[0019] Before the operation, the present invention needs to make the profiling guide rail 2 according to the shape of the required workpiece. In this example, the deep loosening tooth cutting of the deep loosening machine in agricultural machinery is taken as an example. The workpiece 6 to be processed is fixed on one side of the mobile platform 5 through a clamping mechanism. The distance between the two vertical plates of the profiling guide rail is just equal to the width of the mobile platform 5, so that it can be constrained to move on the profiling guide rail 2 through the guide bearing 3 and the support bearing 4. When the device is running, the motor 12 drives the displacement screw 9 to rotate through the transmission belt 11, the reversing reduction gear box 10, and the displacement driving gear 8. Since the displacement driving gear 8 is mounted on the displacement screw 9 The inner wall of the center hole of the displacement driving gear 8 is threadedly connected with the displacement screw 9. Therefore, when the displacement driving gear 8 drives the displacement screw 9 to rotate, the displacement driving gear 8 and the displacement screw 9 will also move relative to each other, that is, the displacement screw 9 moves along the axis, and at the same time, the displacement screw 9 lifts the movable platform 5 forward and moves the movable platform 5 on the profiling guide rail 2. Since the profiling guide rail 2 is consistent with the contour of the required workpiece, the moving trajectory of the movable platform 5 is the contour line of the required workpiece. At this time, the cutter 7 fixed on the movable platform 5 moves with the movable platform 5. The cutter 7 cuts the workpiece 6 to be processed, and the final processed workpiece is consistent with the contour of the required workpiece. In order to make the distance between the cutter 7 and the workpiece 6 to be processed the most reasonable to ensure the cutting size, a moving plate 17 is installed on the moving platform 5, on which the cutter 7 is fixed. Pull the lateral displacement handle 19, and the moving plate 17 moves left and right on the moving platform 5, but the movement amount is limited by the position bolt 18. Since the external contour of some required workpieces fluctuates, the moving trajectory of the moving platform 5 on the profiling guide rail 2 also fluctuates. At this time, it is necessary The power mechanism that provides power for the mobile platform 5 can change its angle along the moving trajectory of the mobile platform 5. Therefore, a steering mechanism is provided at the lower part of the power mechanism, that is, when the entire power mechanism swings up and down on the mobile platform 5, it drives the power mechanism to swing up and down, and the gearbox fixing seat 14 of the steering mechanism is installed on the rotating shaft support frame 21 through the gearbox base rotating shaft 20. Therefore, when the power mechanism swings up and down, it drives the gearbox fixing seat 14 to swing up and down on the rotating shaft support frame 21. At this time, the power mechanism and the mobile platform 5 swing up and down together.
