Embodiment Construction

[0020] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0021] The present invention is applied to the fourth axis of CNC machine tools, see Figure 4 , the complex workpiece is processed through the four-axis linkage of the CNC machine tool. When working, the present invention achieves multi-faceted processing of the complex workpiece 500 through rapid positioning and clamping with the machine tool, eliminating the need for conventional technology. The installation error of the fixture under multiple clamping conditions improves the processing quality of the complex workpiece 500 and the processing efficiency of the CNC machine tool, and is especially suitable for processing workpieces with complex shapes such as shells.

Abstract

The invention discloses a fixture with a function of completing machining of a complex workpiece by one-time clamping. The fixture is applicable to a fourth shaft of a numerically-controlled machine tool to realize multi-surface machining of the complex workpiece by one-time clamping. The fixture comprises a base datum plate structure, an auxiliary clamp and a cover plate component, the auxiliary clamp is used for realizing quick combination with the base datum plate structure, and the cover plate component is disposed in the auxiliary clamp. The fixture is ingenious in design and reasonable in structure, and machining of front and back faces and side faces of the workpieces can be realized by one-time clamping. In addition, the scheme for solution of clamping techniques is provided to realize that workpiece replacement time and production auxiliary time can be shortened in a complex workpiece machining process, workpiece clamping precision is guaranteed, and improvement of production efficiency is promoted. Furthermore, high efficiency and low labor intensity in use of the fixture can be realized beneficially.

Description

technical field [0001] The invention relates to a fixture which realizes one-time clamping and processing of complex workpieces. Background technique [0002] With the development of science and technology, the requirements for machining accuracy of workpieces are getting higher and higher, especially for workpieces with complex shapes such as shells. How to make an ideal product not only requires high-precision machine tools, but also requires a mature process, and puts forward high requirements for the rationality of the fixture structure. The use of fixtures is developing in the direction of high efficiency and low labor intensity. [0003] In the past, in the field of mechanical processing, many workpieces required special fixtures for processing. If a general-purpose fixture is used, for workpieces that must be processed on multiple sides, one surface needs to be processed and then removed from the fixture. The next surface can only be processed after re-clamping. Th...
