Rotatable single-station multi-process drilling and milling integrated pneumatic fixture for high-pressure oil pump seat

The utility model belongs to mechanical manufacturing process equipment, and particularly relates to a rotatable single-station multi-process drilling and milling integrated pneumatic fixture for a high-pressure oil pump seat. A rotatable flange connecting disc on the flange connecting disc rotation driver is fixedly connected with a connecting side plate, the lower end face of the connecting side plate is fixedly connected with a gas circuit base plate, every two supporting columns and every two limiting supporting columns are symmetrically arranged in an oblique angle mode, and pneumatic lever cylinders are installed on the gas circuit base plates on the left side and the right side of the heightening block respectively. The rotatable single-station multi-procedure drilling and milling integrated pneumatic clamp for the high-pressure oil pump seat is simple in structure, two sets of tools for machining in two procedures in the past are combined into one set of tool for machining in one procedure, manual pre
