Redundant driving parallel device for machine tool

Abstract

The present invention discloses a new type redundant drive parallel device of a kind of machine tool with several functions, belonging to the field of machinery technology. It is formed from controllable slide block mounted in guideway, length-fixed drive rod capable of driving slide block and making it move in guideway, controllable telescopic shaft and mobile and turnable working table consisting of moving platform for mounting cutting tool and working table for mounting workpiece, and utilizes the drive rod, controllable telescopic shaft, moving platform, slide block and guideway to form the invented redundant drive plane parallel closed link mechanism with several functions of cutting, grinding, load-shifting and assembling, etc. Its structure is simple, and can make moving platform obtain higher regidity.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, in particular to a novel redundant driving parallel device of a machine tool with multiple functions. Background technique [0002] In the field of mechanical manufacturing, traditional machine tool structures, such as cutting machine tools, all have fixed guide rails, and their basic movement mode is to make the tool or workpiece move along the fixed guide rails. This movement mode shared by traditional equipment has brought many inherent defects. For example, traditional machine tools must have high-rigidity bulky and heavy bed, columns and other supporting components and high-precision guide rail systems fixed to the supporting components, resulting in heavy weight of the machine tool. , high price, and difficult to move. In addition, the tandem mechanical mechanism design of the traditional machine tool makes the spatial movement need to be realized by the mutual superpositi...

Problems solved by technology

The flexibility of tool operation in the dominant movement direction of this type of machine tool is significantly different from that in other processing directions. Although this feature is suitable for processing long and complex curved surface workpieces, it is not as good as other types of workpieces. The first category of machine tools has advantages

[0006] However, regardless of whether it is a parallel machine tool driven by a telescopic shaft type inner pair or a parallel machine tool driven by a slider type outer pair, due to the inherent characteristics of the parallel mechanism itself, the working space of the machine tool is much smaller than that of the traditional machine tool, and the machine tools can be realized Attitude ability is also relatively small
