Gear grinding equipment for spiral bevel

The utility model discloses gear grinding equipment for a spiral bevel. The gear grinding equipment comprises a machine tool, a clamping device, a grinding device, a drilling arm, a Y-axis linear module and a translation mechanism, the clamping device is arranged on the translation mechanism and is driven by the translation mechanism to linearly move; the grinding device is mounted on the drillingarm through a Y-axis linear module and is positioned above the translation mechanism; the clamping device comprises a base table, a left clamping seat, a right clamping seat, a clamping air cylinderand a rotating air cylinder. The left clamping seat is fixedly arranged on the base table; the right clamping seat is connected to the base table in a sliding mode and is driven by the clamping air cylinder to move towards the left clamping seat to clamp a to-be-machined workpiece located between the left clamping seat and the right clamping seat. A workpiece to be machined is driven by the rotaryair cylinder to rotate. Th
