The workpiece to be processed is placed on the clamping and fixing structure 4095 through the automatic feeding and discharging structure or the robotic arm, and is firmly clamped by the clamping and fixing structure 4095. When performing processing operations, according to the processing requirements, the guide screw linear rail 402 is driven by the external PLC controller to move the sliding position member 4099 along the guide screw linear rail 402 to the specified linear position, and at the same time, the bidirectional drive motor 4093 drives the synchronous turntable member 4094 to drive the clamping and fixing structure 4095 and the workpiece to rotate to the specified angular position, or when the sliding position member 4099 moves, it drives the bearing frame and the related structures it carries to slide on the surface of the driving slot seat 405. When the sliding position member 4099 reaches the specified position, the external PLC controller activates the micro electromagnetic guide rod 4097 to push the sliding locking block 4098 to move downward. The locking groove 4010 is locked to ensure that the position of the sliding position member 4099 is fixed. At the same time, the position of the sliding position member 4099 and the clamping and fixing structure 4095 can be confirmed to be accurate through the sensors on the position disk 403 and the rotating disk rail 404. When the sliding position member 4099 moves, the rack 409 can be driven to move. The linear motion formed by the displacement of the rack 409 can be used to rotate the meshed adjustment gear 4090 to form an adjustment operation, so that the adjustment gear 4090 can be adjusted in angle and orientation using the steering shaft 4091 and the related structure carried by the synchronous slot frame 4092, so as to actively adapt to the working angle according to the position of the working tool 108, and adapt to the processing requirements of different angles with the cooperation of the rotating disk rail 404, thereby reducing the processing error. At the same time, during the operation, the chip suction pump box 407 absorbs the chips generated during the processing through the chip suction pipe 406, so as to keep the working environment clean, reduce the influence of chips on the processing process, and improve the processing quality and efficiency.
