[0002] In the field of mechanical processing, tool wear directly affects processing accuracy and efficiency, and regular grinding is a key link in maintaining tool performance. However, traditional grinding devices generally have the following problems: manual adjustment of the tool angle of the fixture relies on operating experience, and it is difficult to accurately control the contact angle between the blade and the grinding wheel, which can easily lead to secondary wear or uneven grinding; the clamping mechanism used for grinding is mostly a fixed design, and repeated disassembly and adjustment are required when grinding multi-blade tools, which is time-consuming and has poor repeated positioning accuracy. After searching, it was found that a Chinese patent with announcement number CN103846742A discloses a tool grinding processing device. In this patent, the operator clamps the tool to be sharpened on the C-axis axial device, and adjusts the vertical height of the spindle through the Z-axis axial device, the B-axis axial device drives the swing angle of the grinding wheel group, and the X / Y-axis axial device controls the relative position of the tool and the grinding wheel; after starting, the spindle motor drives the grinding wheel group to rotate at high speed, and the water pump of the filter water tank continuously sprays coolant through the nozzle. At the same time, the C-axis drives the tool to rotate precisely and move in coordination so that the grinding wheel accurately contacts the tool edge, and the automatic sharpening of the passivation surface is completed through the trajectory set by the CNC program. However, the transmission structure of this patent is complex, the equipment manufacturing cost is high, and the maintenance and debugging are difficult.
