Experimental device and method for adjusting bed accuracy by static pressure pad iron

Abstract

The invention provides an experiment device and a method for accuracy of static pressure sizing block regulation and control bed. In the experiment device, a basic model box is divided into a plurality of small rooms. The pre-fabricated plates are arranged on the upper part of each small room and are capable of sliding along the vertical guide rails inside the rooms. Each small room is provided therein with a vertical deformation device which is controlled to rise and fall by a nearby hydraulic system. A displacement sensor (a) and a pressure sensor (a) are adhered to the left side and the right side of the vertical deformation device respectively. On the upper surface of the basic model box, the bed body is connected with the basic model box through the cylindrical sizing block and the sliding rods inside the sizing block. A displacement sensor (c) and a displacement sensor (d) are both adhered to the outer surface of the bed body. The sliding rods are in the cylindrical sizing block and are controlled to rise and fall by the hydraulic system. A displacement sensor (b) and a pressure sensor (b) are both adhered to the outer side of the cylindrical sizing block. The basic model simulates the uneven sediment and fall of a base simply and according to the different experiment requirements, the sediment amount of the base and the sediment speed can be regulated. The experiment device is simple in construction, low in cost, and strong in operation. Therefore, the experiment device can be applied to experiments widely.

Description

technical field [0001] The present invention relates to the field of bed precision in the foundation-machine tool system, also relates to the connection structure between the foundation and the bed - pad iron, and more to an experimental method for the pad iron to regulate the accuracy of the bed, which can be applied to the field of experimental equipment. Background technique [0002] In recent years, with the implementation of several 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 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. High-precision machine tools are an important basis for processi...

Problems solved by technology

Although the city test in this case can intuitively reflect the problem of uneven settlement, the cost is high and it is difficult to carry out repeated experiments under the control of multiple influencing factors. Model experiments can guarantee this advantage. Therefore, it is necessary to study experimental methods that can control the accuracy of the bed

[0003] The traditional basic structure and machine tool connection - pad iron is placed directly through the anchor bolts, there is no control function, and it is impossible to control the slight changes of the bed
