Step 1: Store the cutter head (36) in the storage slot (5) respectively. When storing, insert the cutter head (36) into the slot (35) first, and then use the clamping block (42) to hold the first card groove (43), so that the cutter head (36) can be stably fixed inside the storage groove (5);

The second step; when the appropriate cutter head (36) needs to be selected, the first transmission roller (8) and the second transmission roller (9) can be driven to rotate by the first servo motor (12) and the second servo motor (13), In this way, the storage sphere (4) stuck inside the fixing ring (3) can be adjusted at multiple angles through the first transmission roller (8) and the second transmission roller (9), so that the position where the cutter head (36) is required can be adjusted. The storage tank (5) can be turned upward, and when the first servo motor (12) and the second servo motor (13) are powered on to drive the first transmission roller (8) and the second transmission roller (9) to rotate. The electromagnet (49) is also energized to work, so that the iron sheet (50) can be adsorbed by the electromagnet (49), so that the second telescopic rod (46) shrinks, so that the pressing plate (47) no longer squeezes the storage sphere (4) surface, so that the first transmission roller (8) and the second transmission roller (9) can drive the rotation shaft of the storage sphere (4) to prevent excessive friction from reducing the service life of the device, and the angle adjustment of the storage sphere (4) After completion, the extrusion rod can be reset and squeezed the storage ball (4) under the action of the second telescopic rod (46) and the second inner spring (48), so as to ensure that the storage ball (4) does not have the first transmission roller (8) Under the driving action of the second transmission roller (9), the rotation will not occur;

Step 3: Clamping the cutter head (36), when clamping the cutter head (36), the first robotic arm (20), the second robotic arm (22) and the adjusting head (23) can be rotated to adjust the housing ( 24) It can be vertically facing the storage slot (5) where the cutter head (36) needs to be taken, and then insert the housing (24) into the storage slot (5), and the housing (24) will pass the inclined surface during insertion. Squeeze the pressing block (40), so that the first telescopic rod (39) can be contracted, and then the clamping block (42) can be moved out of the first clamping groove (43) and the first clamping groove (43) can no longer be fixed. ), and when the housing (24) is inserted into the storage slot (5), the second mounting lever (34) will be snapped into the housing (24) accordingly, and the third servo motor ( 26) Drive the rotating disc (27) to rotate clockwise, so that the movable rod (29) can be pushed to open to both sides by the transmission rod (32), so that the clamping rod (34) can be opened to both sides, and the second After the installation rod (38) is completely inserted into the bottom of the casing (24), the third servo motor (26) is controlled to reset, so that the clamping rod (34) can be inserted into the second clamping slot (44), and then the After completing the clamping of the cutter head (36), the control housing (24) can then be pulled out from the storage tank (5);

Step 4: Put the cutter head (36) back, and when the cutter head (36) is put back, the third step is to insert the cutter head (36) into the storage slot (5). The casing (24) is squeezed to open, and after the cutter head (36) is inserted into the slot (35), the casing (34) can be pulled out so that the clamping rod (34) is no longer stuck in the second clamping slot (44). body (24), so that the clamping block (42) can be automatically clamped into the first clamping groove (43) after the casing (24) is pulled out to complete the fixing of the cutter head (36), and the whole use process is convenient and quick.
