Mechanical interface device of machine tool module

Abstract

The invention discloses a mechanical interface device of a machine tool module. The mechanical interface device comprises a base body and an interface connecting plate, wherein the interface connecting plate is mounted above the base body; three groups of primary supports and a group of auxiliary supports are arranged on positions, close to four corners, between the base body and the interface connecting plate; and an equal-pressure pulling and pressing mechanism is further arranged between the base body and the interface connecting plate. According to the mechanical interface device of the machine tool module disclosed by the invention, the three groups of primary supports and one group of secondary supports are combined with the equal-pressure pulling and pressing mechanism, so that geometric accuracy and rigidity after the assembled modularized machine tool are regulated with a relatively large range, and interface rigidity and the interface plane can be flexibly regulated according to practical processing conditions, and therefore, practical processing needs of products are met. The mechanical interface device is simple in structure, convenient to operate, and accurate and firm to position.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and relates to a machine tool module mechanical interface device. Background technique [0002] In recent years, the market demand for new products is developing towards diversification, high quality, low cost, and short delivery cycle. New products of the same part family are rapidly updated and emerge in endlessly, and the life cycle of products is becoming shorter and shorter. In order to maintain vigorous competitiveness in the increasingly fierce competition, enterprises have higher and higher requirements for product processing. There are three main requirements, namely, high-quality production, high efficiency and low cost. In this situation, in order to cope with the mass customization production mode, enterprises use a large number of CNC machine tools, machining centers and other equipment with high processing flexibility but expensive equipment to build production lines, w...

Problems solved by technology

[0005] The purpose of the present invention is to provide a kind of machine tool module mechanical interface device, solved prior art machine tool module when carrying out interface connection, because the limitation of original mechanical interface design, under the changeable processing condition (machine tool structure diversity, processing Diversity of loading conditions, etc.), the geometric accuracy and stiffness adjustment of the machine tool after assembly are greatly restricted, and the module joint has a great influence on the dynamic characteristics of the machine tool
