Abstract

The invention discloses an experimental device for adjusting machine tool foundation precision. A container is fixed on a foundation, and is fully filled with hydraulic coil; a large-diameter cylinder is a hollow solid, and is positioned in an upper surface opening of the container fully filled with the hydraulic coil; a small-diameter cylinder is positioned in the hollow of the large-diameter cylinder, is smoothly contacted with the large-diameter cylinder, and can slide up and down under pressure of the hydraulic oil; a pressure sensor A is bonded on the outer side of the large-diameter cylinder by glue; according to the data of the pressure sensor, a hydraulic pump controls the ascending height of the small-diameter cylinder through adjusting the pressure of the hydraulic oil container by a control valve; an anti-leaking ring can prevent leakage of the hydraulic oil to guarantee tightness of the container; a fixed ring is used for fixing the large cylinder to guarantee a up-down reciprocating motion of the large cylinder; and a pressure sensor B is used for detecting the pressure change of the hydraulic oil container, and can adjust the oil pressure of the container according to the pressure change, so that the ascending height of the small-diameter cylinder is adjusted, the stability of the machine tool foundation precision is guaranteed, and the experimental accuracy is improved.

Description

technical field [0001] The invention is an experimental device for controlling the foundation precision of a machine tool, which relates to the fields of heavy machine tool manufacturing and foundation research. Background technique [0002] In recent years, with the implementation of a number of key special programs by the State Council, the government has continued to increase investment in key projects such as aerospace, nuclear power and wind power, railway locomotives, ships, and transportation. The key components of engineering equipment are all large-scale, heavy-tonnage, and high-precision workpieces. To undertake the processing of such typical components, it is necessary to develop high-level large-scale, heavy-duty, and super-heavy CNC machine tools. As the requirements for machining accuracy of machine tools are getting higher and higher, it is very important to establish an accurate machining accuracy model, especially for heavy-duty machine tools, which have lar...
