Four-axis multi-station numerical control machine tool

Abstract

The invention provides a four-axis multi-station numerical control machine tool which comprises a machine tool body and a first motor, sliding rails are arranged on the machine tool body in a bilateral symmetry mode, sliding tables are arranged on the sliding rails in a sliding fit mode in a front-back moving mode, and a screw in threaded connection with the sliding tables is in keyed connection with an output shaft of the first motor; a sliding table is arranged on the machine tool body, a rotary table driven by a second motor to rotate is arranged on the sliding table, a positioning plate is arranged on the rotary table, a material clamping assembly is arranged on the positioning plate, a longitudinal moving piece driven by a servo electric cylinder is arranged on the machine tool body, and an inclined moving assembly matched with the sliding rail in a sliding mode is arranged on the longitudinal moving piece in an elastic pre-pressing mode. And a material supporting assembly is arranged on the inclined moving assembly. The pre-assembling device has the advantages that the pre-assembling of the workpiece can be completed during machining, the workpiece on the positioning plate can be automatically loosened and clamped, the workpiece on the material supporting assembly is loosened after the workpiece is obliquely moved to the positioning plate, and the efficiency is improved.
