Numerical-control machine tool capable of realizing non-rotary curved-surface turning and milling combined machining

Abstract

The invention relates to a numerical-control machine tool capable of realizing non-rotary curved-surface turning and milling combined machining. The numerical-control machine tool comprises a machinetool bed, a suspension wall column, a cross sliding table workbench, a double-shaft rotary workbench, a turning machine head, a milling machine head, a turning tool magazine and a milling tool magazine, wherein the suspension wall column is of an inverted L-shaped structure composed of a cantilever end and an upright post end, and the upright post end is fixed on the machine tool bed; the cross sliding table workbench is mounted on the machine tool bed, and the double-shaft rotary workbench is mounted on the cross sliding table workbench and can perform reciprocating feeding along the X-axis and the Y-axis under the action of an X-axis driving system and a Y-axis driving system along with the cross sliding table workbench; the turning machine head and the milling machine head are arrangedon the front end face of the cantilever end side by side, and can reciprocate up and down along the Z axis respectively; and the turning tool magazine and the milling tool magazine are respectively arranged on the left side and the right side of the suspension wall column corresponding to the turning machine head and the milling machine head. The numerical-control machine tool is simple in structure and high in response speed, and five-axis curved surface turning and five-axis linkage milling machining can be achieved.

Description

technical field [0001] The invention belongs to the field of numerical control processing equipment, and in particular relates to a numerical control machine tool capable of realizing compound turning and milling of non-revolving curved surfaces. Background technique [0002] With the increasingly fierce competition of electronic products, the requirements for the surface finish of the shell are getting higher and higher. Since the traditional milling cutter is discontinuous cutting, it is difficult to achieve the required surface finish during milling, and subsequent treatments such as polishing are required to reduce the improved processing efficiency. Since the top and side surfaces of electronic product housings are mostly non-revolving surfaces, traditional turning machine tools and turn-milling compound machine tools can only turn workpieces with rotary features, and it is difficult to turn non-revolving surfaces; and the existing The driving structure of the turning ...

[0002] With the increasingly fierce competition of electronic products, the requirements for the surface finish of the shell are getting higher and higher. Since the traditional milling cutter is discontinuous cutting, it is difficult to achieve the required surface finish during milling, and subsequent treatments such as polishing are required to reduce the processing efficiency

Since the top and side surfaces of electronic product housings are mostly non-revolving surfaces, traditional turning machine tools and turn-milling compound machine tools can only turn workpieces with rotary features, and it is difficult to turn non-revolving surfaces; and the existing The driving structure of the turning head of the turn-milling compound machine tool is complex, and some are installed together with the milling head, resulting in heavy weight of the moving parts, slow response speed, difficult to achieve high acceleration, and unable to meet the processing requirements of non-revolving surfaces.
