Abstract

The invention discloses a sensor fixing device for thermal error measurement of a numerical control machine tool. A fastening module is arranged on a standard connecting rod and can move along the standard connecting rod; one side of the fastening module is connected with a fine adjustment fixing base of a sensor fine adjustment module; and the fine adjustment fixing base is provided with a support for installing an eddy current sensor. The universality and the thermal error measurement efficiency of the fixing device can be remarkably improved, and the problem that the measurement precision of the eddy current sensor is reduced due to the installation precision is avoided.

Description

technical field [0001] The invention belongs to the technical field of error measurement of numerical control machine tools, and in particular relates to a sensor fixing device for thermal error measurement of numerical control machine tools. Background technique [0002] The error of CNC machine tools is an important factor restricting the improvement of its precision. The manufacturing error caused by thermal deformation can account for 40% to 70%, which is an important part of machine tool error. During the operation of the CNC machine tool, an uneven temperature field will be formed, resulting in local thermal deformation, which will cause the position of the tool and the workpiece to deviate, that is, thermal error. The thermal characteristic test of the machine tool is the detection and identification of the temperature field and deformation of the machine tool. It is the basic project for the thermal error compensation of the machine tool. It can be divided into the t...
