The invention relates to a turning and milling combined machining machine tool for a ball screw type electric steering gear nut. The turning and milling combined machining machine tool comprises a base, a fixedly-arranged main machining unit, a movably-arranged auxiliary machining unit and a plurality of machining tools; the main machining unit comprises a main machining base which is fixedly arranged on the base, a main machining chuck which is arranged on the main machining base and a plurality of main flexible clamping jaws which are arranged on the main machining chuck; the auxiliary machining unit comprises an auxiliary machining base which is movably arranged on the base, an auxiliary machining chuck which is arranged on the auxiliary machining base and a plurality of auxiliary flexible clamping jaws which are arranged on the auxiliary machining chuck; and the auxiliary flexible clamping jaws are further provided with receding grooves for avoiding interference between the machining tools and the clamping jaws. Compared with the prior art, the turning and milling combined machining machine tool for the ball screw type electric steering gear nut can integrate multiple machiningprocedures such as outer circle turning machining, drilling machining and inner spiral ball groove machining into one device, so that the production process is simplified, the problem that the size precision of a workpiece is unstable due to repeated clamping is avoided, the production efficiency is greatly improved, and energy consumption is remarkably reduced.
Description
Technical field [0001] The invention belongs to the technical field of automobile parts processing, and relates to a turning and milling compound processing machine tool for a ball screw type electric steering gear nut. Background technique [0002] The nut processing of automobile ball screw type electric power steering gear is relatively complicated. Usually, a lathe is required to complete the internal and external turning processing, the drilling machine or machining center drilling processing, the CNC milling machine or processing center to complete the reversing groove milling, and the turning center to complete the inner spiral ballway large pitch. Precision machining and a multi-axis machining center with a three-dimensional rotating worktable can complete the internal spiral ballway transition arc three-dimensional machining and other processes and multiple complex equipment can be completed, the processing process is long, repeated clamping causes the dimensional accurac...
