Combined heavy machine tool foundation settlement precision detection device

Abstract

The invention discloses a combined heavy-duty machine tool foundation settlement precision detection device, and belongs to the field of heavy-duty machine tool foundation settlement precision detection. According to the structural characteristics of the heavy numerical control machine tool, main stress areas of the foundation are respectively designed into a combined structure of a plurality of foundation sub-blocks, optical fiber sensors are laid in the foundation sub-blocks to detect the bearing deformation of the foundation, the single optical fiber sensor is convenient to install, and the detection precision is higher; and the combined type basic block can realize replacement of a single basic sub-block. The optical fiber sensors are led out through the foundation block preformed grooves and connected into the multi-channel acquisition equipment in parallel, when the optical fiber sensors are damaged, the foundation blocks with problems can be conveniently and rapidly positioned, and finally data acquisition of foundation settlement is achieved through a distributed optical fiber sensing system. The experimental device adopts the adjustable foundation box, so that the rigidity requirement of the combined foundation block is ensured.

Description

technical field [0001] The invention relates to the technical field of heavy-duty numerical control machine tool foundation settlement detection, in particular to a combined heavy-duty machine tool foundation settlement precision detection device. Background technique [0002] The concrete foundation is the carrier of heavy-duty CNC machine tools, and its load-bearing deformation directly affects the working accuracy and life of machine tool components. In order to ensure the accuracy, it is generally required that the inclination of the basic part of the bed rail in the longitudinal direction is not more than 0.005mm. For the high-precision design requirements, it is necessary to match the high-precision detection method. The traditional detection method can no longer meet the detection requirements in terms of sensor assembly and test accuracy. The fiber optic sensor with high measurement sensitivity and strong anti-interference ability is laid in the concrete foundation. ...
