Micro precision machine tool capable of finishing machining free curved surface at time

Abstract

The invention discloses a micro precision machine tool capable of finishing machining a free curved surface at a time. The micro precision machine tool capable of finishing machining the free curved surface at a time is characterized by comprising a rack, a shock absorbing base, a driving assembly, a tool bit assembly, a workbench and a clamp. The rack is placed on the shock absorbing base; a machining head assembly is installed in a normal-triple-prism inner cavity defined by the rack; an X direction linear motor, a Y direction linear motor, a hydraulic cylinder piston rod, a gear pair and the like of the driving assembly coordinate and cooperate with each other, and a to-be-machined piece can be driven to move in the front, back, left and right directions, to overturn in the vertical direction, and to rotate along the horizontal plane; the tool bit assembly is driven by a Z direction linear motor to move up and down; and after the to-be-machined piece is clamped and fixed one time, machining of a plane or the free curved face can be completed. The body portion of the micro precision machine tool capable of finishing machining the free curved surface at a time is all installed in a tetrahedron structure space which is quite stable, and the micro precision machine tool capable of finishing machining the free curved surface at a time is compact in structure, reasonable in arrangement, high in machining precision, good in reliability and stability, capable of finishing machining and forming the free curved surface at a time, and the like.

Description

technical field [0001] The invention relates to a machine tool and a control and process method, in particular to a machine tool for processing free-form surfaces, belonging to the technical field of micro-nano machining. Background technique [0002] With the development of modern intelligent technology, micro-small precision products are becoming more and more common, and the shape of products tends to be diversified, especially more and more free-form surface parts, such as optical lenses, micro-camera lenses, micro-mirror arrays, automotive headlights, etc. . [0003] General machine tools have limited scope of application, such as grinding machines, milling machines, etc., which have single functions and cannot complete the processing of free-form surfaces at one time, resulting in low production efficiency and high processing costs. [0004] At the same time, the ordinary machine tool structure takes up a lot of space when placed, and the internal structure is not com...

Problems solved by technology

[0006] However, increasing the flexibility of the tool position may cause the machine tool to change the direction of force. Once this change is too large, it will cause vibration of the machine tool during the machining process, which will reduce the machining accuracy of the parts, which does not meet the processing function requirements of micro-sized parts.
