostly adopts rigid clamps such as manual clamping plates and bolts or cylinder-driven clamping arm mechanisms.

[0004] During the clamping process of the workpiece, the accuracy of the workpiece placement angle is also very important. If the angle deviates, the entire workpiece processing will fail. The existing milling machine's swing arm clamping mechanism is difficult to accurately determine the workpiece placement angle.

Drive motor four 715 to drive the rear abutment plate 716 to deflect, so that the front abutment plate 78 and the rear abutment plate 716 drive the workpiece to deflect to a suitable angle. S3. Position the workpiece, rotate the rotating arm 51 to above the workpiece, place two abutting blocks above the workpiece, drive the transverse hydraulic cylinder 52 to drive the transverse hydraulic shaft 53 to abut one of the abutting blocks, drive the sliding cylinder 58 to drive the movable seat 54 to slide towards the workpiece, drive the longitudinal hydraulic cylinder 55 to drive the longitudinal hydraulic shaft 56 to abut the other abutting block, and complete the positioning of the workpiece. S4. Adjust the positions of the front abutment plate 78 and the rear abutment plate 716, drive the first motor to drive the first screw to rotate in the opposite direction, drive the second motor to drive the second screw to rotate in the opposite direction, and under the connection of the front slide plate 72, the first screw, the front slide block 75, the front abutment plate 78, the rear slide plate 710, the second screw, the rear slide block 713, and the rear abutment plate 716, so that the front abutment plate 78 and the rear abutment plate 716 are away from the workpiece; S5. The workpiece is processed by driving the processing table 2 to slide towards the milling head device 3. The processing table 2 drives the workpiece to slide towards the milling head device 3, and the milling head device 3 is driven to process the workpiece.
