A micro-precision machine tool capable of processing free-form surfaces at one time

Abstract

The invention discloses a micro-precise machine tool capable of processing free-form surfaces at one time, which is characterized in that it includes a frame, a vibration-damping base, a drive assembly, a cutter head assembly, a workbench and a fixture. The frame is placed on the damping base, and the processing head assembly is installed in the inner chamber of the regular triangular pyramid surrounded by the frame; the X-direction and Y-direction linear motors, hydraulic cylinder piston rods and gear pairs of the drive components are coordinated , cooperation, can drive the workpiece to be processed to move forward, backward, left, and right, flip along the vertical direction and rotate along the horizontal plane; the cutter head assembly moves up and down under the drive of the Z-direction linear motor: after the workpiece to be processed is clamped and fixed once, it can be Complete machining of flat or free-form surfaces. The main part of the present invention is all installed in an extremely stable tetrahedron structure space, which has the characteristics of compact structure, reasonable layout, high processing precision, good reliability and stability, and can complete the processing and forming of free-form surfaces at one time.

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.
