More Information
Summary:The invention discloses a broaching machining device and a broaching machining method and belongs to the field of workpiece machining. The broaching machining device comprises a positioning assembly and a machining tool. The positioning assembly comprises an annular positioning plate and a positioning block. The positioning plate is coaxially arranged in an inner cylinder, the positioning block isarranged on the end face of the end, close to a datum hole, of the positioning plate. The positioning block is provided with a positioning hole, and the positioning hole is opposite to the datum hole. The machining tool comprises a guide rod, a cutting part and a clamping part which are all sequentially and coaxially connected in the axial direction. The guide rod coordinates with the positioninghole so that the cutting part can move in the axial direction of the positioning hole in the process of machining the datum hole, the precision and the coaxiality of a hole during broaching machiningcan be guaranteed, and the
