7. The graphite product flipping processing equipment according to claim 3, characterized in that, The positioning mechanism (4) also includes two limiting grooves (411), which are respectively opened on the bottom left and right sides of the inner cavity (412), and the bottom of the trapezoidal block (43) is slidably connected to the limiting grooves (411).

8. The graphite product flipping processing equipment according to claim 1, characterized in that, A controller (6) is fixedly connected to the rear right wall of the positioning platform (1). The controller (6) is electrically connected to the electric telescopic rod (41), the second motor (31), and the first motor (25).

9. The graphite product flipping processing equipment according to claim 1, characterized in that, The positioning platform (1) has fixed plates (7) fixedly connected to the bottom front and rear ends on both sides, and the top of the fixed plate (7) has a mounting hole (8).

10. A method for processing graphite products, characterized in that, A graphite product flipping processing device according to any one of claims 1-9 includes the following steps: S1. First, put the graphite blank into the upper positioning groove (22). Use the right angle between the bottom corner of the upper positioning groove (22) and the graphite blank to achieve accurate positioning for the first clamping. After positioning, process the exposed side of the graphite blank through an external three-axis machining equipment. S2. After the side processing is completed, start the electric telescopic rod (41). The electric telescopic rod (41) drives the support plate (42) and the trapezoidal blocks (43) on both sides to move forward. The trapezoidal blocks (43) drive the movable block (45) in its slide groove (44) to move forward. Due to the inclined structure of the slide groove (44), the movable block (45) moves upward while moving forward. The movable block (45) drives the support rod (46) and the push block (48) to lift the flat workpiece (23) until the workpiece (23) is pressed against the stop strip (49) on the bracket (5) and fixed, so that the insert plate (24) is adjusted to a horizontal state. Then, the same three-axis processing equipment is used to perform countersunk hole or engraving and other detailed processing on the horizontal insert plate (24). S3. After the insert plate (24) is processed and reset, start motor two (31). Motor two (31) drives the bidirectional lead screw (33) to rotate, thereby driving the sliders (34) on both sides to move in opposite directions. The sliders (34) push the movable plate (36) to rotate through the connecting rod (35), causing the clamping plate (37) to approach and press the insert plate (24) against the inside of the insert plate (24) on the workpiece (23). The rubber sheet (38) achieves non-destructive and firm clamping. After clamping is completed, start motor one (25). Motor one (25) drives the spur gears (27) on both sides to rotate through the transmission shaft (26). The spur gears (27) mesh with the half gears (29), thereby driving the bracket (5) and the clamped workpiece (23) to flip as a whole until the workpiece (23) is snapped into the lower positioning groove (21). At the same time, the insert plate (24) engages with the slot (210) to complete the secondary precise positioning after flipping. Then the other side of the workpiece (23) can be processed.
