Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. However, the uses and purposes of these exemplary embodiments are only used to illustrate the present invention, and do not constitute any form of limitation to the actual protection scope of the present invention, nor limit the protection scope of the present invention thereto.

[0024] Some orientation words are defined in the present invention. In the case of no contrary description, the orientation words used such as "up, down, left, right" refer to the changeable and quick-knife device provided by the present invention under normal use. defined, and with the attached figure 2 The up, down, left, and right directions shown in are the same. "Inside and outside" refer to inside and outside relative to the outline of each part itself. These orientation words are adopted for easy understanding, and thus do not constitute a limitation to the protection ...

Abstract

The invention discloses a sharp knife device capable of changing knives. The sharp knife device capable of changing the knives comprises a base, a linear motor, a slide part, a grating ruler used for detecting sliding displacement of the slide part, and a drive assembly for driving the slide part to rotate, wherein the slide part comprises a fixed part and a slide part; the fixed part can be rotatably mounted on the base; the drive assembly can drive the fixed part of the slide part to rotate; when the fixed part rotates, the slide part rotates along with the fixed part; one end of the slide part can be rotatably connected onto an output shaft of the linear motor; the other end of the slide part is fixedly equipped with a knife disc; the motion direction of the output shaft of the linear motor is parallel to or superposed with the slide direction of the slide part; and two knives are mounted on the knife disc. The sharp knife device capable of changing the knives provided by the invention also can guarantee part processing precision after changing the knives.

Description

technical field [0001] The invention relates to the technical field of fast-knife servo processing, in particular to a fast-knife device with replaceable knives. Background technique [0002] Optical microstructures are widely used in military and civilian industries, and are closely related to production and life. Since the surface of microstructured optical components is a high-precision, asymmetric surface with complex shapes, traditional processing methods such as imitation, grinding and polishing, etc., have low efficiency. Very low, some can not meet the requirements of technical indicators. Some microstructure surface manufacturing technologies developed in recent years, such as electron beam direct writing technology, laser beam direct writing technology, photolithography technology, etching technology, deposition and image etching technology, LIGA technology, etc., have certain limitations. High requirements on equipment and equipment, unclear edges of etched graph...
