Rotary valve body machining clamp

The utility model provides a rotary valve body machining clamp which comprises a platen and a clamp body installed on the platen, clamping grooves used for containing a rotary valve body are distributed in the side end of the clamp body, and clamping blocks used for containing the rotary valve body are distributed at the upper end of the clamp body so that different faces of the rotary valve body can be machined. And a first clamping assembly for fixing the rotary valve body is arranged on one side of the table plate corresponding to the clamping groove. The clamp bodies are distributed to be used for installing the rotary valve body through the clamping grooves and the clamping blocks, the first clamping assembly is matched with the clamping grooves to fix the rotary valve body, the second clamping assembly is matched with the clamping blocks to fix the rotary valve body, and therefore the different end faces of the rotary valve body can be fixed upwards; and therefore, the multiple end faces of the rotary v
