Miniature machine tool with adjustable operating space

Abstract

The invention discloses a miniature machine tool with adjustable operating space. The miniature machine tool comprises a tool body, an X-direction precision displacement platform, a Y-direction precision displacement platform, a Z-direction precision displacement platform, an electric spindle and a workpiece fixture, wherein the tool body comprises a base and a gantry column, the Y-direction precision displacement platform is mounted on the base, the X-direction precision displacement platform is mounted on the Y-direction precision displacement platform, the workpiece fixture is mounted on the X-direction precision displacement platform, a cross beam is arranged at the middle-lower part of the gantry column, a mounting frame is arranged at the middle-upper part of the gantry column, a Z-direction adjusting displacement platform is mounted in the mounting frame of the gantry column, the Z-direction precision displacement platform is mounted in front of the Z-direction adjusting displacement platform, and the electric spindle is mounted in front of the Z-direction precision displacement platform. The miniature machine tool combines advantages of a C-type structure and a gantry structure and optimizes the structures and adopts an inlaying structure, and enlarging adjustment of the operating space of the machine tool is realized by mounting the Z-direction adjusting displacement platform on the gantry column.

Description

technical field [0001] The invention belongs to the technical field of micromachining, and more specifically relates to a micromachine tool with adjustable operating space. Background technique [0002] In recent years, with the rapid development of aerospace, electronic communication, automobile industry, biomedical and other manufacturing equipment technologies, the demand for miniaturized products in the fields of civil and national defense has been increasing, and the characteristic size is from μm to mm. The demand for precise three-dimensional tiny parts is increasingly urgent, and the requirements for the function and reliability of tiny devices are also getting higher and higher. However, due to the limitation of the material, structural shape and production cost of the processed parts, the traditional micro-mechanical electronic system and ultra-precision machining technology are greatly limited. Therefore, the micro-manufacturing technology based on the micro-mach...

Problems solved by technology

[0004] After the micro-milling machine tool is equipped, its operating space is closely related to the stroke of the workbench. In order to ensure that the workbench has better positioning accuracy, repeatability and straightness, and considering the economy and reliability, the stroke of the workbench is generally Smaller, so the operating space of the machine tool is greatly limited, and in the actual processing process, it may be necessary to install auxiliary devices such as pressure sensors, acceleration sensors, and workpiece fixtures on the workbench, so that the operating space and effective working space are reduced. , which brings inconvenience to a series of operations such as measurement and tool change
